Summary
This trial is testing belzutifan, a medication given alone, in patients with advanced cancers that have specific genetic changes. The drug works by blocking a protein that helps cancer cells grow. Belzutifan showed significant response rates for both Von Hippel-Lindau disease-associated kidney cancers and other types of cancers.
Who is the study for?
This trial is for adults with certain advanced cancers like pheochromocytoma, paraganglioma, pancreatic neuroendocrine tumors, VHL-associated tumors, GIST or solid tumors with HIF-2α alterations. Participants must have a specific diagnosis for each cohort, controlled blood pressure, good organ function and not be pregnant or breastfeeding. They should not have other treatments recently and no major health issues that could affect the study.
What is being tested?
The trial tests belzutifan's effectiveness and safety on its own in treating various advanced cancers related to HIF-2α genetic changes. The main goal is to see how well the cancer responds to belzutifan according to standard response criteria reviewed by independent experts.
What are the potential side effects?
Possible side effects of belzutifan may include fatigue, nausea, anemia (low red blood cell count), hypoxia (low oxygen levels), high blood pressure and liver problems among others. Each person might experience these differently.

Other Research
Common treatments for Pancreatic Neuroendocrine Tumors (pNETs) include somatostatin analogs, mTOR inhibitors, and HIF-2α inhibitors. Somatostatin analogs, such as octreotide and lanreotide, work by inhibiting hormone secretion and tumor growth, providing symptom relief and slowing disease progression. mTOR inhibitors like everolimus target the mTOR pathway, which is involved in cell growth and proliferation, thereby reducing tumor growth.
HIF-2α inhibitors, such as belzutifan, target hypoxia-inducible factors that are often overexpressed in tumors, disrupting the tumor's ability to adapt to low oxygen conditions and inhibiting its growth. These treatments are crucial for pNET patients as they offer targeted approaches to manage tumor growth and associated symptoms, improving quality of life and potentially extending survival.
