No currently present metastases (as confirmed by standard imaging studies (e.g. suggested by S2k guidelines). 5. No previous systemic therapy for MCC. 6. Required values for initial laboratory tests: · WBC ≥ 2000/uL · ANC ≥ 1000/uL · Platelets ≥ 75 x 103 /uL ·Hemoglobin ≥ 8 g/dL (≥ 80 g/L) · Creatinine ≤ 2.0 x ULN · AST/ALT ≤ 2.5 x ULN ·Total Bilirubin ≤ 2.0 x ULN (except patients with Gilbert’s Syndrome, who must have a total bilirubin less than 3.0 mg/dL) 7.

Any non-oncology vaccine therapy for up to 1 month before or after any dose of nivolumab. 6. A history of prior or current treatment with a T cell potentiating agent (e.g. IL-2, interferon, anti-CTLA-4, anti-CD137, anti-PD1, anti-PD-L1, or anti-OX40 antibody). 7. Chronic use of immunosuppressive agents or systemic corticosteroids. 8.
