Efficacy and Safety Study of Pembrolizumab (MK-3475) in Combination With Daratumumab in Participants With Relapsed Refractory Multiple Myeloma (MK-3475-668/KEYNOTE-668)
Withdrawn before enrolling · Phase 2
Conditions studied: Multiple Myeloma
In brief
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.

- Prior anti-myeloma treatments must have included an immunomodulatory drug (IMiD; i.e., lenalidomide, thalidomide, or pomalidomide) AND a proteasome inhibitor (PI; i.e., bortezomib, ixazomib, or carfilzomib) alone or in combination and participant must have failed therapy with an IMiD or PI or both.
- Has a performance status of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) Performance Scale.
- Has adequate organ function.
- Male participants must agree to use contraception during the treatment period and for at least 120 days after the last dose of study treatment and refrain from donating sperm during this period.
