“This positive CHMP opinion builds on our efforts to treat advanced gastric and gastroesophageal junction cancer in Europe, including in patients with HER2-negative disease, which accounts for the vast majority of gastric cancer cases,” said Dr. Marjorie Green, senior vice president and head of late-stage oncology, global clinical development, Merck Research Laboratories. “We look forward to the European Commission’s decision and are excited to potentially provide an immunotherapy regimen to patients in the EU with locally advanced unresectable or metastatic HER2-negative gastric or gastroesophageal junction cancer, whose tumors express PD-L1 with a combined positive score ≥1.”
