The study comprises three open-label substudies in patients with HER2-negative adenocarcinoma of the stomach or gastro-esophageal junction harboring FGFR2 gene translocations, FGFR2 gene amplifications, or FGFR1-3 mutations. Patients will be treated with single-agent derazantinib or derazantinib in combination with paclitaxel, ramucirumab, or atezolizumab. The study enrolls patients with either metastatic or recurrent locally advanced HER2-negative adenocarcinoma of the stomach or gastro-esophageal junction inoperable at the time of screening, and radiologically confirmed disease progression after one or at least one standard treatment regimen.
The purpose of this study is to evaluate the efficacy of derazantinib monotherapy or derazantinib in combination with paclitaxel, ramucirumab, or atezolizumab in patients with HER2-negative adenocarcinoma of the stomach or gastro-esophageal junction harboring FGFR2 genetic aberrations (GA).
