Clinical Trials

Do you or your child have a lung disease? This study will investigate the genes involved in the breathing process and in the development of lung diseases such as asthma or sarcoidosis to improve understanding of the role they play. To participate in this study, you or your child must be between 2 and 90 years old. This study is located in Bethesda, Maryland, at the NIH Clinical Center.

Do you have cystic fibrosis and are you eligible for a lung transplant? This study is interested in learning more about the presence and location of certain bacteria in the lungs of people who have cystic fibrosis by examining lungs that have been removed from patients who have cystic fibrosis who are undergoing a lung transplant. To participate in this study, you must be at least 18 years old, have been diagnosed with cystic fibrosis, be eligible for a lung transplant, and have tried all other available treatments without success. This study is located in Minneapolis, Minnesota.

Do you want to participate in a study with your child who has cystic fibrosis? This study is exploring computer models to compare cell samples from the noses of people who have cystic fibrosis, their parents, and other healthy individuals in hopes of better predicting how patients will respond to medicine. These computer models may allow medicines to be developed more rapidly and better predict who will respond to a certain cystic fibrosis treatment. To participate in this study, you must fall into one of the following groups: (1) have cystic fibrosis and be at least 12 years old, (2) be the biological parent of a cystic fibrosis patient enrolled in the study and be at least 18 years old, or (3) have no history of lung disease and be at least 18 years old. This study is located in Pittsburgh, Pennsylvania.

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.

The purpose of the research is to understand structural plaque abnormalities that make a carotid plaque unstable and brake off (embolize) which would help to predict and treat individuals who are likely to suffer not only classic episodic major strokes but also cognitive impairment.

The goal of this work is to develop and test a noninvasive ultrasound-based imaging technology to better identify patients at high risk of stroke so that appropriate and timely intervention may be administered to prevent it.

Are you an adult with carotid artery stenosis (CAS)? Researchers in this study want to learn more about the plaque that causes atherosclerosis in patients with carotid artery stenosis. To be in the study, you must be at least 18 years old and will undergo a carotid positron emission tomography (PET)/magnetic resonance imaging exam so researchers can lean more on the new PET imaging approach for risk prediction in these patients. The study is taking place Saint Louis, Missouri, and in Los Angeles, California.

Adults with stroke-related disability spend more time sedentary than adults without stroke-related disability, which places them at risk for poor cardiovascular health outcomes. Few interventions are designed to reduce post-stroke sedentary time.

The purpose of this research is to test whether the teleABLE (Activating Behavior for Lasting Engagement) Intervention is feasible and acceptable to adults within the first 12 months post-stroke. The hypothesis is that teleABLE can be feasibly delivered using videoconferencing within the first 12 months post-stroke. 10 participants will complete assessments and activity monitoring (activPAL micro3) at 0 (baseline) and 8 (post-intervention)-weeks. Participants will complete 12 sessions of the teleABLE intervention.

Findings from this study will be used to guide the intervention protocol in the planned next phase of this research.

Are you an adult who has uncontrolled high blood pressure? This study will see whether an early notification system for health professionals can help manage patients’ high blood pressure, especially among those who have had a stroke or have an increased risk of stroke. To participate in this study, you must be between 18 and 85 years old and have high blood pressure that is not controlled by medicine and lifestyle changes. This study is enrolling native English, Spanish, or Hmong speakers. The study is located in Minneapolis, Minnesota.
