Endogenous Cushing syndrome

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 study looks at two treatments for mild autonomous cortisol secretion (MACS), a condition where the body makes too much cortisol. Researchers want to see if removing the adrenal gland (surgery) or taking semaglutide (a weight-loss drug) better improves insulin resistance and …

This study tests a low dose of the drug osilodrostat in 15 adults with mild autonomous cortisol secretion (MACS), a condition where the body makes too much cortisol. The goal is to see if the drug is safe and can help balance cortisol levels. Participants will take the pill and b…

This study compares two medications, metyrapone and osilodrostat, in 150 adults with mild autonomous cortisol secretion (MACS). Participants receive one of the drugs, surgery, or watchful waiting. The goal is to see which drug better lowers cortisol and improves related health is…

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 whether a special PET/CT scan (68Ga-Pentixafor) is as good as the standard adrenal vein sampling (AVS) at identifying which adrenal gland is causing high blood pressure and excess cortisol. About 178 adults with both conditions will be randomly assigned to one te…

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 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 follows 521 patients who had adrenal gland surgery for primary aldosteronism, a condition causing high blood pressure. Researchers want to see how often the remaining adrenal gland fails to produce enough cortisol after surgery, especially in patients who also had extr…

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 tests a special radioactive tracer called [18F]FNP-59 to see if it can safely and clearly show cholesterol activity in the adrenal gland using PET scans. About 24 people will take part, including healthy volunteers and those with known adrenal problems. The goal is to …

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…
