Clinical Trials and Studies

Are you interested in helping researchers learn more about how inflammation and diseases of the blood vessels start? Diseases related to the immune system, blood clots, and blood vessels are interrelated. This study is trying to understand how these diseases start and what happens in the different organs in people with these diseases. To participate in this study, you or your child should be 5 years old or older and be healthy or have an autoimmune disease, or problems with blood clots or blood vessels. This study is in Bethesda, Maryland.

Do you have a high-risk pregnancy? This study will investigate the use of a non-invasive scan called fetal magnetocardiography to detect potential problems in the fetus in five high-risk pregnancy conditions associated with stillbirth. The scan is normally used to look at fetal heart rhythms. To participate in this study, you must be at least 18 years old and pregnant with one of the following: having a stillbirth in a previous pregnancy, carrying identical twins, or having a fetus that has been diagnosed with major congenital heart disease, fetal hydrops, or fetal gastroschisis. This study takes place in Madison and Milwaukee, Wisconsin.

Are you a woman who is postmenopausal or a man older than 65? This study will investigate the effects of oral progesterone for older women and testosterone for older men on QT intervals. QT intervals that are increased by medicine can lead to dangerous heart rhythm problems. Researchers hope to learn more about why this happens and how to deliver safer doses. This study is located in Indianapolis, Indiana.

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.

The purpose of this trial is to evaluate if augmenting a usual audit and feedback implementation approach with telehealth-enabled support improves coordinated spontaneous awakening/breathing trials and patient outcomes for mechanically ventilated patients.

Data from a randomized clinical trial are urgently needed to determine the effect of ketamine versus etomidate on cardiovascular complications and clinical outcomes of emergency tracheal intubation.

Has your child suffered from a cardiac or respiratory arrest, major trauma, or respiratory failure that occurred outside the hospital? Has your child suffered from a cardiac or respiratory arrest, major trauma, or respiratory failure that occurred outside the hospital? In other words, did your child ever stop breathing or need CPR outside the hospital? Your child may have required treatment to keep their airway open, and this trial will compare the different strategies used in airway management in children who receive life-saving care initiated or continued by EMS personnel in a real world setting. The study is being conducted in many sites across the United States all following the same protocol.

Have you or a family member experienced acute respiratory failure (ARF)? Have you or a family member experienced acute respiratory failure (ARF)? In other words, did you or a family member have severe difficulty in breathing that led to admission to an acute ward or ICU in the hospital? This study will administer three surveys over 6 months to understand if expectations about recovery after experiencing ARF are related to the mental health of survivors or caregivers. To participate in this study, you must be 18 years old or older and have previously been hospitalized for ARF. The study is being conducted in Baltimore, Maryland.
