Clinical Trials

Are you an adult with sleep apnea, overweight, or obesity, or do you just want to help research? This study is looking at how sleep apnea changes fat tissue in the body. The researchers will examine whether these changes in fat tissue may raise the risk of heart and blood vessel diseases. To participate in this study, you must be between 18 and 60 years old with obstructive sleep apnea and healthy without any chronic diseases. This study takes place in Rochester, Minnesota.

Does your child have overweight or obesity or just want to be in a study on sleep and eating habits? Overweight and obesity are common in children who do not get enough good quality sleep. This study aims to understand how sleep deficiency can affect a child’s ability to make good food choices. Researchers will ask participants to spend either 8 or 11 hours in bed and to keep track of their food choices. Participants in this study must be 8 to 12 years old. This study takes place in Pittsburgh, Pennsylvania and Providence, Rhode Island.

Have you or your child been diagnosed with a blood disorder? If so, you (or they) may be able to participate in a clinical study where researchers are studying a type of infusion using cord blood. Participants can be of any age but must have a blood disorder diagnosed by their doctor. The study is taking place in locations in Alabama, Arizona, California, Colorado, Delaware, Florida, Georgia, Illinois, Indiana, Kentucky, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nebraska, New York, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, Washington, Washington, D.C., West Virginia, and Wisconsin.

Do you or your child have an immunodeficiency, such as fewer T cells or NK cells? You can help researchers better understand how some types of immunodeficiencies are inherited. Participants in this study must be at least 6 months of age. This study is located at the NIH Clinical Center in Bethesda, Maryland.
