Study Endpoints

Primary Endpoints

Annualized rate of moderate or severe acute exacerbation of COPD (AECOPD) in former smokers
Baseline up to End Of Treatment (EOT) (Week 52 for initial randomized participants, 24 to 52 weeks for potential additional randomized former smoker participants)

Annualized rate of moderate or severe acute exacerbation of COPD (AECOPD) over the placebo-controlled treatment period.

Change From Baseline in Itepekimab Pharmacodynamic Normalized Enrichment Score Derived From Former Smokers in Endobronchial Biopsies in Current Smokers With Chronic Obstructive Pulmonary Disease at Week 12
Baseline (Week 0) and Week 12

The NES provides an indication of the difference in gene expression levels for a particular individual before and after treatment for a defined set of genes (or signature). The gene signatures are derived from the genes differentially expressed in endobronchial biopsies, bronchial brushings, and nasal brushings of former smokers. The NES in current smokers, at baseline and at Week 12, are calculated based on the gene signatures of former smokers. Change in NES from baseline indicates that the gene signature is differentially regulated in response to itepekimab, with up- and down-regulated genes changing in their expected directions. No predetermined directionality has been established for this score; therefore, a higher or lower NES does not indicate a better or worse outcome. Baseline was defined as the last available value before first dose of study treatment.
