Event-free Survival (EFS) in MATTERHORN: A Randomized, Phase 3 Study of Durvalumab plus 5-Fluorouracil, Leucovorin, Oxaliplatin and Docetaxel Chemotherapy (FLOT) in Resectable Gastric/Gastroesophageal Junction Cancer (GC/GEJC)

Presented by Yelena Y. Janjigian at ASCO 2025, the Phase 3 MATTERHORN study demonstrated that adding durvalumab to FLOT significantly improved event-free survival compared with FLOT alone in patients with resectable gastric and gastroesophageal junction adenocarcinoma, with consistent benefit across subgroups and no new safety concerns.
