This study examines the effectiveness of JBT-101 as a therapy for inflammation in Cystic Fibrosis. JBT-101 is an investigational drug that has been designed to ?resolve? or ?turn-off? active immune responses and inflammation and to stop tissue scarring from getting worse, returning the body to a more normal state. The chemical structure of JBT-101 is similar to the breakdown product of a chemical in marijuana called cannaboids. JBT-101 has been designed to avoid the ?high feeling? of marijuana.
