Clinical Trials

Are you an adult who does not have high blood pressure and is interested in research? This study will investigate how the brain regulates the body’s response to stress and how infection with HIV or pre-hypertension affects regulation. Your heart and brain activity will be measured while you are at rest, during a mentally stressful task, and while you feel angry. The study will also test whether a breathing exercise improves regulation. People with and without HIV and pre-hypertension will be included. To participate in this study, you must be between 21 and 65 years old and not have high blood pressure. This study is located in Miami, Florida.

Have you been diagnosed with LAM? This study is trying to understand the genes and proteins that are responsible for causing lung damage in patients with LAM. To participate in this study, you must be between 16 and 99 years old and diagnosed with LAM. This study is located in Bethesda, Maryland.

Are you an adult female who has been diagnosed with LAM? This study is examining which delivery method of albuterol—inhaled or nebulizer—is better at improving lung function in adult women who have LAM. This study is located in Bethesda, Maryland.

Do you have LAM and would be willing to help research? This study aims to identify the right dose of sirolimus to treat people who have LAM. To participate in this study, you must be female, between 18 and 90 years old, and diagnosed with LAM. This study is located in Bethesda, Maryland.

Are you an adult woman who would like to help develop methods to prevent the worsening of LAM? This study aims to discover whether earlier and longer treatment with a lower dose of sirolimus can help prevent LAM from getting worse over time. To participate in this study, you must be female, be at least 18 years old, and have been diagnosed with LAM. This study is located in Atlanta, Georgia; Boston, Massachusetts; Chicago, Illinois; Cincinnati, Ohio; Denver, Colorado; Nashville, Tennessee; Palo Alto, California; Philadelphia, Pennsylvania; and Seattle, Washington.

Do you or someone in your family have a lymphatic disorder such as LAM? This study is looking at the relationship between lymphatic disorders and gene variations found in the lungs, blood, and other parts of the body. Researchers hope this will improve our understanding of these types of disorders and how genetic factors affect them. Participants must be between 2 and 90 years old and either have a lymphatic disorder or be a relative of someone who does. This study is located at the NIH Clinical Center in Bethesda, Maryland.

Do you have tuberous sclerosis and want to help researchers better understand the disease? This study is investigating what causes multiple skin tumors to develop in people with tuberous sclerosis. To participate in the study, you must be at least 18 years old. This study is located at the NIH Clinical Center in Bethesda, Maryland.

Do you have metabolic syndrome? This trial is testing whether low-intensity exercise or high-intensity exercise works best to lower the risk of heart and blood vessel diseases in people who have metabolic syndrome and are taking a medicine called metformin to treat high blood sugar levels. To participate in this study, you must be between 40 and 80 years old and diagnosed with metabolic syndrome but not type 2 diabetes. This study takes place in New Brunswick, New Jersey.

Do you or your child have overweight or obesity? This study aims to find effective ways to prevent and treat obesity and metabolic syndrome in African American communities. The study will test the effectiveness of a family-based comprehensive health and fitness programs involving community health workers. Participants must be 12 years old or older and African American and have overweight or obesity. This study takes place in Charleston, South Carolina.

Does your child have higher triglyceride levels but normal cholesterol levels? This study is testing whether a protein supplement called carnitine can help prevent blood vessel stiffness in teenagers who have metabolic syndrome or other risk factors for heart and blood vessel diseases. Participants in this study must be between 13 and 19 years old and have moderate to high blood triglyceride levels but normal blood cholesterol levels. This study takes place in Houston, Texas.
