What are the risks of CAR T-cell therapy? 

Dr. Alsina:

So, in myeloma, it is, in general, pretty safe. There are two main – well, actually, I would say three main side effects that we can see with CAR-T. Number one is called cytokine release syndrome, and we are getting these cells from the patient’s immune systems, sending them a lab to be manufactured so that they can recognize this protein, BCMA, in the myeloma cells. 

And then, those cells are grown, so essentially, what we’re doing is that we’re taking the immune system of the patient, and we’re making it very specific against the myeloma cell. And then we’re growing it, so we’re making a hyperactive immune system, and then giving it back to the patient. And then, those cells, they are going to go ahead and react against the myeloma cells and start killing the myeloma cells, and in doing that, that reaction, that immune reaction will elicit release of a lot of proteins – cytokines – and that can cause side effects. 

When that happens, that is called cytokine release syndrome, and the most common finding with that is a fever. Patients can have a high fever. And then, it varies depending on the CAR-T that the patients are getting. So, for example, with this Abecma, usually, the reaction happens right away after you get the cells – the next day, so that’s why these patients, we admit them to the hospital because we know that this cytokine release syndrome is going to happen right away.  

And, it could be just a fever. In the majority of the patients, it happens like this, is just a fever, but it may be about 20 percent of the patients, that reaction can be more severe, and it could be a fever with low blood pressure or shortness of breath, and it could be a fatal complication, but that’s very, very rare.  

And we know – we can identify, obviously, when it’s happening, and there’s a medication that we can give to actually sort of counteract that reaction and don’t let it progress, and in the majority of the patients, that works quite well.  

Katherine:

What other side effects are there for CAR T-cell therapy? 

Dr. Alsina:

Yeah, so besides the main one that I discussed, cytokine release syndrome, the other thing that could happen is neurotoxicity, meaning that T cells can actually cross to the brain and cause toxicity in the brain, and depending on the type of CAR-T that the patient is getting, it could be less or more risk.  

But essentially, what could happen is that the patient could have some aphasia, like for example, difficulty finding words. It could also be just a headache. Patients could have seizures, so we do give the patients medication to prevent seizures while they are undergoing CAR-T. 

They can have difficulty writing, so we make every patient write a sentence every day to make sure that’s not being affected. And we do a mini mental status every day. Every day, we’ll go see the patient and ask them 10 different questions, like “Where are you? What day is it? Who’s the president?”, we show them an object, and so on so we can monitor these things very closely. If we see any changes, then we can intervene. Usually, for neurotoxicity, we give steroids. 

The good news, though, is that this is very rare. With Abecma, it’s very rare that a patient would have severe neurotoxicity. With ciltacabtagene autoleucel (Carvykti), which is the one that was approved more recently, from 100 patients that were treated, there were five patients that had this delayed neurotoxicity, some of them with movement disorders, like Parkinson’s-like systems, and these were delayed. These didn’t happen in the first few weeks. 

But we learned what are the risks associated with these, the majority of the patients that have very high tumor burden, so what we do is that we monitor the patients very closely, especially the patients with high tumor burden. The ideal situation is that we can control the disease a little bit better before taking them to CAR-T, but even when that’s not possible, what we do is that we intervene early on if we see that these patients are getting any side effects and being more aggressive with the intervention. 

And then, the third, more important side effect is these CAR-T cells can prevent blood counts to recover. For CAR-T, we give chemotherapy.  

That would allow the T cells to expand, and this chemotherapy can drop the blood counts, but usually, they recover quickly, but in some patients, this recovery doesn’t happen quickly, and patients can have low counts for months, and obviously, that would bring increased risk of infection. 

So, that is a potential complication, especially in patients that have received a lot of prior therapies, and it’s not common that a patient would take a long time, but it could happen, and sometimes, occasionally, we’ve had to give these patients a stem cell boost from stem cells that we have stored to actually make their counts recover. So, those are essentially the three most common complications, but in general, it’s a treatment that is well tolerated and very manageable, and I can tell you the majority of the patients that I’ve treated, they’ve said this is easier than a transplant.

 How Long Will Myeloma Maintenance Therapy Last?

Transcript:

Katherine:

I’d like to start by talking about innovations in myeloma therapy. How have treatment options for myeloma evolved over the past several years? 

Dr. Alsina:

Yeah, well, the easy answer to that is dramatically. It’s really amazing, the number of advances that we’ve had in the treatment. When I think 20 to 25 years ago, we had two drugs for myeloma, rare opportunity to get any patient in complete remission. 

And now, we have many, many drugs, we continue to have bone marrow transplants, now we have CAR-T cellular immunotherapies, and able to get patients – over 80 percent of the patients in remission up front, and even in the relapse setting, many of them with CAR-T, for example. One of the CAR-Ts is able to get 80 percent of the patients in remission, so it’s really incredible, the amount of advances. 

Katherine:

Yeah. How is CAR T-cell therapy changing the field? 

Dr. Alsina:

So, we – probably everyone knows that there have been two CAR-T products approved for myeloma in the past year. We’re not doing as good as the lymphoma group. Those were the first CAR-T cells, were approved for lymphoma/leukemia, and for those patients with lymphoma and leukemia, there’s an opportunity for a cure, whereas in myeloma, in the setting that we’re using CAR-T right now, which is for patients that have failed multiple lines of therapy, at least four prior lines of therapy, those patients are not cured.   

Katherine:

Yeah. You mentioned that there are two CAR T-cell therapies available right now for myeloma patients. What are they? 

Dr. Alsina:

So, the first one, that was approved in March of last year the commercial name is Abecma. This is made by a company that is called BMS. It targets BCMA, which is B-cell maturation antigen, which is the protein that is preferentially expressed in the myeloma cells, so it’s a really good target for myeloma, and this is the one that studies show that we get response rates at about 75 to 80 percent with remission rates about 40 percent, and in the real world, since Abecma was approved, we’ve treated many patients – at Moffitt, actually, I think we have the largest number in the whole United States, close to 60 patients, and we’re seeing the same.  

So, really, when we translate that to the real world, we’re seeing the same results, and I would argue that perhaps better because the patients that go on trial are very selective patients – they need to have good counts, they cannot have renal insufficiency, all this different criteria, and actually, when we looked at it, we found that 71 percent of the patients that we treated in the real world with Abecma would not have been eligible for trial, but yet, we’re getting the same results – the same results in terms of efficacy and the same results in terms of safety.  

Katherine:

What is the second CAR T-cell therapy available? 

Dr. Alsina:

The second CAR-T was approved just recently, in February of this year, and that is cilta-cel. The commercial name for this is Carvykti, and this one, we do not have a lot of real-world experience because the manufacture and availability of the product is still very limited, so we only have been able to do two patients per month with Carvykti. However, the studies show this agent to be extremely effective, with response rates close to 100 percent and a complete remission rate of 80 percent, which is… 

Katherine:

That’s phenomenal. 

Dr. Alsina:

Right? It’s phenomenal for this patient population. So, we’re definitely very excited with this. I think a major issue with CAR-T that you may or may not have heard – I’m pretty sure all the patients are aware of this, but it’s the availability. When these products are approved, because these products have to be manufactured from the patient cells, the companies cannot release – cannot meet the demand, so there are a lot more patients that need CAR-T than product availability.  

So, we have a waiting list, and this is true for all centers. With the first product, with ide-cel/Abecma, now, at least, in our center, we have been able to catch up a little bit. We’re getting about eight slots per month, so it’s a significant amount. We still are not able to offer it to every single patient that needs it at the moment, but we’re doing much better than the beginning. 

As I mentioned before, with Carvykti, it’s still a significant challenge, and again, we’re getting maybe one or two slots per month. Talking with these companies, they expect that is going to improve by early next year, so we’re keeping our fingers crossed because right now – and this is true for us and many myeloma centers – we have over 100 patients in the waiting list. 

But in any case, even with that, I would encourage any patient that needs CAR-T to go to a center because even though we have a long list, for example, some of those patients that are on the list, they don’t need CAR-T right now, so it doesn’t mean that 120 patients on the list need CAR-T at the moment. So, we normally would go down the list according to when we saw the patient, and then the needs of the patient at the moment that we have a slot, and that’s how we make our selection. 

So, the ideal situation is the patient seeks a CAR-T consult early on. Don’t wait until you have failed four therapies to go. When you start your third line of therapy, go, because then you get on the list. By the time you really need it and are eligible to get it, then it might be accessible to you.

Katherine:

When a patient is considering participating in a clinical trial, what sorts of questions should they ask their healthcare team? 

Dr. Alsina:

I think the number one thing is “How can this help me? What is the potential for this treatment?” The other very important thing is “What are the potential side effects? Has this been done before in other patients? Do you have any experience? What do you think are going to be the side effects or additional risk compared to getting the standard of care?” 

And then, I think the third thing is “How much commitment do you need from me?” Because there is no doubt that clinical trials require a lot of commitment. When we are doing a clinical trial, we, for example, have to give all the drugs in the center, usually. Let’s say I’m testing Revlimid (lenalidomide), Velcade (bortezomib), and dexamethasone (Decadron) followed by CAR-T, for example in patients with high-risk myeloma. That’s one of the studies. 

Yeah, you could get Revlimid, Velcade, and dexamethasone anywhere. Those are approved drugs. But if you are participating in a clinical trial, you have to get it at Moffitt or at the center, which means patients traveling back and forth, so that is very important because it requires a lot of commitment from the patients. And I think, on that line also, you can ask as a patient, “Well, what are the resources there in the clinical trial that can help me make that commitment?” 

Frequently, clinical trials help patients by paying for their transportation, their gas, their accommodations if they have to stay overnight, to be able to comply and meet all those different visits.

Katherine:

When it comes to myeloma treatment options, where do clinical trials fit in? 

Dr. Alsina:

They fit everywhere, essentially. They fit everywhere because myeloma – even though we have many, many advances, it’s a disease that we cannot cure, so there’s still a lot, a lot of work to do, so we have trials for newly diagnosed patients, improving what we do at newly diagnosed, bringing in some of those therapies, for example, like CAR-T up front, and then we have trials for early relapse/late relapse, because again, yeah, we’ve done a lot and we feel very encouraged by that, but we’re short because we have not been able to cure myeloma. 

So, it’s super important, and it’s super important that patients reach out to myeloma centers to see what is available for them because participating in a clinical trial, number one, gives a patient a unique opportunity to get something more than standard of care, something that might make their response better or their survival better.  

That’s one thing, and the other thing is the only way we’re able to move the field forward is doing clinical trials and having patients participating in clinical trials, and the reason today I can sit here and tell you that the treatment of myeloma has evolved dramatically in the last 20 years, and now we have these responses that are amazing that were unheard of, is thanks to the many patients that have participated in clinical trials. 

Without that, obviously, we would not be here with these results. But that needs to continue. I think we cannot rest because there are still patients that die from myeloma. We cannot lose the perspective that this is still an incurable disease and there’s still a lot of work to do, and the only way to get there is to continue doing the research. 

Katherine:

It sounds like clinical trials are also available for patients who have already been treated with another therapy. Is that right? 

Dr. Alsina:

Absolutely. Clinical trials are available for all the different stages of the disease – when you are newly diagnosed, when you have your first relapse, when you have your second relapse.  

Katherine:

Anytime through the process. 

Dr. Alsina:

Anytime, anytime, and there are clinical trials – the clinical trials not only help us test new drugs or new combinations of drugs, but it also helped us understand the disease better. The majority of clinical trials, we do what we call correlative studies, where we get a sample of the patient, the bone marrow of the patient, for example, before and after therapy, and we see what are the changes that we see there and what are the genes that dictate that response or lack of response. 

So, clinical trials not only help us improve outcomes in patients, but it also helps us understand the disease better that leads to other new therapies and other clinical advances. This can translate into new clinical advances.

Katherine:

What is MRD, and what does it mean for patients? 

Dr. Alsina:

So, MRD stands for minimal residual disease. So, it means that if a patient is in complete remission, what it would mean is that I don’t see any myeloma cells in the bone marrow and I don’t see an M spike. The M-spike is zero in the blood and in the urine, and the light chains are fine.  

But even with that, there maybe be some disease that is residual that I can’t see by conventional methods, so there’s two methods that have been developed that are able to detect one cancer cell in a million cells. 

Katherine:

Wow. 

Dr. Alsina:

So, if I have a patient that is in complete remission, I can use one of those methods to look, and that will tell me if the patient still has minimal residual disease or not. 

So, the reason why it is important is because there are many studies that have shown that if I can get a patient to be minimal-residual-disease-negative, no evidence of disease by those two tests – that I can explain a little bit more if you want – then those patients are going to do better, their response is going to last longer, and the patients are going to live longer. 

So, nowadays, with our better treatments, we use also that as a goal. We say okay, I not only want to get a patient in a complete remission, I want to get that patient to MRD negativity.  

And we do adjust our therapy to get there. As an example, I can do a transplant in a patient, and three months after transplant, I look at that minimal residual disease. If it’s negative, then I do Revlimid (lenalidomide) maintenance, which would be standard of care. If it’s positive, I use two drugs to try to get that patient to that MRD-negativity level, and there are many studies right now looking at how to adjust our treatment based on response.

Key Factors That Guide Myeloma Treatment Decisions

Transcript:

Katherine:

We know that patients undergo testing when diagnosed. How do test results affect treatment choices? 

Dr. Alsina:

So, in general, we do a bone marrow, we check for the genetics of the myeloma cells, see what are the genes that are affected in the myeloma cells, and that helps us define myeloma as high-risk or standard-risk, and that can help us decide what treatment we want to give these patients. Unfortunately, it’s not totally well defined. 

I wish we could use that in a better way and there are drugs that could really target, but there is some information. We know, for example, that proteasome inhibitors are important for patients with high-risk myeloma, so we definitely try to include that in a patient that is high-risk, and the other thing is that patients that are high-risk, it’s even more important to get to that remission, so we’re going to push treatment to get there, treat these patients a little bit more aggressively. 

Other than that, depending on, for example, what are the blood counts – some patients have a lot of bone marrow involvement and their blood counts are very low. This is not common, but it happens, and so, when that happens, we might be more aggressive up front and give these patients more aggressive chemotherapy to clean the bone marrow before changing them to the more normal therapies because the treatments that we give, like Revlimid (lenalidomide), Velcade (bortezomib), Darzalex (daratumumab) can depress the counts, right? 

So we’re in that battle. The patients already have low counts, we give the treatment, the treatment lowers the counts further, so it’s hard to give these treatments in these settings. And then, the third thing that we take into account is kidneys. About 25 percent of the patients will have renal insufficiency when they are diagnosed. Some of these drugs, particularly the immunomodulatory drugs like the Revlimid are metabolizing the kidneys, so it’s very hard to dose these drugs when the patients have renal insufficiency. 

So sometimes, for these patients, we avoid the IMiDs up front. We give a different combination until the disease gets better, and then we introduce the IMiDs. We think these immunomodulatory drugs like Revlimid are super important in the treatment of myeloma, so we want to give them, but sometimes we have to delay starting them until the patient’s kidney function improves.
