Introduction

Stephanie Chuang, The Patient Story Founder

Stephanie Chuang: My name is Stephanie Chuang. I’m the founder of The Patient Story. The genesis of The Patient Story was my non-Hodgkin lymphoma diagnosis at 31 years old. I remember how overwhelmed I felt and didn’t even know what questions to ask my doctor. What do I do? Where do I go? But it was more like what do we do? Where do we go? Because as we all know, a cancer diagnosis impacts so much more than the patient.

We know there are so many things to consider, but I believe the core of what can make a difference is empowering ourselves to be more active in our care. I’m so thankful for advocates in every form, including other patients, care partners, and healthcare providers who invest so much time and energy in ensuring that we get the best care and know what clinical trials may be an option for us and not as a last resort.

This program is produced by The Patient Story in collaboration with The Leukemia & Lymphoma Society, an incredible advocacy organization that has free resources for patients and care partners in blood cancers, and an organization that has supported more than 85% of blood cancer treatments approved by the FDA to date.

Robyn Stacy-Humphries, 3x DLBCL Survivor

Dr. Robyn Stacy-Humphries: I’m Robyn Stacy-Humphries, a three-time diffuse large B-cell lymphoma survivor. I’m one of the first patients in the United States who received CAR T-cell therapy in 2016.

Nilanjan Ghosh, MD, PhD

Dr. Nilanjan Ghosh: I’m Nilanjan Ghosh, the head of hematology at Levine Cancer Institute at Atrium Health. I also lead the lymphoma division. It’s a real pleasure to be here to discuss DLBCL as well as follicular lymphoma with my colleagues.

Kulsum Bano, MD

Dr. Kulsum Bano: I’m Kulsum Bano, a community oncologist who works at Levine Cancer Institute. It’s a privilege to take care of patients with lymphoma and an honor to be here to talk to everyone. Thank you.

Justin Favaro, MD, PhD

Dr. Justin Favaro: I’m Justin Favaro, a physician, medical oncologist, and hematologist in Charlotte, North Carolina. I’ve been in private practice for 18 years. I see a wide spectrum of different types of cancer, with a special interest in malignant hematology, lymphoma, and leukemia. I love the science of this disease and the technology, and I love to learn more from you all as we try to tell you what we know about this disease. It’s a pleasure to be here. 

Diffuse Large B-cell Lymphoma (DLBCL)

Robyn: Diffuse large B-cell lymphoma is the most common of the non-Hodgkin lymphoma types. It is very aggressive and, without treatment, most people’s survival rate is only one year.

We are also going to talk about follicular lymphoma. There is some overlap, but follicular is an indolent lymphoma. People may present or be asymptomatic. It can progress rapidly or it can last for years. DLBCL and follicular lymphoma are managed differently.

First, we’re going to talk about diffuse large B-cell lymphoma. Dr. Favaro, what are the current treatment options for diffuse large B-cell lymphoma when a patient is first diagnosed? What you do with your patients?

New Treatment Options for Non-Hodgkin Lymphoma
Current Treatment Options for DLBCL

Dr. Favaro: Before I talk about this disease, try to imagine a cancer cell as a ball. It’s a little simplistic, but if you think about a ball, in the middle of the ball is where all the DNA is. The DNA is the recipe for what makes a cancer cell what it is. There are 30,000 genes. This DNA in the middle of that cell is making all these proteins that make that cancer cell grow and make it do what it does in your body.

On the inside part of that ball are all these proteins. We’re going to talk about some of these proteins. These proteins circulate around the inside of that cell and make the cancer cell grow.

On the outside of that ball are spikes. There are different types of spikes on the outside of the cell. They’re called receptors. We can use those spikes and target cancer cells with our treatments.

New Treatment Options for Non-Hodgkin Lymphoma
CHOP

Dr. Favaro: The initial treatment for lymphoma goes back to 1976 when a combination of different chemotherapy drugs was first approved. CHOP is a combination of three different chemotherapy drugs (cyclophosphamide, doxorubicin hydrochloride, and vincristine sulfate) along with prednisone. Back in the 1970s, we were giving chemotherapy that attacked and killed all these fast-growing cells. It wasn’t targeted to spikes or proteins.

R-CHOP

Dr. Favaro: About 20 years ago, we discovered rituximab, which is a targeted therapy. It’s an antibody, a Y-shaped molecule that targets CD20, which is one of the spikes on the outside of the cell. We found that this is a great advance in cancer treatment.

If we added rituximab to all that chemotherapy, patients did better. They lived longer and had a much better chance of going into remission. R-CHOP has been the standard first-line treatment for diffuse large B-cell lymphoma for over the last 20 years.

pola-R-CHP

Dr. Favaro: Finally now, we have a new drug called polatuzumab vedotin, another targeted treatment and Y-shaped molecule. This time, it binds to CD79.

Polatuzumab vedotin added to rituximab, which hits CD20, and two different chemotherapy drugs plus prednisone (pola-R-CHP) is the new standard of care for the treatment of diffuse large B-cell lymphoma. Studies have shown that the response rate and survival is about the same versus the old regimen, but it looks like at two years, the remission rate is better if you take the new regimen of pola-R-CHP. This is the newest treatment for this disease.

New Treatment Options for Non-Hodgkin Lymphoma
Treatment Options for Relapsed Patients

Robyn: Unfortunately, even with these advances and the durable remission rate of 80% or so with the current therapy, there’s 20% where it doesn’t work. Patients will relapse very quickly. Dr. Ghosh, what happens in these patients whose initial therapy fails? What do we have to offer them now?

Autologous Stem Cell Transplant

Dr. Ghosh: In the past, the standard for patients who are eligible for an autologous transplant would be to get salvage chemotherapy, like RICE (rituximab, ifosfamide, carboplatin, and etoposide), R-DHAP (rituximab, cisplatin, cytarabine or cytosine arabinoside, and dexamethasone), or R-GDP (rituximab, gemcitabine, dexamethasone, and cisplatin).

If they are chemosensitive, meaning the tumor shrunk with chemotherapy, then they would go for an autologous stem cell transplant, which is high-dose chemotherapy followed by giving them their own stem cells back.

CAR T-cell Therapy

Dr. Ghosh: As immunotherapy advanced and as we learned more about ways to harness the immune system to fight against cancers, this was applied to diffuse large B-cell lymphoma and a novel treatment came about: CAR T-cell therapy.

Initially, it was approved after two prior lines of therapy. Patients would have had to gone through a transplant and if the transplant failed, they would get CAR T-cell therapy, or if they got chemo and then got CAR T-cell therapy as the third-line treatment. But then knowing that it was very powerful even in the third-line setting, there were some randomized clinical trials directly comparing it with transplant.

In the second-line setting, we are thinking a lot in terms of CAR T-cell therapy, reserving transplant for patients who relapsed late but are transplant candidates.

Dr. Nilanjan Ghosh

There were three large, randomized phase 3 studies that compared efficacy and toxicity of CAR T-cell therapy with that of autologous transplant. Two of those trials were positive in terms of ensuring that the primary endpoint, which was free of disease, progression-free, or event-free survival, was better compared to transplant. One of those studies actually showed overall survival was also better compared to transplant.

The current standard of care if somebody was refractory to front-line chemotherapies, like R-CHOP, pola-R-CHP, or R-EPOCH, or if they have relapsed within one year, the second-line therapy would be CAR T-cell therapy.

One of the CAR T-cell therapies called liso-cel was also used for patients who were not eligible for transplant, like older patients. Patients could get liso-cel as a second-line therapy if they had late relapse but were not considered to be transplant candidates, like if they had some organ dysfunction which would preclude them from getting a transplant.

In the second-line setting, we are thinking a lot in terms of CAR T-cell therapy, reserving transplant for patients who relapsed late but are transplant candidates. They could get salvage chemotherapy. If chemosensitive, go for transplant; if not, then still go for CAR T-cell therapy.

New Treatment Options for Non-Hodgkin Lymphoma

Follicular Lymphoma

Current Treatment Options for Follicular Lymphoma

Robyn: Follicular lymphoma is actually very common. It’s managed in the outpatient setting and Dr. Bano has seen quite a few of these cases. How do you manage these patients in your clinic?

Dr. Bano: I agree, it’s very common to see follicular lymphoma. It’s a different kind of disease process compared to DLBCL in the ways that patients present. It’s not the typical storm of symptoms that you expect with DLBCL. Follicular lymphoma tends to be slower-growing and presents in a way where most patients are even asymptomatic on initial presentation. They’ll have scans for something else, we’ll find enlarged lymph nodes, they’ll have biopsies, and that’s how we find it a lot of the time.

The way to approach treatment is a little bit different when you compare it to a more aggressive lymphoma like DLBCL. Sometimes, we’re thinking about stages like we generally do with lymphoma. The treatment differs based on what stage you are.

If you have a localized group of lymph nodes that are involved, a lot of times, if patients are asymptomatic, we watch and wait. Sometimes, if they have symptoms from a bulky lymph node enlargement, they can get radiation. A lot of times, we’ll combine that with CD20 monoclonal antibodies, as Dr. Favaro very nicely explained, that target these lymphoma cells directly. That is usually the option in limited stages of disease, like stage 1 and stage 2.

As we approach further spread out disease like stage 3 or stage 4, a lot of folks are asymptomatic and have a low burden of disease. We tend to watch and wait. That’s still an option.

Because of the indolent nature of follicular lymphoma, there’s a chance that it may come back, but we try to treat it and keep it in under control for as long as possible with milder therapies.

Dr. Kulsum Bano

Broadly, follicular lymphoma also is divided based on its grade. Not all follicular lymphoma comes equally. Some of the cases are lower grade, meaning the cells that are involved are not as actively dividing and do not appear as aggressive. For those patients, we tend to steer more toward the watch and wait and low tempo of therapy.

The more aggressive varieties, like the grade 3s, which is divided into 3A and 3B, we look more toward the DLBCL kind of treatment because these tend to act like a more aggressive lymphoma. In that scenario, we look more at chemotherapy plus immunotherapy, like R-CHOP. That usually tends to be the front line of therapy for follicular lymphoma.

It’s very varied. It’s a broad spectrum depending on stage as well as grade, but it tends to be a slow-growing disease in general. For those who get front-line treatment, some get even rituximab with bendamustine. Not everyone needs multi-agent chemotherapy.

A lot of times, we do a finite amount of chemo and follow it up with rituximab maintenance for up to two years. Every eight weeks, they get a rituximab infusion and that keeps patients in remission for a long, long time.

But as we talk about the difference in the nature of the two diseases, follicular versus DLBCL, there is also a difference in the treatment goals for these diseases. DLBCL is more aggressive and, as we were discussing earlier, we talk about a curative approach. Because of the indolent nature of follicular lymphoma, there’s a chance that it may come back, but we try to treat it and keep it in under control for as long as possible with milder therapies.

New Treatment Options for Non-Hodgkin Lymphoma
Treatment Options for Transformed Follicular Lymphoma (tFL)

Robyn: As a radiologist, there are a lot of CT scans and PET/CT involved where you monitor the lymph nodes. Unfortunately, even when someone’s in remission for two years, even after 10 years, it can come back aggressively. Dr. Ghosh, what do you do with a follicular lymphoma that is aggressive, has failed all treatments, and has transformed into diffuse large B-cell?

Dr. Ghosh: The first thing to think about when follicular lymphoma comes back is when it comes back. If it comes back within two years of front-line chemo-immunotherapy, then it’s considered to be progression of disease in 24 (POD24). Even if it has come back as follicular lymphoma, it’s a more aggressive variant. In long-term studies, the survival for that type has not been good. Many research studies have focused on this POD24 group to see what treatments would be effective.

The second thing to think about is: what does it come back as? As we discussed, follicular lymphoma can come back as low-grade follicular lymphoma, so grade 1, grade 2, or grade 3A.

Robyn: That’s based on pathology or the way it looks under a microscope.

If it’s aggressive B-cell lymphoma, then the treatment would be more like DLBCL. If it’s low-grade follicular lymphoma, you would treat more like the low grades.

Dr. Nilanjan Ghosh

Dr. Ghosh: When it comes back, it’s important to get a PET/CT scan and try to biopsy the most aggressive lymph node. A person might have multiple lymph nodes and if you only biopsy one, it could be low-grade follicular lymphoma. You don’t want to miss another lymph node with a high grade because the treatment would differ.

Convenience is important and sometimes a very bright lymph node may be in an inaccessible site, which makes it challenging. Try to biopsy the most active lymph node. If it’s aggressive B-cell lymphoma, then the treatment would be more like DLBCL. If it’s low-grade follicular lymphoma, you would treat more like the low grades.

PET scans are good, but the biopsy is where the money is, so put it under the microscope. Let the pathologist tell us what it looks like and then we can decide what to do.

In general, if it is follicular lymphoma, there are many treatment options in the second-line setting. Our commonly used one, if rituximab plus chemotherapy has been used before, is a lenalidomide-based treatment in combination with a monoclonal antibody like rituximab or obinutuzumab.

Subsequently, CAR T-cell therapy has been very effective in follicular lymphoma. Bispecific antibodies are also approved and very effective in follicular lymphoma.

In follicular lymphoma, the disease can relapse 10 or 12 years later… CAR T-cell therapy has not been around for that long.

Dr. Nilanjan Ghosh
CAR T-cell Therapy for Follicular Lymphoma

Robyn: Follicular lymphoma traditionally has been viewed as incurable. But with CAR T-cell therapy, there is now possibility of a cure. Is that correct?

Dr. Ghosh: Yes, there is a possibility. The only long-term follow ups we have with follicular lymphoma being curative is allogeneic transplant, which have been around for decades. Follicular lymphoma can come back. DLBCL typically doesn’t have late relapses. There can be some, but usually relapses occur early. In follicular lymphoma, the disease can relapse 10 or 12 years later. What that implies is that you would have to follow people for more than a decade or perhaps even two decades to be sure that the disease doesn’t come back.

CAR T-cell therapy has not been around for that long, so we don’t know for sure, but there are hints though. We now have data that patients who were POD24 (patients who had front-line chemotherapy and their disease came back within 24 months) got CAR T-cell therapy and their disease hasn’t come back even beyond two years, which means the second-line treatment was more effective than the front-line treatment. This typically doesn’t happen in cancer. If that is there, then you’re overcoming the bad disease biology.

If it doesn’t come back after 5 years, after 10 years, and after 15 years, with follicular lymphoma, that’s when we’ll know. With DLBCL, you can have quicker readouts because if it doesn’t come back in two, three, or five years, then you’re likely cured.

Robyn: We have a CAR T-cell therapy online support group and we have several patients who had follicular lymphoma and who are 4-5 five years out from CAR T-cell therapy and in remission, so it’s very encouraging.

New Treatment Options for Non-Hodgkin Lymphoma

Bispecific Antibodies

Robyn: Moving on to exciting new treatments, Dr. Favaro, would you talk about bispecifics? What’s been approved and how do they work?

Dr. Favaro: Bispecifics are a fascinating field of medicine. The first bispecific that was approved was blinatumomab, which was approved for acute lymphocytic leukemia (ALL).

It’s a very small, V-shaped molecule. One part of the V would attach to your T cell, the other part of the V would attach to your cancer cell, and it will bring them together so the T cell can kill the cancer cell. If you flood your body with these, you can bring all the cancer cells next to your T cells and get a lot of death of the cancer cells.

We still use it for acute lymphoblastic leukemia. The problem with that molecule is that it has a very short half-life. It’s a small molecule and it would be degraded quickly, so you have to use continuous infusion and treatments in the hospital.

Over the last few years, they’ve developed better molecules that are more stable. Instead of a V shape, it’s actually a Y shape. The long part of the Y stabilizes that protein so it doesn’t degrade so quickly. These Y-shaped proteins still do the same thing, bringing the cancer cell next to the T cells, and they are now available for patients with lymphoma.

Epcoritamab

Dr. Favaro: There are two that are approved for diffuse large B-cell lymphoma patients who have had at least two prior treatments. One is called epcoritamab (EPKINLY). It’s a subcutaneously administered drug that attaches to the T cell and the cancer cell, bringing them together.

They’re seeing very high response rates in the 60% range and almost 80% in some cases, where for 80% of the patients that take this drug, their lymphoma shrinks down and up to 60% will have a complete response where their lymphoma completely goes away.

It’s a great new treatment. However, when you do this, you get a lot of release of cytokines and proteins in the body and they can cause side effects, almost like you have the flu or a fever, and can even get worse. Sometimes, you can have low blood pressure. We have to be very careful about how we dose these treatments.

We start with a low dose once a week and gradually bring the dose up. The side effects usually happen in the first month or so. Once you get to the higher dose level, then you’re basically taking an injection once a month.

Glofitamab

Dr. Favaro: There’s another drug called glofitamab. It’s a very similar molecule that does the very same thing, except it’s given intravenously. We step up the dose of the treatment over a period of a month and then the patient gets IV therapy every three weeks. It’s a limited duration of treatment. For that particular drug, it’s about 12 cycles or eight months of therapy.

The results we’re seeing with these two drugs are that most patients will have a complete response and you can see that being a long, durable, complete response.

Mosunetuzumab

Dr. Favaro: There’s also a BiTE (bispecific T-cell engager) therapy that’s approved for follicular lymphoma as well. This is a drug called mosunetuzumab and is given intravenously in a similar step-up dosage. This is given for a total of either eight cycles if you go into complete response or 17 cycles if you have partial response. We’re seeing great results with that as well in patients who have had at least two prior treatments for either diffuse large B-cell lymphoma or follicular lymphoma.

Robyn: Is this performed as an outpatient?

Dr. Favaro: It’s outpatient. There’s a risk of a severe reaction. In the early onset of the trials, most patients had to be admitted in the hospital after their second treatment or so because when you step the dose up, that’s when these side effects can happen.

The other two drugs can be given completely in the outpatient setting. We have a protocol set up for epcoritamab. You take the injection once a week for the step-up dose of that first month. As the dose is increased, you get steroids before getting the treatment and for three days afterwards. That seems to really reduce the side effects.

There’s a whole lot of education and prevention that goes into preventing and treating side effects immediately.

Dr. Justin Favaro
Side Effects of Bispecific Antibodies

Dr. Favaro: You have to understand these side effects and how to manage them, so we do a lot of education for our patients. Again, most of these side effects happen within the first month.

CRS (Cytokine Release Syndrome)

Dr. Favaro: There are three major side effects of those treatments. One is called CRS (cytokine release syndrome) and that’s where a lot of cytokines are released as the dose is increased. There are certain stages. CRS can manifest as a fever or if it gets worse, you can get low blood pressure and sometimes have to be admitted to the hospital.

We give steroids and, when needed, a drug called tocilizumab. Almost always, we’re able to reverse those side effects, but it’s something we do educate patients about and keep a close eye on.

ICANS (Immune Effector Cell-Associated Neurotoxicity Syndrome)

Dr. Favaro: The second side effect, which is much less common, is called ICANS (immune effector cell-associated neurotoxicity syndrome). You can have neurologic changes, difficulty with thinking or decreased mentation, and some weakness of the muscles. Again, this is very rare, but it’s all about education, watching for that, and treating appropriately.

Infection

Dr. Favaro: The third big one is infection. We do treat with prophylactic antibiotics to prevent infection and sometimes we give IVIG to boost the patient’s immune system if needed.

There’s a whole lot of education and prevention that goes into preventing and treating side effects immediately. It’s amazing to have these drugs as options now for our patients.

With glofitamab and epcoritamab, as more time goes, we are starting to see a flattening of the curve for some patients… we’ll know over time how that looks, but it’s remarkable progress.

Dr. Nilanjan Ghosh
Success Rate of Bispecific Antibodies

Robyn: Dr. Ghosh, what bispecifics are you using and what kind of success have you seen?

Dr. Ghosh: We have all the bispecifics that are approved as well as those in clinical trials. We’ve been using mosunetuzumab for follicular lymphoma and glofitamab and epcoritamab for DLBCL.

For DLBCL, we usually do CAR T-cell therapy as second line. Studies have shown that even if CAR T-cell therapy has failed, patients have a very good response with both epcoritamab and glofitamab. These were phase 2 studies and remarkably had the same complete response rate. Epcoritamab showed about a 40% complete response rate and glofitamab also had a similar complete response rate.

Epcoritamab is subcutaneous, glofitamab is IV. Epcoritamab is given indefinitely until progression or if someone has bad side effects so they stop. Glofitamab, as Dr. Favaro mentioned, is given for 12 cycles.

I wouldn’t say choosing between the two can be tricky. Both have very similar efficacy, but you have to decide which one is going to work for somebody who lives far away and who wants limited-duration therapy.

Rather than focusing on the differences, the 40% complete response rate is the most important thing to take home. CAR T-cell therapy failed many of these patients. We don’t have very long-term data for the high-risk population in these studies who were refractory to previous treatments and yet did well.

With glofitamab and epcoritamab, as more time goes, we are starting to see a flattening of the curve for some patients. There are patients who got complete remission. They may still relapse, but there are some patients who will get into longer remission. We don’t have five-year data from either of the two, so we’ll know over time how that looks, but it’s remarkable progress.

In general, mosunetuzumab has lesser CRS compared to glofitamab and epcoritamab, but is also used more commonly in follicular lymphoma. Again, all these are done in the outpatient setting.

We have been involved in clinical trials combining mosunetuzumab and polatuzumab. A very effective strategy and though not yet approved, many other studies are ongoing.

The other thing we’ve done is combined bispecific antibodies with front-line treatment. We did a clinical trial of taking glofitamab and R-CHOP in the front line and we’ve seen remarkable remission rates.

Robyn: 80%?

Dr. Ghosh: Higher. When you combine glofitamab with R-CHOP in the front-line setting, the complete response rates are in the 80%. In DLBCL, we focus more on complete responses. Partial responses are okay to mention, but they are very temporary, so we want to focus on complete responses. Sometimes a partial response may turn into a complete response.

New Treatment Options for Non-Hodgkin Lymphoma
Clinical Trials of Bispecific Antibodies

Robyn: There are so many new exciting therapies and our panel has submitted some trials for bispecifics that they’re particularly excited about. What are some of these new trials that are revolutionizing treatment for lymphoma?

EPCORE DLBCL-3

Dr. Ghosh: The EPCORE DLBCL-3 clinical trial is looking at patients who are in the front-line setting and are not eligible for anthracycline-based treatments. They would get either epcoritamab or epcoritamab plus lenalidomide. If somebody has congestive heart failure or some cardiac problems that will preclude them from getting anthracycline-based chemotherapy, then instead of doing R-mini-CHOP or R-CHOP, they could get onto this study.

If bispecifics are moved up from more advanced relapsed/refractory treatments to earlier, can we get chemo-free front-line treatments? That is an effort with the EPCORE DLBCL-3 study.

EPCORE NHL-5

Dr. Ghosh: The EPCORE NHL-5 clinical trial is looking at epcoritamab plus lenalidomide in relapsed/refractory DLBCL. It has shown remarkable activity. It has not been directly compared with epcoritamab alone in the same study, but we have results from epcoritamab alone and that is a complete response rate of 40%. With epcoritamab plus lenalidomide, I believe the complete response rate goes up to the 50s and close to 60%.

Lenalidomide is an immunomodulatory drug. Combining an immunomodulatory drug with an antibody, which is also a kind of immunotherapy, we’re trying to focus on harnessing the immune system to fight against the lymphoma.

Glofitamab + Pola-R-CHP

Dr. Ghosh: Another powerful combination is glofitamab plus polatuzumab-R-CHP. As Dr. Favaro mentioned, pola-R-CHP showed improvement over R-CHOP. That has become a new standard. It showed improvement in progression-free survival compared to R-CHOP. If that is the backbone, can we further improve on that? That’s how we have made improvements over time.

CHOP came in the 70s. R-CHOP was approved in 2006 and showed improvement over CHOP. Pola-R-CHP showed improvement over R-CHOP. If we add a bispecific antibody to pola-R-CHP, can it show improvement over pola-R-CHP?

Glofitamab and pola-R-CHP is a study which we have done at the Levine Cancer Institute as well and it’s been done worldwide and has shown amazing effects. I saw one of my patients very recently who was in this study. He had an extremely explosive DLBCL about two years ago and he’s still in remission.

There are a lot of trials for diffuse large B-cell lymphoma that are moving a little bit more away from chemo and going toward these targeted therapies.

Dr. Justin Favaro
Glofitamab + Polatuzumab

Dr. Ghosh: Glofitamab and polatuzumab is another ongoing study. Taking polatuzumab, a CD79b antibody drug conjugate, and combining it with glofitamab showed high complete response rates. Similar studies have been done for mosunetuzumab plus polatuzumab as well.

A lot of these combinations are being done with the common theme being chemo-free. Some have chemo. CHP is chemo and antibody-drug conjugates are also chemo, but antibody-drug conjugates are very targeted chemo. It targets only the cells where the antibody binds to those spikes, so there is much less collateral damage.

The focus is trying to do less in terms of lowering the side effects, improving the efficacy, and improving quality of life and quantity of life. When you put that all together, the field is moving very well toward immunotherapies. I think these are all really good clinical trials.

Robyn: It’s very exciting. For the audience, the most common used anthracycline is doxorubicin, which is also known as the Red Devil. It can cause cardiotoxicity even in young people, who can end up with congestive heart failure at a young age. Other medications used, like cyclophosphamide, can cause neuropathy, which in some cases is irreversible. To move away from these medications and have the same results or better is great for quality of life and very, very encouraging.

Dr. Favaro: These are all great trials. There are a lot of trials for diffuse large B-cell lymphoma that are moving a little bit more away from chemo and going toward these targeted therapies.

Zanubrutinib + Tafasitamab + Lenalidomide + Rituximab

Dr. Favaro: There’s another interesting trial combining four different drugs and none of them are really chemotherapy. There’s an oral drug that’s a BTK inhibitor called zanubrutinib, another monoclonal antibody called tafasitamab (MONJUVI), plus lenalidomide and rituximab. Of the four different drugs, two of them are targeting the spikes, one of them is targeting a protein inside the cell, and the lenalidomide is there to stimulate the immune system, the T cells, to grow and attack the cancer.

A newly diagnosed patient with no prior chemotherapy is seeing a very nice response rate. In this particular trial, they started with this and if they went into a complete response, then they got two cycles of chemotherapy and went back on the targeted therapy.

I like the idea of targeting some of these molecules on the outside or the inside, combining it with something that turns the immune system on as a way to eliminate some of those long-term potential side effects from chemotherapy. I think that’s the theme that we’re seeing here.

Robyn: I’m one of the first patients to get CAR T-cell therapy. I’m going to have the experts explain it, but as a patient, I compare it to Pac-Man. You put the T cells in and the little Pac-Man goes over and eats the cancer cells.

CAR T-cell therapy is new. I received tisagenlecleucel in 2016 as a phase 2 trial. It’s been very successful for me and I’m very, very grateful. I was able to go back to work as a physician. I have a great quality of life. Most of my side effects are from the chemotherapy, which did save my life but I wish I hadn’t had those.

This is a great therapy and now, not only is CAR T-cell therapy used for blood cancers, but it’s also being used in trials for solid tumors and autoimmune diseases, such as lupus, scleroderma, and glioblastoma.

Dr. Favaro, can you explain CAR T-cell therapy?

Dr. Favaro: T cells are part of your white blood cells that circulate around your body. They’re constantly looking to treat infection or try to treat cancer and that’s part of their job. Why can’t they kill cancer cells on their own? Because cancer cells learn how to hide. There are certain proteins they can take away from their surface, so your normal T cells can’t find the cancer cells sometimes and that’s part of the reason why cancer cells can grow in your body.

How do we stimulate those T cells and make them angrier and more attracted to kill and attack those cancer cells? In my mind, that’s what CAR T-cell therapy is.

The whole process starts by taking out your T cells. We do that as a part of an apheresis process that happens in the clinic or in the hospital. Those T cells are sent off to a company that will take those T cells and reengineer them in the lab to become CAR T cells. Those T cells that are now transformed will attach to a CD19 spike on a lymphoma cell.

The whole process takes about two weeks. The CAR T cells are infused back into the body. They have this new protein on the outside of their cell called chimeric antigen receptors (CARs). They go into the body and attack the lymphoma cells. It’s pretty amazing technology.

The data shown with diffuse large B-cell is that you can get a 40% long-term remission rate in patients who have had prior treatment but now the lymphoma has come back. Those are amazing results and Robyn is a testimony to that.

The downside is it takes a long time. This is a process and you have to wait. There’s also the issue of insurance authorization. Medicare pays for these treatments, but insurance companies take a long time. You have lymphoma that’s growing in your body and we have to wait to get this whole process done.

The Latest in Multiple Myeloma - Understanding Promising Treatment Options

It requires you to take other treatments, like lymphodepleting chemotherapy, to control the lymphoma before we can get the CAR T-cell process done. Once you collect the cells, it takes about two weeks to get them back. It could take up to six weeks from the time you meet until infusion day.

There’s a lot of thought about how we can make this process better. The companies that make these products are telling us that 8 out of 10 patients who are eligible aren’t getting CAR T-cell therapy. Maybe they don’t live close to a big academic hospital center or it takes too long and their cancer is growing too quickly.

A lot of the research is focused on making the process faster. Can we create CAR T cells in the lab so we don’t have to go through this whole process? That’s what we’re looking to talk about down the road.

The goal has also been to see if we can lower the intensity and the incidence of CRS and neurologic toxicities.

Dr. Nilanjan Ghosh
Side Effects of CAR T-cell Therapy

Robyn: Dr. Ghosh, you have spearheaded CAR T-cell therapy in Charlotte, did the first cases, and have a lot of experience. I would love to have you talk about the side effects of CAR T-cell therapy.

Patients are terrified of the CRS and ICANS. Meanwhile, they’re not as terrified of a stem cell transplant, which has more side effects. How you do you manage the side effects? What kind of results have you seen with CAR T-cell therapy?

Dr. Ghosh: We have had significant experience with CAR T-cell therapy at our center because we participated in some of the clinical trials, which led to the approval of CAR T-cell therapy. It’s certainly a learning curve on how to manage CRS and ICANS.

When we think about CRS, these are serious side effects, but what’s important is these are reversible for the most part. Some clinical trials report very high rates of CRS and some even with ICANS. Most of these happen early on and within a few days of receiving CAR T-cell therapy.

They are managed with a team of physicians, nurse practitioners, nurses, and pharmacists who are very, very in tune with how to manage these side effects. We also have help from ICU doctors, neurologists, and infectious disease specialists, so it’s a team approach.

Each grade of CRS and ICANS has its own treatment. As the grade goes higher, treatments can intensify. The mortality from CRS and ICANS is extremely low. The reversibility is extremely high.

CAR T-cell therapy is underutilized because of the fear of side effects, but the potency which it has far outweighs the risks associated with it

Dr. Nilanjan Ghosh

CAR T-cell therapy has a 40% long-term remission rate and, more importantly, it’s a one-time treatment. You come in, get three days of lymphodepleting chemotherapy followed by a couple of days rest, get the CAR T cells, and then a week of monitoring for CRS or neurologic side effects. If nothing happens, then you remain outpatient. If they happen, then we treat them and reverse them, then monitor for infection risk after.

The treatments can include acetaminophen, fluids, oxygen, steroids, and other drugs, like tocilizumab and anakinra. What we have seen is by doing these measures and being aggressive in terms of treatment, these side effects are reversible.

The goal has also been to see if we can lower the intensity and the incidence of CRS and neurologic toxicities. There are drugs which can be used. For example, prophylactic steroids can sometimes lower the intensity of CRS and that has already been approved. There are multiple ways, but if you have a team who has been doing it for a while and can react immediately, the side effects can be managed.

Another side effect, which is not very common but very important to address, is macrophage activation syndrome or HLH (hemophagocytic lymphohistiocytosis). Again, that is also managed with medications. We are able to recognize it early by monitoring things like ferritin and other markers as well.

I feel that CAR T-cell therapy is underutilized because of the fear of side effects, but the potency which it has far outweighs the risks associated with it, especially now that it’s been so long and we’ve been able to manage the risks in a relatively protocolized manner.

Be aware of side effects, but don’t be freaked out by them.

Dr. Nilanjan Ghosh

Robyn: My therapy was pretty much outpatient. I think that some of the treatments are drifting toward outpatient until you actually need to be inpatient, which decreases your risk of infection and increases your quality of life. My understanding is that a lot of hospitals are trying to move toward that, but it depends on the type of CAR T and also the patient.

Dr. Ghosh: The patient and caregiver. Another very important thing for CAR T-cell therapy is you need to have a caregiver. If someone is having confusion, you need a caregiver if you’re outpatient to be able to call and say that there’s something wrong.

Even in an outpatient setting, for the initial part, there are very frequent follow-ups, almost daily, so distance from the center can be an issue. If someone lives close by, you can do it outpatient. If someone lives far, it may be hard to go back and forth. We are working very hard to try to overcome barriers to CAR T-cell therapy.

Be aware of side effects, but don’t be freaked out by them. If CAR T-cell therapy is right for you, go for CAR T-cell therapy at a place where they know how to manage these side effects and get the benefits.

New Treatment Options for Non-Hodgkin Lymphoma

Cancer Clinical Trials

Robyn: One of our co-presenters is The Leukemia & Lymphoma Society. They have a Clinical Trial Support Center with nurse navigators who can help patients look for trials because it can be overwhelming.

The first person to ask about trials would be your physician, but no matter how good the physician, they won’t know about all the trials in the United States and the world. Another resource is ClinicalTrials.gov, which is what my husband and I utilized when we were looking for a trial though it’s a little bit harder to navigate. Trials are accessible, but you have to be your own advocate to some degree.

Dr. Ghosh: For anyone who has barriers to clinical trials, remember that we would not be here today if not for clinical trials. Even CHOP came through a clinical trial, which was started in the early 70s. Everything came through clinical trials.

Robyn: Again, I’m an example. I was one of the first who got CAR T-cell therapy through a clinical trial. I’ve told other patients that sometimes, the best treatment you can receive is through a clinical trial.

Dr. Ghosh: Cancer clinical trials don’t compare a cancer drug and a placebo. They have a well-established cancer regimen and may add one drug to it, but those who are not getting the study drug get the best established cancer regimen. Unlike other diseases where you can get a placebo versus the study drug, this is a serious, life-threatening disease so you’re either getting the standard of care or the new promising drug. If it’s a phase 1 or phase 2 study, everybody gets the same treatment.

Robyn: In a lot of trials, patients have been through all these standard treatments. They may have had CAR T-cell therapy or BiTE therapy then the lymphoma comes back. What do you do? That’s where these companies are on the cutting edge of developing newer treatments.

Cancer clinical trials don’t compare a cancer drug and a placebo. They have a well-established cancer regimen and may add one drug to it, but those who are not getting the study drug get the best established cancer regimen.

Dr. Nilanjan Ghosh
TRANSCEND FL

Robyn: I know some people who are in the TRANSCEND trial for follicular lymphoma. There’s a lot of people enrolled in that. From what I’ve seen from the data from ASCO, it looks like it’s very successful.

Dr. Ghosh: TRANSCEND FL took patients with relapsed/refractory follicular lymphoma and treated them with liso-cel. It’s been reported and has fantastic efficacy with very high complete response rates in the 90s.

The follow-up is not very long, so that’s one downside, but the FDA is doing a priority review to see if this is good enough that it should get approval in follicular lymphoma. It also has been done as second-line treatment and that has very, very good activity in the second-line setting.

SWOG S2114

Dr. Ghosh: Remember we said that 40% patients with large B-cell lymphoma will get long-term remission after CAR T-cell therapy. What about the other 60%? We always have to think about the people who didn’t benefit. We have a great example of benefit right here, Robyn, but there are others who didn’t.

Complete remission is the most important thing for diffuse large B-cell lymphoma. What about people who get partial remission or stable disease and it didn’t grow? That’s not good enough because within a few months, many of those patients will progress. What if you can intervene before that with bispecific antibodies and polatuzumab?

This S2114 study is a trial which is trying to improve the outcome of patients who are in partial remission or have stable disease by adding drugs post CAR T-cell therapy and trying to see if they would benefit and convert them into complete remission. This is a national trial and we have it open at our site as well.

ELARA

Dr. Ghosh: The ELARA study is looking at tisagenlecleucel for relapsed/refractory follicular lymphoma. This is showing high response rates, low CRS, low neurotoxicity, and durable remissions. Now with three-year follow-up and showing that nearly close to 60% of patients are in remission.

This is a one-time treatment given three years ago and patients are still in remission. Many of those patients are in that POD24 group, where they had progressed within 24 months, so their first remission was two years and now the second remission has been lasting for three years. I hope the remission will last for 5, 7, 10, 15 years, but only time will tell. That’s where whether it’s curable or not will come in for follicular lymphoma.

A lot of companies are developing CAR T cells in the lab that are engineered so they can go in and attack the lymphoma cells, but the body’s immune system won’t attack them and kill them.

Dr. Justin Favaro
Other Clinical Trials

Dr. Favaro: It’s exciting to see CAR T-cell therapy patients in follicular lymphoma and seeing long-term responses. That’s a disease that tends to relapse over and over.

Robyn: People can go on with their life.

Dr. Favaro: The other trials I do like are looking at CAR T-cell therapy patients who don’t have a complete response. Let’s bring in BiTE therapy for those patients as well to try to get them into complete response.

We’re part of a national network of cancer clinics called OneOncology and some of our clinic sites are looking at doing outpatient CAR T-cell therapy. There are different products that are now approved. Liso-cel is one that has the least side effects and is the most predictable.

In outpatient clinics in the OneOncology network, we’re doing CAR T-cell therapies and watching them as an outpatient. They can be watched for four days. It’s pretty predictable that at day four is when a lot of the side effects happen for that particular product.

That’s one example of how we’re moving things more toward the outpatient by monitoring patients while they’re at home. If it’s day four and the patient is starting to have side effects, we bring them in, keep an eye on them for a few days, take care of the side effects, and send them home.

There are a lot of companies developing new CAR T-cell therapies. Why do we need to take the T cells from the patient, reengineer them, and put them back? What about taking regular cells? You can take a culture of human cells and, believe it or not, take stem cells and turn them into T cells in the lab.

A lot of companies are developing CAR T cells in the lab that are engineered so they can go in and attack the lymphoma cells, but the body’s immune system won’t attack them and kill them because these are foreign cells to the body.

One of the other trials happening in the OneOncology network is using allogeneic CAR T cells, meaning they come from a different person. They’re engineered in a way to help your body accept them and see if you can get a response.

Multiple companies are doing this and, in some cases, these are patients who have been through everything. We get a response and a reduction in their lymphoma by using these foreign cells created in a lab. To me, that’s where the future is: looking at this in the outpatient setting and having it ready for the person when they need it.

Robyn: It’s also less costly because it’s technically off the shelf, which should be excellent.

New Treatment Options for Non-Hodgkin Lymphoma

Treatment Sequencing

Robyn: At some of the meetings, people still talk about bispecifics versus CAR T-cell therapy and in which order. We talked about bispecifics after CAR T-cell therapy. Some people are saying bispecifics should be done before CAR T-cell therapy.

Dr. Ghosh: CAR T-cell therapy came first. Outside of blinatumomab, which was for ALL, most of our DLBCL and follicular bispecifics came later. Naturally, by the time bispecifics were available in trials, CAR T-cell therapy had already been around. We know that after CAR T-cell therapy, bispecifics are very active, but what we didn’t know was the reverse.

Recently, a European study was presented and showed that if you use bispecifics before CAR T-cell therapy, you can still get really good activity from CAR Ts. On that study, bispecifics failed a lot of patients so they went on to get CAR T-cell therapy, which was then effective.

In the United States, bispecifics are not approved in the second-line setting, while CAR T-cell therapy is, so undergoing CAR T-cell therapy before bispecifics makes a lot of sense. We don’t have long-term data for bispecifics in the second line but we do have data saying that if it didn’t work, at least CAR T-cell therapy may be able to rescue those patients.

That was a very good study. Overall, we do great in oncology in terms of getting new drugs approved, but we don’t do a great job in sequencing them. That’s left a lot to the physician in discussion with the patient because not everything from the menu is going to be available or accessible right away.

With disease, you may have to do something right away because you can’t wait for six weeks or so to get CAR T-cell therapy. If CAR T-cell therapy is available, then you may want to wait and do the bispecifics later.

New Treatment Options for Non-Hodgkin Lymphoma

In DLBCL right now, I would do front-line treatment of CAR T-cell therapy and bispecific antibodies. In follicular lymphoma, you could do the reverse. It’s a more indolent disease. We don’t know about curability as much. We know that mosunetuzumab works well in relapsed/refractory follicular lymphoma. You have long-term remissions and you could save exa-cel or tisa-cel and, if liso-cel does get approved, then liso-cel for later.

As we are seeing longer data, you have to think: do you want to be on a treatment where you are coming in frequently versus getting a one-time treatment? The treatment where you’re coming in frequently has lesser side effects than the one-time treatment, so it’s a discussion.

Will clinical trials ever be done to answer the sequencing question? I don’t know. I think we’ll learn over time. What will matter is the side effects and the durability of the response. Any response which is durable will be higher in the flowchart compared to the ones where relapse will happen sooner.

Folks who’ve gotten chemotherapy upfront are often left with life-limiting or daily activity-limiting side effects, like neuropathy, so it’s extremely exciting to have this option of chemo-free treatment without long-lasting side effects.

Dr. Kulsum Bano

Possibility of Chemo-Free Cancer Treatment

Robyn: I’ve been in medicine for a long time. When I trained in medicine, oncology was still relatively barbaric, I would say. Chemotherapy and cancer treatments involved cutting, burning, and poisoning. Way back in the 80s, they didn’t even have antiemetics or ports, so giving people doxorubicin was difficult to say the least.

We’ve progressed dramatically. Oncologists have found ways to decrease nausea and take care of neuropathy, but the side effects are still there. Do you see chemo-free treatment of cancer in the future? Perhaps in the next 10 to 15 years?

Dr. Bano: I think that’s the direction we’re slowly heading in. A lot of these trials are slowly moving treatments that were thought to be more exciting and more novel approaches from the fourth to the third, to the second, and then slowly into the front-line setting. That happens over time because the more we learn, the more experience we have with all of these wonderful patients who’ve been on trials and given us this knowledge.

As a community oncologist, that’s extremely exciting because I hope to see patients for years to come who are going to be disease-free and who’ll just be monitored. Folks who’ve gotten chemotherapy upfront are often left with life-limiting or daily activity-limiting side effects, like neuropathy, so it’s extremely exciting to have this option of chemo-free treatment without long-lasting side effects. People are going to live longer with these disease-free intervals. It’s very exciting and hopefully that’s where we’re headed.

Dr. Favaro: I think it’s a combination of things. If you look at chemotherapy, these are chemicals that kill fast-growing cells and that’s pretty good against lymphoma. These often are fast growing, especially diffuse large B-cell lymphoma, so it’s been very active treatments that have put people into long-term remission. But the downside of chemotherapy is the potential long-term side effects plus it’s harder to go through, so what can we do?

Cancer cells are complicated. We’ve got the DNA inside the cell, which has 30,000 genes and over 100 probable mutations in those genes. You’ve got all these crazy proteins in the cell. A lot of them are active and helping the cell grow. Then there are the different spikes outside of the cell.

You have to think about how you attack not just one protein or one spike but multiple targets. A trial I mentioned took a BTK inhibitor and attacked the protein inside and had a couple of drugs attacking the spikes on the outside. That’s probably where we’re going to head to avoid treatments that are so toxic.

Multiple targeted agents is the way to go. For example, with BiTE therapy, we know what happens with those patients. It’s very effective pretty early, but what’s going to happen down the road? Will there be a potential risk of the cancer coming back?

You’re taking the T cell, bringing it to the cancer cell, turning that T cell on, and killing the cancer cell. But over time, those T cells get tired, which is something called T-cell exhaustion, and don’t want to work as well. Sometimes it’s as simple as giving people a break from treatment to let their T cells recover.

But the other thing I think that we’re going to head toward down the road is limited duration therapy but baking something in. You give BiTE therapy, but because we know the T cells can get exhausted, we need to add in another targeted therapy to kill some of those proteins and give 2 or 3 of those for a limited duration. I hope that’s where we end up to finally wipe out the disease for good.

New Treatment Options for Non-Hodgkin Lymphoma

Improving Access to Cancer Care

Robyn: One of the things that all of us as doctors are focused on is access to care. In my case, there was no CAR T-cell therapy offered nearby. My oncologist here had to coordinate with an oncologist who was in a trial in Ohio and my team in Charlotte did a fantastic job. Dr. Ghosh, what do you do in the academic center to reach out to community doctors? How do we improve access to care?

Dr. Ghosh: Late 2017 is when we moved forward with signing up for the TRANSCEND study, which eventually led to approval. Once we signed up for the study, we were the only center in all of North and South Carolina to offer CD19 CAR T-cell therapy before any other center. We got patients from everywhere in that study.

Access is certainly a very, very big issue for CAR T-cell therapy. It becomes even bigger because you need a caregiver. How do we overcome some of the socioeconomic barriers? The caregiver would have to take some time off. Typically, we need patients to be within a one-hour radius, so they would need local housing.

The first part of access is providing education and understanding the benefits of CAR T-cell therapy and referring the patients in a timely manner. It could take up to 6 to 8 weeks to get CAR T-cell therapy, so if you wait for the referral, then it may not be doable because the disease will take off. Early referral is extremely essential for CAR T-cell therapy.

There’s a lot of fine-tuning involved, so the team together with the patient decide what’s best. We try to do this in a really timely manner.

Dr. Nilanjan Ghosh

Patient navigation can be very helpful to help find resources, whether it’s local housing or any type of support. I think that’s essential.

Insurance can be a barrier, especially in terms of single-case agreements, but we are trying very hard. We have a study in which we are looking at the effect of these insurance problems on patient outcomes, so that is a barrier we’d like to overcome. Some barriers are within our control, some are not.

There are ways to control the disease. Giving the right treatment is very important. For example, we have learned that if you give bendamustine, then that can mess up your CAR T-cell therapy. Bendamustine kills T cells, so if you kill T cells before you collect them, then those T cells aren’t going to work. Either you won’t have much or if you have enough, they may not be as functional and not be able to do the job.

What is the right treatment to use if you’re planning to do CAR T-cell therapy? There are so many available. Do you want to modify your regimen somewhere so that you can control the disease but perhaps not kill all your T cells before you collect them? Do you want to wait? But if you wait, then the disease may take off and that may not work.

There’s a lot of fine-tuning involved, so the team together with the patient decide what’s best. We try to do this in a really timely manner. We coordinate very well with all our regional sites within the Levin Cancer Institute as well as beyond.

traveler

The bigger challenge is those who live far away. Do they want to come to Charlotte to get CAR T-cell therapy or would they rather not do it because it’s not feasible to come? That’s where eventually having outpatient CAR T-cell therapy done locally comes in and having the expertise to manage the side effects if they happen.

We have more CAR T-cell therapy centers today than two years ago. I hope it keeps getting better and better so that more patients all over get access to this treatment.

We also don’t want to have the treatments in an environment where there isn’t the expertise to manage the side effects because then it becomes very hard. Somebody who came in for a potential curative disorder and perhaps were going to be cured succumbed to the side effect because the team was not able to manage them. That wouldn’t be right either.

The other part of it is coming up with protocols to lower the incidence of side effects without compromising efficacy. This is where the clinical trials of some of the products that have less CRS and less ICANS come in. Not zero, unfortunately. I don’t think we’re going to get there.

Infections can be there, but we know how to manage them. Please communicate quickly so that they can be managed appropriately.

Dr. Nilanjan Ghosh

Robyn: Zero is impossible. What if there are trials at Memorial Sloan Kettering in New York or MD Anderson in Texas? The idea is that people can follow up with their local oncologists.

Dr. Ghosh: After the CAR T-cell therapy. It’s a one-time treatment.

Robyn: That’s what happened in my case. Sometimes you have to go somewhere else for treatment or to join a trial and then do follow-up blood work and scans locally to make it more convenient for the patient.

Dr. Ghosh: The most important thing for CAR T-cell therapy is that there are two side effects that can persist after being discharged.

One thing to watch out for is low blood counts, which is an important one and can persist for a little bit of time. For the most part, that’s because of the lymphodepleting chemotherapy given prior. But sometimes, if patients have had many prior treatments, low blood counts can also be because now they’ve developed MDS (myelodysplastic syndrome) or a pre-leukemia situation.

It’s important to pay attention to the low blood counts to see if it’s getting better or persisting for a very long time, then looking at the bone marrow to see if they have developed something else because there are other reasons for low blood counts other than CAR T-cell therapy.

Second is infection risk. CAR T-cell therapy takes out the B cells because normal B cells also express CD19. You can check immunoglobulin levels and give IVIG. Vaccine responses also go down, so if someone had a vaccine for flu or COVID, they may not be able to respond well, so people become prone to infections.

Patient education is very important as well as letting your doctors know. I always advise patients that if they have a cold or something, reach out to their doctors first. Many times, we would react to it faster. We won’t give a Z pack for a cold. We’ll get them in, get a swab, check what virus is there, and check the immunoglobulin level.

Give them antivirals, if antivirals are available. Give them IVIG, if the IgG is low to help them overcome that infection. Get some imaging needed to see if there’s pneumonia. When the immune system is low and you get a virus and sit on it for some time taking an antibacterial, which is not going to work because it’s not a bacterial infection, it can get worse.

We educate our patients that infections can be there, but we know how to manage them. Please communicate quickly so that they can be managed appropriately compared to some other person who is not as immunocompromised.

New Treatment Options for Non-Hodgkin Lymphoma

Final Takeaways

Robyn: This has been a great discussion. If there’s something you would like to tell the people about diffuse large B-cell lymphoma and follicular lymphoma, treatments, and the future, what final statements would you like to give?

Dr. Favaro: There is so much to learn for patients and doctors. These new treatments come out and it’s our job to learn about them. CHOP came out in 1976. It was our job to learn how to give it and also how to manage any side effects that come up. That’s the same with CAR T-cell therapy.

Quite frankly, 4,000 papers come out every day in health care. There’s a ton of information coming out. We are constantly learning and educating patients about these new treatments.

The cooperation that we have as a community practice with academic centers is very important. When we see patients who need CAR T-cell therapy, we refer them and take them back to help manage potential side effects. The technology that’s advancing to make these treatments less toxic is key. We used to have to admit patients overnight for epcoritamab, for BiTE therapy; now we can do it all as an outpatient. That’s the type of thing that’s happening on a daily basis.

Physicians will never go away. We are here because we know you. We take care of you as a person, but we are going to see more and more about artificial intelligence coming into health care. It’s happening. We do need to look at that and embrace that.

Somebody comes in with lymphoma. What should their treatment be? There are so many different factors: age, personal health, disease, potential treatments, and side effects. It takes a good physician to understand the data. But over time, there probably will be the development of assistance to doctors with artificial intelligence and neural networks that I think will help. There are journals about AI in oncology and I think this is going to be the future for health care as well.

Dr. Bano: None of us in medicine work in a vacuum. It’s a concerted effort getting these patients to the most advanced treatments out there. In the community, our responsibility is to know that these even exist and to maintain that chain of communication with the academic centers to get our patients the care that they need, but we always serve as home base. We give patients the feeling that, yes, we’re sending you away, but you’re always going to come back and we are here to take care of you for years to come.

It’s always been a great collaboration between community and academics, getting that relationship established, and always having that chain of communication to ask questions and get opinions. It doesn’t always have to be advanced therapy. Sometimes you get a challenging case that you want to discuss with someone who has seen something like this before.

It’s very exciting to see what’s on the horizon. It’s exciting to see what we can do for our patients. It’s a learning process. Every day, we learn something new.

In the community, our responsibility is to know that these even exist and to maintain that chain of communication with the academic centers to get our patients the care that they need, but we always serve as home base.

Dr. Kulsum Bano

Dr. Ghosh: I cherish the community-academic partnership. I’ve cherished that over the years. That helps patients to get their treatment locally but also get access to a specialist who treats that disease. When I started, lymphoma treatments were not as effective but were simple. You get the first line, another option for the second line, then after that, there were 1 or 2 options and that’s it.

Now, there are a lot of options. When you have so many options, each with their unique side effects and sequencing is not worked out, how do you know which is best for you? There are so many intricacies. If you use this, then the next treatment could be a problem.

Trying to find the right option, keeping abreast of what comes out, and keeping pace with how this is moving along can be challenging. That’s where the academic-community collaboration can be very good. Patients can always go back to the community to get their treatments, have access to a new clinical trial or the latest treatment, and have really good care.

I encourage participation in clinical trials, knowing that these are ethical and vetted by institutional review boards. That is how we have come to where we are and I hope that we get into more chemo-free treatment options.

Some chemo is still very effective. I would not say anthracyclines have saved many lives. They have been around for 50 years, but if we can achieve our goal with less toxicity and by harnessing the immune system, that would be fantastic.

Robyn: I’m honored to be here. Shout out to The Patient Story and the unique ability of patients to get their voice out and for people to do their research online. As a physician and a former patient, it’s very important to be your own advocate, to research, to ask questions, and to keep your mind open. Sometimes clinical trials are the best treatment, so do consider them.

Consult with your doctor. It’s okay to get a second opinion at some points. Medicine has come a long way. When I first started, there was not much available. The survival rate for non-Hodgkin’s was about 30-40%.

I hope that everyone gets treatment and gets in remission like myself. At that point, you need to live your life. Enjoy your family, travel, work, stay healthy, and exercise. Don’t let cancer define you. It’s part of you, but there’s much more to you, so enjoy life.

You need to be your own advocate. If you feel like something that’s been recommended is not working for you, you have all the right to get a second opinion.

Dr. Kulsum Bano

Q&A

Getting a Second Opinion

Robyn: Joan asks, “What is the polite way to get a second opinion without being rude?”

Dr. Bano: Very rarely are there egos in medicine. As a physician, you try to make the best decision for your patient knowing that there may be something out there that is newer or better. Everyone is entitled to a second opinion and that’s how we learn more.

If somebody comes back to me with a different treatment approach and says somebody else recommended this, that’s something I would definitely encourage. You need to be your own advocate. If you feel like something that’s been recommended is not working for you, you have all the right to get a second opinion. You’re not being rude at all. You’re entitled to that and it’s actually encouraged if that’s what you feel is right for you.

Robyn: I agree. Even in radiology, we get asked for second opinions all the time. Doctors are human. We are not perfect. We can look at the same case and have different opinions. We’re not insulted. We’ve all been trained to work together and I would say that happens 99% of the time. There are always exceptions.

If you look at the commonly used CAR T-cell therapy, the complete response rate is much higher than the complete response rate for epcoritamab.

Dr. Nilanjan Ghosh
Epcoritamab vs. CAR T-cell Therapy

Robyn: Don asks, “I’m on epcoritamab. We considered CAR T-cell therapy, but wouldn’t be able to provide the 24/7 care required. So far, it’s working very well. How does it stack up compared to CAR T-cell therapy?”

Dr. Ghosh: They have never been compared head to head, so there is currently no clinical trial which takes half the patients and gives them epcoritamab and half the patients get CAR T-cell therapy. The best way to compare two groups of patients is if they were randomized on a clinical trial, had similar characteristics, and then followed over time to find out the effectiveness of one versus the other.

If not, you’re comparing across trials and when you do, it’s flawed because the patients who went for epcoritamab may have very different characteristics than the patients who went for CAR T-cell therapy. In fact, many patients who went for epcoritamab on a clinical trial already had CAR T-cell therapy, so how could you compare the effect of CAR T-cell therapy with a drug used for post-CAR T-cell therapy failures?

Having said that, we are left with no choice but to compare across trials. I will say that if you look at the commonly used CAR T-cell therapy, the complete response rate is much higher than the complete response rate for epcoritamab. Epcoritamab is around 40%. CAR T-cell therapy complete response rates are usually in the 50s to 60s.

That being said, it comes down to the 40% number because even if CAR T-cell therapy gets a higher complete response, some people will start relapsing despite getting a complete response. We know that with CAR T-cell therapy, about 35 to 40% people will have long-term remission.

We don’t have long-term data yet with epcoritamab. The complete response rate is 40%, but some of those will progress over time. We don’t know whether it will go down to 30% or 25% as we go up to five years, but we will find out over time.

At this point in time for DLBCL, we feel that CAR T-cell therapy is better, but if it’s not feasible, bispecific antibodies would be the next best option. The important thing is: are you getting complete remission or not? If it’s complete remission, we see long-term sustainability. If it’s not complete remission, then we start seeing early progression.

Epcoritamab is targeting CD20 and CAR T-cell therapy is targeting CD19 — two very different ways of attacking the lymphoma. CAR T-cell therapy is still a great option for those who choose epcoritamab for whatever reason.

Dr. Justin Favaro

Dr. Favaro: Another point is that a lot of patients on the epcoritamab trial had CAR T-cell therapy before. If you have somebody who’s never had CAR T-cell therapy and you had the option of CAR T-cell therapy or BiTE therapy, which one do you choose if you’re eligible for both?

It comes down to logistics and what’s going to be a good fit for you. Keep in mind that if you would need CAR T-cell therapy later, you can still get it because a study at ASH 2023 showed that if even if you had BiTE therapy before, you’re still eligible to get CAR T-cell therapy later.

Epcoritamab is targeting CD20 and CAR T-cell therapy is targeting CD19 — two very different ways of attacking the lymphoma. CAR T-cell therapy is still a great option for those who choose epcoritamab for whatever reason. You can still have a great outcome. It doesn’t necessarily matter how you sequence it.

The hope is that whatever treatment you’re getting works for you and you won’t need anything else. But if you do, there are options available and there will be even better treatments in a few years.

Dr. Nilanjan Ghosh

Robyn: If for some reason this doesn’t work and you decide to get CAR T-cell therapy, a lot of the hospitals have come a long way with helping people get 24/7 care. There are options. Hopefully you won’t need them since epcoritamab is working well, but know that there are things that the hospitals are now aware of and they’re trying to assist patients with those.

Dr. Ghosh: There are many devices coming out for 24/7 monitoring, especially in the outpatient setting. Companies are coming up with devices to monitor your oxygen level, heart rate, and temperature then feed them back to the electronic medical record and create alerts. At least from the standpoint of vital sign monitoring, people are trying to overcome this barrier.

Understand that 24/7 support, even if it is for a short time, is a lot for a caregiver, especially if the caregiver has to work. You can rotate caregivers. You don’t need to have just one. Most places will allow multiple caregivers.

Epcoritamab is a good option if you’re not able to do CAR T-cell therapy. You can still have very long remission and perhaps not need further treatment ever again. The hope is that whatever treatment you’re getting works for you and you won’t need anything else. But if you do, there are options available and there will be even better treatments in a few years. Maybe allogeneic CAR Ts will hit a big wave. We don’t know yet, but we’ll find out.

Dr. Favaro: That’s the advantage of getting BiTE therapy upfront. If you need something later, it may be a lot easier with a lot fewer side effects and it can be done as an outpatient. With epcoritamab, you can get steroids and don’t need to be in the hospital. As we make more progress with CAR T-cell therapy, maybe we can do that as an outpatient to reduce severe side effects. Sometimes there’s an advantage to waiting as the technology advances.

Dr. Ghosh: If it’s accessible, knowing the track record of CAR T-cell therapy and that now we have five-year data, we still like to sequence CAR T-cell therapy before bispecific antibodies. Over time, we’ll find out if things change and do it in reverse.

Remission After Bendamustine & Rituximab (BR)

Robyn: Diana asks, “What is the median length of remission after the first B&R treatment”

Dr. Ghosh: For which disease?

Robyn: I would assume it’s follicular lymphoma, but we don’t know what stage. Let’s assume it’s stage 2.

Dr. Bano: If it’s stage 2 follicular lymphoma, generally you have a sustained response after B&R treatment. We’re looking at about five years or so. We need more information to answer that question appropriately.

Dr. Ghosh: It may also depend on whether rituximab maintenance was used. It could be a little bit different with maintenance versus without. I’ve even seen patients who are 10 years out after bendamustine and have not relapsed. Some people will relapse, so it’s a whole spectrum.

There are treatments now that will attack both follicular lymphoma and the transformed lymphoma, so sometimes you want to harness that.

Dr. Nilanjan Ghosh
Possibility of a Repeat Transformed Follicular Lymphoma (tFL)

Robyn: “If you have follicular lymphoma that transformed into diffuse large B-cell, went into remission after treatment, but a few years later, the follicular lymphoma came back, what is the probability that this will transform again?”

Dr. Ghosh: With indolent follicular lymphoma, there’s a small percentage of transforming every year. As more years go by, that risk accumulates. If it’s already happened, will a second transformation happen? It’s possible, but the likelihood goes down because it’s a random event.

Is it a relapse of the previously transformed follicular lymphoma? That’s hard to sort out, but usually what happens with the transformed disease, if the transformed disease has been in remission for a long time, that’s an aggressive lymphoma and usually, aggressive transformers respond well to whatever the treatments were given to them, especially since long-term remission was achieved.

The likelihood of what comes back is often the indolent lymphoma and we see this sometimes with transplant. I had a patient who had follicular lymphoma, had treatment, had a relapse of the follicular lymphoma, had another treatment, then her lymphoma transformed, and we gave her transplant for that. Years later, the aggressive transformed lymphoma went away and she had a relapse again, but this time, it was back to follicular. The aggressive lymphoma never came back. What we did at the time was CAR T-cell therapy for the follicular lymphoma.

There are treatments now that will attack both follicular lymphoma and the transformed lymphoma, so sometimes you want to harness that. For example, axi-cel is approved for follicular lymphoma and for DLBCL. When you use a treatment like CAR T-cell therapy, you are basically killing both. Ultimately, it’s all coming from one B cell. It may be transformed, but if you attack that B cell clone, then both the low-grade and the high-grade can go away. Similar with bispecific antibodies. They attack both. Many of the treatments we use now, especially some of the more modern treatments, have activity against both follicular lymphoma as well as the transformed component.

The fortunate part about lymphoma is that you can target lymphoma cells. You will deplete your own B cells, but we can mitigate that.

Dr. Justin Favaro
B-cell-based Immunotherapy

Robyn: “CAR T-cell therapy is a great new treatment, but as I understand, it targets all B cells and not just the cancerous ones, leading to a depleted immune system that can last a long time. Is there any current research on a similar immunotherapy treatment than can identify and attack the cancer cells and not the normal B cells?”

Dr. Ghosh: That would be something we would love to have. We are fortunate that we have been able to identify antigens. Dr. Favaro mentioned those spikes. Imagine if those spikes were not only in B cells but in liver cells, heart cells, and kidney cells, then CAR T-cell therapy would go and kill all of those.

Fortunately, this is what we can get away with as CD19 is expressed only in B cells but not in other normal tissues — not even on T cells or other parts of the immune system. Many other diseases don’t have that. We are starting to work with some solid tumors which have these, but it’s been difficult. Even in diseases like acute myeloid leukemia, you don’t have things that are specific to that cell.

With B cells, you’re more prone to infections, but you can still get IVIG, which is a immunoglobulin supplementation to help reduce your risk for infections. We currently don’t have spikes on the surface of just cancerous B cells but are absent on normal B cells, but that would be something which I hope the future researchers can identify.

Robyn: I believe there are studies that show B cell recovery over time. A lot of people will gradually recover and it doesn’t affect their remission rate. Everyone is unique. Some people with low IgG can get infections, some people do fine. There are patients who haven’t had CAR T-cell therapy who have primary B-cell aplasia and do fine and a lot of them don’t need IVIG. It’s a case-by-case situation. Most people have had some infection, but most people have been fine and living a normal life even without IVIG.

Dr. Favaro: The challenge with the solid tumor CAR Ts that they’re trying to make right now is finding the antigen on the lung cancer, for example, that won’t damage or destroy the lung. The fortunate part about lymphoma is that you can target lymphoma cells. You will deplete your own B cells, but we can mitigate that with prophylactic antibiotics, IVIG if needed, and taking precautions so you can still live your life.

Masking, especially if you’re in a crowded area, and frequent hand washing would be advisable. As more time passes, those restrictions start coming down a lot.

Dr. Nilanjan Ghosh
Post-CAR T-cell Therapy

Robyn: Michael asks, “What are the overall risks as far as activities, food, etc., for post-CAR T-cell therapy patients?”

I have not been avoiding anything for many years, but I’m eight years out at this point. There are initial precautions because a lot of people have low ANC (absolute neutrophil count) and some other depletion.

Dr. Ghosh: Right after CAR T-cell therapy, blood counts are low. Sometimes we even need to give growth factors to improve blood counts. The risk is going to be higher in terms of infections initially than a few months out. If the blood counts recover, especially neutrophil counts, then certain infection risks go down.

B cells always take time to recover. As the lymphocyte count recovery takes longer, your immune system is compromised and that’s where the possibility of viral infections happen. Masking, especially if you’re in a crowded area, and frequent hand washing would be advisable. As more time passes, those restrictions start coming down a lot.

Ultimately, you have to live your life, but still be cautious. If you do get an infection, then alert your providers so they can do some tests to find out if it’s a mild infection or something that needs to be worked up or treated.

In terms of food, you have to take certain precautions in terms of raw food while your neutrophil count is low, but that typically happens in the immediate post-CAR T-cell therapy phase. As more time goes, those usually are not an issue.

Robyn: You need to have a team take care of you. Your oncologist will move out of your realm because they have people who are very sick to take care of. I do encourage everyone to get an internist or an immunologist who can take care of the day-to-day.

New Treatment Options for Non-Hodgkin Lymphoma
Second CAR T-cell Therapy

Robyn: “Does CAR T-cell therapy work a second time if it didn’t keep the complete response the first time?” Can you have a second CAR T?

Dr. Ghosh: Not commercially. CAR Ts are approved once in the commercial setting, but we have clinical trials which will allow a second CAR T. For example, there’s a clinical trial using natural killer cells that are modified to become CARs or chimeric antigen receptor expressing cells. In that clinical trial, we allow patients who have had a commercial CAR T but it failed. Some of the allogeneic CAR T-cell therapy trials will allow patients who have had a previous CAR T-cell therapy.

There are other CAR Ts coming out. For example, we have a CD19/CD20 bispecific CAR T trial, which we are about to open. In that clinical trial, if someone had commercial CAR T, that is probably not allowed because the CD19 CAR T had already failed. But let’s say you have another clinical trial targeting CD22 and people have had the traditional CAR T, now you are using CAR T again but it’s different spikes. If you’re going against a different spike with a clinical trial, that would be doable. But if it’s the same one, then likely not.

The second time will be in a trial unless a CAR T-cell therapy gets approved that allows previous CAR T treatments.

New Treatment Options for Non-Hodgkin Lymphoma
Newer Monoclonal Antibodies

Robyn: Mike asks, “I’m still unsure about some of the things I’ve heard more recently because I don’t know if I have access to them. What about newer monoclonal antibodies? Do they still play a role?”

Dr. Favaro: There are definitely other options out there. Monjuvi is a monoclonal antibody against CD19 that has been looked at in relapsed lymphoma in combination with lenalidomide. Loncastuximab, which is one of these antibody-drug conjugates, is an anti-CD19 with a chemotherapy payload. It’s going to attach to your CD19 spike and internalize the chemotherapy right into that cell. It’s given via IV every three weeks.

These are two really good options for patients who, for whatever reason, CAR T-cell therapy or BiTE are not working or not available. These easily given off-the-shelf and approved by insurance.

When your blood counts are low and you’ve gone through therapy, there’s a risk of fungal infection as well.

Dr. Kulsum Bano
Cannabis & Non-Hodgkin’s Lymphoma

Robyn: “Cannabis and non-Hodgkin’s lymphoma. Are there any benefits?”

Dr. Bano: It’s a question that comes up pretty frequently. There may be some misinformation out there and some misconceptions of prevention of cancer with cannabis, and I don’t think there’s any founded data.

Certainly, people think about it in terms of symptom control. We do have medications that use the cannabinoid derivatives in a medical form, such as dronabinol, that we use for nausea and appetite stimulation for patients who have gone through chemotherapy.

Generally, we discourage smoking of cannabis only because there are a lot of additives that could be associated with it. When your blood counts are low and you’ve gone through therapy, there’s a risk of fungal infection as well.

There’s a lot of unregulated things that we don’t know what we’re dealing with. I don’t think there are any recommendations that can be definitely given. I don’t know that there are benefits per se, but it’s a discussion to have with your physician about what works for you and what doesn’t.

You need a small amount of protein, usually seafood, mostly vegetables on your plate, and some whole grains for carbohydrates. All these things are important.

Dr. Justin Favaro
Keto Diet

Robyn: “Can you speak about the keto diet? Is it effective against cancer? Is it helpful in any way?”

Dr. Favaro: It’s probably the most common question we get as oncologists every day. What can I eat? What should I eat?

My general recommendation is the Mediterranean diet. If you talk to nutritionists and look at the studies, you need several components to your diet. You need a small amount of protein, usually seafood, mostly vegetables on your plate, and some whole grains for carbohydrates. All these things are important.

I believe the keto diet takes out all carbohydrates, so you’re dealing with a lot of protein and a lot of fat. There are downsides of that for the rest of your body. Your cholesterol could go up and that could be damaging to your heart. Your body needs sugar and glucose.

For example, let’s look at a PET scan. What’s lighting up on the PET scan? Besides the lymphoma, it’s your heart and your brain. They need sugar to work. You don’t need sweets all the time, but you need complex carbohydrates. Maybe switch to whole grains and whole wheat pasta instead of white pasta. That’s only a portion of your diet, about 25%. The majority is vegetables and lean protein.

If you look at some of the recent studies that have come out that have looked at who lives the longest with cancer and what diet they follow, the winner seems to be the vegan diet in terms of cancer survival and decreasing risk of recurrence. This is cancer broadly and not lymphoma. But sometimes that’s a hard diet to follow, so a Mediterranean diet is a reasonable diet for most people to follow.

Robyn: Everybody wants control. You want control of your disease.

I have to add: Exercise helps. Studies in breast cancer and prostate cancer — because they’re so much more common and easy to study — showed that even for people who have never exercised before, if they walked 30 minutes a day, they had a longer remission rate and cure rate.

I encourage everyone to exercise. That doesn’t mean you have to do CrossFit because that may lead to shoulder injuries; we see that in radiology. You can do any type of walking or cycling. If you look at other studies, it’s not only the diet. People are active. Get yourself moving.

There have been studies done, not particularly in cancer, that show that insulin resistance is improved with intermittent fasting.

Dr. Kulsum Bano
Intermittent Fasting

Robyn: “Does intermittent fasting help patients with follicular lymphoma or any cancer? Does sugar play any part?”

Dr. Bano: There have been studies done, not particularly in cancer, that show that insulin resistance is improved with intermittent fasting. At any point, when you have dysregulation in your blood sugar control, that tends to lead to other medical complications. There is some role to play in improvement in outcomes. I don’t know that it’s been studied particularly.

Robyn: There are studies with BMI. People who are obese have a higher incidence of all sorts of cancers and have poorer outcomes. There are a lot of reasons for that. It’s multifactorial, but eating healthy and exercise make sense.

R-EPOCH vs. R-CHOP for Triple-Hit DLBCL

Robyn: “Is there any strong evidence that R-EPOCH is better than R-CHOP for triple-hit diffuse large B-cell?”

Dr. Ghosh: This type of aggressive lymphoma is one of the most aggressive variants. R-EPOCH is still considered as the standard of care for this disease based on a lot of retrospective data. There is no clinical trial taking patients with double-hit or triple-hit lymphomas and giving half of them R-CHOP and half of them R-EPOCH.

However, there was a large clinical trial which took all patients with diffuse large B-cell lymphoma and gave half of them R-CHOP and half of them R-EPOCH, and R-EPOCH was not shown to have a better efficacy. They were similar, but it was not really better.

That study was inconclusive in terms of the improvement for double-hit patients. If you ask most doctors, double-hit patients will still be getting R-EPOCH because there’s a lot of good retrospective data showing better long-term responses with R-EPOCH compared to R-CHOP.

We have an ongoing study where we are monitoring different types of cells post-CAR T-cell therapy.

Dr. Nilanjan Ghosh
Patient Group That Benefits More from CAR T-cell Therapy

Robyn: John asks, “We’ve talked about complete response rates and durable remission rates following CAR T-cell therapy. With the much larger patient population, have you seen any trends emerge as to which patients tend to do better in terms of a better response rate, a better complete response rate, as well as a more durable remission with CAR T-cell therapy?”

Dr. Ghosh: People have tried to figure it out. Before you start any treatment, you want to know if this treatment is going to give long-term remission for this person versus someone else. We are not there yet, but we have some ideas. It’s not perfect.

With CAR T-cell therapy, we know that if someone has very bulky disease and fast-growing bulky disease, CAR T-cell therapy will not give great outcomes. Unfortunately, nothing else does so people still go for it, but sometimes you want to debulk while waiting because CAR T-cell therapy is a weeks-long process.

For example, if there’s one site of bulk, we often can do radiation. There are new radiation techniques. One is called “boom boom” where short, very effective radiation is done to shrink the tumors, perhaps even express all these antigens, and have a better kill.

Bulky tumors can often cause T-cell exhaustion quickly so if they get overwhelmed with the tumor, then those T cells can get immune tolerance. There is also a subpopulation of these T cells that can cause immune suppression.

We have an ongoing study where we are monitoring different types of cells post-CAR T-cell therapy and checking them multiple times to see if we can identify patients who might have relapsed and had one type of immune repertoire versus those who had long-term remission and have a different type of immune repertoire.

We presented the initial data at ASH 2023, but hopefully, we’ll do a little bit more analysis on that and try to understand it better. We have samples taken pre-CAR T-cell therapy to see what may be the characteristics of a person that could predict long-term response.

We also have a study with BiTE. We are doing it for patients who are getting mosunetuzumab. We are collecting samples before and after treatment, and trying to identify which type of T cells may be associated with a better response versus a not-so-durable response.

CLL vs. Follicular Lymphoma

Robyn: Tim asks, “Can you define CLL and how it complements follicular lymphoma?”

Dr. Ghosh: CLL is chronic lymphocytic leukemia, which is under non-Hodgkin lymphoma. CLL is circulating disease in the blood. There is a lymphoma component to it called SLL, small lymphocytic lymphoma. It’s essentially the same disease. SLL is in the lymph nodes, CLL is in the blood. If there are more than 5,000 circulating lymphocytes, then it is a definition for CLL. If it’s below that, it’s called MBL, monoclonal B-cell lymphocytosis.

CLL is an indolent form of lymphoma circulating in the blood but could also be in the lymph nodes, spleen, and bone marrow. Like follicular lymphoma, it belongs to the same indolent non-Hodgkin lymphoma group considered as less aggressive.

CLL has tremendous progress where we have given up chemotherapy, so that’s where it’s a little bit different. You heard about R-bendamustine. We used to use that in CLL. In the past, we used to think we could use the same treatment for all indolent lymphoma.

We have relied on targeted treatment, like BTK inhibitors — ibrutinib was the first generation, then acalabrutinib and zanubrutinib, now pirtobrutinib — and then BCL2 inhibitors like venetoclax (VENCLEXTA). These have all come either in sequence or in combination.

Liso-cel got approved very recently for CLL, so now you have CAR T-cell therapy available as well. Chemotherapy was FCR and BR. We don’t really use those anymore. They’ve been shown to be inferior compared to these newer drugs that we have.

Introduction

Ruth Fein Revell, Patient Advocate

Ruth Fein Revell: Hi and welcome to our program, Clinical Trials Update: What to Know in Myelofibrosis Care. My name is Ruth Fein Revell and I’ve lived with a myeloproliferative neoplasm (MPN) for nearly 30 years.

I was diagnosed with essential thrombocythemia in 1995, polycythemia vera about 20 years later, and myelofibrosis in 2018. I’ve also lived with a number of complications from dangerous blood clots and hemorrhages that put me in the ICU to debilitating headaches, bone pain, and extreme fatigue.

I’m a health and science writer and very fortunate to be in a clinical trial for the last four years with amazing results, eliminating my symptoms, and significantly reducing my bone marrow.

I’d like to give special thanks to GSK for supporting this educational program. We want to note that The Patient Story retains full editorial control of this entire program. This is not meant to be a substitute for medical advice.

Joining us is Dr. Naveen Pemmaraju, a top expert in MPNs and myelofibrosis from MD Anderson. Dr. Pemmaraju, it’s so nice to see you. Thanks for joining us and for being a part of this program. Can you tell us more about yourself and what drew you to MPNs?

Naveen Pemmaraju, MD

Dr. Naveen Pemmaraju: Thanks for having me. I’m a professor of leukemia at MD Anderson in Houston, Texas. I serve as the executive director for cancer medicine and as the director for our rare disease program, including blastic plasmacytoid dendritic cell neoplasm (BPDCN).

I am an expert in both clinical trial research and patient care for patients with MPNs, including myelofibrosis, polycythemia vera, essential thrombocythemia, and mastocytosis.

Ruth: It’s always great to see you and to speak to you. You offer so much to the MPN community and we really thank you.

JAK inhibitors are not JAK2 mutant-specific inhibitors, so that’s why they work in patients whether they’re JAK, MPL, CALR, triple-negative, or have no mutations.

Dr. Naveen Pemmaraju

Standard of Care: JAK Inhibitors

Ruth: We now have four JAK inhibitors and one one of them was just approved. Walk us through this. First of all, how does a JAK inhibitor work?

Dr. Pemmaraju: The basic premise is that MPN cells signal through a specific pathway called the JAK/STAT pathway.

A regular cell uses the JAK/STAT pathway for normal blood cell growth, differentiation, and lifespan. Now take an MPN cell and that pathway is hijacked and used in a malignant way, so those cells keep growing and dividing. It’s like a light switch that’s turned on that doesn’t go off.

Interestingly, the JAK inhibitors are not JAK2 mutant-specific inhibitors, so that’s why they work in patients whether they’re JAK, MPL, CALR, triple-negative, or have no mutations.

JAK inhibitors are based on the principle that the JAK/STAT pathway and the cells are overactive and not working properly. JAK inhibitors aim to block that malignant activity and restore normal growth.

Ruxolitinib was the first-ever approved JAK inhibitor. Since 2011, three JAK inhibitors have been US FDA-approved: fedratinib in 2019, pacritinib in 2022, and momelotinib in 2023. The four currently approved JAK inhibitors have some interesting similarities and differences.

[Ruxolitinib] works very quickly in relieving the symptom burden for our patients with MPNs.

Dr. Naveen Pemmaraju
Ruxolitinib

Dr. Pemmaraju: Ruxolitinib, the first and longest in class, is a JAK1/JAK2 inhibitor. This drug was simply amazing in the original clinical trials, which were COMFORT-I and COMFORT-II, led by Serge Verstovsek and Professor Claire Harrison.

In those studies, we learned a few things about ruxolitinib. One is that it works very quickly in relieving the symptom burden for our patients with MPNs. It can shrink the spleen rather quickly as well, so quickly that the hallmark ended up being at week 24 by six months.

Some side effects to look out for over time in this otherwise well-tolerated drug have been the development in some patients of opportunistic infections, such as herpes zoster or shingles, weight gain, and non-melanoma skin cancers.

Basal cell and squamous cell cancers of the skin are already common in our patient population, so a lot of our patients end up seeing a dermatologist. Most of our patients don’t necessarily discontinue for those side effects, but we need to watch out for them.

All patients who are going to get treated with fedratinib should have their thiamine level checked.

Dr. Naveen Pemmaraju
Fedratinib

Dr. Pemmaraju: Fedratinib improves symptoms and decreases spleen size, but it has a very notable toxicity or side effect, which garnered an FDA black box warning. It’s a very serious potential side effect called encephalopathy. Some have seen it to be Wernicke’s encephalopathy, but on later analysis, not exactly.

Wernicke’s encephalopathy is a name for a syndrome that can cause problems with thinking and even balance and can result from severe nutritional deficiencies. For fedratinib, it appears that it displaces vitamin B1 (thiamine) so what we see is the linking of those. All patients who are going to get treated with fedratinib should have their thiamine level checked because the encephalopathy can be related to that.

Patients can have GI side effects with fedratinib, like nausea, vomiting, and diarrhea, so we have to watch out for that, particularly in our older and more frail patients.

The unique thing with pacritinib is for several years, it was being watched for the development of cardiac and/or bleeding signals.

Dr. Naveen Pemmaraju
Pacritinib

Dr. Pemmaraju: Pacritinib is an interesting agent. Again, all these are trying to hit the JAK/STAT pathway, but this hits other pathways outside of that and that may be part of its benefits and toxicities.

It helps to shrink down the spleen and improve the symptom burden of patients, but the unique thing with pacritinib is for several years, it was being watched for the development of cardiac and/or bleeding signals.

I and others have done a lot of evaluation and analysis, including post-approval. We’re not seeing a high signal for that, but that’s something you have to be aware of if the patient is on a blood thinner, having chest pain, or having heart surgery.

Not only did [momelotinib] show improvement in the spleen size and symptoms, but what’s interesting — and pacritinib is showing this as well — is having an improvement in anemia.

Dr. Naveen Pemmaraju
Momelotinib

Dr. Pemmaraju: Momelotinib is the most recently approved JAK inhibitor. Again, not only did it show improvement in the spleen size and symptoms, but what’s interesting — and pacritinib is showing this as well — is having an improvement in anemia. Now that’s important.

Ruxolitinib and fedratinib don’t necessarily do that and, in some cases, it can make it transiently worse. Momelotinib has ACVR1 inhibition. Pacritinib also showing that as well unleashes a new era for our patients of JAK inhibitors having beneficial side effects, such as improvement of anemia and potentially, thrombocytopenia.

You have to watch out for GI side effects with fedratinib, pacritinib, and even momelotinib. In the earlier studies of momelotinib, there was a signal for peripheral neuropathy. I want to put those forward as an overview. There are some subtleties and differences, if one reads further.

Ruth: Thanks for that explanation. I’ve heard a lot of people say that they have a different mutation, so a JAK inhibitor isn’t going to help them, but we know that that’s not the case, so thanks for your explanation of how they work.

There isn’t a single molecular test. The decision is based on clinical factors and the art of medical decision-making.

Dr. Naveen Pemmaraju
Switching JAK Inhibitors

Ruth: How do you know which JAK inhibitor might or might not work and which one to try first? How is that decision made?

Dr. Pemmaraju: The decision to switch JAK inhibitors is not scientific. We’re not there yet. At some point, I envision that we’ll have a decision tree, like our colleagues in CML. But right now, there’s no molecular test, so it is the art of medicine. It is clinical decision-making.

There are some factors, if one looks up in the NCCN and other guidelines. One is platelet count. Ruxolitinib and fedratinib should be given to patients who have a certain amount of platelets and that’s where pacritinib was able to get its approval.

Pacritinib is specifically approved in the front-line setting for patients whose platelet count is less than 50, for example. The NCCN guidelines and other groups say that once you use pacritinib in later lines, maybe you don’t have to pay attention to the platelet as much, but that’s obviously for debate.

Another factor is the GI signal. If you have someone who has a known encephalopathy syndrome or thiamine deficiency, then fedratinib is not going to be one that you would choose.

Finally, you have to look at some of these subtle side effects that we mentioned earlier, such as GI and neuropathy, to help you choose.

The bottom line is there isn’t a single molecular test. The decision is based on clinical factors and the art of medical decision-making.

Switching can have financial cost repercussions, new toxicities when a patient was otherwise doing ‘okay,’ problems with access to the drug, and could uncover idiosyncratic side effects that may be specific to that patient and weren’t seen in the studies.

Dr. Naveen Pemmaraju

Ruth: So it’s possible that somebody could start on one JAK inhibitor and at some point switch to another. Is that an issue if you change?

Dr. Pemmaraju: This is a great important point about switching JAK inhibitors and what are the indications. There are several buckets here.

First is clear disease progression in terms of the spleen. If you have a patient who’s been on a certain JAK inhibitor for a sufficient amount of time and you have a spleen that previously shrunk but now starting to rise again, that could be considered disease progression and an indication to switch.

Second is worsening MPN symptom burden to the point where the patient’s quality of life is affected.

Third is blast count, peripheral blasts or bone marrow blasts, going up.

Fourth is the progression of the disease to an outright higher level of disease, what we call an accelerated blast phase.

The development of these clinical factors, such as the platelet count, may matter if you have a patient who’s on ruxolitinib, for example, and you consistently have platelets below 50, then that’s an indication to switch, for example, to pacritinib. If you have a patient who has anemia, you may think about momelotinib.

These are some of the reasons to think about switching. But again, there isn’t a molecular test or a definitive moment to switch. Switching can have financial cost repercussions, new toxicities when a patient was otherwise doing “okay,” problems with access to the drug, and could uncover idiosyncratic side effects that may be specific to that patient and weren’t seen in the studies.

Finally, you have a question about withdrawal and overlap, so these are things I think we’ll all work out together over the coming years as we have these JAK inhibitors in the clinic.

The story of JAK inhibitors is an evolving story and it’s evolving at three levels.

First is the science of it alone. In 2005, I was at Johns Hopkins with Alison Moliterno and Jerry Spivak, and I remember the day that the JAK2 mutation V617F was elucidated. From that time to now, we have JAK inhibitors that are amazing, so science is still evolving.

Second is the clinical part, as we’ve discussed. When to switch, how to switch, what are the factors, etc.

Third is the future. How do we combine these drugs with a second agent and potentially a third agent? What are those cross-reactivities? How does that benefit the patient to start those upfront rather than later on? You have this evolving area that’s quite exciting but also quite daunting not only for the patients and the clinic but for researchers.

This is preliminary data, but it was so encouraging that they are now moving on to a phase 3 randomized global study.

Dr. Naveen Pemmaraju

Clinical Trials: Combination Therapy

Selinexor & Ruxolitinib

Ruth: We’re seeing some really exciting updates as far as combination therapy. Let’s talk about clinical trials, starting with selinexor plus a JAK inhibitor and then move on to other combinations.

Dr. Pemmaraju: At ASH 2023, Dr. Sri Tantravahi from Utah presented the first public data of front-line combination, updated I should say, of selinexor with ruxolitinib. This is untreated patients with myelofibrosis, intermediate to high risk, who were given the combination rather than ruxolitinib, which would be considered the standard or JAK inhibitor.

Although it was early on and only a few patients, very surprisingly and amazingly, the group showed that there’s a high rate of activity in spleens being reduced as well as symptom burden being increased.

Now, this is preliminary data, but it was so encouraging that they are now moving on to a phase 3 randomized global study. The combination selinexor-ruxolitinib, so the XPO1 inhibitor plus JAK inhibitor, versus JAK inhibitor alone. Those data will be eagerly awaited.

This is also, if I may say, a fascinating study.

Dr. Naveen Pemmaraju
Navitoclax & Ruxolitinib

Ruth: What about the BCL inhibitor navitoclax?

Dr. Pemmaraju: A second combination is that of the BCL-XL inhibitor navitoclax with ruxolitinib, which I presented as an oral presentation at ASH on behalf of my colleagues. This is also, if I may say, a fascinating study.

We globally enrolled 252 patients into a randomized, double-blind, placebo-controlled study of ruxolitinib plus navitoclax, which is not yet approved for any indication, versus ruxolitinib alone. Again, we had intermediate to high-risk patients, around 80-plus percent of intermediate-2 patients.

What we found is a very outstanding rate of 60-plus percent of patients in the combination arm having an SVR35 at week 24, so spleen volume reduction of 35% or more, versus only 30-plus percent in the control arm, which was ruxolitinib alone. The waterfall plot showed that almost all patients benefited from the combination.

In terms of statistical analysis, the primary endpoint of spleen reduction was met with a high statistical significance, but the symptom burden difference was not yet found to be statistically significant. Both groups had reductions, so there was a numerical reduction of the symptoms in both the combination and the ruxolitinib alone, but there was no statistical difference.

The study is ongoing for collecting for maturity and overall survival duration, so this was a preliminary presentation at 15 months follow-up. We’ll stay tuned to see how it gets updated over the next congresses.

Great safety, but you have to watch out for thrombocytopenia, which is low platelets, and watch for that signal very closely.

Luspatercept & Ruxolitinib

Ruth: Another combination being investigated is the use of a shot called luspatercept to boost hemoglobin or fight anemia, and that also is being used with ruxolitinib. Can you tell us more about that one?

Dr. Pemmaraju: Luspatercept is a fascinating molecule. It’s already FDA-approved in the myelodysplastic syndrome setting. In the MPN setting, we think it has a similar activity to improve hemoglobin and anemia, which is an urgent, unmet medical need.

The initial studies have shown positive data, which is either luspatercept by itself, usually given every three weeks, or in combination with the JAK inhibitor ruxolitinib. Those studies are ongoing and we eagerly await those results in the coming year or two.

When the group looked back at certain subsets, including the intermediate-1 patients and others, it appeared that there was a benefit in both spleen size and symptoms.

Dr. Naveen Pemmaraju
Pelabresib & Ruxolitinib

Ruth: We’ve also had the MANIFEST trial, which is the trial that I happen to have been on for the last four years, and that’s a different drug, s pelabresib. Could you talk about that combination and what you think the potential is?

Dr. Pemmaraju: Another exciting combination presented at ASH 2023 was that of the MANIFEST-2, which is ruxolitinib plus a new agent pelabresib, a bromodomain or BET inhibitor, which is not yet FDA-approved for any indication.

This encouraging data set was presented by Dr. Raajit Rampal from Memorial Sloan Kettering. It’s the second-largest study ever conducted in the myelofibrosis front-line space, which included 430 patients. They also randomized ruxolitinib-pelabresib versus ruxolitinib alone in the control, mostly intermediate-1 to intermediate-2 patients, so a slightly different population.

They showed a very similar profile. A highly statistically significant primary endpoint was met, which is SVR35 at week 24. The symptoms in all comers, although showing a numerical decrease in both groups, did not quite meet statistical significance.

When the group looked back at certain subsets, including the intermediate-1 patients and others, it appeared that there was a benefit in both spleen size and symptoms.

The supposition is the same as navitoclax. These two are the first ever in our field, resulting in phase 3 global, double-blind, placebo-controlled, front-line, untreated myelofibrosis patients with a novel combination of pelabresib and navitoclax, neither of which are FDA-approved for any indication.

I would say my editorial comment is super exciting for the field that we even did it. Both were international studies largely conducted during the pandemic and involved lots of patients and investigators.

The primary endpoint was met for both of them. The symptoms were not quite met in either study in terms of statistical significance so the question asked is three-fold.

What is the utility of following the symptom burden scale in combination studies, something that was designed 15 years ago for a single-agent JAK inhibitor?

Do we expect a combination to improve symptoms over ruxolitinib alone, or because you’re introducing a second drug, you’re going to introduce new toxicity?

On behalf of my colleagues, maybe it’s time to reevaluate: what are the endpoints for our patients with myelofibrosis? Perhaps in addition to reducing spleen size and improving symptoms, we should be factoring in overall survival, progression-free survival, and bridging to stem cell transplant. This is the time to talk about it because these combination studies are difficult, if not impossible, to judge based on the COMFORT-I and COMFORT-II studies.

Imetelstat is in an ongoing phase 3 trial, which is in the second-line setting and beyond, against the best available therapy (BAT).

Dr. Naveen Pemmaraju
Telomerase Inhibitors

Ruth: Let’s go beyond JAK inhibitors. There are other drugs being studied. Can you help us understand other approaches?

Dr. Pemmaraju: There’s an exciting alphabet soup of clinical trials and drug molecules out there. It’s exciting for our patients to know that there are people around the world who care about MPNs, so it’s good to know that despite COVID, we have a lot of innovation.

We’re adding a new trial once a week, so it’s almost impossible to keep up, but I do want to give some sampling of what’s going on.

Imetelstat is very important for everyone to know. It’s a first-in-class telomerase inhibitor. Some people have heard of telomeres. They are the little ends on the ends of chromosomes that help to determine aging and possibly even cancer biology.

Imetelstat is in an ongoing phase 3 trial, which is in the second-line setting and beyond, against the best available therapy (BAT). I praised this trial because it’s the first and, to my knowledge, only phase 3 trial that has overall survival as its primary endpoint. Hopefully, it will give us a readout in the next year or two.

MDM2 Inhibitors

Dr. Pemmaraju: MDM2 inhibitors have gotten a lot of press in all MPNs. This is a key pathway that has to do with guarding the cell TP53. It’s an oral drug that has been studied before. As a class of drugs, there may be some GI side effects to watch out for, but in the later trials we’ve seen, the groups have figured out a way to address that by either adjusting the dosing schedule or dosing frequency.

I’m excited to see where that area goes. Right now, the lead trials are MDM2 inhibitors with ruxolitinib as an add-on approach or a suboptimal approach. You’re already on a JAK inhibitor. You have an okay response, not a great one, but not quite ready to come off of it, and then you add the MDM2 inhibitor. Those studies are actively ongoing and I think we’ll be excited to see those results.

The good thing about myelofibrosis is whether you’re JAK, CALR, MPL, or triple negative, you respond to JAK inhibitors and novel agents alike.

Dr. Naveen Pemmaraju

Genetic Mutations in Myelofibrosis

Ruth: What if someone’s myelofibrosis isn’t driven by a JAK mutation but a different mutation, is there a different approach? We’ve also been hearing about a cancer vaccine related to CALR, so could you walk us through both?

Dr. Pemmaraju: There’s a two-part answer to the question of molecular mutation targeting in MPNs. Historically and in the clinic right now, there is no difference at the moment.

The good thing about myelofibrosis is whether you’re JAK, CALR, MPL, or triple negative, you respond to JAK inhibitors and novel agents alike. That’s an interesting thing that suggests that there’s a common pathway.

But for the future, yes. Already in the clinic in 2024, we expect a new era to begin, which is, for the first time, to have mutant-specific approaches for both JAK2 and CALR. I expect that we’ll see multiple different drugs targeting mutant JAK2 specifically. The hypothesis is: could that be better and more specific than targeting the whole pathway? Let’s see. You’ll see phase 1 trials there.

CALR turns out to be a really good target, especially for immune therapy targeting. That’s only new science in the last five years. There are vaccine approaches either by themselves or with other immune drugs, such as ipilimumab. There’s an exciting bispecific molecule, which is a mutant CALR x CD3 bispecific antibody that I and others will be working on.

There are also going to be other ways to target CALR. You have multiple different ways of targeting mutant-specific approaches, but let me highlight these are phase 1 clinical trials. They’re backed by animal preclinical data. Now we need to see how they do in the initial trials.

For the first time, I’m seeing sustained improvement in the anemia of MPN, specifically myelofibrosis. We have three different categories trying to address this for our patients.

Dr. Naveen Pemmaraju

Anemia in Myelofibrosis

Ruth: Dr. Pemmaraju, you mentioned that many people suffer from anemia when hemoglobin is low. We know they can feel extremely fatigued so much that it interferes with their quality of life, which I know from personal experience, unfortunately. With what you’ve described, do you feel like we’re getting better tools to fight anemia and hopefully avoid people needing more frequent transfusions?

Dr. Pemmaraju: Yes. For the first time, I’m seeing sustained improvement in the anemia of MPN, specifically myelofibrosis. We have three different categories trying to address this for our patients and it’s simply exciting.

First is the JAK inhibitors themselves. As we mentioned earlier, the first initial ones did not improve and may have worsened the anemia transiently in some patients. Now these second- and third-generation JAK inhibitors are improving the anemia and possibly through the inhibition of ACVRL1, so that’s exciting.

Second is the additional agents, such as luspatercept. You can add on an agent that works outside of the JAK inhibitor that aims to stimulate the hemoglobin and improve the anemia.

Third is these novel agents. When you look closely at the navitoclax and pelabresib data sets, in those two particular instances, you have some people who get anemia as toxicity, but you also have patients who have anemia improvement with the combination, maybe better than with ruxolitinib alone. These three approaches, we’re already seeing in the clinic in phase 1, 2, and 3 clinical trials.

Out of all of these theoretical things, a lot of times what our patients are suffering from is anemia. When the hemoglobin gets below 7, 6, 5, or 4, it’s not even compatible with life, much less quality of life. Anything we can do to reduce the burden of getting transfusions, missing appointments, and missing life events is going to be a big breakthrough, and I’m starting to see that.

If a transplant is available and indicated, it is the only curative approach for myelofibrosis.

Dr. Naveen Pemmaraju

Role of Stem Cell Transplant in the Treatment of Myelofibrosis

Ruth: Typically, a doctor will tell a patient that the only cure for myelofibrosis is having a stem cell transplant. With these new medical therapies, my question is always the same: do you see a changing role for transplants?

Dr. Pemmaraju: The role of stem cell transplant in myelofibrosis is one of great importance still. While I’m personally excited about all of these drugs in development, two things are important.

First, none of these have been shown to create a long-term cure in and of themselves for myelofibrosis. Second, if a transplant is available and indicated, it is the only curative approach for myelofibrosis.

Having said that, the realistic problem with allogeneic transplants is that it’s not available for everyone because of their comorbidities, how frail versus how fit they are, matching, the infection rate, and the mortality rate. As patients get older, it may be tougher at some centers and for some folks to do it. There are some real limitations.

The other problem is that out of all of our patients, the vast majority are not going to transplant. Improvements are being made with transplants every day. Haploidentical transplant, which is a half match, is becoming more of a standard, so that gives the donor pool exponentially more options.

Trying to reduce graft versus host disease, which are complications after the transplant, with medicines are revolutionizing the field.

As I’ve traveled all over the world, people can do stem cell transplants in economically diverse situations. The transplant procedure itself can be highly expensive. Interestingly, even though cost-effectiveness is an issue, in some locales, if you can do a transplant and potentially cure the disease, it can lead to an improvement in socioeconomic status overall.

There are some cool, important things happening. But it’s an important point that even with all the excitement of these medicines and medicine combos, we’re still not at the point where we’re talking about a cure, so if you have the availability and indication for transplant, you have to pursue that consideration.

We have brand new approaches that we didn’t have a few years ago. There is a lot of data and science, so there’s hope.

Dr. Naveen Pemmaraju

Final Takeaways

Ruth: Let’s put all of this together. For those of us living with myelofibrosis or others who are concerned about progressing to myelofibrosis, what do you want to leave them with? When you total up everything we’ve talked about, how do you want to leave the conversation?

Dr. Pemmaraju: This discussion was very exciting because it left me with even more hope than when I started the day. I would leave our patients, caregivers, family members, advocates, and stakeholders with a message of hope and positivity. It’s not blind hope and positivity. It’s not based on hunches or ideas. It’s based on data.

The last three years in particular, I would call it — and I do not use this phrase lightly — a golden era for research for the MPN, specifically including myelofibrosis.

There are four areas to highlight and to be very excited about for our patients and families. First is the development of new JAK inhibitors. We mentioned the four that are already approved in the US, so let’s get them available all over the world. There are several more in clinical development.

Second is the JAK inhibitor combinations. Very exciting data from ASH. Let’s see the new combinations. Maturing data for navitoclax, pelabresib, and selinexor.

A third area of excitement and hope is that of anemia-improving agents.

Finally, the delineation, description, and demonstration of brand-new molecular pathways inside the cells that were never known before. New insights and ways of approaching. We mentioned potential immune therapy approaches, like the CALR mutation. It’s exciting that we have brand new approaches that we didn’t have a few years ago. There is a lot of data and science, so there’s hope.

Ruth: Dr. Pemmaraju, thanks so much for being with us today. You’re always a pleasure to talk to and so informative to our guests. We really appreciate your time.

Dr. Pemmaraju: Thank you so much for having me. This was a very thought-provoking and stimulating discussion.

Sam Siegel, MD, Patient Advocate

Dr. Sam Siegel: Thanks, Stephanie! I’m a two-time Hodgkin’s lymphoma survivor, bone marrow transplant survivor, and primary care physician doing survivorship medicine. I’m here to have this wonderful conversation with Dr. Natalie Grover and Dr. Stephen Ansell about Hodgkin lymphoma updates.

Natalie Grover, MD

Sam: Dr. Natalie Grover is a hematologist-oncologist at the UNC School of Medicine. She’s the clinical director of the cellular therapy program, leads several CAR T-cell therapy clinical trials in lymphoma, and strives to improve treatment options and quality of life for lymphoma patients.

Dr. Grover, can you tell us a little bit about yourself, what drew you to lymphoma, and about your approach to patients and how you care for them?

Dr. Natalie Grover: I was drawn to oncology as a maternal medicine resident. Much of it was based on my relationship with patients whom I saw in the inpatient oncology ward. When I saw those patients, I always wanted to go back and find out more about what happened to them and form connections with them.

There were so many discoveries and new treatments available. Even during residency, the treatment landscape was changing so much and that drove me to oncology.

I like how heterogeneous lymphoma is and how it involves a wide patient population of both young and older patients. It’s truly a systemic disease. There are so many different types of lymphoma so my clinic is a very heterogeneous mix of different patients and I enjoy that.

Sam: That makes a lot of sense. Lymphoma is the umbrella, but it’s a lot of different diseases that can affect multiple parts of the body. I could see how that’s interesting.

Dr. Natalie Grover profile
Stephen Ansell, MD, PhD

Sam: Dr. Stephen Ansell is a hematologist-oncologist at the Mayo Clinic who studies and specializes in Hodgkin’s lymphoma. His research has led to the use of immune checkpoint therapy in lymphomas, which is a very exciting development. His goal is to translate his research into new treatment approaches.

Dr. Ansell, can you tell us about your path into lymphoma, what drew you to the field, and your approach to patients?

Dr. Stephen Ansell

Dr. Stephen Ansell: I trained in South Africa. I was very focused on internal medicine, but they needed someone to do some work temporarily in oncology and assigned me. 

When I got there, similar to Dr. Grover, I was excited about the opportunity, the disease, the patients, and how we could make a difference based on the fact that treatments were highly effective and beneficial. Patients benefited substantially even from initial treatments back in the day of more chemotherapy.

What has been exciting for me throughout my career has been to see how we can change treatments by increasing the number of people who benefit and hopefully get cured, and decreasing the side effects and toxicities by being able to find effective therapies that aren’t that hard on patients.

Sam: Your areas of interest and passion are so personally meaningful to me and my lymphoma journey, and I think will resonate with a lot of people.

Even though I had some side effects from the brentuximab at the highest dose that I first started it on, it still felt like a cakewalk compared to my initial drug regimen.

Dr. Sam Siegel

Sam’s Hodgkin Lymphoma Story

Sam: I was diagnosed with stage 2AE Hodgkin’s lymphoma and the reason that 2AE is important is because E means extranodal manifestations. I had some lung involvement and it was confusing whether or not I was a stage 2 with right around the lymph nodes in that lung or stage 4. That was going to impact how many months of chemotherapy I would have.

I started with ABVD chemotherapy. Within two months, the initial cough that I had at the time of diagnosis improved pretty quickly. Towards the end of those two months, I started getting a cough again. My PET scan looked good so the thought was that bleomycin was probably to blame for that cough.

We dropped bleomycin and it felt pretty okay making that decision. I suspected that something else was going on, but because the scan had come back clean, we decided to watch and wait.

Samantha S. ABVD
Samantha S. 39th birthday at Brentuximab infusion

About a month or two after that, I developed symptoms that were eerily reminiscent of my initial diagnosis, such as wheezing in the upper left side of my chest, which I knew wasn’t normal, and a pea-sized lump above my collarbone in a very similar location to where the initial lump was.

I suspected that those were Hodgkin lymphoma symptoms and sought care right away. The PET scan showed that I was most likely having a relapse.

It was a process to get the tissue to confirm the relapse. I had to have three biopsies, with the third one involving a thoracic surgery to get a lymph node right near my heart.

By that time, I felt so beaten up by traditional cytotoxic chemotherapy. New information was coming around about salvage therapy, which is the therapy after a person has relapsed from initial therapy. At that time, I didn’t feel that I could go through another few months of multi-drug traditional cytotoxic chemotherapy.

Data was coming out about brentuximab, an antibody-drug conjugate, and using that as a bridge to autologous bone marrow transplant. My oncologist said, “These trials showed that this could be an effective bridge to transplant. What do you think?” I said yes because I wanted to go for the therapy with the least amount of toxicity.

Even though I had some side effects from the brentuximab at the highest dose that I first started it on, it still felt like a cakewalk compared to my initial drug regimen.

That goes to show how important the science is and the clinical trials that inform oncologists how to adjust therapies, especially therapies that were traditionally pretty toxic in terms of long-term and late-term effects.

There are always ways in which we’re trying to make treatment better… we’re trying to replace radiation therapy by utilizing new agents.

Dr. Stephen Ansell

Standard of Care: First-Line Treatments

Sam: Dr. Ansell, can you tell us about the current standard first-line treatments and their efficacy for Hodgkin lymphoma?

Dr. Ansell: In many respects, we think about it in two buckets: people who have more limited-stage disease (only on one side of the diaphragm, either above or below) or advanced-stage disease (both sides of the diaphragm, in the bone marrow, or other tissues).

With limited-stage disease, we again think of two buckets. These are different symptoms and other tests to determine prognostic factors. If you have favorable prognostic factors, we treat you with very minimal chemotherapy. If you have more symptoms and unfavorable factors, we will treat you with a little bit more treatment. If you have advanced disease, we give you more treatment yet again.

There are always ways in which we’re trying to make treatment better, but the most standard way is if you have very limited disease with good favorable factors, we often will give two rounds of chemotherapy treatment and then consider consolidation radiation treatment.

If you have a more advanced disease, still limited to one side of the diaphragm but with more unfavorable factors, we would give more chemotherapy and more radiation treatment. Then for advanced-stage disease, we would give chemotherapy and no radiation treatment.

However, we’re trying to replace radiation therapy by utilizing new agents. We’ve used PET scans to tell us who might need extra treatment or not. I have to hedge a little bit because a lot of it is individualized and that’s the most important thing.

It’s so important to raise awareness about the importance of being involved in clinical trials and knowing that you don’t have to have failed multiple lines of therapy before you consider them.

Dr. Sam Siegel

Sam: Absolutely. How do you decide? There are different prognostic systems so if somebody is unfavorable in one and favorable in others, how do you factor that in?

Dr. Ansell: Pick one system and utilize the data supported by that system. The German Hodgkin Study Group has done a lot of work in this space. In our practice, we tend to use the prognostic system that they use because that helps us standardize treatment.

What we want to do is always push the envelope. We encourage people to participate in clinical trials that are testing new ways compared to the standard ways to see if we can optimize treatment even further.

Sam: I love that. Thank you for bringing up clinical trials. It’s so important to raise awareness about the importance of being involved in clinical trials and knowing that you don’t have to have failed multiple lines of therapy before you consider them.

Clinical trials can be for everyone and there are so many different types of situations where somebody could need a clinical trial. We’re looking at things to de-escalate therapy or alter treatments based on a patient’s situation.

Dr. Ansell: I would say you’re exactly right. The most impressive and important data that has come out on Hodgkin lymphoma is in the front line based on recent clinical trials. Everyone needs to remember that what we do currently is based on people who have participated in clinical trials that have changed how we practice.

Standardly, we utilize new agents, like PD-1 blocking antibodies or brentuximab vedotin plus chemotherapy, rather than chemotherapy alone because that’s improved the outcome of patients. Especially in advanced-stage patients, that’s now the standard of care.

The two biggest drugs that have transformed the care for Hodgkin lymphoma in the past 5 to 10 years are brentuximab vedotin… and checkpoint inhibitors.

Dr. Natalie Grover

Latest Advancements in Treatments

Sam: Dr. Grover, what are some of the newest and hottest treatments for Hodgkin lymphoma?

Dr. Grover: I think the hottest advances in Hodgkin lymphoma are related to incorporating some of these new treatments into earlier lines of therapy to try to both improve outcomes so increase the chance of cure and reduce long-term toxicities.

The two biggest drugs that have transformed the care for Hodgkin lymphoma in the past 5 to 10 years are brentuximab vedotin, which is an antibody-drug conjugate. It delivers chemotherapy specifically to the cancer cells.

The cancer cells in Hodgkin lymphoma have a marker on them—CD30—that’s pretty much universally seen in all the Reed-Sternberg cells, the cancer cells in Hodgkin lymphoma. Brentuximab specifically targets those.

The other drugs are what people may have heard of called checkpoint inhibitors. These immunotherapies help the immune system fight Hodgkin’s lymphoma.

When they incorporated these drugs—nivolumab, pembrolizumab, and brentuximab—they were successful in relapsed/refractory disease. Now they’re being moved to earlier lines of therapy to try to reduce the amount of chemotherapy that we’re giving patients and hopefully to enhance care in these patients.

By limiting chemotherapy and radiation, can you improve patient outcomes?

Dr. Natalie Grover

Sam: How about some recent clinical trials for reducing toxicity? I heard about AHOD2131.

Dr. Grover: There’s a clinical trial for pediatric and adult patients looking at whether we can incorporate these newer treatments, brentuximab and checkpoint inhibitors, in newly diagnosed Hodgkin lymphoma patients.

Everyone gets two cycles of standard chemotherapy then patients get randomized to either getting these new treatments, brentuximab and nivolumab, or continuing to standard chemotherapy.

The question is: by limiting chemotherapy and radiation, can you improve patient outcomes? One thing they want to look at is cure rates and long-term survival from a Hodgkin’s standpoint, but they’re also collecting data looking at quality of life patient-reported outcomes.

The top priority is curing their lymphoma, but we also want to think about the quality of life for patients moving forward and making sure that they live long lives.

Dr. Natalie Grover

Sam: That’s incredible. When you’re talking about late-term effects or reducing toxicities, what are some of the things that we’re trying to reduce long-term?

Dr. Grover: One of the chemotherapy drugs that we give patients can affect their heart function so some of the things that we think about are the risk of heart disease down the line.

One of the drugs that we’re using a lot less often now can affect lung function so we look at issues with lung function past therapy.

With some of these drugs and using more brentuximab, another thing that we’re thinking about is neuropathy. Patients can have some nerve damage and issues with pain, numbness, and tingling or doing different functions, like texting, typing, or writing.

With young patients, another thing we think about is fertility. Even though many of these patients can have children in the future as a lot of these earlier treatments don’t have as big an effect on fertility, it’s still something we think about, especially if we need to escalate people who have a disease that relapses or need more aggressive therapies.

We also think of secondary cancers. Some chemotherapy and radiation may increase the risk of having other cancers.

The positive is that most of these patients live long enough for us to focus on that and think about these effects. The top priority is curing their lymphoma, but we also want to think about the quality of life for patients moving forward and making sure that they live long lives.

Checkpoint inhibitors help the immune system fight the cancer. Some of these patients may stop responding to checkpoint inhibitors so there’s interest in using other types of treatments in combination.

Dr. Natalie Grover

Sam: What about trials to re-sensitize to PD-1 drugs? What does that mean?

Dr. Grover: Checkpoint inhibitors are effective in Hodgkin lymphoma. Right now, we’re moving them to earlier lines of therapy but these are treatments that can also work well for relapsed and refractory patients.

Hodgkin lymphoma is unique because, compared to other lymphomas, there aren’t that many cancer cells in these patients. When pathologists look at cells, there are a lot of immune cells around the cancer cells so there aren’t that many lymphoma cells. A lot of it is your immune reaction to the lymphoma.

Checkpoint inhibitors help the immune system fight the cancer. Some of these patients may stop responding to checkpoint inhibitors so there’s interest in using other types of treatments in combination. If a patient progresses on pembrolizumab or nivolumab, can you combine them with other treatments and re-sensitize your immune system so they can be sensitive again to these treatments? There’s some research looking into that.

We’ve also seen patients get the reverse. These treatments may reset the patients in some way. Patients may get checkpoint inhibitors and then after that may respond better to other treatments. There have been some studies showing that after checkpoint inhibitors, even if they progress on those drugs, patients potentially respond better to chemotherapy or other treatments.

Sam: We’re still learning how these drugs impact the immune system and how they might make you respond better to traditional chemotherapies, even if you didn’t initially. That’s incredible.

Dr. Grover: The current biggest advances are in advanced-stage Hodgkin lymphoma. More recently, brentuximab was incorporated in addition to chemotherapy. Dr. Ansell was part of that study. That improved overall survival in advanced-stage Hodgkin lymphoma patients compared to standard of care.

We can see the progression from old-style chemotherapy to immune checkpoint plus chemotherapy as the front-line treatment.

Dr. Stephen Ansell

Early vs. Advanced Stage Advancements

Sam: Dr. Ansell, can you tell us about the SWOG S1826 trial and what that showed?

Dr. Ansell: Picking up again on the theme of better therapies getting better outcomes and using some of the new drugs that we’ve touched on, as Dr. Grover said, the management of advanced-stage patients has moved over time.

Back in the day, we gave ABVD chemotherapy and tried to leave out bleomycin, which causes lung toxicity, if patients were doing well based on PET scans.

These new drugs, brentuximab vedotin being the first one, were brought into the combination in place of bleomycin. It’s now brentuximab with AVD. When compared head to head, it showed that brentuximab improved the outcome of patients—not only their likelihood of staying in remission but their overall survival.

It was then compared as the standard to nivolumab, the PD-1-directed therapy, plus AVD chemotherapy in place of bleomycin. That then showed progression-free survival at a one-year follow-up. We don’t have mature data yet, but it seemed better already than the brentuximab-AVD chemotherapy and, as Dr. Grover touched on, less in the way of side effects and better tolerated.

That’s likely to become the new standard for advanced-stage patients. We want to see a little bit more mature data. But certainly, in elderly patients where toxicity is a real challenge, this has become a standard for many. We can see the progression from old-style chemotherapy to immune checkpoint plus chemotherapy as the front-line treatment.

Sam: These are exciting times. It’s wild because, for decades and decades, it seemed like we were doing the same thing for Hodgkin patients. Even if I were diagnosed with the same clinical scenario now compared to when I was first diagnosed in 2021, I would be treated differently.

There is still a subset of people where the disease proves to be very challenging and keeps relapsing… We still see patients who have gone through this standard treatment using these new drugs and then the disease comes back yet again.

Dr. Stephen Ansell

Gaps Clinical Trials are Filling

Sam: Can you tell us about these clinical trials and what gaps they fill?

Dr. Ansell: You heard us talk about two new drugs. They came from the relapsed setting but have moved up to front-line treatments. The gaps are for patients, heaven forbid, who have gone through these new therapies.

There is still a subset of people where the disease proves to be very challenging and keeps relapsing. That group’s getting to be smaller and smaller so that’s the good news. The challenging point is that it’s never good enough until there’s nobody in that group. We still see patients who have gone through this standard treatment using these new drugs and then the disease comes back yet again.

Things that are becoming exciting and that we need to do better on is what to do for those patients. Additional treatments that target these other immune checkpoints aside from PD-1 and other ways to make the immune system wake up and do its job are being tested.

The work that Dr. Grover and her team do is taking your immune cells, sending them to “training camp” to get a little docking site on them so they can detect the cancer in a much better way, and then unleashing them on the cancer. That’s proving exciting.

Finally, what we call bispecific antibodies. Those are also being tested and are some of the exciting opportunities in the future.

One arm of the antibody is directed to CD30, but the other arm grabs onto CD3 in the T cells.

Dr. Stephen Ansell

Bispecific Antibodies

Sam: Can you tell us about bispecific antibodies?

Dr. Ansell: This is an area that’s growing fast in Hodgkin lymphoma. Dr. Grover talked about CD30, which is on the cancer cells. One arm of the antibody is directed to CD30, but the other arm grabs onto CD3 in the T cells.

Bispecific antibodies bring those cells into very close proximity to each other. Like your kids in the back of the car who don’t like to sit next to each other and keep poking each other, this causes those cells to be grumpy with each other. The T cells, your immune cells, will then fight the cancer. That’s really what you want to see.

We talked about immune checkpoints that make T cells do a better job. One of the ways we’re doing that is on one arm, PD-1, which is an established immune checkpoint, but on the other, something like TIM-3, which is another immune checkpoint.

Other ways in which T cells are being switched off are now protected so it’s making those cells even more efficient. Those are two of the main ways bispecific antibodies are being tested right now.

With CAR T-cell therapy, we have seen some nice responses in patients whose disease has progressed after many different therapies, but there’s still work to do to improve these therapies.

Dr. Natalie Grover

CAR T-cell Therapy

Sam: Dr. Grover, how about CAR T-cell therapy and post-transplant relapses? Can you tell us about that and where CAR T-cell therapy might play a role?

Dr. Grover: As Dr. Ansell briefly mentioned, CAR T-cell therapy involves taking a patient’s T cells, sending them off, and re-engineering them so they can specifically target the CD30 protein on the cancer cell.

We have a CAR T-cell therapy trial at UNC and at the Baylor College of Medicine. There are two academic trials where we’re studying these CAR T cells in patients with Hodgkin lymphoma. There are also a few international trials. I know there’s a group in Spain and China.

Unfortunately, there isn’t a company-sponsored trial. They’re exciting treatments, but they’re not as easily accessible. Patients do need to travel for these for these treatments.

The big thing is long waiting lists, but we are hoping to get more patients treated more quickly because it still shows that there is an unmet need. Some patients have not responded, progressed after brentuximab, progressed after checkpoint inhibitors, progressed after transplant, and need additional options for treatment.

With CAR T-cell therapy, we have seen some nice responses in patients whose disease has progressed after many different therapies, but there’s still work to do to improve these therapies.

Right now, we have some patients who have been in remission for many years—five-plus years after getting CAR T cells. Many patients get the CAR T cells and have a great response, but their disease relapses afterward. We’re trying to figure out why that’s happening and how we can improve the CAR T cells and improve outcomes for patients.

Patients who relapse can have more aggressive disease as opposed to some other more aggressive types of lymphoma, but with Hodgkin, patients who have relapsed oftentimes can live a long time even with the disease.

Dr. Natalie Grover

Dr. Ansell: There’s one other option that takes both bispecifics and cellular therapies and combines those strategies. That’s taking the natural killer cells from cord blood and using a bispecific antibody that targets CD30 and a protein called CD16 on the NK cell. It sticks this bispecific antibody to the NK cell.

They pre-treat the NK cells before they give them to the patient and then infuse them. You activate the cells outside the body, add the bispecific antibody so that it’s already stuck to the NK cells, and infuse them. Those also have been effective therapies.

Dr. Grover’s right. We’re still learning about how many treatments you need to get. They’re getting high response rates, but the durability is still in question. But I think that’s another exciting strategy of taking cellular therapies and bispecifics and using them together.

Dr. Grover: I think that’s the LuminICE trial, which will be open at several different sites across the country.

Sam: That’s great. That’s an important point. It’s part of the issue of Hodgkin lymphoma compared to non-Hodgkin’s. It’s not nearly as common in terms of the number of people that will qualify for these trials so that may be why there are less commonly offered.

Dr. Grover: Hodgkin lymphoma has higher cure rates and is less common. A lot of times, patients who relapse can have more aggressive disease as opposed to some other more aggressive types of lymphoma, but with Hodgkin, patients who have relapsed oftentimes can live a long time even with the disease.

I’ve seen patients in my trials who have relapsed and have not even been in remission but have been living for many, many years with relapsed disease. A lot of times, these patients may not be as sick, which is a good thing, so they’re able to travel and participate in these trials. Many of these patients may be alive and doing well even though they’re going through treatment or have some disease left.

An allogeneic transplant is still a curative option and something that we would always consider.

Dr. Stephen Ansell

Transplant

Sam: Where is all this in relation to allogeneic transplants for people who are relapsing after transplant? Allogeneic, meaning the donor is somebody else, as opposed to autologous, which is more common in Hodgkin.

Dr. Ansell: To be honest, an allogeneic transplant is still a curative option and something that we would always consider. It’s a little bit high-risk because of the potential for longer-term toxicities.

With a lot of these novel treatments, many of which have been very successful in the past, people delayed allogeneic transplants a little bit. There are some challenges now as patients are having their disease come back after standard treatment so there is a subset of patients for whom that needs to be considered. That’s a very individualized discussion between patients and their doctors to weigh the risks versus the benefits.

One of the key questions to ask is what treatment somebody got as their first line because that impacts what you would do in the second line.

Dr. Stephen Ansell

Developments in Salvage Therapy

Sam: Dr. Ansell, what are some of the developments in salvage therapy, which is given when somebody has their initial relapse?

Dr. Ansell: It’s moving pretty fast right now. Novel drugs are being used in the front line so one of the key questions to ask is what treatment somebody got as their first line because that impacts what you would do in the second line.

However, based on where most patients are right now, not very many have had an immune checkpoint treatment, which is the nivolumab and pembrolizumab that Dr. Grover spoke about. Not too many people have had that as their front-line treatment and using those in combination with standard chemotherapies, like ICE chemotherapy or GVD chemotherapy. In the majority of particularly younger patients, going to more intensive treatment and a stem cell transplant using your own cells is very much the standard management.

Some interesting recent data compared where that was used to standard chemotherapy or the use of brentuximab and chemotherapy then a transplant and then looked at outcomes. The patients with the best outcome got a PD-1 antibody before they got their transplant.

Dr. Grover touched on this, which is an important point. The PD-1 blocking antibody team seems to change the immune system a bit and make patients more sensitive to some of the chemotherapies after the fact so that’s why it seems like it makes a difference. We tend to favor chemotherapy with immune checkpoint therapy as a treatment approach before going to transplant.

We want to see people cured. Heaven forbid that it comes back the first time, but if it does, all the gloves are off. Now we’re going at it as hard as we possibly can.

Dr. Stephen Ansell

Sam: That’s interesting because I know in other cancers, people will save therapies or not want to expose them because the body will learn them. What you’re saying is that the same principle may not apply in Hodgkin. These therapies may sensitize to other therapies or make people respond better so you don’t necessarily need to leave them until later when you’ve burned through other options.

Dr. Ansell: Correct. We want to see people cured. Heaven forbid that it comes back the first time, but if it does, all the gloves are off. Now we’re going at it as hard as we possibly can and we want to utilize all the effective tools that we have so that we can truly beat it into the ground. That’s what I would recommend. Different from other cancers where you might want to string things along in a palliative approach. With Hodgkin, you want to go after it with curative intent.

Sam: It’s wild to think how quickly things evolve and how important it is for patients to seek out providers or treatment at cancer centers who have some connection with the trials and know the latest updates.

How can we advise patients to seek out that kind of care? How can they ask for that from their oncologist if they’re getting treatment in the community?

Dr. Ansell: Be an informed patient. Ask questions and be a strong advocate for yourself. There are excellent resources, like The Leukemia & Lymphoma Society, which have good information related to many of these topics. Being informed about the best way to be managed is useful.

When your doctor sees you and goes through things, asking questions relative to the information that you have helps you feel reassured that you’re on the right track. Most of us are quite okay with patients getting second opinions from other colleagues.

Second opinions help people reinforce the messages you’re already giving. People will be more comfortable doing what needs to be done if they’re hearing the same thing from more than one person. All of that pertains to a good outcome. If you ask questions, make sure you get your questions answered.

Sam: Thanks for empowering patients because it’s so hard to make these decisions even when you have a lot of resources and education. It could be such an emotional time, in addition to not feeling well, and it’s helpful to hear that you expect people to want other opinions and be informed.

Dr. Ansell: To be honest, a lot of patients come in and get so much information that it’s pretty challenging to retain them. I always tell people to bring friends or family. Have other sets of ears that can help reinforce some of the messages so that when your brain is locked down and you can’t think straight, they hear things that you might have missed.

The treatments are getting better all the time so there’s a lot of hope. I’m hoping that in the not-very-distant future, every patient with Hodgkin lymphoma can be cured with front-line treatment.

Dr. Stephen Ansell

Final Messages

Sam: Dr. Grover, can you give us some final points or takeaway messages?

Dr. Grover: I’m excited about improving earlier therapies and moving these newer therapies to the front line both to hopefully enhance cure to prevent patients from relapsing again and reduce long-term toxicities and improve quality of life.

There’s still an unmet need for patients who are refractory to PD-1 inhibitors, brentuximab, and chemotherapy. I’m hoping that over the next few years, we will have more clinical trials and more developments for that patient population.

For patients, ask questions of your provider. Don’t be shy about getting a second opinion. I’m never offended if a patient goes for a second opinion.

Sam: How about you, Dr. Ansell?

Dr. Ansell: If you’re a patient with Hodgkin lymphoma, there are unique and novel treatments that are making a big difference to patient outcomes. The treatments are getting better all the time so there’s a lot of hope. I’m hoping that in the not-very-distant future, every patient with Hodgkin lymphoma can be cured with front-line treatment.

Sam: Thank you so much for that. I remember initially being scared about death and dying. I think that’s what a lot of people think about when they hear the word cancer. Once it began to move away from that and began to become living with cancer or living life after a cancer diagnosis, I thought, I’d like to jog, paint, play guitar, hold my kids, and be able to think as well as possible.

These trials to improve quality of life while simultaneously improving outcomes are so meaningful personally. I know it means a lot to our patient population that you took the time to have this conversation with us. Thank you so much.

Dr. Ansell: My pleasure.

Dr. Grover: Thanks so much for having us.

Stephanie: Thank you so much, Sam, for being our incredible patient advocate and moderator. Also, thank you to Dr. Grover and Dr. Ansell, for the work and research you do to help move the landscape of treatment options in Hodgkin lymphoma. 

We hope that you walk away with a better understanding of the latest treatments and clinical trials in Hodgkin lymphoma. They may or may not be right for you, but our goal is to make sure you feel empowered to make a decision for yourself.

Thank you and we hope to see you again at a future program at The Patient Story.

Introduction

Stephanie Chuang, The Patient Story Founder

Stephanie Chuang: I’m the founder of The Patient Story and, more importantly, I also got a blood cancer diagnosis of non-Hodgkin lymphoma a few years ago.

We have so many shared experiences in what we’re looking for and that’s what The Patient Story is all about.

We try to help patients and care partners navigate a cancer diagnosis primarily through in-depth conversations with patients, care partners, and top cancer specialists, like the ones you’ll hear from today. 

I want to give special thanks to GSK and Karyopharm for supporting our educational program. Their support helps programs like this more available and free for our audience. But we do want to note The Patient Story retains full editorial control of this entire program. A quick reminder that this is not meant to be a substitute for medical advice. 

Our patient moderator is Ruth Fein Revell. Ruth, can you share a little bit more about your story and how you became such a passionate advocate in this space?

Stephanie Chuang
Ruth Fein and husband Danny
Ruth Fein Revell, MPN Patient Advocate

Ruth Fein Revell: Welcome, and thank you for joining us. I’m Ruth Fein, a health and science writer. I’m also a patient and a patient advocate who’s been living with a myeloproliferative neoplasm of one type or another for almost 30 years.

I was diagnosed with essential thrombocythemia when I was 38 years old and raising two young boys. I had had symptoms for many years, but they were disregarded or misdiagnosed. The most troublesome of which was severe, debilitating headaches with blind spots where I literally couldn’t work for hours at a time. I also had bone pain that I experienced for years.

What started as essential thrombocythemia transitioned to polycythemia vera and then progressed to myelofibrosis, which is where I am now. I’m very fortunate to be on a clinical trial that’s working so well that my life is wonderful. I also recognize that everyone isn’t in the same position as I am as there are a lot of people who suffer greatly from myelofibrosis.

I’m speaking with two world-renowned experts in MPNs, Dr. Raajit Rampal of Memorial Sloan Kettering Cancer Center and Dr. Gabriela Hobbs of Dana-Farber/Harvard Cancer Center. Both of you are very, very involved in the patient community and giving back through your knowledge and also taking time to do interviews like this so thank you for that.

We’ll dig into what’s been reported recently at ASH, the annual meeting of the American Society of Hematology where a lot of reports come out. Some of them are quite exciting.

Raajit K. Rampal, MD, PhD

Ruth: Dr. Rampal, give us a little bit of your background, why and how you became interested in MPNs, as well as what your practice looks at.

Dr. Raajit Rampal: I’m a physician-scientist and I lead the MPN program at MSK.

My interest came from the biology side. I’ve been working with Ross Levine for a number of years on the lab side. It became clinically interesting based on what I was learning in the lab so I’ve taken on clinical practice and doing clinical trials for patients in MPN.

This is a field with such an unmet need for effective therapies. Wanting to be at the forefront of that and trying to deliver change where it’s needed have always driven what I want to do. This was the perfect intersection of my scientific and clinical interests.

Dr. Raajit Rampal
Dr. Gabriela Hobbs
Gabriela S. Hobbs, MD

Ruth: Dr. Hobbs, would you tell us a little bit about yourself and how your interest in MPNs began?

Dr. Gabriela Hobbs: I am the clinical director of the leukemia service as well as the MPN program at Massachusetts General Hospital in Boston. I’ve always been interested in hematology as far as I can remember, and I was very fortunate to do fellowship training with Dr. Rampal.

For me, myeloproliferative neoplasms in particular are such a rewarding group of patients to take care of. It merges everything that I love about being a physician. I can have very longitudinal as well as very intimate patient relationships with the patients whom I take care of. From the clinical perspective, I found taking care of patients incredibly rewarding and also very varied.

From the scientific perspective, when I was an undergraduate student, we started seeing some of these oral-targeted agents being approved and I knew that was something I wanted to be involved in for my career.

Being a clinical investigator who’s able to see clinicians like Raajit Rampal doing investigations in the lab, finding new targets and new drugs, and being the person who helps take that to clinical trials to the patients is incredibly rewarding.

The most common symptom of patients with myelofibrosis is fatigue, which is probably one of the reasons why myelofibrosis and the other MPNs sometimes take a while to get diagnosed.

Dr. Gabriela Hobbs

Symptoms of Myelofibrosis

Ruth: Myelofibrosis is rare. Some practitioners don’t see very many MF patients. Some patients who are diagnosed with myelofibrosis don’t have enough information or are misguided at times. What do you each see as the major symptoms of myelofibrosis?

Dr. Hobbs: Myelofibrosis is a disease that can present in many different ways. I certainly see completely asymptomatic patients. Their doctor noticed that they had some abnormalities in their blood counts or maybe the patient themself noted that their abdomen felt a little bit different. Patients are on the spectrum of either not having a lot of symptoms or having lots and lots of symptoms.

I would say the most common symptom of patients with myelofibrosis is fatigue, which is probably one of the reasons why myelofibrosis and the other MPNs sometimes take a while to get diagnosed. Other symptoms that we see a lot of are itching, night sweats, fevers, and unintentional weight loss.

Dr. Rampal: Part of the challenge is whether those symptoms are communicated in visits with physicians. Part of that involves us asking the right questions or, at least, training our colleagues to ask the right questions because not everybody is forthcoming about their symptoms. The alternative is that they get so used to their symptoms that it’s the new normal for them and that is sometimes the tougher part of trying to understand how somebody is doing.

Dr. Hobbs: Occasionally, there may be some patients who feel like there are certain symptoms that they wouldn’t bring up to an oncologist. When I meet a patient for the first time and go down my checklist of MPN symptoms, I’ll ask them about itching and they’d say, “How did you know?” We’re fortunate in the MPN world to have these forms that have been validated to help us ask about symptoms that we know are very common in patients with MPN so that we don’t miss anything.

There’s a whole spectrum of symptoms patients can experience.

Dr. Raajit Rampal

Dr. Rampal: Myelofibrosis is a disease of the bone marrow where you have mutated cells that start to grow and take over the bone marrow. They cause inflammation and we think the inflammation causes scarring in the bone marrow. As that happens, the bone marrow starts to contract and is unable to make blood cells. Blood cells start to go into the liver and the spleen to try to produce blood so those organs get larger and cause symptoms.

The inflammation that causes the scarring and damage in the bone marrow also causes people to have symptoms. Those include getting fatigued, losing weight unexpectedly, and having bone pain and aches. There’s a whole spectrum of symptoms patients can experience, but those are among the most common.

That’s how we think about myelofibrosis and how we think about the disease getting worse. We look at blood counts. If people’s blood counts are getting worse, that’s a sign of disease progression. If their spleens or livers are getting larger or they’re feeling worse, all of those are signs of the disease progressing.

There were two phase 3 studies presented about myelofibrosis, the navitoclax and pelabresib studies.

Dr. Gabriela Hobbs

ASH 2023 Updates on Myelofibrosis Treatments

Ruth: We all know there’s been such an explosion in advances in myelofibrosis in recent years. Dr. Hobbs, what came out of ASH 2023 that you’re most excited about?

Dr. Hobbs: It’s exciting. I can’t remember participating in an ASH conference where there were two phase 3 studies presented about myelofibrosis, the navitoclax and pelabresib studies. That in and of itself was a reflection of how far the field has come. We’re now presenting phase 3 studies on drugs that may get approved.

Dr. Rampal: I totally agree. When have we had two phase 3 studies read out? I can’t remember if that’s ever even been the case simultaneously. Thinking about this in the context of our patient audience, this is a clear sign of progress in the field.

Let’s separate that idea from what happens from a regulatory standpoint. You have to get to this point. This is where the finish line is. It is incredibly encouraging that we’ve got drugs to this point of phase 3 where we may have definitive results that could lead to approvals.

What we can probably say, at least with both drugs, is that they have activity in the disease. There’s no question. What happens from here, of course, is up to the FDA. But I’m encouraged by this. I think these drugs have the potential to make a difference for patients so this is exciting.

The combination (ruxolitinib and navitoclax) led to a very dramatic improvement in spleen volume reduction in patients compared to patients who were treated with ruxolitinib alone.

Dr. Gabriela Hobbs

Dr. Hobbs: Both of these studies were phase 3 studies, as Dr. Rampal mentioned. The navitoclax study was the TRANSFORM study that compared ruxolitinib alone to ruxolitinib and navitoclax. They wanted to see if the combination of the two drugs was more effective at improving spleen volume response as well as improving the symptoms of myelofibrosis patients.

They found that the combination led to a very dramatic improvement in spleen volume reduction in patients compared to patients who were treated with ruxolitinib alone. The symptom endpoint was more difficult, as it seemed like symptom improvement was similar with the combination of navitoclax and ruxolitinib compared to ruxolitinib alone.

My take on that is it’s not entirely surprising that a drug like navitoclax would not improve the symptoms, but it certainly didn’t make patients feel worse. I think that’s important when you think about combination therapy as well. I wouldn’t consider that an entirely negative endpoint.

Why should patients care about how big the spleen is and how much it shrinks? That is one of the few things we know that correlates with survival.

Dr. Raajit Rampal

Dr. Rampal: Let me build off of something that Dr. Hobbs said. Symptoms are important to patients and that has to be part of any of our treatment arsenals. But as you said, we want to get drugs that alter the trajectory of the disease and not simply focus on symptom reduction. That has to be part of the conversation going forward as we think about new drugs in this space.

How much weight do we put on symptom reduction as something that we, as a community or the FDA, should fixate on? As long as the drug is not making people feel worse, if it’s doing other things for patients, then maybe that’s where the win is if you will.

About pelabresib, this is a study of the combination of pelabresib, which is a BET inhibitor, plus ruxolitinib versus ruxolitinib alone. The study looked at whether patients had a greater degree of spleen shrinkage with the combination or ruxolitinib alone.

The answer was unequivocally yes. Patients who got the combination had a much greater spleen response, 65% versus 30%.

Why is that important? Why should patients care about how big the spleen is and how much it shrinks? That is one of the few things we know that correlates with survival. We’ve known from the time of ruxolitinib. Spleen shrinkage correlates with overall survival, which is something we all care about deeply.

There was a trend toward the symptoms getting better with the combination. It wasn’t quite statistically significant, but it was certainly a trend that favored the combination.

Importantly, it didn’t add toxicity. We didn’t see that there were any new major signs of toxicity with the two drugs versus one. In oncology, we worry about that all the time. If you add another drug, you may add toxicity, but that wasn’t the case here. From that standpoint, I’m very encouraged by both data sets.

A big takeaway from having all these drugs is that we shouldn’t wait for people to get that sick. We should treat earlier on.

Dr. Raajit Rampal

Treatment Sequencing

Ruth: Dr. Rampal, as we talk about more options available both today and in the future, one of the things that comes up often, especially for higher-risk MF, is sequencing. What are we learning about optimizing the new drugs and combination drug therapies, including determining when and how to switch therapies?

Dr. Rampal: The answer is we don’t know. The broader context of this is that we have more options so that has two implications.

Historically, there’s been a reluctance to start therapy because you didn’t have anything else. If you were in a world where there was only ruxolitinib and it stopped working, what were you going to do? That’s not true anymore.

A big takeaway from having all these drugs is that we shouldn’t wait for people to get that sick. We should treat earlier on. What is earlier on? There’s some ambiguity there, but I think that is one of the implications of having a lot more drugs.

The reality is we’re going to learn how to use these drugs as we go along. There isn’t a great deal of data. We have data on switching from ruxolitinib to fedratinib. We know what happens and how people do when you do that, but do we have data for the other drugs?

If we start going from momelotinib to ruxolitinib, we don’t have the granular data for that. Those are things we’re going to figure out in practice, probably over the next 1 to 2 years, I’d say.

Now that we have four approved JAK inhibitors, there’s no reason to feel like somebody needs to wait for symptoms from their spleen or their disease.

Dr. Gabriela Hobbs

Dr. Hobbs: The point that Dr. Rampal made is so important, especially when we think about what he said about one of the things that we know in myelofibrosis, which is a smaller spleen equals better outcomes.

An important message for patients is exactly what Dr. Rampal said. Now that we have four approved JAK inhibitors, there’s no reason to feel like somebody needs to wait for symptoms from their spleen or their disease because we do have a lot of options.

Now that we have a lot of options, it became a situation where all of us are calling each other and asking, “How do you switch from this one to the other? Have you had a good experience?”

Sometimes, the clinical trials don’t necessarily translate to what we do in clinical practice. Many clinical trials require that patients be completely off of a JAK inhibitor before they switch to the other, which is something that, in practice, probably neither of us would ever really feel like doing. Over the next year, it’s something that we’re going to have some publications about to help guide the broader community to do that safely.

What these data have shown with the FREEDOM trials is that you can better manage gastrointestinal toxicity and that it does get better over time.

Dr. Raajit Rampal

ASH 2023 Updates on Fedratinib

Ruth: Dr. Rampal, what did we learn about fedratinib at ASH 2023?

Dr. Rampal: The most updated data was the FREEDOM2 study, which looked at fedratinib in patients who have been on ruxolitinib. There were earlier trials that looked at the same question, like the JAKARTA2 trial.

When fedratinib was being studied early on, it was seen that there was a lot of gastrointestinal toxicity, like nausea, vomiting, and diarrhea, which was experienced by the majority of patients.

There have been two subsequent trials with fedratinib, the FREEDOM trials, where they aggressively tried to manage the symptoms from the get-go. They didn’t wait for people to get sick or have nausea or diarrhea. When they prescribe the drug, they say, “When you start the drug, if you start to feel nausea, you’re going to take this medication or if any diarrhea starts, you’re going to take this medication.” You don’t let these symptoms get out of control.

What these data have shown with the FREEDOM trials is that you can better manage gastrointestinal toxicity and that it does get better over time. Is that still a side effect that we have to be concerned about? Yes, but it is something that we can manage in most cases if we’re aggressive about doing that upfront and the expectation is that it will get better over time.

The data (on selinexor) is still in earlier stages so I’m waiting to see if this agent is well-tolerated by patients.

Dr. Gabriela Hobbs

ASH 2023 Updates on Selinexor

Ruth: Dr. Hobbs, what about selinexor?

Dr. Hobbs: Selinexor has been interesting as well. This is a newer agent that we’ve started to see some preliminary results on and they presented their data also in combination with ruxolitinib. This agent seems to have very impressive responses in terms of shrinking the spleen and improving symptoms as well.

The data is still in earlier stages so I’m waiting to see if this agent is well-tolerated by patients. We’ll have to see how the later studies will pan out, but it’s still exciting.

Having this fourth agent will be very helpful in the management of patients with MF, especially patients who have anemia and aren’t able to get a bone marrow transplant.

Dr. Gabriela Hobbs

ASH 2023 Updates on Momelotinib

Ruth: There’s an unmet need for the treatment of anemia for patients with MPN, specifically myelofibrosis, which brings us to momelotinib and a few others.

Dr. Hobbs: We’ve mentioned that there are now four JAK inhibitors that are approved for the treatment of myelofibrosis. We have pacritinib, ruxolitinib, fedratinib, and momelotinib, which was approved at the end of September 2023.

Momelotinib is a JAK inhibitor that was approved a little bit differently than the others. Its main indication is for patients who have myelofibrosis and anemia. Anemia has been an unmet need in the management of myelofibrosis so it’s exciting to have a drug like momelotinib that can help anemia and also a drug like pacritinib that can also help anemia in a subset of patients.

In my practice, I’ve noticed that since the approval of this agent, there have been many patients, especially those who are active online, in their communities, and in patient advocacy organizations, who have been excited or eager to switch to this medication.

I do think that having this fourth agent will be very helpful in the management of patients with MF, especially patients who have anemia and aren’t able to get a bone marrow transplant.

When we have patients with myelofibrosis who have anemia, it’s important to consider if a bone marrow transplant is the right therapy. But for those who can’t receive that therapy, momelotinib takes care of a lot of the parts of the disease that we worry about, like the symptoms, the spleen, and the low red blood cell numbers.

In some cases, they take patients who are relying on transfusions and convert them to not needing a transfusion, which is important in terms of survival.

Dr. Raajit Rampal

Dr. Rampal: There is so much going on in anemia in this disease, it’s remarkable. It’s a problem for which we had no good solutions until very recently.

As you mentioned, momelotinib and pacritinib also seem to have an effect in a proportion of patients where they can increase the hemoglobin. In some cases, they take patients who are relying on transfusions and convert them to not needing a transfusion, which is important in terms of survival.

We know that that correlates with survival, but it’s also quality of life. If you have a patient who’s getting stuck in the transfusion chair for 4 to 6 hours a week or more and that is no longer an issue, that is immensely important to their quality of life. It’s an important problem.

There are some other drugs in development and that includes a drug called luspatercept, which is FDA-approved for myelodysplastic syndrome. There are also some other drugs from a few other companies that are anemia-specific and there was some data presented at ASH on them. There are early signs of efficacy. Too early to say anything definitively, but at least it looks like these are drugs that will be studied further.

What’s been practice-changing is having the approval of the last JAK inhibitor, which is momelotinib.

Dr. Gabriela Hobbs

Practice-Changing Updates

Ruth: We talked about what’s happened in the lab, what’s in the drug approval process, what’s recently been approved, and where our needs still are. What came out of ASH that you think is truly practice-changing immediately or in the near future?

Dr. Hobbs: What was very exciting was seeing the two phase 3 studies. Although those two drugs, pelabresib and navitoclax, are still not approved, they are potentially closer to our doorstep and something that we will have to have conversations about how to use.

Do we use them in combination with the JAK inhibitor that they were studied with? Do we use them with other JAK inhibitors? How do we think about sequencing when we’re talking about combination? Although neither of these agents is approved, these are questions that need to be discussed.

What’s been practice-changing is having the approval of the last JAK inhibitor, which is momelotinib. We now have four drugs that we can prescribe to our patients when we see them in the clinic, especially those who have anemia.

There are so many drugs coming down the pipeline and showing interesting activity, especially some of those showing activity by themselves.

Dr. Gabriela Hobbs

Personalizing Myelofibrosis Treatment

Ruth: The drugs and the studies we’ve talked about are all very exciting, but what other treatments are you excited to share with patients to help you personalize treatment?

Dr. Hobbs: We’ve discussed the MANIFEST and TRANSFORM studies looking at combination studies in phase 3. There are so many drugs that are being evaluated and it’s been very exciting to be at an ASH where we hear about so many different mechanisms of action being explored. Many of those are by themselves and some of them are now getting to the point where they’re used in combination.

To mention a few, there was a compound called a PIM1 kinase inhibitor, another one that inhibits lysyl oxidase, which is a group of enzymes that have to do with making fibrosis or scarring happen in the bone marrow, and an LSD1 inhibitor called bomedemstat.

There are so many drugs coming down the pipeline and showing interesting activity, especially some of those showing activity by themselves. Generally speaking, when we have new drugs that are not JAK inhibitors used by themselves, we rarely see a lot of clinical activity so I thought that that was exciting.

Individualized medicine is the holy grail and there’s a lot of different ways to think about it. There’s how we use the drugs we have now and what some of the newer drugs may be able to do for us.

Dr. Raajit Rampal

Dr. Rampal: There is this whole pipeline of things coming forward, which is amazing for this field. We spent some time talking about the top-line phase 3. But as Dr. Hobbs mentioned, there are all of these drugs that are in early development that are showing us that they may be able to do something. Even beyond what we have, some things are part of the big picture here.

Individualized medicine is the holy grail and there’s a lot of different ways to think about it. There’s how we use the drugs we have now and what some of the newer drugs may be able to do for us.

A key example of this is calreticulin. There’s been a focus on this. There are drugs in investigation that are specific antibodies that target calreticulin. That could be a game-changer if those things work. Pre-clinically, there’s good rationale. Imagine a future where if those drugs are effective, then for calreticulin-mutant patients, this is what we use. We have a drug that targets your mutation. That is where we want to be.

Of course, other mutations occur in the disease and we’ve already started trying to do personalized medicine for patients. Some patients have an IDH mutation that occurs typically in people with more advanced diseases.

We’ve completed a trial where we used a JAK inhibitor plus an IDH inhibitor. IDH inhibitors are FDA-approved for people with leukemia and we’ve combined those drugs and seen very good results. That’s an example of genetically-informed personalized medicine, but there’s also how you use the drugs we have in practice.

Dr. Hobbs: We’ve mentioned a few times that we have four different JAK inhibitors and it’s important to know which patients those are going to help. Are there certain situations where we should use one JAK inhibitor versus another?

At ASH 2023, we saw an update on a similar study that was published recently by the folks who looked at pacritinib. They found that patients who have a symptom improvement of greater than 10% had an improvement in survival, which is similar to what they showed recently with patients on pacritinib having a survival benefit if they also had a spleen volume reduction.

Again, that goes to the theme that we were saying. It’s important to use these drugs and make sure that those drugs are doing what they’re supposed to be doing for the patient. We have endpoints that help patients not only to live better but hopefully to live longer. That can also help the practicing doctor to say this drug is not meeting those endpoints. It’s not helping my patient have an improvement in their spleen or their symptoms. We have other drugs that we should we should think about switching to.

One of the areas where there’s a lot of interest is looking at pre-fibrotic myelofibrosis or early myelofibrosis to see if we can get to the disease earlier before a lot of scarring develops.

Dr. Gabriela Hobbs

ASH 2023 Updates on Interferon

Ruth: There was an interesting study presented at ASH about interferon-α versus hydroxyurea, which is the oldest of the drugs still used for myelofibrosis or MPNs. This study was in untreated MPN patients who were unable to take ruxolitinib. What did we learn?

Dr. Hobbs: Several abstracts were presented with interferon. One was the updated results of the DALIAH study comparing pegylated interferon to hydroxyurea for patients with earlier disease essential thrombocythemia and polycythemia vera. There was also another study looking at earlier myelofibrosis, like pre-fibrotic myelofibrosis.

There’s been a lot of interest in looking at interferons in general across the spectrum of the disease. One of the areas where there’s a lot of interest is looking at pre-fibrotic myelofibrosis or early myelofibrosis to see if we can get to the disease earlier before a lot of scarring develops.

If we look at all the characteristics of the patients who had stable disease for years versus those who progressed, is there a difference that AI can say if you look at these particular parameters, this is a warning sign?

Dr. Raajit Rampal

Artificial Intelligence in Hematology

Ruth: There was a fascinating presentation on the use of artificial intelligence, specifically to differentiate between essential thrombocythemia and pre-fibrotic primary myelofibrosis. Is that something that you see coming into practice or are we way off on that?

Dr. Rampal: We’ll level set by talking about what we mean by AI, which neither of us are experts in. One of the powers of AI is to take broad sets of data and identify patterns. That is a very simplistic way of thinking about the many things that AI can do and is built to do. It can take thousands of variables and find patterns that humans aren’t going to be able to find in real time.

This is an example of what you’re talking about. If you took thousands of bone marrow samples and you said that clinically, these people look like ET, but based on the other parameters that we have, these people look like myelofibrosis. Is AI going to be able to better discriminate versus a human and say this pattern better fits the ET pattern and that pattern better fits the MF pattern?

It will help us refine some of the key characteristics of the disease. The hope is that it may also give us some clues for things like progression if you look at the pattern of a lot of patients. We’re talking about thousands of patients and if we look at all the characteristics of the patients who had stable disease for years versus those who progressed, is there a difference that AI can say if you look at these particular parameters, this is a warning sign? That I think is part of where we think this is going to go.

There are lots of great resources online where, as a patient, you can advocate for yourself to recommend different treatments to your provider to make sure that you’re getting the most updated care.

Dr. Gabriela Hobbs

How Patients Can Be More Proactive in Their Treatment

Ruth: Now that we’ve heard updates out of ASH 2023, what can a patient bring to their community hematology-oncologist as opposed to waiting for it to trickle down? What are some of the ways that a patient can be more proactive with knowing what we now know?

Dr. Hobbs: If you’re a patient or a family member of a patient, you’re already taking those steps that are so important. It’s important to remember that myeloproliferative neoplasms are rare diseases so not everybody has access to subspecialized care.

What’s incredible about the MPN community is that the group of clinicians who treat MPN and are doing research in MPN are extremely committed and passionate about treating these diseases. We’re excited to work with industry partners who are similarly very passionate about finding new therapies for these diseases.

There are lots of great resources online where, as a patient, you can advocate for yourself to recommend different treatments to your provider to make sure that you’re getting the most updated care.

It’s worth asking your physician: when is it time for me to get started on treatment? If you are at the point of needing treatment, it may be worth getting a consultation in a center where there’s a lot of experience.

Dr. Raajit Rampal

Dr. Rampal: If you’re a patient who’s being cared for in the community, it’s worth asking your physician: when is it time for me to get started on treatment? This is an evolving space. We’re more and more convinced that earlier may be more beneficial, but there is a danger in waiting too long.

If you are at the point of needing treatment, it may be worth getting a consultation in a center where there’s a lot of experience. We, who are focused on this, have the forefront of the developments at our fingertips. Doctors in the community setting are busy seeing a lot of different types of cancers. They have to keep up on all of this and they may not have immediate access to that information.

If it is time to get treated, it may be worth a consultation at least to say, “Is this the right thing? Or is there a compelling clinical trial that maybe may make more sense right in the current era?”

We’re bringing back hope. We’ve seen more developments at ASH 2023 than in maybe any prior in the last ten years that I can think of. That’s not unimportant.

Ruth: That’s a very hopeful message. We seem to say that every year but maybe now even more than ever.

Conclusion

Ruth: From a patient perspective, one of the themes that came out of ASH 2023 is all these new approaches to old diseases. It’s not that we’ve discovered new diseases. It’s that these are diseases and patients who have not had solutions for so long or our options have been so limited and now there are more and more options.

Thank you both so much for your time, Dr. Hobbs and Dr. Rampal. Always my pleasure.

Stephanie: Thank you so much, Ruth, for being our incredible patient advocate and moderator. Also to Drs. Hobbs and Rampal for the work and research you do to help move the landscape of myelofibrosis options. 

We hope that you walk away with a better understanding of the latest treatments and clinical trials in myelofibrosis. They may or may not be right for you, but it is our goal to make sure you feel empowered to make a decision for yourself.

Thank you and we hope to see you again at a future program at The Patient Story.

Introduction

Stephanie Chuang, The Patient Story: Hi, everyone! Welcome to the program hosted by The Patient Story and The Leukemia & Lymphoma Society.

I had a different blood cancer, non-Hodgkin lymphoma, and I went through treatment a few years ago, but I’m so passionate about these discussions. So many things are happening in the landscape of changing treatment options and they start with clinical trials.

We hear about clinical trials but the term is so daunting and overwhelming. Our goal is for you to have a much better understanding of what they are in human terms. Maybe some might be right for you that you can ask your own doctors about.

The Patient Story features hundreds of in-depth, authentic patient stories across cancers and we also feature top cancer specialists. Our goal is to humanize cancer and help you navigate life after a diagnosis, whether you’re a patient or a caregiver. You can join our community and you’ll get first access to programs like these with new updates and new stories.

We’re so proud to be co-hosting this with The Leukemia & Lymphoma Society. It is the world’s largest nonprofit health organization dedicated to funding blood cancer research as well as offering patient services and education.

They have great resources if you haven’t checked them out yet. Their information specialists are just a phone call away to help you answer some cancer questions. They also offer help to pay for cancer costs through a co-pay assistance program, like travel to CAR T-cell therapy or clinical trials.

The Latest in Myelofibrosis Treatments - Clinical Trials
Dr. John Mascarenhas

Stephanie: First up, really lucky to have Dr. John Mascarenhas, professor of medicine at the Icahn School of Medicine at Mount Sinai, director of the Center of Excellence for Blood Cancers and Myeloid Disorders, director of the Adult Leukemia Program, and also leads clinical investigation within the Myeloproliferative Disorders Program.

Dr. Mascarenhas, really appreciate you being here. I heard you describe yourself as being tireless and working nights and weekends to help patients in this space. We really want to understand what drew you to MPNs and to continue to do this work for patients.

Dr. John Mascarenhas: Thanks for having me join you. My interest began in the laboratory doing leukemia research many years ago. It evolved over time into clinical research in which I was introduced to MPNs and I really gravitated towards it. This was at a point where we didn’t have JAK inhibitors.

I was at the right time when the discovery of the JAK2 mutation came out. I got involved in the early development of JAK inhibitors and watched the field blow up. It’s been really exciting and rewarding to see this transition from how we used to treat patients with myelofibrosis and other related MPNs to what it looks like today so I’m very enthusiastic and optimistic about the future.

Stephanie: Thank you, Dr. Mascarenhas. We know that the landscape has shifted very quickly in a short amount of time. Excited to talk about it.

The Latest in Myelofibrosis Treatments - Clinical Trials
Dr. Tanya Jain

Stephanie: We’re also really excited to have Dr. Tanya Jain here tonight, another MPN specialist. She is an assistant professor of oncology at Johns Hopkins Medicine and director of the Adult CAR-T Cell Therapy Program at the Sidney Kimmel Comprehensive Cancer Center with myeloproliferative disorders as a top area of interest and studying newer drugs in the early phase of development.

Dr. Jain, thank you for joining our discussion. We’d also love to understand what drew you to the MPN space. What’s the driver of doing this work for patients and their families?

Dr. Tania Jain: Thank you so much for having me. I’m absolutely delighted to be a part of this panel.

I don’t think it was a specific event. It was a natural transition during my fellowship under the mentorship of Dr. Ruben Mesa and Dr. Jeanne Palmer, who’ve obviously done a lot of work and continue to do so.

How that transitioned me was to recognize the significant unmet need in the space and the opportunity that existed to contribute to improve outcomes for patients and to improve the lives of patients and their families so that’s what we try to do.

Stephanie: Thank you so much. That means a lot for all of us who’ve gone through cancer.

The Latest in Myelofibrosis Treatments - Clinical Trials
Ashley Giacobbi

Stephanie: Speaking of incredible work, we have Ashley Giacobbi representing The Leukemia & Lymphoma Society’s Clinical Trial Support Center. It’s a really great resource because as we know, clinical trials can be very daunting and seem like a lot to wade through.

Ashley, thank you for being here. I have such a special place in my heart for nurses. I remember going through my treatment and nurses being such a lifeline so I really appreciate the work that you do. We’d love to understand more about yourself and what drew you to this calling.

Ashley Giacobbi: Thank you so much. I’m really honored to be here.

I have been a nurse for almost 20 years now and have enjoyed all of my time at the bedside.

I get extra excited when talking about new changes and how much has changed in the world of oncology over the last 20 years. It’s exciting to be able to help patients find clinical trials when they’re seeking the newest and next level of care and some of these new developments and advancements that we’ve had.

Stephanie: Thank you, Ashley. We’ll be talking about some of the top topics you’re getting from patients and care partners who are calling you and asking for your help in the clinical trial space.

The Latest in Myelofibrosis Treatments - Clinical Trials
Mary Linde

Stephanie: Finally, we’ve got Mary Linde, who I’m really blessed to be able to call a friend now. Mary, you’re a myelofibrosis patient advocate. You lead a group on Facebook with myelofibrosis patients and care partners. We’re so lucky to have you share your perspective as well. Can you describe yourself a little bit outside of cancer? As we know, we are so much more than a diagnosis.

Mary Linde: Thank you for that. I’m almost 61 years old. I’m a nurse as well and have both a bachelor’s and a master’s degree in nursing. I stopped clinical nursing for 25 years.

I’m currently the CEO of a small nonprofit foundation that mostly runs a retirement community here in San Francisco. I have always had a heart to serve the elderly.

I’m a mom to two amazing adult sons who are launched and living on their own. One is married and one is about to get married. I’m really hoping for grandchildren soon and to live long enough to really enjoy those grandchildren.

I have a three-year-old Coton de Tulear puppy who gets me out and moving. I walk 3 or 4 miles a day with him.

The Latest in Myelofibrosis Treatments - Clinical Trials

Mary’s myelofibrosis diagnosis

Stephanie: Like so many of us experience, a diagnosis changes our lives. What led you to figure out that something wasn’t right and how did you get your primary myelofibrosis diagnosis?

Mary: It wasn’t easy. I was about 54 1/2 when I started with vague symptoms. I had fatigue, dizziness, and sometimes vertigo to the tune of whoosh and then I fell. I felt like I needed to nap more frequently. I felt like if I walked up any incline, I needed to rest.

I knew something was wrong. I thought I had mono or Lyme disease. I kept complaining to my primary physician about these symptoms. He kept telling me I had menopause, which had long been through at that point.

I would repeatedly go back to my primary physician and say, “Please, let’s investigate what this is,” and even told him that my father had a rare blood cancer at around this same age.

Finally, six months into begging, I reached out my arm to the doctor and said, “I’m not leaving your office till you do a chem 7 and a CBC,” and he did.

Three days later, I got the results that I had platelets in the 800,000. Of course, Google became my friend. I called the doctor and he refused to talk to me. He said, “I’m sending your blood off for special testing. I don’t want to tell you because I don’t want to scare you.”

I started Googling and I was pretty certain I had an MPN. Three months later, I found out that I had the JAK2 mutation. I didn’t find out from my primary care physician; I found out when I got a call from the oncology center admitting me to services.

When I walked into the oncology center, I had a very strange experience. The introductory oncologist said to me, “I know you’re probably really afraid of the C-word so we’re not going to talk about it. Let’s talk about it like a blood disease.” I told her that I was a nurse so she didn’t have to do this. Then she said, “The other C word is an evil drug so we’re not going to talk about that either.”

I kindly asked her to get me another doctor and then sought a second opinion. At that time, I wasn’t so afraid of dying as much as I was afraid of not having the information I needed to live well. I didn’t know if my life was going to be shortened and I wanted as much information as I could get.

Stephanie: I really appreciate you sharing all that, Mary. I also love the message of self-advocacy and empowerment. It’s your life, you know your body, and you certainly didn’t let that fall through the cracks.

The Latest in Myelofibrosis Treatments - Clinical Trials

What is myelofibrosis?

Stephanie: Dr. Jain, what is myelofibrosis in layman’s terms? What are some of the more common first signs or symptoms?

Dr. Jain: What we heard from Mary’s story is something that I hear in the clinic fairly commonly. Having that fatigue and tiredness is something that often takes people to physicians to get tested. Delays are not uncommon either because fatigue or tiredness have several possible reasons. Some may be more common than others.

Mary also mentioned the JAK2 mutation, which is of relevance here. The premise of myelofibrosis starts with the overactivation of the JAK/STAT pathway, which is supposed to be a normal functional pathway that’s supposed to do regular stuff and make blood cells.

When it’s over-activated or activated without any restrictions, that’s when undesirable things happen, which can include affecting the bone marrow function in a negative way.

You could be making too many cells or you could alter the bone marrow function in the way that there is more scarring in the bone marrow, which is the fibrosis in the term myelofibrosis, which again affects the ability of the bone marrow to function normally whose job is to make a normal quantity and quality of blood cells.

As a result, patients can get anemic or have low hemoglobin, which can cause tiredness, fatigue, difficulty breathing, and related symptoms.

By virtue of the JAK/STAT pathway activation, this systemic or generalized inflammation that we often notice or patients leads them to a workup. What that results in is what we in our clinic call constitutional symptoms or symptoms that could be nonspecific or vague as sometimes labeled.

Those can include things like night sweats, low appetite, or other symptoms resulting from an enlarged spleen like abdominal discomfort, which are other symptoms that can sometimes lead to further investigations clinically.

Stephanie: Thank you. I know that’s a lot to cover in a short amount of time. We do hear lots of stories about how long it can take to figure out a myelofibrosis diagnosis so that’s not unique to Mary’s situation.

Landscape shifts in myelofibrosis treatments

Stephanie: Dr. Mascarenhas, you alluded to how optimistic you are because there are so many developments happening. How would you describe the landscape shifts that have happened in myelofibrosis treatments, especially in just the last few years?

Dr. Mascarenhas: Myelofibrosis is a stem cell-derived blood cancer and it could affect people in different ways. You don’t meet two people that walk the same path. They all come in different forms and fashions. Their clinical picture can be really varied and their course can be quite heterogeneous and variable, too. You have to understand the patient that you’re dealing with and the patient-specific goals of therapy.

For some patients, it could be alleviation of anemia. For other patients, it could be systemic symptoms like fevers, night sweats, weight loss, bone pain, and profound fatigue that can be quite debilitating. For many patients, it can be an enlarged spleen or liver that’s causing a lot of discomfort and challenging normal activities like bending over and doing things that would be normally easy to do.

Knowing how the disease is affecting the patient really informs and dictates how best to approach the patient. It’s typically trying to alleviate the symptomatology and reduce the spleen, and that’s usually using JAK inhibitors.

JAK inhibitors

Dr. Mascarenhas: Over the years, we’ve grown to have three clinically or commercially available JAK inhibitors: ruxolitinib since 2011, fedratinib since 2019, and pacritinib since 2022. And a fourth one, momelotinib, later in 2023.

This provides a lot of opportunities to try to address those symptoms. Those cytokine-driven symptoms that Dr. Jain explained are a result of this JAK/STAT pathway. These drugs are great in reducing a lot of that inflammatory cue that makes patients feel terrible, improving their sense of well-being and functionality, and reducing their spleen.

In doing so, patients have a better quality of life and, by virtue in most cases, will live longer because they can do the simple things that we need to do. They can move and eat. People who move and eat will simply live longer and do better than patients who cannot and that’s just generally true in oncology.

They have really revolutionized the quality of life aspect. As Dr. Jain pointed out, she worked with Dr. Mesa who was really instrumental in measuring quality of life and making that an endpoint for clinical trials and bringing attention to symptomatology and quality of life.

We have a great armamentarium that covers lots of different types of patients to improve their symptoms and quality of life.

We are developing drugs that are looking to try to improve anemia. Historically, we use drugs like epoetin alfa or darbepoetin alfa, which are erythropoiesis-stimulating agents, to try to improve hemoglobins, get patients out of the transfusion suite, and give them some more energy back, or drugs like danazol, a synthetic male androgen.

There are drugs that we repurpose, which is a common theme in oncology, from other diseases like multiple myeloma. We use drugs called IMiDs or immunomodulatory drugs like thalidomide, lenalidomide, or pomalidomide. These can all be used in myelofibrosis off-label to improve hemoglobin with responses of about 20 to 30%.

The reality is we can improve hemoglobin in some patients, we can improve symptoms in the spleen, but there’s still really a lot left to do.

How JAK inhibitors work

Mary: Dr. Mascarenhas, could you tell us how JAK inhibitors work? What are their benefits and limitations?

Dr. Mascarenhas: JAK inhibitors are a class of agents interestingly invented in the setting of this disease and now have applications to a lot of different diseases that are not even malignant.

They intermittently reduce the JAK/STAT pathway that is inappropriately activated in the bone marrow cells. This pathway is responsible for causing the proliferation of blood cells and elaborating inflammatory mediators.

JAK inhibitors intermittently quell this cascade of events. That reduces the propensity to have this inflammatory state, this overproduction of blood cells, and seems to improve symptoms by reducing cytokines, which are inflammatory byproducts.

Patients feel better and can move and eat. It restores vitality for reasons that I personally don’t understand and I’ve never seen a good explanation for.

It also reduces the spleen. It’s a phenomenon I don’t really understand. It’s an interesting aspect of the drug. It reduces symptoms by reducing the activity of this pathway.

Unfortunately, these drugs don’t induce remissions. They don’t kill what I would call the maternal stem cell that gives rise to all of these abnormal cells. It doesn’t get rid of that cell.

It quiets down what’s happening in the bone marrow and the spleen allows for some degree of normalcy. The malignant cell population still remains in the body, in the bone marrow, and in the organs.

Unfortunately, we don’t see changes in the bone marrow that would lead us to believe that we’ve remitted the disease. Myelofibrosis is in the name. You have scarring in the bone marrow that typically remains even while patients enjoy the clinical benefits of the drug.

The Latest in Myelofibrosis Treatments - Clinical Trials

Then there’s the potential for downsides of the drugs. They often will exacerbate cytopenia or low blood count. Anemia and thrombocytopenia (low hemoglobin and low platelet) count can often get lower with these drugs.

We’ve pivoted to try to develop drugs that may not be as myelosuppressive, as count reducing and may even improve some of the blood counts.

Pacritinib can be delivered in patients with low blood counts and can improve hemoglobin in about 25% of patients. Momelotinib has also been associated with improvements in blood counts.

What we now know, which we didn’t know when we started off in all of this, is these drugs are not just JAK inhibitors. They interfere with a lot of different pathways that may be relevant and irrelevant and cause toxicity.

For example, inhibiting ACVR1, which is another pathway that’s important for iron availability, might explain why pacritinib and momelotinib improve hemoglobins and why maybe ruxolitinib and fedratinib.

There are a lot of nuances with these drugs that help us understand why they may fit niches and help certain people in certain ways and why you can provide serial JAK inhibitors.

If you fail one, it doesn’t necessarily mean that you wouldn’t enjoy some response to another. You can go from one to the other. The tailoring of the JAK inhibitor is somewhat of an art more than a science in some cases and requires knowing the patient, what the goals are, and trying to match the potential goals and potential toxicities to that patient.

Mary: Thank you for that. I’ve often heard that we’re not getting rid of our JAK2 but maybe turning the volume down on it a bit with the use of these drugs.

The Latest in Myelofibrosis Treatments - Clinical Trials

Determining the sequence of treatment

Mary: Dr. Jain, how do you know which JAK inhibitor might or might not work and which one to try first for a patient?

Dr. Jain: I’m going to piggyback on what Dr. Mascarenhas said and emphasize the point that no two patients with myelofibrosis will be the same. Everybody will have their own presentation or different things that you need to address.

Everybody will have a different trajectory in terms of their disease course and that’s what’s important to recognize as you’re thinking about what you’re going to start a patient on in terms of your choice of JAK inhibitor. We don’t have the same treatment for everyone. We’re looking at what we need to address in you as a patient.

If we’re trying to address high counts, a JAK inhibitor makes sense. If they have a big spleen and/or symptoms that will need to be addressed in combination with that, a JAK inhibitor would make sense based on the fact that we have the longest experience with it.

The Latest in Myelofibrosis Treatments - Clinical Trials

Ruxolitinib has been our first go-to. It was the first approved and we feel more comfortable with it. We know how to adjust the dose and move things around with it. If that doesn’t work, then the go-to next step in an ideal world would be a clinical trial.

If we don’t have one that would fit, it would either be fedratinib or pacritinib. The choice would depend on where the blood counts stand. If the platelets or the cell counts are on the lower side, pacritinib would probably be a better choice.

There are patients who have anemia as a major presenting symptom. In those situations, options such as epoetin alfa, danazol, pacritinib to some extent, and hopefully momelotinib in the future are some of the options. Luspatercept is in clinical trials; we’ll see how that pans out. Those will be some of the options.

The third set of patients is those who come with more advanced disease in the way of more excess or a higher fraction of blasts or leukemic cells or very, very early cells in the bone marrow that indicate that these patients are headed towards the pathway of a more aggressive pattern of disease like leukemia.

In those situations, either in combination with JAK inhibitors or without something like hypomethylating agents could be considered usually en route to a bone marrow transplant, if that makes sense in terms of eligibility.

Stephanie: What’s clear is this is very individualized. There are so many considerations.

The Latest in Myelofibrosis Treatments - Clinical Trials

What are clinical trials?

Stephanie: Mary, can you bring us back to the day when you got the diagnosis? What was that like for you learning about cancer?

Mary: When I was initially diagnosed, it was over a long period of time so it wasn’t shocking exactly as I grew into it.

I thought back to my own father, who had a rare blood cancer in the late 1980s, had it for five years, and died at age 60. In fact, we were both diagnosed at age 55. I felt like I was somewhat prepared for how to manage this because I’m in the health field.

I had a bird’s eye view of it with my own father and I knew how to advocate for myself, especially since my dad had to advocate at a time when there really weren’t a lot of options for this cancer.

There’s a lot of fear and a lot of wondering. Will I be around to see my grandchildren? Will I finish my career? Will I make the contribution to society that I had hoped? Will I have a painful death?

I’m grateful over the years to have learned that I have so many treatment options available to me that I don’t look at the future as something grim at all. I just see it as my normal life.

I’m so grateful to learn of combination therapies because not all of us can make it to stem cell transplant, which is ultimately our cure.

There’s a whole lot more hope on the horizon for us with MPNs, particularly primary myelofibrosis. I’m just grateful for the research and the amount of research that’s being churned out these days, the clinical trials, and the combination therapies.

I’m so excited to be able to talk to experts in the industry about research and development towards not only treatment but cure for myelofibrosis.

Stephanie: We’ve talked a little bit about some of the drugs and combinations that are being studied now.

The first time I heard the term clinical trials, it felt a little daunting. There are lots of misconceptions about clinical trials. We do know that different stakeholders are trying to research what can be better to improve the standard of care for different patients and patient groups. One of the challenges is that people view clinical trials as a last resort.

Ashley, we know clinical trials might not be right for everybody, but they are an access to tomorrow’s treatment today. We’re sure you get lots of questions in your role at the LLS. What are clinical trials in layman’s terms and what are some of the top questions and misconceptions you hear from people?

Ashley: Clinical trials are carefully controlled research studies, which are conducted by doctors, researchers, and scientists. They may be investigating new therapies or therapies used in the past in a slightly different way or in combination with other therapies to find out which works better or might have fewer side effects. They’re looking at both tolerability as well as effectiveness of the treatments.

There are so many misconceptions out there, but one of the largest is that it’s for patients who have exhausted all options. That’s simply not the case. There are clinical trial options at all stages of diagnosis.

There are interventional trials, which test treatment options, as well as observational or registry trials, which help us learn more about myelofibrosis as a diagnosis but may not involve specific treatments.

Another concern that we regularly hear about is the use of placebos. Placebos have definitely gotten a bad rap. A placebo can be known as a sugar pill. They’re not very commonly used in cancer clinical trials because it just wouldn’t be right for us to use a sugar pill in place of somebody who needed active therapy for a serious or life-threatening disease.

When placebos are used, it would be in a setting where a patient doesn’t require any type of treatment at that particular moment or in combination with another therapy so that the patient is continuing to receive active therapy for the disease that they have.

Logistical concerns may come up as well. We always like to chat with patients about travel for clinical trials and what that might entail. We’ve talked about some of the academic medical centers and how important it is to have an MPN specialist.

Very often, investigators who are looking at clinical trials for myelofibrosis are in academic centers. We’re always encouraging and pushing for those clinical trials to be available in the community setting because traveling to and from those academic centers can be a real challenge for patients.

In addition to the logistical travel considerations, there are some misconceptions that clinical trial participation is free or that patients may even receive money for participating. Unfortunately, that’s not always the case. It’s really important that we explain that to patients.

Parts of the clinical trial that are investigational or are not approved will be provided by the clinical trial. Physician visits and lab work are things that we would expect patients to undergo if they were receiving standard care. Those will still get billed back to the insurance company or may have to be paid for in another manner.

Each clinical trial is structured a little bit differently and it’s hard to know from an overview, but really it’s important to have a general understanding before diving into the specifics of any clinical trial.

If you are participating in a clinical trial, occasionally, there can be stipends available to support the patient or caregiver and that’s why it’s so important to reach out and find out more and make sure that you have all the information you need as you make a decision about participating.

Mary: Thank you, Ashley. It’s so important to hear that we do have access to medication, not necessarily the placebo. A lot of us do worry about that. We also need to check in to find out what is available to us in terms of financing.

The Latest in Myelofibrosis Treatments - Clinical Trials

Momelotinib, a new drug

Mary: Dr. Mascarenhas, let’s talk about single-drug therapy. There’s a new drug that was recently FDA-approved, momelotinib. What patient might it benefit?

Dr. Mascarenhas: Momelotinib is a JAK inhibitor so it’s much like ruxolitinib except as I mentioned before, there are some nuances that make these drugs a little bit different. It also inhibits ACVR1, which is another pathway that regulates iron availability for red blood cell production. In its long development history, it’s differentiated itself from other drugs in large part by its ability to improve hemoglobins in a subset of patients.

It went to the FDA based on a study called MOMENTUM. The expected approval was in late June. It was delayed by the FDA, which is not uncommon, to September for re-review. My expectation is it will probably be commercially available in the pharmacies and available for prescription likely by mid to late September.

I encourage patients to discuss with their physicians if that drug might make sense for them or any of the other drugs that we’ve talked about, whether it’s fedratinib, ruxolitinib, or pacritinib. As we’ve said, it really has to be tailored to the patient.

I’m excited to see momelotinib come up. For a physician, it’s great because it gives us different options and allows us to tailor the treatment for each patient. That might be a great opportunity for some patients to either embark on that therapy or switch.

The clinical trials set the tone for the interactions with the FDA about what that label would look like based on the way the clinical trial was designed and run. We can only guess that there may be stipulations.

It may only be available after the use of a first-line JAK inhibitor or it might have to have certain requirements for depth of anemia level. There are some nuances that sometimes play into the decision-making and these are based on the clinical trials that led to the approval.

Best drug combination therapies

Mary: Dr. Jain, there’s combination therapy to think about. June F. asks, “What are the best drug combinations at present?” Can you introduce us to combination therapies?

Dr. Jain: I’m not sure if I can answer what the best drug combination is right now, but hopefully that is a question we will learn more about and address in the future.

There are drug combinations that are promising. It brings options that we can offer to patients. They’re mostly in clinical trials but hopefully, some will move the field forward.

Historically, we addressed the JAK/STAT pathway, which we have learned the most about in the last couple of decades. That is the primary pathway involved in the occurrence of myelofibrosis.

As we have learned more over the years, there are other pathways that are critical to the development of myelofibrosis and that is where the rationale for drug combinations comes in.

We’ve seen several clinical trials that have addressed that or used combination therapy in patients who don’t have a good response to ruxolitinib itself and need more than that. Many of those drugs have been tested in the first-line setting to see if patients would do better with combinations upfront rather than ruxolitinib alone, which has been the long-standing go-to first-line treatment for over a decade now.

The Latest in Myelofibrosis Treatments - Clinical Trials

Some of the drugs that you’ll hear about are navtemadlin, for example, which is an MDM2 inhibitor. Dr. Mascarenhas presented data at EHA that showed a 35% spleen reduction in about one-third of patients in patients who weren’t responding to ruxolitinib itself.

There are BET inhibitors like pelabresib that I heard Dr. Mascarenhas talk about at ASH, which also is being tested in the first line in patients who are starting upfront treatment.

There are BCL-xL inhibitors like navitoclax, which have shown some improvement in the second-line setting. We’re awaiting a public announcement on the data for the first-line trial.

The premise is that you’re combining two mechanisms that have shown to work such that you do not have overlapping toxicities. That’s an important piece to remember. 

JAK inhibitors can cause some decrease in blood counts; we’ve seen that with ruxolitinib. You want to add a drug that may not do that as much or may not do that to an extent that makes it prohibitive of a combination.

With pacritinib, for example, patients often would get gastrointestinal toxicity so don’t combine a drug that may also have gastrointestinal toxicity. That’s important to remember as we think about combinations, which we will see more and more in the future.

Logistics are certainly important to consider as we’re thinking about clinical trials, what the trial offers, the frequency of visits to the center, and whether that makes sense in terms of continuing to be on it or not.

When to consider combination therapy

Mary: Dr. Mascarenhas, what should patients ask when considering a combination therapy like Dr. Jain just talked about? How do we know when it’s right or the right time to start one?

Dr. Mascarenhas: The first question to ask is: Why is this combination for me? What would be the advantage in my case in terms of addressing my goals of therapy? Importantly, what are the potential risks?

As physicians—and I’m definitely included when I say this—we often focus on what we think is going to be the advantage of participating in a clinical trial. The reality is there are disadvantages sometimes. There can be toxicity associated with approved drugs and unapproved drugs that are in clinical trials.

Patients want to understand expectations of results and the potential toxicities that one could incur. What does the patient need to be aware of in terms of mitigating and reporting?

A trial is not really a passive experience. Patients are active participants. They’re not simply receiving a drug. They have to be very willing and engaged to report all symptoms and not just what they think might be important. They need to report everything to the study team.

That might involve calling ahead of their visit to let the team know what’s going on, making sure that all their medications are accounted for, and they’re following up. It’s an opportunity to assess whether a drug is active and adequately characterize the toxicities of a drug. As the drug moves along, it’s optimized in the delivery for future patients.

There are two objectives. How is this drug going to help me and what is my role in this whole process? It really should be a joint venture. It’s not a one-sided experience. We learn from the patients. Hopefully, the patient community learns from what we’re doing and everyone benefits.

The Latest in Myelofibrosis Treatments - Clinical Trials

Stephanie: Dr. Jain had set up the landscape of combination therapies and talked about different options. Dr. Mascarenhas, it’d be great to run through a few specific combinations.

Dr. Mascarenhas: Clinical trials today to a large degree are unlike what clinical trials were historically. These drugs are all rational with supporting pre-clinical data. People don’t always realize that they go through enormous amounts of testing through various aspects before they ever enter a human being.

There’s an enormous amount of regulatory burden that exists that’s really annoying but really important because it provides that sense of confidence in the investigators but also in the patients that what we’re introducing makes sense. We’re not just taking something off the counter and saying, “I wonder if this is going to work,” and throwing it into a clinical trial. These are rationally developed drugs.

An example is selinexor. Selinexor is a really interesting drug. It’s already approved for blood cancers that are not myeloid cancer like multiple myeloma and other B-cell lymphomas. This drug affects the shuttling of proteins in different compartments in the blood cell, in the nucleus, and in the cytoplasm.

Why does that matter? Because if you can affect where proteins are in a cell, you can ultimately affect the functioning of these proteins. Selinexor inhibits this shuttling protein and affects the way certain proteins exert their function, which might be important to the pathophysiology of the disease. This might even turn on other proteins and put them in an area where they can actually induce a good effect.

For example, there is probably a multitude of different changes when you use a drug like selinexor that shifts the cell’s functioning from one in which it’s acting inappropriately and nefariously into one in which you try to induce it to die through normal mechanisms.

There are normal mechanisms that are built into our cells that if they get corrupted by a virus or by cancer, they turn on this mechanism called apoptosis and undergo programmed cell death. Cancer cells have ingeniously figured out ways to get around that. We struggle each day to figure out ways to get them back on track, to encourage them to recognize that they’re inappropriate and to undergo this programmed death.

Selinexor is a great example of a drug that affects multiple pathways and induces myelofibrosis, perhaps even the primordial cells, to undergo this process of death. It works best in combination with ruxolitinib and that’s a common theme that we’ve seen.

In oncology, it’s very rare, except for maybe CML or some other diseases, that we use monotherapies. In most of oncology, we use combination therapies to synergize together to get deeper responses and avoid overlapping toxicities.

That’s what we’re seeing with drugs like selinexor or navtemadlin, which has a great wealth of data at this point. These drugs are active as single agents, but they seem to be even more active in combination.

This is supported by studies that are done in mice that are engineered to have myelofibrosis with primary cells from people who have been generous enough to donate their blood cells. We experiment and figure out how we are going to make better drugs in the future.

I thank those patients. Seems like a small thing, but it’s a huge, huge aspect of how we move this whole machine forward in clinical research. All of that information allows us to say this combination really looks effective.

We’ve got JAK inhibitors that are commercially available. We’re going to add this drug that synergizes nicely in preclinical models and cells in the dish. We think it’s going to work better than each drug alone and we’ll figure out how to dose them and schedule them to minimize toxicity. That’s really where we’re seeing it.

The Latest in Myelofibrosis Treatments - Clinical Trials

Selinexor, navtemadlin, pelabresib (BET inhibitor), and navitoclax (BCL-xL inhibitor) all look good in combination with ruxolitinib. As Dr. Jain said, ruxolitinib has been around the longest and that’s the go-to drug that we combine drugs with.

We’re not even waiting anymore for patients to have failed the first line of therapy. We’re introducing the drugs earlier on. We get confidence in their ability and their toxicity profile. Why wait for patients to do worse? Why not try to get deeper responses earlier on?

The deeper we can reduce the disease burden, we believe that the better the patient will be overall. They will not simply feel better but have smaller spleens, which is important. Fewer disease cells in their body will hopefully mean longer progression-free survival.

Navtemadlin, selinexor, pelabresib, navitoclax, imetelstat — there’s a whole host of drugs that are aiming to really hit the clone and induce deeper responses.

Second-line treatment after Jakafi

Mary: For people who have been on ruxolitinib and, for whatever reason, the treatment wasn’t effective, what treatment options are available?

Dr. Jain: That’s a common situation we run into because as Dr. Mascarenhas pointed out, ruxolitinib has a very strong role. There are a lot of things that it does do, but there are a few things that it doesn’t do. Based on registration studies and clinical practice, if it works, it works for a few years and then we start losing that response.

A clinical trial available that would be a combination of a JAK inhibitor with something else or something added to ruxolitinib itself would be my go-to to consider. There are several of those going on at this time. There are also trials with single-agent drugs.

The way drug development goes is there’s testing of efficacy by using the drug alone. Then once we are comfortable with their efficacy and safety profile, we add it onto a ruxolitinib or a JAK inhibitor backbone.

If we see efficacy and safety in that combination, we move it up the ladder a little bit more and try to investigate if that would be a better option in the front line compared to ruxolitinib itself.

There are non-JAK inhibitor combinations that get added to ruxolitinib. Navtemadlin, an MDM2 inhibitor, has data. It restores the natural cell-killing pathway that should happen but is not working very well for some reason. We’ve seen patients respond in a post-ruxolitinib setting in terms of their spleen and symptoms.

There are other drugs like navitoclax, a BCL-xL inhibitor, that show responses in about one-third of the patients who were not having a good response to ruxolitinib by itself.

Pelabresib is a BET inhibitor. There are other BET inhibitors in the pipeline that are being developed with slightly different nuances to their conformation and how they inhibit the pathway. These are some of the categories of drugs that look promising and worth looking forward to.

Imetelstat has emerging data. It’s slightly different in the way it works. It inhibits the telomerase activity. It’s one of what we think happens in myelofibrosis or leads to that, even though the telomerase length may be not as long or in fact short. The telomerase activity tends to be high and that’s what imetelstat inhibits.

I’m sure I’m missing some here and that’s not for the lack of preference. Selinexor is another one that Dr. Mascarenhas already mentioned.

I would tell my patients that if we can get our hands on one of these combination clinical trials at that time, that would be my first go-to option.

If for any reason there are no clinical trial options available after ruxolitinib, then obviously there are other JAK inhibitors like fedratinib, pacritinib, and hopefully soon momelotinib. Patients may still benefit even though they stopped responding to or did not achieve benefit from ruxolitinib as a front-line JAK inhibitor.

When to get a second opinion

Mary: When is it right for a patient to seek a second opinion during this time of figuring out the right treatment options?

Dr. Mascarenhas: The right answer always is now. I don’t think it ever hurts to seek a second opinion at the time of diagnosis to confirm the diagnosis. There is a lot of heterogeneity in the way these diseases can present. There are overlaps and nuances.

It’s important to seek a second opinion because you may be a patient who should be considered for a bone marrow transplant, which is the only curative option we have. Sometimes that’s delayed too late and the patient misses the window of opportunity. For some patients, that may not be on their plate but having that discussion is really important.

I don’t recommend seeing lots of different people; that can be problematic. Getting a second opinion at each stage never hurts — at the time of diagnosis, if you’re not doing well on your first therapy, and when there’s consideration of second therapy.

If you have a physician who gives you pushback about getting a second opinion or comes across negatively, you might want to find another physician because it shouldn’t be an ego thing.

It’s your life. You’re dealing with cancer. You should feel free and confident that a second opinion is not a reflection of your treating physician. It’s getting more information and the more information you have, the better the outcome.

Dr. Jain: I agree with that 100%. The MPN community is small but also very well knit and I think we work very closely together. I’ve asked my patients to get second opinions and I’ve set them up for them if they need to go. I’ve sent patients to Dr. Mascarenhas and to others if there is, for example, a clinical trial opportunity that we may not have and they may have.

Sometimes it’s better for them to hear it from more than one person. We do a lot of things similarly, but there are some that we may have different perspectives about.

A common joke is if you ask 10 MPN experts, you’ll get 12 different opinions, and not because anything is right or wrong. There just may be a slight difference in our prior experience with a particular strategy or what our perspective about a particular strategy may be. All those are important things.

The role and timing of the transplant may benefit from a second opinion. Get another perspective as to what their center’s experience has been and how they may do something different. There are nuances to every transplant center and some of it may be more beneficial to you. Geography obviously plays a big role.

How to look for myelofibrosis clinical trials

Stephanie: We’ve talked about treatment options in myelofibrosis, but when you actually come down to needing to find one or stay on one, there are so many questions that we all encounter. We know that ClinicalTrials.gov is out there, but it’s a little bit difficult to navigate and that’s why the LLS’ Clinical Trial Support Center is so important. Ashley, what are your top recommendations in terms of looking for clinical trials?

Ashley: Often, people try to go about it on their own. ClinicalTrials.gov is the most comprehensive database of all clinical trials. In addition to cancer clinical trials, there are also clinical trials for all types of disorders and diagnoses.

It’s not always easy to hone in on what you need depending on past treatments you’ve had or medical history so it can be a challenging situation to find clinical trials that are actually applicable to you as an individual.

We always encourage reaching out to The Leukemia & Lymphoma Society. We have the Clinical Trial Support Center, which was developed as a response to help patients find clinical trials that are appropriate to them as unique individuals.

It’s a free service staffed by nurses who have expertise in blood cancers and clinical trials. Nurse navigators connect one-on-one with patients, caregivers, or even other healthcare providers who may need to learn more about potential clinical trial options.

We find out more about the patient’s diagnosis. We learn about any past treatments they may have had and find out about their medical history because all of those factors will play into a patient’s eligibility to participate in a clinical trial.

We also take a long time to find out about patient preferences and any unique obstacles that could hinder or drive participation in clinical trials. We help tailor some of the support and resources that we’re able to provide so that patients can overcome some of those barriers that may be in place.

The Latest in Myelofibrosis Treatments - Clinical Trials

After we’ve generated all of that information and really taken the time to get to know the patients, we produce an individualized clinical trial search. That could be related to geography and preferences. What matters most to the patient? Is this something that they’re really not interested in spending a long time in the hospital if they can avoid it?

We definitely look at all of those and produce a list that can be taken back and reviewed with their treatment team so that that can be part of the informed decision-making with the patient’s next steps.

We are available for all blood cancers, including myelofibrosis and other MPNs. It’s important to know that patients can reach out.

Half of the ongoing clinical trials are cancer clinical trials, but sadly, only about 5% of cancer patients actually enroll or participate. There’s so much opportunity out there and we’d really love to help overcome any barriers that patients might have so that they can consider participating.

The role of stem cell transplant

Stephanie: Transplant is such a huge topic for so many people and they hear so much about it. In the context of the landscape changing so quickly, do you feel that you and other specialists in the field will be recommending transplants less to people? This is probably a very individual response, but with everything happening, what’s the trend?

Dr. Jain: I actually think of it the other way. By virtue of having more effective treatment strategies to improve the spleen and symptoms, and get a disease response, we may be able to take more patients to transplant as a curative therapy.

A lot of times, lack of spleen response, poor performance by virtue of a lot of symptoms, or disease advancement into a more aggressive disease pattern become barriers to transplant. Having more options in the future will allow us to take more of these patients to transplant.

We’ve seen a lot of advances with a lot of these options. What we have not seen so far is the curative potential. Hopefully, we will in the future. All of these drugs have a lot of advantages in terms of improving spleen symptoms and cytopenias but we have not had definitive improvement or getting rid of the abnormal stem cell clone. That’s something that at least so far we’ve only achieved with a stem cell transplant.

At some point, as long as patients are eligible for transplant and that is something that would fit their life wishes in general, that would be a curative option to consider. Better non-transplant treatments will only get more patients to something more curative like a transplant.

Dr. Mascarenhas: I couldn’t have said it better myself.

Final takeaways

Stephanie: We’ve covered a lot of ground in a short amount of time. If there’s one thing you’d like for our audience of patients and care partners to walk away with, what would that be?

Dr. Mascarenhas: I hope to share my enthusiasm and optimism that we are making advances. There is a brighter future and I’m really genuinely excited about that.

Embrace the opportunity of clinical trials. Clinical trials are looked at for other people, but they may be important for you. Talk to your physicians. You may not go through with it but learning about it and exploring it is important for each patient.

Dr. Jain: It’s never a wrong time to see a specialist or to see someone else if something is not working out. Some symptoms are nonspecific. Never hesitate to be an advocate for yourself, to get things done, and to seek a second opinion.

As a transplanter, I’m obliged to pitch in that getting an opinion about transplant and at what course in your disease that makes sense is important to address. You don’t have to wait until you’re progressing or not responding to drugs. That needs to be addressed and outlined in an early appointment rather than waiting for too long.

Ashley: I really want to echo what’s already been said. It’s so important to consider clinical trials as part of the treatment plan. Even if they may not be an option at that particular moment, it’s important to be informed and look at all of those components as you’re making an informed decision about the treatment plan with your providers.

As a representative of The Leukemia & Lymphoma Society, I would really encourage any patient with myelofibrosis or any MPN to reach out. The Leukemia & Lymphoma Society has so many resources available, including clinical trial support but also so many others that we would really enjoy the opportunity to connect and provide those resources to patients.

Mary: Continue to have hope. Continue to want to thrive and live.

At the beginning of my journey with myelofibrosis six years ago, I was told I’d be dead by 72. Now they’re saying you could outlive this. You could die with this, not of it. Hearing both Dr. Jain and Dr. Mascarenhas talk about all these combination therapies and how they actually might get us to the cure was very exciting.

Conclusion

Stephanie: Thank you so much, Mary. Your story is so powerful. It’s also on our platform so feel free to check out Mary’s story.

Thank you to Ashley from The Leukemia & Lymphoma Society and to Dr. Jain and Dr. Mascarenhas for the work that you’re doing to push forward research and help patients and family members better understand their options in myelofibrosis and MPNs altogether.

I hope you’re able to take away something that was really key for you, because that’s our goal, to empower you in your own care. We look forward to seeing you at a future program.

How to Talk to My Doctor About Options

Edited by:
Katrina Villareal

The Hodgkin lymphoma treatment options live discussion took place in August 2023, hosted by The Leukemia & Lymphoma Society, Imerman Angels, and The Patient Story.

Sharing from real-life experience, the panelists were Stephanie Chuang, founder of The Patient Story and non-Hodgkin lymphoma survivor, Dr. Matthew Matasar, Hodgkin lymphoma specialist at Rutgers Cancer Institute, Dr. Samantha Siegel, both a doctor and Hodgkin lymphoma patient, and Chelsey Gomez, Hodgkin lymphoma patient advocate and artist behind Ohyouresotough.

The discussion covered an overview of Hodgkin lymphoma, standard, and emerging first-line treatments, options for relapsed/refractory patients including immunotherapy and stem cell transplants, managing side effects, the importance of doctor-patient relationships and shared decision-making, and key takeaways about community support and focusing on the quality of life during and after cancer treatment.



The Latest in Hodgkin Lymphoma Treatments - How to Talk to My Doctor About Options

Stephanie Chuang, The Patient Story: Hi, everyone! I’m very excited to have everyone to join us. We’re hosted by The Leukemia & Lymphoma Society, Imerman Angels, and The Patient Story. We have an incredible group of panelists tonight.

I’m a non-Hodgkin lymphoma survivor, founder of The Patient Story, and first and foremost, a patient advocate. The Patient Story was born out of my own experience with cancer. At the time, as a patient, I was looking for humanized answers for what my life with cancer would look like.

Fast forward to today, The Patient Story has hundreds of in-depth conversations and stories with cancer patients, care partners, and top medical experts in video and across our platforms. You can find us on ThePatientStory.com, YouTube, and social media channels. The goal for us is to help navigate people after getting that diagnosis.

We’re proud to partner with The Leukemia & Lymphoma Society or the LLS, which is the world’s largest nonprofit health organization dedicated to funding blood cancer research. They also provide a lot of education and services and that includes their information specialists who are just one call away to help with your questions. They also have financial scholarships and we’ll talk about that at the very end as well.

Last but not least is Imerman Angels, a wonderful peer-to-peer support group program. I used Imerman while I was a cancer patient and they will connect cancer patients and caregivers with mentor angels. They will use things like age, gender, where you live, and experiences to try and make that match.

We also want to give a special thanks to Seagen for supporting our educational program and allowing us to really do the work that we want to do in true patient education, connection, and space and provide it for free; that’s really important to us.

We want to stress that The Patient Story, The Leukemia & Lymphoma Society, and Imerman Angels all retain full editorial control of the entire program. A reminder that this is not meant to be medical advice or a substitute for medical advice. It is educational and we’re hoping that you’re able to take away great information tonight back to your own doctors and healthcare team.

Introduction

Stephanie: First up, Dr. Matthew Matasar, someone we’ve been able to work with before. He’s the chief of the Division of Blood Disorders at Rutgers Cancer Institute. He’s been a medical oncologist specializing in lymphoma for more than 25 years and leads clinical trials to try and find new and better ways to treat diseases like Hodgkin lymphoma.

Dr. Matasar, what drew you to lymphoma? What inspires you to do the research that you do and dedicate yourself to patient care?

Dr. Matthew Matasar: First of all, thanks for having me. I’m really thrilled to have this opportunity. What we’re doing together really matters and makes a big difference so thanks for making this happen.

I started out as a philosophy major back when I was in college, wanted to go into medical ethics, and then got sucked into oncology.

I saw oncology in general and lymphoma, especially as a place where I could make a difference, where being a really good doctor or being a crummy doctor makes a difference. I wanted to be the kind of doctor who listens to his patients, works with them as individuals, and understands that when they’re coming to me, they’re having the worst day of their life. I want to try to make it a little bit better using my brain and my heart as best I can.

If I do my job well, it’ll be better than if I don’t. These things matter and what I do matters. I feel this pride in knowing that what I’m doing is making a difference for people in my clinic, individual by individual, and by trying to develop newer, more effective, and less toxic treatments.

Maybe I could leave a little bit broader mark on the world. Trying to make a difference. What we’re doing here is trying to make a difference.

Stephanie: Yes, and you’ve been doing that and we really appreciate that you go above and beyond to help patients and their families.

Next up, from one doctor to another, Dr. Samantha Siegel, both a doctor and a patient, which is a really interesting perspective. Sam, I’m really, really grateful to have you here and lucky to get to know you. Thank you for all that you do.

We will get into your Hodgkin lymphoma story shortly but, first, we’d love to hear more about you outside of the cancer diagnosis because as we know, we are so much more than that.

Dr. Sam Siegel: Thanks for having me. I’m so excited to be here and to connect with you and all of the patients, caregivers, and community members.

I am one-half of a sandwich. I’m married to another doctor named Sam, but we got married before med school. Sam squared, Samwich, he Sam she Sam — a lot of iterations of that that are fun and interesting.

I’m a proud mom of three kids. They’re my best teachers in this world. They’re so incredible. Parenting them through cancer and through medicine has been very interesting. It’s always exciting. Our house is never boring.

I love jogging, painting, and playing guitar. I’ve recently become an enthusiast of ecstatic dance. It’s like a nightclub but during the day. No booze and kids are allowed. It’s just freestyle dancing.

I used to dance growing up and I’ve gotten back into it lately as a way to connect with myself and my body. I found it really helpful in healing from chemo and chemo treatment. I love dancing, music, moving through music, cooking, and food.

I’m hoping to unify how other people enjoy aspects of being alive and how we can talk to our doctors about how to tailor our cancer treatment to what matters most to us. That’s really important to me because if I couldn’t jog, play my guitar, paint, or work with my hands anymore, that would be pretty devastating to me.

All of that matters when it comes to talking with my doctor. I’m excited to be here as a doctor, as a patient, as a person, as a human being, first and foremost so thank you.

Stephanie: Thank you, Sam. I couldn’t have put it better myself. It’s not just about extending life, it’s the quality of life and even after treatment.

We will talk about the long-term side effects because we all want to live and get back to living the way that we know how and maybe better.

Up next, another awesome rock star. You may know her as the genius behind Ohyouresotough, which is amazing artwork. Chelsea Gomez, thank you for being here tonight. As a patient advocate, you’ve grown such a community yourself. Can you also tell us more about you outside of the diagnosis?

The Latest in Hodgkin Lymphoma Treatments - How to Talk to My Doctor About Options

Chelsey Gomez: Hi, everyone! I’m so happy to be here.

I’m from Florida. I just turned 33 and have a daughter.

I’m a professional artist. I own my own cancer awareness brand named Ohyouresotough. If you ever see anything of mine, you’ll see that I like to cope with hard things with humor. It’s really important to see the lighter side because a lot of the cancer world is not so fun.

I love all things art. I use clay, I paint, and I do digital art. When I’m not doing art, I’m running after my daughter to do whatever she wants to do, like play Barbies. I’m really excited to be here. Thank you for giving me the opportunity to share my story, too.

Stephanie: We appreciate it. Without voices like yours and Sam’s, we wouldn’t have the platform that we have today. Both of your stories are on The Patient Story so thank you for being here and for sharing your voice to help other people.

What is Hodgkin lymphoma?

Stephanie: Let’s get down to business. We’re going to try to avoid medical terminology as best as possible. Dr. Matasar, what is Hodgkin lymphoma?

Dr. Matasar: Working through things without terminology is theoretically what we’re supposed to be doing all day any day. When we’re talking to patients, families, and caregivers, we try to help people make sense of their illness.

What is lymphoma? Lymphomas are types of cancer. They’re cancers of cells called lymphocytes or immune cells. Lymphomas collectively are cancers that come from and are of the immune system.

That’s not to say somebody who has a lymphoma has a bad immune system — far from it. In fact, most people diagnosed with Hodgkin lymphoma have perfectly fine immune systems. They’re not constantly sick with infections.

For whatever reason, some cells mutate or change in a way that makes them live too long and start making copies of themselves. Then those copies live too long and they copy and the copies copy.

Compounding that, your body sees these cells that are copying that don’t belong there and views them as foreign or not right. In a similar way to an oyster that has a little grain of sand in it, it starts making a pearl around it. The body reacts to these cells and causes inflammation and scarring to try to wall off these weird cells causing even more swelling typically in lymph nodes, although that swelling can happen outside of lymph nodes in other parts of the body as well. It’s that swelling that usually leads to people being diagnosed with this type of specific cancer.

Sam’s Hodgkin lymphoma diagnosis

Stephanie: Sam and Chelsey, you had symptoms and red flags that helped you figure out something’s not right. Sam, what was your experience?

Sam: I wasn’t feeling right. In hindsight, it’s interesting to go back and piece things together, but I felt this vague sense of tiredness. I didn’t have enough gas in my tank. I was still running 10 miles on the weekends, but coughing a lot.

I didn’t have the steam for my usual level of physical exercise. I was coughing a lot, particularly at night. There were a lot of California wildfires at that time so I thought it was the air.

And, of course, I’m tired. Every parent during the pandemic is tired, especially with our kids doing homeschooling. It’s a whole different world. Then being a doctor at that time was very hard.

But then I got a rock-hard lump that appeared above my collarbone. It was painless and rapidly growing. As a doctor, I knew that I had cancer.

I got a scan and mine said something about possibly metastatic lung cancer or breast cancer. They weren’t sure so I needed to get a tissue biopsy. A little bit of time transpired between noticing the symptoms and getting the tissue biopsied.

Once that came back as Hodgkin’s lymphoma, I knew what the path ahead would be like. Around the time I was diagnosed in 2021, there was this big change that started happening with immunotherapy. It was the standard of what had been happening for a really long time, which is ABVD or a combination of four drugs.

I got on the eve of my 30th birthday. Then I started ABVD.

There was a question about my staging, whether I was stage 2AE or stage 4 because there was some lung infiltration. Long story short, that meant that I was going to get six months of ABVD. 

After a month or two, the coughing went away and I started feeling better. My cough came back at about month 2 to 3. We thought it was the bleomycin. I’m a runner and that’s very, very bad. We ended up dropping the bleomycin and I continued on AVD alone for the remaining four months.

Coincidentally, there had been a trial around that time to say that that’s okay, the de-intensification of therapy. Dropping the bleomycin became a standard thing, if people got a scan after a couple of months that showed that the body was responding.

My PET scan after two months looked really good. My cancer was responding and I was having that cough. We dropped the bleo and then I did four more months of AVD and boy, was it hard. It was really, really hard.

I had a lot of side effects. I struggled a lot and I struggled with that feeling. I hear people say about Hodgkin’s that this is the good one. It certainly didn’t feel that way. It felt really hard.

Stephanie: I hate when I hear whenever people say you got the good one.

Chelsey’s Hodgkin’s lymphoma diagnosis

Stephanie: Chelsey, how about you? What were the first symptoms for you or the red flags?

Chelsey: I was first diagnosed with Hodgkin’s in 2018 when I was 28. I was working a lot of hours so I was very tired, but I didn’t think much of it.

I had weight loss. I was trying, but it never worked before and then I suddenly started losing weight. I had shortness of breath and, at one point, I almost crashed my car because I had a vertigo episode. I ended up going to the doctor and they told me it was just stress.

The only reason I got diagnosed with Hodgkin’s was I eventually had a lump come up on the left side of the base of my neck. I went to urgent care. They told me that I just needed antibiotics, but there was something in their eyes that told me that wasn’t all I needed.

Eventually, my family forced me to go to the ER and we got a full biopsy done. I was in the hospital for the first time. Long story short, I had stage 2 Hodgkin’s and I also had ABVD. About halfway through, we had to drop below because I had toxicity.

I was re-diagnosed with Hodgkin’s in 2019 as well.

Dr. Matasar: First, hearing Chelsey, how you knew better, listened to your body, didn’t take no for an answer, and saw something that made more sense to you. The importance of that just can’t be overstated.

I meet so many patients who say, “Well, they told me not to worry,” or “My doctor told me to come back in six months and I was getting worse and worse, but I was told not to worry. I was told it was something else.” Congratulations on knowing better and I hope that people take heed and learn from the example that you set.

Chelsey: Especially when you’re young. It’s hard sometimes to speak up. But even if you’re young, you know your body.

Dr. Matasar: Maybe even especially if you’re young. We all know that old doctors sometimes don’t have the best reputation for listening to young people, trusting them, or taking them as seriously as they ought to be taken. Doubly so because of your youth at the time.

Changes in the treatment of Hodgkin lymphoma

Stephanie: Dr. Matasar, the treatment landscape in Hodgkin lymphoma has been changing quickly. Can you share about the evolution that’s been going on?

Dr. Matasar: Back in the ’80s, ’90s, and 2000s, clinical trials to try to make Hodgkin lymphoma better were all about intensification. How can I ratchet the treatment up to make it even stronger, even more toxic, but even stronger against lymphoma?

We were climbing that mountain of pushing to see just how much chemo we could cram into someone’s gullet in pursuit of a cure. All we had was chemo so what you want to do is more.

We’ve come over the other side of the mountain now and we’re in a very different place. As a discipline and lymphoma experts in the field, we’ve moved away from intensification.

We’re into de-intensification, personalization, and leveraging treatments other than chemotherapy as we try to help both maximize the chances of cure and minimize the short- and long-term risks of our treatment.

We’ve gone away from uniformly using ABVD, which remains a very good treatment and a very commonly used treatment.

More often, we’re now using other adjunctive treatments like brentuximab vedotin or ADCETRIS in lieu of bleomycin, which both Chelsey and Sam talked about potentially injuring their lungs, leading to cough or shortness of breath.

We’re finding ways to cure more people and, at the same time, cause less harm along the way and that’s really where the future of Hodgkin’s lymphoma is going to take us. We try to make even more progress on this mission towards more effective and less toxic treatments.

Stephanie: I love that that’s the trend and that we can continue going down that path. 

First-line treatment for Hodgkin lymphoma

Stephanie: We’ll talk about some of these newer promising treatments and new directions, but can you tell us a little bit more about the standard first-line treatment for Hodgkin lymphoma?

Dr. Matasar: As oncologists, when we meet a Hodgkin’s patient for the first time and we work through their treatment choices, we think through those choices together with our patients and their families.

We split people into different categories as we understand the risk of their disease and the options that are presented because of that.

One first way to try to put people into categories to help them think through their choices together is based on stage. We talk about early-stage Hodgkin lymphoma and advanced-stage Hodgkin lymphoma.

People will often ask, “What’s my numerical stage? Is it stage 1, stage 2, stage 3, stage 4?” We heard from Sam that sometimes, it’s not even clear to us as oncologists exactly what the stage is. Is it a stage 2E or is it a stage 4?

The staging exercise, which sometimes feels very black and white, can have shades of gray. We do our best to try to put people into risk categories informed by their stage and then think through the treatments that we know are best for that stage of illness.

Early-stage Hodgkin lymphoma treatment

Dr. Matasar: For the vast majority of people with early-stage Hodgkin lymphoma, the standard of care remains to be ABVD. It’s been around longer than I’ve been a doctor. It’s an oldie but a goodie and it still will cure the vast majority of patients.

Sometimes we think about radiation therapy as part of that treatment and sometimes not. However, ABVD for early-stage Hodgkin lymphoma remains the standard of care.

Advanced-stage Hodgkin lymphoma treatment

Dr. Matasar: For most patients with advanced-stage Hodgkin lymphoma, we’ve moved away from ABVD. This is based on really powerful clinical research comparing ABVD to a program where the bleomycin was swapped out in lieu of this newer immunotherapy called brentuximab vedotin, which is a type of drug called an antibody-drug conjugate.

An antibody is a protein that binds onto the surface of a cell and stapled to that is a toxin so this conglomerate attaches onto the Hodgkin cell, the Hodgkin cell absorbs it, and then the toxin is released inside the cell — like a Trojan horse sneaking into the city and releasing the soldiers inside.

This newer program where bleomycin was swapped out for brentuximab — so BV-AVD instead of ABVD — not only got more people into remission and kept them in remission longer, but actually led to a higher cure rate, people living longer, and everything good that we as doctors want for our patients.

Because of this important research, we really now use brentuximab plus AVD as our traditional standard of care treatment for patients with advanced-stage Hodgkin lymphoma in pursuit of a cure.

Role of radiation in Hodgkin lymphoma treatment

Stephanie: You mentioned radiation therapy as well and that has been its own sort of beast, if you will. There are a lot of considerations about long-term side effects and where the mass is located. What role do you think radiation therapy has been playing? What are your thoughts about whether it should still be used and in what situation?

Dr. Matasar: It’s a great question and you’re right, it is sort of its own beast. Back in the ’80s and early ’90s, almost everybody with early-stage Hodgkin lymphoma got radiation treatment as part of their care.

We knew then and now that using radiation therapy would cure a few more patients than not, but that slight improvement in cure rate never translated to people living longer.

It’s a trade-off. You may do a little bit better with Hodgkin lymphoma in some situations but you’re paying a steep price oftentimes in terms of long-term effects, late effects, and risks of health problems later in life.

That includes radiation therapy putting patients at a higher risk for other cancers later in their life, particularly younger women who need radiation therapy to the chest. If that radiation touches the chest wall and breast tissue, particularly for women under the age of 35 or especially under 30, it really does heighten the risk of breast cancer later in life.

Your heart also doesn’t like radiation therapy much more than the rest of you. We know that radiation therapy to the heart can lead to a higher risk of heart disease later in life.

There are all these consequences of the decisions that we make together in our pursuit of a cure. Because we know so well about these late effects of radiation therapy, increasingly, we try to be ultra choosy with whom we use radiation therapy.

We really restrict its use for what we think we really need to get a cure. For most patients, we can cure them just fine without using radiation therapy and putting people at risk for health problems later in life because of that treatment.

Use radiation therapy if you need to; it’s a great treatment. It can be life-saving when you need it but don’t use it willy-nilly.

Side effects of Hodgkin lymphoma treatment

Chelsey’s side effects of bleomycin

Stephanie: Chelsey, you experienced the toxicity and side effects of bleomycin. Can you talk to us about what that reaction was and what you did about it?

Chelsey: I had my fifth chemo right before New Year. I had chemo four other times, but I went home and spiked a really high fever all of a sudden. As a cancer patient, if it’s 100.4°F, you have to go. Mine was 102 and my husband said, “We’re getting in the car.” I was very lethargic and just not feeling well.

We ended up in the ER and they told me I was septic. Of course, my mom heard that as well. She was watching my daughter and she’s freaking out because it’s not good when you’re septic. They put me in the ICU and I was in the ICU for at least two days.

The symptoms dissipated after a few hours. I was feeling better, not 100%, but they started giving me antibiotics around the clock.

I had a feeling that it had something to do with bleomycin. I’ve researched what can happen with bleomycin because I have asthma and that was something I had to consider going into the treatments.

Everything I was seeing was adding up to it being toxicity, but there was nobody at that hospital who really treated cancer patients. They came in and out, but they weren’t there all the time.

It took about four days for my oncologist to actually come and see me. At that time, I pretty much diagnosed myself with bleomycin toxicity. I also stopped accepting the antibiotics because it wasn’t an infection. It was a reaction to this drug and it was confirmed later on.

I also had a pulmonary function test and I had a 30-point drop or something. I’m happy to report that I have regained a lot of my pulmonary function now many years out. For a lot of people, I know that’s something scary when you do go through this.

This was a local hospital and they had never seen this before. The doctor was saying, “You need to advocate for yourself, especially when you’re in a situation where you know your cancer probably better than the people that are there. It’s not your regular care team.” I had to speak up for myself and it was hard, but I did it.

Stephanie: I really appreciate that you spelled that out. Dr. Matasar talked about it earlier, too, and I know Sam’s a huge proponent of that as well.

You said it was hard and I think we’ve all experienced that as patients where you want to advocate for yourself. You hear it from other people. It can be a little bit difficult to speak up. Do you have any other tips for people who are on the fence about it, who aren’t sure if they’re supposed to speak up?

Chelsey: I wasn’t a great advocate for myself when I first got sick. The oncologist I ended up with was the one who was just walking by when I was in the ER initially and I thought it was fate. It wasn’t. Immediately upon meeting him in his office, he told me it was the good cancer.

I was like a unicorn of the Hodgkin’s. Nothing went how it was supposed to go. It wasn’t good at all. Sometimes I was quiet about it. I didn’t know what to do because I always look things up and he would call me Dr. Google but not in a nice way. I was scared to bring up a lot of things.

If you’re young and you’re scared or sometimes it’s when you’re female and you have a male doctor, it can be intimidating. Bring your family with you or somebody else you trust and have them speak up for you if you are scared to do it. I know a lot of people do that and it’s helpful.

When you’re inside that room, your mind goes fuzzy and you don’t even know what’s going on half the time. It can be the difference between having a good result or ending up pretty much needing a transplant like I did. I truly believe that if I had been a better advocate, I might have not needed one.

Stephanie: Thank you for going into all that. I can completely attest to blanking out in the doctor’s office and not hearing the same thing that my family heard. I appreciate that tip about bringing people in if you can.

Sam’s side effects

Stephanie: In terms of side effects, you worked with your doctor to manage them. Can you share anything that was helpful there? 

Sam: I had a lot of side effects. I had a lot of nausea and vomiting, yet I gained a ton of weight during AVD from all the steroids and I was developing a lot of problems from that. My glucose and liver enzymes were increasing. I had inflammation in various organs.

In hindsight, I think that was also making my neuropathy really bad because once my glucose got better and I lost weight, my pain and my nerves got better, too, despite the fact that I was getting more medicine that theoretically should have been impacting the nerves.

All your systems can be impacted. Taking care of the whole body is really important. I talked to my doctor about diet, lifestyle, and supportive therapy. What are some complementary therapies that I could try while getting my traditional medicines?

I also took a lot of medicine at the time. I needed pain medicine. I needed nausea medicine. I needed all the tools in the toolbox to cope with living day-to-day because it was just really hard.

The medicines caused a lot of mood and neuropsychiatric side effects. I had problems thinking. At some points, I had problems driving or following a list of simple items and that was really tough for me. That was a really far fall in terms of functioning, going from being a doctor to having trouble shopping a grocery list of five items so that was pretty devastating.

When I found out that I could do brentuximab as therapy leading up to the transplant, that gave me a huge quality of life back. As those other drugs cleared out and my body healed, I could think again and started feeling myself in here again. I’m not gone, I’m still there, and that mattered so much to me. It was a huge gift.

Stephanie: I really appreciate you bringing that to life because sometimes, we feel lost in that fog and how important it is to get any semblance of that quality of life back of ourselves. Your story shares that so powerfully.

Immunotherapy for Hodgkin lymphoma

Stephanie: We’re going to shift to combination therapy for the front line. Patient Matthew S. asks, “How successful have immunotherapy trials been in regard to Hodgkin lymphoma?” Dr. Matasar, can you explain the idea behind combination drug approaches and for whom would this benefit?

Dr. Matasar: We’ve talked about the progress that we’ve made with swapping brentuximab vedotin for bleomycin.

Matthew’s question about immunotherapy is a really valuable one. This idea of immunotherapy has really been a revolution in a lot of different forms of cancer, but nowhere has it been more impactful than in Hodgkin lymphoma.

When we talk about immunotherapy in Hodgkin lymphoma, what we’re generally speaking about is a class of medicines called checkpoint inhibitors.

One of the ways that these Hodgkin’s cells survive in our body is they are able to effectively shield themselves from our normal healthy immune system cells. They put up these barricades and ways of shielding themselves or hiding or preventing our immune system from doing the trash.

There are two checkpoint inhibitors that are approved for Hodgkin lymphoma, which are very similar medicines truthfully: one called nivolumab and one called pembrolizumab — we’ll call them nivo and pembro for short. These medicines are able to strip those shields off of the Hodgkin lymphoma cells and allow your immune system to see what it was otherwise blind to.

The treatment itself does nothing to the cancer cells. It does not kill a single cell all by itself. What it does is re-enable your own body’s immune system to do the work. It’s a game-changer.

When we use these medicines by themselves and use them as a treatment for a patient who’s been failed by many different prior chemotherapies, they’re able to put people into remission more than half the time.

They’re actually able to cure some patients. Despite chemotherapy having failed again and again and again, this medicine is able to eradicate the lymphoma. It goes away and never comes back. That’s amazingly powerful to be able to say and it’s an amazingly powerful treatment modality for patients with Hodgkin lymphoma.

The more we learn about how good these medicines work, the more we want to use them for more patients to try to help cure more people. It went from being a last-ditch effort after everything else has failed to be part of the treatment when it comes back. Using it in that situation was able to help more patients.

We’re now seeing the initial results of our first trials of using it as part of the first treatment. Instead of ABVD or brentuximab plus AVD, we’re combining nivo or pembro with chemotherapy like AVD and we’re starting to see very promising early results.

BV-AVD vs. ABVD as first-line treatment

Stephanie: How much is brentuximab and AVD being used? Is it standard of care or does it just vary depending on the hospital system or the healthcare provider versus going to ABVD first-line?

Dr. Matasar: It’s a little bit hard. Everybody’s situation is a little bit different. There are standards of care, which means that all things being equal, it’s sort of a one-size-fits-all approach.

Medicine is never that clean or that easy. There are times when ABVD would be a standard for early-stage disease, but we have to use brentuximab instead of bleo. There are people with advanced-stage disease who even if BV-AVD would be the standard, I still want to use ABVD for this individual patient.

This happens because doctors listen to our patients and we take into account their personal priorities, preferences, and individual risk profile. All of these medicines have their own pros and cons and their own risks and rewards.

A treatment program is best when it’s personalized and done in the context of a doctor and a patient having meaningful and valuable conversations about what matters to that person. Is it just a cure regardless of side effects? Is it being able to play the guitar and run? What is it about the treatment that we need to take into account as we map a path toward cure?

Stephanie: Any idea of when we could see the FDA approval of checkpoint inhibitors in the front line?

Dr. Matasar: Certainly not anytime soon. The first results that we had were read out at major conferences. This is still very early data.

When it comes to Hodgkin lymphoma, doctors were very conservative. We don’t want to mess this up. We know that the stakes are high and that many people will be cured with traditional treatments. We don’t want to change gears until we’re really confident that we’re not hurting people in the process.

The initial safety readout of this combination using the checkpoint inhibitors in the first treatment looked better than any of us expected. There are a lot fewer immune-related side effects than we’re accustomed to seeing when using these immunotherapies. They do have their own immune-related side effects.

We want to see the data mature, as we say. We want to see how people do over time and make sure that there are no dangerous signals about increased late effects or late side effects happening as we gain more experience with this treatment approach.

Long story short, we don’t want to change anytime immediately soon. We’re probably looking a couple of years down the road.

The Latest in Hodgkin Lymphoma Treatments - How to Talk to My Doctor About Options

Treatment for relapsed/refractory Hodgkin lymphoma

Stephanie: Dr. Matasar, how have the standard of care treatments for relapsed/refractory Hodgkin lymphoma patients been changing?

Dr. Matasar: Historically, when chemo failed, we would use other chemotherapy programs that use different chemotherapy medicines than the first cocktail. The most commonly used in America historically was a program called ICE: ifosfamide, carboplatin, etoposide. Different than ABVD because they’re different medicines, but still chemo.

We’ve moved away from ICE being the only standard of care and we’re using more of those other medicines — brentuximab, the checkpoint inhibitors. You can use one of them all by itself or in combination.

It’s informed, of course, by what we did the first time. If patients get brentuximab as part of their first treatment, we’re not going to rush into doing it a second time and want to do something a little different. Maybe we would use checkpoint inhibitors alone or combined with some milder chemotherapy programs.

This is the art of medicine. Trying to pick amongst a number of very effective choices and determining how to leverage those medicines and combine them to achieve our patient’s goals. Always with this view of maximizing the good and minimizing the bad.

Sam’s Hodgkin lymphoma relapse

Stephanie: Sam, you relapsed a month after finishing your first-line treatment. I can’t even imagine what a gut punch it was to go through all that and then find out that news. What was that conversation like about where you were going to go next?

Dr. Siegel: Gut punch is a really great way to put it because it was. I finished six months of ABVD, which then went down to AVD. Despite a scan saying that I had no evidence of disease, I felt pretty awful.

At that point, I wasn’t sure. Am I just feeling awful because this is just what a body feels like after you’ve had six months of this poison? Something in my gut was telling me that something wasn’t right yet, but my scan was clean so I just focused on recovery for a little bit.

Within a month, I started having symptoms that were eerily reminiscent of my initial symptoms — a wheeze only in the left upper part of my chest and a little pea-sized lump. That time around, I thought, Okay, I think I’m pretty clear what’s happening here.

I got a scan, which led to some biopsies and a diagnosis of a relapse. I’m already researching on Google the next treatment regimen that I’m going to have to go through. The whole while, I’m preparing myself that I’m going to have to go through ICE. 

I’m thinking for sure I’m going to have to go through something called ICE, DHAP, or one of these other regimens that have been used longer term for relapsed/refractory Hodgkin’s or salvage therapy.

When the relapse was confirmed, my doctor said, “There’s this drug now, a targeted therapy called brentuximab. Instead of doing ICE, would you be open to trying that alone for a couple of months and then repeating a PET scan to see where we’re at?”

There was a pretty decent chance that if the brentuximab didn’t get me into remission before the transplant, I would have to get ICE, a multi-drug, more traditional chemo. I was willing to take that chance because I felt so beaten up by having to get all those months of traditional cytotoxic chemotherapy and all the side effects.

The decision made sense to me at that time whereas maybe other people may have been, “No, I want to hit it hard and do that right away.” For me, I was going to take the least amount of poison possible to get me into remission before transplant.

It worked. I got a strong remission before my transplant. I went on to get the bone marrow transplant then I took brentuximab. I did almost a year of post-transplant consolidation treatment.

Because those studies and the data were just coming through, my doctor said, “You know, this is kind of becoming a thing now based on the research and this seems like it might really fit you based on how bad you’re feeling,” so that was perfect for me. I was so grateful.

Stephanie: The timing matters, right? It just happened.

Stem cell transplant

Dr. Matasar: The first thing to say is that there are two types of transplants. What we’re talking about so far is a treatment called autologous, or from yourself, stem cell transplant.

To call it a transplant is actually wrong. There’s no transplantation going on; it’s just a word that we use. This treatment that you’re hearing from Chelsey and Sam is basically just a trick. It’s a way of letting us give a round of super strong treatment.

With regular strength treatment like ABVD or ICE, we give those treatments and then let people recover. Sometimes if the chemo is stronger, you might need to boost the recovery.

Here, we’re talking about a single course of treatment, usually six days, that is so strong that if I gave it to my patient, gave them a hug, and said, “I’ll see you later,” I wouldn’t see you later. It’s too strong.

We need a very powerful antidote for such a powerful treatment. The antidote that we use is actually a person’s own stem cells, these special Adam and Eve progenitor cells that live in our bodies and let us heal.

We filter the blood ahead of time with a process like a mini dialysis where we filter out a few of those special stem cells. We put them in the freezer, give people six days of chemotherapy, thaw out those cells, and give them back as an antidote.

The course of the six days of treatment and the stem cell re-infusion as a little mini transfusion, that’s the antidote. That is we are calling a transplant.

That’s different than an allogeneic or donor stem cell transplant where there really is transplantation going on. Your immune system is being put to sleep and a new immune system from a sibling or a stranger is put into your body to give you a new immune system. We then task that new immune system with attacking your cancer. For us, that’s a very different ball of yarn.

Chelsey’s Hodgkin lymphoma relapse

Stephanie: Patient Caitlin M. asks, “For relapsed/refractory patients, are there other options aside from chemo to get into remission before a stem cell transplant?”

Chelsey, you went through immunotherapy, but unlike Caitlin, you didn’t respond. After three cycles, your PET scan showed disease progression. I can’t imagine what that was like.

It would be great to understand more about your experience in terms of the conversation you were having with your doctor ahead of the transplant. Are there questions you wish you’d ask your doctor?

Chelsey: I relapsed in the latter part of 2019. I switched to the Mayo Clinic for my care. I had been researching through the relapsed/refractory Hodgkin’s groups on Facebook. I saw nivolumab, brentuximab, and all of those things, and they were a lot less harsh.

I asked about it when I went there and it was a newer thing at that time. My oncologist said, “Yeah, we can give it a try. It’s had really good results.”

Sam mentioned that the side effects of ICE and the side effects of brentuximab are a night-and-day difference. I don’t think anybody wouldn’t want to try the less harsh one leading up to the transplant.

I had three of those treatments, had a scan, and my cancer progressed. My oncologist was honestly shocked as well that it didn’t respond whatsoever and that made me actually ineligible for maintenance, like what Sam had.

We switched to ICE. ICE was the first chemo where I had to be inpatient for three days every time. It was intense.

When your hair falls out on ABVD, for the most part, it’s slowly coming out. With ICE, it was clumps of hair coming out. I was very sick. It was very, very harsh chemo.

Chemotherapy & immunotherapy pre-transplant

Stephanie: Dr. Matasar, for relapsed/refractory patients, can you explain this combination of chemo and immunotherapy in the context of a transplant, hopefully, what this might lead to?

Dr. Matasar: Up until now, the goal for patients who have their disease come back despite good first treatment is to get their disease into remission and then into a round of high-dose therapy or autologous transplant in an attempt to maximize the chances of cure.

Can we cure people reliably and consistently without a transplant by leveraging these immunotherapies either alone or in combination with chemotherapy? This remains a clinical trial-type question; this is not a DIY thing.

My hope for the future is to use these treatments, particularly immunotherapies, to really limit our need to take people through the rigors of high-dose chemotherapy, cure more people, and cause fewer problems.

Determining the sequence of treatment

Stephanie: If the ABVD didn’t work, there’s a relapsed/refractory situation. Maybe there’s some radiation that’s been involved. You have studies about brentuximab, nivolumab, or pembrolizumab alone or in combination. How are doctors having that conversation about the right thing to do next? What is the most promising next course of option?

Dr. Matasar: This is the art standing next to the science. There is some artistry to what we try to do to figure out the right lid for each pot and how to help a patient navigate the course of their illness.

There is no one-size-fits-all anymore. It used to be ICE; that’s all we did. It worked well and it was awful. Now we have a range of choices.

You have to sit with a patient and think through it. How much disease is there that I’m trying to shrink away? How quickly is it growing? How do you feel? How sick is it making you? How quickly do we need to get you better? What was your first treatment? How well did it work? How badly did it not work?

Take all of these factors, try to cram it into your doctorly brain, and try to give some reasonable recommendations. Sometimes you’re going to be as gentle as brentuximab all by itself. Sometimes you’ll want to give more chemo. Sometimes you want to give checkpoint inhibitors alone or with BV. Sometimes you want to do checkpoint inhibitors plus chemo. These are all reasonable courses.

Ideally, what you’re doing as a doctor is working with your patient as a person, as an individual, and charting a course that makes sense for them, for their illness, and for their life.

Stephanie: It’s a really thoughtful response. Are some of the considerations the treatments you had before, how successful they were, what’s already been done… What about things like age or comorbidities or those kinds of factors?

Dr. Matasar: We try not to be ageist, but, truthfully, taking care of a 30-year-old is different than taking care of a 90-year-old and to not recognize that would be silly.

That being said, it’s always a matter of individualization — understanding an individual person’s goals, their preferences, what risks they’re willing to take, what matters to them, and then trying to figure out the best treatment for that person, given everything you know about them, about their value system, and about their goals of care.

Stephanie: Wonderful. I wish every doctor thought like you.

Long-term post-treatment side effects

Stephanie: We’ve talked a little bit about long-term or late-term side effects. Patient Ariadne J. asks, “What is known about long-term post-treatment side effects?”

Sam: I love this question because now I can plug survivorship, which is basically my newfound life passion as a patient-doctor. Cancer survivorship, even though a lot of people don’t necessarily identify with the word survivor, is an important thing to keep your finger on the pulse.

Survivorship applies to this area of medicine that’s changing and evolving. It’s anybody living after a cancer diagnosis and that could be during treatment if you’re on long-term treatment and that could be after your treatment is over.

There are a lot of ways that the cancer experience, even if the treatment goes perfectly, makes you question your life when you’re in your 30s and have your fertility changed. There are all these things that get impacted once you hear that big C word.

Survivorship is an evolving area in medicine that is trying to address all of that. For me, there was a lot. There was identity. There was this existential crisis. Death and dying and making sense of all of that.

The steroids and the other medicine that I had to take impacted my thinking and my emotions. I’m usually a pretty balanced, even person so that was a very hard roller coaster.

There’s some cardiac stuff for some people. Doxorubicin, which is part of the initial treatment, is something that we really need to be thinking about. We’re giving people this medicine that’s toxic to the heart in their 20s, 30s, and 40s. We need to talk about intensive lifestyle interventions like a healthy diet and cardiovascular exercise.

An overall program that focuses on wellness is hugely important in managing long-term side effects and integrative medicine. I’m doing an integrative medicine fellowship. I’m trying to unify everything that I learned in medical school with everything I needed as a patient to get better from cancer and cancer treatment and hoping to offer that to other people.

Those are practitioners that you could consider going to or looking up. Make sure that you communicate everything you’re trying and doing with all of the people who are in charge of your care, including yourself. You’re an important part of that conversation. Cancer survivorship is important for managing long-term side effects.

Stephanie: Chelsey, what were the long-term side effects for you? You talked about going into menopause, for instance.

Chelsey: The main thing I struggle with that is the most apparent in my everyday life is the cognitive side effects of all the different treatments. I honestly think it was from the extreme stress that I was under for so long.

I was on this job in an insurance company and I had to balance things with legal documents. I know that if I were to go back to that job, I would not be able to do it now and that’s taken me a long time to see that that’s okay. I’m still me and I just have to work with things differently.

I have fatigue a lot of times and joint pain. I often joke that inside, I’m 80 years old but on the outside, I’m in my 30s so it feels like that.

As Sam mentioned, there’s a lot of identity crisis that you have as a cancer patient. Who am I now? What happened to the old me? What can I do?

I really want to encourage people to seek community. Even just hearing from Sam, I’m sure some people will say, “Oh, other people feel like that?” That’s definitely what inspired me to start making art and connecting with others. It can truly make a difference in your long-term mental health in survivorship.

Stephanie: Thank you so much, Chelsey. You capture a lot of that in your artwork.

Stephanie: Dr. Matasar, with the newer therapies that are either just approved or in the pipeline, are we addressing some of these long-term/late-term side effects that hopefully people can avoid even years later after treatment ends?

Dr. Matasar: We are. A lot of the drive to develop these newer treatments has been informed by our understanding of late effects, cancer survivorship, and the risks that survivors of Hodgkin lymphoma treated with more traditional treatments go on to face.

We still need to follow with these newer treatments to watch for the possibility of late effects. We don’t believe that they’re going to cause as many or as severe, but part of the work of survivorship is learning from our survivors and walking that path with them as we see how their lives unfold over the years and decades to come.

The number one thing that I would encourage survivors to do is to work with your care teams on developing a survivorship care plan. It can be a paper document or a digital document. It should be something that lives with you that says what your diagnosis was, what your treatments were, and what our understanding is of what you can be doing to safeguard your health in the years to come.

That’s informed by understanding the possible long-term consequences of the treatments that you received, how doctors think you’re best served by taking care of yourself, and what doctors can do to prevent or reduce the risk of those problems as you go on to live your lives.

Stephanie: Wonderful. That’s a great tip. It’s great that the trend of more focus on survivorship after treatment is going to do wonders for so many people.

The Latest in Hodgkin Lymphoma Treatments - How to Talk to My Doctor About Options

Shared treatment decision-making

Stephanie: We all want to be more empowered in our care to be able to ask doctors the questions, to feel that we can, and to ask ones that will be impactful.

Dr. Matasar, you talked about how the right treatment for each patient depends on different things like age, health, transplant eligibility, and goals of therapy. How can a patient find out the best treatment options for them and in what order? From a doctor’s perspective, what should that conversation be to elicit the best response for patients and their family members?

Dr. Matasar: I was really disheartened, Chelsey, to hear your story of your doctor disparagingly calling you Dr. Google. Nobody should have to deal with this stuff anymore. We’ve got to be better than that.

Everybody should be empowered to come into a conversation with a doctor as an equal partner in this process. I tell my patients, “This is about you. It’s not about me. I’ve got no ego in this. This is your mountain that you’re climbing. I’m not climbing the mountain. I’m the Sherpa. I’m dragging your bags alongside you. But this is your climb and I’m here to help.”

As patients or as caregivers, if you aren’t feeling valued and heard, then you may not have found the right fit for you in terms of your care team. Everybody should always feel free to be getting a second opinion. I Not enough people take advantage of this sometimes. They don’t want to insult their doctor. I don’t want to be that guy or that gal and I don’t want to be a pain in the ass. Be a pain in the ass.

I like nothing more than when my patients are pains in the ass and they come in with lots of questions. It means they’re doing their homework and they’re really invested. They want to learn and take advantage of whatever I’ve got up in my brain. I love nothing more and any doctor should love nothing more than a patient who’s all in on partnering with me on making this thing work.

Be vocal. Do your research if you want to. You don’t have to. You shouldn’t have to. But if you want to and if it’s something that you value, then that should be celebrated by your care team and never put down.

Chelsey: Have open discussions with your oncologist. If you do find other studies or other treatments, they should be open to answering your questions about it and not being dismissive, even if it’s not an option for you. They should be able to explain to you why or why not.

If you’re a young person about to have a transplant, even if you’re not but if you’re in childbearing age, please ask about fertility. I’m now in menopause at 33 years old.

It was explained to me and I understood. We didn’t really have time to waste to get me to transplant. That’s a conversation you should bring up not only when you’re going into a transplant but also when you first get diagnosed with cancer.

Stephanie: Thank you, Chelsey, those are very important questions. I was lucky to have first-line treatment and be okay, but I asked that question before my intensive chemotherapy. It’s great whenever we’re reminded: advocate for yourself depending on what you want your life to look like.

The Latest in Hodgkin Lymphoma Treatments - How to Talk to My Doctor About Options

Finding a Hodgkin lymphoma specialist

Stephanie: Dr. Matasar, it’s clear that for relapsed/refractory patients, and if people are experiencing multiple relapses, it’s hard to find one answer from one doctor. They seek different opinions or get different responses. It’s a very personal discussion to be had.

Is there a right time to find a Hodgkin lymphoma specialist? When should that happen? How can you have that conversation?

Dr. Matasar: It’s tough because it’s very personal. My general philosophy is that people deserve to have expertise in their corner. I also recognize that people want to receive care close to home and they should be able to receive good care close to home.

In an ideal world, everybody would have an oncologist who lives close to them and everybody would have access to an expert to support the decision-making and to support the care journey. Sometimes that would be the same person.

If you lived near an expert, perfect. If you don’t have an expert in your neck of the woods and you want it, then you should have the opportunity to seek out that expert as a consultant and as a backup.

That doctor would work collaboratively with your local oncologist as a team to make sure that they’re doing everything to the best of their ability. You have the expert on standby in case things go sideways. In my mind, that’s the ideal.

If patients aren’t comfortable with what they’re hearing, even from me as an expert, go see somebody else. Hear from another set of lips. Get a fresh perspective. Maybe there will be a better fit in terms of that critical doctor-patient relationship.

Any doctor who doesn’t want you to get a second opinion doesn’t deserve to be your first opinion. Find the care that feels right to you. Trust your gut. The importance of the doctor-patient relationship is too great. It’s too critical in a relationship to settle for anything less than the best.

Stephanie: It’s so resonant and it’s powerful to hear from someone like you, Dr. Matasar. If the doctor doesn’t support you getting a second opinion, they’re not worthy of being your first opinion. I really love that.

Final takeaways

Stephanie: If there’s anything else you want to add, what would you really want people to take away from this discussion?

Dr. Matasar: I’m just bringing it back to The Patient Story. What you’re doing, what we’re doing together is where modern medicine should be. We should be building community. We should be sharing experiences and stories and supporting one another.

Every patient’s journey is unique and yet we don’t walk these paths alone. If you can find ways to build community and be supported by various communities, it makes the journey a little bit less painful.

Chelsey: He said it really well. When I went to my second doctor, I felt comfort and care that I hadn’t gotten before. Make sure that you are having a good relationship with your doctor.

A sense of community is very important because a lot of society puts a little bit of an expectation on our shoulders to always be brave, positive, and strong warriors, and not everyone feels that way.

I just want you to know that’s okay. It’s okay to authentically be yourself and talk about the hard parts of cancer, not just the smiling, ringing the bells, and all of that. There’s a lot more to cancer than that. It’s okay for you to feel the way that you feel, however that is.

Sam: Having lots of questions doesn’t make you anxious so it’s okay to have lots of questions and concerns and to look things up. It’s okay to reject that label because you’re just appropriately concerned about your life and the quality of your life.

Some doctors may be more attuned to knowing to ask about what’s really important to you in your life. Some people may be really busy that they forget that. As patients, it’s up to us to tell our doctors what’s really important to us and things that we like doing.

Share with your doctor what’s really important to you. Not only will it help them to know you as a human being, but it will help inform treatment decisions.

There were times during my treatment and I’ve heard from other patients where it felt like to want anything more than not dying was greedy. We’re beyond that now in medicine.

We are in the era of personalization, community, and individualized care within the guidelines of all the new things that are being discovered. It’s not greedy to want to keep exercising to some degree or keep doing your art or whatever defines the quality of life for you.

Tell your doctor what’s important to you. Reject the anxiety label. Let’s shift the focus from mortality to vitality in cancer. It’s so much more than just not dying. It’s the living part.

Stephanie: You both have exemplified that so much. I’m really grateful to have had you, Chelsey, and Dr. Matasar doing your work in research and helping patients and families holistically. Thank you for the work that all three of you are doing as advocates.
