Japan’s Ministry of Health, Labor and Welfare approved Astellas Pharma Inc.’s Vyloy (zolbetuximab) to treat a type of advanced gastric cancer on March 26, making it the first anti-claudin 18.2 monoclonal antibody to gain regulatory clearance worldwide.
CMG901 induced responses with a manageable toxicity profile in patients with CLDN18.2-positive gastric or gastroesophageal junction cancer, according to updated data from the dose-expansion phase of the phase 1 KYM901 study.
Kevin M. Waters, MD, PhD, discusses key findings from a study that reinforced the rationale for Claudin18.2 testing, the prevalence of this protein in gastric cancers, and how this potential therapeutic target represents the evolving role of pathology in cancer diagnosis and care.
