Effect of Pioglitazone on Inflammation in Cystic Fibrosis

Status Completed

Clinical Trial Summary

The purpose of this study is to determine the effect of pioglitazone on reducing airway inflammation in cystic fibrosis and characterize the amount and timecourse of pioglitazone elimination from the body.

Clinical Trial Description

Progressive loss of lung function due to chronic infection and inflammation is the primary cause of morbidity and mortality in patients with CF. Current therapies directed at treatment of chronic P. aeruginosa infection (e.g. aerosolized tobramycin, azithromycin) provide short-term improvement in pulmonary function; however, persistence of the infection/inflammation causes the inevitable loss of lung function. PPARgamma is a nuclear transcription factor which is known to reduce activation of NFKB, a central mediator of airway inflammation in CF. Recent studies demonstrate that PPARgamma expression is reduced in patients with CF and may offer a potential therapeutic target to combat airway inflammation in CF. Pioglitazone is a thiazolidinedione whose principal pharmacological target it PPARgamma. The purpose of this pilot study is to determine the pharmacokinetics/pharmacodynamics of pioglitazone and effect on reducing airway inflammation in cystic fibrosis. ;
