Moreau discussed conclusions drawn from part 2 of the CASSIOPEIA trial and the need for further follow-up with bortezomib, thalidomide and dexamethasone plus maintenance daratumumab in newly diagnosed multiple myeloma.
At the 2021 American Society of Clinical Oncology (ASCO) Annual Meeting, CancerNetwork® sat down with Philippe Moreau, MD, of the University Hospital of Nantes, to discuss conclusions from part 2 of the phase 3 CASSIOPEIA trial (NCT02541383), which utilized daratumumab (Darzalex) maintenance therapy following treatment with bortezomib, thalidomide, and dexamethasone (VTd) in patients with newly diagnosed multiple myeloma. Moreau emphasized the need for a longer follow-up to validate these results.
We were able to update the results of part 1 [of the study]. The results are really clear from the first randomization with a very long follow-up now. Progression-free survival improved [in those who] received daratumumab up front during induction consolidation. [In order] to define the exact role of daratumumab in the maintenance setting, we need to have a long follow-up of the CASSIOPEIA trial, but also [for] the results of ongoing trials that are looking at daratumumab with lenalidomide [Revlimid; including] lenalidomide versus lenalidomide plus daratumumab. [It is possible that] the optimal strategy is the combination of daratumumab plus lenalidomide.
