Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Indacaterol 150 μg

Indacaterol 150 μg once daily in the morning, inhaled via a single dose dry powder inhaler (SDDPI). Placebo to Salmeterol delivered twice daily via a proprietary dry powder inhaler in the morning and in the evening.

Daily inhaled corticosteroid treatment (if applicable) was allowed to remain stable throughout the study. The short acting (beta) β2-agonist (SABA) salbutamol/albuterol was available for rescue use throughout the study.

 Drug: Indacaterol 150 μg
Indacaterol 150 μg once daily (o.d) inhaled

Drug: Placebo to Salmeterol
Placebo to salmeterol delivered via a proprietary dry powder inhaler
Placebo Comparator: Placebo

Placebo to Indacaterol once daily in the morning, inhaled via a single dose dry powder inhaler (SDDPI). Placebo to Salmeterol delivered twice daily via a proprietary dry powder inhaler in the morning and in the evening.

Daily inhaled corticosteroid treatment (if applicable) was allowed to remain stable throughout the study. The short acting (beta) β2-agonist (SABA) salbutamol/albuterol was available for rescue use throughout the study.

 Drug: Placebo to Indacaterol
Placebo to Indacaterol inhaled via SDDPI.

Drug: Placebo to Salmeterol
Placebo to salmeterol delivered via a proprietary dry powder inhaler
Active Comparator: Salmeterol 50 μg

Salmeterol 50 μg twice daily delivered via a proprietary dry powder inhaler in the morning and in the evening. Placebo to Indacaterol daily in the morning, inhaled via a single dose dry powder inhaler (SDDPI).

Daily inhaled corticosteroid treatment (if applicable) was allowed to remain stable throughout the study. The short acting (beta) β2-agonist (SABA) salbutamol/albuterol was available for rescue use throughout the study.

 Drug: Salmeterol 50 μg
Salmeterol 50 μg twice daily (b.i.d) delivered via a proprietary dry powder inhaler

Drug: Placebo to Indacaterol
Placebo to Indacaterol inhaled via SDDPI.


Outcome Measures

Primary Outcome Measures :
  1. Trough Forced Expiratory Volume in 1 Second (FEV1) After 12 Weeks of Treatment [ Time Frame: Week 12 ]
    Spirometry was conducted according to internationally accepted standards. Trough FEV1 was defined as the average of the 23 hour 10 minute and 23 hour 45 minute post-dose FEV1 readings. Mixed model used baseline FEV1, FEV1 prior to and 10-15 minutes post inhalation of salbutamol/albuterol, and FEV1 prior to and 1 hour post inhalation of ipratropium as covariates.


Secondary Outcome Measures :
  1. St. George's Respiratory Questionnaire (SGRQ) Total Score After 12 Weeks of Treatment [ Time Frame: Week 12 ]
    SGRQ is a health related quality of life questionnaire consisting of 76 items in three sections: symptoms, activity and impacts. The total score is 0 to 100 with a higher score indicating poorer health status. The mixed model used baseline SGRQ total score, FEV1 prior to and 30 minutes post inhalation of salbutamol/albuterol, and FEV1 prior to and one hour post inhalation of ipratropium as covariates.

  2. Percentage of COPD "Days of Poor Control" During 26 Weeks of Treatment [ Time Frame: Up to 26 weeks ]
    Participants rated their symptoms on a scale of 0=none to 3=severe. A Chronic Obstructive Pulmonary Disease (COPD) "day of poor control" was defined as any day in the participants diary with a score >=2 (moderate or severe) for at least 2 of 5 symptoms (cough, wheeze, production of sputum, color of sputum, breathlessness). The mixed model used baseline percentage of "days of poor control", FEV1 prior to and 30 minutes post inhalation of salbutamol/albuterol, and FEV1 prior to and one hour post inhalation of ipratropium as covariates.
