Study Arms:
- Sequence 1: Placebo,Tiotropium, Indacaterol 150 μg (Type: EXPERIMENTAL): In period I, placebo to indacaterol (150 or 300 μg) delivered via SDDPI. The placebo for blinding tiotropium was delivered via the tiotropium inhalation device. In period II, tiotropium (18 μg) once daily delivered via inhalation device and matching placebo to indacaterol delivered once daily via single dose dry powder inhaler (SDDPI). In period III, indacaterol 150 μg once daily delivered via SDDPI and placebo to tiotropium was delivered once daily via the tiotropium inhalation device. Daily inhaled corticosteroid (ICS) monotherapy (where applicable) was provided to remain stable throughout study. The Short acting (beta) β2-agonist (SABA) was available for rescue use throughout the study.
- Sequence 2: Indacaterol 300 μg, Indacaterol 150 μg, Tiotropium (Type: EXPERIMENTAL): In period I,indacaterol 300 μg once daily delivered via single dose dry powder inhaler (SDDPI)and matching placebo to tiotropium delivered once daily via tiotropium inhalation device. In period II, indacaterol 150 μg once daily delivered via SDDPI and matching placebo to tiotropium delivered once daily via tiotropium inhalation device. In period III, tiotropium (18 μg) once daily delivered via inhalation device and matching placebo to indacaterol delivered once daily via SDDPI. Daily ICS monotherapy (where applicable) was provided to remain stable throughout study. The SABA was available for rescue use throughout the study.
- Sequence 3: Indacaterol 150 μg, Indacaterol 300 μg, Placebo (Type: EXPERIMENTAL): In period I, indacaterol 150 μg once daily delivered via SDDPI and matching placebo to tiotropium delivered once daily via tiotropium inhalation device. In period II, indacaterol 300 μg once daily delivered via SDDPI and matching placebo to tiotropium delivered once daily via tiotropium inhalation device. In period III, placebo to indacaterol (150 or 300 μg) delivered via SDDPI. The placebo for blinding tiotropium was delivered via the tiotropium inhalation device. Daily ICS monotherapy (where applicable) was provided to remain stable throughout study. The SABA was available for rescue use throughout the study.
- Sequence 4: Tiotropium, Placebo, Indacaterol 300 μg (Type: EXPERIMENTAL): In period I, tiotropium (18 μg) once daily delivered via inhalation device and matching placebo to indacaterol delivered once daily via SDDPI. In period II, placebo to indacaterol (150 or 300 μg) delivered via SDDPI. The placebo for blinding tiotropium was delivered via the tiotropium inhalation device. In period III, indacaterol 300 μg once daily delivered via SDDPI and matching placebo to tiotropium delivered once daily via tiotropium inhalation device. Daily ICS monotherapy (where applicable) was provided to remain stable throughout study. The SABA was available for rescue use throughout the study.
