Clinical Trials and Studies

Are you a healthy adult? In this clinical trial, researchers are trying to improve the quality of heart CT scans by using new methods to create the images. Researchers will take normal CT images of the heart and compare those images to super high-resolution images made with a super-computer. Healthy adults aged 18 years or older may be able to participate. The study is taking place at the NIH Clinical Center in Bethesda, Maryland.

Are you at least 18 years old and scheduled for a CT of the chest, abdomen, and pelvis? In this study, researchers want to learn if new CT imaging methods with less radiation make images that are similar to traditional ways. If you are at least 18 and your doctor has said you need a CT scan of the chest, abdomen, or pelvis, you may be able to participate. This study is taking place at the National Institutes of Health Clinical Center in Bethesda, Maryland.

The goal of the study is to look at the relationship between how individuals with Sarcoidosis take the sarcoidosis medicines and how it affects the disease, to evaluate any factors that may make individuals not want to take the medicines, and to develop and refine ways to help support individuals with Sarcoidosis especially when it comes to the medicines. The overall hypothesis is higher medication adherence will be associated with better clinical outcomes in sarcoidosis. The investigators will enroll 150 patients with biopsy proven pulmonary sarcoidosis for at least one year who are on any oral treatment regimen for at least six months into a 12-month longitudinal study.

The purpose of this study is to determine if the SSRI fluoxetine (Prozac) can improve SNS responses during exercise.

The objective of the ALA-LHC is to establish a national cohort of young adults for the purpose of defining lung health and developing targets to intercept chronic lung disease at its earliest stages.

Do you have heart disease? This study is looking to improve the quality of heart CT scans by using new methods to create the images. You may be able to participate in the study if you are 18 years old or older, have heart disease, and have been told by your doctor that you need a CT scan. This study is taking place at the National Institutes of Health Clinical Center in Bethesda, Maryland.

Are you or your child at least 13 years old and have sickle cell disease? Do you or your child have sickle cell disease or beta-thalassemia? Researchers are testing whether a new antibody therapy prior to stem cell transplantation improves the success of the stem cell transplant in individuals at high risk for complications. Participants must be 13 years old or older. The study is taking place at the National Institutes of Health (NIH) Clinical Center in Bethesda, Maryland. Patients who have the stem cell transplant must live within 1 hour of the NIH Clinical Center for 3 months after the transplant.
The stem cells for the transplant come from a fully matched donor, 4 years old or older. Donors may provide blood samples for research.

Are you in need of a heart or lung transplant or have you had one in the past 3 months? Have you undergone a lung or heart transplant in the past 3 months or are you a candidate for heart or lung transplant? Some people with advanced heart and lung disease have heart and lung transplants but these new organs are often rejected. When this happens, patients must have repeated biopsies, which are invasive and expensive. Researchers in this clinical study want to see if a blood test can predict organ rejection and take the place of biopsies. To participate, you must be 18 to 80 years old and be a candidate for heart or lung transplant or have had a heart or lung transplant no more than three months ago. The study is taking place in Bethesda, Maryland, at the NIH Clinical Center, as well as in Baltimore, Maryland, and Falls Church, Virginia.

Are you a former smoker with COPD? Researchers are studying whether taking aspirin can help with COPD symptoms. Participants must be at least 40 years old, be diagnosed with COPD, and have a history of smoking at least 10 packs of cigarettes a year. The study is taking place in Baltimore, Maryland.

The goal of the study is to look at the relationship between how individuals with Sarcoidosis take the sarcoidosis medicines and how it affects the disease, to evaluate any factors that may make individuals not want to take the medicines, and to develop and refine ways to help support individuals with Sarcoidosis especially when it comes to the medicines.
