Clinical Trials

Are you an adult with mild heart failure and a left bundle branch block? This study will test whether a type of pacemaker called a cardiac resynchronization device can help the heart pump more blood in people who have mild heart failure (HF) and left bundle branch block. In the study, participants will have a cardiac resynchronization device implanted. This study is located in Bethesda, Maryland.

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.
