Outcome Measures
Primary Outcomes (1)
Treatment failure rate
Treatment failure is defined as death due to any cause, (re)admission to a hospital for COPD, ED (re)visit or unscheduled medical visit for worsening of COPD symptoms, or the necessity to intensify pharmacologic treatment (including second course of systemic steroids for COPD exacerbation) within 28 days after randomization.
28 days
Secondary Outcomes (7)
Rate of new moderate and severe COPD exacerbations over the 28 days after randomization
28 days
Time to the first new moderate or severe COPD exacerbation in the 28 days after randomization
28 days
Mean change from baseline (CFB) in EXACT-PRO score
Week 1, Week 2, and Week 4
Absolute CFB in post-BD FEV1 at Day 3, Week 1, and Week 4
Day 3, Week 1, and Week 4

Eligibility Criteria
You may qualify if:
- Physician-diagnosed COPD with duration of ≥12 months.
- Must have experienced at least 1 COPD exacerbation requiring the use of systemic corticosteroids.
- Participants in a stable condition must have a documented historical peripheral blood eosinophil count of ≥250 cells/μL and/or FeNO ≥ 25 ppb.
- Current or former smoker with a history of smoking of ≥10 pack-years.
- Current acute COPD exacerbation requiring an urgent healthcare visit for treatment.
- Peripheral blood eosinophil count of ≥300 cells/μL as part of the assessment of the index acute COPD exacerbation.
- Requires systemic corticosteroids as standard of care treatment in the urgent healthcare setting for the current acute COPD exacerbation.
You may not qualify if:
- Regular use of immunosuppressive medication 12 weeks or 5 half-lives prior to randomization, whichever is longer.
- Current diagnosis or a history of asthma, according to the Global Initiative for Asthma; or participants with a current diagnosis or history of Asthma COPD Overlap Syndrome.
- Other respiratory disorders that might compromise the safety of the participant or affect the interpretation of the results.
- Unstable ischemic heart disease, cardiomyopathy, heart failure (New York Heart Association Class III or IV), uncontrolled hypertension. Cardiac arrhythmias including paroxysmal atrial fibrillation.
- Transient ischemic attack or stroke \<6 months from Screening Visit; hospitalization for any cardiovascular or cerebrovascular event \<6 months from Screening Visit.

- Chronic treatment with long-term oxygen therapy (LTOT) or nocturnal oxygen therapy required for \>15 hours a day.
- Participants on long-term macrolide.
- Current acute COPD exacerbation for which SoC was started \>48 hours prior to Screening.
- A recent chest X-ray or computed tomography (CT) scan at Screening reveals evidence of clinically significant abnormalities not believed to be due to the presence of COPD, or a clinically significant pulmonary infection identified by chest X-ray (CT scan).
- Female participant who is pregnant, lactating or breast-feeding, or has a positive urinary β-hCG test prior to randomization.
