Pulmonary Ambulatory Clinical Trials


The Pulmonary Ambulatory Clinical Trials group is dedicated to conducting outpatient Phase 2 and Phase 3 drug studies in a range of pulmonary diseases. Based in the Division of Pulmonary, Allergy, and Critical Care Medicine, we have been carrying out industry and investigator-initiated studies since 2012. Our mission is to produce high-quality data, in partnership with our research participants, for evaluation of promising new treatments.
