What researchers measure

Primary outcomes

  1. Annualized Rate of Moderate or Severe Chronic Obstructive Pulmonary Disease (COPD) Exacerbations Over the 52-week Treatment Period

    Moderate exacerbations were recorded by the Investigator and defined as acute exacerbation of COPD (AECOPD) event that required either systemic corticosteroids (such as intramuscular, intravenous, or oral) and/or antibiotics. Severe exacerbations were also recorded by the Investigator and defined as AECOPD event that required hospitalization or observation for \>24 hours in an emergency department/urgent care facility or resulted in death. For both moderate and severe events to be counted as separate events, they were separated by at least 14 days. Annualized event rate was the total number of events that occurred during the 52-week treatment period divided by the total number of participant-years followed in the 52-week treatment period.

    Time frame: Baseline (Day 1) to Week 52

Secondary outcomes

  1. Change From Baseline in Pre-Bronchodilator Forced Expiratory Volume in 1 Second (FEV1) to Week 12

    The FEV1 was defined as the volume of air exhaled from the lungs in the first second of a forced expiration as measured by spirometer. Spirometry was performed after a wash out period of bronchodilators according to their action duration. Baseline was defined as the last available value up to randomization but prior to the first dose of study treatment.

    Time frame: Baseline (Day 1) and Week 12

  2. Change From Baseline in Saint George's Respiratory Questionnaire (SGRQ) Total Score to Week 52

    The SGRQ is a 50-item self-administered questionnaire designed to measure and quantify health status in adult participants with chronic airflow limitation and rated on electronic diary. Scores by dimension were calculated for 3 domains: symptoms (respiratory symptoms: frequency and severity), activity (activities that cause or are limited by breathlessness) and impacts (social functioning and psychological disturbances due to airway disease). Each question's response had a unique empirically derived weight where lowest possible weight was 0 and the highest was 100. Total score was obtained by summing all positive responses in the questionnaire. The total score and domain score was derived from the relevant items and converted to a score of 0 to 100 with a higher score indicating worse health status/health related quality of life. Baseline was defined as the last available value up to randomization but prior to the first dose of study treatment.

    Time frame: Baseline (Day 1) and Week 52

  3. Percentage of Participants With Saint George's Respiratory Questionnaire Improvement ≥4 Points at Week 52

FEF 25-75% was defined as the FEF at 25% to 75% of forced vital capacity (FVC), where FVC was defined as the volume of air that can be forcibly blown out after full inspiration in the upright position. Spirometry was performed after a wash out period of bronchodilators according to their action duration. Baseline was defined as the last available value up to randomization but prior to the first dose of study treatment.

SecondaryTime to First Moderate or Severe Chronic Obstructive Pulmonary Disease Exacerbation Event During the 52-week Treatment Period

The time to first moderate or severe exacerbation was defined as date of the first event minus randomization date +1. Moderate exacerbations were recorded by the Investigator and defined as AECOPD event that required either systemic corticosteroids (such as intramuscular, intravenous, or oral) and/or antibiotics. Severe exacerbations were recorded by the Investigator and defined as AECOPD event that required hospitalization or observation for \>24 hours in an emergency department/urgent care facility or resulted in death. For both moderate and severe events to be counted as separate events, they were separated by at least 14 days. Median time as well as 95% confidence interval was calculated using Kaplan-Meier estimates.
