AZD0901 Compared With Investigator's Choice of Therapy in Participants With Second- or Later-line Advanced or Metastatic Gastric or Gastroesophageal Junction Adenocarcinoma Expressing Claudin18.2

589 patients around the world
Available in Brazil, United States
This is a Phase III, multi-center, open-label, sponsor-blinded, randomized, global study to assess the efficacy and safety of AZD0901 compared to Investigator's choice of therapy as the 2L+ treatment for participants with advanced or metastatic gastric or GEJ adenocarcinoma expressing CLDN18.2, and the clinical performance of the investigational IVD. As part of this combined approach, the efficacy analyses from this study will also provide the basis to evaluate the clinical performance of Ventana CLDN18.2 assay as an IVD device for the identification of patients with advanced or metastatic gastric or GEJ adenocarcinoma expressing CLDN18.2 who may benefit from AZD0901.
