Inhaled corticosteroids are recognized as first-line therapy in the management of asthma; however, their use may be limited by systemic and local side-effects. Ciclesonide, a novel pro-drug inhaled corticosteroid, is activated in the lungs and is expected to have less systemic and local side-effects. This study evaluated the efficacy and safety of ciclesonide in hydrofluoroalkane (HFA) compared with beclomethasone dipropionate (BDP) in a chlorofluorocarbon (CFC) formulation in adult patients with moderate to severe asthma.


This was a multicentre, randomized, open-label, parallel-group comparative study. The patients were given 800 microg/day of CFC-BDP in the four-week baseline period. After the baseline period, 319 patients were randomly allocated into three groups which, respectively, received HFA-ciclesonide 400 microg/day (without a spacer), HFA-ciclesonide 800 microg/day (without spacer) and CFC-BDP 800 microg/day (with spacer) for the eight-week treatment period. The primary efficacy variable was morning PEF.


The morning PEF increased by 16.02 L/min in the 400 microg HFA-ciclesonide group, 23.98 L/min in the 800 microg HFA-ciclesonide group and 5.91 L/min in the 800 microg CFC-BDP group. Better outcomes were achieved by the use of 800 microg/day of HFA-ciclesonide compared with 800 microg/day of CFC-BDP (P = 0.001). There was no difference in adverse events between the groups.


In adult patients with moderate to severe asthma, 800 microg/day of HFA-ciclesonide was significantly more effective than 800 microg/day of CFC-BDP. Ciclesonide at doses of 400 microg/day and 800 microg/day was safe and well tolerated.
