Comparison of twice-daily inhaled ciclesonide and fluticasone propionate in patients with moderate-to-severe persistent asthma.

Objective: To investigate the relative efficacy of ciclesonide and fluticasone propionate (FP) administered at comparable microgram doses in maintaining asthma control in patients with moderate-to-severe persistent asthma.

Methods: This randomized, open-label, parallel-group study enrolled patients aged 12-75 years with a 6-month history of bronchial asthma. To enter a 2-week run-in period, patients had to have received FP 500-1000 microg/day or equivalent at a stable dose for 4 weeks and have a forced expiratory volume in 1s (FEV 1) 80% of predicted.
