Pancreatic neuroendocrine tumour metastatic

This is a phase I, open-label study to assess the safety and preliminary efficacy of Fulvestrant in combination with 177Lu-DOTATATE for advanced pNETs.

This phase I trial tests the safety, side effects, and best dose of sunitinib malate in combination with lutetium Lu 177 dotatate in treating patients with pancreatic neuroendocrine tumors. Sunitinib malate is in a class of medications called kinase inhibitors and a form of targeted therapy that blocks the action of abnormal proteins called VEGFRs that signal tumor cells to multiply. This helps stop or slow the spread of tumor cells. Radioactive drugs, such as lutetium Lu 177 dotatate, may carry radiation directly to tumor cells and not harm normal cells. It is also a form of targeted therapy because it works by attaching itself to specific molecules (receptors) on the surface of tumor cells, known as somatostatin receptors, so that radiation can be delivered directly to the tumor cells and kill them. Giving sunitinib malate and lutetium Lu 177 dotatate in combination may be safer and more effective in treating pancreatic neuroendocrine tumors than giving either drug alone.

Doctors and researchers leading this study hope to learn more about peptide receptor radionuclide therapy (PRRT) in combination with cytoreduction (surgically removing tumors). They hope to learn if combining PRRT in combination with cytoreduction would be more effective than cytoreduction alone. PRRT itself is approved by the U.S. Food and Drug Administration (FDA) for people with PanNETs however the combination with cytoreduction is considered experimental.
Your participation in this research will last about 2 years. The purpose of this research is to gather information on the safety and effectiveness of PRRT.
