ClinicalTrials ID:NCT05859477

Patient View

This phase 2 trial assesses nivolumab with CAPOX for FGFR2-positive/PD-L1-positive/HER2-negative metastatic gastric cancer. Eligibility includes untreated advanced gastric adenocarcinoma, measurable lesions, and specific biomarker expressions. Interventions involve nivolumab (360 mg i.v. every 3 weeks), capecitabine, and oxaliplatin. Participants must be adults with adequate organ function.

Patient Parameters

Program Overview

The goal of this phase 2 clinical trial is to evaluate the efficacy of nivolumab in combination with CAPOX in patients with FGFR2-positive/PD-L1-positive/HER2-negative metastatic gastric cancer.

Description

On April 16, 2021, the Food and Drug Administration approved first-line therapy with nivolumab and fluoropyrimidine-platinum-containing chemotherapy for metastatic gastric adenocarcinoma. Patients with PD-L1 expression benefit the most from this treatment.

Fibroblast growth factor receptor 2 (FGFR2) is a predictor of poor overall survival and a potential target for targeted therapy. However, there is no data of nivolumab efficacy in patients with combined expression of PD-L1 and FGFR2.

The aim of this study is to evaluate the preliminary efficacy of nivolumab in this patient population.
