Outcome(s)

Primary Outcome

1. Annualized rate of moderate or severe acute exacerbation of COPD (AECOPD) in former smokers [ Time Frame: Baseline up to Week 52 ]
Annualized rate of moderate or severe acute exacerbation of COPD (AECOPD) over the 52-week placebo-controlled treatment period.

Secondary Outcome

1. Change from baseline in pre-bronchodilator (BD) forced expiratory volume in 1 second (FEV1) at Week 52 in former smokers [ Time Frame: Baseline to Week 52 ]
FEV1 is the volume of air exhaled in the first second of a forced expiration as measured by spirometer.

2. Change from baseline in post-BD FEV1 at Week 52 in former smokers [ Time Frame: Baseline to Week 52 ]
FEV1 is the volume of air exhaled in the first second of a forced expiration as measured by spirometer.

3. Change from baseline in pre-BD FEV1 at Week 24 in former smokers [ Time Frame: Baseline to Week 24 ]
FEV1 is the volume of air exhaled in the first second of a forced expiration as measured by spirometer.

4. Time to first moderate or severe AECOPD in former smokers [ Time Frame: Baseline through Week 52 ]
Time to first moderate or severe AECOPD over the 52 week placebo-controlled treatment period.

5. Annualized rate of severe AECOPD in former smokers [ Time Frame: Baseline up to Week 52 ]
Annualized rate of severe AECOPD over the 52 week placebo-controlled treatment period.

6. Time to first severe AECOPD in former smokers [ Time Frame: Baseline through Week 52 ]
Time to first severe AECOPD over the 52-week placebo-controlled treatment period.

7. Annualized rate of corticosteroid-treated AECOPD in former smokers [ Time Frame: Baseline up to Week 52 ]
Annualized rate of corticosteroid-treated AECOPD over the 52-week placebo-controlled treatment period.

8. Change from baseline in Evaluating Respiratory Symptoms in COPD (E-RS:COPD) total score at Week 52 in former smokers [ Time Frame: Baseline to Week 52 ]
The E-RS: COPD is administered as a part of the 14-item EXACT questionnaire and is completed on a daily basis.The 11-item E-RS:COPD assesses severity of respiratory symptoms overall and severity of individual symptoms such as breathlessness, cough and sputum, and chest symptoms The total score of E-RS:COPD ranges from 0 to 40, with higher values indicating more severe respiratory symptoms.

9. Rate of change in post-BD FEV1 (L) from baseline (post-BD FEV1 slope) in former smokers [ Time Frame: Baseline up to Week 52 ]

10. Change from baseline in St. George's Respiratory Questionnaire (SGRQ) total score at Week 52 in former smokers [ Time Frame: Baseline to Week 52 ]
The SGRQ is a 50-item questionnaire designed to measure and quantify health status in adult participants with chronic airflow limitation. A global score ranges from 0 to 100. Scores by dimension are calculated for 3 domains: Symptoms, Activity and Impacts (Psycho-social) as well as a total score. A lower score indicates better quality of life.

11. Proportion of participants with a decrease from baseline of at least 4 points in SGRQ total score at Week 52 in former smokers [ Time Frame: Baseline to Week 52 ]
The SGRQ is a 50-item questionnaire designed to measure and quantify health status in adult participants with chronic airflow limitation. A global score ranges from 0 to 100. Scores by dimension are calculated for 3 domains: Symptoms, Activity and Impacts (Psycho-social) as well as a total score. A lower score indicates better quality of life.

12. Incidence of treatment-emergent adverse events (TEAEs), adverse event of special interests (AESIs), serious adverse events (SAEs), and adverse events (AEs) leading to permanent treatment discontinuation in former smokers [ Time Frame: Baseline up to end of study (Week 72) ]

13. Incidence of potentially clinically significant laboratory test, vital signs, and electrocardiogram (ECGs) abnormalities in former smokers [ Time Frame: Baseline up to end of study (Week 72) ]

14. Functional itepekimab concentrations in serum in former smokers [ Time Frame: Baseline up to end of study (Week 72) ]

15. Incidence of treatment-emergent anti-itepekimab antibodies responses in former smokers [ Time Frame: Baseline up to end of study (Week 72) ]

16. Annualized rate of moderate or severe AECOPD in current smokers [ Time Frame: Baseline up to Week 52 ]
Annualized rate of moderate or severe AECOPD over the 52 week placebo-controlled treatment period.

17. Change from baseline in pre-BD FEV1 at Week 52 in current smokers [ Time Frame: Baseline up to Week 52 ]
FEV1 is the volume of air exhaled in the first second of a forced expiration as measured by spirometer.

18. Incidence of TEAEs, AESIs, SAEs, and AEs leading to permanent treatment discontinuation in current smokers [ Time Frame: Baseline up to end of study (Week 72) ]

19. Incidence of potentially clinically significant laboratory, vital signs, and ECGs abnormalities in current smokers [ Time Frame: Baseline up to end of study (Week 72) ]

20. Functional itepekimab concentrations in serum in current smokers [ Time Frame: Baseline up to end of study (Week 72) ]

21. Incidence of treatment-emergent anti-itepekimab antibodies responses in current smokers [ Time Frame: Baseline up to end of study (Week 72) ]
