  • All patients must have been on maintenance treatment with an inhaled corticosteroid at a stable medium dose, either as mono treatment or in combination with another controller medication, for at least 4 weeks before Visit 1. While the LTRA is permitted throughout the trial, the LABA has to be stopped at least 24 hours prior to Visit 1, as no LABAs are permitted during screening and treatment period of this trial.
  • All patients must be symptomatic (partly controlled) at Visit 1 and prior to randomisation at Visit 2 as defined by an Asthma Control Questionnaire (ACQ-IA) mean score >= 1.5.
  • All patients must have a pre-bronchodilator forced expiratory volume in one second (FEV1) >= 60% and =< 90% of predicted normal at Visit 1.
  • Variation of absolute FEV1 values of Visit 1 (pre-bronchodilator, considered as 100%) as compared to Visit 2 (pre-dose) must be within ± 30%.
  • All patients must confirm the diagnosis of asthma by bronchodilator reversibility at Visit 1, resulting in an increase in FEV1 of >= 12%, 15 to 30 minutes after 200 mcg salbutamol/albuterol.
  • Patients must be able to use the Respimat inhaler correctly.
  • Patients must be able to perform all trial related procedures including technically acceptable pulmonary function tests and use of electronic diary/peak flow meter (diary compliance of at least 80% is required).
