Study design (if review, criteria of inclusion for studies)
Phase 3, randomized, double-blind, placebo-controlled, 24-week trial
Participants
A total of 352 patients greater than or equal to 5 years old with cystic fibrosis who had FEV(1) greater than or equal to 75% of predicted normal
Interventions
patients were randomized to receive inhaled denufosol, 60 mg, or placebo three times daily
Outcome measures
Mean change from baseline to Week 24 endpoint in FEV(1) (primary efficacy endpoint); secondary endpoints included exacerbation rate and other measures of lung function.
Main results
Mean change from baseline to Week 24 endpoint in FEV(1) (primary efficacy endpoint) was 0.048 L for denufosol (n = 178) and 0.003 L for placebo (n = 174; P = 0.047). No significant differences between groups were observed for secondary endpoints including exacerbation rate and other measures of lung function. Denufosol was well tolerated with adverse event and growth profiles similar to placebo.
Authors' conclusions
Denufosol improved lung function relative to placebo in cystic fibrosis patients with normal to mildly impaired lung function.
