Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Primary Objective:

Primary population (former smokers cohort):

* 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:

Primary population (former smokers cohort):

* 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

Secondary population (current smokers cohort)

* Estimate the efficacy of itepekimab compared with placebo on the annualized rate of acute moderate or severe COPD exacerbations in current smokers with moderate-to-severe COPD
* Estimate the efficacy of itepekimab compared with placebo on pulmonary function in current smokers with moderate-to-severe COPD
* Estimate the safety and tolerability of itepekimab in current smokers with moderate-to-severe COPD
* Estimate the PK profile of itepekimab in current smokers with moderate to severe COPD
* Estimate immunogenicity to itepekimab in current smokers with moderate-to-severe COPD

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study duration per participant:

* Screening period is 3-5 weeks
* Randomized investigational medicinal product (IMP) treatment period is 52 weeks for first cohort of randomized former smoker participants \[approximately 930\] and cohort of current smokers \[approximately 280\], and 24 to 52 weeks for potential additional randomized former smoker participants
* Post-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.
