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.

Are you an adult who has PAD and difficulty walking? This study is testing whether a medicine that helps the body make more white blood cells can, along with walking exercise, improve symptoms and blood flow in people who have PAD. To participate in this study, you must be between 21 and 80 years old and have PAD. Women must not be pregnant and must use birth control or have been surgically sterilized if they still have menstrual periods. This study is located in Atlanta, Georgia.
