OBJECTIVE: To investigate the efficacy and safety of ciclesonide in patients with severe asthma over a 1-year period. RESEARCH DESIGN AND METHODS: Patients aged 18 - 75 years with persistent asthma were enrolled in a 12-week, double-blind, randomized study and treated with ciclesonide 320 or 640 mug twice daily (b.i.d.) with the option of continuing in a 40-week extension phase (EP). MAIN OUTCOMES MEASURES: Change in morning peak expiratory flow (PEF) from baseline to 12 weeks and safety over 1 year. RESULTS: 365 patients were randomized and 275 continued into the EP. During 12 weeks' treatment, morning peak expiratory flow significantly increased by 16 l/min (p < 0.001) and 14 l/min (p = 0.001) in the 320 and 640 mug b.i.d. groups, respectively. Both doses significantly reduced total asthma symptom scores by 0.29 (p < 0.0001). In both groups, the incidence of adverse effects (AEs) was low and mean cortisol levels in serum and urine were not suppressed during the EP. CONCLUSIONS: Ciclesonide 320 mug b.i.d. sustained lung function and asthma symptoms in patients with severe asthma over 12 weeks' treatment, and maintained lung function during a 40-week EP; ciclesonide 640 mug b.i.d. did not provide additional benefits. Long-term use of ciclesonide was not associated with increased local AEs or negative effects on cortisol levels.
