Exclusion criteria
Exclusion criteria: 1. Has an AE due to previous antitumor therapy that has not recovered to CTCAE grade =1, except alopecia and peripheral neurotoxicity with CTCAE grade =2 caused by platinum chemotherapy 2. Major surgery within previous 4 weeks or radiation therapy within 2 weeks prior to the start of treatment (prior palliative radiotherapy for metastatic lesions is permitted if there is at least 1 measurable lesion that has not been irradiated) 3. Prior VEGF/VEGFR-targeted therapy, including, but not limited to sunitinib, axitinib, and cabozantinib 4. Has uncontrollable hypertension, defined as systolic blood pressure of =140 mmHg and/or diastolic blood pressure of =90 mmHg, despite antihypertensive medication 5. Prothrombin time (PT)/International normalized ratio (INR) of >1.5 or activated partial thromboplastin time (aPTT) of >1.5×ULN (for patients on Coumadin or Coumadin-like products) 6. Has gastrointestinal disease or condition within 6 months prior to first dose that investigators suspect may affect drug absorption, including, but not limited to, active gastric and duodenal ulcers, ulcerative colitis and other digestive disease, gastrointestinal tumor with active bleeding, or other gastrointestinal conditions that could, in the investigators' judgment, result in bleeding or perforation 7. Has a history or presence of a serious hemorrhage (>30 mL within 3 months) or hemoptysis (>5 mL of blood within 4 weeks) within 6 months of first dose of study drug 8. Has clinically significant cardiovascular disease, including, but not limited to, acute myocardial infarction within 6 months prior to enrollment, severe/unstable angina pectoris or coronary artery bypass grafting, congestive heart failure of =2 according to the New York Heart Association classification, ventricular arrhythmia that needs drug treatment, and left ventricular ejection fraction (LVEF) of <50% 9.

Has a high risk of bleeding at screening due to tumor invasion into major vessels, such as pulmonary artery, the superior vena cava, or the inferior vena cava, as determined by investigators 13. Has arterial thrombosis or deep venous thrombosis within 6 months prior to first dosing, or thromboembolic events (including stroke and/or transient ischemic attack) within 6 months prior to the first dose of study drug 14. Use of strong or moderate inducers or inhibitors of CYP3A4 within 2 weeks before the first dose of surufatinib 15. For Cohort D, use of medications that are known substrates, inhibitors, or inducers of CYP3A or substrates of P-gp or BCRP within 3 weeks before the first dose of the drug cocktail 16. Prior history of other cancers, except those treated with curative intent for in situ non-melanoma skin cancer, breast or cervical cancer, or those treated with curative intent and no evidence of disease in the last 5 years prior to enrollment in the study 17. Has a clinically meaningful ongoing infection (eg, requiring intravenous treatment with anti-infective therapy) a. See Appendix 8 (Section 15) of the Protocol for procedures specific
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the antitumor activity of surufatinib in patients with low- to intermediate-grade (Grade 1 or Grade 2), well differentiated neuroendocrine tumors (NETs);Secondary Objective: - To characterise the PK of surufatinib in patients with NET - To evaluate the effect of surufatinib on cardiac repolarisation, as detected by changes in ECG corrected QTc, and the potential relationship with surufatinib plasma concentrations - To further characterise the antitumour activity of surufatinib in patients with NET - Cohort D only: To evaluate the effects of repeat dosing of surufatinib on the single-dose PK of cytochrome P450 (CYP)3A4, P glycoprotein (P gp), and breast cancer resistance protein (BCRP) substrates in patients with NET;Primary end point(s): Disease Control Rate (DCR) at 6 months;Timepoint(s) of evaluation of this end point: 6 months | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Observed plasma concentrations, estimated population PK, and exposure parameters of surufatinib - QTc and plasma concentrations of surufatinib at specified time points - Additional efficacy endpoints • Objective Response Rate (ORR) • Time to Response (TTR) • Duration of Response (DoR) • Progressive-Free Survival (PFS) - Cohort D only: Exposure parameters of CYP3A4, P-gp, and BCRP substrates - Safety assessments include: • Frequency and severity of AEs • Physical examination findings • Vital signs • Laboratory tests • ECG • Echocardiograms/MUGA;Timepoint(s) of evaluation of this end point: PK Plasma Sampling: Day (-1 & -2) & at specific timepoints as per Schedule of Events (SOE) ECG for QTc Evaluation: At pre & post-dose on Cycle 1 Day 1 and Cycle 1 Day 15 (+1 week) at specific time points given in SOE ORR: Time to attain best overall response or CR or PR per RECIST Version 1.1 TTR: Time between the start date of study drug until first documented response (CR or PR) according to RECIST Version 1.1 DoR: Timepoint at which the objective response reaches CR or PR, whichever comes first, until the occurrence of PD or death PFS: Time from the start of study drug to date of objective disease progression as defined by RECIST Version 1.1 or death, whichever comes first. Echocardiogram/MUGA: At screening, Every 12 weeks (±7 days) after the first dose AEs, SAEs: Screening, EOT | — |
