Hyperprolactinemia

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 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 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 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 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…
