Recruitment & Eligibility

• Status: UNKNOWN
• Sex: All
• Target Recruitment: 63

Inclusion Criteria

• Age at least 18 years.

• ECOG PS 0-1.

• Pathologically confirmed stage IV NSCLC.

• Negative for driver genes including EGFR，ALK，and ROS-1.

• Patients with disease progression after first-line platinum-based therapy without anti-PD-1 or PD-L1 treatment.

• Patients with at least one lesion (size 1-5cm) eligible for SBRT (24Gy/3Fx) and simultaneously at least one measurable lesion (in addition to the lesion treated with SBRT) as defined by RECIST1.1.

• Patients with brain metastasis are eligible if they are asymptomatic, neurologically stable, and off corticosteroids.

• Life expectancy of more than 3 months.

• Patients with no indications for palliative radiotherapy in the opinion of the investigator.

• Patients with a prior history of surgery are eligible if they have recovered adequately from the toxicity and/or complications of surgery.

• Signed informed consent for the use of fresh tumor biopsies before and during the treatment.

• Women of childbearing age and men must agree to use effective contraception during the trial.

• Adequate organ function within 1 week prior to the enrollment：

  1. Adequate bone marrow function: hemoglobin ≥80g/L, white blood cell (WBC) count ≥ 4.0 * 10 ^ 9/L or neutrophil count ≥ 1.5 * 10 ^ 9/L, and platelet count ≥ 100 * 10 ^ 9/L;
  2. Adequate hepatic function: total bilirubin < 1.5 x upper limit of normal (ULN). Note: If total bilirubin is > 1.5 x ULN, direct bilirubin must ≤ ULN, Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) ≤2.5 ULN;
  3. Adequate renal function: serum creatinine ≤ 1.5 x ULN or creatinine clearance ≥ 50 mL/min;

• Ability to understand and willingness to provide the informed consent.

Exclusion Criteria

• Prior exposure to immunomodulatory agent,including but limited to anti-PD-1 or anti-PD-L1 antibodies.
• Severe autoimmune disease: inflammatory bowel disease (including Crohn's disease and ulcerative colitis) 、rheumatoid arthritis、scleroderma、systemic lupus erythematosus 、Wegener's granulomatosis and related vasculitides.
• Patients receiving non-platinum-based chemotherapy as first-line treatment
• Mixed small cell with non-small cell lung cancer histology.
• Pregnant or lactating women.
• Symptomatic interstitial lung disease or active infectious/non-infectious pneumonitis.
• History of any other malignancy.
• Patients in whom palliative radiotherapy is indicated in the opinion of the investigator.
• Active infection, congestive heart failure, myocardial infarction within the 6 months prior to enrollment, unstable angina pectoris or cardiac arrhythmia.
• Prior allergic reaction or contraindications to sintilimab and GM-CSF.
• Patients who have received tumor vaccine; or administration of live, attenuated vaccine within 4 weeks before the start of treatment. Note: Influenza vaccination is permitted only during influenza season, while live, attenuated influenza vaccine such as FluMist is not allowed.
• Patients receiving concurrent chemotherapy drugs,other immunosuppressive agents,or other investigational treatment.Long-term corticosteroid users are also excluded.
• Mental disorders, drug abuse, and social condition that may negatively impact compliance in the opinion of the investigator.

SBRT + sintilimab + GM-CSF	GM-CSF	-
SBRT + sintilimab + GM-CSF	Sintilimab	-

Primary Outcome Measures

Name	Time	Method
Overall Objective Response Rate	At least 6 weeks after start of treatment	ORR was defined as the proportion of participants with partial response (PR) or complete response (CR) to treatment as defined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.

Secondary Outcome Measures

Name	Time	Method
Percentage of Participants With Adverse Events	Two years	Treatment-related adverse events were assessed and graded according to CTCAE v. 5.0.
Objective Response Rate (ORR) in Non-irradiated Lesion	At least 6 weeks after start of treatment	Objective Response Rate (ORR) in Non-irradiated Lesion was defined as the proportion of patients with at least 30% reduction from baseline in the longest diameter of any of non-irradiated target lesions defined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 at any time-point from the date of treatment initiation to the date of last follow-up.
Overall Survival	Two years	OS was defined as the time from the date of enrollment until death by any cause. Participants still alive at the time of data analysis were censored at the date of last follow-up.
Progression Free Survival	Two years	PFS was measured from the date of enrollment to the date of disease progression as defined by Response Evaluation Criteria in Solid Tumor (RECIST) Version 1.1 or death due to any cause, whichever occurred first.
