- Smoking history of at least 20 pack years
- Post-bronchodilator forced expiratory volume in 1 second (FEV1) < 80% and ≥ 30% of the predicted normal value
Post-bronchodilator FEV1/FVC (forced volume capacity) < 70% (Post refers to within 30 minutes after inhalation of 400 μg of salbutamol)

Active Comparator

Indacaterol 300 μg plus placebo to formoterol
Indacaterol 600 μg plus placebo to formoterol
Formoterol 12 μg plus placebo to indacaterol
Placebo to indacaterol plus placebo to formoterol
Patients inhaled indacaterol 300 μg once daily via a single-dose dry-powder inhaler (SDDPI), placebo to indacaterol once daily via a SDDPI, and placebo to formoterol twice daily via the manufacturer's proprietary inhalation device (Aerolizer®). Indacaterol, placebo to indacaterol, and placebo to formoterol were taken in the morning between 8:00 and 10:00 AM; placebo to formoterol was taken again 12 hours later in the evening between 8:00 and 10:00 PM. Daily inhaled corticosteroid treatment (if applicable) was to remain stable throughout the study. The short-acting β2-agonist salbutamol/albuterol was available for rescue use throughout the study.
Patients inhaled indacaterol 600 μg (two 300 μg capsules) once daily via single-dose dry-powder inhalers (SDDPI) plus placebo to formoterol twice daily via the manufacturer's proprietary inhalation device (Aerolizer®).
