Surgically Treated Adjuvant Merkel cell Carcinoma with Pembrolizumab, a Phase III Trial (STAMP)

General Information Age Group Adults Status Recruiting Protocol Number NCT03712605 Background Information This study is being done to determine if the chance of cancer growing back is lessened by adding a study drug after surgery. This study may help discover if this approach is better or worse than the usual approach for Merkel Cell Carcinoma. The usual approach is defined as care most people get after surgery to remove cancer. The usual approach for patients who are not in a study is treatment with surgery, followed by close observation and sometimes radiation. A doctor can explain which treatment may be best. These treatments can reduce symptoms and may stop the tumor from growing for a few months or longer. This study has public funding from the National Cancer Institute (NCI), part of the National Institutes of Health (NIH) in the United States Department of Health and Human Services.
