Clinical Trial Summary

This study is a prospective open-label, single-arm, single-center clinical study. Patients with neuroendocrine carcinoma who had not previously received standard therapy were enrolled in this study once they have signed the informed consent form (ICF) and been identified as eligible in screening. This clinical trial evaluates the efficacy and safety of surufatinib and serplulimab combined with standard chemotherapy (Platinum/Etoposide) in neuroendocrine carcinoma.

5. Have at least one measurable lesion according to RECIST v1.1;

6. ECOG performance status: 0-1;

8. For evidence of sufficient organ functions, the subjects shall meet the following laboratory parameters: 1) Absolute neutrophil count (ANC) = 1.5 x 109/L without use of granulocyte colony stimulating factor in recent 14 days; 2) Platelet count = 100 × 109/L without blood transfusion in recent 14 days; 3) Hemoglobin > 9 g/dL without blood transfusion or erythropoietin use in recent 14 days; 4) Total bilirubin = 1.5 × upper limit of normal (ULN); or total bilirubin > ULN, direct bilirubin = ULN; 5) Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) = 2.5 × ULN (ALT or AST = 5 × ULN for patients with liver metastasis); 6) Blood creatinine = 1.5 × ULN and creatinine clearance (calculated by Cockcroft- Gault formula) = 50 mL/min;

2. With known allergic reactions to the drugs in this study;

3. Unable or unwilling to swallow Surufatinib or suffering from significant digestive system diseases that may interfere with absorption, metabolism, or excretion;

4. With clinically significant or uncontrolled heart diseases, including unstable angina, acute myocardial infarction within 6 months before the first dose, grade III/IV congestive heart failure (New York Heart Association), and uncontrolled arrhythmia (subjects with pacemakers or with atrial fibrillation but well controlled heart rate are allowed); With ECG changes or medical history considered clinically significant by the investigator; QTc interval > 450 ms for male or > 470 ms for female at screening;

5. With active ulcers, intestinal perforation, and intestinal obstruction;

10. Received systemic immunostimulant therapy within 4 weeks before the first dose;

11. Received any live vaccines or live attenuated vaccines within 4 weeks prior to the first dose or planned to be administered live vaccines or live attenuated vaccines during the study;

12. Pleural effusion, ascites, or pericardial effusion with obvious clinical symptoms that require drainage;
