- Patients older than 18 years of age will be invited to join the Bronchiectasis Research Registry, a program supported by the Chronic Obstructive Pulmonary Disease (COPD) Foundation. The purpose of the program is to identify a group of people who are interested in receiving information about research studies focused on bronchiectasis and possibly participating in these research studies. Participants may be offered the opportunity to participate in selected clinic trials related to bronchiectasis or related medical conditions.
