Comparing Modified XELOX Plus Sintilimab With Standard XELOX Plus Sintilimab in First-line Treatment for HER2-negative Gastric/Gastroesophageal Junction Adenocarcinoma

Is NCT05918094 recruiting? Yes, currently enrolling (May 2026). This Phase 3 trial studies multiple treatments including Experimental dose: modified XELOX + sintilimab and Standard dose: standard XELOX + sintilimab for gastric cancer.

Phase 3RecruitingSun Yat-sen UniversityNCT05918094Data as of May 2026

Treatment: Experimental dose: modified XELOX + sintilimab · Standard dose: standard XELOX + sintilimabThis is a randomized, controlled, multicenter phase Ⅲ study to evaluate the therapeutic efficacy of modified XELOX plus sintilimab versus standard XELOX plus sintilimab in subjects with advanced HER2-negative gastric or gastroesophageal adenocarcinoma in the first-line treatment. The primary outcome is the progression-free survival (PFS), with a planned enrollment of 540 subjects.
