Multiple Myeloma Clinical Trial

Efficacy and Safety Study of Pembrolizumab (MK-3475) in Combination With Daratumumab in Participants With Relapsed Refractory Multiple Myeloma (MK-3475-668/KEYNOTE-668)

Summary

The purpose of this study is to assess the efficacy and safety of pembrolizumab (MK-3475) in combination with daratumumab in participants with relapsed refractory multiple myeloma (rrMM). The primary outcome measure for this study is the assessment of Objective Response Rate (ORR) in participants with rrMM.
