Primary
| Measure | Time frame | Description |
|---|---|---|
| Annual COPD Exacerbation Rate Over 56 Weeks Treatment Comparison for Patients With Baseline EOS>=220/uL | Immediately following the first IP dose through week 56 | A COPD exacerbation is defined by symptomatic worsening of COPD requiring: * Use of systemic corticosteroids for at least 3 days; a single depot injectable dose of corticosteroids will be considered equivalent to a 3-day course of systemic corticosteroids; and/or * Use of antibiotics; and/or * An inpatient hospitalization or death due to COPD Annual COPD exacerbation rate is the number of exacerbations per year. Its raw rate is calculated by number of exacerbations divided by the treatment period and then normalized to an annual rate, and is estimated by negative binomial model. Rate ratio between two treatment groups is also estimated through this model. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Mean Change From Baseline to Week 56 in Pre-bronchodilator FEV1 (L) Value for Patients With Baseline EOS>=220/uL | First IP up to end of treatment Week 56 | Pre-bronchodilator FEV1 (L) is collected at Weeks 0, 4, 8, 16, 24, 32, 40, 48, and 56. Baseline is the last non-missing value with quality (acceptable or borderline quality grade) prior to the first dose of study treatment. |
| Mean Change From Baseline in SGRQ Total Score for Patients With Baseline EOS>=220/uL | First IP up to Week 56 | SGRQ is from 50-item PRO instrument. The SGRQ total score is expressed as a percentage of overall impairment, in which 100% means the worst possible health status and 0 indicates the best possible health status. |
| Mean Change From Baseline in CAT Total Score for Patients With Baseline EOS>=220/uL | First IP up to Week 56 | CAT is an 8-item PRO developed to measure the impact of COPD on health status. The instrument uses semantic differential six-point response scales. A CAT total score is the sum of item responses. Score ranges from 0 to 40 with higher scores indicative of greater COPD impact on health status. |
| Mean Change From Baseline in E-RS: COPD Total Score for Patients With Baseline EOS>=220/uL | First IP up to Week 56 | The E-RS: COPD is an 11-item PRO developed to evaluate the severity of respiratory symptoms of COPD. Summation of E-RS: COPD item responses produces a total score ranging from 0 to 40, with higher scores indicating greater severity. |
| Mean Change From Baseline in Total Rescue Medication Use (Number of Puffs Per Day) for Patients With Baseline EOS>=220/uL | First IP up to Week 56 | The number of rescue medication inhalations and nebulizer treatments taken are recorded by the patient in the eDiary twice daily. Total rescue medication use is the sum of daytime and night-time use. |
| Mean Change From Baseline in Proportion of Nights With Awakenings Due to Respiratory Symptoms for Patients With Baseline EOS>=220/uL | First IP up to Week 56 | Change from baseline to Week 56 in proportion of nights with awakenings due to respiratory symptoms. |

Respondents are instructed to complete the electronic diary (eDiary) each evening just prior to bedtime and to answer the questions while considering their experiences today. The daily EXACT-PRO total score is recorded and has a range of 0-100 with higher scores indicative of greater severity. COPD exacerbation event frequency is calculated based on comparison of the baseline score with daily total scores. An increase of EXACT-PRO total score ≥9 for 3 days or ≥12 for 2 days indicates a COPD exacerbation event has occurred. |
| Severity of EXACT-PRO for Patients With Baseline EOS>=220/uL | Immediately following first IP up to week 56 | The EXACT-PRO is a 14-item PRO instrument developed to assess the frequency, severity and duration of COPD exacerbations. Respondents are instructed to complete the electronic diary (eDiary) each evening just prior to bedtime and to answer the questions while considering their experiences today.

Number of Participants by Number of COPD Exacerbations Based on EXACT-PRO for Patients With Baseline EOS>=220/uL
The EXACT-PRO is a 14-item PRO instrument developed to assess the frequency, severity and duration of COPD exacerbations. Respondents are instructed to complete the electronic diary (eDiary) each evening just prior to bedtime and to answer the questions while considering their experiences today. The daily EXACT-PRO total score is recorded and has a range of 0-100 with higher scores indicative of greater severity. COPD exacerbation event frequency is calculated based on comparison of the baseline score with daily total scores. An increase of EXACT-PRO total score ≥9 for 3 days or ≥12 for 2 days indicates a COPD exacerbation event has occurred.
