Ficerafusp alfa is directed against two targets, Epidermal Growth Factor Receptor (EGFR) and Transforming Growth Factor beta (TGF-β).
This study intends to evaluate the safety and efficacy of ficerafusp alfa in combination with pembrolizumab versus placebo with pembrolizumab in 1L PD-L1-positive, recurrent or metastatic Head and Neck Squamous Cell Carcinoma (HNSCC).
Age ≥18 years on the day the Informed Consent Form is signed.
Histologically or cytologically confirmed R or M HNSCC. Eligible primary tumor locations are oral cavity, hypopharynx, larynx or oropharynx (with documented HPV-negative disease if presenting with OPSCC). Note: primary tumor location of paranasal sinuses and nasopharynx, any histology are excluded.
No prior systemic therapy administered in the R or M setting; and completed systemic therapy >6 months prior if given as part of multimodal treatment for locoregionally advanced disease in the adjuvant or definitive setting.
Archival tumor tissue or willing to undergo pretreatment biopsy at Screening if archival tissue is insufficient or unavailable.
Disease suitable for local therapy administered with curative intent.
Prior treatment with anti-TGFβ therapy.
Prior therapy with an anti-EGFR antibody (exception: radio sensitizing agents and multimodal treatment for locoregionally advanced disease).
Prior history of Grade ≥2 intolerance or hypersensitivity reaction to anti-EGFR therapy or other murine proteins.
