Summary

To evaluate the efficacy and safety of Sintilimab combined with apatinib and chemotherapy as First-line or second-line Therapy in Treatment of HER-2 negative MSS Advanced or Metastatic GC or GEJ Cancer. At the same time, the correlation between tissue programmed death ligand-1(PD-L1) expression and blood circulating tumor cell(CTC) counts and the efficacy of immune combination therapy was also explored.

Description

Participants receive Sintilizumab 200 mg, intravenously (IV) every 3 weeks(Q3W);plus Apatinib 250 mg twice daily (BID) by continous oral adminstration for 14 days, followed by a recovery period of 7 days; plus Tegafur gimeracil oteracil potassium capsules (40mg for body surface area < 1.25/m^2, 50mg/m^2 for body surface area 1.25-1.5m^2, 60mg for body surface area > 1.5/m^2) BID by continous oral adminstration for 14 days, followed by a recovery period of 7 days, plus Oxaliplatin 85 mg/m^2, IV Q3W; for 4-6 cycles followed by Cindilizumab plus Tegafur gimeracil oteracil potassium capsules.

Eligibility

Yes No Not Sure

Inclusion Criteria

Patients with inoperable advanced, recurrent or metastatic gastric and gastroesophageal junction adenocarcinoma confirmed by histology, and HER-2 negative by immunohistochemistry. HER-2 negative was defined as immunohistochemistry 0-1 + or 2 + but fish results were negative
According to recist1 1 measurement standard at least one or more target lesions can be measured
Patients with microsatellite stability (MSS type) or normal mismatch repair protein (PMMR) confirmed by immunohistochemistry or second-generation sequencing
Aged 18-75
The performance status of the Eastern Cooperative Oncology Group (ECOG) is 0-1 points
Life expectancy is more than 3 months
The blood routine examination was basically normal within 1 week before enrollment (taking the normal value in the laboratory of each research center as the standard). The white blood cell count (WBC) ≥ 2.5 × 10^9 / L or neutrophil count (ANC) ≥ 1.5 × 10^9/L; Platelet count (PLT) ≥ 100 × 10^9/L; Hemoglobin ≥ 9.0 g / dl. Patients can receive blood transfusion or erythropoietin treatment to meet this standard
The liver and kidney function, nail function and coagulation function were basically normal within 1 week before enrollment (based on the normal values in the laboratories of each research center). Total bilirubin (TBIL) ≤ 1.5 × Upper limit of normal value (ULN); alanine aminotransferase (SGPT / ALT) ≤ 2.5 × ULN (patients with liver metastasis) ≤ 5 × ULN);Aspartate aminotransferase (SGOT / AST) ≤ 2.5 × ULN (patients with liver metastasis) ≤ 5 × ULN);Creatinine clearance rate (CCR) ≥ 60 ml / min; Urinary protein < 2 +; If urinary protein ≥ 2 +, 24-hour urinary protein must be ≤ 1g; Thyroid stimulating hormone (TSH) ≤ upper limit of normal value (ULN); in case of abnormality, T3 and T4 levels shall be measured; if T3 and T4 levels are normal, they can be selected. International normalized ratio (INR) ≤ 1.5, prothrombin time (PT) and activated partial thromboplastin time (APTT) ≤ 1.5 × ULN。
The patient is willing and able to comply with the provisions of the study protocol during the study
Before entering the study, during the study and within 6 months after the end of treatment, patients with fertility must take effective contraceptive measures (hormone or barrier contraception; abstinence)
The subject agreed not to participate in another intervention study when receiving the study drug in this study. Subjects ended the last study for more than 1 month
Subjects who have received adjuvant or neoadjuvant therapy (including chemotherapy, radiotherapy or chemoradiotherapy) of GC / GEJ must complete the last dose of treatment at least 6 months before the first study treatment. Palliative radiotherapy is allowed, but it must be completed 2 weeks before the start of study treatment

Exclusion Criteria

Patients who have received chemotherapy, radiotherapy or biological therapy within two weeks. Received any investigational drug within 4 weeks before the start of study treatment
Pregnant or lactating women; women with fertility have a positive pregnancy test or no pregnancy test at the time of screening
Severe / uncontrolled intermittent disease / infection
Obvious cardiovascular disease (history of congestive heart failure > NYHA class II, unstable angina pectoris or myocardial infarction, unstable angina pectoris or myocardial infarction, or severe arrhythmia in the past six months)
History or evidence of hereditary bleeding syndrome or coagulation disease with bleeding risk, history of thrombotic disease and active gastrointestinal bleeding
There have been arterial thromboembolism events in the past 6 months, including transient ischemic attack and cerebrovascular accident
Patients with previous malignant tumors, unless the previous malignant tumors have been diagnosed and treated for more than 5 years, and there is no evidence of recurrence
The subjects have known human immunodeficiency virus (HIV) infection or known positive detection history of active hepatitis B (positive HBsAg) or hepatitis C infection. The subjects with HBsAg negative but HBC AB positive will be tested for HBV DNA replication. If it is greater than the minimum copy number of HBV DNA, the subjects will be excluded. The subjects with seropositive but hepatitis C virus The subjects with negative replication results of (HCV) RNA test are eligible for inclusion
Patients with neuropathy > grade 3 at screening
Patients with QTc > 500msec during screening
Patients with meningeal disease and no other measurable brain metastasis were excluded
Have received bevacizumab, sorafenib, sunitinib or other VEGF pathway targeted therapy
Have a history of severe hemoptysis
Having a mental illness or social situation can hinder study compliance
A severe nonunion wound, ulcer, or bone fracture
Major surgery, open biopsy or major trauma within 28 days before enrollment, and minor surgery within 7 days before enrollment
Have a history of allergic reaction to compounds similar to the chemical composition of the study drug
Take chronic daily aspirin (> 325 mg / day), dipyridamole, ticlopidine, clopidogrel, cilostazol, non steroidal anti-inflammatory drugs and other drugs known to inhibit platelet function
Recent formal antihypertensive treatment still failed to control hypertension (systolic blood pressure greater than 140mmHg and diastolic blood pressure greater than 90mmHg), and the patients had obvious symptoms of hypertension
