Primary Objective: Evaluate the efficacy of itepekimab compared with placebo on the annualized rate of acute moderate-or-severe COPD exacerbations in former smokers with moderate-to-severe COPD Secondary Objectives: * Evaluate the efficacy of itepekimab compared with placebo on pulmonary function in former smokers with moderate-to-severe COPD * Evaluate the efficacy of itepekimab compared with placebo on occurrence of acute exacerbation of COPD (AECOPD) in former smokers with moderate-to-severe COPD * Evaluate the efficacy of itepekimab compared with placebo on severe AECOPD in former smokers with moderate-to-severe COPD * Evaluate the efficacy of itepekimab compared with placebo on corticosteroid-treated AECOPD in former smokers with moderate-to-severe COPD * Evaluate the efficacy of itepekimab compared with placebo on respiratory symptoms in former smokers with moderate-to-severe COPD * Evaluate the efficacy of itepekimab compared with placebo on Forced Expiratory Volume in 1 second (FEV1) slope in former smokers with moderate-to-severe COPD * Evaluate the efficacy of itepekimab compared with placebo on health-related quality of life (HRQoL) as assessed by St. George's Respiratory Questionnaire (SGRQ) in former smokers with moderate-to-severe COPD * Evaluate the safety and tolerability of itepekimab in former smokers with moderate-to-severe COPD * Evaluate the pharmacokinetic (PK) profile of itepekimab in former smokers with moderate-to-severe COPD * Evaluate immunogenicity to itepekimab in former smokers with moderate-to-severe COPD
The study duration per participant: * Screening period is 3-5 weeks * Placebo-controlled treatment period is 52 weeks for first approximately 960 randomized participants, and 24 to 52 weeks for potential additional randomized participants * Post-investigational medicinal product (IMP) treatment follow-up period is 20 weeks for participants not transitioning to the extension study LTS18133 Note: A long-term, double-blinded extension study (LTS18133) will be implemented to allow participants in this study to continue receiving active IMP for an additional period. Only participants completing their End-of-Treatment (EOT) visit per this study protocol will be offered to participate in the LTS18133 study.
