Trial Outcomes & Findings for Study of Indacaterol Dosed in the Evening in Patients With Chronic Obstructive Pulmonary Disease (COPD) (NCT NCT00615030)

NCT ID: NCT00615030

Last Updated: 2011-08-17

Results Overview

Trough FEV1 was assessed by performing spirometry measurements in the clinic for each treatment period. For the primary efficacy variable, trough FEV1 is the mean of two measurements taken at 23h 10 min and 23h 45 min post dose. The primary variable was analyzed using an analysis of covariance (ANCOVA) model with the (period) baseline FEV1 as covariate. The (period) baseline FEV1 was defined as the value measured before the study drug administration in that treatment period.

Participant Flow

Patients were randomized to one of the 12 possible treatment sequences of the double-blind 10-week treatment phase (Week 1 - 10). Each treatment sequence was divided into three treatment periods (I/II/III) of 15-day duration each. The first and second treatment period of each sequence was followed by a 2-week washout period.

Total 96 patients were randomized; one randomized patient discontinued from the study prior to exposure to study drug because of abnormal test procedure(s) result.

PRIMARY outcome

Timeframe: After 14 days of treatment

Population: The modified intention-to-treat (mITT) population included all randomized patients who received at least one dose of study drug. Patients who received only one treatment were also included for calculation of treatment means. This analysis included all patients who received indacaterol in the evening or placebo in their assigned treatment sequence.

Trough FEV1 was assessed by performing spirometry measurements in the clinic for each treatment period. For the primary efficacy variable, trough FEV1 is the mean of two measurements taken at 23h 10 min and 23h 45 min post dose. The primary variable was analyzed using an analysis of covariance (ANCOVA) model with the (period) baseline FEV1 as covariate. The (period) baseline FEV1 was defined as the value measured before the study drug administration in that treatment period.
