The expert panel

Joshua Richter, MD, led an enthusiastic panel with his colleagues in the multiple myeloma space during a 2 Minute Drill program following the 2023 American Society of Hematology (ASH) Annual Meeting and Exposition. Richter, associate professor of medicine in The Tisch Cancer Institute, Division of Hematology and Medical Oncology at Mount Sinai, set the groundwork at the beginning of the program, letting his colleagues know that they could offer any unbiased thoughts and opinions from the recent meeting.

He was joined by Beth Faiman, PhD, CNP, a hematologic oncologist from the Cleveland Clinic; Jeffrey V. Matous, MD, Member Physician at the Colorado Blood Cancer Institute and part of the Plasma Cell Disease Group; and Saad Z. Usmani, MD, MBA, FACP, chief od the Myeloma Service at Memorial Sloan Kettering Cancer Center.

With the guidelines set, and bragging encouraged, the panel set off to discuss the most anticipated data from the recent ASH 2023.

Matous on the Biggest Surprise to Come From ASH

"I’m going to go old school here. I’m going to go with the abstract presented by Nizar Jacques Bahlis, MD, bringing venetoclax [Venclexta] back into the forefront of multiple myeloma treatment.1 I had [often] overlooked venetoclax in patients with t(11;14) myeloma and just gone with more traditional therapies. Bahlis presented data comparing venetoclax with daratumumab [Darzalex]/dexamethasone vs daratumumab/dexamethasone and bortezomib [Velcade], and the overall response rate for the venetoclax arm was 96%. The minimal residual disease negativity occurred in about 40% of patients there. The responses were durable and there were no unusual safety signals that came out of there. So, for me, it’s like bopping me over the head and saying, 'Hey, buddy, when you see t(11;14), you have got to think about venetoclax.'

Faiman on the Most Practice-Changing Trial

I think it’s the phase 3 IsKia trial [NCT04483739]. I like the idea of the [4-drug regimen], especially for patients who are high risk with myeloma.2 That’s Francesca Gay, MD, PhD, and her group who led this trial with carfilzomib [Kyprolis], lenalidomide [Revlimid], dexamethasone and then transplant, and then multiple…arms of randomization. Now we’re adding isatuximab [Sarclisa] to these patients, and especially for those patients with high-risk disease, it makes a difference. One of the drawbacks that I don’t love about this study, though, is a lot of dexamethasone and [lack of] long-term follow-up. However, I feel that especially for patients who are high risk, even though this is going to need a longer-term follow-up, it might reflect a new practice-changing thing. The reason I didn’t cite the phase 3 PERSEUS [NCT03710603] trial is not only does it use dexamethasone at 40 mg on days 1 through 4 and 9 through 12, which is a ridiculous amount of dexamethasone, the PERSEUS study uses daratumumab and VRd [bortezomib, lenalidomide, dexamethasone] and we’re already using that induction based on the GRIFFIN trial’s phase 2 data [NCT02874742].3,4 For me again, it’s the IsKia trial. With the late-breaking abstract PERSEUS, I think a lot of individuals and myeloma providers are already using that."

Usmani on the Next Trial Leading to an FDA Approval

"The big phase 3 trends that read out are KarMMa-3 [NCT03651128] and CARTITUDE-4 [NCT04181827] this year, where the major highlight all of us are holding our breaths to see if those FDA approvals will come through.5,6 There were several highlighted abstracts, including the KarMMa-3 update from Paula Rodriguez Otero, MD, PhD, which will be the most impactful abstracts and will lead to the quickest FDA approvals in the earlier-line setting."

WINNERS

Beth Faiman, PhD, CNP

“The excitement is real and the energy is palpable. Hopefully we'll continue to keep on searching for the cure together.”

Saad Z. Usmani, MD, MBA, FACP

“The future is bright, and the cure is near.”
