Official title

A Phase 1b/2 Clinical Study of Intratumoral Administration of V937 in Combination With Pembrolizumab (MK-3475) in Participants With Advanced/Metastatic Solid Tumors

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to evaluate the safety, tolerability, and efficacy in participants with advanced/metastatic or recurrent malignancies who receive gebasaxturev (V937) in combination with pembrolizumab (MK-3475). The primary objective for Part 1 is to evaluate the objective response rate, and the primary objective for Part 2 is to determine the safety and tolerability of gebasaxturev administered in combination with pembrolizumab. With Amendment 4, this study will be terminated once all participants who have completed or discontinued gebasaxturev treatment and are only receiving pembrolizumab may be enrolled in a pembrolizumab extension study, if available, to continue pembrolizumab monotherapy for up to 35 cycles from first pembrolizumab dose on V937-013.
