Transcript:

CAR T-cell therapy has revolutionized care for people with myeloma in recent years. This treatment is an innovative form of immunotherapy that modifies the patient’s own T cells to target and destroy cancer cells. While there are FDA-approved CAR T-cell therapies for myeloma, ongoing clinical trials are helping to expand this therapy’s use.  

If you or a loved one is considering participating in a CAR T-cell therapy clinical trial, these questions may help guide your conversations with your doctor and support decision-making: 

  • Am I a candidate for any CAR T-cell therapy clinical trials? 
  • How do the potential benefits compare to my current treatment options? 
  • What side effects should I expect if I participate in the trial, and how will they be managed? 
  • What phase is the study, and how might it impact my care? 
  • What is the time commitment involved, and where will the trial take place? 

When deciding whether or not to participate in a CAR T-cell therapy clinical trial, it’s crucial to weigh the pros and cons with your healthcare team to determine if this approach aligns with your treatment goals. You should also discuss your options with a care partner, such as a friend or family member.  

Before enrolling in a trial, consider these factors: 

  • Ensure you have a reliable care partner to assist you during and after treatment. In most cases, a care partner is required for patients undergoing CAR T-cell therapy. 
  • Understand the costs involved. For some trials, the sponsor may cover a portion of the cost. Ask about financial resources that may help with participation, such as transportation or lodging assistance. 
  • Be sure to review the informed consent process carefully. This form will outline the trial’s purpose, potential risks, benefits, and your rights as a participant. 
  • And you should understand that participation in a clinical trial is voluntary. You have the right to leave the trial at any time, for any reason.  
  • It’s also a good idea to understand what to expect before, during, and after the clinical trial process. Taking steps to prepare for life outside of treatment can be highly beneficial, and can support positive mental and emotional heath. 

Taking part in a CAR T-cell therapy clinical trial offers a unique opportunity—it could provide access to advanced therapies and support critical cancer research. Reflect on how trial participation fits in with your personal treatment goals, and be sure to include your care partner and healthcare team as you make decisions.  

Remember, it’s important to stay proactive and informed. Whether you join a CAR T-cell therapy clinical trial or explore other treatment options, make choices that prioritize your well-being and support your journey forward.

Understanding Myeloma Therapy Targets BCMA and GPRC5D 

Transcript:

Katherine Banwell:

This one is from Jennifer. Why do CAR T-cell transplants not last longer? Is it possible to do a second transplant if the first CAR T transplant stops working? 

Dr. Rahul Banerjee:

It’s a great question. So, it’s an excellent question. So, the only thing I would say semantically is, right, in my head, CAR T cells are not transplants per se, because I’m not changing the bone marrow. So, I would transplant a stem cell transplantation, separate from CAR T.  

Why do CAR T cells stop working? So, the short answer is we can speculate. We don’t know for sure for any individual patient. Three different buckets are involved. Three different things can happen. One, the T cells can stop working or disappear from circulation. So, that’s possible. CAR T cells don’t last forever. That’s actually okay, right? People often wonder like, “Man, I wish the CAR  
T cells could last forever.” I don’t know that I’d want that because as I alluded to, for as long as the CAR T cells are there, patients are immunocompromised, and so that can certainly interfere with the quality of life.  

So, it’s not necessarily true that the CAR T cells need to be there forever, but if they’re not there, or if they’re exhausted, which is actually a true scientific word for them not being able to activate and kill that cell when they recognized a protein, the BCMA, that’s one problem.  

The second problem is the myeloma cells can mutate. I alluded to this briefly earlier, where the cells can learn to shut off the protein, BCMA, or they can mutate the protein in just a way that the  
CAR T is no longer able to bind.  

And the third is something called the tumor microenvironment. And this is a little bit more complicated, kind of a grab bag of different things here. The idea is that myeloma cells have a lot of tricks, and they can use all of the cells around them to make it hard for the CAR T cells to get in, to get into the bone marrow and kill them all. And the T cells can be shut off before they even get there.  

So, it’s one of those three things in general. Which one is it for an individual patient? Hard to say. And so hopefully in the future, we’ll have better diagnostic tests to be able to identify who is a patient where another BCMA targeted therapy would work well versus, “Oh no, these myeloma cells are no longer expressing BCMA, let’s move on to a different target like GPRC5D.” We’re not there yet. We’ll get there hopefully in a couple of years, is my goal.  

Then, you know, Jennifer, that’s a good question. Well, can we do a second CAR T? And that’s very practical. What I would say is if the first CAR T therapy did what we expected it to do, if it lasted for as many years as I would expect for Abecma, that’s typically 12 to 18 months. For Carvykti, that’s typically over 24 months.  

If it worked and then it stopped working, and then probably the T cells are long gone, it’s reasonable to try CAR T therapy again. In general, I would recommend, I strongly recommend a different CAR T-cell therapy, even if it’s targeting the same class, like BCMA, it’s going from ide-cel (Abecma) to cilta-cel (Carvykti) or vice versa. 

The risk with giving the same CAR T-cell product again is that even though the T cells are a patient’s own T cells, the protein is slightly foreign. Abecma was derived from decades of mouse research. Carvykti was made from decades of llama research, believe it or not. Again, there’s no mouse or llama involved with the actual products nowadays, but in making the sequence years ago that came to them, they are foreign. There are foreign sequences on them, and so everyone’s host immune system eventually recognizes these cells as foreign.  

And so if you were to give the exact same product again, immediately the body would reject it the second time around, because it recognizes them and has learned to recognize it as foreign. But changing to a different CAR T cell is very reasonable. 

And again, for these newer GPRC5D targeted CAR T cells that, again, don’t target BCMA the way that Abecma, ide-cel or cilta-cel, Carvykti do, but target a different protein entirely, for those patients generally there’s no restriction on whether they’d received a prior CAR T cells. Ideally, it should be at least several months away, at least like a year or so, but if that’s happened and they stopped working, very reasonable. In fact, some of the trials actually require that patients going on to the study of a GPRC5D product have had a prior BCMA therapy of some sort before, and so they’re kind of built into the architecture of things. So, I think it’s very reasonable.  

Obviously, there are some unknown unknowns, right? What do you do if the T cells are being manipulated twice, so to speak. Patients ask me about that. I will say just to put that fear to rest, in general, by the time that someone’s had myeloma come back after the first CAR T cells, I alluded to this, the CAR T cells are long gone. So, there’s nothing left.  

But again, every case is different, and future research will help us kind of figure out how best to do this. 

Myeloma CAR T-Cell Therapy | How Is Success Measured?

 

How do you know if CAR T-cell therapy is working? Dr. Rahul Banerjee, a myeloma specialist, discusses how a patient’s response to CAR T-cell therapy is monitored and the role of measurable residual disease (MRD) in patient care.

Katherine Banwell:

Well, how is success measured for CAR T-cell therapy? 

Dr. Rahul Banerjee:

It’s a great question. So, traditionally, the metric in multiple myeloma has been achieving a complete response. So, having the M-spike, the antibodies that are produced by the myeloma cells, come down to zero. 

So, either the M-spike, or for some patients, that may be the kappa or the lambda, which are fragments called light chains of antibodies, coming down to the normal range. The hard thing about those is that they take time. I’ve had patients who get CAR T therapy, and their bone marrow is completely clear, including MRD, measurable residual disease, as I’ll talk about in a second, but the M-spike takes months. 

I had one patient where it took a year and a half for the M-spike to finally come down to zero. And it’s frustrating because I would say that, look, in my heart, you’re in remission, but if I were a lawyer, I wouldn’t be able to say that, because technically the M-spike is not quite zero yet. Your body’s just recycling that antibody. It’s not all the way down to zero, and that makes things tough. So, I don’t think that’s a great barometer to use.  

I think MRD, which is again, a bone marrow test that we can spend more time talking about another day, is helpful. And at the one-month mark, achieving MRD negativity.  

So, if you look in the bone marrow, by all the best tests available in the United States in the year 2024, and you can’t even find one out of a million cells that are myeloma, that’s obviously great to see.  

That doesn’t mean that if it doesn’t happen, the patients are going to do poorly. There’s a lot more to CAR T than that. So, I think MRD negativity is probably the best short-term barometer. I think the best long-term barometer would be progression-free survival, which is, again, the medical word of saying how long is someone alive and in remission for. 

CAR T-Cell Therapy for Myeloma | Challenges and Unmet Needs

Transcript:

Katherine Banwell:

CAR T therapies have been in use for several years now. As a clinician, what challenges are you facing with this treatment option? 

Dr. Rahul Banerjee:

Absolutely. So, I would say threefold, is the best way to describe it. So, I think the first and most practical, like the most important one is obviously access. It’s very easy for me to talk about CAR T therapy. I had the privilege of working at a big center, where I was just last week attending on our CAR T service. We’re big enough to have a CAR T service. 

Most patients are treated in the community, and they don’t have access to a doctor who’s personally familiar with CAR T. And so for them to get to CAR T requires a move to a big academic center, a big tertiary care center. Obviously, I think this talk is geared more towards the U.S. audience, but most of the world has no access to CAR T, period, except for research protocols, and that makes things really tough. So, I think that’s one unmet need in general, where those patients who cannot get to CAR T never see me, and that’s a big disparity in the field.  

Two, I would say that the autologous CAR T products we have, autologous is the word that we use for the T cells that are coming from the patient themselves. Both ide-cel (Abecma) and cilta-cel (Carvykti), again, it’s the patient’s own cells that are being taken out, turned into CAR T cells, and put back. That manufacturing process takes time. Typically, I tell patients to expect about one to two months, closer to two months often, between the day that the T cells are taken out and the day they’re put back in again, what we often call the quote unquote “vein-to-vein interval.” And that’s hard because for some patients that’s not practical. 

The myeloma is, you know, so aggressive, behaving aggressively, that they cannot wait. There’s no drug I can give them where I can wait two months for the T cells to be manufactured. We’re getting better at it. The drug company is working better at it. There are a lot of investigational products that are not FDA approved yet that are looking at rapid manufacturing, where can you grow these T cells and the CAR T cells in two days or one day, instead of several weeks? I think that’s really interesting. 

There are studies of allogeneic CAR T cells, where the T cells are pre-manufactured from a healthy donor and manipulated so they won’t cause any other problems, but will attack the myeloma. So, a lot of research happening there, but that’s the problem for patients where they cannot get to CAR T therapy.  

And then the third unmet need would be – I’m seeing more of this, unfortunately, right? CAR T therapy is not considered curative for myeloma. Have I met people who are doing great years out from myeloma? Yes, from CAR T therapy, and I love that. In the original LEGEND-2 study, the study that led to the CARTITUDE-1 study that led to the approval of cilta-cel, which is Carvykti. 

If I recall correctly, about 20 percent of patients on that first Chinese study years ago are alive and disease-free five years later. That’s not enough, right? I don’t want it to be 20 percent, I want it to be 100 percent. And so we have work to be done there in terms of what do we do when the myeloma, the CAR T cells stop working, or they’re out of the system and are no longer there to fight back. What do we do next? And I think that’s another unmet need still.

Katherine Banwell:

We’ve been talking about CAR T-cell therapy for a number of years now. How has this treatment revolutionized care for patients? 

Dr. Rahul Banerjee:

Absolutely. So, the biggest benefit of CAR T therapy, I think, is how well it works. So, I’ll predominantly focus on multiple myeloma, but of course there are CAR T therapies that are approved for different kinds of lymphoma, and B-cell leukemia as well. But in brief, CAR T therapy, we train the immune system to fight back against the myeloma, against the cancer that’s there. And it’s phenomenal, because it’s the only living drug we have, really, in our toolbox. Everything else is dependent on the dose, right? As soon as the drug is out of your system, it stops working. CAR T cells don’t work that way. They can live and expand and proliferate to get rid of the threat within. 

And at least in myeloma, for example, CAR T therapies regularly have response rates, meaning complete response rates, how quickly they knock all the myeloma parameters down to zero basically in the 70, 80, 90 percent range. Many patients achieve measurable residual disease, or MRD negativity, meaning by all the best tools available in 2024, no sign of the myeloma anywhere.  

That doesn’t mean cure, to be fair, but that’s wonderful. With other conventional therapies, to have one drug with one infusion have that big of an impact on the myeloma is phenomenal.  

The other benefit of CAR T therapy is that it is a one-time infusion. It doesn’t mean that patients can get one-time CAR T and never have to see a cancer doctor again because again, at least in myeloma, I don’t consider CAR T to be uniformly curative for patients. However, if you look at the studies, and there’ve been two randomized studies in myeloma of CAR T therapy versus standard therapies. One was a KarMMa-3 trial with a drug called ide-cel, a CAR T drug also known as Abecma. And the other one was CARTITUDE-4, which was a study of cilta-cel versus standard treatment. And cilta-cel is a kind of CAR T also known as Carvykti.  

Both studies saw improvements, dramatic improvements in the response rate, how many patients had the myeloma numbers come down, but also durations of response and progression-free survival. How long patients were alive and disease-free for.  

Literally just a month ago, we found out officially that the cilta-cel trial and the CARTITUDE-4 study, CAR T actually prolonged overall survival compared to standard therapies, which is what patients are looking for.  

But for me, what I love about CAR T the most is not just that you’re in remission for longer, or with cilta-cel you live longer, but that you live better. Both studies, and I’m very happy to see this incorporated, what we call patient-reported outcomes, which is an area of research of mine. Patient-reported outcomes are, as you can imagine, outcomes that are reported by the patient. Not the blood test for the myeloma, but how are patients feeling in terms of their quality of life, in terms of their fatigue, in terms of their pain.  

And in both studies, off the charts. CAR T does way better and way faster in terms of improving quality of life than standard treatments, to the point where the studies, for example, often for both of them, if I recall correctly, the first time point where they looked and compared the two arms was three months after CAR T. And already by then, night and day difference.  

The patients who got CAR T, the first month a little bit rocky, but after the first month or two, they’re doing better, because they’re not on myeloma treatments continuously. They’re still getting blood work checked and so forth, but they’re not on treatment. It’s a one-time infusion and monitoring thereafter.  

And I love that about it, and I think that explains a lot of the quality of life benefits that we see.  

For my other patients with myeloma, outside of CAR T, there is never a scenario where they’re observed. The vast majority of patients because myeloma is considered incurable, we keep them on some form of maintenance treatment, and those come with side effects. Those come with financial toxicity. That’s the word we use for high out-of-pocket costs. They come with what I would call time toxicity. That’s time spent on the phone coordinating shipments or coming in for this infusion or that infusion. 

CAR T has much less of that, and I think that’s phenomenal. So, I would say that it’s revolutionized the field, not just scientifically from the things that you’d expect a researcher to care the most about – for how long, you know, how deep are their remissions and how durable are their remissions, but also for the things that I care about. The art of oncology is how our patients are living, and that’s why I think CAR T is revolutionary. 

Katherine Banwell:

Dr. Banerjee, would you walk us through the currently approved CAR T-cell therapies for myeloma and share how these treatments work to combat myeloma? 

Dr. Rahul Banerjee:

Absolutely so. So, there’s two FDA-approved CAR T therapies right now for multiple myeloma. One is ide-cel, also known as Abecma. One is cilta-cel, also known as Carvykti. The mechanics of them are pretty similar. Both involve T cells being collected from the patient and then turned into CAR T cells, cancer fighting cells in a lab, then put back into the patient after a small dose, what we call lympho-depleting chemotherapy, that creates a void and makes room for the T cells. 

And then the T cells come in and are able to activate and proliferate and respond and kill off the myeloma. In terms of the two drugs, the differences between them, we might come back to that a bit in terms of just how they’re approved. Cilta-cel is currently approved as early as first relapse. So, second line treatment onwards in myeloma for patients who have disease that is refractory to lenalidomide (Revlimid) or a similar class of drugs.  

So, lenalidomide is Revlimid. So, if someone’s been on Revlimid and it stopped working, they could technically go to cilta-cel, which is Carvykti, as soon as second line. 

Ide-cel or Abecma is approved for third line treatment, meaning at least two prior relapses or two types of therapy that were stopped unexpectedly because of not working or toxicities or so forth. And those patients would have had to have received both an iMiD, like Revlimid, which is lenalidomide, a proteasome inhibitor, which is like Velcade or bortezomib, and a CD38 directed monoclonal antibody like daratumumab, which is also called Darzalex or Darzalex Faspro.

How can patients find CAR T clinical trials that might be right for them? 

Donna Catamero:

So, ClinicalTrials.gov can point patients in the right direction. Again, the foundations – the Multiple Myeloma Research Foundation, the International Myeloma Foundation – can help direct patients toward clinical trials that might be right for them.  

Katherine Banwell:

How can patients start the conversation with their provider? What questions should they be asking about trials? 

Donna Catamero:

So, first, when you’re given options for treatment, you should always ask – always, always ask – “Am I eligible for a clinical trial?” 

All the therapies we have available today for patients initially came from clinical trials. In our early CAR T therapies, those patients had access to those drugs years before the general myeloma population, so clinical trials are key to really moving the therapies for tomorrow.  

Understanding Myeloma Therapy Targets BCMA and GPRC5D

What are myeloma targets, and how do they impact the effectiveness of therapy? Dr. Krina Patel explains how treatments like bispecific antibodies and CAR T-cell therapy are using myeloma targets such as BCMA (B-cell maturation antigen) and GPRC5D (G protein-coupled receptor 5D) to kill myeloma cells.

Katherine:

We know that the currently approved bispecific antibody therapies target BCMA and GPRC5D. What are these targets precisely and how do they impact the effectiveness of the treatment? 

Dr. Krina Patel:

No, it’s a great question.  

And, again, so BCMA we’ve had for a little bit longer.  

We’ve known about it for a little bit longer, B cell maturation antigen, which definitely we’ve used as much as we can. So, we’ve had CAR Ts for it. We’ve had bispecifics for it. We’ve had antibody drug conjugates that we’ve attached to it. 

So, it’s a really good target that is mostly just on myeloma cells and on very few other cells in the body, for the most part, which is why it makes such a great target. The side effects really should happen only specifically against the myeloma; so, less side effects in terms of toxicity. That’s not 100 percent the case.  

BCMA is in some other tissues, like maybe the nerves, and that’s why maybe we see this toxicity sometimes, potentially in the GI system. Some patients can have it in other places. If you have myeloma in, let’s say, areas like the kidney. If you have a plasmacytoma, it can go to the kidney, things like that.  

But again, for the most part, mostly on myeloma. And what’s really important about these targets is, once you get a treatment for it, what happens to that target. So, that’s a little bit different between these two targets. So, BCMA is a part of the proliferation of myeloma cells. So, it actually helps the myeloma cell survive. And so, the myeloma cells really want that BCMA on there. Now, for CAR T, for the most part, we don’t see people losing BCMA. We might see it go down in the myeloma cells that are left. For some patients, the expression can go down. But for the most part, we’ll see it come back up a few months later if the myeloma’s coming back.  

The way that resistance happens with BCMA is that, when people are on bispecifics, the other treatment, we can sometimes see the BCMA get mutated. And then, maybe the other therapies we have won’t go after it any more.  

So, again, it’s not common, but that’s sorta something we look at when we talk about sequencing therapy or which therapy should we use first. Then, GPRC5D’s a little different.  

So, again, mostly just on myeloma cells. But here, we do know it’s on something called epithelial cells, which is skin, nails, tongue. And that’s why some of the side effects that we see, especially with the bispecific that’s a standard of care already, talquetamab, is skin and nail changes. So, people can get sloughing of their hands and nails; that can get disrupted. And then, taste. People can actually have some significant taste loss, to the point that they can have weight loss from it.  

So, this is why that part is so important that if we have patients with these side effects, we need to hold the drug or decrease it; so, make sure we can turn those around. And then, the way GPRC5D is we think that it’s a little bit more likely that you can lose it once you get a treatment with GPRC5D that the myeloma can actually learn how to shed the antigen.  

So, again, this really becomes important when we talk about combination and sequencing of all these different therapies we have and what’s the best way to do it so that patients can have the best response and the longest response.

Katherine:

How can patients find and access clinical trials that are looking at CAR T-cell as an earlier line of therapy?  

Dr. Krina Patel:

That’s a great question. So, I think going to any place that is myeloma specific. So, basically a big center that has doctors that are doing myeloma research, they will be able to definitely get you into places that have some of these trials. But clinicaltrials.gov is one other place. It’s really hard. I will tell you that, if I wasn’t a physician or in medicine, I don’t think I would learn, I would be able to navigate it very well.  

And so, really either through your doctor and having them look this up for you, or going to patient groups. So, again, a lot of my patients are part of different patient groups where people will say, “Well, this is a trial that I was” or “This is a trial that my doctor told me about.” And then, asking. So, that’s the other big thing is constantly asking your doctor “What are my other options?” getting second opinions from myeloma experts, and then just paying attention to some of these resources that you have available. Right now, there are gonna be more clinical trials for earlier-line therapies and first-line with both cilta-cel and ide-cel 

There’s going to be clinical trials with new products: ddBCMA CAR T, that is likely gonna come out soon for earlier-line therapies. And so, there’s a lot happening, and so there might be different clinical trials in different places. But I think the fact that all this is going on at once is really important for our patients to know about.
