Safety and Efficacy of Pioglitazone as an Anti-inflammatory for the Treatment of Cystic Fibrosis (CF) Lung Disease
A Pilot Study Assessing the Safety and Efficacy of Pioglitazone as an Anti-inflammatory Agent for the Treatment of CF Lung Disease in Patients With Cystic Fibrosis
Study Hypothesis: Pioglitazone may decrease inflammation in cystic fibrosis lung disease.
Primary outcomes: Markers of inflammation (neutrophils, elastase, cytokines and bacteria)will be measured in induced sputum specimens before and after a 4 week treatment period with pioglitazone in clinically stable CF patients.

Detaljeret beskrivelse
- Single-center, open label study of pioglitazone in clinically stable patients with mild to moderate CF lung disease
- Induced sputum will be obtained from each subject at enrollment (Baseline) and again following 28 days of pioglitazone treatment (End of Treatment)
- Changes in markers of inflammation in the sputum samples will be assessed
- Safety measures, including complete blood count (CBC), serum chemistry, Erythrocyte sedimentation rate (ESR), C-Reactive Protein (CRP), urinalysis and spirometry, will also be assessed
