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 is creating a large collection of blood, urine, stool, and heart tissue samples from 10,000 people with and without heart or metabolic conditions. The goal is to store these samples along with medical information to speed up future research into what causes these disea…

This study aims to collect medical data and biological samples (blood, urine, stool, and tissue) from up to 4,000 adults with known or suspected gastrointestinal diseases. Participants receive standard medical care at the NIH, and any extra samples or leftover tissue from procedu…

This study reviews medical records of 500 adults treated for benign or malignant pancreatic diseases since 2005. The goal is to understand how well different treatments worked over time. No new treatments are given—just careful analysis of past cases.

This study aims to find the genetic causes of primary aldosteronism, a condition where adrenal tumors cause high blood pressure, in Black individuals. Researchers will enroll 1150 participants, including those with difficult-to-control blood pressure or known primary aldosteronis…

This study tests a new communication tool called 'Let's Get REAL' that helps children and teens (ages 8-17) and their families talk together about stem cell transplant or cellular therapy decisions. The goal is to see if the tool is easy to use and helpful for families. About 60 …

This study aims to understand how the hormone insulin controls blood sugar in different people. Researchers will test a new procedure called the graded insulin suppression test (GIST) in 15 healthy volunteers and those at higher risk for type 2 diabetes. Participants receive medi…

This early-phase study looks at whether adding dapagliflozin, a diabetes drug, to standard chemotherapy changes insulin-related markers in the blood. It involves 20 women with early-stage HER2-negative breast cancer who also have high insulin levels. The goal is to gather safety …

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 looks at how fasting insulin and insulin resistance differ based on age, sex, race/ethnicity, body weight, and PCOS diagnosis. Researchers will analyze data from 150 adults to find patterns that may explain why some groups face higher metabolic risks. The goal is to be…

This early-stage trial is testing whether a one-week course of diazoxide can reduce the production of new fat in the liver. The study involves 25 adults with obesity, insulin resistance, and fatty liver disease. Participants will take either the drug or a placebo and undergo bloo…

This study looks at how the hormone insulin controls blood sugar and fat in healthy adults and those at risk for type 2 diabetes. Researchers will give participants a single dose of a drug called alpelisib, which blocks some of insulin's effects, to see if the liver can still mak…

This study looks at how antipsychotic drugs might cause metabolic problems in women by affecting how the brain responds to insulin. Researchers will give 15 healthy women a single dose of the antipsychotic olanzapine and insulin nasal spray, then use brain scans to see changes. T…
