Study Summary

Primary Objective: To investigate effects of SAR440340 (anti-interleukin-33 \[IL-33\] monoclonal antibody \[mAb\]) compared with placebo, on the annualized rate of moderate-to-severe acute exacerbations of COPD (AECOPD) over up to 52 weeks of treatment. * Moderate exacerbations were recorded by the Investigator and defined as AECOPD that require either systemic corticosteroids (such as intramuscular, intravenous or oral) and/or antibiotics. * Severe exacerbations were recorded by the Investigator and defined as AECOPD requiring hospitalization, emergency medical care visit or resulting in death. Secondary Objectives: To investigate effects of SAR440340 compared with placebo, on improving respiratory function, as assessed by pre-bronchodilator forced exploratory volume in 1 second (FEV1). To evaluate effects of SAR440340 compared with placebo, on post-bronchodilator FEV1. To evaluate effects of SAR440340 compared with placebo, on duration from baseline to first moderate or severe AECOPD event. To evaluate effects of SAR440340 compared with placebo, on safety and tolerability.

Primary Outcome

Moderate exacerbations events were recorded by the investigator and defined as AECOPD that require either systemic corticosteroids (such as intramuscular, intravenous or oral) and/or antibiotics. Severe exacerbations events were defined as AECOPD requiring hospitalization, emergency medical care visit or resulting in death. Annualized event rate was the total number of exacerbations that occurred during the treatment period divided by the total number of participant-years treated.
