NCT07357623

Brief Summary

The goal of this clinical trial is to investigate if chemotherapy works with surufatinib to treat pulmonary neuroendocrine tumors. It will also learn about the safety of this combination regimen. The main questions it aims to answer are: Does chemotherapy combined with surufatinib could bring more survival benefits (ie. higher response rate or longer survival time) for patients with pulmonary neuroendocrine tumors? Is this combination regimen safe? Researchers will compare chemotherapy plus surufatinib with surufatinib monotherapy to see if this combination regimen works to treat pulmonary neuroendocrine tumors. Participants will: Take chemotherapy(Etoposide+Carboplatin, EC or Capecitabine+Temozolomide, CAPTEM) plus surufatinib or surufatinib monotherapy every 3 or 4 weeks as a cycle. Visit the clinic once every cycle for checkups and tests. Tumor assessment is performed every 2 cycles. Treatment will continued until disease progression, death, intolerable toxicity, or withdrawn.

Eligibility Criteria

  • years old (including cut-off value), male or female;
  • Patients must have at least one measurable lesion (RECIST 1.1);
  • Histologically or cytologically confirmed pulmonary neuroendocrine tumor (typical or atypical carcinoid) \[at least one neuroendocrine immunohistochemistry marker (CD56, CgA, Syn) definitively positive on the basis of morphological features of neuroendocrine tumors\];
  • Patients who have not received systemic therapy in the past (Note: neoadjuvant or adjuvant chemotherapy is allowed in the early stage, and if disease progression/recurrence occurs ≥ 6 months after the end of neoadjuvant/adjuvant last therapy, it can also be included);
  • ECOG PS 0-1 (PS 0-2 for amputees);
  • Expected survival ≥ 12 weeks;
  • Blood test (without blood transfusion within 14 days) 1) Absolute neutrophil value ≥1.5×109/L, platelet ≥ 100×109/L, hemoglobin ≥9g/dL; 2) Liver function tests (AST and ALT≤2.5×ULN, total bilirubin≤1.5×ULN; AST and ALT ≤5×ULN) if liver metastases are present; 3) Renal function (serum creatinine ≤1.5×ULN, creatinine clearance (CCr) ≥60ml/min);
