Abediterol (all doses) significantly increased change from baseline in trough FEV1 vs placebo on Day 7 (p<0.05; Table). Change from baseline in peak FEV1 was also significant for abediterol (all doses) vs placebo on Day 1 (all p<0.001) and Day 7 (all p<0.01).Peak FEV1 was 2-4 hours post-dose.Adverse events (AE) incidence was similar across groups; 40-57% of patients reported >=1 treatment-emergent AE with abediterol vs 47% with placebo (91% were mild-to-moderate in intensity).Conclusion:Once-daily abediterol 2.5-10 μg provided clinically relevant and statistically significant improvements from baseline in trough and peak FEV1 vs placebo from first dose, with no dose-response in bronchodilation.Abediterol was safe and well tolerated.View this table:Table.
