Neuroendocrine Tumors

The purpose of this study is to find out what effects an immunotherapy drug, called pembrolizumab, combined with a radioactive drug, called lutetium Lu 177 dotatate (Lutathera®) have on patients with Merkel cell carcinoma. Pembrolizumab works by helping patient's immune system to fight cancer. Lutathera works by killing cancer cells. Pembrolizumab is approved by the FDA to treat Merkel cell cancer and has caused some Merkel cell cancers to shrink and/or resolve. Lutathera is FDA-approved to treat some neuroendocrine tumors and has caused some patient's neuroendocrine tumors to shrink and allowed them to live longer, but it is not approved by the FDA to treat Merkel cell cancer. The combination of Lutathera and pembrolizumab to treat Merkel cell cancer is investigational, which means this combination is not approved by the FDA to treat Merkel cell cancer.

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.

This study aims to determine the safety, pharmacokinetics (PK) and recommended Phase 3 dose (RP3D) of RYZ101 in Part 1, and the safety, efficacy, and PK of RYZ101 compared with investigator-selected standard of care (SoC) therapy in Part 2 in subjects with inoperable, advanced, well-differentiated, somatostatin receptor expressing (SSTR+) gastroenteropancreatic neuroendocrine tumors (GEP-NETs) that have progressed following treatment with Lutetium 177-labelled somatostatin analogue (177Lu-SSA) therapy, such as 177Lu-DOTATATE or 177Lu-DOTATOC (177Lu-DOTATATE/TOC), or 177Lu-high affinity \[HA\]-DOTATATE.

This is a first in man study to determine if \[203Pb\]VMT-α-NET identifies neuroendocrine tumors with SPECT/CT. This is the first step to testing \[212Pb\]-based alpha radiation therapy in neuroendocrine therapy.

This is a study to evaluate the efficacy and safety of belzutifan monotherapy in participants with advanced pheochromocytoma/paraganglioma (PPGL), pancreatic neuroendocrine tumor (pNET), von Hippel-Lindau (VHL) Disease-Associated Tumors, Advanced Gastrointestinal Stromal Tumor (wt GIST), or Advanced Solid Tumors With hypoxia inducible factor-2 alpha (HIF-2α) related genetic alterations. The primary objective of the study is to evaluate the objective response rate (ORR) of belzutifan per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by blinded independent central review (BICR).

This phase III trial studies cabozantinib to see how well it works compared with placebo in treating patients with neuroendocrine or carcinoid tumors that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Cabozantinib is a chemotherapy drug known as a tyrosine kinase inhibitor, and it targets specific tyrosine kinase receptors, that when blocked, may slow tumor growth.

The purpose of this research study is to see if Abraxane and Gemcitabine given together will be effective in treating small cell cancer that has progressed after one line of treatment.
