Official title
A Single-Arm Pilot Study of Adjuvant Pembrolizumab in Patients With MSI-H Tumors With Persistent Circulating Tumor DNA Following Surgery
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to test the safety of the study drug, pembrolizumab, and to find out how well it works to prevent cancer from coming back in people who have had a solid tumor surgically removed, but still have tumor cells in their blood. During the study, the participant will receive either the study drug or a placebo for as long as 12 months, or until the cancer comes back, or the side effects of the treatment become too severe.
