Efficacy, Safety, and Tolerability of Gebasaxturev (V937) Administered Intravenously or Intratumorally With Pembrolizumab (MK-3475) Versus Pembrolizumab Alone in Participants With Advanced/Metastatic Melanoma (V937-011)

Stopped early · Phase 2

Conditions studied: Advanced/Metastatic Melanoma

In brief

This is a Phase 2 study to assess the efficacy, safety, and tolerability of gebasaxturev 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 gebasaxturev 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. This study will be terminated once all participants finish treatment with V937. Participants eligible to continue to receive pembrolizumab will be transferred to MK-3475-587 study.
