A Trial of Pembrolizumab (MK-3475) in Participants With Blood Cancers (MK-3475-013/KEYNOTE-013)

NCT01953692 ↗

Phase 1 Completed 197 enrolled Merck Sharp & Dohme LLC
Non-randomizedParallel-groupOpen-labelTreatment

Summary

The purpose of this trial is to evaluate the safety, tolerability, and efficacy of pembrolizumab (MK-3475, KEYTRUDA®) and pembrolizumab in combination with lenalidomide (Cohort 5 only) in hematologic malignancies. The primary study hypotheses are that treatment with pembrolizumab will result in a clinically meaningful improvement in Objective Response Rate (ORR) or Complete Remission Rate (CRR). The study includes an initial dose determination to establish the recommended phase 2 dose (RP2D) of lenalidomide given in combination with pembrolizumab in Cohort 5. With Protocol Amendment 08, enrollment in the Multiple Myeloma arm (Cohort 2) has been completed and no further enrollment will be allowed and enrollment in the Non-Hodgkin Lymphoma Diffuse Large B Cell Lymphoma arm (Cohort 5) has been discontinued and no further enrollment will be allowed.
