Clinical Trials

Are you or your child at least 13 years old and have sickle cell disease? In this stidy, researchers are trying to find out if a new medication improves the success of a blood stem cell transplant. People 13 years old or older who are eligible for a blood stem cell transplant to treat sickle cell disease may be able to participate. Healthy family members over age 13 who are matched to transplant recipients are also needed to donate blood for the study. This study is taking place at the National Institutes of Health Clinical Center in Bethesda, Maryland.

Are you in need of a heart or lung transplant or have you had one in the past 3 months? Have you undergone a lung or heart transplant in the past 3 months or are you a candidate for heart or lung transplant? Some people with advanced heart and lung disease have heart and lung transplants but these new organs are often rejected. When this happens, patients must have repeated biopsies, which are invasive and expensive. Researchers in this clinical study want to see if a blood test can predict organ rejection and take the place of biopsies. To participate, you must be 18 to 80 years old and be a candidate for heart or lung transplant or have had a heart or lung transplant no more than three months ago. The study is taking place in Bethesda, Maryland, at the NIH Clinical Center, as well as in Baltimore, Maryland, and Falls Church, Virginia.

Do you have high blood pressure? If so, you may be able to participate in a clinical research study. Researchers are testing a home-based blood pressure monitoring program that provides health education, guidance, monitoring, and patient coaching to people who live in rural areas. You must be at least 18 years old to participate and be taking medication for high blood pressure. The study is taking place in Pittsburgh, Pennsylvania.

The investigators propose to study the relationship between right ventricle (RV) steatosis and RV function, exercise capacity, and outcomes in humans with pulmonary arterial hypertension (PAH) and to identify potential drivers of lipid accumulation.

The purpose of this project is to test sleep reactivity as an independent cause of Shift Work Disorder (SWD).

This study is designed to assess how healthy premenopausal women respond to different patterns of sleep loss at different times in the menstrual cycle.

The purpose of this study is to investigate: 1) whether statins reduce endothelial inflammation and pro-thrombotic conditions in sleep apnea, including in patients adherent to CPAP (Aim 1); and 2) whether statins reduce endothelial inflammation and pro-thrombotic conditions by improving endothelial cholesterol metabolism and trafficking in sleep apnea.

Are you a former smoker with COPD? Researchers are studying whether taking aspirin can help with COPD symptoms. Participants must be at least 40 years old, be diagnosed with COPD, and have a history of smoking at least 10 packs of cigarettes a year. The study is taking place in Baltimore, Maryland.

Do you have heart failure and live near Massachusetts General Hospital in Boston, Massachusetts? Researchers are testing whether an online program helps lower the number of times patients with heart failure return to the hospital. You may be able to participate if you are at least 18 years old, have heart failure, and live within 30 miles of Massachusetts General Hospital in Boston.

Are you a parent of a child in kindergarten to 5th grade? Or do you lead teachers who teach children in these grades? Researchers are testing if active learning can get children to move more. Active learning blends physical activity into school lessons. The study is taking place in Houston, Texas.
