Study Arms:
- Indacaterol - placebo - tiotropium (Type: EXPERIMENTAL): In treatment period 1, patients received indacaterol 150µg once daily; in treatment period 2, patients received placebo to indacaterol once daily; in treatment period 3, patients received tiotropium 18µg once daily. Patients received indacaterol and placebo by single-dose dry powder inhaler (SDDPI); tiotropium was delivered via a proprietary inhalation device. There was a washout period of 13 days between each period. Use of fixed-dose combination of an anticholinergic plus a short-acting β2-agonist and use of long-acting β2-agonists were discontinued. Salbutamol rescue use was allowed during the treatment period as needed.
- Placebo - Tiotropium - Indacaterol (Type: EXPERIMENTAL): In treatment period 1, patients received placebo to indacaterol once daily; in treatment period 2, patients received tiotropium 18µg once daily; in treatment period 3, patients received indacaterol 150µg once daily. Patients received indacaterol and placebo by single-dose dry powder inhaler (SDDPI); tiotropium was delivered via a proprietary inhalation device. There was a washout period of 13 days between each period. Use of fixed-dose combination of an anticholinergic plus a short-acting β2-agonist and use of long-acting β2-agonists were discontinued.
