    Abstract:
    OBJECTIVE: To evaluate the efficacy and safety of three doses of ciclesonide (with or without spacer) in children with persistent asthma. PATIENTS AND METHODS: This was a multicentre, double-blind, placebo-controlled, 12-week study of ciclesonide 40, 80 or 160 μg (once daily pm). Children (6-11 years) were randomised 1:1 to treatment via a metered dose inhaler (MDI) or MDI plus spacer. The primary variable was change from baseline in mean morning peak expiratory flow (PEF). Secondary variables included: time to first lack of efficacy (LOE), asthma control, forced expiratory volume in 1 s (FEV(1)), asthma symptom score and quality of life (QoL). Safety assessments included: adverse events (AEs), urinary cortisol excretion and body height. RESULTS: In total, 1073 children received treatment. At endpoint, mean morning PEF significantly improved with all doses of ciclesonide vs. placebo. There was no difference over placebo in time to first LOE, but ciclesonide was superior to placebo on asthma control, symptom score, FEV(1) and QoL. There were no differences between the spacer or non-spacer subgroups. The incidences of AEs were comparable between treatment groups (approximately 35%) and there were no between-group differences in body height or urinary cortisol. CONCLUSIONS: Ciclesonide 40-160 μg once daily is effective and well tolerated in children with persistent asthma; its efficacy and safety are unaffected by the use of a spacer. clinicaltrials.gov registration number: NCT00384189.
