Brief summary: To evaluate the efficacy of Surufatnib combined with Toripalimab compared with FOLFIRI in the treatment of advanced neuroendocrine carcinoma

Detailed description: This is a randomized, controlled, open-label, multicenter, phase III clinical study designed to evaluate the efficacy and safety of surufatnib combined with toripalimab compared with FOLFIRI in patients with advanced neuroendocrine carcinoma who have progression of disease or intolerable toxicity after previous 1st-line chemotherapy.

Eligibility criteria: Inclusion Criteria:

* Patients who included in this study must fulfil all of the following criteria:

  1. Fully aware of this study and voluntary to sign the informed consent form (the informed consent form must be signed before any trial-specific procedure is performed);
  2. Aged 18\~75 years (inclusive);
  3. Histologically or cytologically confirmed, unresectable, locally advanced or metastatic neuroendocrine carcinoma
  4. Patients with neuroendocrine carcinoma who have failed previous platinum-based 1st-line chemotherapy

  8. Patients with adequate bone marrow, liver and kidney organ functions whose laboratory tests within 7 days before the first dose meet the following requirements:

     1. Absolute neutrophil count (ANC) ≥1.5×109/L, platelet count ≥100×109/L and hemoglobin ≥90 g/dL (without blood transfusion or use of blood products for correction within 14 days prior to laboratory examination, and without use of granulocyte colony stimulating factor or other hematopoietic stimulating factor for correction within 7 days prior to laboratory examination);
     2. Serum total bilirubin ≤1.5 × upper limit of normal (ULN);
     3. Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≤2.5 × ULN in the absence of liver metastases; ALT and AST ≤5 × ULN in the presence of liver metastases.
     4. Serum creatinine ≤ 1.5 × ULN and creatinine clearance ≥ 50 mL/min (calculated according to the Cockcroft-Gault formula, see Appendix 3);
     5. Routine urinalysis showing urine protein \< 2+; in case of urine protein ≥ 2+, 24-hour urine protein (quantitative) should be \<1g;

  9. Estimated survival ≥ 12 weeks;
  10. Females of childbearing potential must have a negative serum pregnancy test within 7 days prior to the first dose. Male or female patients of childbearing potential volunteer to use effective contraceptive methods during the study and within 90 days after last administration of the study drug, such as double barrier contraception, condoms, oral or injectable contraceptives, intrauterine contraceptive device, etc. All female patients will be considered to be of childbearing potential unless they are naturally postmenopausal, underwent artificial menopause, or are surgically sterile (e.g., hysterectomy, bilateral adnexectomy).

Exclusion Criteria:

* Subjects must be excluded from this study when any one of the following criteria is met:

  1. Toxicities associated with previous anti-tumor treatment do not return to ≤CTCAE grade 1, except for alopecia and peripheral neurotoxicity (≤ CTCAE grade 2 ) caused by Oxaliplatin;

Use of approved systematic anti-tumor therapy within 4 weeks prior to the first dose, including chemotherapy, biotherapy, targeted therapy (the washout period of small molecular targeted drugs lasts 2 weeks or 5 half-lives, whichever is shorter), hormone therapy, treatments with traditional Chinese medicine (for patients receiving treatments with traditional Chinese medicine with clear anti-tumor indications, for anti-tumor indications clearly specified in the package insert, one-week washout period prior to the first dose is acceptable), etc.;
  5. Use of radical radiotherapy (including radiotherapy for more than 25% of the bone marrow) within 4 weeks before the first dose; brachytherapy (e.g. radioactive particle implantation) within 60 days prior to the first dose; palliative radiotherapy for bone metastases within 1 week before the first dose;
  6. Previous use of anti (PD-1), anti-PD-L1, anti-PD-L2 or CTLA-4 antibody or any other antibody acting on T cell co-stimulatory or checkpoint pathways
