For people with stage IV microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) colon and rectal cancer

Study of Pembrolizumab vs Standard Therapy in Participants With Microsatellite Instability-High or Mismatch Repair Deficient Stage IV Colorectal Carcinoma

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) or overall survival (OS) compared to current SOC chemotherapy.

Status:

Active, not recruiting

Phase 3 Icon

Trial Phase

The investigational immunotherapy is being studied in a large group of patients to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the investigational immunotherapy to be used safely.

Eligibility

About the Trial

All patients who enroll in the trial will receive medication while on the study.

  • 50% will receive pembrolizumab
  • 50% will receive treatment of study doctor’s choice (FOLFOX6, FOLFIRI, FOLFOX 6 + bevacizumab, FOLFOX 6 + cetuximab, FOLFIRI + bevacizumab, or FOLFIRI + cetuximab)

You will be assigned by chance (a process called randomization) to receive one of the above treatments.
