Participant Flow

All patients who will be approached for participation in this trial will first be identified using either Port CF (CFF Registry) or CF Center database. Once potentials are identified a chart review will be conducted to determine eligibility. Patients will approached at clinic for possible participation in the study.

Washout: A 4 week washout from chronic use of NSAIDs, corticosteroids and oral meds to treat diabetes will be required. Subjects will be excluded if they take these medication within 72 hours of Visit 1. Subjects using alternate month tobramycin for inhalation (TOBI) will need to be on an off cycle to participate in this study.

PRIMARY outcome

Timeframe: Day 0 and Day 29

Population: Of the 20 enrolled subjects, one did not produce sputum at Baseline and a second subject's Post-Treatment sputum sample was lost due to a lab error. This reduced the number of subjects per group to 19. Of these 19 subjects, 18 subjects had both Baseline and Post-Treatment sputum samples.
