Treatment and study plan

Indacaterol 150 μg

Drug

Indacaterol was supplied in powder filled capsules together with a single-dose dry-powder inhaler (SDDPI) device.

Tiotropium 18 μg

Drug

Tiotropium was supplied in powder filled capsules together with the manufacturer's proprietary inhalation device (HandiHaler®).

Placebo to Indacaterol

Primary outcomes

  1. Forced Expiratory Volume in 1 Second (FEV1) Standardized (With Respect to Length of Time) Area Under the Curve (AUC) From 5 Minutes to 8 Hours Post-dose at the End of the Study (Week 12, Day 84)

    Time frame: From 5 minutes to 8 hours post-dose at the end of the study (Week 12, Day 84)

    FEV1 was measured with spirometry conducted according to internationally accepted standards. Measurements were made at 5 and 30 minutes; and 1, 2, 3, 4, 6, and 8 hours post-dose at the end of the study (Week 12, Day 84). The standardized AUC FEV1 was calculated as the sum of trapezoids divided by the length of time. The analysis included baseline FEV1, FEV1 pre-dose and 10-15 minutes post-dose of salbutamol/albuterol during screening, and FEV1 pre-dose and 1 hour post-dose of ipratropium during screening as covariates.

Secondary outcomes

  1. Trough Forced Expiratory Volume in 1 Second (FEV1) 24 Hours Post-dose at the End of the Study (Week 12 + 1 Day, Day 85)

    Time frame: End of the study (Week 12 + 1 day, Day 85)

    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 the study. The analysis included baseline FEV1, FEV1 pre-dose and 10-15 minutes post-dose of salbutamol/albuterol during screening, and FEV1 pre-dose and 1 hour post-dose of ipratropium during screening as covariates.

  2. Forced Expiratory Volume in 1 Second (FEV1) Standardized (With Respect to Length of Time) Area Under the Curve (AUC) From 5 Minutes to 8 Hours Post-dose on Day 1

    Time frame: From 5 minutes to 8 hours post-dose on Day 1

    FEV1 was measured with spirometry conducted according to internationally accepted standards. Measurements were made at 5 and 30 minutes; and 1, 2, 3, 4, 6, and 8 hours post-dose on Day 1. The standardized AUC FEV1 was calculated as the sum of trapezoids divided by the length of time. The analysis included baseline FEV1, FEV1 pre-dose and 10-15 minutes post-dose of salbutamol/albuterol during screening, and FEV1 pre-dose and 1 hour post-dose of ipratropium during screening as covariates.

  3. Trough Forced Expiratory Volume in 1 Second (FEV1) 24 Hours Post-dose on Day 2

    Time frame: 24 hours post-dose on Day 2

    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 on Day 2. The analysis included baseline FEV1, FEV1 pre-dose and 10-15 minutes post-dose of salbutamol/albuterol during screening, and FEV1 pre-dose and 1 hour post-dose of ipratropium during screening as covariates.

  4. Forced Expiratory Volume in 1 Second (FEV1) Standardized (With Respect to Length of Time) Area Under the Curve (AUC) From 5 Minutes to 4 Hours Post-dose on Day 1

    Time frame: From 5 minutes to 4 hours post-dose on Day 1

    FEV1 was measured with spirometry conducted according to internationally accepted standards. Measurements were made at 5 and 30 minutes; and 1, 2, 3, and 4 hours post-dose on Day 1. The standardized AUC FEV1 was calculated as the sum of trapezoids divided by the length of time. The analysis included baseline FEV1, FEV1 pre-dose and 10-15 minutes post-dose of salbutamol/albuterol during screening, and FEV1 pre-dose and 1 hour post-dose of ipratropium during screening as covariates.

  5. Forced Expiratory Volume in 1 Second (FEV1) Standardized (With Respect to Length of Time) Area Under the Curve (AUC) From 5 Minutes to 4 Hours Post-dose at the End of the Study (Week 12, Day 84)

    Time frame: From 5 minutes to 4 hours post-dose at the end of the study (Week 12, Day 84)

    FEV1 was measured with spirometry conducted according to internationally accepted standards. Measurements were made at 5 and 30 minutes; and 1, 2, 3, and 4 hours post-dose at the end of the study (Week 12, Day 84). The standardized AUC FEV1 was calculated as the sum of trapezoids divided by the length of time. The analysis included baseline FEV1, FEV1 pre-dose and 10-15 minutes post-dose of salbutamol/albuterol during screening, and FEV1 pre-dose and 1 hour post-dose of ipratropium during screening as covariates.
