Astellas Submits New Drug Application for Zolbetuximab in Japan

Japanese pharmaceutical company Astellas Pharma has submitted a New Drug Application (NDA) to Japan's Ministry of Health, Labour and Welfare for zolbetuximab, an investigational Claudin 18.2-targeted monoclonal antibody being evaluated as a first-line treatment for patients with locally advanced unresectable or metastatic HER2-negative gastric or gastroesophageal junction adenocarcinoma whose tumors are CLDN18.2-positive. If approved, it would be the first CLDN18.2-targeted therapy available in Japan for these patients. Gastric cancer kills 50,000 people per year in Japan and remains the third deadliest cancer in the country despite efforts to reduce its impact. The NDA is based on results from the Phase 3 SPOTLIGHT and GLOW clinical trials.
