Showed two immunotherapy options for squamous oesophageal cancer, including one with no chemotherapy at all, both extending survival.
CheckMate 648, trial NCT03143153 sponsored by Bristol Myers Squibb and reported in 2021, showed two immunotherapy options for first-line advanced oesophageal squamous cell carcinoma, nivolumab plus chemotherapy and a chemotherapy-free doublet of nivolumab plus ipilimumab, both extending survival. It randomised 970 patients across three arms and met its primary overall survival endpoint in PD-L1-positive patients for both regimens, with benefit in all randomised patients and durable separation confirmed at five-year follow-up in 2026, leading to FDA approval of both regimens in May 2022. OnCo links it to oesophageal cancer, PD-1 and CTLA-4 as targets, nivolumab, ipilimumab and Jaffer A. Ajani. Which patients are best served by avoiding chemotherapy altogether is the open question.
