Triple-Drug Regimen with Tiragolumab and Atezolizumab Shows Superior Response in First-Line Esophageal Cancer: The MORPHEUS-EC Trial

The phase 1b/2 MORPHEUS-EC trial demonstrates that adding the anti-TIGIT antibody tiragolumab to atezolizumab and chemotherapy significantly improves objective response rates (67.7%) in patients with previously untreated, locally advanced or metastatic esophageal cancer, providing a promising new therapeutic strategy.
Dual TIGIT/PD‑1 Blockade with Domvanalimab + Zimberelimab Plus FOLFOX Shows Promising Activity in First‑Line Advanced Gastric and GEJ Adenocarcinoma

Dual TIGIT/PD‑1 Blockade with Domvanalimab + Zimberelimab Plus FOLFOX Shows Promising Activity in First‑Line Advanced Gastric and GEJ Adenocarcinoma

A phase 2 arm of the EDGE‑Gastric trial reports a 59% confirmed objective response rate and median PFS 12.9 months with domvanalimab (anti‑TIGIT) plus zimberelimab (anti‑PD‑1) combined with FOLFOX in untreated HER2‑negative advanced gastric/GEJ/esophageal adenocarcinoma, with a manageable safety profile.

Dual TIGIT and PD‑1 Blockade with Domvanalimab + Zimberelimab plus FOLFOX Shows Promising Activity in First‑Line Advanced HER2‑Negative Gastroesophageal Adenocarcinoma

In a phase 2 cohort (EDGE‑Gastric A1), domvanalimab (anti‑TIGIT) plus zimberelimab (anti‑PD‑1) combined with FOLFOX produced a 59% ORR, median PFS 12.9 months and median OS 26.7 months in 41 previously untreated HER2‑negative gastroesophageal adenocarcinoma patients, with immune‑related AEs in 27%.
