Background

PD-L1 is expressed on MM plasma cells and has been associated with higher MM cell proliferation. Thus, PD-L1 blockade with pembrolizumab may act synergistically with immunomodulatory drugs to enhance MM tumor suppression. In the phase 1 KEYNOTE-023 study, pembrolizumab + lenalidomide and low-dose dexamethasone showed an acceptable safety profile and promising preliminary efficacy in patients with relapsed/refractory MM, supporting further evaluation of this treatment combination. The randomized, open-label, phase 3 KEYNOTE-185 study (ClinicalTrials.gov, NCT02579863) was designed to compare the efficacy and safety of lenalidomide and low-dose dexamethasone (standard of care) with or without pembrolizumab in patients with newly diagnosed and treatment-naive MM.

Trial design

Key eligibility criteria include age ≥18 years, newly diagnosed, treatment-naive, active MM with measurable disease, and ineligibility for autologous stem cell transplantation. Patients will be randomized 1:1 to receive lenalidomide 25 mg daily on days 1-21 and low-dose dexamethasone 40 mg on days 1, 8, 15, and 22 of repeated 28-day cycles, with or without pembrolizumab 200 mg every 3 weeks. Patients will be stratified based on age (
