Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an Open-Label Phase I/II Study of daily cabozantinib plus lanreotide every 4 w eeks to treat advanced G1-2 gastroentero-pancreatic neuroendocrine tumor (GEP-NET) patients who failed to one line or more than one line of small molecule kinase inhibitor or well-differentiated (W-D) G3 GEP-NET who failed to one line of small molecule kinase inhibitor or chemotherapy.

Detailed Description

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

This is an Open-Label Phase I/II Study of daily cabozantinib plus lanreotide every 4 w eeks to treat advanced G1-2 gastroentero-pancreatic neuroendocrine tumor (GEP-NET) patients who failed to one line or more than one line of small molecule kinase inhibitor or well-differentiated (W-D) G3 GEP-NET who failed to one line of small molecule kinase inhibitor or chemotherapy. The primary objective of the study is to determine the maximal tolerated dose (MTD) of cabozantinib of this combinational regimen in the phase I study and the progression free survival in the phase II study. The secondary objectives are the objective response rate, overall survival, toxicities and biomarker analysis of this regimen.

Eligible patients will receive a combination of oral cabozantinib 40-60 mg/day and lanreotide 120mg deep subcutaneous injection (SC) in day 1 every 4 weeks. Four weeks is a cycle. The patients will continue to receive this regimen till disease progression, intolerable adverse events (after dose modification), death, or withdrawal by patients' or principle investigator's decision.
