Efficacy and Safety Characteristics of Mometasone Furoate/Formoterol Fumarate Fixed-Dose Combination in Subjects with Moderate to very Severe COPD: Findings from Pooled Analysis of Two Randomized, 52-Week Placebo-Controlled Trials
Background: A clinical trial 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) investigated the efficacy and safety of a fixed-dose combination of MF/F.
Methods: This multicenter, double-blind, placebo-controlled trial had a 26-week treatment period and a 26-week safety extension. Subjects (n = 1055; ≥40 years) were current or ex-smokers randomized to twice-daily treatment with inhaled MF/F 400/10 µg, MF/F 200/10 µg, MF 400 µg, F 10 µg, or placebo. The coprimary endpoints of the trial were mean changes from baseline in forced expiratory volume in 1 second (FEV1) over 0–12 hours (AUC0–12 FEV1) with MF/F versus MF, and in morning predose FEV1 with MF/F versus F. Key secondary endpoints were quality of life (Saint George’s Respiratory Questionnaire [SGRQ]), symptom-free nights, and partly stable COPD at 26 weeks, as well as time to first COPD exacerbation.
Results: Significant improvements in FEV1 AUC0–12 occurred at endpoint with MF/F 400/10 and MF/F 200/10 versus MF 400 (P ≤ 0.007). Significant bronchodilation occurred in 5 minutes with MF/F, and serial spirometry demonstrated sustained FEV1 improvements with MF/F over the treatment period. Significant improvements in morning predose FEV1 occurred with both MF/F doses, and these effects were further investigated by excluding results for subjects whose morning FEV1 data were collected >2 days after the last dose of study treatment. Improvements in SGRQ total scores surpassed the minimum clinically important difference of at least 4 units with MF/F 400/10. MF/F 400/10 significantly reduced the time-to-first COPD exacerbation. Similar proportions of subjects in all five treatment groups reported treatment-emergent adverse events. Rates of pneumonia were low (≤1.0%) across treatment groups.
Conclusion: MF/F 400/10 µg twice daily was shown to be an effective therapy for patients with moderate to very severe COPD, and both MF/F 400/10 µg twice daily and MF/F 200/10 µg twice daily were well tolerated.
