OBJECTIVE: The reduction of oral prednisone use by mometasone furoate (MF) delivered by HFA-227 metered dose inhaler (MDI) was examined in oral corticosteroid (OCS)-dependent patients with severe persistent asthma. METHODS: A 3-month, double-blind, placebo-controlled clinical trial (n=123), followed by a 9-month open-label phase (n=120). The study was conducted at 26 medical centers in the United States. Patients were randomized to treatment with MF-MDI 400 or 800mug twice-daily (bid) doses, or placebo in the double-blind trial. All patients received MF in the open-label phase. RESULTS: At the endpoint of the double-blind trial, MF-MDI 400 and 800mug bid reduced the daily OCS dose by 39.4% and 31.1%, respectively, while placebo increased the OCS dose by 107.2% (P<0.01). The OCS requirement was reduced by 50% or more in 63% and 60% of patients treated with MF-MDI 400 and 800mug bid, respectively, compared with 14% of patients receiving placebo. After 12 weeks, despite prednisone reductions, pulmonary function, asthma symptoms, albuterol use, nocturnal awakenings, and physician-evaluated response to therapy also showed significant improvement with MF-MDI treatment compared with placebo. Further reductions in OCS requirements were achieved with long-term MF-MDI treatment in the open-label phase, with an overall 67% reduction in prednisone usage and 51% of patients completely eliminating prednisone usage by the 1-year time point. CONCLUSION: MF delivered by HFA-227 MDI significantly reduces daily OCS use compared with placebo and facilitates elimination of OCS use in patients with severe persistent asthma.
