(Nasdaq: BCAX), a clinical-stage biopharmaceutical company committed to bringing transformative bifunctional therapies to patients with solid tumors, today presented preliminary data from a Phase 1b expansion cohort evaluating 750 mg of ficerafusp alfa weekly (QW) in combination with pembrolizumab in first-line (1L) human papillomavirus (HPV)-negative recurrent/metastatic (R/M) head and neck squamous cell carcinoma (HNSCC). The data were highlighted in an oral presentation by Deborah Wong, MD, PhD of UCLA Medical Center at the European Society for Medical Oncology (ESMO) Asia Congress and will be discussed on a company conference call and webcast today, December 6, at 9:00 a.m. ET. “Inadequate tumor penetration remains a major barrier in treating solid tumors such as R/M HNSCC,” said Claire Mazumdar, PhD, MBA, Chief Executive Officer of Bicara Therapeutics. “Ficerafusp alfa, the first and only bifunctional EGFR-directed antibody x TGF-β ligand trap, was purposefully designed to deliver deep and durable responses with the potential to meaningfully extend overall survival for patients. The data presented today mark an important advancement in our dose-optimization strategy, reinforce our confidence in the interim overall response rate analysis as the foundation for pursuing accelerated approval in the FORTIFI-HN01 pivotal trial, and further elucidate the relative contribution of TGF- β in driving deep and durable tumor responses. We have made significant progress in the FORTIFI-HN01 trial this year and are on track to declare an optimal dose in the first quarter of 2026.” Phase 1/1b expansion cohort data presented at ESMO Asia show that 750mg ficerafusp alfa in combination with pembrolizumab was generally well-tolerated, with a safe...
