Adequate organ function, subject will meet the following laboratory criteria: 1) Absolute value of neutrophils (ANC) ≥1.5x10^9/L without the use of granulocyte colony-stimulating factor in the last 14 days. 2) Platelets ≥100×10^9/L in the last 14 days without blood transfusion. 3) In the absence of blood transfusion or erythropoietin in the last 14 days, hemoglobin>9 g/dL. 4) Total bilirubin ≤1.5× upper normal value (ULN); 5) Aspartate aminotransferase (AST), alanine aminotransferase (ALT) ≤2.5×ULN 6) Serum creatinine ≤1.5×ULN and creatinine clearance rate (calculated by Cockcroft-Gault formula) ≥60 mL /min; 7) Good coagulation function, defined as international standardized ratio (INR) or prothrombin time (PT) ≤1.5 ULN; 8) Normal thyroid function, defined as thyroid stimulating hormone (TSH) within the normal range. If the baseline TSH is outside the normal range, subjects with total T3 (or FT3) and FT4 within the normal range may be enrolled; 9) The myocardial enzyme profile is within the normal range (if the investigator comprehensively determines that the simple laboratory abnormality is not clinically significant, it is allowed to be included in the group); 12. For female subjects of reproductive age, a negative urine or serum pregnancy test should be performed within 3 days prior to receiving the first study drug administration (day 1 of cycle 1). If a urine pregnancy test result cannot be confirmed as negative, a blood pregnancy test is requested. Women of childbearing age were defined as at least 1 year after menopause or having undergone surgical sterilization or hysterectomy; If there is a risk of pregnancy, all subjects (both men and women) are required to use a contraceptive with an annual failure rate of less than 1% for the entire treatment period up to 120 days after the last study drug (or 180 days after the last chemotherapeutic drug).

Exclusion Criteria:

1. Malignant diseases other than NSCLC were diagnosed within 5 years prior to first administration (excluding radical basal cell carcinoma of the skin, squamous carcinoma of the skin, and/or radical resected carcinoma in situ); 2. Are currently participating in an interventional clinical study or have been treated with another study drug or study device within 4 weeks prior to initial administration; 3. Prior treatment with anti-PD-1, anti-PD-L1, or anti-PD-L2 drugs or drugs that target another stimulating or co-inhibiting T-cell receptor (e.g., CTLA-4, OX-40, CD137); 4. Received systemic systemic therapy with anti-tumor indications of Proprietary Chinese medicines or immunomodulatory drugs (including thymosin, interferon and interleukin, except for local use to control pleural effusion) within 2 weeks before the first administration; 5. An active autoimmune disease requiring systemic therapy (e.g., palliative drugs, glucocorticoids, or immunosuppressants) has occurred within 2 years prior to first dosing. Alternative therapies (e.g. thyroxine, insulin, or physiologic glucocorticoids for adrenal or pituitary dysfunction) are not considered systemic; 6. Were receiving systemic glucocorticoid therapy (excluding nasal spray, inhalation, or other topical glucocorticoid) or any other form of immunosuppressive therapy within 7 days prior to initial dosing; Note: Physiological doses of glucocorticoids (≤10 mg/ day of prednisone or equivalent) are permitted; 7. Allogeneic organ transplantation (except corneal transplantation) or allogeneic hematopoietic stem cell transplantation is known; 8. Those who are known to be allergic to the active ingredient or excipient of sindilizumab; 9. Has not fully recovered from toxicity and/or complications associated with any intervention prior to initiation of treatment (i.e., ≤ grade 1 or baseline, excluding fatigue or hair loss); 10. Known history of human immunodeficiency virus (HIV) infection (i.e. HIV 1/2 antibody positive); 11. Untreated active hepatitis B (defined as HBsAg positive with hbV-DNA copy number greater than the upper limit of the normal value in the laboratory department of the research center); Note: Hepatitis B subjects who meet the following criteria can also be enrolled: 1) HBV viral load before initial administration < 1000 copies/mL (200 IU/ml). Subjects should receive anti-HBV therapy throughout study chemotherapy to avoid virus reactivation 2) For subjects resistant to HBc (+), HBsAg (-), anti-HBS (-), and HBV viral load (-), prophylactic anti-HBV therapy is not required, but close monitoring of virus reactivation is required 12. Active HCV-infected subjects (HCV antibody positive and HCV-RNA level above the detection limit); 13. Received live vaccine within 30 days prior to initial administration (cycle 1, day 1); Note: Acceptance of injectable inactivated virus vaccine against seasonal influenza is permitted within 30 days prior to first administration; Intranasally administered live attenuated flu vaccines are not allowed. 14. Pregnant or lactating women; 15. Presence of any serious or uncontrollable systemic illness, such as: 1) Serious and uncontrollable abnormalities in the rhythm, conduction or morphology of resting electrocardiogram, such as complete left bundle branch block, heart block above degree ⅱ, ventricular arrhythmia or atrial fibrillation; 2) Unstable angina pectoris, congestive heart failure, NYHA grade ≥ 2 chronic heart failure; 3) Any arterial thrombosis, embolism or ischemia, such as myocardial infarction, unstable angina pectoris, cerebrovascular accident or transient ischemic attack, occurred within 6 months prior to treatment inclusion; 4) Poor blood pressure control (systolic > 140 mmHg, diastolic > 90 mmHg); 5) A history of non-infectious pneumonia requiring glucocorticoid treatment within 1 year prior to initial administration, or the current presence of clinically active interstitial lung disease; 6) Active tuberculosis; 7) The presence of active or uncontrolled infections requiring systemic treatment; 8) Clinical active diverticulitis, abdominal abscess and gastrointestinal obstruction; 9) Liver diseases such as cirrhosis, decompensated liver disease, acute or chronic active hepatitis; 10) Poor control of diabetes (FBG > 10mmol/L); 11) Urine routine showed urine protein ≥++, and confirmed 24-hour urine protein quantity > 1.0g; 12) Patients with mental disorders and unable to cooperate with treatment; Any medical history or disease evidence that may interfere with the study results, prevent the subjects from participating fully in the study, abnormal values of treatment or laboratory tests, or other conditions that the investigator considers inappropriate for the study because of other potential risks that the investigator considers inappropriate for the study.
