How can CAR T-cell therapy access be improved? Expert Dr. Krina Patel from The University of Texas MD Anderson Cancer Center explains strategies that have increased CAR T access, monitoring of CAR T patients, and advice for patients to access support.

[ACT]IVATION TIP

“…talk to your teams, if it’s not the doctor, at least the nurse practitioner or the nurses about resources, because through the pharmaceutical companies as well as things like LLS and other places, they actually have funds for people going through trials or CAR T therapies, etcetera, that we can help. My nurse knows all these things that she knows how to start working in our social worker and our case managers, they all know all these things so that they can get you the resources you need…”

Lisa Hatfield:

Dr. Patel, given the exacerbation of existing barriers during the COVID-19 pandemic, what strategies do you believe are most promising for enhancing patient access to CAR T therapy, particularly in terms of innovative clinical trial designs and stakeholder collaboration? And one of the questions that comes up a lot is during COVID I was able to participate in a clinical trial, but I could do some things closer to home where we don’t have a big center. Are those strategies still in play? So patients might be able to travel, maybe once a month or once every two months for a CAR T trial and then go home for a little while. Can you talk about that a little bit?

Dr. Krina Patel:

Yeah, I think COVID did help us learn how to use telehealth much more, where when it was allowed, I think the good news when we had it, we could do it for all 50 states. It was amazing. All my patients I could talk to through virtual visits, etcetera, use their local labs. Clinical trials are a little harder because you have to have labs that are certified and making sure that they’re able to do those intricate labs that you need.

For instance, certain things are central labs for where they have to look at your T cells and how they’re expanding over time while you’re getting CAR Ts. So we call those central labs because those are labs we draw and send to the company, to whatever lab they’re using to help with that stuff. Things like CBC, your blood counts, your kidneys, liver. Yes, those things are easy to get anywhere. There are multiple labs like Quest and Labcorp, etcetera, that can do those.

So I think those are things that we can help with. It’s the first 30 days of any CAR T study that for safety reasons right now, we still say you have to be at the center where you’re getting the CAR T on trial or even off a standard of care. And that’s more for if you get one of these toxicities like the delayed neurotox or an infection, that we can get you back into the hospital if needed or at least get you diagnosed really quickly and treated quickly.

But yes, after those 30 days, at least most of our CAR T studies really try to limit how often you have to come in. So once a month is pretty typical and then once every three months after the first couple of years, and then once a year if that. I hope that with the FDA and with our sponsors, our pharmaceutical companies that run these trials, that they can really help get these things, the logistics figured out, because that’s what it ends up being. Once you’re done with your first at least three months of CAR T, we know patients are going to do well. And it’s really about whatever labs and visits we need to do, how can we do them virtually? And again, if my sponsors and the FDA would allow that, we’d be really happy to.

And I know the FDA is all for it. They are trying to help increase access as well. And so some of the bigger centers like us, and I think Sloan Kettering and City of Hope and Mayo, we also have other centers that are outside of the main campus. So MD Anderson doesn’t have other hospitals the way Mayo does. So Mayo has Arizona, has Rochester, and Florida. MD Anderson has a sister network.

And so we’re hoping to tap into that one day, because there are places everywhere. And if we can do that, that would actually help get access to a lot of these novel therapies a lot faster to our patients. And within Houston, just being such a big city, we have four other centers out in the outskirts and we are trying to actually increase our abilities to do therapies there as well, including CAR T and bispecific therapies.

Lisa Hatfield:

Thank you for that, Dr. Patel. So one question, I have a follow-up question. If a patient has to travel, maybe they live in an area where there is no academic center, they’d have to travel for a clinical trial. And you mentioned the first 30 days. Are patients usually, one of the big challenges is financial, is a financial challenge. Are patients sometimes feeling well enough during that 30 days if they can work remotely? Can they work remotely while they’re at your institution for 30 days? Is that pretty typical or is that something you don’t see very often?

Dr. Krina Patel:

Yeah, no, that’s a great question. So we are trying to make the whole thing outpatient soon, and a lot of our trials are allowing for CAR T outpatient, and only if you get a fever, then we admit, most people do get admitted because most people get fevers from the CAR T, but for the most part patients still feel well, it’s not that they’re having this horrible nausea, vomiting, diarrhea, things that we think about with auto transplant, where people really can’t work because they’re just exhausted. The majority of our patients are bored in the hospital, it really is that we’re just there just in case the fever turns into something worse. So a lot of my patients who are still working actually do work remotely, I can think of a few just this past week that talked about the fact that they were able to do this.

And I think the other piece we have so many resources. And again, the big activation tip here is talk to your teams, if it’s not the doctor, at least the nurse practitioner or the nurses about resources, because through the pharmaceutical companies as well as things like LLS and other places, they actually have funds for people going through trials or CAR T therapies, etcetera, that we can help.

My nurse knows all these things that she knows how to start working and our social worker and our case managers, they all know all these things so that they can get you the resources you need and some of the centers, our academic centers have resources as well. We have housing for free, you have to sign up for it in advance, but you might be able to get housing for free for that whole 30 days, and so there’s a lot of different resources that you just have to ask about, and then again, through our social worker, case manager, nurses, and sponsors. We can actually get some of that for you too.

Lisa Hatfield:

There have been some discussions about post-CAR T, particularly with T-cell malignancies and monitoring for that. Can you just give a little description of that and any concerns that you have with that or any encouragement you have regarding that and whether that weighs into your treatment options that you give to patients when they are asking about CAR T therapy?

Dr. Sikander Ailawadhi:

Absolutely. Extremely important question, Lisa. This really had a lot of discussion going on. It’s been going on for the past few months now. Okay. So first let’s explain the landscape. The FDA reviewed CAR T-cell treatment because of the fact that there were about 19 T-cell malignancies noted in several thousand patients.

Out of those 19 cases of T-cell malignancies, there was one case of multiple myeloma to the best of my knowledge. Now, risk of subsequent cancers is something, unfortunately, every cancer patient lives with, but in myeloma, we have known about that, especially from our historical knowledge of second malignancies with lenalidomide-based (Revlimid) maintenance therapy post-transplant. So subsequent malignancies have always been a risk.

There is some risk that is being talked about with CAR T, but frankly speaking, the way I look at it, the risk is significantly lesser than the potential benefit. Because remember when these CAR T therapies, the two agents got approved in myeloma, they were approved in a situation that there was no standard therapy. And we saw somewhere about 70, 75 percent response rate with one of them and about 98 percent response rate with the other one. So in a setting where there was nothing, you can see the degree of benefit. And the risk of second malignancies is relatively small. So we must discuss this.

A patient must be aware of it, but I think the benefit is way more than the risk. So we document, we discuss, we have specific documentation that we do and specific information that we share with patients, but I think still the benefit is significantly more than the risk.

Lisa Hatfield:

We are going to jump right into a discussion about some of the novel therapies that there is much buzz about right now, and it’s kind of an alphabet soup these novel therapies. I actually was trying to digest all of this information and divide it into the general categories.

And correct me if I’m wrong, but we have monoclonal antibodies, we have bispecific antibodies like the CAR-T therapies, and they target different things. We have BCMA, we have GPRC5D, FcRH5, we have things called antibody drug conjugates and cell mods. So, Dr. Ailawadhi, if you can just give us kind of a broad overview of these therapies and how they may be used to harness our immune system, and how they come into play when you’re treating your patients, how and when they come into play when treating your patients.

Dr. Sikander Ailawadhi:

Surely, so I think thanks a lot for bringing up that discussion, this is extremely important, and I think it’s most important because if a myeloma patient goes online and wants to search for information or research, these things start coming up this term start coming up. So it’s extremely important for a knowledgeable and empowered patient to learn about these, understand them, so that they are able to digest that information. And I should mention that a lot of what we’ll talk about about these particular treatments may not be applicable to newly diagnosed patients or a recently diagnosed patient, but this is important enough and exciting enough that I would want every single patient to pick up this information. Learn it hopefully, and maybe park it for now somewhere, so that hopefully down the road it becomes important and handy.

So you asked about monoclonals, bispecific, CAR-Ts, cell mols, etcetera. Let’s take a step back, let’s think about these as strategies to target myeloma. Myeloma treatment is going through a change where immunotherapy and harnessing the body’s own immune system is becoming extremely important, and when we do that, the immunotherapy is typically very targeted, so what these drugs these agents, these terms, this alphabet soup is doing is it is targeting specific markers on the myeloma cell on the plasma cell.

For example, one of the markers is CD38. There is a monoclonal antibody. There are actually two monoclonal antibodies. Daratumumab (Darzalex), rituximab (Rituxan) that are FDA-approved, but there are other ways of targeting CD38, for example, CD38 targeting CAR-T cells, CD38 targeting antibody drug conjugates, etcetera. So CD38 is one important part. A very, very, very important thing in the past one year or a year-and-a-half has been what’s called B-C-M-A, B cell maturation antigen. BCMA is another target on plasma cells. Very effective, very specific.

So there are many, many drugs that are available and becoming available to target BCMA. Right now, there are three drugs that are FDA-approved that can target BCMA. Two of them are CAR-T cells, a particular way of going after BCMA in which the body’s own T cells are collected. These are not stem cells, these are T cells, T lymphocytes, these T cells are collected, they are actually genetically modified to go and fight against the BCMA, and then those modified T cells are multiplied in the lab and given to the person as a drug, they go and seek the plasma cells because of BCMA kill them harnessing the body’s immune system.

So there are two CAR-T cells against BCMA, one called ide-cel (Abecma) and one called cilta-cel (Avekti). There has recently been available a bispecific antibody against BCMA, we call it bispecific because it connects to BCMA from one end and from a second it connects to the body’s T cells again, bring the T cells close to the plasma cells to kill them. Then bispecific antibodies called teclistamab (Tecvayli). And until recently there was another drug available against BCMA which was what’s called an antibody drug conjugate. This drug is called belantamab (Blenrep) for the timing, belantamab has been removed or withdrawn from the market in the U.S., but there are ongoing clinical trials and down the road, it may come back again.

Now, antibody drug conjugate is another way of targeting something in which there is a seeker for the BCMA in this case, and it has a payload of some kind of a toxin, so that when the drug connects to the plasma cell through the BCMA in this case, that toxin is released, it can kill the cell, so either we harness the body’s immune cells, the T cells by CAR-T or bispecific, or we kill the cell by releasing a toxic payload from a drug, antibody drug conjugate, these are all different methods of targeting the myeloma cell. So I talked to you about monoclonal bispecific CAR-T and ADC as different strategies, CD38 and BCMA, some of these strategies are available, but there are other targets which are very exciting and new drugs are being developed against them, two of the very interesting targets there one is called GPRC5D, and the other is FcRH5.

These GPR5CD or FcRH5 are two different targets on myeloma cells. No drugs are currently FDA-approved, but they are being developed very rapidly, and we have a couple of extremely promising agents which will be coming down the pipe. And you also mentioned something called cell mods. Cell mods are some newer drugs in the family of what’s called IMiDs or immunomodulators, in which our patients may be aware of thalidomide (Thalomid), lenalidomide (Revlimid), and pomalidomide (Pomalyst). The cell mods are kind of the same family, and there are a couple of them that are also being developed.

So why is this important for everybody, whether they are newly diagnosed or relapsed or long-term survivor with myeloma, because this tells you that not only are we getting newer drugs in the same classes, we are also getting brand new classes of drugs, and you can imagine that means that those brand new strategies are ways to target the plasma cell, we know cancer cells are smart and they develop invasive mechanisms to become resistant to drugs, but every time something gets resistant if we have a brand new mechanism to go against the disease, but that’s exciting because that’s why we are seeing deeper responses, even in very heavily pre-treated patients, because we are using newer specific, relatively safe, convenient strategies to going after the plasma cell.

I know that was a lot of information, but I hope this helps our listeners learn a little bit about what you rightly said is an alphabet soup, but I would like us to think about it as an exciting time for being a myeloma doctor, and certainly a very hopeful situation for all our patients.
