| NCT00636961 | An Exploratory Study, to Assess the Effect of Repeat-dose Inhaled Indacaterol Maleate (300 μg) on Dynamic and Static Lung Hyperinflation, Subjective Breathlessness and Health Status in Patients With Chronic Obstructive Pulmonary Disease(COPD) | PHASE2 | COMPLETED | 27 | — | — | Feb 1, 2008 | Aug 1, 2008 | Aug 30, 2011 | 3 | Germany |
At the end of each 3 week treatment period, patients completed constant-load cycle ergometry testing at a work-rate of 75% of the Wmax determined at Screening. This work-rate was maintained until symptom limitation caused the patient to stop exercising. The time from the start of loaded pedaling until the patient stopped exercising was recorded.
FEV1 was measured with spirometry conducted according to internationally accepted standards. Trough FEV1 was defined as the average of measurements made 23 hours 10 minutes and 23 hours 45 minutes post-dose at the end of each treatment period. The analysis included baseline FEV1, defined as the average of the FEV1 values measured at 50 and 15 minutes prior to the first study drug administration in that period, as a covariate.
Inspiratory capacity (IC) at peak time and at isotime were the primary pharmacodynamic (PD) variables of interest. IC was measured at two minute intervals during exercise. Isotime was defined as the time the subject was still exercising in the shortest of all sub-maximal exercise tests (3-minutes resting pedaling, 3-minutes unloaded pedaling and exercise with loaded pedaling). Peak time was defined as the last measurement taken in the exercise period. The primary analysis consisted of a linear mixed effects model with baseline IC measurement as covariate.

| Indacaterol 300 μg followed by placebo | EXPERIMENTAL | Patients first received indacaterol 300 μg delivered via a single dose dry powder inhaler (SDDPI) once daily (od) in the morning for 3 weeks. After a 3-week washout period, patients received placebo delivered od via a SDDPI in the morning for 3 weeks. 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. |
