1.Primary Outcome
Title Rate of Moderate or Severe Exacerbations
Hide Description Moderate exacerbations are defined as clinically significant exacerbations that require treatment with oral/systemic corticosteroids and/or antibiotics. Severe exacerbations are defined as clinically significant exacerbations that require in-patient hospitalization (>=24 hours) or result in death. Moderate and severe exacerbations occurring from the start of investigational product (IP) up to the Week 52 visit, including exacerbations reported after early discontinuation from IP by participants who remained in the study, were included in the analysis. The analysis was performed on the modified intent-to-treat (mITT) Population (all randomized participants who received at least one dose of study treatment).

4.Secondary Outcome
Title Change From Baseline in Mean Total St. George's Respiratory Questionnaire (SGRQ) Score
Hide Description The SGRQ for COPD is a 40-item questionnaire derived from the original SGRQ , designed to measure health impairment by addressing the frequency of respiratory symptoms and current state of the participant. SGRQ Total Scores range from 0 to 100 with higher scores indicating worse health-related quality of life and reductions indicating improvement. The Baseline value will be the last measurement collected prior to the first dose of investigational product.Change from Baseline is calculated as the post-dose visit value minus the Baseline value. Mean change from Baseline in SGRQ score at Week 52 has been presented.

5.Secondary Outcome
Title Change From Baseline in Mean COPD Assessment Test (CAT) Score
Hide Description The CAT is an 8-item questionnaire developed for use in routine clinical practice to measure the health status of participants with COPD. Each question is assessed on a 6-point scale ranging from 0 (no impairment) to 5 (maximum impairment) with the CAT score ranging from 0-40. Higher scores indicate greater disease impact with reductions indicating improvement. The Baseline value will be the last measurement collected prior to the first dose of investigational product. Change from Baseline is calculated as the post-dose visit value minus the Baseline value. Mean change from Baseline in CAT score at Week 52 has been presented.
