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.
|Condition or disease||Intervention/treatment||Phase|
|Cystic Fibrosis||Drug: pioglitazone||Not Applicable|
- 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
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||21 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Masking Description:||This was open-label and no one was masked.|
