Input: Eighteen trials (reporting 20 study comparisons) met the review entry criteria. We report findings from 18 group comparisons where data were available (6343 participants, of whom 1692 were children). Ciclesonide versus placebo: The short duration of the included studies means that there is a lack of data with respect to the impact of ciclesonide on asthma exacerbations. At doses of 100 mcg/d or less up to 400 mcg/d in mild to moderate asthma, ciclesonide improved lung function, asthma symptoms and rescue inhaler use, compared with placebo. Dose response outcomes: Comparisons of 100 versus 200 mcg/d, 100 versus 400 mcg/d and 400 versus 800 mcg/d did not yield significant differences in lung function outcomes.  Adverse event data were not available in sufficient detail to permit assessment of the safety profile of this drug. Ciclesonide was more effective than placebo, in the short term, in improving lung function in patients with mild to moderate asthma previously treated with inhaled corticosteroids. There remain questions as to dose response, and the lack of data on the longer term impact on exacerbations and safety profile should be addressed in future studies.
Output:

The results from this review indicate that CIC at low to moderate doses improves lung function and reduces asthma symptoms compared to placebo, but the short duration of the studies means that there is a lack of information about the impact on asthma exacerbations. Thus the currently recommended doses of CIC of 100-200 mcg daily would seem appropriate. However, the number of studies in the higher dose range are low and further studies are therefore required in adults and children to determine whether higher CIC doses will give significant benefit without increasing adverse events. It will also be important to determine in clinical studies how CIC compares to the other currently available ICS in terms of efficacy and safety in asthmatic adults and children in order to determine the precise role of CIC therapy in asthma. The published data are insufficient to assess the reputed safety advantage of ciclesonide, and better assessment and reporting in studies is required to address this important question.
