combination therapy of sintilimab and anlotinib as a first-line treatment in advanced nsclc (sunrise)

Conditions: Carcinoma; Non-small Cell Lung Cancer

Summary: this is an open label, multi-center, randomized control phase ii trial, to compare the efficacy and safety of sintilimab combined with anlotinib versus standard platinum-based chemotherapy as a first-line treatment in advanced nsclc patients without driven-gene mutations.

this is an open label, multi-center, randomized control study comparing the combination of sintilimab and anlotinib with standard platinum-based chemotherapy in treat-naïve advanced (unresectable stage iiib, iiic and iv patients without driven-gene mutations) nsclc patients. eligible subjects are 1:1 randomized into the experimental group (sintilimab combined with anlotinib) or the control group (standard platinum-based chemotherapy).

small cell lung cancer (including small cell cancer and non-small cell mixed lung cancer). 2. patients with cavernous squamous cell carcinoma or imaging suggesting infiltration/invasion of large blood vessels or other high bleeding risk factors evaluated by the investigators. 3. active hemoptysis within 2 weeks before first drug administration (at least 1/2 teaspoon blood spilt at one time); 4. received radiotherapy before administration of the first study drug, which met one of the following conditions: 1) ≥30% of bone marrow had received radiotherapy within 14 days before treatment 2) received radiotherapy for lung lesions within 6 weeks before treatment with \>30gy dose (enrolled subjects must recover from the toxicity of previous radiotherapy to level 1 or below, do not need glucocorticoid treatment and have no history of radiation pneumonia) 3) the end time of palliative radiotherapy should be within 7 days before the first study drug administration 5. major surgical treatment within 3 weeks of the first study drug administration (except for biopsy surgery) 6. have participated in other clinical studies or less than 4 weeks before the end of treatment in the previous clinical study 7. previously diagnosis as other malignant tumors within 5 years prior to the first dose of study treatment, with the exception of: skin basal cell carcinoma or squamous cell carcinoma with radical treatment, and/or carcinoma in situ underwent radical resection 8. prior treatment with pd-1 inhibitor, pd-l1 inhibitor, ctla4 inhibitor, or anti- angiogenic treatment. 9. a history of active autoimmune disease requiring systemic treatment (e.g. using drugs for disease remission, corticosteroids or immunosuppressor) within 2 years prior to the first dose of study treatment. substitution therapy (e.g. thyroxine, insulin or physiological corticosteroids for treating adrenal or pituitary dysfunction) is not considered as a systemic treatment. 10. received a traditional chinese medicine with anti-tumor effect, or an immunomodulatory drug (thymosin, interferon, interleukin) within 2 weeks before the first dose, or received major surgery within 3 weeks before the first dose 11. systemic steroid therapy or any other form of immunosuppressive therapy performed within 7 days prior to the first dose of study (physiologic dose is allowed). 12. the presence of clinically uncontrollable pleural effusion/peritoneal effusion 13. have received a physical organ or blood system transplant 14. allergic to the active ingredients or excipients of the drugs studied, such as sintilimab, pemetrexed, gemcitabine, carboplatin, cisplatin, etc. 15. patients with multiple factors that affect oral medications (such as inability to swallow, gastrointestinal resection, chronic diarrhea, and intestinal obstruction) 16. patients with bleeding tendencies (such as active gastrointestinal ulcers) or treated with anticoagulants or vitamin k antagonists such as warfarin, heparin or their analogues; small doses of warfarin (≤1mg/d), small doses of heparin (≤ 12,000 u/d) or small doses of aspirin (≤100mg/d) are allowed for prophylactic purposes, provided that the international standardized ratio of prothrombin time (inr) ≤1.5 17. patients with severe arteriovenous thrombosis, such as cerebrovascular accident (including temporary ischemic attack), deep vein thrombosis and pulmonary embolism, which occurred within 6 months before the first treatment 18. not fully recovered from toxicity and/or complications resulting from any intervention prior to initiation of treatment (i.e., ≤1 or baseline, excluding fatigue or hair loss);
