carcinoma (R/M HSNSCC) incurable by local therapies, expressing PD-L1 with a combined
proportion score (CPS) ≥20.

Prior systemic therapy completed >6 months prior to signing informed consent is allowed if given as part of multimodal treatment for locoregionally advanced disease with curative intent, and no PD/recurrence occurred within 6 months of its completion. Prior systemic immunotherapy in the locoregionally advanced disease with curative intent, including but not limited to anti-PD-(L)1 agents, is allowed if PD/recurrence occurred ≥12 months after its completion.
Has clinically active central nervous system metastases and/or carcinomatous meningitis.
Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of study treatment.
