At EHA 2021, Shaji Kumar, MD, reviews the toxicity profile of daratumumab plus lenalidomide and dexamethasone for patients with transplant-ineligible multiple myeloma in the first-line setting.
CancerNetwork® sat down with Shaji Kumar, MD, of the Mayo Clinic, at the 2021 European Hematology Association (EHA) Congress to talk about long-term toxicities associated with daratumumab (Darzalex) plus lenalidomide (Revlimid) and dexamethasone in newly diagnosed multiple myeloma, and how there were no new safety signals detected at the 5-year follow-up to the phase 3 MAIA trial (NCT02252172).
Given the fact that daratumumab is a new drug, [the toxicity profile] is an area that everyone [questioned.] Are their long-term toxicities associated with this? Patients have been on therapy for long periods of time now [and] there were no new safety signals. There were no cumulative toxicities that were observed with daratumumab plus lenalidomide, and dexamethasone compared with lenalidomide/dexamethasone. There are certainly hematological toxicities that we saw before. There’s certainly more neutropenia with the [daratumumab] combination, and that is to be expected based on what we have seen before. [There’s] more lymphopenia as well, but nothing that appears to be new with the longer duration of therapy.
