Clinical Trials

Alpha-1 Anti-trypsin Deficiency (AATD) is a genetic disease with lung and liver disease presentations. The purpose of this study is to examine the density of the lung as measured by chest computed tomography (CT) and determine if existing emphysema predicts changes in the rate of subsequent emphysema or changes in CT, serum or plasma biomarkers of interest. The overarching goal is to develop biomarkers that can be used in interventional trials since lung function changes do not typically inform disease progression in AATD.

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.

This is a multicenter, randomized, placebo-controlled, sequential dose-escalating, double-masked, safety study of sildenafil in premature infants with severe bronchopulmonary dysplasia,

The purpose of this study is to identify the optimal deimplementation strategies for an overused practice: continuous pulse oximetry monitoring of children hospitalized with bronchiolitis who are not receiving supplemental oxygen.

This study's objective is to identify and test pragmatic and sustainable strategies for implementing a multi-condition clinical pathway intervention for children hospitalized with asthma, pneumonia, or bronchiolitis in community hospitals.

This is a multicenter, randomized, placebo-controlled, sequential dose-escalating, double-masked, safety study of sildenafil in premature infants with severe bronchopulmonary dysplasia (BPD).

study is a feasibility pilot study to help us get information to design a larger trial of diuretic management for bronchopulmonary dysplasia.

Do you have chronic bronchitis and COPD and want to improve treatment? This study will be testing how well a medicine called ivacaftor that is used to treat cystic fibrosis works also to treat symptoms of chronic bronchitis. New research suggests chronic bronchitis may be due to a problem similar to cystic fibrosis. To participate in this study, you must be 40 to 80 years old, have a history of smoking, and have not been diagnosed with asthma or cystic fibrosis. This study will be conducted in Birmingham, Alabama.

Do you have COPD? This study will be looking for genes that may play a role in the development of COPD by looking at the blood from patients who have COPD, as well as the blood from those patients’ family members. To participate in this study, you must be 52 years old or younger and must not be pregnant or have other serious lung diseases such as lung cancer. This study will be conducted in Boston, Massachusetts.

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.
