Why CLDN18.2?
Claudin 18.2 (CLDN18.2) is a tight junction protein normally expressed in gastric epithelial cells. In gastric and GEJ adenocarcinomas, CLDN18.2 is frequently overexpressed on the tumor cell surface, making it an attractive therapeutic target.
Approximately 38–52% of gastric/GEJ cancers express CLDN18.2 at levels suitable for targeted therapy. ZELVARA binds specifically to CLDN18.2, engaging the immune system to destroy tumor cells through antibody-dependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC).
