Abstract
RATIONALE: The purpose of this study was to investigate the clinical efficacy and safety of a fixed-dose combination of mometasone furoate/formoterol fumarate (MF/F) administered via a metered-dose inhaler in subjects with moderate-to-very severe chronic obstructive pulmonary disease (COPD).
METHODS: This multicenter, double-blind, placebo-controlled trial had a 26-week treatment period and a 26-week safety extension. Subjects (n = 1196), at least 40 years old, were current or ex-smokers randomized to twice-daily inhaled MF/F 400/10 μg, MF/F 200/10 μg, MF 400 μg, F 10 μg, or placebo. The trial's co-primary endpoints were mean changes from baseline, as area under the curve (AUC), in forced expiratory volume (FEV1) over 0-12 hours (AUC0-12 h FEV1) with MF/F versus MF, and in morning (AM) pre-dose (trough) FEV1 with MF/F versus F after 13 weeks of treatment. Key secondary endpoints were the effects of MF/F on respiratory health status using the Saint George's Respiratory Questionnaire (SGRQ), symptom-free nights, partly stable COPD at 26 weeks, and time to first COPD exacerbation.
RESULTS: The largest improvements in AUC0-12 h FEV1 were observed with MF/F 400/10 μg and MF/F 200/10 μg. Serial spirometry results demonstrated that bronchodilator effects with MF/F occurred rapidly (within 5 minutes), persisted for 12 hours after dosing, and were sustained over the 26-week treatment period. Similar findings were observed for AM pre-dose FEV1, for which effects were further investigated, excluding subjects whose AM FEV1 data were incorrectly collected after 2 days from the last dose of study treatment. Improvements in SGRQ scores surpassed the minimum clinically important difference of more than four units with both MF/F treatments. At 26 weeks, no notable between-treatment differences in the occurrence and nature of adverse events (AEs) were reported. No unexpected AEs were observed. Overall, 90 subjects reported AEs considered to be treatment-related, the most common of which were lenticular opacities, dysphonia, and oral candidiasis.
DISCUSSION: In conclusion, MF/F treatments improved lung function and respiratory health status, reduced exacerbations, and were well tolerated in subjects with moderate-to-very severe COPD.
