Breakthrough in Immunotherapy for Gastric and GEJ Cancers

The MATTERHORN trial has yielded promising results, potentially expanding access to immunotherapy for patients with early-stage or locally advanced gastric and gastroesophageal junction (GEJ) cancers.

Nancy Ghattas, VP, US Oncology Commercial Franchise Head of Immuno-Oncology at AstraZeneca, discussed the trial's significance in a video interview with Applied Clinical Trials.

The Imfinzi-based perioperative regimen demonstrated a 22% reduction in the risk of death and improved overall survival regardless of PD-L1 status.

This breakthrough marks the first immunotherapy in this setting to show such benefit, reshaping biomarker strategies in cancer treatment.
