- Radical radiotherapy within 4 weeks prior to first dosing;
- Patients have dysphagia;
- History of pulmonary fibrosis, interstitial pneumonia, pneumoconiosis, radiation pneumonitis, drug-related pneumonia, severe impairment of the lung function, etc., which may interfere with the detection and treatment of suspected drug-related lung toxicity, except radiation pneumonitis in the radiation treatment area;
- Confirmed human immunodeficiency virus (HIV) infection or confirmed syphilis; Patients have high risk of bleeding events such as unhealed wounds, ulcers, fractures,or. patients have active ulcer of stomach and duodenum, ulcerative colitis and other digestive tract diseases or unresectable tumors with active bleeding, or other conditions that may cause gastrointestinal bleeding and perforation, as judged by investigators;
- The adverse events due to previous anti-tumor therapy has not recovered to ≤ CTCAE Grade 1, except alopecia and peripheral neurotoxicity with ≤ CTCAE grade 2 caused by platinum chemotherapy;
- Patients with active infection and still need systemic treatment;
- Steroids (more than 10 mg/day prednisone or other equivalent hormones) or other immunosuppressive agents for systemic therapy within 4 weeks prior to first dosing, except nasal spray, inhaled or other topical use of steroid (i.e. no more than 10mg/day prednisone or equivalent doses of other corticosteroids);
- Any live or attenuated live vaccine within 4 weeks prior to first dosing;
- Major surgeries within 4 weeks prior to first dosing;
- Any anti-tumor traditional Chinese medicine taken within 2 weeks prior to first dosing;
- History of allergies to any ingredient of Sintilimab or Fruquintinib or GM-CSF;
- Participating in other interventional clinical studies within 4 weeks;
- Female patients with pregnancy or breastfeeding;

- History of any active autoimmune disease or autoimmune disease, including but not limited to interstitial pneumonia, uveitis, inflammatory bowel disease, hepatitis, pituitary inflammation, vasculitis, systemic lupus erythematosus, etc. (except patients with hypothyroidism that can be controlled only by hormone replacement therapy and patients with type I diabetes who only need insulin replacement therapy);
- Patients with uncontrolled epilepsy, central nervous system disease, or mental disorders whose clinical severity, as determined by the investigator, may prevent the signing of the informed consent or any condition by which investigators judge patients not suitable to participate in this study.
