Clinical Trials

Do you have symptoms of a lung disease (such as long-term wet cough, bronchiectasis, or recurrent pneumonia) with no genetic diagnosis? This study aims to develop new ways to diagnose primary ciliary dyskinesia (PCD) or 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 and tell the difference between these two conditions. Participants in this study must be 5 to 45 years old and must have symptoms of a serious lung disease but no diagnosis. This study is taking place at multiple locations in the United States and in Canada, including the NIH Clinical Center in Bethesda, Maryland.

Do you or your child have primary ciliary dyskinesia (PCD) or primary immune deficiency (PID)? This study aims to identify genes that cause these two conditions, which can have similar symptoms. The results from this study will help researchers find new ways to treat breathing and hearing problems caused by these two conditions in a cross-sectional cohort of patients with PCD and PID. 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 heart failure that is well controlled through medication and attending regular appointments with your healthcare provider? This clinical trial is testing a dietary supplement taken by mouth twice a day for five days to see if it can help patients with heart failure. You must be at least 18 years old to participate. The study is taking place in New Haven, Connecticut.

Do you have heart failure? In this clinical trial, researchers are using images of the heart and blood tests to learn more about Black and Hispanic patients with heart failure. You may be able to participate if you are at least 60 years old; of Black, Hispanic, or Caribbean origin; and have been diagnosed with heart failure. The study is taking place in locations in Connecticut, Massachusetts, and New York.

Are you an adult with heart failure and an implanted CardioMEMS pulmonary artery pressure (PAP) monitor? This study is investigating whether psychological stress can make the symptoms of heart failure worse. Participants of this study will have their blood pressure monitored and their blood drawn after undergoing mental stress in a controlled setting, within a laboratory. To participate in this study, you must be at least 18 years old. This study takes place in New Haven, Connecticut.

Do you have heart failure and need treatment with intravenous (IV) diuretics? This study is exploring the use of chloride supplementation in people with heart failure who require treatment with IV diuretics, which are used to help rid your body of excess water and salt. To participate in this study, you must have heart failure with signs of volume overload (rales, edema, elevated jugular venous pressure [JVP], or weight gain of at least 5 pounds) requiring treatment with IV diuretics. This study takes place in New Haven, Connecticut.
