FMT+SOX+Sintilimab As First-line Treatment for Advanced Gastric Cancer

Recruiting now · Phase 2 · Has a placebo group

Conditions studied: Gastric Cancer

In brief

the investigators plan to initiate a prospective, multicenter, randomized, double-blind, placebo-controlled phase II study, recruiting 198 patients with advanced gastric/gastroesophageal junction adenocarcinoma who have not received prior treatment. Randomly divided into two groups, one group is the group of fecal microbiota transplantation(FMT)+SOX+Sintilimab, and the other group is the group of SOX+Sintilimab. Compare the 2-year OS rates of the two groups to verify whether the addition of FMT to first-line treatment can improve the prognosis of gastric cancer patients.

• The physical status score of Eastern Tumor Collaboration Group (ECOG) was 0-1;
• Expected survival time ≥ 3 months;
• Have adequate organ and bone marrow function, laboratory examination within 7 days prior to enrollment meets the following requirements (no blood components, cell growth factors, albumin or other corrective drugs are allowed within 14 days prior to obtaining laboratory examination), as follows: 1) Blood routine: absolute neutrophil count (ANC) ≥1.5×109/L, platelet (PLT) ≥75×109/L, hemoglobin (HGB) ≥90 g/L (no blood transfusion or erythropoietin dependence within 14 days); 2) Liver function: serum total bilirubin (TBIL) ≤2 times the upper limit of normal (ULN); Alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) ≤ 5x ULN, serum albumin ≥28 g/L; alkaline phosphatase (ALP) ≤5×ULN; 3) Renal function: serum creatinine (Cr) ≤1.5×ULN, or creatinine clearance ≥50 mL/min (using the standard Cockcroft-Gault formula) : Urine routine results showed urinary protein < 2+; For patients with urine protein ≥2+ at baseline,24-hour urine collection and 24-hour urine protein quantification<1g should be performed; 4) Coagulation function: International standardized ratio (INR) or prothrombin time (PT) ≤1.5 times ULN; If the subject is receiving anticoagulant therapy, as long as the INR is within the intended range of anticoagulant drug use.
• For female subjects of reproductive age, a urine or serum pregnancy test should be performed and the result is negative 3 days prior to receiving the initial study drug administration;
• Subjects and their sexual partners are required to use a medically approved contraceptive method (such as an IUD, contraceptive pill, or condom) during the study treatment period and for 6 months after the end of the study treatment period.

You may not qualify if…

• Currently participating in an interventional clinical study or receiving another investigational drug or investigational device within 4 weeks prior to initial dosing;
• Received proprietary Chinese medicines with anti-tumor indications or immunomodulatory drugs (thymosin, interferon, interleukin, etc.) within 2 weeks before the first administration, or received major surgical treatment within 3 weeks before the first administration;
