• Patients with a post-bronchodilator forced expiratory volume in 1 second (FEV1) ≥30% and < 80% of the predicted normal, and post-bronchodilator FEV1/forced vital capacity (FVC) < 0.7 at Visit 2. For non-Japanese patients predicted FEV1 should be calculated according to Quanjer predictive equations [Quanjer PH 1993], for Japanese patients predicted FEV1 should be calculated according to Japanese Respiratory Society predictive tables [Japan Respiratory Society 2001].

Exclusion criteria

• Pregnant women or nursing mothers (pregnancy confirmed by positive urine pregnancy test).

Patients who develop a respiratory tract infection during the screening period (up to Visit 3) must discontinue from the trial, but will be permitted to re-enroll at a later date (at least 6 weeks after the resolution of the respiratory tract infection).
• Patients who, in the judgment of the investigator or the responsible Novartis personnel, have a clinically relevant laboratory abnormality or a clinically significant condition such as (but not limited to) unstable ischemic heart disease, cancers, left ventricular failure, long term prednisone therapy, history of myocardial infarction, arrhythmia (all), narrow angle glaucoma, symptomatic prostatic hyperplasia or bladder-neck obstruction or moderate to severe renal impairment.
