Multiple strengths of mometasone furoate/formoterol (MF/F) MDI combination therapy are under investigation as new treatments for asthma. We report efficacy/safety findings from a 3-month MF/F study in subjects with severe asthma.
This was a 3-month, randomized, double-blind, parallel-group, multicenter study with a 2-3-week open-label, run-in period of mometasone furoate (MF) 400 μg twice-daily (BID). Subjects (≥12 years) were randomized to MF/F (200/10 μg or 400/10 μg BID) or MF (400 μg BID). The primary endpoint was the area under the curve (AUC) of the change in serial FEV1 (0-12 hours) for MF/F 400/10 μg vs MF 400 μg from baseline to Week 12. Adverse events (AEs) and other clinical safety measures were recorded.
A total of 728 subjects (mean: age = 47.9 y, asthma duration = 14.0 y, FEV1 % predicted = 66.3, reversibility = 22.9%, Asthma Control Questionnaire [ACQ] score = 1.93) were randomized. Improvements in mean changes from baseline in FEV1 AUC0-12 h (L × h) at Week 12 were MF/F 200/10 μg = 3.59, MF/F 400/10 μg = 4.19, and MF 400 μg = 2.04, with both MF/F doses significantly better than MF (p < 0.001). These FEV1s correspond to average hourly increases of 0.30, 0.35, and 0.17 L, respectively. MF/F was associated with rapid (< 5 min) and sustained improvement in lung function. The percentage of subjects experiencing asthma deterioration (ie, severe asthma exacerbation) was 12.4% (MF/F 200/10 μg), 12.2% (MF/F 400/10 μg), and 18.3% (MF 400 μg). There were no notable differences in AEs between the groups.
Both medium- and high-dose MF/F combination therapy led to significantly greater improvements in lung function compared with high-dose MF monotherapy in severe asthmatics.
