Phase phase 1
Target PD-1
Sponsor Merck Sharp & Dohme Corp.
Start date February 2014
End date August 2017

This study will assess the efficacy and safety of pembrolizumab (MK-3475) administered to participants with incurable advanced biomarker-positive solid tumors that have not responded to current therapy or for which current therapy is not appropriate.

The study hypothesis is that administration of pembrolizumab to participants with some types of solid tumors will result in a clinically meaningful response rate.
