Study Comparing Daratumumab, Lenalidomide, Bortezomib, and Dexamethasone (D-RVd) Versus Lenalidomide, Bortezomib, and Dexamethasone (RVd) in Subjects With Newly Diagnosed Multiple Myeloma

Janssen Research & Development, LLC224 enrolled

Overview

The purpose of this study is to determine if the addition of daratumumab to lenalidomide-bortezomib-dexamethasone (RVd) will increase the proportion of participants achieving stringent complete response (sCR), as defined by the International Myeloma Working Group (IMWG) criteria, by the time of completion of post autologous stem cell transplantation (ASCT) consolidation treatment, compared with RVd alone.
