BACKGROUND: Once-daily dosing with an inhaled corticosteroid (ICS) may simplify asthma management and improve patient compliance. Since asthma is frequently worse at night, evening dosing appears to be a more obvious choice to accommodate the chronobiology of asthma than morning dosing. OBJECTIVE: The primary study objective was to compare the efficacy and safety of mometasone furoate (MF) dry powder inhaler (MF-DPI) 400 microg qd PM (one 400 microg inhalation) with placebo for the treatment of asthma in patients previously dependent on twice a day (bid, bis in die) ICS therapy. We also compared different regimens of MF-DPI with each other and with placebo. METHODS: This 12-week, multicenter, double-blind, placebo-controlled study evaluated lung function and asthma symptoms in 400 subjects with persistent asthma randomized to MF-DPI 200 microg qd (once a day, quaque die) PM, 400 microg qd PM as one inhalation from a 400 microg device, 400 microg qd PM as two inhalations from a 200 microg device, 200 microg twice daily (bid), or placebo. Evening doses were to be taken in the late afternoon or early evening, preferably before dinner time. RESULTS: Mean changes from baseline at endpoint in FEV1 (forced expiratory volume in 1 s) were similar for MF-DPI 400 microg qd PM (one inhalation; 0.41 L), MF-DPI 400 microg qd PM (2 inhalations; 0.49 L), MF-DPI 200 microg qd PM (0.41 L), and MF-DPI 200 microg bid (0.51 L); and all were significantly improved compared with placebo (0.16 L; p < 0.001). Secondary efficacy variables, including nocturnal awakenings and use of rescue albuterol, were also significantly improved with MF-DPI treatment compared with placebo. All treatments were generally safe and well tolerated, with adverse events of mild to moderate severity. CONCLUSIONS: Once-daily evening dosing of MF-DPI at doses of 400 and 200 microg restored lung function and improved nocturnal and daytime symptom control in subjects with asthma previously dependent on bid ICS therapy. Comparable effectiveness of a total daily dose of 400 microg was demonstrated between once daily in the evening and twice-daily administration. The results also confirm the effectiveness of MF-DPI 200 microg qd PM, the lowest dose studied.
