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.

Katherine:

Personalized medicine for myeloma is slowly becoming more of a reality for patients. Can you provide an update in testing in myeloma? Are there specific markers that you’re looking for when considering patient care?

Dr. Nadeem:

So in multiple myeloma, right now the only targeted therapy that’s in development is looking at venetoclax (Venclexta), and that’s in patients that have the t(11;14) translocation.

So, this has been studied for a while, both as single agent and in combinations and the big BELLINI study, which is looking at it in combination with bortezomib (Velcade) and dexamethasone (Decadron), really has had a lot of buzz over the last few years because there was a toxicity signal with the venetoclax arm.

But now with, again, updated results, etcetera, you’re starting to look to see which are the patients that benefited and which are the patients that didn’t.

And it’s becoming very, very clear that patients that have the t(11;14) translocation tend to benefit tremendously with the combination of venetoclax and bortezomib and dexamethasone. It’s really the patients that don’t have t(11;14) or high BCL2 expression, which is something that they’re also studying, those are the patients that didn’t benefit.

So, really fine tuning that to that particular population and using a combination like that is, I think, an example of where things are headed in myeloma. However, outside of that right now with where things stand, we don’t have targeted therapy to that extent beyond that.

Katherine:

Dr. Nadeem, with the ASH meeting closing out 2021, what are you excited about in myeloma research right now?

Dr. Nadeem:

We’re seeing very impressive results with using quadruplet therapies for newly diagnosed multiple myeloma patents. So, they get a combination of a CD38 monoclonal antibody like daratumamab (Darzalex), and then combining it with our typical agents. So immunomodulatory, drugs, proteasome inhibitors, and steroids. So, an update at this meeting with the phase-2 GRIFFIN trial, which was presented by my colleague Dr. Jacob Laubach, basically giving an update after 24 months of maintenance therapy.

This trial looked at a combination of dara plus RVD, which is lenalidomide, bortezomib, and dexamethasone, with transplant and maintenance, for patients with newly diagnosed myeloma. And what we’ve seen with each update of this study, that the response rates with the quadruplets are significantly better with the triplet. And more notably, we’re seeing very high rates of minimal residual disease negativity in favor of the quadruplet, which usually translates into a greater prognosis for patients.

So, median PFS is still not reached for this particular study, but you can start to see now that the curves are starting to separate and hopefully with longer follow up, we’ll see even a clearer result showing that patients that receive a quadruplet therapy at the newly diagnosed phase of their myeloma therapy benefit tremendously. So, this was a really important update at ASH this year.

Notable News September 2019

September wraps up a big month of cancer awareness. It is the awareness month for childhood cancer, gynecologic cancer, leukemia and lymphoma, ovarian cancer, prostate cancer, and thyroid cancer. Awareness days bring people together to provide educational and fundraising opportunities, and they can help shine a brighter light on the need for funding and research. If you ordered anything from Amazon recently, you may have noticed just how impactful awareness months can be. During the month of September Amazon partnered with the American Childhood Cancer Organization (ACCO) and helped raise awareness by using special packaging designed with the childhood cancer gold ribbon symbol. That kind of exposure can lead to increased funding and support from those who might not otherwise be aware that every three minutes a child is diagnosed with cancer, and it remains the deadliest disease for children in the United States. Learn more at acco.org.
Like leukemia and lymphoma, multiple myeloma is a blood cancer, and while its awareness month is in March, this month there is some promising news for treating the incurable cancer, says biospace.com. The FDA approved the drug Darzalex to be used in combination with other medications for patients newly diagnosed and eligible for autologous stem cell transplant. Studies showed that adding Darzalex to the other medications reduced disease progression or death by 53 percent. More information about the uses of Darzalex can be found here.
Something else to be aware of this month is the potential danger of a popular heartburn medication, reports webmd.com. Ranitidine, known as Zantac, and several generic versions, may pose a cancer risk. The FDA found a cancer causing substance in the drug, and now at least one manufacturer has recalled the drug, and another one has stopped distributing it. It is not yet known why lab testing discovered a carcinogen in the drug, but if you take Zantac, or one of the generic versions, you should probably talk to your doctor, and read more about the findings here.
Of course, it would be ideal if we didn’t have to be aware of cancer at all anymore, and that just may be the case in the future, thanks to a “magic” treatment, says medicalxpress.com. Researchers, using a super computer, have found a molecule that could fix any cancer-related issues in the body. The molecule is promising because, unlike other immunotherapies, it could be sold in pill form, could reach deeper into tissues, and would leave the body faster, reducing negative side effects. Also, it could be used to fight several kinds of cancers including melanoma, breast cancer, lung cancer, lymphoma, and brain cancer. The magic pill still has further development, but the research is moving from the lab to animal testing, so fingers crossed that before long this magic molecule leads to a cure. You can find out more here.
September also hosts Take a Loved One to the Doctor Day, so mark your calendar for next year, and make sure you don’t miss any other important awareness dates. They can be found on the Patient Empowerment Network (PEN) Cancer Awareness Calendar, here.
