This study is an exploratory, two-part, 12-week, Phase 2a study to evaluate the mechanism of action of Itepekimab (anti-IL-33-mAb) and its impact on airway inflammation in former and current smokers with COPD, aged 40 to 70 years. This study consists of participants who have been on a standard-of-care (SoC) mono (long-acting β2-agonist [LABA]) or long-acting muscarinic antagonist [LAMA]), double (inhaled corticosteroid [ICS] + LABA, LABA + LAMA or ICS + LAMA), or triple (ICS + LABA + LAMA) controller therapy for COPD for at least 3 months prior to Screening (Visit 1) with stable dose and regimen for controller therapy for ≥1 month prior to Screening (Visit 1) and during the screening period. Participants will stay on their established controller medications for COPD throughout the duration of the study, with the exception of systemic corticosteroids and/or antibiotics used for acute exacerbation of COPD (AECOPD). The total study duration for each part (Part A and Part B) is approximately 36 weeks: 4-week screening period 12-week treatment period 20-week followup period
