Clinical Trials and Studies

Do you have low blood pressure due to primary autonomic failure or multiple system atrophy? Autonomic failure is caused by problems with a part of the nervous system called the autonomic nervous system. People with these conditions can suffer debilitating low blood pressure upon standing. This study is testing the use of compression garments to improve blood pressure in people with these conditions. To participate in this study, you must be between 40 and 80 years old and have low blood pressure when standing. This study takes place in Nashville, Tennessee.

Are you older than 40 and have a history of peripheral artery disease (PAD)? This study will examine whether the drug rivaroxaban improves symptoms associated with peripheral artery disease (PAD). To participate in this study, you must be at least 40 years old and have a history of PAD. This study takes place in Nashville, Tennessee.

Has your child been treated for an asthma attack with an oral corticosteroid medicine in the last 12 months? A study team will recruit 60 teens and young adults (between 12 and 21 years old) with persistent asthma who are at high risk for future exacerbation. This study examines the contribution of interleukin 1 beta (IL-1β), a protein that is involved in the inflammatory response, in asthma flare-ups. This study takes place in Chapel Hill, North Carolina.

Are you an adult with asthma, and do you want to help researchers understand how asthma may affect the brain health? This study is examining whether long-term asthma complications are associated with brain structure, function, or cognitive function. In people with asthma, allergens can induce airway inflammation, which activates several cell types that could negatively affect the brain over time. Results from this study may shed light on whether there is a connection between brain health and asthma. To participate in this study, you must be between 18 and 50 years old. This study takes place in Madison, Wisconsin.

Are you an adult with severe asthma who plans to have bronchial thermoplasty treatment? This study is using a new imaging technique, called optical coherence tomography, to examine the airways in people with asthma before and after a treatment called bronchial thermoplasty. This treatment is minimally invasive and reduces asthma symptoms by using heat to shrink smooth muscle within the lungs. To participate in this survey, you must be between 18 and 60 years old. This study takes place in Boston, Massachusetts.

Are you an adult with asthma who is being treated with therapeutic proteins or is interested in trying this treatment? This study investigates the use of a treatment using therapeutic proteins in people with asthma and seeks to determine whether its use can lower inflammation in patients. To participate in this study, you must be between 18 and 80 years old. This study takes place in San Francisco, California.

Are you an adult currently being treated for rhinosinusitis (nasal inflammation) who would like to support research into the condition? This study is collecting blood, secretion, and tissue samples from people undergoing procedures to treat long-term rhinosinusitis. Rhinosinusitis, another term for nasal inflammation, is common in people who have asthma. To participate in this study, you must be between 18 and 80 years old. This study takes place in San Francisco, California.

Are you interested in supporting research into safe and effective flu prevention for people with COPD? This study is testing whether the nasal spray flu vaccine is safe and effective in people who have COPD. To participate in this study, you must be at least 40 years old and either healthy or diagnosed with COPD. This study takes place in Chapel Hill, North Carolina.

Are you a 30- to 55-year-old smoker or non-smoker who would like to support better understanding of COPD risk factors? This study aims to find early signs of COPD in adults who have a high risk of this condition. Researchers will compare results from questionnaires, lung tests, and other tests in people who smoke and in people who do not smoke to look for factors that predict which people will develop COPD. To participate in this study, you must either currently smoke or have no history of smoking. This study takes place in multiple locations in the United States.

Have you or your child been diagnosed with cystic fibrosis, and would you like to support better diagnosis of lung infections? This study is exploring new ways to diagnose bacterial lung infections in people who have cystic fibrosis. The study will test whether analyzing a participant’s breath and sputum samples can help diagnose infections. Participants in this study must be at least 3 years old. This study is taking place in multiple locations in the United States.
