Hyperpituitarism

This study follows 200 people with acromegaly who are using octreotide subcutaneous depot, a medication that helps control hormone levels. Researchers will monitor safety and effectiveness for up to two years in everyday clinical practice, not a controlled lab setting. The goal i…

This phase 3 trial tests a new long-acting version of the drug octreotide (Debio 4126) for people with acromegaly, a condition caused by too much growth hormone. The drug is given as a shot every 12 weeks, instead of the usual monthly injections. The study will compare it to a pl…

This study tests a new drug called Lu AG13909 in 18 adults with Cushing's disease, a rare condition where the body produces too much cortisol. The goal is to see if the drug can safely lower cortisol levels to normal. Participants will receive the drug through an IV or injection,…

This early-stage study tests an experimental pill called CRN04894 in 18 adults with Cushing's syndrome caused by too much ACTH hormone. The drug works by blocking the receptor that ACTH acts on, aiming to lower cortisol levels and control the disease. The main goals are to check …

This phase 2 trial tests whether adding ALXN2420 (a growth hormone blocker) to standard acromegaly treatment can lower IGF-1 levels more than placebo. About 60 adults with acromegaly who are already on a stable dose of somatostatin analogs will receive either ALXN2420 or placebo …

This study tests whether a higher dose of the drug cabergoline, taken for about 6 months, can achieve lasting remission in women with small prolactinomas (non-cancerous pituitary tumors that cause excess prolactin). 70 premenopausal women will be randomly assigned to either the h…

This Phase 1 trial tests the safety of a new drug called MAR002 in 45 healthy men. Participants receive either MAR002 or a placebo by injection. The goal is to see if it's safe and how the body processes it, before testing it in people with acromegaly.

This study tests whether cabergoline works better than bromocriptine for women with high prolactin levels. About 382 women aged 18-45 will take one of the two drugs for 14 weeks. The main goal is to see whose prolactin levels return to normal, along with checking ovulation, breas…

This study looks at how different doses of the drug cabergoline affect blood sugar control in people with prolactinoma, a type of pituitary tumor. Researchers will randomly assign 60 adults to different treatment strategies and measure their glucose levels after a sugar drink. Th…

This study looks at whether the drug Pasireotide LAR can reduce the risk of spine fractures in people with acromegaly better than another drug, Pegvisomant. Acromegaly is a condition where too much growth hormone weakens bones, leading to painful fractures. Researchers will follo…

This phase 2 trial tests seliciclib, an oral drug, in 13 adults with Cushing disease. The goal is to see if 4 weeks of treatment can lower high cortisol levels to normal or reduce them by at least half. Researchers will also monitor safety and check for changes in tumor size and …

This study tests whether a special PET scan (FET PET/CT) can better locate small pituitary tumors that cause Cushing disease. About 50 adults with confirmed Cushing disease who are scheduled for pituitary surgery will receive the scan before their operation. The goal is to see if…

This study compares advanced PET scans (68Ga-DOTATATE and F-DOPA) with standard imaging to locate hidden tumors causing ectopic Cushing syndrome. About 80 adults with this condition will undergo multiple scans over time. The goal is to see which scan or combination best finds the…

This study aims to improve how doctors diagnose Cushing's syndrome, a condition caused by too much cortisol. Researchers will test the accuracy of the desmopressin stimulation test in 140 people aged 18-70 who have or may have Cushing's, plus healthy volunteers. Participants will…

This study tests whether a special PET scan, combined with a drug called desmopressin, can find tiny pituitary tumors that standard MRI scans miss in people with Cushing's disease. About 22 participants will receive the drug and a radioactive tracer, then undergo imaging. The goa…

This study is testing whether a special PET scan using [18F]FET can better locate small pituitary tumors that cause Cushing's disease. Standard MRI misses these tumors in up to 30% of cases. Researchers will compare PET results with MRI and surgical findings in 20 adults to see i…

This early study tests a special PET/MRI scan using a radioactive tracer called FET to find small pituitary tumors that don't show up on regular MRI. The goal is to improve detection of these hormone-producing tumors in 5 adults with confirmed biochemical disease. If the scan wor…

This study tests a new ultrasound method to help surgeons find pituitary tumors during surgery. Researchers will compare ultrasound images with MRI scans to see if the new technique can better identify tumors in people with Cushing's disease and other pituitary tumors. About 110 …

This study looks at how people recover from Cushing syndrome after surgery. Researchers want to understand what affects recovery and whether using a MUSE biofeedback headband can help ease withdrawal symptoms. The study will include 700 adults who are planning to have curative su…

This study at the National Institutes of Health is looking at 1,000 adults with known or suspected hormone gland (endocrine) disorders. The goal is to better understand these conditions and help train doctors. Participants may receive tests, treatments, or surgery as part of thei…

This study enrolls up to 15,000 children with known or suspected endocrine or metabolic disorders, along with their family members. Researchers will collect medical records, blood, saliva, and other samples to identify genetic changes linked to these conditions. The goal is to be…

This study aims to uncover the genetic causes of pituitary and hypothalamic tumors in children. Researchers will collect blood and tumor samples from up to 2,000 participants to analyze DNA and look for inherited patterns. The study also trains doctors and tests new MRI technique…

This study looks at the long-term health of people who were cured of Cushing disease before age 21. Researchers want to understand how past high cortisol levels affect the body and mind years later. Participants will complete surveys and have check-ups every 5 years. The goal is …

This study aims to find new genes that cause pituitary tumors, including those that lead to acromegaly (gigantism) and prolactinomas. Researchers will collect blood and tissue samples from up to 10,000 people with these tumors and their family members. By analyzing DNA, they hope…

This study enrolls adults with known or suspected endocrine (hormone gland) disorders, such as diabetes or thyroid disease, to help researchers learn more about these conditions. Participants will undergo medical exams, blood and imaging tests, and possibly genetic testing. The m…

This study is testing a tool called B-COMPASS that uses a 22-question survey to predict whether people will follow their prescribed treatments. Researchers will enroll 3100 adults with cardiovascular, endocrine, immune, nerve, cancer, or rare diseases across Europe. The goal is t…

This study is not testing a new treatment. Instead, it follows 300 people aged 14 and older with Cushing's syndrome to collect data on their health before and after standard treatments like surgery, medication, or radiation. The goal is to build a registry that helps doctors unde…
