Exclusion Criteria:

The main exclusion criteria include but are not limited to the following:

• Has clinically significant cardiovascular disease

• Bullous exfoliative skin disorders of any grade

• Known hypersensitivity to MK-0472 or pembrolizumab, or any of their excipients

• Received therapy with a proton-pump inhibitor or an H2 histamine blocker receptor antagonist within 7 days before the first scheduled day of study dosing

• Has discontinued prior therapy with an anti-programmed cell death-1 (PD-1), anti-programmed death-ligand 1 (PD-L1), or anti-programmed death-ligand 2 (PD-L2) agent or with an agent directed to another stimulatory or coinhibitory T-cell receptor due to an adverse event

Participants with previously treated brain metastases may participate provided they are radiologically stable for at least 4 weeks as confirmed by repeat imaging performed during the study screening, are clinically stable and have not required steroid treatment for at least 14 days before the first dose of study intervention

• Has active autoimmune disease that has required systemic treatment in the past 2 years except replacement therapy

• Has history of pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease

• Has active infection requiring systemic therapy
