Status Recruiting

Clinical Trial Summary

To evaluate efficacy and safety of Neoadjuvant of Sintilimab Combined Weekly Metronomic Chemotherapy (PLOF) in resectable locally advanced gastric cancer.

Clinical Trial Description

This is a single-arm clinical study to enroll 50 patients with gastric cancer (cTNM diagnosis of cT3-4aN1-3M0). Each enrolled patient will be assigned a case number. Both this case number and the patient's initials will be entered on each page of the case report form.

Enrolled patients receive a neoadjuvant regimen of POLF in combination with sindilizumab:

preoperatively, they receive a POLF regimen (paclitaxel 60 mg/m2, oxaliplatin 50 mg/m2, and 5-fluorouracil 425 mg/m2) administered once weekly for a total of 6 doses, and in combination with sindilizumab 200 mg intravenously once every 3 weeks for a total of 2 doses. Upon completion of the evaluation, patients whose tumors were judged to be resectable underwent radical surgery and received six postoperative doses of the POLF regimen and two doses of Sindilizumab as adjuvant therapy.

Postoperative imaging evaluations will be performed every three months until disease recurrence. Survival follow-up was performed every three months after disease recurrence. Patients will receive neoadjuvant therapy for 6 weeks preoperatively and adjuvant therapy for 6 weeks postoperatively unless intolerable toxicity occurs, the patient refuses to continue treatment, or treatment is delayed beyond 3 weeks. Patients will be under study observation during treatment and 30 days after treatment termination, and will receive long-term follow-up for 5 years postoperatively. Ultimately, pCR and MPR will be the primary study endpoints, and ORR, DCR, 2-year PFS rate, 3-year OS rate and safety will be the secondary study endpoints to evaluate the efficacy and safety of the neoadjuvant regimen of POLF combined with sindilizumab, as well as to explore the immune activation effect and mechanism of the regimen using peripheral blood and tumor tissue samples. ;
