Title: Pilot Observational Study to Determine Feasibility of a Standardized Treatment of Pulmonary Exacerbations in Patients With Cystic Fibrosis
Brief Summary: The goal of this research study is to better understand current treatment practices for pulmonary exacerbations (lung infections) and whether the Cystic Fibrosis National Patient Registry (CFFNPR)can be used for this type of study.

* Ability to comply with study medication use, study visits and study procedures as judged by the investigator
* Ability to produce sputum or be willing to undergo an induction to produce sputum for clinical evaluation
* Clinically stable with no evidence of acute upper or lower respiratory tract infection of history of pulmonary exacerbation within 4 weeks prior to screening

Key Exclusion Criteria:

* Administration of any investigational drug within 8 weeks prior to Screening
* Emergency room visit or hospitalization for CF or respiratory-related illness within 4 weeks prior to screening

* Have received at least 3 courses of inhaled antimicrobials over the preceding 12 months
* Clinically stable with no changes in health status within the last 30 days
* Able to reproducibly produce sputum and perform spirometry

Exclusion Criteria (selected):

* Use of any nebulized or systemic antibiotics within 30 days prior to baseline
* History of hypersensitivity to fluoroquinolones or intolerance with aerosol medication
* Evidence of acute upper within 10 days or lower respiratory infections within 30 days prior to dosing
* Creatine clearance \< 50mg/ml, aspartate transaminase (AST), alanine transaminase (ALT) or total bilirubin \>/= 3 x upper limit of normal (ULN) at Screening
D: Inclusion Criteria:

* Documentation of CF diagnosis as evidenced by one or more clinical features consistent with the CF phenotype and one or more of the following criteria:
