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.

The Latest in DLBCL Treatments - Clinical Trials

Introduction

Stephanie Chuang, The Patient Story: Hi, everyone! This discussion is hosted by The Leukemia & Lymphoma Society and The Patient Story.

I was diagnosed with diffuse large B-cell lymphoma a few years ago and went through hundreds of hours of good, old-fashioned chemotherapy.

Thankfully, our discussion is all about other options that are happening, that have been approved, and that are in the pipeline.

We hear about clinical trials and the term itself can be so daunting. What are clinical trials? Our goal is for you to walk away from this with a much better understanding of what a clinical trial is and if it’s a good option for you or your loved one.

The Patient Story features hundreds of in-depth and authentic patient stories across cancers and conversations with top cancer specialists. The goal is to humanize cancer so that you know that you are not alone. Sign up to be part of our community and you’ll get first access to these programs, new updates, and stories.

We’re proud to be hosting this also with The Leukemia & Lymphoma Society, the world’s largest nonprofit health organization dedicated to funding blood cancer research and offering patient services and education. It has great resources from information specialists who help answer cancer questions to help pay for cancer care costs, including travel for CAR T-cell therapy.

I’m really excited to introduce our panelists. We’re really, really grateful to have them with us.

First off, someone I was lucky to meet at one of these big conferences. A very busy guy. I’m really excited that he’s spending the time with us. Dr. Joshua Brody, director of the Lymphoma Immunotherapy Program at the Icahn School of Medicine at Mount Sinai.

The Latest in DLBCL Treatments - Clinical Trials

Dr. Josh Brody: Thank you so much. This is a great opportunity. It’s really nice to try to reach out to talk to people as directly as we can.

I run the Lymphoma Immunotherapy Program here at the Icahn School of Medicine at Mount Sinai in New York. At Mount Sinai, we are very lucky to be an NCI-designated cancer center where one of our missions beyond patient care is trying to get the next generation of patient care, which is part of developing clinical trials and helping to get patients access to newer, hopefully, better and safer therapies.

I was committed to becoming a cancer doctor from the time I was six years old. As that developed, the plan was for me to become a cancer doctor who develops new immunotherapies for cancer.

We’re very lucky to have the best precedent of immunotherapies helping patients with lymphomas. Even what you called the standard old chemotherapy is not that old because rituximab is an immunotherapy that is part of that old chemotherapy and when I started doing this, rituximab was not even a therapy.

Immunotherapy has a great precedent. Using the patient’s own immune system to help fight their cancer has a great precedent in lymphoma and that is part of what got me interested in lymphoma.

I was doing my training at Stanford in California and it’s a very well-known lymphoma place so it was a great opportunity to hopefully become great at what they are great at. There were a few things converging to get me to become a lymphoma doctor and now I’ve been doing it for a while.

Stephanie: Really grateful that we have people like you who’ve been in this for so long and are so dedicated to helping to figure out what is effective and also what will help with quality of life.

Next, we have Crissy Kus, a nurse navigator with The Leukemia & Lymphoma Society’s Clinical Trial Support Center. We know that you are on the phone all the time helping patients and their family members.

The Latest in DLBCL Treatments - Clinical Trials

Crissy Kus: Thanks, Stephanie. I became a nurse about 12 years ago and started my career early, moving around the units in the hospital every 4 to 6 weeks. After a year of doing that, I was allowed to choose a home unit. I knew pretty quickly that BMT was my home, working with patients with blood cancers.

I help patients specifically with CAR T-cell therapy and lymphoma. I’ve been with The Leukemia & Lymphoma Society in the Clinical Trial Support Center. We’re a team of nurses who help patients and their families explore clinical trial options, learn about their treatment options, and navigate that whole journey — whether that’s proceeding with the standard of care and learning about those details and logistics or identifying barriers to participating in clinical trials and helping them overcome any of the barriers in the way of them participating.

Stephanie: Thank you, Crissy.

I’m also really excited to introduce our final panelist tonight, Dr. Robyn Stacy-Humphries, who has such an incredible story. Someone I’ve gotten to know and I feel very lucky to know you.

You have such an incredible perspective as someone who is a physician who got your own diagnosis not just once but going through treatment three times.

The Latest in DLBCL Treatments - Clinical Trials

Dr. Robyn Stacy-Humphries: First of all, hats off to Dr. Brody. We’re very lucky to have him on this panel.

Like Dr. Brody, I actually wanted to be a doctor from the time I was five or six years old. I went to medical school and residency in radiology and my subspecialty is cancer-focused. I do body imaging, PET-CT, and mammography. I diagnose cancers and do biopsies.

Ironically, I was diagnosed with lymphoma in my late 40s. Very much of a shock to be on both sides of it. Both my parents passed away from cancer of different kinds and then I developed one myself.

Navigating the cancer world as both patient and physician has been unusual and that’s one of the reasons I’m thankful to be here. One of my missions is to try to give back, to try to bridge the gap between doctors and patients so that they can learn to talk to each other better. Patients can learn to advocate for themselves and doctors can perhaps understand where they’re coming from.

Stephanie: Thank you for being here and for offering a perspective that is very unique. We have two physicians on tonight who really care about the patient’s perspective.

This is a personal topic for me as well. DLBCL is all over my medical charts. I was 31 when I was diagnosed and like you, Robyn, there’s that shock. I remember trying to understand: what do these letters mean? Lots of alphabet soup coming at you when you get diagnosed with cancer of any kind.

The Latest in DLBCL Treatments - Clinical Trials

What is DLBCL?

Stephanie: Dr. Brody, in as human terms as possible, what is diffuse large B-cell lymphoma? Are there some common first red flags or symptoms?

Dr. Brody: For Stephanie, I have to apologize for the alphabet soup. That’s a thing we do. We make up code names with lots of letters but not just to be confusing. There’s so much we’ve learned in decades that we make subsets of subsets and then we need more alphabet soup to describe all the subsets. PMBCL, DLBCL, non-GC — it’s letters on top of letters.

Anything that we can say in medicine or science, we should be able to say it in English as well. None of it’s so complicated that we shouldn’t be able to say it in English, especially when we’re talking to our patients. We have to be able to say things in a way that is understandable.

In regular English, lymphoma is a cancer of lymph cells. What are lymph cells? This is really simple. You think about breast cancer, cancer of breast cells, prostate cancer, cancer of prostate cells. It’s a healthy cell that becomes a cancer.

What are lymphocytes? Lymphocytes are a certain type of blood cell. They are specifically blood cells that may live in your lymph nodes. When you say swollen glands because you had a cold or a sore throat or something, those glands we’re talking about are usually lymph nodes.

Lymph nodes are all around your body. That’s the first tricky thing because when you think breast cancer, prostate cancer, you think, “Oh, I know where the breast is, where the prostate is,” so that makes sense. Lymphoma comes from lymphocytes, which mostly live in lymph nodes, so that could be anywhere in the body.

The Latest in DLBCL Treatments - Clinical Trials

Common symptoms of lymphoma

Dr. Brody: The common presenting symptoms of lymphoma depend on which lymph node area had a cell become cancerous. Amongst all of those possibilities, we still say that the most common presentation is a painless, swollen lymph node literally anywhere in the body.

There are subsets of lymphomas that don’t even show up in a lymph node per se. Sometimes we talk about primary mediastinal B-cell lymphoma. There are lymph nodes there, but they’re not in the common lymph node spots. We think of the neck, the underarms, and so forth. They just show up in the middle of the chest, the mediastinum. Nonetheless, the most common presenting symptom is a painless lymph node.

Lumps you get because you had a sore throat are not a painless lymph node. Usually, they are painful or tender lymph nodes. If you have a tender lymph node, that’s a little less likely to be lymphoma than inflammation as a result of a cold or sore throat.

Again, not every lymph node that gets a little bit swollen needs to be emergently evaluated. Otherwise, every person would have a swollen lymph node at some time or another.

The first thing we have to pour on this is a bit of common sense. You have a lymph node that’s a bit swollen for a few days. You can watch it for a few more days and if things start to recover on their own, probably you don’t need to go and get that swollen lymph node evaluated.

Lymph nodes that are swelling, usually painless, and getting worse over weeks and weeks and weeks need to be evaluated. Those are the most common presenting symptoms of diffuse large B-cell lymphoma, which is the highest incidence type of lymphoma.

Stephanie: I really appreciate you sharing the differences between what is more commonplace versus when you need to maybe get something checked out. People do get really worried.

Robyn’s DLBCL diagnosis

Stephanie: Robyn, you went through this yourself so it’d be great to hear from you. What was it for you that was a red flag that led to the diagnosis? Share a little bit about getting that diagnosis.

Robyn: I had a swollen lymph node, but it was an unusual location in what’s called your supraclavicular region. You never have normal lymph nodes there. When you have a cold, those don’t swell up. Usually, when you have a lymph node above your collarbone, it can be a symptom of lung cancer, gastric cancer, ovarian cancer, or even breast cancer.

I felt a lymph node literally while I was watching TV. I knew it was bad. It’s never good.

My process for diagnosis went very fast. I ended up with a CT the next day, which I looked at and found out I had lymphoma. I had lymph nodes all the way up and down my neck, which you couldn’t feel. They were all very small. There were too many of them.

I actually had some lymph nodes behind my nose and something called Waldeyer’s ring. I thought I had allergies. I was congested and that actually was lymphoma.

I really had no symptoms besides that. I was working 60 hours a week as a mother of three. I ran every day. I ate well.

Everything went really fast. It was a shock. Before I knew it, I had a CT scan, a PET scan, and a port put in, and immediately started on R-CHOP, which is the standard therapy. It was initially very successful for me. It didn’t work later, but it was very successful at first.

I did six rounds of R-CHOP and as Dr. Brody said, rituximab changed everything. When I was in medical school, non-Hodgkin’s lymphoma cure rate was very low, only about 30 or 40%. Once you added rituximab, it’s over 70% in a lot of cases.

Things have progressed in the last 10 years. Now with the immunotherapies, things are totally different.

The Latest in DLBCL Treatments - Clinical Trials

Stephanie: What a strange experience to have essentially self-diagnosed and have to read your own scans and images, but you do that for a living. I appreciate both of you talking about just how quickly things have changed in the last 10 to 15 years and even in the last five years or so with immunotherapy.

That’s what’s exciting to talk about but also why these programs are so necessary because it is a lot. It’s great to have people who specialize in this area so that there’s a depth of knowledge about all the different options and for whom these options are best.

Standard of care for DLBCL

Stephanie: Let’s talk about the standard of care. Dr. Brody, what has been the standard first-line treatment in DLBCL? We heard Robyn talk about R-CHOP.

Dr. Brody: For the past 20 years, there’s been a bit of an evolution. R-CHOP has been the standard of care. It doesn’t mean that everyone gets R-CHOP, but most people do — certainly more than 80%, probably more than 90%.

Some people may not get R-CHOP maybe because it can be a little tough. We have patients who are in their 90s and they may get a gentler version of R-CHOP or even slight variations of that. We do have patients in their 90s who still get R-CHOP, but it’s not gentle therapy.

The Latest in DLBCL Treatments - Clinical Trials

We sometimes give gentler versions and sometimes even more aggressive versions. There’s a therapy called R-EPOCH. It’s a tougher version of R-CHOP.

In some ways, it seems to be “better” in that it’s maybe more effective, but in a big randomized trial comparing the two, there wasn’t a clear difference. We think that R-EPOCH is just good for certain super high-risk subsets of patients so 5 or 10% of patients get R-EPOCH instead of R-CHOP.

The Latest in DLBCL Treatments - Clinical Trials

That was a big evolution from the CHOP of the 90s and easily added a 10-plus percentage increase in the cure rate to standard therapy for patients with DLBCL so it’s a big, big deal.

I was very lucky because rituximab came out of Stanford and Biogen Idec-Genentech back in the early 2000s so it was an exciting time for us. We now enter the rituximab era of treating patients with DLBCL. Now we’re still seeing comparably exciting evolutions to what may be the standard going forward.

The Latest in DLBCL Treatments - Clinical Trials

Stephanie: Amazing to have all that history and to be front and center when it was all going on; that must have been exciting.

We have a recent approval, polatuzumab and R-CHP, which is R-CHOP without the O for first-line treatment. How much real-world data is there? What are your thoughts about it as another option for people?

Dr. Brody: Pola-R-CHP, we say, is another option. It’s not the right answer, but it might be the right answer in the future. We’ll see.

There’s a randomized trial, POLARIX, where half of the patients got R-CHOP and half got pola-R-CHP. Pola-R-CHP was a bit more effective where 6% more people stayed in remission for the first couple of years. It’s possible that could eventually translate to an increased cure rate, but we need more time to follow those folks and see how they do.

The Latest in DLBCL Treatments - Clinical Trials

But a 6% increase, staying in remission for two years, that’s not nothing. If you were one of those six out of 100 people, that’d be a big deal for you. The only catch is it’s not “for free” in that there are some extra side effects but not too bad. The risk of infections during the therapy was moderate, but it was also a bit increased in the pola-R-CHP. Interestingly, it was about a 6% increase on that side as well.

Maybe 6% percent more people staying in remission and maybe 6% more people getting this significant side effect. The side effect lands you in the hospital so it’s not nothing. A little bit tougher on lymphoma, but a little tougher on patients as well.

The Latest in DLBCL Treatments - Clinical Trials

I wouldn’t say it’s the right therapy for everybody, but certainly, every lymphoma doctor is weighing each patient. It’s supposed to be personalized for each patient. This patient might do well because they’re younger, healthier, and wouldn’t have a high risk of side effects and this other patient may not do well.

A 90-year-old probably wouldn’t get pola-R-CHP because R-CHOP is already tough therapy for them. Higher-risk patients and certain subsets of high-risk patients might get the most benefit from the pola-R-CHP. Probably in the near future, maybe half of the patients are going to get pola-R-CHP and half are going to get R-CHOP.

Risk of relapse with DLBCL

Stephanie: That’s great. Thank you for sharing that and interesting to hear. We’d like to take in one of the patient questions actually. Wilson asks, “What’s the risk of relapse with DLBCL and what is the leading treatment for those who relapse?”

Dr. Brody: As Dr. Stacy-Humphries said, we cure the majority of patients. This is awesome not just compared to the 90s, but compared to the 70s when I had relatives that had this disease. We cure the majority of patients and that’s wonderful. It’s not 100% and we would like to get it there.

Today, we are curing more than 65% of patients, depending on which study you look at. A third of patients could still relapse.

These studies focus on slightly younger, slightly healthier patients. If you look at everybody, it’s probably about 65, maybe a little bit above that with “standard” 2023 therapies. We see that increasing as well over the next few years.

The Latest in DLBCL Treatments - Clinical Trials

Relapsed/refractory DLBCL treatment

Dr. Brody: The standard of care for them depends on a few things. It depends on when they relapse. If patients relapse very quickly, within the first year, the approach is a bit different. The idea is they just got chemo and it didn’t work very well so giving something that kills cancer in a different way might be better.

In the TRANSFORM trial and the ZUMA-7 trial, early relapsers and people that didn’t get a good remission at all or refractory patients, CAR T cells were superior to the old standard.

The old standard was basically more chemo and actually a lot of chemo, which was tough therapy. Those trials both showed that CAR T was better. If you read between the lines, they were also, I would say, safer and better tolerated. That’s a rare win-win, both better and safer. We don’t get a lot of those in new cancer therapies.

With pola-R-CHP, it wasn’t really a win-win. It was maybe better, but not safer. CAR T versus the old standard of more chemo was a real win-win. For early relapses and refractory patients, CAR T is the standard of care. It doesn’t mean every patient has to get it; there’s still some individualization. But for the early relapsers, that’s been the big change over the past year and two. That was not the standard of care even a couple of years ago.

The Latest in DLBCL Treatments - Clinical Trials

For patients whose disease relapses later, it’s even more individualized. The old standard for younger patients with late relapses was this mega dose chemo approach called autologous stem cell transplant. Autologous means you give the stem cells to yourself. We want to distinguish it from the other kind of transplant where you get stem cells from another person called an allogeneic stem cell transplant.

The Latest in DLBCL Treatments - Clinical Trials

For people who relapse a little later and who are young and tough enough to tolerate this tough therapy, that is still the standard but that doesn’t really apply to every patient. When we did those first studies, they were for people under 60 then we started doing it for patients under 65. Now we do it for patients under 70.

It’s tough therapy for people who are around the median age of this disease, which is upper 60s and 70s. It’s standard of care, but a lot of times for those late relapsing patients, they may not be eligible for that approach. Thankfully, there’s a whole bunch of other more targeted options.

Robyn’s 1st DLBCL relapse

Stephanie: Robyn, you had a good response to R-CHOP in the beginning. As you mentioned, it didn’t stay that way. We’d love to understand more about what happened. How far along were you until you realized something was not right again?

Robyn: I was actually in complete remission for four years when my relapse happened in 2015. Again, I felt a lymph node in my neck, which I knew wasn’t supposed to be there.

The Latest in DLBCL Treatments - Clinical Trials

As Dr. Brody said, the standard of care at that point was an autologous stem cell transplant. First, they give you salvage chemotherapy; RICE is what I received. It’s very rough chemotherapy. I also got intrathecal chemotherapy to prevent the lymphoma from going to my brain.

When I was confirmed to be in remission, they went ahead and did the stem cell transplant. They harvest stem cells and oblate your bone marrow using the strongest chemo possible then give you your marrow back.

It’s really a rescue. You have no stem cells left. They give you your marrow then you have to wait for your marrow to come back.

The biggest risk is infection. I got called septic shock and was very, very sick in the intensive care unit on medicines and pressors.

When I survived that, because my case was slightly unusual, it was decided among several institutions that I get radiation, which was really horrible. Two thumbs down, don’t recommend it, but I’m still here.

I was very, very sick. I couldn’t eat solid food. I dropped from a BMI of 22 down to about 15 or 14. It was quite difficult. I was actually trying to work. It wasn’t great, but you do what you have to do to survive. I did get great care so my doctors were fantastic. It’s just I had some complications.

Robyn’s 2nd DLBCL relapse

Robyn: I was in remission for nine months after the autologous stem cell transplant when the lymphoma came back. This time, it came back even more aggressively. Not only was it in my neck, it was underneath my armpit and in my groin.

I had no match for an allogeneic transplant — no one was even close. The doctors were very shocked. But I had already decided I did not want to go through that again.

The Latest in DLBCL Treatments - Clinical Trials

I researched on ClinicalTrials.gov on my own. We started looking at other options. I heard about T-cell therapies. They talked about killer T cells and CAR T. It had been in the news in 2015 or ’16.

I started looking into that and that’s how I ended up going into a clinical trial. I’m very, very grateful I did. It was a phase 2 trial. It was definitely a leap of faith, but I just had a feeling it was the right thing for me.

I was an excellent candidate because I was in really, really good health except for the lymphoma. For a clinical trial, this is perfect because I had no comorbidities. That way the doctors could actually figure out if this was going to really work without something else that would interfere with the procedure.

Stephanie: ClinicalTrials.gov is a great resource. It is not the easiest to navigate, especially for a layperson so that is where the LLS’ Clinical Trial Support Center is so wonderful. Resources like that help people really navigate what’s out there.

The Latest in DLBCL Treatments - Clinical Trials

What is a clinical trial?

Stephanie: When we talk about clinical trials, the research is happening to hopefully help provide more options for people.

A lot of patients have talked to me about efficacy or how successful it is at saving your life or increasing your life span and safety, which is quality of life and side effects. I want to live longer, but how is my quality of life going to look?

Dr. Brody, you’ve been involved with so many clinical trials. What is a clinical trial?

Dr. Brody: We should take Dr. Stacy-Humphries’ example of this. Robyn got that in 2016. There were no FDA-approved CAR T cells in 2016. They got approved in 2017.

Clinical trials are lifesavers. They are an opportunity to get access to a thing that is not yet FDA approved or sometimes things are FDA approved but a newer version or a better version or a combination.

In Robyn’s case, that was the only way to get access to CAR T cells, which years later, we realize are in many ways superior to autologous transplant and RICE. Not in every setting but in some settings, blatantly superior.

Clinical trials are carefully regulated opportunities to get access to medicines or combinations of medicines that are just not yet FDA-approved. This is a preview of future medicine. We don’t want to oversell it because not every clinical trial is successful.

We can’t ever do a trial unless we get all of these things blessed by many different groups, institutional ethical boards, local ethical boards, and the FDA. It is a way of getting access to things that are not yet FDA approved or not yet FDA approved in that combination or in that specific way.

Lymphoma is the fifth most common cancer in America. Pretty common but not as common as other ones like breast cancer. We have more medicines for lymphoma because we’ve been lucky to have more successful clinical trials and more rapid progress.

Researching clinical trials

Dr. Brody: The great thing about clinical trials is the tough thing about them: finding which one is where and at what time. ClinicalTrials.gov is the same tool we use, but it’s not super user-friendly. You can look at it and you might get the answer. At the very least, it might guide you to who to call.

There is no one best way to find out what is the right clinical trial for me. Even if you ask your doctor, they know about some, but it’s hard to know about every single trial in America at any given moment because they change even from month to month.

Stephanie: Crissy, how can someone look up what clinical trials are out there on their own if that’s the direction they’d like to go in?

Crissy: ClinicalTrials.gov houses every cancer clinical trial and general treatment clinical trials in the United States and some outside of the United States as well. Patients can go on there and look up information about studies pertinent to their case if they’re interested.

The Latest in DLBCL Treatments - Clinical Trials

I will give a fair warning. In my previous job, on at least a weekly basis, I had to help hematologists in the navigation of that database. These were really bright physicians and physicians who were the primary investigator on many of these trials and they had a hard time navigating the database.

I tell patients to say don’t get down on yourself. If you looked at that database and it was overwhelming, that’s where we come in. We have a database that sits on top of ClinicalTrials.gov and has all the information that it has. It allows our nurses to update and augment that information in real time so that it’s as updated as possible and has additional logistical information so that we can best communicate the information to patients.

Additionally, most large cancer centers or NCI-designated centers have a page on their website that has all the clinical trials that they have at their site. If a patient is specifically interested in a certain institution in the US, they can likely go to their page and look at the clinical trials that they have.

It’s generally going to link them to ClinicalTrials.gov where they can look at more information about the trial, but most institutions have really good databases on their own that talk about the clinical trials that they have at their site.

Misconceptions about clinical trials

Stephanie: Crissy, you’re on the phone a lot with patients and their family members answering questions about clinical trials. What are the top questions that you’re getting and some of the misconceptions that you’re hearing about clinical trials?

Misconception #1: Getting a placebo

Crissy: One of the biggest misconceptions that I hear from patients almost daily is that they’re worried about participating in a clinical trial because what if they get the placebo part of the trial?

In the United States, placebos are very rarely used in clinical trials. When they are used, they’re not used alone. A patient with cancer would never get just a placebo and not some type of effective treatment. The way that a placebo would be used in a clinical trial would be in addition to something that is proven to already be effective.

A really simple example that I give patients using CAR T as an example is if they wanted to study a drug in addition to CAR T that will make CAR T more effective or have less toxicity.

The way that a placebo would be used in that setting would be if you had 100 patients all getting CAR T as the standard of care and 50 of the patients get CAR T and then they get a placebo and then the other 50 patients get CAR T and a drug that’s being studied to see if it makes CAR T more effective or less toxic.

Every patient in the clinical trial is still getting the minimum standard of care. Some patients are getting something to see if it makes it more effective or potentially less toxic and the other patients are getting a placebo.

Misconception #2: Clinical trial is free

Crissy: Another big misconception about clinical trials is that everything on a clinical trial is free or that if a patient doesn’t have insurance, they can participate in a clinical trial to get a drug for free. Unfortunately, while I wish that that was true, it’s not.

There are three buckets of costs that we describe to patients.

Bucket number one is things that are free, things that the patient is not responsible for, and their insurance is not billed for and those are things that are investigational. The study drug that’s being used in a clinical trial? Not billed to insurance. Any follow-up or monitoring specific to the study drug or needed just for the clinical trial? Covered by the sponsor of the trial, not billed to insurance.

The second bucket is things that are billed to the patient’s insurance and those are things that are routine, standard of care. If someone has lymphoma, they’re going to be seen by their physician routinely. Their labs are going to be monitored. They may need to be hospitalized for treatment or symptoms. Those are all billed to insurance because even if a patient wasn’t participating in a clinical trial, they would still be having those physician visits and having their labs checked routinely.

The third bucket is things that come out of a patient’s pocket like the general copays that you would have and travel and lodging to a site. If you needed to travel far away from home to participate in a study, that would be considered out-of-pocket for a patient.

Misconception #3: Clinical trial as last resort

Crissy: The other misconception that I hear quite frequently is that patients think that they can only participate in a clinical trial if they’ve exhausted all of their treatment options and that could not be further from the truth.

There are clinical trials for patients in every step of their diagnosis — from the time that they’re first diagnosed, all the way through having failed multiple lines of prior therapy. There’s a clinical trial for most patients at every stage of their treatment.

This could be standard of care, front-line treatment for a patient with another added drug to see if it makes it more effective. It could be things like studying CAR T in the front-line setting where half of the patients get front-line treatment like R-CHOP and half of the patients get CAR T to see if CAR T is more effective in front-line treatment. Then every step beyond that, including long-term monitoring for patients who are in remission.

The Latest in DLBCL Treatments - Clinical Trials

What is CAR T-cell therapy?

Stephanie: We’d like to delve into CAR T a little bit more. We have been getting a lot of patient questions.

Dr. Brody, can you give us a general description of CAR T-cell therapy? What is it? What does it entail?

Dr. Brody: When I describe CAR T cells to my patients, they think I’m kidding. It sounds like science fiction, but it’s a real thing. They think, “Oh, what decade? When will that be here?” It’s already here.

CAR T-cell is a combination of gene therapy and immune therapy. We take out some of a patient’s immune cells, send them somewhere where they turn them from normal healthy T cells, and insert this new gene called CAR, a chimeric antigen receptor. Now we call it CAR T cells.

They ship the CAR T cells back to you. The patients have to get some chemotherapy before the CAR T cells are reinfused. We say we give that to make room for the new cells to come in. It’s a bit of a metaphor, but it’s conceptually fair.

The gene that we put in, CAR, helps those T cells to go to your diffuse large B-cell lymphoma and eliminate it more potently than any other single therapy that we’ve ever developed. Close to some other immunotherapies now, but it’s quite amazing.

The Latest in DLBCL Treatments - Clinical Trials

They don’t do it perfectly and they don’t do it for 100% of people, but they induce remissions in a good majority of people. Depending on the setting, they may cure 35, 40, or maybe even 50%, but we usually say about 40% of patients. Again, it depends on what’s happened to that patient before and some other things about the patient.

For Dr. Stacy-Humphries, we used to call that an incurable setting — third-line, diffuse large B-cell lymphoma — and now we’re curing 40% or more of those patients. It’s miraculous and it’s not science fiction. It’s a real thing.

Robyn’s CAR T-cell therapy experience

Stephanie: Robyn, you went through this. You’re a physician so you have, I think, more of a know-how of navigating ClinicalTrials.gov or understanding what’s in the pipeline. How did you determine that this was what you wanted to do? You mentioned it was a leap of faith. Who brought it up? What was the experience like when you actually went through CAR T?

Robyn: I decided that I want to do CAR T because I didn’t have an allogeneic match. I could have had a haploidentical transplant, which is a half-match with my son. I didn’t do well with the autologous transplant so I didn’t think I was going to do well or I may not have survived an allogeneic transplant and I may not have had a normal life. I wanted to have that quality of life.

I’d read about CAR T in some scientific articles. I just Googled this. Nobody really told me anything. I just thought this made sense because right now, the basis of cancer therapy is you either cut it, you burn it, or you poison it. Taking your own immune cells is actually much nicer. It’s lovely as compared to the other ones, even though it has side effects.

When I researched clinical trials, I didn’t have that much of an insight. I just put in my diagnosis. I found all of the trials and we emailed every single investigator.

The reason I ended up in the trial was it was the only opening that existed. We looked all over the world. I was really ready to sell the house and move wherever. We were lucky to get one about nine hours away.

Fast forward, I signed up for CAR T. I’m the second person at this huge hospital who gets the treatment. When they took my T cells out, they gave me one chemotherapy agent, bendamustine — some people get FluCy — and had the CAR T cells infused. The infusion took about five minutes. Everyone in the room clapped and just left so it was very anticlimactic.

In my case, they started working very quickly. By the time I came in, I had a lot of lymph nodes and within 24 hours, they started melting. Within seven days, all my palpable lymph nodes were gone.

I developed cytokine release syndrome. In my case, it was a fever and low blood pressure. Most people feel really lousy, like the worst case of flu ever. I was hospitalized for three days from days 5 to 8. Other than that, I was in a rental condo and stayed at the hospital for a month. I didn’t feel great, but I didn’t feel awful.

Amazingly, I was able to go back to work four weeks later, only working two days a week, which is unusual. I did extremely well and I would say that that’s relatively unusual. I know a lot of people now who had CAR T who were working two weeks after.

Dr. Brody: After the stem cell transplant, how long were you out of work? Just for comparison.

Robyn: I was out of work for three months and when I went back to work, I was not able to eat solid food. I lived off smoothies. It was terrible.

Stephanie: What a comparison. You also said you were young and otherwise healthy except for the lymphoma so all these things may factor into a response.

Pros & cons of CAR T-cell therapy

Stephanie: Patient Gil R. asks, “What are the pros and cons of CAR T-cell therapy and what is its duration?” Dr. Brody, I think you can answer this question in several ways, but I think in talking about pros and cons, people want to compare. What are the side effects? In terms of duration, how long is the therapy itself and how long is the expected duration of response?

Dr. Brody: Pros and cons, very broadly.

Pro, if you compared it to what Dr. Stacy-Humphries described as the old standard before that, the chemo and stem cell transplant, CAR T cell therapy is both more effective, especially for some patients, and gentler. Robyn was out of work for 2 to 4 weeks, whereas after the transplant she was out of work for months and only on smoothies.

When you ask doctors about efficacy, we can give you numbers. When you ask about side effects, we describe them in more nebulous, vague ways because there are so many numbers you could give.

A great metric is how long were you out of work or unable to do the things you do. If you’re retired but you garden every day, how many weeks or months until you are gardening again? Those are great examples.

Let’s acknowledge the cons as well and Robyn pointed out one. Some of the side effects and the most common and one of the scariest ones is CRS, cytokine release syndrome.

It’s basically like having an infection, but there’s no infection there. You have fevers and sometimes dangerously low blood pressure. Even though Robyn was only hospitalized for a few days, the more common thing nowadays is folks are hospitalized for sometimes a couple of weeks on average.

Sometimes, it’s a boring hospitalization, which is the best kind of hospitalization, just to watch for that side effect to see if it occurs. Sometimes folks have to go to the intensive care unit just to treat that low blood pressure and fever. That is one of the biggest side effects.

The Latest in DLBCL Treatments - Clinical Trials

One other scary side effect is called ICANS (immune effector cell-associated neurotoxicity syndrome) but we just call it neurotoxicity or encephalopathy. It means there’s a horrible problem with the brain and this side effect manifests in many different ways like hallucinations and loss of consciousness.

These things sound very scary so I should preface it by saying there’s a very defined time course to these side effects. They almost always happen within the first couple of weeks. There are a couple of rare exceptions of it happening on the third week, but they never happen two months later. Both CRS and neurotoxicity are scary side effects. They’re time-limited for the majority of people, but they’re a serious big deal.

Some patients have a higher risk of getting those side effects, like patients who are older or less healthy and patients who have greater tumor bulk. Patients with enough lymphoma have more of those side effects than patients with just a small amount of lymphoma when they go into CAR T therapy.

This therapy has a greater track record of keeping people in remission for years and years. We have some newer therapies that are as promising, but they don’t have the years and years of track record because they’re newer therapies.

These side effects are not nothing. If you were an 80-year-old patient with a bulky tumor, these cons are a serious thing and we have to start thinking about other alternatives for those kinds of patients.

What are bispecific antibodies?

Stephanie: Dr. Brody, let’s talk about bispecific antibodies. Some have described it very simplistically as an off-the-shelf CAR T option.

Dr. Brody: This is, I would say, the most exciting and transformational thing in lymphoma and DLBCL, certainly in the last couple of years. Maybe you might argue ever because my belief is their total impact in the next few years is going to be unparalleled.

Antibodies are magical little molecules, big long proteins that bind very specifically to one thing. We make antibodies against COVID after we get a vaccine or get COVID.

A company can make antibodies against certain targets on lymphoma cells. Rituximab is an antibody against lymphoma, but it just binds lymphoma.

Some brilliant pioneers from a few groups developed bispecific antibodies. They bind to lymphoma cells and one of your T cells.

Some people use the Lady and the Tramp with one spaghetti noodle metaphor. If you haven’t seen the movie, the spaghetti noodle brings them together except instead of the kiss between the Lady and the Tramp, this is the kiss of death because the T cell kills the lymphoma cell and kills it pretty well.

In a way, it’s sort of an off-the-shelf version of a T-cell therapy, like the CAR T cell. It’s very cool that CAR T-cell therapy is individualized. I send my T cells in, they send me back my CAR T cells. Logistically and practically, it’s very difficult and it takes a lot of time.

How much time it takes is a bit variable. It could take 2 or 3 weeks to make the product, but sometimes it takes a couple more weeks just to plan the whole thing out. Sometimes it takes more weeks just to get to see the doctor to plan that so there can be real delays there.

Whereas with these bispecific antibodies, you just inject it right into the patient. No delay there so they are in some ways a lot easier because they are off the shelf. You don’t have to make it for each person.

Efficacy of bispecific antibodies

Dr. Brody: The efficacy has been overall awesome. They are not perfect, but they are putting a big proportion of patients into complete remission and some of those patients are staying in complete remission for years so that’s fantastic. Maybe the numbers are a little less amazing than CAR T cells in efficacy, but they’re also a lot easier.

The Latest in DLBCL Treatments - Clinical Trials

Side effects of bispecific antibodies

Dr. Brody: Overall, possible side effects are a lot gentler. Those CAR T cells were causing CRS or neurotoxicity in maybe 10 and 20% of patients, whereas these bispecifics caused bad side effects in maybe 1 to 3% of patients.

It opens up a lot of opportunities. A patient that was not eligible for CAR T, because it would have been too scary, could be eligible for bispecifics.

Access to bispecific antibodies

Dr. Brody: CAR T cells are available at a limited number of centers. That can be tricky because you’re not just going there for one day to get the therapy; you’re there for a while, as Robyn was saying.

Bispecifics were just FDA-approved so they may not be available everywhere today. We don’t want to oversell that, but they can be available everywhere and they’re now available at most major centers.

Eligibility for bispecific antibodies

Stephanie: Epcoritamab and glofitamab are newer and newly approved.

How would someone know what questions to ask whether they’re a good candidate for bispecifics or which option to go for? As we know, it was approved for later lines of treatment and even after approval, they’re still in clinical trial because everyone likes to try and move it up earlier in lines of treatment.

The Latest in DLBCL Treatments - Clinical Trials

Dr. Brody: Very exciting. These two medicines were just FDA-approved. There was one other that was approved for follicular lymphoma at the end of 2022, which was mosunetuzumab.

There are a lot of these getting studied and approved now. There will be several more approved as sort of a plan C, third-line therapy when Plan A or Plan B don’t work well enough.

If a patient asks, “Is this the right therapy for me?” Tough and detailed question, but the first thing you want to make sure of is that the doctor that you are working with is familiar with the option.

Even though they are available anywhere, there are a lot of new cancer medicines coming out every month and year. This is very tough, especially for community oncologists who take care of every kind of cancer. It would be impossible for them to be super familiar with every new medicine for every type of cancer.

It is not that every patient with lymphoma needs to be seen by a lymphoma specialist, but once Plans A and B have failed, this is not a great situation.

Let’s just be simple about it. Bluntly, it is worth the schlep to go and see a specialist who does nothing but take care of lymphoma patients. They are familiar with these medicines and it would be hard for most community oncologists to be familiar with them.

Community oncologists will be familiar with these medicines over the next couple of years, but they may not be today and they may not have access to administer them because there can be complexity in getting these medicines started in a new practice.

You need to make sure that you’re speaking with a doctor that has comfort around this. A lot of times, community oncologists are vaguely aware of it so they’ll call their local buddy who’s a specialist and say, “You tell me. Should I send this patient to you?”

But as you heard from Robyn, sometimes patients end up advocating for themselves. I’d like to say that there’s a better way, but that does happen. The function of The Patient Story, the LLS, and other patient advocacy groups is to try to be an intermediary so patients don’t have to advocate for themselves.

But if a patient is asking if bispecific antibodies are right for them, there’s a good chance the answer is yes so you should at least be talking to someone that has experience with these.

Choosing among treatment options

Stephanie: When there are different options and they’re new, how do you make a decision on which option to put a patient on?

Dr. Brody: Although these medicines are newly approved, we’ve been using these medicines for three years, give or take, so we have a lot of familiarity with them. Maybe we didn’t predict this, but epcoritamab and glofitamab are more similar than different.

For example, the complete remission rate for both of them was exactly 39%. What are the chances of that? The high-grade bad side effects were about 3% with both of those medicines.

There are a few nuanced differences. Epcoritamab is given subcutaneously whereas the glofitamab is given intravenously. It’s a little difference, not a huge, big deal.

The timing is a bit different. Epcoritamab has more visits and they might go on for longer. Glofitamab has fewer visits and is designed to be stopped after about nine months.

It doesn’t give you an answer to which one is better. We ultimately make a decision for each patient, but they’re pretty similar overall.

The Latest in DLBCL Treatments - Clinical Trials

Stephanie: Let’s bring back CAR T. There are different approvals for different groups of people and there has to be that personal conversation between a patient and the provider to understand the best option.

Generally speaking, if you’re comparing CAR T-cell therapy versus bispecifics in terms of limitations and challenges, what would that summary look like for our patient audience?

Dr. Brody: I’m going to change the question slightly. The question is always which one’s better, CAR T or bispecifics? But that’s not actually the question people really care about because, unfortunately, neither of these cure 100% of people. As the patient, you want to get access to both, not A or B. You might want both this and that or that and then this.

The best question is: what’s the best order to give them? If you were going to get both, would you rather get CAR T and then bispecifics or bispecifics and then CAR T?

Sometimes it’s a moot point because CAR T is approved as a second-line therapy for some patients and so far, bispecifics are approved as a third-line therapy for patients. In some cases, you don’t have to make a choice because this one’s available and that one’s not — that’s going to change a lot in the next couple of years.

I have to give you my honest belief about this. CAR T has one thing that is definitely better — they have a longer, more tried, and true precedent of keeping people like Dr. Stacy-Humphries in remission for a long time. We say “curing” patients. It’s been proven for longer so you might want the most proven thing and CAR T is that.

It still fails for a majority of patients depending on the setting. If it cures 40%, that means there’s 60% that still we need to do better for.

The Latest in DLBCL Treatments - Clinical Trials

If you really want to get both, if you were to get CAR T and it failed, you might not be able to get bispecifics because the chemo you get right before CAR T might not make the bispecifics work well. It wipes out many of your own immune cells so giving them in that order may not be great. Giving CAR T and bispecifics right afterward may not be a good option.

If you give bispecifics first and you’re in remission, great! You don’t need something else. But if they stop working, then you could get CAR T afterward. We’ve done that many times now.

It’s not which one is better; it’s what’s the best order to get them if you’re going to get both. For some situations, it’s going to be CAR T. There are a lot of situations for which you might want to get bispecifics first also because it is gentler and the risk of those bad side effects is lower. Some people find that appealing as well.

There’s no right answer, but I’m giving you a little bit of my prejudicial belief about what might be the best order.

Stephanie: Sequencing is a huge question. If bispecifics are approved for earlier lines, it will actually be a consideration for people.

Bispecific antibodies in the community setting

All things considered, part of the question, too, was accessibility. There’s this idea that if it’s off the shelf, more people will have access to it. Do you see any challenges there, even in the community setting, with bispecifics? What are some of the solutions?

Dr. Brody: I was explaining how much easier and gentler bispecifics are compared to CAR T cells. Robyn actually had a good experience, but she did have cytokine release syndrome and people do have to get hospitalized usually for that. Sometimes, for only a few days but most commonly for a couple of weeks.

Bispecifics are gentler. The risk of high-grade side effects is less, but there is still a 3% risk.

As of today, folks getting bispecifics still have to get hospitalized for at least one day just to watch them as they get the first dose of that new medicine. That’s not so bad. One day is less than a couple of weeks, but it’s not nothing.

Some community oncologists may have difficulty getting that hospital bed lined up. It sounds like a simple thing, but practically, it can still be difficult. We are trying to overcome that obstacle.

There’s an ongoing clinical trial of epcoritamab trying to give it at a gentler step-up dosing so patients don’t even have to get that one-day hospitalization. There’s a good chance that the trial will be successful so we’re looking forward to that.

But as of now, even getting a one-day hospitalization might make this an obstacle to getting this with your local oncologist.

Bispecific antibodies as a treatment option

Stephanie: Robyn, you lead this huge group online in the CAR T-cell therapy space. I’m curious if you’ve started to get questions about bispecifics. What is your take on where you think bispecifics might fill a gap or be a good option for folks?

Robyn: Every patient is unique. In community hospitals, most oncologists are very overwhelmed with trying to take care of more of the “bread and butter” type of therapy so I really don’t see bispecifics going into the community hospitals anytime soon, at least in the more rural areas. It’s going to have to be in a city center and often on a transplant unit.

For bispecifics and CAR T, I see them as very similar. On the CAR T site, we do have people who fail. About 40% have a long-term remission rate then there’s everyone else.

Most people after the second or third round should see a lymphoma specialist then they’ll have to decide what they would rather have or what’s best for them. With the new bispecifics, it changes the whole gamut.

Most of the people on the site are actually CAR T, but then when people fail, there’s another site that deals with relapses from CAR T. A lot of those patients go on to bispecifics and they’ve had some real success with that.

Everything’s very early. Patients need to be their own advocates and have to be honest. As much as they would like to stay in their rural hometown or be with their family doctor, if you have something serious like this, you really have to travel.

New DLBCL clinical trials

Stephanie: Dr. Brody, there are different clinical trials that are happening that we haven’t covered, but as great as these developments are, everything has some limitations. There are always more clinical trials to try and solve those problems. If you could talk a little bit about some of the newer clinical trials that are happening and what problems they’re trying to solve, especially in the bispecific space.

Dr. Brody: Rituximab targets CD20 and these bispecifics so far also target CD20, a marker that’s on lymphoma cells. The CAR T cells target another thing on lymphoma cells called CD19. There are a few of those markers that you could maybe target.

If you target something on the surface of lymphoma cells, if there were a couple of lymphoma cells that didn’t have CD20 or CD19 on them, those won’t get targeted by the therapy and would grow out, escape, and cause the relapse.

We call this antigen escape when that targeted antigen is lost by the cancer cells and then those cancer cells grow back. This is the main limitation of both CAR T cells and bispecific antibodies so there are a lot of ways we could try to solve this problem.

One of the simplest ones is to go after different targets. We now have bispecifics targeting another antigen on lymphoma cells called CD22. The numbers don’t even matter that much. It’s just going after something that wasn’t on the cancer cell initially so they’re still there after the first bispecific.

We have things beyond bispecifics called trispecifics, which are going after two things on the lymphoma cell and then getting the T cell. For example, going after CD20 and CD79 and then grabbing the T cell as well, the effector that’s going to give the kiss of death to that lymphoma cell.

These are good ways to prevent the antigen escape problem. We’re starting some of those trials now. We’ve been treating a lot of people and seeing patients going into complete remission so maybe these will be even better than the already standard of care that was the cutting edge just a month ago, the new bispecific antibodies.

Maybe we’ll have trispecific antibodies as the new standard of care to prevent that problem. Some limitations but some solutions coming up for those limitations so pretty encouraging.

Different phases of clinical trials

Stephanie: Crissy, a lot of your patients get worried when they hear that one of the studies is in phase 1.

Crissy: I hear that a lot. Patients call me and say, “I only want to participate in a later phase trial like a phase 3 or a phase 4.” There’s a long conversation that goes into explaining to patients that a drug doesn’t go through all four phases of a clinical trial before it’s approved.

Phase 1 clinical trial

Crissy: A phase 1 clinical trial is a dose-finding clinical trial where they find the proper dose and establish safety. How that’s done is in a step-up fashion. Generally, there are a couple of dose levels that are identified and they enroll a small number of patients into each dose level.

They start with dose level one and give that dose to around three patients. They assess those patients and monitor for toxicity for a set number of days, usually more than a month. If no unwanted toxicity is seen, they move up to the next dose level and beyond in that same fashion.

They move up to dose level two, give that to a small number of patients, and assess them for toxicity. If there are no unwanted toxicities, they move up to the next dose level. Same thing. A small number of patients monitor them for a period of time.

Phase 2 clinical trial

Crissy: Once they’ve reached either the maximum dose in the trial or toxicity, that dose level is identified and moved into phase 2. They give the dose level that was identified in phase 1 to a large number of patients in phase 2, usually around 100 patients. That’s when they’re assessing for effectiveness.

If you look at the way a clinical trial is listed on ClinicalTrials.gov, many clinical trials are listed as phase 1/2 and that design that I described is being done on the same clinical trial.

Sometimes, after phase 2 is complete, if the data is robust enough, they’ll submit to the FDA for approval at that point. Sometimes clinical drugs only go through phase 1 and phase 2 before being submitted to the FDA. However, a phase 2 clinical trial is considered the gold standard before being submitted to the FDA for approval.

Phase 3 clinical trial

Crissy: In a phase 3 clinical trial, drugs are being compared to the standard of care. A really good example of this is after CAR T was very first approved, it was only approved for patients who had lymphoma and had failed two or more lines of therapy. The FDA approved it for patients who had failed front-line treatment and then either salvaged with an autologous stem cell transplant or just salvage therapy alone.

A phase 3 clinical trial opened up where CAR T was compared to the standard of care second-line therapy. Half of the patients received CAR T and half of the patients received standard of care with an autologous transplant.

Phase 4 clinical trial

Crissy: A phase 4 clinical trial is long-term toxicity, side effect type of trial for drugs that are already on the market.

Low enrollment for adult clinical trials

Stephanie: This is where the LSS’s Clinical Trial Support Center can help. Can you explain more about the numbers that you’re seeing? The national enrollment for adult clinical trials is very low and the LLS is trying to get the numbers up.

Crissy: Many patients come to us having tried to look for clinical trials on their own or a doctor told them to look for clinical trials or they had a loved one who just decided to start looking for clinical trials on their own. They often come to us very overwhelmed, having tried to look at ClinicalTrials.gov or other databases for clinical trials.

You can certainly go on to ClinicalTrials.gov and look for trials yourself. What our department does is take that workload off of a patient and their families and do a personalized search for the patients that we work with.

The national average of patients that participate in clinical trials is around 3-5%. Nurse navigators in the Clinical Trial Support Center help patients identify clinical trials that they’re potentially eligible for, identify barriers that they may be facing — logistical barriers, insurance barriers, not knowing what options are available — and overcome those barriers.

Our average of patients that participate is around 22%. The patients that we work with have a higher chance of participating in clinical trials because of the work that we do to help them navigate the entire process.

On behalf of the patients that we work with who participate in a clinical trial, our nurses do more than 20 interactions with healthcare providers or the trial sponsor. Our team and LLS in general really look at that as more than 20 opportunities for a patient to fall through the cracks if they weren’t working with a nurse on our team.

The Latest in DLBCL Treatments - Clinical Trials

Travel costs in clinical trial participation

Stephanie: Patient Joy B. asks, “Are travel costs included for clinical trials?”

Crissy: Very good question. Around a quarter of clinical trials close because they don’t reach accrual goals. They have a set goal for how many patients will participate in the trial and they don’t reach it.

One of the reasons that happens is that while clinical trials are at academic sites, patients aren’t always located near an academic site so they have to travel to participate.

A lot of work has been done over the last 5 to 10 years to overcome that barrier for patients. If they have to travel to participate in a clinical trial, how do we decrease the burden for them with that travel? And that’s been identified as financial assistance.

A lot of clinical trials will provide financial assistance to patients who participate in a trial that has to travel beyond a certain distance. Generally, it’s more than 30 or so minutes.

If a patient has to travel more than 30 or so minutes to participate in a clinical trial, I highly, highly encourage them to ask the team at the treatment site if there is financial assistance for me to participate. Oftentimes there is.

The Latest in DLBCL Treatments - Clinical Trials

How it looks is different for every clinical trial and every site. Sometimes it is a concierge service that books patients’ travel or lodging for them. Sometimes it’s a prepaid card that helps them pay for the hotel, food, and gas.

Other times, in not-so-ideal situations, it is done on a reimbursement basis where patients submit their mileage, food receipts, and lodging receipts then they’re paid back by the company for those expenses.

There’s been a lot of advocacy from LLS and other groups to change that model. A lot of patients don’t have the money to front that. If they can’t pay for a hotel room upfront, the reimbursement model doesn’t work for them.

Additionally, The Leukemia and Lymphoma Society has copay assistance and travel assistance for patients, whether that’s to get treatment or to participate in a clinical trial.

Clinical trial paperwork

Stephanie: Robyn, you went through this process. I would love to hear about figuring out logistics, but also you had to go through excessive paperwork before the clinical trial, is that right?

Robyn: The paperwork is very intimidating for most people and even for myself. Look through the paperwork but also talk with your doctor. The paperwork always has the worst things that can possibly happen with the clinical trial, but you also need to ask your doctor, “What is the alternative that I’m getting?” A lot of times, we don’t go into that.

For example, CAR T versus allogeneic transplant. People get a little overwhelmed. Sometimes, they don’t understand that the clinical trial has some risks but even the standard therapy might even have more risks.

Ask questions. Try not to get too overwhelmed with the paperwork. Be your own advocate. Knowledge is power. Read up and be ready to go. Don’t expect all your doctors to have all the answers right off the bat. You need to be able to ask the right questions.

Crissy: If I had the time like a day or so of leeway, I would call the patient ahead of time, get their email address, and send them a copy of the consent form beforehand.

I would tell them, “Look this over with your family. Highlight, write down questions, and make a list of questions that you have about the form before coming to the site.” It’s a long form; oftentimes over 50 pages and that can be a lot in a single doctor’s visit to look over.

Bring someone with you. That can be a village. If where you’re going allows, bring people with you for that visit or have them on video call so there are more ears hearing the information and people who can remember the information.

Lastly, the really important thing is you can sign that form and say that you want to participate, but it’s not legally binding. You can leave the clinic that day and say, “You know what, I changed my mind. I don’t want to participate.” You can do that at any point in the clinical trial — a day later, a week later, months later.  You’re not legally bound by any means after signing that form.

I encourage patients to stay on the trial if possible. For data capturing purposes, we need patients to stay on the study to show the effectiveness or safety of the drug so that it can potentially get to many more people.

Stephanie: I love that message of self-advocacy. What we’ve seen at The Patient Story is people get motivated when they hear other people say, “I was an advocate for myself.” It almost gives a sort of permission to speak up.

Final takeaways

Stephanie: We’d love to understand the final takeaway from each of our panelists that they’d like for audiences to walk away from. Dr. Brody, what’s your biggest message?

Dr. Brody: Patients with lymphoma are unlucky to have lymphoma but so lucky to be here today with that lymphoma. Twenty years ago, we didn’t have access to medicines that cure patients and keep them in long-term remission to go and live their lives, hopefully just like they were before.

We only have those new medicines because patients join clinical trials. Patients who join clinical trials today sometimes are getting access to the medicines of the future.

These new bispecifics that just got FDA approved, our patients were getting access to them three years ago because they did this slightly scary thing and asked, “Are there any clinical trials available?” For some of them, thank goodness, because they’re still here to tell their story today.

Stephanie: Thank you, Dr. Brody, for being a leader in the space of clinical trials. We also know what a big advocate you are for patients and their families so thank you so much.

Crissy, I know that for you, there’s something about when to talk about these options with people’s doctors, right?

Crissy: Around 90% of adult patients with cancer are treated at community sites. The bulk of clinical trials, unfortunately, are not at community sites. They’re at large academic centers.

From the time a patient is diagnosed, they may not know that there are clinical trial options available to them if they’re not at the site where a patient is being treated. Generally, physicians are going to offer patients what they have at their site.

It’s really important to talk to your doctor. Ask them from the point of diagnosis and at relapse and beyond: What are all of my options beyond the treatment that you’re offering me here? Is there something that’s potentially better or other options that I could access somewhere else?

You’re the driver of your ship and so advocate for yourself. Ask questions. From the time you’re diagnosed, ask about the treatment options that are available to you now and what if. What’s our plan B? If this treatment doesn’t work, what’s next for me?

Explore second opinions. If you’re interested, go to another site and see an expert in your disease and ask what they would recommend to you. There are no ill feelings from a healthcare provider when a patient wants to see another physician in that space and get their input.

For patients who come to me worried that they’re going to offend their doctor, you’re generally not. The grand majority of physicians are not going to be offended if you want to get a second opinion from an expert in the field.

If you are with a physician who is offended by you getting a second opinion, that isn’t a physician I would personally want. I want a physician who wants their patients to advocate for themselves to know all of their options and explore every option that’s available to them.

Stephanie: Thank you so much, Crissy, for that and for your work at the CTSC. Patients and family members find a lot of comfort for sure in having someone to lean on through what can be a very overwhelming process so thank you again.

Speaking of this process, Robyn, you are such an inspiration for people about the power of a clinical trial. We know that it might not be for everyone and it’s a very personal decision, but you have such a wonderful voice to lend when it comes to what is right about a clinical trial.

Thank you also for participating in one because that helped to further the data and the experience so that it could lead to approval. You’re proof of thriving after a trial. What would you like your message to be to our audience?

Robyn: Don’t give up hope. Make sure you ask questions. Feel free to get other opinions. Really good doctors are not insulted when you get another opinion.

I’m living a great life. I’m working. I’m traveling. I saw my youngest child get married. It’s fantastic.

I’ve been a doctor for over 30 years and I’ve taken care of a lot of patients. I’ve read hundreds of thousands of films. I’ve done thousands of biopsies. I’ve held a lot of people’s hands. I’ve counseled a lot of people. But ironically, my biggest contribution to medicine is not as a doctor, but it’s been as a patient so I’m grateful to be here.

Thanks, Stephanie, for doing this. This is fantastic. I wish I had had something like this when I was going through my experience.

Stephanie: Thank you so much, Robyn, Crissy, and Dr. Brody — incredible discussion about clinical trials in the space of DLBCL. We hope you’re able to walk away tonight knowing more and feeling more comfortable about what clinical trials are.
