Clinical Trials

Do you have coronary heart disease, and are you interested in helping researchers improve how they treat and prevent this condition? This study is exploring new risk factors that may allow for more people with heart disease to get approved for an implantable cardioverter defibrillator (ICD), a device that can detect and stop irregular heartbeats. To participate in this study, you must be 18 years old or older and already have or be eligible for an ICD. This study takes place in Buffalo, New York.

Do you or your child have dyslipidemia? This study is exploring how different diagnostic tests can help us understand how lipid disorders, including high blood cholesterol and high blood triglycerides, affect the body. Information from this study may help improve the way lipid disorders are diagnosed or treated in the future. Participants must be at least 2 years old. This study is located in Bethesda, Maryland.

Do you or your child have obesity and high blood cholesterol or triglycerides? This study is testing the use of a statin in young people to see whether early treatment of high blood cholesterol can affect the risk of developing plaque in blood vessels. Participants in this study must be age 10-17, have a body mass index (BMI) in the obese range, be fluent in English, and not be pregnant.

Do you or your child have dyslipidemia? This study is exploring how different diagnostic tests can help us understand how lipid disorders, including high blood cholesterol and high blood triglycerides, affect the body. Information from this study may help improve the way lipid disorders are diagnosed or treated in the future. Participants in this study must be at least 2 years old. The study is being conducted in Bethesda, Maryland.

Are you an adult who is healthy or has problems with the level of cholesterol or other lipids in the blood? This study is gathering information on the risk factors for very high or very low levels of lipids, or fats, in the blood. Researchers will collect participants’ demographic information, medical history, and blood samples. To participate in this study, you must be at least 18 years old. This study takes place in Dallas, Texas.

Do you or a loved one have pneumonia? This study will test whether combining two medicines to reduce inflammation of the airway and to keep it open may help prevent respiratory failure in people who have pneumonia. To participate in this study, you must be at least 18 years old and have severe pneumonia with low blood oxygen levels.

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.

Are you a healthy adult or someone with a history of lung infections such as pneumonia or bronchitis? This study aims to compare fluid and tissue samples from the nose and lungs of healthy adults with people who have a lung disease. Researchers hope to learn why some people are more susceptible to certain infections. This study is located at the NIH Clinical Center in Bethesda, Maryland.

Are you an adult with a diagnosed sleep phase disorder? This study aims to assess the sleep patterns and quality of sleep in people who have sleep phase disorders to determine how the disorders affect their circadian rhythms. To participate in this study, you must be at least 18 years old and have a sleep phase disorder, such as advanced sleep-wake phase syndrome or delayed sleep-wake phase syndrome. This study is located in Chicago, Illinois.

Does your child have overweight or obesity? This study is exploring the link between obesity and sleep deprivation in children. Researchers will test whether participants who do not get enough good quality sleep have trouble making healthy food choices. Participants in this study must be 8 to 12 years old and have overweight or obesity. This study takes place in Pittsburgh, Pennsylvania; and Providence, Rhode Island.
