Cushing syndrome

This phase 2 trial tests clofutriben, a drug that lowers cortisol, in 1500 adults with hard-to-control type 2 diabetes and signs of high cortisol. Participants receive either clofutriben or a placebo daily for 24 weeks. The study measures changes in blood sugar and cortisol level…

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 phase 2 study tests a radioactive tracer called [68Ga]Ga-PentixaFor to see if it can better identify adrenal tumors that produce excess hormones like aldosterone or cortisol. About 80 adults with known adrenal tumors and high hormone levels will receive the tracer before a P…

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 type of PET scan using a tracer called 68Ga-Pentixafor to help doctors tell apart the two main types of Cushing's syndrome (ACTH-dependent vs. ACTH-independent) and find the source of the problem. Researchers will enroll 160 adults with suspected or confirm…

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 observational study will measure salivary cortisol in 220 healthy adults and people with Cushing's syndrome or adrenal insufficiency. The goal is to establish normal reference ranges and find the best cut-off values for diagnosis. Researchers will compare two lab methods to …

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 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 …
