The Role of a Myeloma Specialist on Your Care Team

Transcript:

Katherine:

Let’s turn to decision-making, Dr. Khan. What is the role of the myeloma patient when making care and treatment decisions?  

Dr. Khan:

As a provider, my role is to inform the patient of the facts and the need for a decision. The purpose of the discussions is to determine the patient’s goals and preferences, because it’s essential the patient’s values of respected. The best outcomes occur when the medical facts align with the patient’s preferences. And this is a multi-disciplinary team approach.  

Katherine:

Why is it so important for patients to share any symptoms and side effects they’re having with their healthcare team?   

Dr. Khan:

I read something recently on an NIH website titled “What Do I Need To Tell the Doctor?” that I think answers this question well. And I’m quoting the article. “Talking about your health means sharing information about how you feel physically, emotionally, and mentally. Knowing how to describe your symptoms and bringing up other concerns will help you become a partner in your healthcare.”  

I think I really like that end, “partner in your healthcare.” The patient’s symptoms and suggest disease or disorder in the body. If there are concerns, this may prompt a clinic visit or the patient may be advised to go to the closest ER or urgent care depending on the urgency of the situation. But in other cases, the healthcare team may help provide reassurance that the symptom can be continued to be monitored more resolution, or it can be evaluated in more detail if it persists or worsens.  

Katherine:

What about side effects? Why is that important for patients to share any side effects they may be having?  

Dr. Khan:

Side effects may be a result of the disease itself. It might be a marker of the side effects from the treatment. Or I’m focused on the multiple myeloma, but there’s every other organ system in the body that also needs help. So, the myeloma might be doing okay. The treatment might be doing okay. But, for example, we might have a lung toxicity from their pre-existing COPD or a heart toxicity from their pre-existing coronary artery disease. So, it’s very important to share all symptoms So, we can see how to properly assess it.   

Katherine:

And better care for the patient.  

Dr. Khan:

Right.

Katherine:

Are there any recent advances in treatment for patients with relapsed or refractory disease?  

Dr. Khan:

Currently and in the past 20 years or so, we’ve seen about 20 approvals for new drugs for patients with multiple myeloma. The way the approval process works it typically looks at the effectiveness of a drug in the relapsed refractory setting first. And after establishing the safety and efficacy, the therapies are moved earlier in the disease course.   

The great example of this are the anti-CD38 monoclonal antibodies daratumumab and isatuximab. They were first approved in the relapsed refractory setting in combination with other antimyeloma treatments. And due to their impressive effectiveness and relative safety, they’re already being used in the frontline setting for patients with newly diagnosed multiple myeloma.   

In the newly diagnosed setting, a commonly cited study is the phase two GRIFFIN trial. And that added daratumumab to the BRd, or bendamustine (Bendeka, Treanda), lenalidomide (Revlimid), dexamethasone backbone.  

And Europe, they completed the phase three study of adding isatuximab, the other anti-CD38 monoclonal antibody to the BRd backbone. And what we’re finding what was very effective in the relapsed refractory setting was actually adding to the efficacy of newly diagnosed treatment regiments. As a side note, these trials – there are also trials looking at daratumumab and isatuximab in the smoldering myeloma phase, so moving it even earlier.  

I think one of the most attractive new targets in myeloma is targeting this antigen called B-cell maturing antigen, and a number of therapies are being developed or are already developed for it. The first approved was belantamab mafodotin, and this is an antibody drug conjugate. 

So, when the antibody binds to BCMA on the multiple myeloma cells, it releases its toxic payload into the myeloma cell. And so, it’s very effective towards myeloma, and no other good cells or fewer other good cells are affected by it. To provide some numbers, in patients with a median of seven prior lines of treatments, meaning their myeloma had relapsed that many times, the response rate was about 30 percent. And a fifth of those patients had VGPR, very good partial response, or better response.  

There are also bispecific antibodies that target this myeloma marker, and we anticipate getting one approved soon in the U.S. called teclistamab. Teclistamab is an antibody that binds both CD3 on T cells of the immune system and B-cell maturating BCMA on the myeloma cells. 

So, the way this antibody kills myeloma is by activating the T cells, the immune system, and directly killing the tumor. So, this was recently published in the New England Journal of Medicine. And in people who were treated with at least five prior lines of therapy, the response rate was about 63 percent, and the median progression-free survival, or the time until the myeloma progressed, was about 11 months.  

We were very active in a clinical trial looking at the effectiveness of another antibody, a bispecific antibody, called Regeneron 5458. In a similar patient population, the response rates were 75 percent in the higher-dose level group, and right now it’s actually a bit too early to tell how long the progression free survival is or the duration of response. 

There are also other bispecifics in development targeting other myeloma markers ssuch as talquetamab, that binds to a marker called GPRC5D, and cevostamab, which binds to a marker called FcRH5. The response rates as single agents in patients with relapsed refractory multiple myeloma are 66 percent and 45 percent respectively. These are all incredible numbers for a single drug in the relapsed refractory setting.

How does staging affect treatment option?  

Dr. Khan:

Staging is done by two methods. The older method is the international staging system, abbreviated as ISS. And then there’s the newer revised ISS, or RISS. 

The patients are assigned stages one to three. To determine the ISS you need lab values for the beta-2 microglobulin and albumin. For the revised ISS, you add on the lab value for LDH, lactate dehydrogenase, and you also add in the chromosome risk profile. So, there are certain genetic changes that predict a more aggressive myeloma. And the ones added to the revised ISS staging system are translocation 4;14, translocation 14;16, and deletion 17p.  

So, that’s the ISS stage and the revised ISS stage. There are also other factors patient providers look into when determining the risk profile for patients. So, that might include other genetic changes. 

One that is gaining a bit more traction right now is something called gain 1q, or amplification 1q, so more than one copy of part a chromosome. Some patients might have myeloma that doesn’t start, and the bone marrow might be found outside of the bones. And that’s called extramedullary disease, and sometimes that’s kind of high-risk. And some people have so much bone marrow plasma cells that it actually spills into their bloodstream. So, they might have high circulating plasma cells. Anyway, this will give information on staging.  

And in terms of how it affects treatment option, I’ll give maybe two examples. Let’s say in case one we have a 40-year-old patient high-risk multiple myeloma. The high risk portends a poorer prognosis, meaning the outcomes might not be as good as someone with a standard myeloma. So, in that case, I might try to do or use the most aggressive treatment option in order to maximize treatment responses because I know the overall outcome is poor. 

I do all this while acknowledging maybe the chances of having side effects might be higher, but that might be an acceptable tradeoff.  

In case two, I’ll flip to an 80-year-old with standard risk cytogenetics.  

So, I predict their myeloma to behave standard. In this case, I might try to use a regimen with a more acceptable safety profile, because the predicted response to treatment is anyways very good. So, I don’t want to hurt them in the process of getting their myeloma in remission.  

I’ll also say this. My practice pattern at The Ohio State University might be a little different than someone on the East Coast or West Coast, and that’s okay. We all have our experiences with the different treatment regimens, but we all have the same goal of being as aggressive as we can while being mindful of side effects. 

How Is CAR T-Cell Therapy Changing Myeloma Care?

Katherine:

Let’s talk about CAR T-cell therapy. How is CAR T-cell therapy changing the field?  

Dr. Khan:

Myeloma was a little late to the CAR-T game, but we’re very happy it’s here. The two products approved in myeloma are idecabtagene vicleucel, ide-cel for short, and ciltacabtagene autoleucel, or cilta-cel for short. 

So, the way CAR Ts work, they are customized T cells for each individual patient. You collect the T cell from the patient with myeloma. You reengineer them in the laboratory to produce proteins on their surface called chimeric antigen receptor. That’s CAR portion of the CAR T therapy. And these CARs recognize and bind specific proteins on the surface of multiple myeloma.  

So, these genetically modified T cells are then expanded or multiplied to make millions of cells. They’re sent back to the hospital where they were collected, where the patient is. And they’re infused back into the patient. The hope is that these modified cells, these CAR T cells, will continue to multiply in the patient. And with guidance from that engineered receptor, they will recognize and kill multiple myeloma very effectively. 

So, I can provide some numbers to the outcomes of the two approved CAR T cells – CAR T products in multiple myeloma. The first approved was ide-cel in patients with a median of six prior lines of therapy, a single dose of CAR T was able to produce an objective response rate – that’s how many people responded to the treatment – of 73 percent, and the median, the middle person, progressed after 8.8 months of getting this treatment. The other product, cilta-cel, was also studied in patients with a median of six prior lines of therapy, and the objective response rate was an astounding 98 percent.  

Katherine:

Wow.  

Dr. Khan:

And the median progression-free survival is actually not yet reached. So, these are remarkable results with heavily pre-treated myeloma. And the myeloma community’s very excited to actually bring these treatments to earlier lines of therapy such as a newly diagnosed patient with multiple myeloma.

Katherine:

Have there been advances in molecular testing for myeloma patients?  

Dr. Khan:

Molecular testing is a broad term and can indicate checking genes, proteins, and other molecules. Even let’s say speaking outside of the world of myeloma, molecular testing can be used to determine in individuals if they have a high chance of developing cancers or other diseases.  

It can be done to confirm so cancer diagnoses using the tissue biopsy specimens. It can also be used to help plan treatment, find out how well the treatment is working, provide prognosis information, and other information. In the world of myeloma, there are – in the world of myeloma, there are researchers looking at all of these molecular changes that can happen with disease.  

Katherine:

So, how do the results of these tests affect treatment?  

Dr. Khan:

There’s a particular cytogenetic change called translocation 11;14 that’s found in maybe a quarter of all patients with newly diagnosed myeloma, and it predicts a high likelihood of responding to a new drug called venetoclax.  

In the clinical trial of venetoclax, when it was given to all patients with multiple myeloma, there was actually higher mortality in patients when given venetoclax in combination with bortezomib and dexamethasone. And this is despite a higher response rate by adding the venetoclax.  

The thought process was maybe those patients were not doing well because of higher chances of serious infections. But when they took the data and they looked at that subgroup of patients with the translocation 11;14, there was no such concern in that subgroup. So, in this case of having translocation 11;14, it actually giving you a new treatment option based on the findings of the molecular testing. 

We participate in a national clinical trial called MyDRUG, and that’s looking at other molecular changes to see if a more targeted treatment when added to the backbone of myeloma therapies translates to better outcomes.  

Another recent development in molecular testing is diagnostic testing for minimal residual disease, and that’s from the bone marrow in patients with multiple myeloma.  

The most commonly used test in clinical trials is the clonoSEQ test; it’s an FDA-cleared diagnostic test. The way it works it looks for specific DNA sequences on the receptors of the cancer cells. So, each cancer cell has like a genetic barcode.  

Using the liquid part of the marrow, we can look for those cells that harbor that genetic barcode. 

And the test is so sensitive, we can find one in a million cells in a patient’s bone marrow aspirate. So, it’s a very sensitive test, but it is not yet approved for making treatment decisions. One way we can use it though is for prognostic information. So, a patient attaining minimal residual disease-negative status or MRD-negativity, probably will do better than someone who has MRD-positive disease.  

And there’s an emerging concept called sustained MRD negativity. So, let’s take an example of someone getting MRD testing at one year and two years after their stem cell transplant. The patient who is MRD-negative at both the one-year and two-year marks will likely do better than the one who is MRD-negative at one year but turns positive at the two-year mark. 

So, these are some of the new developments in molecular testing in multiple myeloma.

Katherine:

What testing should take place before choosing a myeloma treatment?  

Dr. Khan:

I thought I could answer this question in an indirect way first.  

Katherine:

Okay.  

Dr. Khan:

I just wanted to let the audience know that anyone, including those that are not in the medical field, can create an account with the nccn.org. That’s the National Comprehensive Cancer Network’s website.  

And from there they can download the myeloma guidelines, which are available to all myeloma providers as well. And in the guidelines, there are sections for workup, treatment, how to follow patients with myeloma, and many other things.   

So, going back to the question, the first patient encounter will likely include a thorough history and physical exam. Initial lab work includes blood counts, the serum chemistries so we know about the liver and kidney function, multiple myeloma markers. And patients about get very familiar with monoclonal protein, the serum immunoglobulins, and the serum-free light chains. 

These are used as the surrogates for responses when you’re undergoing treatment for the myeloma. We will also at the first visit probably also do a 24-hour urine collection, and that’s looking for the abnormal protein in the urine.  

There’s imaging. In the past, we used to do x-rays head to toe. That’s sometimes called the myeloma survey or the skeletal survey. But the new recommendations are actually looking for something a bit more sensitive.  

So, at our practice, what we do is a PET scan.  

So, that includes functional information as well the images themselves. And some institutions may do a PET scan head to toe using low-dose radiation. The final test we will do in patients with newly diagnosed myeloma is a bone marrow biopsy and an aspirate. 

So, the biopsy’s looking at the bone itself and the architecture. And the aspirate, you take the liquid part of the bone marrow, and you can ascertain a lot of information including the burden of myeloma when the patient’s newly diagnosed.  

Katherine:

What do you mean by “burden”?   

Dr. Khan:

You can quantify the number of cancerous plasma cells in the bone marrow. So, some of the information says you have a healthy amount of good bone marrow cells, 50 percent, 60 percent, for example, but of that 50 percent, 60 percent, maybe 80 percent is taken over by myeloma. So, you will get burden of myeloma information from there.  

Katherine:

What additional testing should take place following a relapse?  

Dr. Khan:

I’ll start that response by first talking about the types of relapses, and there are two broad categories. If we see the myeloma coming back as just the monoclonal protein going back up from its lowest, or maybe the serum-free light chain going up – and there are very specific criteria for what defiance a relapse. But if it’s just a number, we call it a biochemical relapse.  

On the other side, there’s a clinical relapse. And at that point, there might be new end organ damage. We’ve heard of the acronym CRAB when we’re describing myeloma. That stands for hypercalcemia, renal or kidney insufficiency, anemia, and bone disease. So, these are end organ damage directly from the multiple myeloma. 

So, typically, we’ll try to change the management at biochemical relapse, because a new organ injury may contribute to the patient’s frailty, or it might even limit the treatment options. The testing out of relapse is pretty similar to the first diagnosis. We’ll repeat the history and the physical example, the labs, imaging. And more often than not, I’ll also recommend a bone marrow biopsy to see is that myeloma changing genetically, and does it help me kind of determine new treatment options.

The Benefits of Participating in a Myeloma Clinical Trial


Transcript:

Katherine:

What would you say to someone who’s hesitant in participating in a trial?  

Dr. Khan:

Well, the decision to participate is complex and personal, but the ultimate decision regarding trial participation rests with the patient. So, some of the reasons why patients might be hesitant, they might have distrust toward the medical community given the history of clinical trials in this country. If we take the example of the abuse of African American patients during the Tuskegee syphilis experiments, that’s just one example.  

Katherine:

Yeah.  

Dr. Khan:

Another reason patients might be hesitant is they don’t like the idea of being randomized to the treatment that they’re going to get. 

So, they might end up getting a placebo. They might get another standard of care. And they might not get that new, fancy drug. So, giving up that level of control does require some compromise. Another reason is the uncertainty of the potential side effects of the chemotherapy drugs, especially if you’re participating in an early-phase clinical trial.  

Furthermore, trials require very defined and frequent monitoring sometimes. So, some patients might not like the time commitment to a clinical trial. Another reason might be that there are concerns for cost. I can alleviate that concern by saying that typically there are mandates that the insurer cover the routine costs of clinical trials.  

Katherine:

You mentioned some misconceptions. Are there any others that patients might have about participating in a trial? 

Dr. Khan:

I guess the two most common things, the first one, and I think all providers have heard this, “I will be treated like a guinea pig.”  

Katherine:

Yeah.   

Dr. Khan:

For me, that is probably the furthest from the truth because of all the safeguards in place. Clinical trial participants are followed the most closely and probably get more medical attention than someone who is not on clinical trial. To participate in the clinical trial, the participant has to voluntarily – and that’s the keyword – sign an informed consent form. And finally, the participant can also leave the trial at any time for any reason.   

Another common misconception is that clinical trials of dangerous because they use untested drugs. There might be some truth to that. There are many phases to clinical trials. And in some early-phase clinical trials it is true that participant may actually be the first to ever get the new therapy. 

So, some of the outcomes are not known. But in late-phrase clinical trials, tens to thousands of patients may have already been treated with the study drug, so there a lot of preliminary safety data and also efficacy data.

Transcript:

Katherine:

I’d like to turn to clinical trials now. Why should a myeloma patient consider participating in a clinical trial?  

Dr. Khan:

The main potential benefit to a patient includes getting a new treatment for a disease before it’s even approved for other patient with multiple myeloma. Sure, clinical trials have risks and benefits, but participating in a clinical trial is probably also safer than ever.  

What I mean by that is clinicians that participate in clinical trials are required to follow very strict rules and guidelines to make sure the participants are safe, and these rules are enforced by the federal government. Each clinical trial also follows a careful study plan, or protocol, and that describes what researchers will do and when they will do it. 

And the principal investigator, or the lead researcher, for that clinical trial has the responsibility that the protocol is followed at every site that the study is available. So, generally, that also means participants will get more frequent health checkups as being part of the clinical trial. And by volunteering for a clinical trial, patients are helping themselves and also the general society for patients afflicted with multiple myeloma.  

Katherine:

Right. Everyone who comes after them would be impacted. Why is patient participation in myeloma clinical trials critical to advancing research?  

Dr. Khan:

Clinical trials help researchers better understand health and disease. Clinical trial participation is actually considered the gold standard of providing medical healthcare.  

And, in fact, every therapy that is currently approved for myeloma right now is a direct consequence of participation of brave volunteers.
