Zolbetuximab, sold under the brand name Vyloy, is a monoclonal antibody used for the treatment of gastric cancer. It is a claudin 18.2-directed cytolytic antibody against isoform 2 of Claudin-18. Zolbetuximab was developed by Ganymed Pharmaceuticals. Astellas Pharma acquired the rights to zolbetuximab in December 2016, when it acquired Ganymed Pharmaceuticals.

Zolbetuximab was approved for medical use in Japan in March 2024, in the European Union in September 2024, and in the United States in October 2024. The US Food and Drug Administration (FDA) considers it to be a first-in-class medication.
