Study Summary

This trial aims to provide prospective evidence of the safety and efficacy of mannitol 400 mg b.i.d. in subjects aged 18 years and above. We hypothesize that inhaled mannitol 400 mg b.i.d. will increase the mean change from baseline FEV1 (mL) compared to control over the 26-week treatment period in adult subjects with cystic fibrosis. Any improvement in FEV1 is considered clinically meaningful, however, this trial has set a threshold of 80 mL for the purposes of determining an appropriate sample size for statistical power while retaining trial feasibility in an orphan disease population

Primary Outcome

The mean absolute change from baseline FEV1 (mL) over 26 weeks (measured at week 6, 14 and 26) will be compared between the two treatment groups with a REML (restricted maximum likelihood) based repeated measures approach. Least square means presented are for the average change over the 6, 14, and 26 week visits. Missing values due to withdrawal for reasons related to safety or efficacy were imputed using a baseline observation carried forward approach (BOCF).

Interventions

  • DRUG Inhaled mannitol
  • DRUG Placebo Comparator: Arm B - Control
