Clinical Trials

Are you 65 years old or older, and do you have severe primary mitral regurgitation? This condition — also called degenerative mitral regurgitation — happens when there is a problem with the mitral valve itself or its supporting tissue, leading to a leaky valve. This study is comparing the safety and effectiveness of two different ways of repairing the mitral valve: transcatheter edge-to-edge repair and surgical repair. To participate in this study, your healthcare provider must determine that you are a candidate for both mitral valve transcatheter edge-to-edge repair and surgical repair. This study takes place in multiple locations across the United States and Canada.

Are you an adult of African descent who hasn’t had a recent transfusion and doesn’t have a known pyruvate kinase deficiency? This study investigates how the PKLR gene affects the function of red blood cells and contributes to sickle cell disease. The PKLR gene helps make a protein called pyruvate kinase that is necessary for red blood cells to function properly. To participate in this study, you must be between 18 and 80 years old, with or without sickle cell disease. This study takes place in Bethesda, Maryland.

Are you an adult with sickle cell disease? This study aims to understand how diet and eating behaviors affect the health of people with sickle cell disease. To participate, you must be 18 years old or older. This study takes place in Bethesda, Maryland.

Do you or your child have sickle cell disease and a relative willing to donate stem cells? This study is giving a second blood stem cell transplant to people with sickle cell disease who have had their disease return after one stem cell transplant. To participate in this study, you must be 4 years old or older, have sickle cell disease, and have had your disease return after receiving a blood stem cell transplant. You must also have a relative who is older than 2 years and can donate stem cells via a blood draw. This study takes place in Bethesda, Maryland.

Do you or your child have symptoms of a serious lung disease but no diagnosis? This study aims to develop new ways to diagnose primary ciliary dyskinesia (PCD) and primary immune deficiency (PID), two conditions that can have similar symptoms. Researchers will combine information from genetic testing, lung imaging, and lung function tests to diagnose ant tell the difference between these two conditions. Participants in this study must be 5 to 45 years old. This study is taking place at multiple locations in the United States and in Canada.

Do you have pulmonary hypertension or scleroderma? This study aims to understand how scleroderma, a skin condition, can raise the risk of pulmonary hypertension and heart failure. The study will also test whether treatments for pulmonary hypertension in people who do not have scleroderma are effective in people who have both pulmonary hypertension and scleroderma. To participate in this study, you must be at least 18 years old and must have either pulmonary hypertension or scleroderma. This study is located in Maryland.

This trial will compare time from randomization to failure of treatment or death from any cause of IST versus URD BMT when used as initial therapy to treat Severe Aplastic Anemia.

Do you have high blood pressure, and do you receive care at a community-based clinic in the South? This study will explore an intensive high blood pressure management approach at participating community-based clinics. The approach aims to lower participants’ systolic blood pressure to 120 mm Hg. To participate in this study, you must be at least 40 years old, understand English, and not be pregnant. The study is located in Louisiana, Alabama, and Mississippi.

Are you an adult with high blood pressure who receives medical care from a Federally Qualified Health Center (FQHC)? This study is testing intervention strategies to help people from underserved communities lower their blood pressure and prevent cardiovascular disease. To participate in this study, you must be 40 years old or older and have high blood pressure that puts you at risk for cardiovascular diseases such as stroke or heart failure. This study takes place in New Orleans, Louisiana, and Biloxi, Mississippi.
