Katherine Banwell:

I’d like to start by learning a bit about you. Can you tell us about your role in the Myeloma Care Team? 

Tiffany Richards:

Yes. So, I’m a nurse practitioner and I’ve been here at MD Anderson for 20 years working with patients with plasma cell dyscrasia. And so, I work in collaboration with our nurse as well as our myeloma physician to not only evaluate patients, what their responses are to treatment but also to make sure that they’re tolerating treatment well, and then adjusting medication or providing supportive medications so that patients are better able to tolerate their therapies.  

Katherine Banwell:

Bispecific antibody therapy is a newer therapy. How has this option changed myeloma care?  

Tiffany Richards:

Between that and CAR T, it’s really offered our patients the opportunity to utilize the body’s own immune system to help fight the myeloma cells. I think the one nice thing that the bispecific antibodies have allowed is that you’ve had a group of patients that maybe weren’t candidates at that time for CAR T either due to other medical conditions or maybe because their disease isn’t at a place where we would be able to get them to CAR T.   

Either maybe their lymphocyte count was low, white blood cells, and so maybe the ability to collect those T cells would be impaired or the disease itself was rapidly progressing and so the patient would not be able to be off therapy in order to have those T cells collected.  

And so, the bispecific antibody allows us to utilize those T cells to go after the myeloma cells without having to go through the process of having to collect those T cells. And so, that has really changed for that group of patients. But also, we have a bispecific antibody therapy that doesn’t target the same receptor that the CAR T-cell therapies do. So, our CAR T-cell therapies target something called BCMA, which stands for B Cell Maturation Antigen.

That’s expressed on the surface of the myeloma cells, and there’s a bispecific that targets a different receptor called GPRC5D. It’s a lot of letters. But it’s a different target, and so even for patients who have had CAR T-cell therapy we can use that bispecific antibody now for those patients who have maybe progressed on CAR T.  And so, it’s allowed another treatment option for patients that they didn’t otherwise have.  

Katherine Banwell:

So, how many bispecific antibody therapies are available for people and how do they differ? 

Tiffany Richards:

So, we have three. So, we have two that target the BCMA; so, that would be teclistamab (Tecvayli) and elranatamab (Elrexfio). And then, we have a third one that targets the GPRC5D which is called talquetamab (Talvey). And so, we utilize the talquetamab if we wanna use a bispecific therapy that does not target the BCMA. And then, for patients who maybe wouldn’t be able to get to CAR T, we might use one of the BCMA therapies.  

And as far as differences between to the two BCMA, really, they’re pretty similar as far as response rates. They haven’t been compared head-to-head. And so, different centers might utilize one versus the other depending on what they have on formulary. So, I would just say, whatever one your center is utilizing that would be the one to go with. 

Katherine Banwell:

Why is a care partner required for patients who are undergoing bispecific antibody therapy?  

Tiffany Richards:

That’s a great question. So, it’s because of some of the side effects that we can see in patients who are undergoing bispecifics. So, similar to CAR T cell therapy, we can see what’s called cytokine release syndrome. We abbreviate that by CRS. And then, we also can see neurotoxicity. We don’t see it to the same degree that we see it with CAR T but patients can still experience it.  

So, cytokine release syndrome, you can get fevers. You can have a drop in the blood pressure, chills, increase in the heart rate. And so, because of that you have to be monitored closely because, if you would start to have cytokine release syndrome, we need to make sure that we’re properly intervening and we can utilize a different medication called tocilizumab (Actemra) to help quiet the immune system a little bit, quiet down those T cells. And so, you need to have somebody that’s with you at all times that knows you, and also, same with the neurotoxicity. Again, we don’t see it to this same degree that we see it with CAR T, but that doesn’t mean that it can’t happen.  

And so, you really need to have that care partner alongside of you. Plus, I think just with these immune therapies, it’s a lot of information that we’re giving patients.   

And so, it’s important to have that other person there to kind of hear what maybe you’re not able to catch. There’s a lot of information that’s being given to you and can be very overwhelming at times. And so, it’s important to have that second person there to kind of be another set of ears as you’re going through this journey.

Transcript:

Katherine Banwell:

Do side effects vary from patient to patient? 

Dr. Craig Cole:

Yes, so they actually vary greatly from patient to patient and from drug to drug. There’s some bispecifics for some cancers that have low risks of cytokine release so low that they don’t even need to come to the hospital. And some of them have such a high risk of those cytokine release syndromes that people are in the hospital for a few days.  

The other thing is usually the more tumor someone has, the more disease and cancer they have, the higher those risks of cytokine release. And so, it does vary from patient to patient to and from medication to medication. 

Katherine Banwell:

What should care partners understand about caring for someone during therapy? 

Dr. Craig Cole:

One of the big things that care partners should look for or to be aware of are – is the timeline for a lot of those symptoms. The highest risk for the side effects, the things to look out for, the neurologic toxicity, the fevers, and shortness of breath, and things are in the first few days of each dose of receiving therapy.  

Some of those therapies actually because of the neurotoxicity, they don’t let anyone drive, any patients drive for the first few weeks after receiving a bispecific. So, knowing the timeline, that in those first few days, that you really have to check the temperature, have a plan, know who to call, watch for those symptoms. But as the weeks move on, like after the second dose, there’s much less toxicity, third dose, even less risk. Fourth dose and on is very rare to have any of those toxicities, and so then you can relax. And usually people are able to drive. So being aware of the timeline’s important. 

Katherine Banwell:

Yeah. Are there advances being made in the management of side effects for bispecifics? 

Dr. Craig Cole:

Oh yes, and so that’s the – that’s one of the really exciting things is the – is what I was just talking to one of our trainees about this, about the evolution of the bispecific antibodies have been to make them more effective, make them more sticky, make them engage those T cells more while decreasing the toxicities. 

And so the ones that we’re seeing that are in clinical trials now that hopefully will be approved soon have less of those side effects, less hospitalization, and actually have a longer frequency of being given. The other thing is that we’re really beginning to learn a lot about treating cytokine release syndrome, especially as severe cytokine release syndrome. So, there was a drug that was used to treat severe COVID called tocilizumab (Actemra).  

Katherine Banwell:

Yeah.  

Dr. Craig Cole:

And that was used when people came in with COVID symptoms which can be a lot like cytokine release. The would receive this medication to help control that. Now we’re using that to treat cytokine release syndrome.  

And there’s quite a bit of data, especially in multiple myeloma in using it prophylactically to prevent cytokine release syndrome. And there are studies that show that the usual rate in multiple myeloma, kind of the specialty that I have, the usual rate of cytokine release – some cytokine release is about 70 percent with using prophylactic tocilizumab, which is just an antibody against one of those cytokines, IL-6. It goes down to – up to about 25 percent, so 75 to 25.  

And really it has no adverse side effects and doesn’t do anything with the outcome or the effectiveness of the bispecific antibodies.  

Katherine Banwell:

Well, that’s an incredible difference, isn’t it? 

Dr. Craig Cole:

Yes, yes, that was really – the trick is trying to get insurance companies to approve it and to get hospital systems to approve it.  

But I am very confident that very soon as we get more data about using it prophylactically that they’ll be incorporating it into the guidelines.

 Bispecific Antibody Therapy | The Important Role of Care Partners

Bispecific Antibody Therapy | The Important Role of Care Partners 

Transcript:

Katherine Banwell:

What is the role of a care partner for someone undergoing bispecific antibody therapy? 

Dr. Craig Cole:

Yeah, the care partner is, I think, a critical component of someone receiving bispecific therapy. And their reason is really to do with the side effects and monitoring the side effects of the therapy. What’s the big side effect of the bispecific antibodies is again when those T cells engage the cancer cells and they find the cancer, they release chemicals to destroy the cancer immediately.  

And those chemicals are from the T cells, can cause people to feel very ill, or can cause them to feel very ill very quickly, or they can have fevers, and they can have difficulty breathing. And that’s called cytokine release syndrome. Cytokines are the chemicals that the T cells are using to kill the cancer cells.  

Release, meaning that T cells are releasing that, and syndrome mean that different things can happen to different people. And the highest risk for the cytokine release syndrome is usually within the first two to three treatments, usually in the first two or three days of the therapy. And a lot of times when people get the bispecific antibodies, sometimes it’s given in a brief hospitalization like an overnight hospitalization, but then they go home.

And then the trick is monitoring for that cytokine release syndrome, the fevers that can be associated with that, shortness of breath, low blood pressure. And in having a couple people observing, watching for those signs and symptoms are really important. Because if cytokine release syndrome isn’t addressed immediately, it can progress to worse outcomes, meaning that the blood pressure gets lower, the difficulty in breathing gets worse.  

If let completely go, people can end up in the intensive care unit which is very, very, very rare. But that’s why we address this as early as possible. The other side effect, and probably kind of the most subtle thing, are some of the neurologic things that can happen with the bispecific antibodies. So, it’s the neurologic toxicity, or some people call it ICANS. And that’s when some of those cytokines that we talked about that are from the T cells can cross the blood brain barrier and cause patients to be confused.  

They can have word finding difficulties. They can feel – almost have stroke-like symptoms. They’re temporary, but they definitely need to be addressed. And sometimes patients may not be aware that they can’t find the right word, or they want to speak, and the words don’t come out, or when they speak it’s the wrong words are coming out.  

And that’s a real, real big sign that you need to call your doctor immediately, or your provider immediately if you have those neurologic symptoms. So, watching for those side effects, so low blood pressure, the high fevers, and stroke like symptoms. It’s not a stroke, but it’s just those chemicals in the brain that can cause people to have some neurologic problems. And again, if you address those immediately, they are definitely reversible.

Transcript:

Katherine Banwell:

Managing the worry associated with a diagnosis or concerns about the future, and we did touch upon that earlier, it can lead to anxiety and fear. Why is it important for patients to share any worries they may be having with their care team?  

Dr. Naveen Pemmaraju:

Well, I love this question. It really wraps up everything we’re talking about here. I believe that part of the journey for the patient does include mental and psychological safety. So, it’s very difficult to make major life decisions when one is not feeling mentally, or psychologically safe. So, that’s what you’re hitting on here. Anxiety, fear, and worry, of course, are a natural and important part of the patient journey with any cancer, much less a rare cancer and blood cancer on top of that. However, sometimes in some patients, it can become so paralyzing, so overtaking, and overwhelming that it may prevent the ability of the patient to receive information, process it, and then make a decision back. Yes, we want people to have caregivers, and power of attorney, all those things are essential, but we also want people to have their own agency in aegis.  

So, I would approach this from three aspects. I really love this question because I don’t think we were addressing it head-on 10 or 15 years ago. One aspect is the disease itself. These MPNs, systemic mastocytosis, eosinophilia, myelofibrosis, PV, ET, all of these MPNs can secrete these cytokines and granules that can mess up the patient’s mindset, even just profound fatigue leading to a slowing down of the neurological process. So, I think underlying control of the disease is something that can affect this. Number two is the side effects from some of these medicines. Interferon is a great example, a wonderful class of drugs that’s been around for decades, treated for solid and liquid tumors, but it has a known side effect of causing brain fog. Some of these issues can even cause depression and anxiety in some people. So, education, mitigation, following these things with dose reduction, that’s an important part.  

A third aspect, Katherine, is actually looking with a counselor and a therapist on the spectrum of this. So, normal, adjustment disorder, depression, for example. What we’ve had as a breakthrough at our center has been the supportive palliative care team. They’ve been phenomenal. So, this is a group of doctors who’s kind of one-third internist, one-third oncologist, and one-third psychiatry support.  

So, rather than the usual consults that we used to do either to psychiatry or to social work case managers, there is this burgeoning field of supportive care medicine which has revolutionized the care, I think, particularly for solid tumor patients and now hopefully for our blood cancer patients. So, I’m able to refer patients for a variety of reasons. There’s a fatigue clinic for overwhelming fatigue. There is obviously depression, and anxiety support, either with medications, talk therapy, or both. Smoking secession for folks who are still smoking and maybe either withdrawing or quitting is causing stress.  

So, it’s a really cool science and if your center has that, that’s something to inquire about. Then lastly, as we mentioned, a nice running theme today, Katherine, is looking for other medical stuff outside of the MPN. I mentioned thyroid earlier. Remember, you have a thyroid abnormality that can cause fatigue, depression, and anxiety, right? So, what’s your TSH thyroid function, and vitamin deficiencies?  

Screening for your other well-person screening exams, looking for solid tumors, looking for other conditions that may be mimicking the MPN, or mimicking one of your other aspects. So, again, it comes down to partnership with the primary care team and looking at that. So, I think those are some of the aspects that I want to mention, but it’s such an important part of the journey. I really have to mention that as well.

Katherine Banwell:

“Can diet play a role in either manifesting the disease and or helping with healing? Also, how important is exercise to the healing?”  

Dr. Naveen Pemmaraju:

I give a lot of credit to this area, to my colleagues, Ruben Mesa, Dr. Angela Fleischman, and Dr. Robyn Scherber. A lot of data that’s come out of these groups, which has shown two major findings in our MPN patients of potential clinical significance. One is as the questioner is asking about diet. It is true that we’re, several studies are pointing towards the anti-inflammatory Mediterranean diet as a potential benefit to our patients with MPN. Lots of different ideas there when they measure cytokines. 

These abnormal protein signatures that are in MPN patients can cause fatigue and some of the bad quality of life can be dramatically improved in some cases by following a strict Mediterranean diet over weeks and months. So, that’s something important. People should check it out. Obviously, diets have to be addressed with each patient and each provider because sometimes a diet may work for someone and not for you because of comorbidities, vitamin deficiencies, electrolytes, etc.  

Then the second aspect, if I may include in this question, is also the concept of yoga/meditation. Dr. Ruben Mesa and others have shown, the same thing, that you can have a potential downregulation of some of these abnormal cytokines. However, the caveat is it must be done right with a guided trainer in a real program over a certain period of time. What I think both of these non-pharmacological interventions tell us is that there are things beyond medicines and pills that may really help our patients in some aspect of the disease.  

Well, if that aspect is fatigue, night sweats, headaches, I think that’s a really important thing. So, let’s say together on this program that these data sets are evolving, they’re interesting, they’re intriguing. For some people, it may be an easy incorporation. Frankly, some people may already be doing these things, but as you ask nicely, let’s include in the discussion non-pharmacologic as we heavily investigate the pharmacologic as well. We’re all open to that. Let’s see the data, and the data is evolving.

Are There Worldwide Links to Aggressive Prostate Cancer?

Transcript:

Lisa Hatfield:

Are there any challenges unique to minority communities that hinder access to advanced prostate cancer treatments and therapies? And do you have thoughts on how these barriers can be effectively addressed?

Dr. Isaac Powell:

I do. First of all, the diagnosis has to be made. And so that’s made by screening, by the PSA testing and digital rectal exams. Now, some people are talking about, well, we don’t need to do the digital rectal exam. That absolutely is not true. You can have a very aggressive cancer and have a normal PSA. We know that the PSA is not 100 percent accurate in diagnosing, predicting that you may have prostate cancer sometimes.

And I’ve had several patients who had normal PSAs, abnormal rectal exams, and as a result, I’m biased with them. If you don’t do the rectal exam and you have a normal PSA, you may miss aggressive cancers. So definitely have your usual rectal exam, excuse me. And once after that, if you have a biopsy, and if it is positive, then again I think that aggressive therapy is the way to go, if you’re in good shape.

Now, people are afraid of cancer. I mean, afraid of surgery. I’ve had surgery, so I can talk to them about what I’ve had and what you go through. Men are also concerned about losing their sexual function and those kinds of things related to the treatment of prostate cancer. And I can tell them that the quality of life is okay after that because we have ways of treating sexual dysfunction, the pill that everybody knows about, as well as injection and penis and ultimately the penile prosthesis. So that can be fixed.

And the other issue of losing control of the urine, that can be fixed as well. And so those are the things I tell people about not specifically among African Americans. There’s the genetic and the biology that I have to discuss, but one of the things that drives these genetic cells is obesity.

Obesity can produce these pro-inflammatory cytokines. So I always advise them to, if they are obese, to reduce their weight and their fat, particularly belly fat. That’s challenging because people have difficulty losing weight. The other thing is exercise. Exercise is a key that I think it is the most important factor in treating many health conditions, exercise. And what exercise does, and this has been studied in breast cancer, it decreases the expression of the genes that I described earlier. In terms of prior driving the cancer and breast cancer, they’ve found it decreases the pro-inflammatory cytokines. I described the tumor necrosis factors IL-6 and IL-8. So that’s important, exercise. So those are the things that I tell patients. And now in terms of advanced disease there are clinical trials that are there.

And we do these trials to decide what’s the best treatment for cancer, even though we don’t have “a cure.” Now, the problem among African Americans is that they don’t trust these clinical trials because of the abuse that African Americans have suffered through slavery and all the other kinds of things when they’ve been treated as less than human, like animals being operated on without having any anesthesia and many other abuses that have occurred. And so there’s this major distrust now that’s very difficult to eliminate in the Black community, especially if there are very few African American doctors to take care of them. So what I think that we have to fix that question of distrust, and that’s going to take a while, but I talk to them always about this mistrust issue, because I can’t see everybody, although we do need more African American doctors and nurses to take care of them and to encourage them to participate in clinical trials and to be seen as a person who is going to be taking care of them in clinical trials, that’s very important.

Often we talk about access to care, but particularly African Americans that mostly live in large cities where there is access to care. But, in terms of one particular example that’s brought up on occasion is what has occurred in Baltimore and other big cities where I talk to an African American, you know Johns Hopkins is right in the middle of the African American community. So it’s not about access again, it’s about mistrust. And I said, “Well, why don’t African Americans go to Johns Hopkins?” Well, she says, “If you walk past Johns Hopkins, they may steal your bodies.” I said, what? I didn’t believe that, but I’ve been reading literature, particularly one called the Medical Apartheid where they talked about African slavery, where they dug up the bodies of slaves to practice the anatomy.

And so that’s where this idea occurred. At night, they would dig up the bodies and do this, and not only in Baltimore, but other cities as well. So again, the mistrust issue is very difficult to resolve because of those issues. And people talk about that, well, I just don’t trust the white healthcare system, period. And don’t want to go until they’re having symptoms, and then they have no choice. They have to go. And by this time, the cancers are more advanced and cannot even prolong life expectancy in those particular patients. So I’m not sure I answered your question in terms of what a person or what I would do to activate participation in the healthcare of advanced disease.

Do the genetics of prostate cancer vary in African Americans? Expert Dr. Isaac Powell from Karmanos Cancer Institute discusses what research has shown about gene expression and what occurs in the body in African Americans versus European Americans.

[ACT]IVATION TIP

“…patients need to take charge by asking questions about the therapy. Again, ‘is it going to cure me, and is the chemotherapy going to cure, immunotherapy going to cure? If not, how long do we think that I will live?’ That’s a good question, that I’d like to know if I were a patient.”

Lisa Hatfield:

So, Dr. Powell, I just read a bit about your really impressive research, particularly with regard to the biology and genetics of prostate cancer. Can you provide an overview of your research focus on how prostate cancer impacts African Americans in comparison to other ethnic groups?

Dr. Isaac Powell:

Yes, I would certainly love to do that. In 2010, we found that the cancer grows faster among African Americans compared to European Americans. And those are the terms we use now, as opposed to Black and white. In science, we use those terms. And so at that point, I thought that this may be driven by the genetics and biology. So in 2013, we used what now has been considered the artificial intelligence.

We use bioinformatics, which is computational biology, and gene interactive and network analysis to evaluate the cancer tissue. And so at that point, we identified, and we asked the question, are there genetic differences between African Americans and European Americans? And what they found were driver genes, driver genes being the genes that drive the cancer, that make the cancers carry out a function, a mechanistic function, as opposed to passenger genes that are just associated with the cancer, just as in a car, the driver is the one that controls the car, the passenger sits there. These passenger genes, yes, they’re associated with aggressive cancer, but they have minimal or no function. The driver genes are the ones that are controlling the cancer, the function mechanism of the cancer progression. And so we identified in our analysis 21 genes that were different between African Americans compared to European Americans, different in terms of the expression of the disease, not different genes, but different expression of the genes.

What we found is that African Americans have a greater expression of inflammatory genes and transcript genes. And I’ll be more specific about that in a moment. Whereas European Americans had a higher expression of lipid metabolism genes. Those are genes that are associated with fatty acids as well as unsaturated fatty acids, specifically omega-6 as opposed to omega-3. But there is a connection between these two gene interactions at one particular molecule called tumor necrosis factor. And this gene then interacts with both the lipid metabolism genes as well as other inflammatory cytokines. And the genes that we found that were more specific in among the inflammatory genes were the pro-inflammatory cytokines, and those were IL-6 tumor necrosis factor, IL-8, and IL-1B as well as CXCR4.

These are what are called pro-inflammatory cytokines and chemokines. And they carry out functions that cause the cancers to invade. First of all, the cancer initial is cancer cells are stuck together. We call them adherent. They have to come apart before they can spread and go elsewhere. Well, these genes cause that it’s called epithelial mesenchymal transition. And once that happens, they’re capable of being transferred to distant sites such as the bone. And they also cause increased blood flow to the cancer. They also cause the oxidative stress that is driven by a molecule called reactive oxygen species.

And we’ll come back to that particular molecule because that’s important. Once it causes the oxidative stress, this causes DNA damaged repair genes to develop as well as mismatch genes. This mismatch means there are gene molecules that are stuck together, and there is an order. This order is upset by this particular oxidative stress, and those are mutated once they are repaired, and they impact on the mitochondria, which is a molecule in the cell nucleus that controls the chemistry of the cell.

And then this activates cancer stem cells, which is really important. And this is where we are going now with the cancer research. So TNF, the tumor necrosis factor IL-6 and IL-8, and the IL means interleukins. That’s what that stands for. They activate that pathway, the oxidative stress pathway. They also individually activate other pathways that lead to cancer stem cells. And I mentioned cancer stem cells because that’s the reason why chemotherapy and immunotherapy and all the drugs that we’ve used don’t work because the cancer stem cells undergo mutations and these mutations change the character of the cell. 

And that’s why the cancer cells resist that after a certain period of time, now these drugs will work and prolong survival, but they do not cure them because of the cancer stem cells. And so the cancer stem cells, in summary, are driven initially by the pro-inflammatory cytokines. So my research currently is to, well, how do we inhibit these pro-inflammatory cytokines? And that’s where we are now trying to develop a drug. We’re at the stage of mouse at this time, mouse biology and testing the drug in mice, not ready yet for human testing. So that’s where my research is headed, and I believe that that is going to work if the drug works.

Lisa Hatfield:

So just a follow-up question to that is, as a if I were a patient of yours or a family member, I might ask, so with your findings, do you think that this could lead to a cure, for example, for advanced prostate cancer?

Dr. Isaac Powell:

Yeah. I hate to use the word cure. The word I use is that we, our goal is to eliminate death from prostate cancer. That’s the term I prefer, because when we talk about cure, we have to know what causes it in order to really be certain as we are curing it. Because I don’t know whether what we’re doing is going to eliminate death, but that’s our goal. So I don’t like to use the word cure, because that’s the magic word and everybody gets excited. So I don’t want to get people excited too soon. So that’s where I am with my research.

Lisa Hatfield:

Well thank you so much for that. And do you have an activation tip for patients for this question, Dr. Powell?

Dr. Isaac Powell:

Yes. I think that, again, patients need to take charge by asking questions about the therapy. Again, is it going to cure me, and is the chemotherapy going to cure, immunotherapy going to cure? If not, how long do we think that I will live? That’s a good question, that I’d like to know if I were a patient. In fact, I’ve had prostate cancer and bladder cancer, so mine was early, so we didn’t get into those kinds of questions. But I like to know whether is this going to be something soon or later? Nobody can tell you when you may pass away from any cancer. I never give a patient any time. If they ask me, “Well, am I going to live six months or three years?” I don’t know. Because everybody’s different. Everybody responds differently to these particular treatments. So, but ask the questions as specific as possible that you’d like to know about the treatments, because there are several treatments, and there may be many answers.

We’re starting to hear more about BET inhibitors. Could you explain what they are and how they work to treat myelofibrosis? 

Dr. Lucia Masarova:

BET inhibitors are abbreviations for bromodomain inhibition, which is a very relevant regulator of transcription factors that play a significant role for making the blood cells.  

So, just differentiation of red cells or platelets, as well as very significant role in cytokines regulation. We know that myelofibrosis is a disease that is defined by overactive JAK-STAT Pathway that ultimately leads to increased cytokines.  

However, there are other pathways that play a significant role, and one of the very major ones is NF-kB, where the BET inhibitor come in play because they target it and help us to decrease the cytokine load as well as alter the differentiational block that happens in the red cells or megakaryocytes or platelets in these patients. 

So, the combination of bromodomain inhibition, or even using it as a single agent on or after refractory I think is a very promising tool that excludes the only JAK inhibition that we’ve been developing for diseases and opens the door for combination strategies that we were so many years thinking through and trying to find out. 

This is really the most promising compound or way of altering the disease background that we can see.

Katherine:   

Now, in reference to immunotherapy and CAR T-cell therapy, who are these types of treatments right for?

Dr. Patel:    

So, I think it’s really exciting that we finally are getting standard of care therapies for all these new immune therapies. So, our first CAR T for myeloma got approved a little over a year ago. Our second CAR T got approved just a couple of months ago, and we’re hoping our first bispecific will be approved in just a couple months.

Our fingers crossed. On the clinical trials, I will say our patients who had a good performance status, meaning they’re able to do everything else normally life-wise, those are the patients that got onto those clinical trials; and the reason is safety-wise.

So, T cells when we use them to kill myeloma, they release cytokines or enzymes, you can say, that are inside the T cells and that’s what they use to communicate with other immune cells to come help them kill.

Those are the same cytokines that make people feel really ill when they have the flu, for instance. So, as our immune system tries to fight infections when people get fevers, they feel chills, they feel just fatigued and tired, it’s those same kind of cytokines that, even when you try to kill the myeloma with T cells, people can get that same type of symptoms.

And really, the main, fevers and things like that, we can take care of. But when patients’ blood pressure drops or if their oxygen levels drop really low, that’s where we can run into some trouble. Now, the good news is, in myeloma, most of these new therapies don’t cause really bad CRS [Cytokine Release Syndrome] or really bad neurotoxicity that we can sometimes see. And so, thankfully most patients are okay, but really it’s making sure that none of our patients have bad toxicity. So, most of our myeloma patients, I will say, are eligible for these therapies. However, if someone has really bad heart disease or really bad lung disease, those are patients that maybe these are not the right therapies for.
