Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

273 patients will be randomly assigned (in 2:1 ratio) to the Surufatinib or Placebo treatment group based on interactive web response system（IWRS).The patients will receive continuous oral treatment, every 28-day treatment cycle until progression of disease occurs, intolerable toxicity or other protocol specified end-o-treatment criteria is met. The tumor should be assessed every 8 weeks (+/-3 days) within the first year and every 12 weeks (+/-3 days) after the patient has been treated for one year.

A Blinded Independent Image Review Committee (BIIRC) will subsequently provide a central review of the oncologic imaging materials from the patients.

An independent Data Monitoring Committee (IDMC) will be assembled to monitor safety and efficacy data, and evaluate interim analysis. If the interim analysis demonstrates overwhelming efficacy of the treatment arm with respect to PFS (primary endpoint) versus control arm, IDMC could recommend terminating and to unblinding the study and Surufatinib will be offered to the control arm patients who are still on treatment until disease progression or intolerable toxicity.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Adequately understand the study and voluntarily sign the Informed Consent Form;
2. Be at least 18 years old;
3. Based on central pathology review results，patients have a confirmed histologically pathology diagnosis of low- or intermediate grade (G1 or G2) advanced (unresectable or distant metastatic) extrapancreatic NETs with origins including, but not limited to, the lung, thymus, the gastrointestinal tract (stomach, duodenum, liver, jejunum, ileum, colon, cecum, appendix, rectum) and unknown origin etc. For Gastrointestinal neuroendocrine tumors (GI-NETs), G1 is defined as \< 2 mitoses /10 high-power field［HPF］and/or \<3% Ki-67 index; G2 is defined as 2-20/10 HPF and/or 3-20% Ki-67 index; for NETs originating from the lung and thymus gland, G1 is defined as \<2 mitoses/10 HPF and no necrosis; G2 is defined as 2-10/10 HPF and/or foci of necrosis. NETs from origin other than GI-NET, lung and thymus, or from unknown origins should be graded according to the GI-NET grading criteria. If the mitotic ratio and Ki-67 index correspond to different grade, the higher grade should be used to assign classification.
4. Have previously progressed on no more than two types of systemic anti-tumor therapy, including long-acting somatostatin analogs (SSAs), interferon, PRRT(peptide receptor radionuclide therapy), mTOR inhibitors or chemotherapy(chemotherapies were considered as one kind of regimen, regardless of medications and cycles); patients who are unable or unwilling to receive such treatments are also eligible;
5. Patients must have radiological documentation of progression of disease within 12 months prior to randomization.
6. Have measurable lesions (according to RECIST 1.1);
7. Absolute neutrophil count (ANC) of ≥1.5×109/L, platelet count of ≥100×109/L, and hemoglobin ≥9 g/dL;
8. Serum total bilirubin \<1.5 times the upper limit of normal (ULN);
9. Patients who do not have liver metastasis, with alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels ≤ 2.5 times the ULN; and who do have liver metastasis, with ALT and AST ≤ 5 times ULN.
10. Serum creatinine \<1.5 times ULN and creatinine clearance ≥60 ml/min;
11. International Normalized Ratio (INR) ≤1.5 ULN and activated partial thromboplastin time (APTT) ≤1.5 ULN.
12. Have a performance status (PS) of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) scale;
13. Have expected survival of more than 12 weeks;
14. Male or females patients with reproductive potential must agree to use an effective contraceptive method, for example, double-barrier device, condom, oral or injected birth control medication or intrauterine device, during the study and within 90 days after study treatment discontinuation. All female patients are considered to be fertile, unless the patient had natural menopause or artificial menopause or sterilization (such as hysterectomy, bilateral oophorectomy or ovarian irradiation).
