Clinical Trial Summary

To evaluate efficacy and safety of peri-operative sintilimab in combination with SOX in resectable locally advanced gastric or gastroesophageal junction adenocarcinoma

Recruitment information / eligibility

• Status: Recruiting
• Enrollment: 210
• Est. completion date: June 21, 2024
• Est. primary completion date: June 21, 2023
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years to 75 Years

Eligibility

Inclusion Criteria:

• Male or female, 18 years old = age = 75 years old
• ECOG PS score 0-1
• Treatment naive patients diagnosed as gastric adenocarcinoma or gastroesophageal junction adenocarcinoma by histopathology
• No known HER2-positive status;
• Clinical stage ?, ? (T1-4a N+ M0, T3-4a N0 M0, AJCC 8th)
• The research center and the surgeon can complete D2 radical gastrectomy
• Physical condition and organ function allow for larger abdominal surgery
• Sufficient organ and bone marrow function, which is defined as follows:

1. Blood routine: absolute neutrophil count (ANC)=1.5×109/L; platelet count (PLT)=100×109/L; hemoglobin content (HGB)=9.0 g/dL.

2. Liver function: Patients without liver metastasis require serum total bilirubin (TBIL) =1.5×upper limit of normal (ULN); alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =2.5 ×ULN;

3. Renal function: Creatinine clearance rate (Ccr) =50 mL/min (calculated by

Cockcroft/Gault formula):

1. Female: Ccr= (140-years old) x weight (kg) x 0.85/(72 x serum creatinine (mg/dL))

2. Male: Ccr= (140-years old) x weight (kg) x 1.00/(72 x serum creatinine (mg/dL))

4. The coagulation function is adequate, defined as the international normalized ratio (INR) or prothrombin time (PT) = 1.5 times ULN; if the subject is receiving anticoagulation therapy, as long as the PT is within the proposed range of anticoagulation drugs
