Combining tirelizumab with chemotherapy for treating advanced gastric cancer

Clinical Efficacy and Safety of Tirelizumab Combined With Chemotherapy in the Treatment of HER-2 Negative Locally Advanced Resectable Gastric Cancer

Phase 2 Interventional Chinese PLA General Hospital · NCT06284746

This study is testing if combining a new immunotherapy called tirelizumab with chemotherapy can help people with advanced gastric cancer feel better compared to just chemotherapy alone.

What this trial studies

This clinical trial evaluates the safety and effectiveness of tirelizumab, an immunotherapy, combined with chemotherapy in patients with HER-2 negative locally advanced gastric cancer. It employs a prospective randomized controlled trial design to compare outcomes between patients receiving the combination therapy and those receiving chemotherapy alone. Key metrics for evaluation include pathological response rates, disease-free survival rates, and the incidence of adverse events. The goal is to establish a foundation for larger multicenter studies based on the findings.

Who should consider this trial

Good fit: Ideal candidates are patients with locally advanced HER-2 negative gastric or gastroesophageal junction adenocarcinoma who are eligible for surgical treatment.

Not a fit: Patients with distant metastasis or those with active autoimmune diseases or serious cardiovascular conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve treatment outcomes and survival rates for patients with advanced gastric cancer.

How similar studies have performed: While there have been studies exploring immunotherapy in gastric cancer, the specific combination of tirelizumab with SOX/XELOX chemotherapy is relatively novel.
