Nivolumab, S-1 Combined With Oxaliplatin Versus Nivolumab as Neoadjuvant Therapy in Advanced Gastric Cancer
Study Details
Study Description
Brief Summary
The trial is a prospective, randomized, controlled phase Ⅱ study which will be conducted in Chinese PLA General Hospital, Beijing, China. Patients with eligibility will enrolled and assigned into either group A for 9 weeks of nivolumab, S-1 combined with oxaliplatin (Nivo+SOX) followed by D2 surgery and group B for 9 weeks of nivolumab followed by D2 surgery. The primary endpoint is the safety assessed by recording adverse events and the secondary endpoints are response rate, disease control rate, pathological complete response rate, D2 rate and R0 rate.

Experimental: Nivo + SOX Nivolumab plus SOX |
Drug: Nivolumab plus SOX
The preoperative therapy consists of three-week cycles of intravenously administered nivolumab 360mg and oxaliplatin 130mg/m2 on day 1, and orally administered S-1 40-60 mg twice a day (BID) on day 1 to 14. The dose of S-1 depends on body surface area (BSA): BSA<1.25 m2, 40mg; 1.25<BSA<1.50 m2, 50mg; BSA>1.50 m2, 60mg. Day 15 to day 21 is the rest period.
Other Names:
Procedure: Gastrectomy
A standard D2 radical laparoscopic gastrectomy according to the CSCO clinical guidelines for the diagnosis and treatment of gastric cancer is planned 3-4 weeks after the last cycle of preoperative therapy.
