This is a Phase 2, open-label, multi-centre study of surufatinib in patients with low to intermediate grade (Grade 1 or Grade 2), well-differentiated neuroendocrine tumours (NETs).

Official Title

An Open-Label Phase 2 Study of Surufatinib in Patients With Neuroendocrine Tumours in Europe


This is a Phase 2, open-label, multi-centre study of surufatinib in patients with low- to intermediate-grade (Grade 1 or Grade 2), well-differentiated NETs.

The study will enroll 4 cohorts of varying NETs, as follows:

  • Cohort A - NET of lung origin
  • Cohort B - NET of small bowel origin
  • Cohort C - NET of non-small bowel, non-pancreas, and non-lung origin
  • Cohort D - NET of any origin (DDI substudy)

All patients will be treated with oral surufatinib 300 mg QD in treatment cycles of 28 days starting on Cycle 1 Day 1.
