Amivantamab Subcutaneous Formulation Shows 45% ORR in Recurrent/Metastatic Head and Neck Cancer
Johnson & Johnson presented promising Phase 1b/2 OrigAMI-4 data at ESMO 2025 on subcutaneous amivantamab for recurrent/metastatic HPV-unrelated head and neck squamous cell carcinoma (R/M HNSCC) after checkpoint inhibitor and platinum therapy failure. The study showed a 45% overall response rate and tumor shrinkage in 82% of patients, surpassing current therapy benchmarks. SC delivery allows for rapid injection, reducing clinic time. The ongoing Phase 3 OrigAMI-5 study will evaluate amivantamab with pembrolizumab and carboplatin as a first-line treatment.
