Sympathetic nervous system disorder

This phase 2 trial is testing a drug called ONC206 in 90 people with advanced pheochromocytoma or paraganglioma, rare tumors of the adrenal glands. Participants must have tumors that cannot be removed by surgery and have not responded to or cannot have standard treatments. The st…

This study tests a radioactive drug called I-MIBG in people with resistant neuroblastoma or related tumors (pheochromocytoma and paraganglioma). The drug is designed to deliver radiation directly to cancer cells. Researchers want to see if it can shrink tumors and how safe it is.…

This expanded access program provides 131 I-MIBG therapy for children and young adults with refractory or relapsed neuroblastoma, a cancer that hasn't responded to standard treatments. The therapy uses a radioactive compound that is taken up by cancer cells, delivering radiation …

This trial tests whether an injected tracer called HED, seen on PET/CT or MRI scans, can help diagnose diseases of the sympathetic nervous system, the part of the body that controls automatic responses like heart rate and blood pressure. Researchers will scan 500 adults who have …

This study is a large registry that collects health information and leftover tumor or blood samples from up to 75,000 children and young adults with cancer. The goal is to track outcomes and gather data to help doctors find better ways to treat and care for these patients over ti…

This pilot study looks at how belzutifan, a drug already used for some tumors, changes the production of adrenaline-like hormones in people with pheochromocytoma and paraganglioma (PPGL). Over 5 days, researchers measure key substances in the hormone-making process to see if belz…

This study aims to bring molecular markers into routine care for patients with rare adrenal cancers. Researchers will collect blood, urine, and tumor samples from 450 patients before and after surgery to see if these markers can guide treatment decisions. The goal is to make thes…

This study looks at why people with COPD may have overactive nerve signals that increase heart rate and narrow blood vessels. Researchers will measure nerve activity, breathing, and inflammation in 135 adults with COPD. The goal is to better understand the causes, not to test a n…

This study looks at how blood flow and the nervous system adapt early in aging women. Researchers will measure forearm blood flow in 64 women aged 18-70. The goal is to better understand these changes, not to test a treatment.
