A Single-Arm Study of QL1706 Combined With DOS as Neoadjuvant Therapy for Locally Advanced Gastric/GEJ Adenocarcinoma

This is an open-label, prospective, interventional study designed to enroll 34 patients with locally advanced gastric or gastroesophageal junction adenocarcinoma, aiming to evaluate and observe the efficacy and safety of QL1706 in combination with DOS for the treatment of locally advanced gastric or gastroesophageal junction adenocarcinoma. Enrolled patients will receive iparomlimab and tuvonralimab in combination with the DOS regimen (docetaxel + oxaliplatin + S-1) administered in 21-day treatment cycles. Subjects who complete 3-4 cycles of treatment and are deemed suitable for surgery will undergo gastrectomy, with the specific interval between neoadjuvant therapy and surgery determined by the investigator based on actual clinical circumstances. Following surgery, clinicians will administer postoperative treatment according to the postoperative pathological assessment results and the clinical practice treatment principles of the study center. The primary endpoint is the pathological complete response rate assessed by postoperative pathological evaluation.
