Merck’s cancer drug Keytruda has shown positive results in a confirmatory trial for a rare form of esophageal cancer. The Phase 3 trial demonstrated a statistically significant improvement in progression-free survival for patients with HER2-positive gastric or gastroesophageal junction adenocarcinoma. The treatment reduced the risk of death by 28% in a follow-up of 28.4 months. This is a promising development for patients with advanced gastroesophageal cancer, who historically have faced poor outcomes. Keytruda received regulatory approval in May 2021, and these findings further support its effectiveness in treating this rare form of cancer.
