Bortezomib, melphalan, and prednisone (VMP) is the standard of care for transplant-ineligible newly diagnosed multiple myeloma. The phase III VISTA trial established the bortezomib dosing schedule for VMP. To mitigate bortezomib-associated toxicity, the phase III ALCYONE study of daratumumab plus VMP (D-VMP) versus VMP used modified bortezomib dosing. D-VMP demonstrated improved progression-free survival and overall response rate. Propensity score matching enables indirect comparisons by controlling for differences in baseline covariates.


The efficacy and safety of both arms of ALCYONE were compared with VISTA VMP using propensity score matching. ALCYONE D-VMP and VMP patients were matched on selected baseline characteristics to VISTA VMP patients, reducing or eliminating systematic differences between treatment groups.


After matching, median progression-free survival and overall response rate were comparable for ALCYONE VMP and VISTA VMP, and were significantly improved with ALCYONE D-VMP versus VISTA VMP. Rates of grade 3/4 peripheral sensory neuropathy were significantly lower for both arms of ALCYONE versus VISTA VMP, with or without matching.


This propensity score matching analysis demonstrates significant improvements in efficacy with ALCYONE D-VMP versus VISTA VMP and a significantly lower incidence of peripheral sensory neuropathy in both arms of ALCYONE versus VISTA VMP, although safety improvements may be due to different bortezomib administration routes (ALCYONE, subcutaneous; VISTA, intravenous).
