Summary

This is a Phase 2, multicenter study in adult participants with an acute COPD exacerbation and type 2 inflammation

Inclusion Criteria:

* 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.

Exclusion Criteria:

* 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.

* 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.
* Receipt of any marketed nonbiologic drug that modulates type 2 cytokines 30 days or 5 half-lives prior to randomization, whichever is longer.
* Receipt of any marketed or any investigational biologic for COPD or other diseases within 16 weeks or 5 half-lives prior to randomization, whichever is longer.
* Live, attenuated vaccinations within 4 weeks prior to randomization or planned live, attenuated vaccinations during the trial.
* Treatment with oral corticosteroids and/or hospitalization for an exacerbation of COPD completed less than 4 weeks prior to randomization.

The above inclusion and exclusion criteria are not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.
