Efficacy, Safety, and Tolerability of V937 Administered Intravenously or Intratumorally With Pembrolizumab Versus Pembrolizumab Alone in Participants With Advanced/Metastatic Melanoma

This is a Phase 2 study to assess the efficacy, safety, and tolerability of V937 administered both intratumorally (ITu) and intravenously (IV) as combination therapy with pembrolizumab (MK-3475) versus pembrolizumab alone in anti-programmed cell death ligand 1 (anti-PD-L1)-treatment-naive participants with advanced/metastatic melanoma. The primary hypothesis of the study is that V937 administered either ITu or IV in combination with pembrolizumab results in a superior objective response rate (ORR) per Response Evaluation Criteria In Solid Tumors Version 1.1 (RECIST 1.1) based on blinded independent central review (BICR), compared to pembrolizumab alone.
