Trial Outcomes & Findings for Efficacy, Safety and Pharmacokinetics of Different Regimens of Indacaterol (NCT NCT01156844)

NCT ID: NCT01156844

Last Updated: 2011-08-17

Results Overview

Spirometry was conducted according to internationally accepted standards. Trough FEV1 values were calculated as the mean of the 23.17 hours and 23.75 hours post morning dose FEV1 measurements. Analysis of covariance model was used with baseline FEV1 as a continuous covariate.

• Recruitment status: COMPLETED
• Study phase: PHASE2

Participant Flow

The study consisted of a 21 day screening period, a 14 day run-in period and a baseline assessment day prior to the 16 day treatment period. 1 participant randomized to 75 ug Indacaterol and 1 participant randomized to Placebo did not receive study drug and were not included in the Safety set milestone.

Timeframe: Baseline, 0-24 hours post dose week 2

Population: Pharmacodynamic (PD) Analysis Set included all randomized participants who received at least one dose of study drug and who had evaluable PD data.

Spirometry was conducted according to internationally accepted standards. Standardized area under the curve (AUC 0-24 hours) of FEV1 measurements taken at pre-dose to 24 hours post-dose was calculated based on the trapezoidal rule and was adjusted for the area per time unit using the scheduled time of measurements for FEV1.
