Lisa Hatifield:

Hello and welcome. My name is Lisa Hatfield, your host for this Patient Empowerment Network START HERE program, where we bridge the expert and patient voice to enable you and me to feel comfortable asking questions of our healthcare teams. The world is complicated, but understanding your multiple myeloma doesn’t have to be. The goal is to create actionable pathways for getting the most out of myeloma treatment and survivorship.

Joining me today is Dr. Ailawadhi, back by popular demand. Dr. Ailawadhi is a respected multiple myeloma expert from Mayo Clinic. Dr. Ailawadhi’s career focus includes the treatment of plasma cell disorders like myeloma and understanding the epidemiology and pathophysiology of this disorder. It’s always such a pleasure having you, Dr. Ailawadhi. I’m really excited you’re joining us again. So thank you for joining us.

Dr. Sikander Ailawadhi:

And thanks a lot for having me, Lisa. This is excellent. I look forward to this next iteration of the Patient Empowerment Network START HERE program.

Lisa Hatfield:

Thank you. So before we dive into today’s discussion, please take a moment to download the program resource guide using the QR code. This guide contains pertinent information to guide you both before and after the program. And this program will provide you with a comprehensive update on the latest myeloma news and its implications for you and your family. Following that, we’ll launch into some questions that we have received from you.

So let’s start here. Dr. Ailawadhi, at this juncture in myeloma history, we are witnessing unprecedented activity, a surge of new treatment options, and a wealth of insights. Today, we are privileged to have your expertise to help us decipher these developments and shed light on the advancements shaping the landscape of myeloma care. First, we’re going to get a high-level update from Dr. Ailawadhi on what the latest myeloma news means for you and your family. And then we’re going to talk about some questions that you’ve sent in. So let’s get started with the high-level update, Dr. Ailawadhi. Can you speak to the latest news and priorities in the rapidly expanding myeloma treatment landscape?

Dr. Sikander Ailawadhi:

Excellent. I think, Lisa, that’s an excellent and important question. Because as you rightly mentioned, there is such a large amount of data that is coming through for myeloma all the time. I mean, it’s almost, we kind of talk about the fact that every time you turn your shoulder or look over your shoulder, there is a new drug approved. So I can imagine this can be very overwhelming. So what I’ll say is that in my opinion, there are some categories of new data that are pertinent and important for our patients. 

The two or three out of them that come to my mind, one is what’s called CELMoDs, or there are a couple of agents there called iberdomide, mezigdomide. These are showing some interesting data. Important to keep in mind that they are somewhat related to the immunomodulatory drugs lenalidomide (Revlimid), pomalidomide (Pomalyst), but they’re showing benefit in patients who have had len and pom before and have progressed. So exciting stuff there.

We’re also seeing some interesting data about newer CAR Ts and bispecific antibodies. They are all coming up with some benefits in some cases. I think it’s important to keep in mind that the bispecifics are landing at the 60 to 70 percent response rate, and CAR Ts are typically landing at the 80 to 90 percent response rate, but there are more agents expected.

There are also some newer bispecifics in different classes, like one of them is called cevostamab, which is an FcRH5 inhibitor or targeting bispecific. So newer bispecific, not just more of the same category. And there has also been recent data about Bcl-2 inhibitors, which have been traditionally used for patients with translocation 11;14.

There have been some negative data, negative as in trials, which did not pan out with a drug called venetoclax (Venclexta), but there are two other drugs that had some recent data shown from different companies, which were exciting information. So in my mind, those are kind of the broad new drug categories. There is another, a couple of other quick things that I’ll mention.

One is we’re getting more and more information about real world experience with these new drugs. It’s good to see that CAR Ts are panning out very similar in the real world as they are in clinical trials. We’re also seeing that the side effect profile of a lot of these newer novel immunotherapy drugs is similar as seen in the clinical trials.

Racial ethnic disparities are something which are very close to my heart, and there is more and more information coming out in that. Unfortunately, highlighting the disparities more still rather than yet coming up with solutions. And I think the last thing that I feel which has been recent has been at the American Society of Hematology meeting in 2023, which was in December in San Diego.

One of the myeloma studies actually became a plenary session presentation, which is a pretty big deal for any disease area. So one thing is that it gets highlighted. Secondly, it was a combination of a regimen called isatuximab-irfc (Sarclisa) with carfilzomib (Kyprolis), lenalidomide, and dexamethasone (Decadron) in newly diagnosed patients.

It’s a randomized trial, Phase III, which was presented. I think the important part is we saw unprecedented deep responses and patients in much, much higher numbers than before becoming MRD-negative. So very deep responses. So these are kind of some very broad, but lots of highlights that I talked about.

Lisa Hatfield:  

All right. Thank you. So can you also talk about some of the newer tools for myeloma progression and relapse and what patients might want to know about that? And in particular, maybe talk a bit about MRD testing and the role of MRD testing for patients who relapse.

Dr. Sikander Ailawadhi:

Excellent question. Lisa, I think the first and foremost thing an important part for our patients to learn is what are their “tumor markers,” for the, or disease markers for myeloma. We can follow myeloma by either the M spike or monoclonal protein, by light chains, by monoclonal protein in the urine or blood. And it’s important to keep that in mind because every now and then we’ll see patients who say, Hey, my ratio changed. So I’m progressing. Well, that comes after the light chains change. So it’s important to understand the role of these things.

So M spike in the urine, M spike in the serum and light chains. One of them is typically the marker for a patient. Now the MRD status or minimal residual disease that is looking for one cell, one myeloma cell from amongst 100,000 cells in the bone marrow. So it is looking at a very deep level. The most important benefit of MRD testing right now is to understand that if a patient turns MRD negative, then they have a superior outcome. Their prognosis is better. Their progression free survival, or the time before their disease comes back is longer. 

But when a patient is MRD-negative and is being followed or maintenance or whatever, if the bone marrow turns MRD-positive, then that might be the sign that the disease might be coming back. Right now, we do not keep switching drugs to get to MRD-negative. That is not the goal of treatment. The way to think about it is we want to get to MRD-negative, but that means it’s incumbent upon us to try and pick a regimen that is more likely to get to MRD-negative. That’s the way to think about it.

Let’s pick a regimen more likely to get us into MRD-negative and hope that we get to MRD-negative. We see every now and then that the patients keep switching regimens just to get to MRD-negative. That’s not the way to go because you’re just using up options too quickly, too fast. A common question that patients ask is, well, does that mean I need to get annual bone marrow biopsies and MRD testing? Probably not.

That’s too much testing. So what I suggest is that once somebody has turned MRD-negative, it’s important to keep an eye on every single thing. Now, change in any of the routine labs, imaging, new symptoms, etcetera. That’s when we switch to the bone marrow again and see if the patient has turned MRD-positive. There are clinical trials going on right now which are stopping drugs based on repeat MRD negativity or starting drugs on MRD positivity. But those are clinical trial questions.

Lisa Hatfield:

Okay. Thank you for that. So along those same lines, since you’re a Mayo physician, I’m curious about the mass spec testing. So if a patient say has been MRD-negative for some time, still wants to monitor at a deeper level, even though it’s not commercialized yet, do you see a role for mass spec testing on a regular basis in the future and being rolled out to community facilities also?

Dr. Sikander Ailawadhi:

Absolutely, Lisa. I did not specifically bring it up because mass spec is not, like you rightly said, is not yet commercially available. Now we’re doing mass spec quite frequently at Mayo Clinic. Basically mass spec is taking up a blood sample. Important to keep in mind, it’s not a bone marrow test, it’s a blood test, but it looks for those abnormal proteins based on the protein weight at a much, much lower level. Our SPEP or serum protein electrophoresis does not pick up very small quantities of the protein mass spec does. So in an essence, the mass spec, if somebody is negative on that, turning mass spec negative to mass spec positive may be an earlier sign of the disease coming back rather than the SPEP yet turning positive. But as you rightly said, it is not yet commercially available. I do see the benefit of it.

There is more and more data coming in favor of it, and there was data that was also at ASH. So I do see that in the future we’ll be able to most likely have it available more widely. At this point, it is just a blood test to attempt to check the disease level at a much deeper level and be able to notice if the disease is progressing sooner than our currently available tools.

Lisa Hatfield:

Great. Thank you. And as a patient, I like to have one more data point that they can get from my blood, not from my bone marrow to assess the disease. So thank you for explaining that. Regarding survivorship, patients are living longer with myeloma in general because of the novel therapies that have come out in the past few years. So how is myeloma survivorship evolving, and what’s different now than it was five or 10 years ago in terms of treatment planning?

Dr. Sikander Ailawadhi:

Yeah, I think it’s very important to keep that in mind. When I see a newly diagnosed patient, I’m not just telling them, “Hey, this is your induction therapy, and your transplant is the goal.’ We’re trying our best to decide that patient’s life journey with myeloma over the next 10, 15 and hopefully more years. So we’re trying to pick and choose the regimen that is most likely going to help the patient the most today and most likely will give a longer duration of the response. So when you say survivorship, that also very importantly brings up the point that patients are living with myeloma longer. We have to manage their health overall. So looking for any side effects from treatment, managing them very well so the patient is able to stay on the treatment and maintain good quality of life.

There are actually, are clinical trials looking at stopping treatment when there is a very deep, prolonged response. Again, going towards survivorship and giving the patient’s quality of life. There is looking for other cancers. In fact, I had a patient in the clinic and we were talking about just myeloma in general and I was telling them, “Okay, please remember you may not want to do a colonoscopy, but you already have one myeloma cancer diagnosis. The risk of subsequent cancers is always there in any cancer patient.” So that was a male person. So I said, “Okay, please do not miss your colonoscopy. Please do not miss your prostate screening and whatever is age-appropriate must be done.” So managing everything because myeloma is not a sprint, it’s a marathon.

We want to make sure that we pace ourselves well so we manage all the symptoms, all the signs. Bone health becomes much, much more important because the same bone structure is now going to carry us longer and many more years. And as you rightly said, planning, which treatment comes first, which comes next, when does CAR T come? It’s not that everybody must get CAR T today. That’s not the answer. So what to use when becomes extremely more important.

Lisa Hatfield:

Thank you for that. And thank you, Dr. Ailawadhi, for that important reminder. All of you watching, get your regular screenings, like he said, prostate cancer, mammograms, colonoscopies, get it done. So thank you for that.

One of the things that comes up with that regular, not regular screening, but monitoring after certain therapies for future malignancies, there’s 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 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:

Great. Thank you so much for explaining that. And for any of you out there watching this, Dr. Ailawadhi is a myeloma specialist, and I highly encourage anybody who is looking at CAR T therapy or even for a first consult for myeloma, seek out even one consult from a myeloma specialist. It is so important in trying to understand these therapies and any fears you may have regarding those therapies and the risks of that. So really appreciate that, Dr. Ailawadhi. Thank you. So I think it’s time now to start answering questions from patients that we received from all of you in the audience.

Please remember, this is not a substitute for medical care. Always consult with your medical team. And we are going to jump right in, Dr. Ailawadhi. We have a lot of questions from patients here and I’ll just start with the first one. This patient is asking, my M spike keeps rising in spite of chemo. What can I do?

Dr. Sikander Ailawadhi:

Very important question, Lisa. Every patient must understand what their disease marker is. This patient is asking about the M spike, which is the monoclonal spike, whether it’s in the blood or in the urine. And if the M spike is continuing to increase and there is a significant increase, significant is defined by at least 25 percent from the nadir or from the bottom most point with the, at least a absolute increase of 0.5 gram per deciliter. So half a gram per deciliter. So we want a 25 percent increase, but we also want at least 0.5 gram per deciliter.

So if somebody had an M spike of one at their best point, then the increase to 1.5 is significant. If somebody had the M spike of 0.2, then it’s not the 25 percent increase, it’s the 0.5 that must happen. So they hit 0.7 and that’s a significant increase. So that’s how we think about M spike, 25 percent with an absolute of at least 0.5 gram per deciliter.

If that is indeed happening, this would be considered a biochemical progression. And at that point, it should be considered to switch around the treatment because we don’t want the disease to grow to the point that there are actually symptoms showing up or organ damage happening. We want to be able to capture the disease progression sooner and act upon it.

Lisa Hatfield:

Great, thank you. Do you have any recommendations for people who, as we might have some patients watching this, who are light chain only? Any guidelines on if those numbers are rising?

Dr. Sikander Ailawadhi:

That’s an excellent question too. So if somebody has light chains as their marker, we are looking at an increase in the involved serum free light chain. So if somebody has kappa as their marker, the kappa is going up, or if they have lambda as the marker, the lambda is going up. Typically, if both of them go up, that is not disease progression. That could be coming from kidney dysfunction. Somebody is dehydrated and they get labs checked. Both kappa and lambda might be elevated. Again, a 25 percent increase in the absolute. But at the same time, we are also looking at at least 10 milligram per deciliter change.

So if somebody had a light chain of two milligram per deciliter, if it goes to 12, that might be a significant change. But I can say that light chains are a little bit more volatile and they do get affected by our fluid status. So if I ever notice a patient with a light chain increase, I’m more likely to repeat the test very soon, maybe even at a couple of days, one week interval, just to make sure that there is a trend rather than just a fluctuating light chain.

Lisa Hatfield:

Okay. Thank you for that information.

Dr. Sikander Ailawadhi:

And I should maybe, very quickly add, we do not check light chains in the urine. Light chains should be checked in the blood. Urine light chains are very nonspecific and there’s no need to test them.

Lisa Hatfield:

Okay. That’s helpful also. So patients don’t have to walk around with their big orange jugs full of fluids. So thank you. All right. This might be a complicated question to answer. But in general terms, for those who relapse for the first time, what are the best treatment options?

Dr. Sikander Ailawadhi:

I think that’s a very important, and I can imagine a scary situation. So somebody who relapses in general, not just even the first time, the factors that are taken into account for deciding what treatment they should get, there are broadly three categories of factors. Patient factors deciding what’s the age, what’s the other comorbidities, are they diabetic, are they heart disease, kidney dysfunction, because those things go into the decision of what may or may not be given. So patient factors.

Also importantly, how close are you to your treatment center? Can you come in for infusion or injection drugs time? And again, can you prefer or do you prefer oral drugs only? Et cetera. Those things become important. Then that…so that’s patient factors and disease factors. How fast is the progression? Is it high-risk disease, standard risk disease? Is it biochemical progression like the previous person asked?

Or is it actually a clinical progression in which there’s kidney dysfunction or anemia or bone disease? Because the choices and the urgency of treatment may change. So patient factors, disease factors, and then drug factors are the third class or third category, which is what have you had before? How long have you been on it? Are you on maintenance or not? Is your disease considered refractory to a certain agent, meaning resistant to a certain agent? Typically, if you were on a treatment and your disease is progressing, that same drug may not be used again.

And there are some times that we will reuse a drug, but generally not. We can use the same class, but we may not typically use the same drug. So I think the choice of treatment depends on all of those factors put in. And then we come up with one or two or three regimens and we discuss them with patients. And, of course, being an academic, physician, I must say there is always, you must always seek out good clinical trials if they’re available to you. That is the way our field moves forward.

Lisa Hatfield:

Yes, thank you for that information. So we have another patient asking, “Do myeloma patients require multiple prior therapies prior to being eligible for CAR T?” And what’s the rationale for not implementing CAR T immediately, which probably has to do with FDA approval based on clinical trials at this point?

Dr. Sikander Ailawadhi:

Absolutely. You’re absolutely right, Lisa. So any drug, let alone CAR T, any drug can only be given in the situation that it is approved by the FDA. So basically in accordance with that drug’s FDA approval label. Currently, CAR T-cell therapy is approved in the U.S. after at least four prior lines of therapy. And the patient must have had treatment with at least one proteasome inhibitor,  for which we have three drugs, bortezomib (Velcade), ixazomib (Ninlaro), and carfilzomib. They must have been treated with at least one prior immunomodulatory drug; lenalidomide, thalidomide (Thalomid), pomalidomide. And they must have been previously treated by at least one monoclonal antibody, daratumumab (Darzalex) or Isatuximab (Sarclisa).

Once the patient has had all these criteria met, they’ve become a candidate for CAR T-cell therapy. Frankly, we cannot just use a drug anywhere because we cannot use a drug where it has not shown to be of benefit. And importantly, it has not shown to be of any risk. So CAR T-cell therapy in the first line setting is being studied in clinical trials, but is not FDA-approved. Currently approved only after four prior lines, but the FDA is reviewing data for both the CAR T’s to see if they may be available sooner. As of right now, that approval is still pending.

Lisa Hatfield:

Okay, thank you. We’re hopeful that that will happen soon.

Dr. Sikander Ailawadhi:

Hopeful.

Lisa Hatfield:

Yeah. So interesting question from a patient, “Does CAR-T therapy actually change one’s DNA?”

Dr. Sikander Ailawadhi:

No. The CAR T therapy does not change one’s DNA. What happens is, there are T cells taken out of a patient. The DNA of those T cells is modified and then those T cells are given back to the patient. Those T cells do not go and integrate into your other healthy body cells or your stem cells, et cetera. Those T cells, it’s almost like giving a boost of immunity, which is targeted against your myeloma. So those T cells go in and they fill those myeloma cells. Now we hope that those T cells perpetuate and teach or create some memory T cells and that immunity lasts a little bit longer. But all of that genetic modification stays within the T cells. It does not integrate anywhere else.

Now, I know there was a previous question about T-cell lymphomas, that is related to this question in a way because the risk that is theoretical is, that that genetic modification in the T cells might make those T cells replicate uncontrollably leading to a T-cell cancer or T-cell lymphoma. But I’m saying that this is theoretical because while it is possible, it happens extremely rarely and even in the cases where the cancer happened, it has been seen that the cancer may not come from that portion of the DNA that was…that’s where the modification was done. So, low risk.

Lisa Hatfield:

Okay. Thank you very much for that.

Lisa Hatfield:

Okay. So what would be the next steps, Dr. Ailawadhi for a patient who’s had CAR T and reaches a relapse state or is relapsed?

Dr. Sikander Ailawadhi:

Yep. This is something, unfortunately is the truth of the matter in myeloma at least that we are, we don’t seek cures. We have had some long remissions. I have, for example, patients who are now reaching three, three-and-a-half years of remission on CAR T treatment who received it on clinical trials even before they got FDA-approved.

But, unfortunately, the disease does come back. So what happens is, we are seeing data that the novel, other novel immunotherapies like bispecific antibodies, even the ones who go after the same target as CAR T, BCMA targeting bispecifics, they do have some response rates, good response rates in post CAR T setting. So the bispecific antibodies by themselves may give us 60 to 65 percent response, but in the post CAR T setting, that response might go down to 40, 45 percent. So less responses, but still possible.

There are also bispecific antibody. There is one available, which is not against BCMA, it is against GPRC5D. That’s a bispecific called talquetamab-tgvs (Talvey). So a novel target. There is…there are of course a lot of clinical trials. There are some clinical trials that are even looking at CAR T post-CAR T. So different kind of a CAR T. Those clinical trials are going out. So what I would suggest is that if your disease progresses after CAR T-cell treatment, you should very strongly consider getting to a specialist myeloma center and get an opinion like you mentioned, Lisa.

That is so important because the choice of treatment is extremely important at that time. And we are trying our best to sequence all the options we have, in a way, actually one of my patients mentioned, one of these days, Hey, does that mean that I’m basically buying time till something new and exciting comes along? And I said in a way that is true. That we are trying to stretch all our treatments and get to the point that something new and promising just like CAR T comes, and hopefully we get longer benefits again.

Lisa Hatfield:

Thank you for that. So when you say there’s a possibility of CAR T and then a post-CAR T maybe a second CAR T. Would that be a different target then?

Dr. Sikander Ailawadhi:

So there could be a different target. I have, in fact, just yesterday I saw a patient who had received one CAR T in a clinical trial and then they were subsequently able to receive a CAR T standard of care, which had been FDA approved. So they used different CAR Ts, but one was in clinical trials and one was standard of care.

Lisa Hatfield:

Oh, great. Okay. Again, important to see a myeloma specialist to tease out all this information. Thank you. All right. This patient is asking, “I’m 81 and living with comorbidities. The myeloma was diagnosed after bone marrow test. How is treatment fitness determined?” And also a question about that is if you’re given an ECOG status of something you don’t like it, can that be improved after you’ve had treatment?

Dr. Sikander Ailawadhi:

Absolutely.

Lisa Hatfield:

Maybe be eligible for a trial or something.

Dr. Sikander Ailawadhi:

Correct. Correct. That is so important. When this patient mentioned that they’re 81-year-old and they’re living with comorbidities, I think, so when I’m talking to a patient who’s new to me, it’s very important for me to try to tease out what was their performance status or their fitness status prior to myeloma. Because my goal is to try to get them as close to that as possible. Now if this patient is saying that they were already quite frail before the diagnosis of myeloma and myeloma is added to the frailty, then it becomes a little tricky because we’re starting in a difficult spot. We do determine fitness by asking questions, simple questions like, what can a patient do at baseline? Can they do grocery store or grocery shopping by themselves? Can they walk around the block? Do they get short of breath? Et cetera.

And frankly, there are 81-year-olds who are playing golf every day and are fitter than me. So I’m just saying that age by itself is not the criteria. And, Lisa, like you rightly mentioned, if there are fitness issues coming from the disease itself, then that’s the time that we actually have to work with the treatment, get the treatment started, and then assess the fitness a couple of months later, a couple of cycles later. Because the treatment may have worked and may have improved the fitness quite a bit.

Lisa Hatfield:

Great thank you for that. So this person is asking, their husband is starting maintenance therapy, so I am assuming they just finished induction therapy, having leg pains mostly at night. Could this be a form of peripheral neuropathy or is maybe from bisphosphonates or from any of the medications that maybe were used during induction?

Dr. Sikander Ailawadhi:

So, excellent question. So, this is almost going back to that survivorship question that we discussed earlier, that it’s so important to manage the side effects and maintain quality of life. So, a lot of patients with myeloma will say that I have cramping or symptoms or some pins and needles at night more so. Part of it is because body’s at rest, relaxed, things, symptoms become more focused. Yes, it could be peripheral neuropathy, but at the same time certain drugs caused muscle cramping or what’s called myalgias, sometimes maintenance therapies can cause that.

It’s important for somebody to be able to determine is it coming from muscles or nerves? Is it coming because some electrolytes are abnormal. Like one of the common things is low magnesium or low potassium can cause neuropathy, for example, or cramping. I’ve had patients who will get some over-the-counter lotions or some forms et cetera, which are infused with some electrolytes and say that they feel some benefit. So topical things are good. So I think it’s important to figure out is it muscle or nerve and is it coming from drugs or disease? And that’s where your physician can help tease it out.

Lisa Hatfield:

Okay, thank you. So we have a patient who is talking about her genetic abnormalities, but has been through both auto and allo stem cell transplant in the last two years and has relapsed. And is asking, “Can CAR T-cell therapy help me?” And would she even be eligible for CAR T therapy given the allotransplant?

Dr. Sikander Ailawadhi:

That’s an important question. So first of all, sorry to hear that, that your disease is behaving that aggressively, that you’ve had both the transplants in the past two years and still having issues. So yes, CAR T can still be used after an allotransplant. There are some criteria. You should not be on any graft versus host suppressive medications, and you should not have any active graft versus host disease going on. So depending on those, yes patients can get CAR T post. And, in fact, I’ve had a couple of patients who’ve had CAR T after allotransplant.

Lisa Hatfield:

Great, thank you. I’m sure that’ll give this patient some hope. Are there any studies showing that treatment can be tapered? Tapered to by daily, once 90 percent reduction in myeloma has occurred with various therapies. So in general, you may know what medication this patient’s talking about, but is that possible to do that, to taper therapy?

Dr. Sikander Ailawadhi:

So, absolutely, first of all, in myeloma care, Lisa, you had mentioned initially that as somebody went to maintenance, they have had induction. So there are these terms used for categories of treatment, induction, consolidation, maintenance. But if the disease gets controlled adequately at a certain time point, the treatment can be modified to a maintenance. It depends on the regimen.

Some regimens, for example, we are able to get rid of the steroids after a certain time and then in certain regimens the drugs can be reduced in dose or frequency, et cetera. All of the drugs we use have maintenance regimens and maintenance doses. But I should put a word of caution there. I see very frequently that the moment the labs improve, this quote unquote “maintenance” is brought in.

That’s not the right way to do things. The right way is to go back to the clinical trial based on which this regimen was started. And according to that clinical trial, after however many cycles of treatment the maintenance was supposed to happen, it should happen. So if I’ll very quickly say if somebody stays, starts on a regimen and within four months their M spike comes down, and now it has plateaued. Because our drugs are so good that they work that fast. And somebody says, “Okay, four months of that is enough, let’s save it for the future. Let’s go to maintenance.” I would say, “Absolutely not.”

In fact, there is data suggested from a couple of regimens that if significant modifications were made prior to one year of the regimen, then the outcomes were inferior. And I’m not going in specific regimens and I’m not saying that that is applicable to everything, but what I’m saying is, yes, maintenance and tapering is possible. In fact, there are clinical trials looking at even stopping medication. But when and how that change is to be made is very very important. It’s critical. If your physician is not comfortable about that time point, reach out to a myeloma specialist. They should be able to guide when and how to reduce or taper or put on maintenance.

Lisa Hatfield:

Thank you. And that’s very important what you said about induction therapy. Go back to the clinical trial and look and see what the clinical trial said as far as how long that treatment should last because it is exciting as a patient when you start seeing those numbers dropping exponentially. They’re just plummeting, and you want to go off it, you don’t feel great. It’s hard to stay on a therapy for 6 to 12 months that you don’t really enjoy and nobody really does. So that’s important. And then maybe talk about maintenance therapy later. It would be nice to have limited duration maintenance, sometime in the future for induction therapy. Stick with what the clinical trial says. So, okay, this patient is asking another really important question, “I have myeloma and now my daughter does as well. She’s 37, is multiple myeloma hereditary?”

Dr. Sikander Ailawadhi:

I’m sorry to hear about this situation and I’m so sorry that your daughter who’s 37 got diagnosed. There is a small, very small number of very young patients and I’m saying using this term very young, which is just a generic thing that I’ve said because myeloma median age of diagnosis 68. I saw a patient who was diagnosed at 33 and they’re 40 now and they’ve already gone through every single thing that they can think of. And we were talking about clinical trials. So, typically myeloma is not hereditary. It is not something that is passed along through the generations. But what I would say is that there is, if this sort of a situation is happening that you have myeloma and now your daughter has it at a young age, it is important for you to consider getting genetic counseling.

So a genetic counsel for them to be able to look deeper into it. There is not a very standard specific test, so for me to say, Hey, you go and get this genetic test done and that’ll find out this mutation, whatever. But it’s important to get, go through some genetic counseling for them to be able to look a little bit deeper, some next-generation sequencing, what is called germline testing or somatic testing. They should be able to compare both the parent and the daughter’s disease as well as what’s called germline, which is their native DNA, which they were born with, to see if there is anything that jumps out of that. But that would be important to go through at a larger cancer center or if that service is available through your local physician also. That would be great.

Lisa Hatfield:

Great, thank you. Well, I think that’s it for our questions. That’s all that we have time for. But Dr. Ailawadhi, thank you so much for once again, being part of our Patient Empowerment Network START HERE Program. Because it really is these kinds of conversations that help patients, me included, feel more empowered to take questions back to our providers and our healthcare team. So thank you so much for joining us and thank you out there to everybody who’s watching this program, we appreciate you and we appreciate your time and expertise.

Dr. Sikander Ailawadhi:

Thanks and I look forward to the next time.

Lisa Hatfield:

Thank you. I’m Lisa Hatfield. Thank you for joining this Patient Empowerment Network Program and we look forward to seeing you again soon.

Lisa Hatfield:

So with both CAR T and some of the bispecifics approved, obviously if a patient comes in and they need something right away, they’ll take whatever is first available. But all things being equal, if a patient says, well, I can, I have both CAR T accessible and bispecifics accessible. There are some patients out there, I’ve spoken with some who are wondering, is there a benefit to sequencing one before the other, or are there any trials looking into that?

Dr. Ola Landgren:

There are studies that have allowed patients to go on treatment with one of these modalities. For example, the bispecific antibodies with the prior exposure to a CAR T-cell therapy. There are also trials with CAR T-cell therapy that has allowed patients who have been exposed to prior antibodies, either bispecifics or the conjugated antibody drug conjugates, Belantamab mafodotin. So if you look at those studies and see how the numbers compare, if you are not exposed or you are exposed, I think the data is not entirely clear-cut.

There is no definitive study. Some data suggests that maybe it’s not that different, but then there are some studies that suggest that if you go to the antibody first that maybe that would lower the efficacy of the CAR T cell. So some people have for that reason said the CAR T cell should be done first. To make it even more complicated, there are some studies that have then taken time into the equation. So that means that you could have the patient treated with the antibodies for BCMA and CD3, and the antibody is given successfully for a long time, for many years. And eventually, unfortunately, the antibody may stop working.

Now, if you switch back to back to a CAR T-cell therapy without any other therapy in between, some studies indicate that that’s less likely to be beneficial. But if you instead do another target, say you did GPRC5D/CD3, or you did a completely different therapy with small molecules or you did carfilzomib (Kyprolis), or you did venetoclax (Venclexta), or IMiDs, or different types of combinations that are out there, been around for a long time, and you get good mileage out of those combinations.

Now, if that stops working, if you now go to this other therapy, you go back to the CAR T cell, that will suggest that the results are not that different. So I think that there are aspects that we don’t fully understand. I personally believe, based on what I’ve seen, based on what I know from treating thousands of patients with myeloma for almost 30 years I’ve been a doctor, I think time is probably very, very important. So if you go back to back from one therapy to the other, that’s less likely to be beneficial. If you go from one therapy, and it stops working and go to the other drug with the same target.

But I would say it’s not that different from how we think about IMiDs or proteasome inhibitors. If you were to go single drug with a proteasome inhibitor and you switch to single drug with another proteasome inhibitor, or the same thing with an IMiD, that’s less likely to work versus if you went to something else in between. So we just need to generate more data and learn. Lastly, I want to say that in my experience, from all I see in my clinic at the current time, I think the choice that patients make is based on personal preference and to some degree also the situation of the patient. I saw a patient yesterday, 50 years old, who came from another country and has relocated to us here in Miami and asked, what are the options?

And we talked about CAR T cells, we talked about bispecifics. And considering all the different factors that CAR T cell would imply that we had to give some other combination therapy for two or three cycles while we harvest the CAR T cells and manufacture the CAR T cells and then plan for the admission and give it, and also that the patient was not really very happy about the side effects in the hospital with CAR T cell. That patient shows the bispecific, but I’ve also seen other patients in the same situation saying, I’d rather do these different steps for two or three months, I stay in the hospital, and then I enjoy being off therapy.

Actually, I saw another patient just a few days ago, a gentleman in his upper 70s who we had the same conversation, and he had picked the CAR T cells. And I saw him with his wife and he has been off treatment for two years doing excellent. So different patients make different decisions. And I think that is just how the field is evolving. So I think we should be open to individual patient’s priorities and what they want, and we should just offer everything. And of course, we can guide if a patient wants us to give direction, but I think presenting it and let patients be part of the decision-making, that’s the future of how medicine should be practiced.

Transcript:

Lisa Hatfield:

Dr. Landgren, what are the key biological processes driving disease progression and evolution of multiple myeloma, and how can we target these processes to prevent disease relapse and improve long-term outcomes?

Dr. Ola Landgren:

So that’s a very good question. So I think in a nutshell if you use genomics, which refers to the genetic changes that you can see in the plasma cells, there are certain features that the myeloma cells have. They have the copy number changes, that’s the gains and losses of chromosomes. You can find these if you do FISH and cytogenetics could be, for example, gain of chromosome 5 or gain of chromosome 7 or gain of chromosome 11. That would be part of the hyperdiploidy disease, or you have loss of chromosome 13 or 13q deletions. We also refer to 17p deletion. These are copy number changes, they’re extra or loss of these chromosomes. But then you have also the structural variance where you have the translocations of chromosome 14, chromosome 14 harbors the IGH locus, which regulates the making of immunoglobulins.

Plasma cells make immunoglobulins. For reasons that are not entirely clear. The translocations in myeloma that include IgH, they are partnering up with oncogenes. There is a list of oncogenes, there’s MATH, there’s three MATHs, A, B, C. There’s FGFR3, MMSET, and there’s also Cyclin D1 that are on the list. So these are the different types of structural variants that you can see with FISH probes. What people have understood less about are something called mutational signatures. And myeloma is made up by eight distinct mutational signatures that you can see in every single patient. And what that means is that you can, if you conduct whole genome sequencing and you look at all the base pairs, you can see there are certain number of combinations. C can be swapped for A and C can be swapped for G or C can be swapped for T, T can be A and T can be C and T can also be G.

Those are the combinations. So there are four different base pairs, but if you, because the DNA is double-stranded, these are the only possibilities that mathematically that you can see. Now if you look for every base pair and you look on one base pair on the left and one on the right, we call that 5 and 3 prime, you look through triplicates, every of these base pairs can have these different swaps I mentioned. Mathematically, there are 96 different combinations that you can come up with. That’s it.

If you don’t go through the entire genome from left to right, you see that there are these recurrent eight signatures that are there in every patient. So although we don’t understand why they are and exactly how they function, the fact that you see them in every patient tells us that this has to have something to do with the biology of the disease. It must have a role in the control of the disease. We are starting to see that there is one signature that’s called APOBEC. That signature seems to be very important for resistance to treatments. And you can see that APOBEC can be more or less expressed.

And if APOBEC is very expressed, we see that there are lot of mutations in the cells. We have seen in patients with the chemotherapy that APOBEC can be very expressed. When we treat with four drug combinations, it can be very expressed. And what I’m saying, when I say it can be expressed, these are in the patients that relapse out of these therapies. We have also seen that in CAR T cells and bispecifics. So that makes me believe and our group believe that the cells use some form of what we call tumor intrinsic defense mechanism to protect themselves from whatever therapy we use.

It doesn’t matter if it’s immunotherapy, chemotherapy or small molecule therapy, there are some fundamental programs the cells can turn on. We need to understand that better and we are spending a lot of time trying to drill into this. Lastly, I also want to say there was a fourth class of genomic events called complex events that you can see in myeloma, something called chromothripsis. That’s a very severe genomic lesion, is a ripple effect through the genome. There are a lot of havoc going on. And the first time we saw that, we thought this has to be something wrong with this sample. But when we look through more and more samples, we see that about a quarter of the patients actually have this chromothripsis.

So the bottom line is, it’s time to stop doing FISH, it’s time to do more advanced sequencing, ideally whole genome sequencing, but a step towards a whole genome could be to do whole exome sequencing. But there are companies saying that you can do whole genome sequencing for $1 in the future. So that’s really what needs to happen. We need to have better tools to better understand and then we can use this to better understand how to differentiate the therapy and have an individualized treatment. That’s what I talked about with the IRMA model.

Lisa Hatfield:

All right, well, thank you so much for that explanation. Dr. Landgren, can you speak to the advantages that bispecific antibodies offer over traditional therapies, and how do you see their role in overcoming treatment resistance?

Dr. Ola Landgren:

Well, the bispecific antibodies is a novel way of engaging the immune system to go after the myeloma. So if you think about the other antibodies we have, we have three other antibodies. We have daratumumab, we have isatuximab (Sarclisa), we have elotuzumab (Empliciti), they are naked antibodies. They bind to the myeloma and on the backend of these antibodies, there is something called the FC receptor that attracts cells, NK cells, for example, also T cells, and they also attract, some of these antibodies also attract complement and they also by themselves send what’s called a death signal into the myeloma cell.

The bispecific antibodies are very different. They bind and they don’t send death signals, they don’t engage with the complement. What they do is that they have another arm sticking out that binds to the T cells. That’s a CD3 arm and there’s an open pocket. So when a T cell passes by, it grabs the T cell. And now you have a T cell linked to the antibody sitting next to the myeloma cell and the T cell will kill the myeloma. T cells can be very aggressive and kill the myeloma. You just hold them together, it’s like a matchmaker.

And if you think about how CAR T-cell therapy is designed, you take out the T cells, you manufacture them to have a special antenna receptor on their surface, and then you give them back again. And then they bind, this receptor binds to myeloma cells. So in the setting of a CAR T-cell therapy, the T cell sits next to the myeloma cell, but that’s because the T cells were taken out of the body, manufactured to have this receptor that then finds the myeloma cell. But the bispecific antibody, that they don’t require the T cells to be taken out, to be modified this way.

You just use your existing T cells in your body and these antibody just binds to the T cells and the myeloma cells in the body. So it’s sort of a little bit mimics what the CAR T cells do, but it does it in its own way within the cell, within the tissue in the body. You asked me for resistance mechanism and how they are better. Well, I think the best answer I can give you is to say that the overall response rate for the bispecific antibodies are very high. They are 60 to 80 percent single drug compared to the current trials. And if you look and see the trials that have led to approval for the other existing drugs, they were 20 or 30 percent.

So the overall response rate is much higher for the bispecifics than they were for the other existing drugs. We don’t really know exactly how to use them, I would say. What’s the optimal dosing schedule? We give them weekly, it may be every other week, and maybe monthly, eventually, I would think. And should they be combined with which drugs? That’s ongoing investigation. Other questions are, can they be stopped? Can you monitor patients off therapy for a long time? Will some patients never have the disease coming back? We hope so, but we don’t know. Or would it be patients could be off therapy for a long time, like with CAR T cell? Could that happen with the bispecifics? It’s possible.

And if you were to monitor with blood-based tests and you see that there is reappearing disease, would you then put patients back on the therapy? These are questions we…there are a lot of questions, we don’t have answers to all these, but that’s where I think the field is going. A lot of people, including us, are trying to investigate this.

Lisa Hatfield:

Hello, and welcome. My name is Lisa Hatfield, your host for this Patient Empowerment Network START HERE program where we bridge the expert and patient voice to enable you and me to feel comfortable asking questions of our healthcare teams. The world is complicated, but understanding your multiple myeloma doesn’t have to be. The goal of this program is to create actionable pathways for getting the most out of myeloma treatment and survivorship.

Today I am honored and really excited to be joined by Dr. Ola Landgren. Dr. Landgren is chief in the Division of Myeloma and the Department of Medicine, and also serves as director of the Sylvester Myeloma Institute at the University of Miami’s Miller School of Medicine. Dr. Landgren, it’s such a pleasure having you today.

Dr. Ola Landgren:

Thank you very much for having me. It’s really a great pleasure to be here today.

Lisa Hatfield:

So in this program, first, we’ll get a high level update from Dr. Landgren on what the latest myeloma news means for you and your family. And then we will launch into some questions that we’ve received from you. Dr. Landgren. We’re at a pivotal moment in the history of multiple myeloma. We’re experiencing an unprecedented wave of progress marked by significant increase in new treatment options and ongoing research. We are very honored to have your expertise to guide us in understanding these advancements and providing clarity around all the evolving landscape of myeloma care.

So before we get started, to you at home, would you please remember to download the program resource guide via the QR code. This is where you’ll find useful information to follow before the program and after. So we are ready to START HERE. Dr. Landgren, can you speak to the emerging and exciting myeloma therapies and trials right now?

Dr. Ola Landgren:

I’ll do my best. There are so many things to talk about, and I don’t think we have 10 hours, so I will have to shorten it. But I would say that the past 12 to 18 months, we have had three new drugs approved in the field of myeloma. These are the bispecific antibodies. The first out of those three was the BCMA-CD3 targeted drug teclistamab-cqyv (Tecvayli). And in the middle of 2023, we had both talquetamab-tgvs (Talvey), and elranatamab-bcmm (Elrexfio) approved. Talquetamab has another target is GPRC5D with CD3. And elranatamab is similar to teclistamab with the BCMA-CD3 targeted bispecific antibody. These are amazing drugs. They have been found in patients that have been heavily pretreated to result in about 60 percent or more percent of patients responding.

So overall response rates ranging from 60 percent to 80 percent in various trials. We have now these drugs approved, they’re still only approved as single drug and there are new trials going, combinations of two of these or these drugs with other drugs such as daratumumab (Darzalex) or IMiDs, such as lenalidomide (Revlimid) or pomalidomide (Pomalyst). So a lot of drug development is ongoing as we speak. We also have the CAR T cells that are reasonably new drugs. We, you think about everything new every week there’s a new drug, but they are very new CAR T cells.

We have had them for about three or so years, three-and-a-half years. And, the two drugs that are approved in that setting is, ide-cel (idecabtagene vicleucel) [Abecma]. That was the first and then cilta-cel (ciltacabtagene autoleucel) [Carvykti], that was the second. They both go after BCMA similar to the two antibodies I mentioned, teclistamab and elranatamab because they are CAR T cells, that indicates that they are cells.

They come from the same person who’s going to receive them back as treatment. So you collect the cells from the blood and you manufacture them into to CAR cells. So chimeric antigen receptor T cells, and then you give them back. There are several new CAR T-cells in development. There are other targets in development, GPRC5D, for example. There are additional other targets and there are also dual targeted cell therapies in development.

There are also allogeneic CAR T cells in development and that means that you could have a product off the shelf. So someone could donate cells, they could be manufactured into CAR T cells, and then you could give them to technically any person, so it doesn’t have to be the same person collecting and then manufacturing, giving them back. So that would shorten the time window for production.

And there are a lot of other details also that are important in this context. The whole manufacturing process that’s currently four to six weeks is being improved. There are some technologies that can make the CAR T cells in 48 hours, but the turnaround time is maybe one to two weeks with all the control steps, but that’s still a huge improvement. And then you have the antibody drug conjugate if you want.

So then you have the belantamab mafodotin (Blenrep). That actually was the first BCMA targeted therapy we had in myeloma. And then the drug was approved on an accelerated approval study. But when the randomized study was completed, it turned out that it was not better than the control arm. The company took it off the market. And now what’s happening is that there are two new trials, and one of them was just reported in the beginning of February of 2024.

The other one was around the ASH meeting in 2023. These two trials show that if you combine it with other drugs, the most recent one was with bortezomib-dexamethasone (Velcade-Decadron), that was superior with the belantamab mafodotin with bortezomib-dexamethasone versus daratumumab with bortezomib-dexamethasone. So I think we will probably see this drug coming back to the myeloma field. It is currently available as compassionate use, so physicians can prescribe it, but these trials will most likely, I would think, lead to FDA approvals with these combinations.

And lastly, I would say that other exciting trials, there are so many trials going on, but another thing that I think is interesting and exciting is also the use of antigens. And you can use mRNA and things like that. So these are like the vaccines. You can either, take a patients’ myeloma cells and look what they have on the surface, you can make more traditional vaccines or you can use more sophisticated newer technologies just like how the COVID vaccines were developed. And you can inject these sequences and then they will translate into spike proteins where the immune system could go after myeloma cells.

We don’t yet have a product like that in the myeloma field, but there are a lot of biotech and groups that are working to see. Moderna, was actually initially a cancer vaccine company and then COVID came and they turned into a COVID company, and now they’re be back again in the cancer field. So that’s a little bit of a summary of a lot of the exciting news that’s out there.

Lisa Hatfield:

Thank you. And do you have any comments about the sequencing of some of these? So with both CAR T and some of the bispecifics approved, obviously if a patient comes in and they need something right away, they’ll take whatever is first available. But all things being equal, if a patient says, well, I can, I have both CAR T accessible and bispecifics accessible.

And of course, we can guide if a patient wants us to give direction, but I think presenting it and let patients be part of the decision-making, that’s the future of how medicine should be practiced.

Lisa Hatfield:

Thank you so much for that explanation. I’m going to segue into a comment that I always make to myeloma patients. As Dr. Landgren was explaining all of these treatment options, he is on top of all the latest and greatest news and therapies. I always recommend to myeloma patients newly diagnosed or otherwise to seek out at least one consult from a specialist. If you have difficulty accessing care, then a lot of places can do video conferencing, but even that one consult to see a myeloma specialist is so important in your care and treatment options. So I’ll just throw that out there, Dr. Landgren, as a myeloma specialist that you are, we appreciate your expertise in explaining that so well.

Dr. Ola Landgren:

I agree 100 percent with what you said, and I would like to add to that and say, going to a specialist center and it doesn’t have to be here, can really really help. It can be a lot of small things. There is data indicating that survival is longer for patients who have access to specialists. That has been published in the Journal of Clinical Oncology. The Mayo Clinic has published that, I think it was more than one year longer survival.

That by itself is, of course, very strong, but I also think that there are a lot of the small things like the different types of pre-medications, the drugs that are given around myeloma drugs. Could you decrease the dose of some of these drugs like the dexamethasone? Could you get rid of Benadryl if you give the antibodies? These may look as small things, but they can make a huge difference for quality of life.

We have a lot of people coming for second opinions, and we always say if you live closer to someone that you trust, you should go back and be treated there. You can always reach out to us. We are happy to be involved. You have us as a backup. We can be your quarterback if you ever need us. I think that is absolutely the best advice for every patient. Go and get feedback and if you’re not sure about the feedback you get, you could always have two different quarterbacks and you could ask them. I don’t think having 10 or 20 is going to help, but having one or two second opinions, I think is a good decision.

Lisa Hatfield:

That’s really helpful information, thank you, Dr. Landgren. So I think we’re going to shift a little bit to managing and monitoring multiple myeloma. Once you’ve had a patient go through the induction therapy, what kind of monitoring do you complete for your myeloma patients and in particular those who have reached a certain level response and are maybe on maintenance or continuous therapy, what type of tests do you do and how often regarding labs, imaging, bone marrow biopsies?

Dr. Ola Landgren:

There are a lot of different ways, obviously, of practicing medicine. So every center has developed models that they feel very comfortable doing. So I like details. I like to know things. I like to check things. I’m not excessive in ordering invasive tests, but I like to know. Also, I like to make sure the patient not only has good long-term clinical outcomes, but also good quality of life. And to me, I try to minimize the intrusiveness of what we do. So, for example, if I give a combination therapy where there is an injection or infusion, say week one, week two, week three, and then there is a week off. I recognize that if you do labs during that week off, you will have a better yield and understanding of how these three different injections or infusions actually have moved the disease forward and suppressed the disease.

But in my mind, I think that week off is a very important week off for the patient. So I would rather do testing the third day of the treatment at the treatment unit. So if it’s week one, week two, week three, I would draw the myeloma labs that same day. And that would give the patient six more days off from injection, infusion that third week and the whole fourth week off. So I would give the patient 13 days off.

Again, these are small things. These are things I’ve thought about a lot. I’ve practiced medicine for many years and I recognize that having time off like that, many patients travel, they go on vacation, they do different things. So I don’t want to just randomly put a blood test in the fourth week just because I want to check after week one, two, three, and then have the assessment.

I sort of underestimate the benefit of the therapy and then I start the next cycle, say back to back cycle two and cycle three and so forth. I would typically do blood tests once a month following these principles. I do baseline and I would do the last day of injection or infusion. For a newly diagnosed patient, you ask me, I would for baseline always do bone marrow biopsy and an aspirate. I would always do a PET-CT for every patient as my default. Sometimes we end up doing MRI. So that could be other things that are happening, but that is what we do for the majority of our patients.

After we have completed four to six cycles of treatment for patients that are candidates for consideration of transplant with chemotherapy with melphalan (Alkeran), we would usually do a biopsy after four to six cycles and we would use that to determine what’s the optimal mobilization protocol for stem cells. When we do that, we would run a MRD test.

We would run our in-house flow cytometry test that we developed when I used to work at Sloan Kettering and we have developed that here in Miami as well. We work closely with Sloan Kettering, and we have set up this assay in collaboration in the new 2.0 version. We will also send the aspirate for the clonoSEQ at Adaptive Biotech, which is the DNA-based sequencing for MRD. We would send the patient for collection of stem cells.

When the patient is back, we will continue treating. So if you say we do it after four cycles, we would collect, if we do it after five or six, then we collect. After that, we would typically resume therapy and for the majority of our patients, we actually give around eight cycles of therapy, and we have seen that you can deepen the response. You don’t increase the toxicity, but you deepen the response for the vast, vast majority of our patients. When we have used our best therapies, we have done it that way…

We have even published on this, over 70 percent of our patients are MRD negative, and many of those patients, when they come to cycle eight, they ask, do I have to do the transplant? And that is a controversial topic. But I think there are two large randomized trials that have shown the same thing, that there is no survival benefit with transplant. But you can also say that there is, in those two trials, a progression free survival benefit, meaning that the disease would stay way longer with transplant.

But many patients say, if I reach MRD-negative, both those two trials show that if you’re MRD-negative without transplant, or you’re MRD-negative with the transplant, PFS was actually the same. And given that there is no survival, overall survival benefit, why would I subject myself to go to that? Why don’t I keep the cells in the freezer and go right to maintenance? And we will have a conversation with every patient, they would meet our transplant team, they would meet our myeloma expert team.

And the individual patient will make decisions. I think over time, more and more patients have chosen to keep the cells in the freezer. For patients that are MRD-positive, we would counsel towards transplant, but there are patients that don’t want to do that, and we are not forcing any patients to do that. We would give patient maintenance, and on some of our trials, we use the standard of care, which is lenalidomide maintenance.

And we are also developing new approaches where we have done daratumumab added once a month with lenalidomide. We have gone one year, and we have started to do two years of that. And after that, we would stop daratumumab and just do lenalidomide maintenance. Lastly, to answer your question fully here, we would do a PET-CT in the bone marrow after the eight cycles as a repeat, and we would offer a patient to check on maintenance on an annual basis, and this is in accord with the NCCN guidelines. So a lot of details here, but you asked me how we do testing.

Lisa Hatfield:

Yes. And one of the questions that comes up, too, regarding bone marrow biopsy, so you talked about patients kind of through the process of myeloma treatment, perhaps they’ve reached a point where they’re going to be for a while. Do you see a need for continued bone marrow biopsy, say, annually, or is there some benefit to using the newer tests that are being investigated, like mass spec testing and some of the newer ones, I think the EuroFlow? Do you think that that can be used to test for bone marrow biopsy? And how will that be used to monitor the myeloma if a patient is doing relatively well, or do you still like to do bone marrow biopsies on a regular basis? And I know every specialist is different in how they’ll answer that question.

Dr. Ola Landgren:

So what’s known in the literature is that there is no study that definitively has compared annual biopsies with these blood-based tests that you mentioned, showing that they can replace the bone marrow. Those tests or those studies have not yet been published and shown in a convincing way that we have done. This is how it is. It’s still an open question. We don’t know the answer for sure. So our take has been to offer patients to repeat it on an annual basis for maybe two or three and sometimes up to five years. I don’t think we would do biopsies every year for five, 10, 15 or more years. At some point, you have to ask yourself, what are we trying to chase here?

But I think the data we’re looking at that we have published on this and others have also show that if you are MRD-negative after completion of the eight cycles with or without the transplant, the patient that are MRD-negative one year later, they are more likely to be free from progression 10 years later, compared to the ones where you only check once and you don’t know what happened one year later. And that is frankly because there is a small group of patients where MRD-negative could bounce back into positive.

So to check after completion after eight cycles and to check after one more year on maintenance, I think gives us more confidence in thinking about if we eventually could step down and maybe even stop the maintenance at the long term. There is no study that definitively has proven that, but the data suggests that being negative after eight and do another year and even if you do two years out, those are very strong indicators that the disease will stay away long term.

So that’s our justification for offering it, but we would never force any patient. And I also want to say that we have thought about for a long time, how we can contribute to the field and how we can advance the field for blood-based tests. So we are here in Miami, developing a lot of these technologies, and I have made a promise that we will make all these available for all patients that come here to Miami as part of our standard workup. Because they are not clinically validated tests, they will have to be reported for now as research tests, but we will share the information with individual patients.

So we have three different platforms for now. And we are working on the fourth one. So one of them is the mass spec with MALDI, where we can screen the blood with lasers. And we can increase the sensitivity by maybe hundred times compared to existing immunofixation assays. The second is something called clonotypic peptides, which is a more sophisticated way to run mass spec, which is probably up to thousand times more sensitive than immunofixation. And the third technology we are doing or setting up right now is circulating cells that we sequence.

And this is the Menarini technology that is approved for certain other solid tumors. I think for GI malignancies, it’s FDA cleared, but we are doing it in myeloma. We are also looking for free circulating DNA. We’re working with New York Genome Center to set those types of assays up. So my thinking is, if we can offer every patient that come here to do it, and many of those patients will do an annual biopsy, we actually will have the database that can answer the question you asked me, if it can replace. There is no other way that this can ever be answered.

But having a large database, we actually can compare on a patient level, how the bone marrow biopsy with flow cytometry and sequencing, how that behaves in relation to the blood base. How does it perform? Is any of these better? Can they replace each other? So I think if we do this for one or two years, we will have the answer to the question. That’s why I want to do it.

Lisa Hatifeld:

So that kind of leads to the next question that is really an exciting area. I know it’s not necessarily new, but newer is artificial intelligence.  And I know I was reading an article about one of, that you and your colleagues have worked on a newer project and I don’t know if you pronounce it IRMMa or not, but using these large databases to help predict I think, it’s the response of treatment in some patients. So can you talk about that a little bit and tell us about that development and what developments are exciting with artificial intelligence in cancer, in particular myeloma?

Dr. Ola Landgren:

Yeah. So you mentioned the study we just published. We published a model that we call IRMMa and that stands for individual risk prediction for patients with multiple myeloma. So what we were thinking was at the current time, all the existing models are pretty much providing the average patient’s predicted outcome. So think about it is like it’s a probability measure. So you say, if I take this about therapy, what’s the predicted average outcome for patients that take this therapy, say, five years later? So on average, say 70 percent of patients are free from progression. That sounds pretty good. The problem is that you don’t know if you are in the group, 70 percent group that didn’t progress or if you’re in the 30 percent that did progress.

So where are you as an individual? So it’s almost like looking at the weather app on your phone. If it says it’s a 70 percent probability of sunshine and then you go outside and it’s raining, it’s because it didn’t say that it’s 100 percent probability of sunshine. So if you think about another situation would be, say, in a GYN clinic, if a woman were to come and ask the doctor, am I pregnant? Yes or no? You couldn’t say it’s 70 percent probability. You would say, yes, you’re pregnant or not pregnant.

So for myeloma, we have for a long time been living in these weather report systems where we say 70 percent or 30 percent. And we want to go in the other direction of the pregnancy test, where we actually can say for someone with this particular disease profile, with this treatment, this is where this is going to take us. We worked on this project for almost four years and we worked with a lot of other groups around the world that have a lot of data. And they have graciously agreed to collaborate with us and share their data sets. The beauty with this collaboration, there are many beauties of it, but one of them is that people don’t treat patients the same way.

And that actually has allowed us to say for patients that have a particular biological or genomic makeup, if you’re treated this way or that way or the other way or a fourth way and so forth, which of these different treatments would make patients have the longest progression and overall survival? So if you have a large database, you can actually ask those questions. So you can say that you profile individual patients in full detail and you put them in detailed buckets instead of grouping everybody together.

And now if you add a new case, if a new patient is being added and you say, which bucket would this individual fit? Well, this is the right biological bucket. You can then use this database to say out of all the different treatment options, which treatment option would last the longest, which would give the best overall survival? Other questions you could ask is also, for example, you have a patient with a certain biological workup or makeup. And you say, if I treat with these drugs, will the addition of, say, transplant, will that prolong progression for his survival?

And you can go into the database and the computer will then say, I have these many patients that have this genomic makeup and these many people that were treated with this treatment with transplant versus the same treatment without transplant. There was no difference in their progression or overall survival. So then the computer would say, it doesn’t add any clinical benefit, but there could be another makeup where the answer is opposite, but transplant actually would provide longer progression for his survival. I think the whole field of medicine is probably going to go more and more in this direction. So what we want to do is to expand the number of cases.

So we are asking other groups around the world, if they have data sets with thousands of patients, they could be added to this database and we could then have more and more detailed information on sub types of disease and more and more treatment. So it will be better as we train it with larger data sets. The model is built as an open interface so we can import new data. And that’s also important because the treatments will continue to change. So we, for example, say I have a patient that has this genetic makeup. I was thinking of using a bispecific antibody for the newly diagnosed setting.

How is that going to work? The computer will say, I don’t know, because we don’t have any patients like that in the database because that’s not the data, type of data that currently exists from larger studies. But let’s say in the future, if there were datasets like that, you could ask the computer and the computer will tell you what the database finds as the answer. But if you go for another combination, if that’s in the database, it would answer that too. That is where I think the field is going.

And lastly, I would say we are also using these types of technologies to evaluate the biopsies, the material. We work with the HealthTree Foundation on a large project where we are trying to use computational models to get out a lot of the biological data out of the biopsies and also to predict outcomes. So I think artificial intelligence is going to come in so many different areas in the myeloma field and probably in many, many other fields in medicine.

Lisa Hatfield:

Thank you so much, Dr. Landgren, for that broad overview of myeloma, especially relapsed and refractory myeloma. So it’s that time now where we answer questions we’ve received from you. Please remember that this is not a substitute for medical care. Always consult with your medical team. And we’re going to jump right into some questions that we’ve received from patients, Dr. Landgren, if you have a little bit of time to answer these questions for us.

Dr. Ola Landgren:

Of course.

Lisa Hatfield:

Okay. So broad questions. We try to make them broad so they apply to most people, but this patient is asking Dr. Landgren, what are the key biological processes driving disease, progression and evolution of multiple myeloma, and how can we target these processes to prevent disease relapse and improve long-term outcome?

Dr. Ola Landgren:

So that’s a very good question. So I think in a nutshell if you use genomics, which refers to the genetic changes that you can see in the plasma cells, there are certain features that the myeloma cells have. They have the copy number changes, that’s the gains and losses of chromosomes. You can find these if you do FISH and cytogenetics could be, for example, gain of chromosome 5 or gain of chromosome 7 or gain of chromosome 11. That would be part of the Hyperdiploidy disease, or you have loss of chromosome 13 or 13q deletions. We also refer to 17p deletion. These are copy number changes, they’re extra or loss of these chromosomes. But then you have also the structural variance where you have the translocations of chromosome 14, chromosome 14 harbors the IGH locus, which regulates the making of immunoglobulins.

Plasma cells make immunoglobulins. For reasons that are not entirely clear. The translocations in myeloma that include IgH, they are partnering up with oncogenes. There is a list of oncogenes, there’s MATH, there’s three MATHs, A, B, C. There’s FGFR3, MMSET, and there’s also Cyclin D1 that are on the list. So these are the different types of structural variants that you can see with FISH probes.

What people have understood less about are something called mutational signatures. And myeloma is made up by eight distinct mutational signatures that you can see in every single patient. And what that means is that you can, if you conduct whole genome sequencing and you look at all the base pairs, you can see there are certain number of combinations. C can be swapped for A and C can be swapped for G or C can be swapped for T, T can be A and T can be C and T can also be G.

Those are the combinations. So there are four different base pairs, but if you, because the DNA is double stranded, these are the only possibilities that mathematically that you can see. Now if you look for every base pair and you look on one base pair on the left and one on the right, we call that 5 and 3 prime, you look through triplicates, every of these base pairs can have these different swaps I mentioned. Mathematically, there are 96 different combinations that you can come up with. That’s it.

If you don’t go through the entire genome from left to right, you see that there are these recurrent eight signatures that are there in every patient. So although we don’t understand why they are and exactly how they function, the fact that you see them in every patient tells us that this has to have something to do with the biology of the disease. It must have a role in the control of the disease. We are starting to see that there is one signature that’s called APOBEC. That signature seems to be very important for resistance to treatments. And you can see that APOBEC can be more or less expressed.

And if APOBEC is very expressed, we see that there are lot of mutations in the cells. We have seen in patients with the chemotherapy that APOBEC can be very expressed. When we treat with four drug combinations, it can be very expressed. And what I’m saying, when I say it can be expressed, these are in the patients that relapse out of these therapies. We have also seen that in CAR T cells and bispecifics. So that makes me believe and our group believe that the cells use some form of what we call tumor intrinsic defense mechanism to protect themselves from whatever therapy we use.

It doesn’t matter if it’s immunotherapy, chemotherapy or small molecule therapy, there are some fundamental programs the cells can turn on. We need to understand that better and we are spending a lot of time trying to drill into this.

Lastly, I also want to say there was a fourth class of genomic events called complex events that you can see in myeloma, something called chromothripsis. That’s a very severe genomic lesion, is a ripple effect through the genome. There are a lot of havoc going on. And the first time we saw that, we thought this has to be something wrong with this sample. But when we look through more and more samples, we see that about a quarter of the patients actually have this chromothripsis.

So the bottom line is, it’s time to stop doing FISH, it’s time to do more advanced sequencing, ideally whole genome sequencing, but a step towards a whole genome could be to do whole exome sequencing. But there are companies saying that you can do whole genome sequencing for $1 in the future. So that’s really what needs to happen. We need to have better tools to better understand and then we can use this to better understand how to differentiate the therapy and have an individualized treatment. That’s what I talked about with the IRMA model.

Lisa Hatfield:

All right, well, thank you so much for that explanation. Dr. Landgren, can you speak to the advantages that bispecific antibodies offer over traditional therapies and how do you see their role in overcoming treatment resistance?

Dr. Ola Landgren:

Well, the bispecific antibodies is a novel way of engaging the immune system to go after the myeloma. So if you think about the other antibodies we have, we have three other antibodies. We have daratumumab, we have isatuximab (Sarclisa), we have elotuzumab (Empliciti), they are naked antibodies. They bind to the myeloma and on the backend of these antibodies, there is something called the FC receptor that attracts cells, NK cells, for example, also T cells, and they also attract, some of these antibodies also attract complement and they also by themselves send what’s called a death signal into the myeloma cell.

The bispecific antibodies are very different. They bind and they don’t send death signals, they don’t engage with the complement. What they do is that they have another arm sticking out that binds to the T cells. That’s a CD3 arm and there’s an open pocket. So when a T cell passes by, it grabs the T cell. And now you have a T cell linked to the antibody sitting next to the myeloma cell and the T cell will kill the myeloma. T cells can be very aggressive and kill the myeloma. You just hold them together, it’s like a matchmaker.

And if you think about how CAR T-cell therapy is designed, you take out the T cells, you manufacture them to have a special antenna receptor on their surface, and then you give them back again. And then they bind, this receptor binds to myeloma cells. So in the setting of a CAR T-cell therapy, the T-cell sits next to the myeloma cell, but that’s because the T cells were taken out of the body, manufactured to have this receptor that then finds the myeloma cell. But the bispecific antibody, that they don’t require the T cells to be taken out, to be modified this way.

You just use your existing T-cells in your body and these antibody just binds to the T cells and the myeloma cells in the body. So it’s sort of a little bit mimics what the CAR T cells do, but it does it in its own way within the cell, within the tissue in the body. You asked me for resistance mechanism and how they are better. Well, I think the best answer I can give you is to say that the overall response rate for the bispecific antibodies are very high. They are 60 to 80 percent single drug compared to the current trials. And if you look and see the trials that have led to approval for the other existing drugs, they were 20 or 30 percent.

So the overall response rate is much higher for the bispecifics than they were for the other existing drugs. We don’t really know exactly how to use them, I would say. What’s the optimal dosing schedule? We give them weekly, it may be every other week, and maybe monthly, eventually, I would think. And should they be combined with which drugs? That’s ongoing investigation. Other questions are, can they be stopped? Can you monitor patients off therapy for a long time? Will some patients never have the disease coming back? We hope so, but we don’t know. Or would it be patients could be off therapy for a long time, like with CAR T cell? Could that happen with the bispecifics? It’s possible.

And if you were to monitor with blood-based tests and you see that there is reappearing disease, would you then put patients back on the therapy? These are questions we…there are a lot of questions, we don’t have answers to all these, but that’s where I think the field is going. A lot of people, including us, are trying to investigate this.

Lisa Hatfield:

Okay, thank you. And we have a number of questions about MRD testing, so I’m going to try to combine those all together. Basically, what the questions are asking is how do you interpret MRD testing with regard to prognosis, treatment response, and maybe even like treatment, ongoing treatment? How do you use those results in your clinic or any comments you might have on the MRD test?

Dr. Ola Landgren:

So MRD tests have been around for quite some time. We have been pioneers pushing it. We have worked on it for over 15 years. We worked with the FDA to see if MRD could eventually become an endpoint for drug approval, that’s work in progress. The FDA will make those decisions. There are a lot of trials that use MRD as a secondary endpoint to see how it correlates with progression-free survival. And there actually are some trials that have been using it as a cool primary or primary endpoint in the absence of FDA’s decision to accept it. But that is probably going to change in the future. We will see.  What have we done in the clinic? Well, we have used it in the same way as we have done with PET-CTs and the regular blood work. So if you use SPEP IFE light chains and you see there is residual disease after you have delivered your planned treatment, people have used what’s called consolidation therapy.

So we have done the same with the MRD test. If there is someone who has a little bit of disease left, we have tried to see if we could make that patient MRD-negative. We have also used it as a tool to build more reassurance. I mentioned before for patients who get this new combination therapies, if they are not very keen on jumping right to chemotherapy with Melphalan and transplant, if they want to collect the cells and keep them in the freezer, using the MRD as a tool to guide for reassurance.

Looking at the randomized trial showing that MRD negativity with or without transplant seems to have the same progression-free survival and in the absence of overall survival, either way, that has been published. But we would always say to patients, there are no definitive studies that have shown that this is how it is. It’s still an area of investigation. So if a patient wants to sort of do everything by the traditional book, we would give every step in the therapy and not pay attention. But a lot of patients say, I would rather monitor, and if I have to do these more toxic therapies, I wouldn’t do it. But I will use MRD to build confidence in myself.

Lisa Hatfield:

Well, thank you so much, Dr. Landgren, these have been great questions, and I actually have another half sheet of questions that we don’t have time for, because that’s all the time that we have. Dr. Landgren, thank you so much, it’s been a pleasure talking with you today. So thank you for joining our Patient Empowerment Network START HERE program. This has been an excellent discussion. Thanks to all of you, for your questions and tuning in. My name is Lisa Hatfield. I’ll see you next time.

Dr. Ola Landgren:

Thank you very much for having me. Thank you.

Lisa Hatfield:

Oh, great. Okay. Again, important to see a myeloma specialist to tease out all this information. Thank you. All right. This patient is asking, “I’m 81 and living with comorbidities. The myeloma was diagnosed after bone marrow test. How is treatment fitness determined?” And also a question about that is if you’re given an ECOG status of something you don’t like it, can that be improved after you’ve had treatment?

Dr. Sikander Ailawadhi:

Absolutely.

Lisa Hatfield:

Maybe be eligible for a trial or something.

Dr. Sikander Ailawadhi:

Correct. Correct. That is so important. When this patient mentioned that they’re 81-year-old and they’re living with comorbidities, I think, so when I’m talking to a patient who’s new to me, it’s very important for me to try to tease out what was their performance status or their fitness status prior to myeloma. Because my goal is to try to get them as close to that as possible.

Now if this patient is saying that they were already quite frail before the diagnosis of myeloma and myeloma is added to the frailty, then it becomes a little tricky because we’re starting in a difficult spot. We do determine fitness by asking questions, simple questions like, what can a patient do at baseline? Can they do grocery store or grocery shopping by themselves? Can they walk around the block? Do they get short of breath? Et cetera.

And frankly, there are 81-year-olds who are playing golf every day and are fitter than me. So I’m just saying that age by itself is not the criteria. And, Lisa, like you rightly mentioned, if there are fitness issues coming from the disease itself, then that’s the time that we actually have to work with the treatment, get the treatment started, and then assess the fitness a couple of months later, a couple of cycles later. Because the treatment may have worked and may have improved the fitness quite a bit.

Transcript:

Lisa Hatfield:

Okay. So what would be the next steps, Dr. Ailawadhi, for a patient who’s had CAR T and reaches a relapse state or is relapsed?

Dr. Sikander Ailawadhi:

Yep. This is something, unfortunately is the truth of the matter in myeloma at least that we are, we don’t seek cures. We have had some long remissions. I have, for example, patients who are now reaching three, three-and-a-half years of remission on CAR T treatment who received it on clinical trials even before they got FDA-approved.

But, unfortunately, the disease does come back. So what happens is, we are seeing data that the novel, other novel immunotherapies like bispecific antibodies, even the ones who go after the same target as CAR T, BCMA targeting bispecifics, they do have some response rates, good response rates in post CAR T setting. So the bispecific antibodies by themselves may give us 60 to 65 percent response, but in the post CAR T setting, that response might go down to 40, 45 percent. So less responses, but still possible.

There are also bispecific antibodies. There is one available, which is not against BCMA, it is against GPRC5D. That’s a bispecific called talquetamab-tgvs (Talvey). So a novel target. There is…there are of course a lot of clinical trials. There are some clinical trials that are even looking at CAR T post-CAR T. So different kind of a CAR T. Those clinical trials are going out. So what I would suggest is that if your disease progresses after CAR T-cell treatment, you should very strongly consider getting to a specialist myeloma center and get an opinion like you mentioned, Lisa.

That is so important because the choice of treatment is extremely important at that time. And we are trying our best to sequence all the options we have, in a way, actually one of my patients mentioned, one of these days, ”Hey, does that mean that I’m basically buying time till something new and exciting comes along?” And I said, “In a way that is true. That we are trying to stretch all our treatments and get to the point that something new and promising just like CAR T comes, and hopefully we get longer benefits again.”

Lisa Hatfield:

So when you say there’s a possibility of CAR T and then a post-CAR T maybe a second CAR T. Would that be a different target then?

Dr. Sikander Ailawadhi:

So there could be a different target. I have, in fact, I saw a patient who had received one CAR T in a clinical trial and then they were subsequently able to receive a CAR T standard of care, which had been FDA-approved. So they used different CAR Ts, but one was in clinical trials and one was standard of care.

How is Treatment Fitness Determined in Multiple Myeloma?


Transcript:

Lisa Hatfield:

So we have another patient asking, “Do myeloma patients require multiple prior therapies prior to being eligible for CAR T?” And what’s the rationale for not implementing CAR T immediately, which probably has to do with FDA approval based on clinical trials at this point?

Dr. Sikander Ailawadhi:

So any drug, let alone CAR T, any drug can only be given in the situation that it is approved by the FDA. So basically in accordance with that drug’s FDA approval label. Currently, CAR T-cell therapy is approved in the U.S. after at least four prior lines of therapy. And the patient must have had treatment with at least one proteasome inhibitor, for which we have three drugs, bortezomib (Velcade), ixazomib (Ninlaro), and carfilzomib. They must have been treated with at least one prior immunomodulatory drug; lenalidomide (Revlimid), thalidomide (Thalomid), pomalidomide.

And they must have been previously treated by at least one monoclonal antibody, daratumumab (Darzalex) or Isatuximab (Sarclisa). Once the patient has had all these criteria met, they’ve become a candidate for CAR T-cell therapy. Frankly, we cannot just use a drug anywhere because we cannot use a drug where it has not shown to be of benefit. And importantly, it has not shown to be of any risk. So CAR T-cell therapy in the first line setting is being studied in clinical trials, but is not FDA-approved. Currently approved only after four prior lines, but the FDA is reviewing data for both the CAR Ts to see if they may be available sooner. As of right now, that approval is still pending.

Lisa Hatfield:

Okay, thank you. We’re hopeful that that will happen soon.

Dr. Sikander Ailawadhi:

Hopeful.

Lisa Hatfield:

Yeah. So an interesting question from a patient, “Does CAR-T therapy actually change one’s DNA?”

Dr. Sikander Ailawadhi:

No. The CAR T therapy does not change one’s DNA. What happens is, there are T cells taken out of a patient. The DNA of those T cells is modified and then those T cells are given back to the patient. Those T cells do not go and integrate into your other healthy body cells or your stem cells, et cetera. Those T cells, it’s almost like giving a boost of immunity, which is targeted against your myeloma. So those T cells go in and they fill those myeloma cells.

Now we hope that those T cells perpetuate and teach or create some memory T cells and that immunity lasts a little bit longer. But all of that genetic modification stays within the T cells. It does not integrate anywhere else. Now, I know there was a previous question about T-cell lymphomas, that is related to this question in a way because the risk that is theoretical is, that that genetic modification in the T cells might make those T cells replicate uncontrollably leading to a T-cell cancer or T-cell lymphoma. But I’m saying that this is theoretical because while it is possible, it happens extremely rarely and even in the cases where the cancer happened, it has  been seen that the cancer may not come from that portion of the DNA that was…that’s where the modification was done. So, low risk.

Lisa Hatfield:

So how is myeloma survivorship evolving, and what’s different now than it was five or 10 years ago in terms of treatment planning?

Dr. Sikander Ailawadhi:

Yeah, I think it’s very important to keep that in mind. When I see a newly diagnosed patient, I’m not just telling them, “Hey, this is your induction therapy, and your transplant is the goal.’ We’re trying our best to decide that patient’s life journey with myeloma over the next 10, 15 and hopefully more years. So we’re trying to pick and choose the regimen that is most likely going to help the patient the most today and most likely will give a longer duration of the response.

So when you say survivorship, that also very importantly brings up the point that patients are living with myeloma longer. We have to manage their health overall. So looking for any side effects from treatment, managing them very well so the patient is able to stay on the treatment and maintain good quality of life.

There are actually, clinical trials looking at stopping treatment when there is a very deep, prolonged response. Again, going towards survivorship and giving the patient’s quality of life. There is looking for other cancers. In fact, I had a patient in the clinic and we were talking about just myeloma in general and I was telling them, “Okay, please remember you may not want to do a colonoscopy, but you already have one myeloma cancer diagnosis.

The risk of subsequent cancers is always there in any cancer patient.” So that was a male person. So I said, “Okay, please do not miss your colonoscopy. Please do not miss your prostate screening and whatever is age-appropriate must be done.” So managing everything because myeloma is not a sprint, it’s a marathon.

We want to make sure that we pace ourselves well so we manage all the symptoms, all the signs. Bone health becomes much, much more important because the same bone structure is now going to carry us longer and many more years. And as you rightly said, planning, which treatment comes first, which comes next, when does CAR T come? It’s not that everybody must get CAR T today. That’s not the answer. So what to use when becomes extremely more important.

Lisa Hatfield:

Dr. Ailawadhi, can you speak to the latest news and priorities in the rapidly expanding myeloma treatment landscape?

Dr. Sikander Ailawadhi:

I think, Lisa, that’s an excellent and important question. Because as you rightly mentioned, there is such a large amount of data that is coming through for myeloma all the time. I mean, it’s almost, we kind of talk about the fact that every time you turn your shoulder or look over your shoulder, there is a new drug approved. So I can imagine this can be very overwhelming. So what I’ll say is that in my opinion, there are some categories of new data that are pertinent and important for our patients.

The two or three out of them that come to my mind, one is what’s called CELMoDs, or there are a couple of agents there called iberdomide, mezigdomide. These are showing some interesting data. Important to keep in mind that they are somewhat related to the immunomodulatory drugs lenalidomide (Revlimid), pomalidomide (Pomalyst), but they’re showing benefit in patients who have had len and pom before and have progressed. So exciting stuff there.

We’re also seeing some interesting data about newer CAR Ts and bispecific antibodies. They are all coming up with some benefits in some cases. I think it’s important to keep in mind that the bispecifics are landing at the 60 to 70 percent response rate, and CAR Ts are typically landing at the 80 to 90 percent response rate, but there are more agents expected.

There are also some newer bispecifics in different classes, like one of them is called cevostamab, which is an FcRH5 inhibitor or targeting bispecific. So newer bispecific, not just more of the same category. And there has also been recent data about Bcl-2 inhibitors, which have been traditionally used for patients with translocation 11;14.

There have been some negative data, negative as in trials, which did not pan out with a drug called venetoclax (Venclexta), but there are two other drugs that had some recent data shown from different companies, which were exciting information. So in my mind, those are kind of the broad new drug categories. There is another, a couple of other quick things that I’ll mention.

One is we’re getting more and more information about real world experience with these new drugs. It’s good to see that CAR Ts are panning out very similar in the real world as they are in clinical trials. We’re also seeing that the side effect profile of a lot of these newer novel immunotherapy drugs is similar as seen in the clinical trials.

Racial ethnic disparities are something which are very close to my heart, and there is more and more information coming out in that. Unfortunately, highlighting the disparities more still rather than yet coming up with solutions. And I think the last thing that I feel which has been recent has been at the American Society of Hematology meeting in 2023, which was in December in San Diego. One of the myeloma studies actually became a plenary session presentation, which is a pretty big deal for any disease area. So one thing is that it gets highlighted. Secondly, it was a combination of a regimen called isatuximab-irfc (Sarclisa) with carfilzomib (Kyprolis), lenalidomide, and dexamethasone (Decadron) in newly diagnosed patients.

It’s a randomized trial, Phase III, which was presented. I think the important part is we saw unprecedented deep responses and patients in much, much higher numbers than before becoming MRD-negative. So very deep responses. So these are kind of some very broad, but lots of highlights that I talked about.

Lisa Hatfield:

So can you also talk about some of the newer tools for myeloma progression and relapse and what patients might want to know about that? And in particular, maybe talk a bit about MRD testing and the role of MRD testing for patients who relapse.

Dr. Sikander Ailawadhi:

Excellent question. Lisa, I think the first and foremost thing an important part for our patients to learn is what are their “tumor markers,” for the, or disease markers for myeloma. We can follow myeloma by either the M spike or monoclonal protein, by light chains, by monoclonal protein in the urine or blood. And it’s important to keep that in mind because every now and then we’ll see patients who say, Hey, my ratio changed. So I’m progressing. Well, that comes after the light chains change. So it’s important to understand the role of these things. So M spike in the urine, M spike in the serum and light chains. One of them is typically the marker for a patient.

Now the MRD status or minimal residual disease that is looking for one cell, one myeloma cell from amongst 100,000 cells in the bone marrow. So it is looking at a very deep level. The most important benefit of MRD testing right now is to understand that if a patient turns MRD negative, then they have a superior outcome. Their prognosis is better. Their progression free survival, or the time before their disease comes back is longer. 

But when a patient is MRD-negative and is being followed or maintenance or whatever, if the bone marrow turns MRD-positive, then that might be the sign that the disease might be coming back. Right now, we do not keep switching drugs to get to MRD-negative. That is not the goal of treatment. The way to think about it is we want to get to MRD-negative, but that means it’s incumbent upon us to try and pick a regimen that is more likely to get to MRD-negative. That’s the way to think about it.

Let’s pick a regimen more likely to get us into MRD-negative and hope that we get to MRD-negative. We see every now and then that the patients keep switching regimens just to get to MRD-negative. That’s not the way to go because you’re just using up options too quickly, too fast. A common question that patients ask is, well, does that mean I need to get annual bone marrow biopsies and MRD testing? Probably not.

That’s too much testing. So what I suggest is that once somebody has turned MRD-negative, it’s important to keep an eye on every single thing. Now, change in any of the routine labs, imaging, new symptoms, etcetera. That’s when we switch to the bone marrow again and see if the patient has turned MRD-positive. There are clinical trials going on right now which are stopping drugs based on repeat MRD negativity or starting drugs on MRD positivity. But those are clinical trial questions.

Lisa Hatfield:

So along those same lines, since you’re a Mayo physician, I’m curious about the mass spec testing. So if a patient say has been MRD-negative for some time, still wants to monitor at a deeper level, even though it’s not commercialized yet, do you see a role for mass spec testing on a regular basis in the future and being rolled out to community facilities also?

Dr. Sikander Ailawadhi:

Absolutely, Lisa. I did not specifically bring it up because mass spec is not, like you rightly said, is not yet commercially available. Now we’re doing mass spec quite frequently at Mayo Clinic. Basically mass spec is taking up a blood sample. Important to keep in mind, it’s not a bone marrow test, it’s a blood test, but it looks for those abnormal proteins based on the protein weight at a much, much lower level. Our SPEP or serum protein electrophoresis does not pick up very small quantities of the protein mass spec does. So in an essence, the mass spec, if somebody is negative on that, turning mass spec negative to mass spec positive may be an earlier sign of the disease coming back rather than the SPEP yet turning positive. But as you rightly said, it is not yet commercially available. I do see the benefit of it.

There is more and more data coming in favor of it, and there was data that was also at ASH. So I do see that in the future we’ll be able to most likely have it available more widely. At this point, it is just a blood test to attempt to check the disease level at a much deeper level and be able to notice if the disease is progressing sooner than our currently available tools.

Lisa Hatifield:

Hello and welcome. My name is Lisa Hatfield, your host for this Patient Empowerment Network START HERE program, where we bridge the expert and patient voice to enable you and me to feel comfortable asking questions of our healthcare teams. The world is complicated, but understanding your multiple myeloma doesn’t have to be. The goal is to create actionable pathways for getting the most out of myeloma treatment and survivorship.

Joining me today is Dr. Ailawadhi, back by popular demand. Dr. Ailawadhi is a respected multiple myeloma expert from Mayo Clinic. Dr. Ailawadhi’s career focus includes the treatment of plasma cell disorders like myeloma and understanding the epidemiology and pathophysiology of this disorder. It’s always such a pleasure having you, Dr. Ailawadhi. I’m really excited you’re joining us again. So thank you for joining us.

Dr. Sikander Ailawadhi:

And thanks a lot for having me, Lisa. This is excellent. I look forward to this next iteration of the Patient Empowerment Network START HERE program.

Lisa Hatfield:

Thank you. So before we dive into today’s discussion, please take a moment to download the program resource guide using the QR code. This guide contains pertinent information to guide you both before and after the program. And this program will provide you with a comprehensive update on the latest myeloma news and its implications for you and your family. Following that, we’ll launch into some questions that we have received from you.

So let’s start here. Dr. Ailawadhi, at this juncture in myeloma history, we are witnessing unprecedented activity, a surge of new treatment options, and a wealth of insights. Today, we are privileged to have your expertise to help us decipher these developments and shed light on the advancements shaping the landscape of myeloma care. First, we’re going to get a high-level update from Dr. Ailawadhi on what the latest myeloma news means for you and your family. And then we’re going to talk about some questions that you’ve sent in. So let’s get started with the high-level update, Dr. Ailawadhi. Can you speak to the latest news and priorities in the rapidly expanding myeloma treatment landscape?

Lisa Hatfield:

Great. Thank you. And as a patient, I like to have one more data point that they can get from my blood, not from my bone marrow to assess the disease. So thank you for explaining that. Regarding survivorship, patients are living longer with myeloma in general because of the novel therapies that have come out in the past few years. So how is myeloma survivorship evolving, and what’s different now than it was five or 10 years ago in terms of treatment planning?

Dr. Sikander Ailawadhi:

Yeah, I think it’s very important to keep that in mind. When I see a newly diagnosed patient, I’m not just telling them, “Hey, this is your induction therapy, and your transplant is the goal.’ We’re trying our best to decide that patient’s life journey with myeloma over the next 10, 15 and hopefully more years.

Bone health becomes much, much more important because the same bone structure is now going to carry us longer and many more years. And as you rightly said, planning, which treatment comes first, which comes next, when does CAR T come? It’s not that everybody must get CAR T today. That’s not the answer. So what to use when becomes extremely more important.

Lisa Hatfield:

Thank you for that. And thank you, Dr. Ailawadhi, for that important reminder. All of you watching, get your regular screenings, like he said, prostate cancer, mammograms, colonoscopies, get it done. So thank you for that.

One of the things that comes up with that regular, not regular screening, but monitoring after certain therapies for future malignancies, there’s 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 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:

Great. Thank you so much for explaining that. And for any of you out there watching this, Dr. Ailawadhi is a myeloma specialist, and I highly encourage anybody who is looking at CAR T therapy or even for a first consult for myeloma, seek out even one consult from a myeloma specialist. It is so important in trying to understand these therapies and any fears you may have regarding those therapies and the risks of that. So really appreciate that, Dr. Ailawadhi. Thank you. So I think it’s time now to start answering questions from patients that we received from all of you in the audience.

Please remember, this is not a substitute for medical care. Always consult with your medical team. And we are going to jump right in, Dr. Ailawadhi. We have a lot of questions from patients here and I’ll just start with the first one. This patient is asking, my M spike keeps rising in spite of chemo. What can I do?

Dr. Sikander Ailawadhi:

Very important question, Lisa. Every patient must understand what their disease marker is. This patient is asking about the M spike, which is the monoclonal spike, whether it’s in the blood or in the urine. And if the M spike is continuing to increase and there is a significant increase, significant is defined by at least 25 percent from the nadir or from the bottom most point with the, at least a absolute increase of 0.5 gram per deciliter. So half a gram per deciliter. So we want a 25 percent increase, but we also want at least 0.5 gram per deciliter.

So if somebody had an M spike of one at their best point, then the increase to 1.5 is significant. If somebody had the M spike of 0.2, then it’s not the 25 percent increase, it’s the 0.5 that must happen. So they hit 0.7 and that’s a significant increase. So that’s how we think about M spike, 25 percent with an absolute of at least 0.5 gram per deciliter.

If that is indeed happening, this would be considered a biochemical progression. And at that point, it should be considered to switch around the treatment because we don’t want the disease to grow to the point that there are actually symptoms showing up or organ damage happening. We want to be able to capture the disease progression sooner and act upon it.

Lisa Hatfield:

Great, thank you. Do you have any recommendations for people who, as we might have some patients watching this, who are light chain only? Any guidelines on if those numbers are rising?

Dr. Sikander Ailawadhi:

That’s an excellent question too. So if somebody has light chains as their marker, we are looking at an increase in the involved serum free light chain. So if somebody has kappa as their marker, the kappa is going up, or if they have lambda as the marker, the lambda is going up. Typically, if both of them go up, that is not disease progression. That could be coming from kidney dysfunction. Somebody is dehydrated and they get labs checked. Both kappa and lambda might be elevated. Again, a 25 percent increase in the absolute. But at the same time, we are also looking at at least 10 milligram per deciliter change.

So if somebody had a light chain of two milligram per deciliter, if it goes to 12, that might be a significant change. But I can say that light chains are a little bit more volatile and they do get affected by our fluid status. So if I ever notice a patient with a light chain increase, I’m more likely to repeat the test very soon, maybe even at a couple of days, one week interval, just to make sure that there is a trend rather than just a fluctuating light chain.

Lisa Hatfield:

Okay. Thank you for that information.

Dr. Sikander Ailawadhi:

And I should maybe, very quickly add, we do not check light chains in the urine. Light chains should be checked in the blood. Urine light chains are very nonspecific and there’s no need to test them.

Lisa Hatfield:

Okay. That’s helpful also. So patients don’t have to walk around with their big orange jugs full of fluids. So thank you. All right. This might be a complicated question to answer. But in general terms, for those who relapse for the first time, what are the best treatment options?

Dr. Sikander Ailawadhi:

I think that’s a very important, and I can imagine a scary situation. So somebody who relapses in general, not just even the first time, the factors that are taken into account for deciding what treatment they should get, there are broadly three categories of factors. Patient factors deciding what’s the age, what’s the other comorbidities, are they diabetic, are they heart disease, kidney dysfunction, because those things go into the decision of what may or may not be given. So patient factors.

Also importantly, how close are you to your treatment center? Can you come in for infusion or injection drugs time? And again, can you prefer or do you prefer oral drugs only? Et cetera. Those things become important. Then that…so that’s patient factors and disease factors. How fast is the progression? Is it high-risk disease, standard risk disease? Is it biochemical progression like the previous person asked?

Or is it actually a clinical progression in which there’s kidney dysfunction or anemia or bone disease? Because the choices and the urgency of treatment may change. So patient factors, disease factors, and then drug factors are the third class or third category, which is what have you had before? How long have you been on it? Are you on maintenance or not? Is your disease considered refractory to a certain agent, meaning resistant to a certain agent? Typically, if you were on a treatment and your disease is progressing, that same drug may not be used again.

And there are some times that we will reuse a drug, but generally not. We can use the same class, but we may not typically use the same drug. So I think the choice of treatment depends on all of those factors put in. And then we come up with one or two or three regimens and we discuss them with patients. And, of course, being an academic, physician, I must say there is always, you must always seek out good clinical trials if they’re available to you. That is the way our field moves forward.

Lisa Hatfield:

Yes, thank you for that information. So we have another patient asking, “Do myeloma patients require multiple prior therapies prior to being eligible for CAR T?” And what’s the rationale for not implementing CAR T immediately, which probably has to do with FDA approval based on clinical trials at this point?

Dr. Sikander Ailawadhi:

Absolutely. You’re absolutely right, Lisa. So any drug, let alone CAR T, any drug can only be given in the situation that it is approved by the FDA. So basically in accordance with that drug’s FDA approval label. Currently, CAR T-cell therapy is approved in the U.S. after at least four prior lines of therapy. And the patient must have had treatment with at least one proteasome inhibitor,  for which we have three drugs, bortezomib (Velcade), ixazomib (Ninlaro), and carfilzomib. They must have been treated with at least one prior immunomodulatory drug; lenalidomide, thalidomide (Thalomid), pomalidomide. And they must have been previously treated by at least one monoclonal antibody, daratumumab (Darzalex) or Isatuximab (Sarclisa).

Once the patient has had all these criteria met, they’ve become a candidate for CAR T-cell therapy. Frankly, we cannot just use a drug anywhere because we cannot use a drug where it has not shown to be of benefit. And importantly, it has not shown to be of any risk. So CAR T-cell therapy in the first line setting is being studied in clinical trials, but is not FDA-approved. Currently approved only after four prior lines, but the FDA is reviewing data for both the CAR T’s to see if they may be available sooner. As of right now, that approval is still pending.

Lisa Hatfield:

Okay, thank you. We’re hopeful that that will happen soon.

Dr. Sikander Ailawadhi:

Hopeful.

Lisa Hatfield:

Yeah. So interesting question from a patient, “Does CAR-T therapy actually change one’s DNA?”

Dr. Sikander Ailawadhi:

No. The CAR T therapy does not change one’s DNA. What happens is, there are T cells taken out of a patient. The DNA of those T cells is modified and then those T cells are given back to the patient. Those T cells do not go and integrate into your other healthy body cells or your stem cells, et cetera. Those T cells, it’s almost like giving a boost of immunity, which is targeted against your myeloma. So those T cells go in and they fill those myeloma cells. Now we hope that those T cells perpetuate and teach or create some memory T cells and that immunity lasts a little bit longer. But all of that genetic modification stays within the T cells. It does not integrate anywhere else.

Now, I know there was a previous question about T-cell lymphomas, that is related to this question in a way because the risk that is theoretical is, that that genetic modification in the T cells might make those T cells replicate uncontrollably leading to a T-cell cancer or T-cell lymphoma. But I’m saying that this is theoretical because while it is possible, it happens extremely rarely and even in the cases where the cancer happened, it has been seen that the cancer may not come from that portion of the DNA that was…that’s where the modification was done. So, low risk.

Lisa Hatfield:

Okay. Thank you very much for that.

Lisa Hatfield:

Okay. So what would be the next steps, Dr. Ailawadhi for a patient who’s had CAR T and reaches a relapse state or is relapsed?

Dr. Sikander Ailawadhi:

Yep. This is something, unfortunately is the truth of the matter in myeloma at least that we are, we don’t seek cures. We have had some long remissions. I have, for example, patients who are now reaching three, three-and-a-half years of remission on CAR T treatment who received it on clinical trials even before they got FDA-approved.

But, unfortunately, the disease does come back. So what happens is, we are seeing data that the novel, other novel immunotherapies like bispecific antibodies, even the ones who go after the same target as CAR T, BCMA targeting bispecifics, they do have some response rates, good response rates in post CAR T setting. So the bispecific antibodies by themselves may give us 60 to 65 percent response, but in the post CAR T setting, that response might go down to 40, 45 percent. So less responses, but still possible.

There are also bispecific antibody. There is one available, which is not against BCMA, it is against GPRC5D. That’s a bispecific called talquetamab-tgvs (Talvey). So a novel target. There is…there are of course a lot of clinical trials. There are some clinical trials that are even looking at CAR T post-CAR T. So different kind of a CAR T. Those clinical trials are going out. So what I would suggest is that if your disease progresses after CAR T-cell treatment, you should very strongly consider getting to a specialist myeloma center and get an opinion like you mentioned, Lisa.

That is so important because the choice of treatment is extremely important at that time. And we are trying our best to sequence all the options we have, in a way, actually one of my patients mentioned, one of these days, Hey, does that mean that I’m basically buying time till something new and exciting comes along? And I said in a way that is true. That we are trying to stretch all our treatments and get to the point that something new and promising just like CAR T comes, and hopefully we get longer benefits again.

Lisa Hatfield:

Thank you for that. So when you say there’s a possibility of CAR T and then a post-CAR T maybe a second CAR T. Would that be a different target then?

Dr. Sikander Ailawadhi:

So there could be a different target. I have, in fact, just yesterday I saw a patient who had received one CAR T in a clinical trial and then they were subsequently able to receive a CAR T standard of care, which had been FDA approved. So they used different CAR Ts, but one was in clinical trials and one was standard of care.

Lisa Hatfield:

Oh, great. Okay. Again, important to see a myeloma specialist to tease out all this information. Thank you. All right. This patient is asking, “I’m 81 and living with comorbidities. The myeloma was diagnosed after bone marrow test. How is treatment fitness determined?” And also a question about that is if you’re given an ECOG status of something you don’t like it, can that be improved after you’ve had treatment?

Dr. Sikander Ailawadhi:

Absolutely.

Lisa Hatfield:

Maybe be eligible for a trial or something.

Dr. Sikander Ailawadhi:

Correct. Correct. That is so important. When this patient mentioned that they’re 81-year-old and they’re living with comorbidities, I think, so when I’m talking to a patient who’s new to me, it’s very important for me to try to tease out what was their performance status or their fitness status prior to myeloma. Because my goal is to try to get them as close to that as possible. Now if this patient is saying that they were already quite frail before the diagnosis of myeloma and myeloma is added to the frailty, then it becomes a little tricky because we’re starting in a difficult spot. We do determine fitness by asking questions, simple questions like, what can a patient do at baseline? Can they do grocery store or grocery shopping by themselves? Can they walk around the block? Do they get short of breath? Et cetera.

And frankly, there are 81-year-olds who are playing golf every day and are fitter than me. So I’m just saying that age by itself is not the criteria. And, Lisa, like you rightly mentioned, if there are fitness issues coming from the disease itself, then that’s the time that we actually have to work with the treatment, get the treatment started, and then assess the fitness a couple of months later, a couple of cycles later. Because the treatment may have worked and may have improved the fitness quite a bit.

Lisa Hatfield:

Great thank you for that. So this person is asking, their husband is starting maintenance therapy, so I am assuming they just finished induction therapy, having leg pains mostly at night. Could this be a form of peripheral neuropathy or is maybe from bisphosphonates or from any of the medications that maybe were used during induction?

Dr. Sikander Ailawadhi:

So, excellent question. So, this is almost going back to that survivorship question that we discussed earlier, that it’s so important to manage the side effects and maintain quality of life. So, a lot of patients with myeloma will say that I have cramping or symptoms or some pins and needles at night more so. Part of it is because body’s at rest, relaxed, things, symptoms become more focused. Yes, it could be peripheral neuropathy, but at the same time certain drugs caused muscle cramping or what’s called myalgias, sometimes maintenance therapies can cause that.

It’s important for somebody to be able to determine is it coming from muscles or nerves? Is it coming because some electrolytes are abnormal. Like one of the common things is low magnesium or low potassium can cause neuropathy, for example, or cramping. I’ve had patients who will get some over-the-counter lotions or some forms et cetera, which are infused with some electrolytes and say that they feel some benefit. So topical things are good. So I think it’s important to figure out is it muscle or nerve and is it coming from drugs or disease? And that’s where your physician can help tease it out.

Lisa Hatfield:

Okay, thank you. So we have a patient who is talking about her genetic abnormalities, but has been through both auto and allo stem cell transplant in the last two years and has relapsed. And is asking, “Can CAR T-cell therapy help me?” And would she even be eligible for CAR T therapy given the allotransplant?

Dr. Sikander Ailawadhi:

That’s an important question. So first of all, sorry to hear that, that your disease is behaving that aggressively, that you’ve had both the transplants in the past two years and still having issues. So yes, CAR T can still be used after an allotransplant. There are some criteria. You should not be on any graft versus host suppressive medications, and you should not have any active graft versus host disease going on. So depending on those, yes patients can get CAR T post. And, in fact, I’ve had a couple of patients who’ve had CAR T after allotransplant.

Lisa Hatfield:

Great, thank you. I’m sure that’ll give this patient some hope. Are there any studies showing that treatment can be tapered? Tapered to by daily, once 90 percent reduction in myeloma has occurred with various therapies. So in general, you may know what medication this patient’s talking about, but is that possible to do that, to taper therapy?

Dr. Sikander Ailawadhi:

So, absolutely, first of all, in myeloma care, Lisa, you had mentioned initially that as somebody went to maintenance, they have had induction. So there are these terms used for categories of treatment, induction, consolidation, maintenance. But if the disease gets controlled adequately at a certain time point, the treatment can be modified to a maintenance. It depends on the regimen.

Some regimens, for example, we are able to get rid of the steroids after a certain time and then in certain regimens the drugs can be reduced in dose or frequency, et cetera. All of the drugs we use have maintenance regimens and maintenance doses. But I should put a word of caution there. I see very frequently that the moment the labs improve, this quote unquote “maintenance” is brought in.

That’s not the right way to do things. The right way is to go back to the clinical trial based on which this regimen was started. And according to that clinical trial, after however many cycles of treatment the maintenance was supposed to happen, it should happen. So if I’ll very quickly say if somebody stays, starts on a regimen and within four months their M spike comes down, and now it has plateaued. Because our drugs are so good that they work that fast. And somebody says, “Okay, four months of that is enough, let’s save it for the future. Let’s go to maintenance.” I would say, “Absolutely not.”

In fact, there is data suggested from a couple of regimens that if significant modifications were made prior to one year of the regimen, then the outcomes were inferior. And I’m not going in specific regimens and I’m not saying that that is applicable to everything, but what I’m saying is, yes, maintenance and tapering is possible. In fact, there are clinical trials looking at even stopping medication. But when and how that change is to be made is very very important. It’s critical. If your physician is not comfortable about that time point, reach out to a myeloma specialist. They should be able to guide when and how to reduce or taper or put on maintenance.

Lisa Hatfield:

Thank you. And that’s very important what you said about induction therapy. Go back to the clinical trial and look and see what the clinical trial said as far as how long that treatment should last because it is exciting as a patient when you start seeing those numbers dropping exponentially. They’re just plummeting, and you want to go off it, you don’t feel great. It’s hard to stay on a therapy for 6 to 12 months that you don’t really enjoy and nobody really does. So that’s important. And then maybe talk about maintenance therapy later. It would be nice to have limited duration maintenance, sometime in the future for induction therapy. Stick with what the clinical trial says. So, okay, this patient is asking another really important question, “I have myeloma and now my daughter does as well. She’s 37, is multiple myeloma hereditary?”

Dr. Sikander Ailawadhi:

I’m sorry to hear about this situation and I’m so sorry that your daughter who’s 37 got diagnosed. There is a small, very small number of very young patients and I’m saying using this term very young, which is just a generic thing that I’ve said because myeloma median age of diagnosis 68. I saw a patient who was diagnosed at 33 and they’re 40 now and they’ve already gone through every single thing that they can think of. And we were talking about clinical trials. So, typically myeloma is not hereditary. It is not something that is passed along through the generations. But what I would say is that there is, if this sort of a situation is happening that you have myeloma and now your daughter has it at a young age, it is important for you to consider getting genetic counseling.

So a genetic counsel for them to be able to look deeper into it. There is not a very standard specific test, so for me to say, Hey, you go and get this genetic test done and that’ll find out this mutation, whatever. But it’s important to get, go through some genetic counseling for them to be able to look a little bit deeper, some next-generation sequencing, what is called germline testing or somatic testing. They should be able to compare both the parent and the daughter’s disease as well as what’s called germline, which is their native DNA, which they were born with, to see if there is anything that jumps out of that. But that would be important to go through at a larger cancer center or if that service is available through your local physician also. That would be great.

Lisa Hatfield:

Great, thank you. Well, I think that’s it for our questions. That’s all that we have time for. But Dr. Ailawadhi, thank you so much for once again, being part of our Patient Empowerment Network START HERE Program. Because it really is these kinds of conversations that help patients, me included, feel more empowered to take questions back to our providers and our healthcare team. So thank you so much for joining us and thank you out there to everybody who’s watching this program, we appreciate you and we appreciate your time and expertise.

Dr. Sikander Ailawadhi:

Thanks and I look forward to the next time.

Lisa Hatfield:

Thank you. I’m Lisa Hatfield. Thank you for joining this Patient Empowerment Network Program and we look forward to seeing you again soon.

Transcript:

Lisa Hatfield:

So one person says, “I’m currently in remission, what can I expect in my future? How long does remission last? And is treatment after remission the same as initial treatment?”

Dr. Kami Maddocks

So that is very dependent on what a patient receives. So there are different kind…of a lot of our treatments we look at median times. When patients have relapse, that can be a little bit different for single agent antibody therapy versus antibody in combination with chemoimmunotherapy for how long that treatment remission lasts. As far as we don’t typically reuse a treatment once we have used it before, although there is data in follicular lymphoma when patients receive single agent antibodies. So rituximab (Rituxan) alone, if they do well with that single agent immunotherapy for a long period, they may receive re-treatment with just that so long as they don’t have disease that requires more aggressive treatment.

Lisa Hatfield:

So is that more likely to happen then if a patient maybe wasn’t refractory to it, if they just stopped using it for some reason? Would that be more common for that to happen to go back on that same drug?

Dr. Kami Maddocks:

So with rituximab, we use it alone and in combination. So there are some patients that don’t necessarily have what we call a large tumor, and they don’t have a lot of lymph nodes, or they don’t have large lymph nodes, but they might be symptomatic from them, or the location might be problematic. And so once these lymph nodes get a certain size, they usually don’t have as good of a response to single agent antibody therapy. But there are patients who have small lymph nodes that aren’t as big but again are causing a problem that can get completely…you give a short course of the rituximab, and it can last for a very long time and then you would consider again using a short course of that rituximab.

The chemotherapies we have, we don’t reuse chemotherapy, for the most part. Some of that, for a while, there was bendamustine (Treanda) if patients got five, six, 10-year remissions out of it. Sometimes they would re-get that chemotherapy. But I think we’ve just seen so many newer therapies approved in the last five six years. Like the bispecifics, the EZH2 inhibitors, lenalidomide (Revlimid), CAR T, we had different PI3K inhibitors available for a while. And so I think it was just that you had the ability to offer a patient something that they never had before, and that is more appealing.

How Has CAR T-Cell Therapy Transformed Myeloma Care?

Transcript:

Katherine:

Yeah. Well, now that we understand a bit more about what it is, let’s walk through the process. When a patient goes through CAR T, what happens first? 

Dr. Richard:

So, the first step is being referred to a CAR T physician. Right now, CAR T therapies can only be done in certain tertiary care institutions, not even all tertiary care institutions.  

They have to have the ability to manage and process cellular therapies. So, that’s limited right there. So, patients have to be referred to centers, so actually do these CAR T kind of therapies. Once they meet with the myeloma physician who deals with CAR Ts as well, then the way it works in our institution is then we assess them for which is the best kind of CAR T product the patient may be eligible for. Are they eligible for clinical trials? Do they fit the profile for clinical trial? Are the patients willing for clinical trails? If not, are they candidates for one of the commercially approved products? As I said, there is specific criteria. Patients have to have had at least four lines of therapy to be able to receive a commercially approved CAR T product.  

If that is the case, and once the process has been explained to the patient, they have to go through all the financials, the insurance approval. These are very expensive propositions. So, the insurance goes through all of the criteria to make sure that they will approve the product. Once the insurance approves, they also going through the institutional approval process to make sure that these are again being done for the right patient, and that they go through the institutional approval.

There are several patient specific characteristics. For instance, we want a patient who has the support structure to be able to support a therapy like this. They have to have a good performance status. They have to be relatively able to be able to handle these kinds of therapies. I went through all of those side effects that are possible. We look at their cardiac status. We look at the neurological status.  

We look at the pace at which their disease is escalating because these are again advanced patients. So, if somebody is relapsing very quickly, they may not have the time to wait to get to a slot for the apheresis, and then to wait again for the manufacturing to happen. So, we look at all of that. We look at their kidney function. And then finally in terms of their psychosocial, do they have their caretakers, the support system? Where do they live? Are they able to access our center? Are they from out of state?

If so, how are we going to manage during those initial months until they’re able, stable enough to be discharged back to their referring physician? So, we look at several things, so we have multiple teams of people, social work, pharmacy who looks at all of these different – and explains the pharmaceutical aspects of all of this, our finance team, our coordinators who put all of this together.  For the apheresis, we are involved with an apheresis team.  

And then the cell therapy lab that processes the cells, the vascular team to put in the lines required for the apheresis. So, there are several, several groups. And then if we need to get a consultation from our expert cardiologist or neurooncologist, we need to have those teams involved as well.  

Katherine:

How long does it take to know whether the treatment has been successful? 

Dr. Richard:

So, we get a sense depending on what their blood markers look like, we can get a sense within the first month if the patient is actually responding to the treatment or not. I generally wait for the first three months to do a actual formal assessment with their bone marrow and their PET scans and everything else because right around then they’ve gone through the initial acute post CAR T period. And so, at the time of the bone marrow we assess what it looks like, we send for a test called MRD which is minimal residual disease to see where they’re at with that. 

And PET scans to look at any areas of skeletal lesions or even extramedullary disease that they may have. So, I would say within the first month we get a sense, but by three months we do that first formal assessment.

Transcript:

Katherine:

Dr. Richard, how is CAR T-cell therapy impacting the landscape of myeloma care? 

Dr. Richard:

So, as I’d hinted or alluded to previously, prior to CAR T cells appearing on the horizon, we had very limited options for patients who had had the first several lines of therapy.  

So, once they had been exposed to two proteasome inhibitors, two iMiDs, and then anti-CD38 antibody which is the three major class of myeloma drugs, they are then called triple class exposed or penta-exposed depending on how many of these drugs they’ve been exposed to.   

We had a study called the MAMMOTH study back – this was published back in 2019 prior to the era of CAR T cells and other T-cell directed therapies. And at the time they had looked at patients who were triple class exposed, and who had been exposed to daratumumab were refractory to daratumumab as their last line of therapy. And what we saw was with their next line of therapy or whatever else was available at the time for patients such as these, their expected response rate was only about 30 percent or so, number one.  

Two, their outlook was very poor with a median progression-free survival which means that the amount of time that patients could go without the disease coming back, and that median progression-free survival was less than six months. And their expected even median overall survival was well under a year. So, that was what the landscape looked like when CAR T cells came onto the scene. For instance, the CART2 trials, which is one of the approved products which is cilta-cel which is what we have now, we actually saw for this same group of patients, the response rate was now 98 percent.  

Deep responses were 83 percent. And we now have the final readout of their median progression-free survival which is almost three years. So, you can see a significant difference.  

Under six months, media progression-free survival to three years. And over 50 percent of the patients were living over three years. So, that’s kind of where we are at. I mean so it was no small improvement. This considerably kind of almost reset the bar and has given a new lease of hope and life to patients who had advance myeloma. And one of the things we say in myeloma is although we don’t, as yet, say that myeloma’s curable, we are working towards that. But we are also giving options for other treatments, other research to be effective in patients just by keeping them around longer.  

Katherine:

Have there been any recent research developments involving CAR T-cell therapy that patients should know about? 

Dr. Richard:

Absolutely. So, much as I have highlighted all the hope and the optimism and the good things about this, the fact is we’re still not curing people with these therapies.  

So, we called this a plateau in the survival curve which means that if we achieve that plateau, that means the disease is probably not coming back, and we have essentially the definition of cured. But we’re not seeing that. We’re still seeing a downslope in the survival curves of myeloma which means that patients are still relapsing in spite of these excellent therapies.

So, there’s a lot of research going on into why are patients still relapsing? Is it because they’re losing the antigen which the CAR T cells are recognizing? Is it because the CAR T cells are no longer effective even though the antigen is still present? Is it because there’s a considerable lag time between the patients being freezed or collected, the cells being collected for the genetic modification in the lab to the time when the patients can actually receive these cells? And that can be anywhere between four to eight weeks.  

So, during this time period, patients with advanced myeloma may not remain static with their disease. The disease is progressing. They’re getting worse. They may not be candidates for these kinds of therapies. So, one of the areas of research is how can we speed up this process, this manufacture process? How can we make it much more available? Because they’re limited by the manufacturing facilities, their abilities to have these viral vectors, to be able to transduce these cells and genetically modify.

So, can we take them off of those kinds of things? Can we automate this? Can we improve these manufacturing platforms? So, a lot of different things are being tested. And then as I’d also mentioned earlier, right now they’re approved for advance myeloma, but what if we can bring them up earlier? Are patients actually going to get cured by that? Are they going to have a much better progression-free survival with that versus waiting until they’re very advanced? So, these are all many, many things that are being looked at.   

In addition, a lot of these CAR T products, these approved products, all them are all recognizing one antigen on the myeloma cell. Now there are products are being looked at that are dual target antigen recognition ability. So, that’s another thing. So, maybe if the CAR T cells are missing one of the antigens, and they’re not able to use that to kill the myeloma cell, maybe the other antigen can pick up the slack. So, these are various things that are being looked at.
