Chemoradiotherapy and SHR-1701 in Patients With Unresectable Gastric Cancer

Conditions
Summary
Gastric Cancer is one of the leading causes of cancer-related death worldwide, and patients with unresectable locally advanced or metastatic disease have a poor prognosis. This study aims to evaluate the safety and efficacy of radiotherapy combined with CAPOX and SHR-1701, a PD-L1/TGF-β bispecific antibody, in patients with unresectable locally advanced or metastatic gastric or gastroesophageal junction adenocarcinoma. By improving local tumor control and enhancing systemic antitumor activity, this study seeks to increase the opportunity for curative-intent resection and improve survival outcomes in patients with advance gastric cancer.

Interventions
CAPOX consists of oxaliplatin (130 mg/m²) administered intravenously on day 1 and capecitabine (1,000 mg/m²) administered orally twice daily on days 1-14 of each 21-day cycle (Q3W) according to the study protocol.
Radiotherapy will be delivered to the primary tumor (30 Gy in 10 fractions) and metastatic lesions (25-35 Gy in 5-7 fractions), with the dose determined according to the location, number, and size of metastatic lesions and normal tissue dose constraints in accordance with the study protocol.
SHR-1701 (1800 mg) will be administered intravenously on day 1 or each 21-day cycle (Q3W) according to the study protocol.
