Clinical Trials

Has your doctor recommended right heart cardiac catheterization for you? This study is investigating new magnetic resonance imaging (MRI) techniques that use a guidewire to help position a heart catheter within the heart. MRI fluoroscopy shows pictures of the heart so that doctors can watch while they work. Using the guidewire during MRI may improve the procedure of heart catheterization. To participate in this study, you must be at least 18 years old, and your doctor must have recommended right heart catheterization for you. This study is located in Bethesda, Maryland.

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.

Are you an adult with sickle cell disease or would like to help research? Some people who have sickle cell disease are at greater risk for developing abnormal blood clots (venous thromboembolism). This could be a blood clot in the leg (called deep vein thrombosis) or a clot that can break off and travel to the lung (called a pulmonary embolism). This study will look at the blood of people who have sickle cell disease and venous thromboembolism, as well as healthy volunteers, to help researchers develop better treatments to prevent blood clots. Participants in this study must be between 18 and 80 years old and be either a healthy volunteer or have sickle cell disease or trait. This study is located in Bethesda, Maryland.

Are you an adult willing to give blood samples? This study investigates ways to prevent blood clotting in people with sickle cell disease. In this population, blood clotting is the most common cause of vascular death after heart attack and stroke. Scientists are studying the blood of people with sickle cell disease and comparing it with the blood of people without sickle cell disease over 2 years. To participate in this study, you must be between the ages of 18 and 80 years old and willing to participate for up to 2 years. This study takes place in Bethesda, Maryland.

This study is testing whether a new imaging technique can help healthcare providers diagnose venous thromboembolism. To participate in this study, you must be at least 18 years old and diagnosed with venous thromboembolism. This study takes place in Boston, Massachusetts.
