A study to investigate the effects of different dose levels of abediterol administered once daily during four weeks to patients with symptomatic asthma on inhaled corticosteroids compared to patients given an open label comparator or placebo. The study will evaluate the efficacy of abediterol, how this study drug is absorbed in the blood stream and how safe and tolerable it is for the patients.

A randomised, double-blind, placebo- and active-controlled, parallel-arm, multicentre study to assess efficacy, pharmacokinetics, safety and tolerability of multiple dose levels of abediterol administered once daily for four weeks, in patients with asthma symptomatic on inhaled corticosteroids
