Intervention(s)

Crossover Period:
-Arm A: MK-3475A subcutaneous (SC) every 3 weeks (Q3W) for 3 cycles followed by pembrolizumab intravenous (IV) Q3W for 3 cycles

- Has a life expectancy of at least 3 months.
- Human immunodeficiency virus (HIV)-infected participants must have well controlled HIV on antiretroviral therapy (ART).
- Participants who are hepatitis B surface antigen (HBsAg) positive are eligible if they have received hepatitis B virus (HBV) antiviral therapy for at least 4 weeks, and have undetectable HBV viral load before randomization.
- Participants with history of hepatitis C virus (HCV) infection are eligible if have completed curative antiviral therapy at least 4 weeks before randomization and HCV viral load is undetectable at screening.
- Has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1 assessed within 3 days before the start of study intervention.

Exclude criteria

- Melanoma participants with ocular, mucosal, or conjunctival melanoma.
- Renal Cell Carcinoma (RCC) participants who have had major surgery, other than nephrectomy, within 12 weeks before randomization.
- Has received prior radiotherapy for RCC.
- RCC participants who have residual thrombus post nephrectomy in the vena renalis or vena cava.
- Has received prior therapy with an anti-programmed cell death 1 protein (PD-1), PD-L1, or anti-PD-L2 agent, or with an agent directed to another stimulatory or coinhibitory T-cell receptor (eg, cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), OX-40, CD137).
