Bicara Therapeutics reported three-year follow-up data from its Phase 1/1b study of ficerafusp alfa plus pembrolizumab in first-line HPV-negative recurrent/metastatic head and neck squamous cell carcinoma. At the pivotal 1500mg weekly dose, the combination showed an estimated 31% overall survival at three years, approximately doubling survival versus a retrospective standard-of-care pembrolizumab analysis.
Across 750mg weekly, 1500mg weekly and 2000mg every-other-week cohorts, confirmed response rates ranged from 48–57%, with complete response rates of 13%, 25% and 30% as of March 31, 2026. Deep responses of at least 80% tumor shrinkage were common at higher doses and were associated with longer duration of response, progression-free survival and overall survival. Bicara highlighted biomarker data supporting TGF-β inhibition as the driver of these deep, durable responses and noted that the pivotal FORTIFI-HN01 Phase 2/3 study and an alternate dosing study are ongoing or planned.
