A matching-adjusted indirect treatment comparison (MAIC) of daratumumab-bortezomib-melphalan-prednisone (D-VMP) versus lenalidomide-dexamethasone continuous (Rd continuous), lenalidomide-dexamethasone 18 months (Rd 18), and melphalan-prednisone-thalidomide (MPT).

D-VMP is a novel treatment for transplant-ineligible newly diagnosed multiple myeloma (TIE NDMM). D-VMP significantly prolonged PFS versus VMP in the ALCYONE trial. The FIRST trial investigated Rd given in 28-day cycles until disease progression, Rd for 18 cycles, and MPT for 12 cycles for TIE NDMM. As no randomized controlled trials comparing D-VMP to standard-of-care regimens such as those in FIRST are available, an MAIC was performed to assess relative OS and PFS for D-VMP from ALYCONE and Rd continuous, Rd 18, and MPT from FIRST. Individual patient data for D-VMP in ALCYONE were weighted to match aggregated baseline patient characteristics for each arm of FIRST. D-VMP significantly improved OS versus MPT and Rd 18, with a trend favoring D-VMP versus Rd continuous. D-VMP performed significantly better than all FIRST comparators for PFS. This MAIC demonstrates OS and PFS benefits for D-VMP versus Rd continuous, Rd 18, and MPT.
