MK-3475 Trial for Colorectal Cancer

Study of Pembrolizumab (MK-3475) as Monotherapy in Participants With Previously-Treated Locally Advanced Unresectable or Metastatic Colorectal Cancer (MK-3475-164/KEYNOTE-164)

In this study, participants with previously-treated locally advanced unresectable or metastatic microsatellite-instability high colorectal carcinoma (MSI-H CRC) will be treated with pembrolizumab (MK-3475) monotherapy. The primary study hypothesis is that pembrolizumab will provide a clinically meaningful overall response.

Study of Pembrolizumab (MK-3475) vs Standard Therapy in Participants With Microsatellite Instability-High (MSI-H) or Mismatch Repair Deficient (dMMR) Stage IV Colorectal Carcinoma (MK-3475-177/KEYNOTE-177)

In this study, participants with MSI-H or dMMR advanced colorectal carcinoma will be randomly assigned to receive either pembrolizumab or the Investigator's choice of 1 of 6 standard of care (SOC) chemotherapy regimens for the treatment of advanced colorectal carcinoma. The primary study hypothesis is that pembrolizumab will prolong progression-free survival (PFS) compared to current SOC chemotherapy.
