STAMP: Surgically Treated Adjuvant Merkel cell carcinoma with Pembrolizumab, a Phase III Trial.
This phase III trial studies how well pembrolizumab works compared to standard of care observation in treating patients with stage I-III Merkel cell cancer that has been completely removed by surgery (resected). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
• Patient must have a histological confirmation of diagnosis of Merkel cell carcinoma (MCC), pathologic stages (American Joint Committee on Cancer [AJCC] version 8) I-IIIb.
• Patients with all macroscopic Merkel cell carcinoma (either identified by physical exam or imaging) have been completely resected by surgery within 16 weeks before registration.
• All patients must have disease-free status documented by a complete physical examination and conventional imaging studies within 8 weeks prior to registration.
• Patient may not have a history of distant metastatic disease.
