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…

Researchers are testing a block-and-replace strategy for people with endogenous Cushing syndrome, a condition where the body makes too much cortisol. Participants receive osilodrostat, a drug that lowers cortisol production, along with a replacement glucocorticoid called methylpr…

This study compares a new, less invasive procedure called EUS-RFA to standard surgery for treating left-sided adrenal tumors that cause high blood pressure and other hormone-related issues. About 60 participants will receive the new procedure, which uses a thin tube inserted thro…

This study tests a drug called osilodrostat in children aged 2 to 17 with Cushing's syndrome, a condition where the body makes too much cortisol. The goal is to see how the drug is processed, how well it works, and if it is safe. Only 12 children will take part, and they must wei…

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 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 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 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 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 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 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 will check how common a condition called hypercortisolism (too much of the stress hormone cortisol) is in people with type 2 diabetes that is hard to control despite standard treatments. Researchers will also see if cortisol levels in saliva are linked to blood sugar c…

This study investigates whether proteins released by muscles, called myokines, can serve as early warning signs or even causes of muscle loss (sarcopenia) in people with metabolic or endocrine conditions like diabetes, obesity, and Cushing syndrome. Researchers will measure myoki…

This study looks at how common fatty liver disease is in people with Cushing's syndrome, a rare condition caused by too much cortisol. Using MRI and FibroScan, researchers will measure liver fat at diagnosis and again one year after cortisol levels return to normal. The goal is t…

This study aims to learn more about how adrenal tumors form and to test new treatment options for adrenal cancer. Researchers will study up to 500 adults who have an adrenal tumor seen on imaging. The goal is to improve understanding and find better ways to treat these tumors.

This study tests a new, radiation-free ultrasound technology called REMS to measure bone density in children aged 5 to 18 who have conditions that weaken bones, such as brittle bone disease or osteoporosis. The goal is to see if REMS can work as well as the standard X-ray method …

This study is creating a large database to collect information on people with rare diseases like amyloidosis, sarcoidosis, and Gaucher disease. Researchers will track patients' health over time, including their symptoms, treatments, and outcomes. The goal is to improve diagnosis …

This study is building a large group of 600 adults with various adrenal diseases, like Cushing's syndrome and adrenal tumors. Researchers will track their standard treatments (surgery, radiation, or medication) and outcomes. The goal is to learn more about these conditions, impro…

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…

This study is testing a new, minimally invasive brain stimulation technique for people with cerebellar cognitive affective syndrome (CCAS), a condition that causes problems with thinking, mood, and movement. The researchers are enrolling 200 participants with Cushing's syndrome-r…
