        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.
