Eligible patients for this study must have locally advanced, Stage III NSCLC that is considered unresectable. histologically- or cytologically-documented NSCLC who present with locally advanced, unresectable (Stage III) disease (according to Version 8 of the International Association for the Study of Lung Cancer Staging Manual in Thoracic Oncology). Patients must not have progressed following definitive, platinum-based, concurrent chemoradiation therapy.
First dose of study treatment is no later than 42 days after cCRT.
Adequate organ function as indicated by the following laboratory values (obtained ≤ 7 days before first dose)
1. Absolute neutrophil count (ANC) ≥ 1.5 × 10^9/L,
2. Platelets ≥ 100 × 10^9/L,
3. Hemoglobin ≥ 90 g/L.
4. International normalized ratio (INR) or prothrombin time (PT) ≤ 1.5 x upper limit of normal (ULN).
5. Activated partial thromboplastin time (aPTT) ≤ 1.5 x ULN.
6. Serum total bilirubin ≤ 1.5 x ULN.
7. Aspartate and alanine aminotransferase (AST and ALT) ≤ 2.5 x ULN.
8. Serum albumin ≥25 g/L（2.5 g/dL).
9. Serum creatinine ≤ 1.5 x ULN or estimated glomerular. filtration rate (GFR) >50 mL/min by Cockcroft-Gault equation.
Able to provide written informed consent by the patient or by the patient's legally acceptable representative and can understand and agree to comply with the requirements of the study.
Patients of childbearing potential must be willing to use a highly effective method of birth control for the duration of the study, and ≥ 120 days after the last dose of study drugs.

Exclusion criteria

Any condition that required systemic treatment with either corticosteroids (> 10 mg daily of prednisone or equivalent) or any other immunosuppressive medication≤ 14 days before first dose of study drugs that may affect study treatment estimated by investigator.
Severe chronic or active infections requiring systemic antibacterial, antifungal, within 14 days prior to first dose of study drug(s).
Prior allogeneic stem cell transplantation or organ transplantation.
Any of the following cardiovascular risk criteria:
1. Cardiac chest pain, defined as moderate pain that limits instrumental activities of daily living, ≤ 28 days before first dose of study drugs.
2. Symptomatic pulmonary embolism ≤ 28 days before first dose of study drugs.
3. Any history of acute myocardial infarction ≤ 6 months before first dose of study drugs.
4. Any history of heart failure meeting New York Heart Association Classification III or IV ≤ 6 months before first dose of study drugs.
5. Any event of ventricular arrhythmia ≥ Grade 2 in severity ≤ 6 months before first dose of study drugs.
6. Any history of cerebrovascular accident ≤ 6 months before first dose of study drugs.
7. QTc interval (corrected by Fridericia's method) > 450 msec (for males)/ > 470 msec (for females). Note: If QTc interval is > ULN on initial ECG, a follow up ECG will be performed to exclude result.
8. Current left ventricular ejection fraction (LVEF) < institutional LLN as assessed by echocardiography (ECHO).

Pregnant or breastfeeding woman.
Concurrent participation in another clinical study unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study.
