Daratumumab wins new indication for newly diagnosed myeloma patients


Janssen’s daratumumab (Darzalex) has picked up a sixth adult multiple myeloma indication, this time in combination with lenalidomide (Revlimid) and dexamethasone in newly diagnosed patients ineligible for autologous stem cell transplants.

The phase 3 MAIA trial found that 97 of 368 patients (26.4%) treated with the combination – dubbed DRd – progressed or died at a median follow-up of 28 months, versus 143 of 269 (38.8%) treated with lenalidomide and dexamethasone alone (Rd). An estimated 55.6% of patients on lenalidomide and dexamethasone, versus 70.6% with the daratumumab add-on, were alive without progression at 30 months (N Engl J Med. 2019 May 30;380[22]:2104-15).

Previously approved indications for daratumumab include relapsed or refractory disease after at least one other therapy; and combination treatment with bortezomib, melphalan, and prednisone, also in newly diagnosed patients who are ineligible for transplant.

The most common grade 3 and 4 adverse events reported in the MAIA trial were neutropenia (50.0% for the DRd group versus 35.3% for the Rd group), anemia (11.8% vs. 19.7%), lymphopenia (15.1% vs. 10.7%), and pneumonia (13.7% vs. 7.9%).
