Zolbetuximab
Vyloy (Zolbetuximab) is indicated for the first-line treatment of adults with locally advanced unresectable or metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma that is human epidermal growth factor receptor 2 (HER2)-negative and expresses claudin 18.2 (CLDN18.2), as confirmed by an FDA-approved diagnostic test. It is used in combination with fluoropyrimidine- and platinum-based chemotherapy. This targeted therapy is specifically designed for tumors with CLDN18.2 positivity, a biomarker found in a subset of gastric and GEJ cancers, providing a more personalized treatment approach for eligible patients.
