OUTLINE: Patients are randomized to 1 of 3 arms.
ARM I: Patients receive binimetinib orally (PO) twice daily (BID) for a lead-in period of 15 days in the absence of disease progression or unacceptable toxicity. Patients then receive binimetinib PO BID on days 1-28 and avelumab intravenously (IV) over 60 minutes every 2 weeks. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
ARM II: Patients receive anti-OX40 antibody PF-04518600 IV over 60 minutes for a for lead-in period of 15 days in the absence of disease progression or unacceptable toxicity. Patients then receive anti-OX40 antibody PF-04518600 IV over 60 minutes and avelumab IV over 60 minutes every 2 weeks. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
ARM III: Patients receive utomilumab IV over 60 minutes for a lead-in period of 15 days in the absence of disease progression or unacceptable toxicity. Patients then receive utomilumab IV over 60 minutes every 4 weeks and avelumab IV over 60 minutes every 2 weeks. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days, then every 6 months for a minimum of 1 year.
