Stage III Merkel Cell Carcinoma AJCC v8 Clinical Trial
Official title:
A Multicenter, Randomized, Double-Blinded, Placebo-Controlled, Phase 3 Trial of Adjuvant Avelumab (Anti-PDL-1 Antibody) in Merkel Cell Carcinoma Patients With Lymph Node Metastases
This randomized phase III trial studies how well avelumab works in treating patients with Merkel cell cancer that has spread to the lymph nodes and have undergone surgery and/or radiation therapy. Immunotherapy with monoclonal antibodies, such as avelumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients receive avelumab intravenously (IV) over 1 hour once every 15 days for the first 120 days (Induction Phase 1), once every 30 days for the next 120 days (Induction Phase 2), and then once every 120 days (Maintenance Phase) for a maximum of 720 days (approximately 24 months or 2 years total) in the absence of disease progression or unacceptable toxicity. ARM II: Patients receive placebo IV over 1 hour once every 15 days for the first 120 days (Induction Phase 1), once every 30 days for the next 120 days (Induction Phase 2), and then once every 120 days (Maintenance Phase) for a maximum of 720 days (approximately 24 months or 2 years total) in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 6 months for 5 years from day 1 and then once every 12 months until the study is terminated by the sponsor. ;
