Annualized rate of moderate-to-severe chronic obstructive pulmonary disease (COPD) exacerbations Timeframe: From Baseline up to 48 weeks The annualized moderate or severe COPD exacerbation rate up to 48 weeks treatment period compared to placebo ### Secondary outcomes 1. Change from baseline in post-Bronchodilator Forced Expiratory Volume in 1 second (post-BD FEV1) Timeframe: From Baseline up to 48 weeks The post-Bronchodilator Forced Expiratory Volume in 1 second is defined as the volume of air exhaled from the lungs in the first second of a forced expiration. 2. Change from baseline in pre-Bronchodilator Forced Expiratory Volume in 1 second (pre-BD FEV1) Timeframe: From Baseline up to 48 weeks The pre-Bronchodilator Forced Expiratory Volume in 1 second is defined as the volume of air exhaled from the lungs in the first second of a forced expiration. 3. Change from baseline in the SGRQ-C total score Timeframe: From Baseline up to 48 weeks The St. George's Respiratory Questionnaire for patients with chronic obstructive pulmonary disease is derived from the St. George's Respiratory Questionnaire (SGRQ) and is designed to measure and quantify health status in adult patients with chronic airflow limitation. A global score ranges from 0 to 100 with lower scores indicating better quality-of-life. 4. SGRQ responder defined as an improvement of ≥4 points in the SGRQ-C total score Timeframe: From Baseline up to 48 weeks 5. Change from baseline in the Chronic airways assessment Test (CAAT) score Timeframe: From Baseline up to 48 weeks The CAAT is an 8-item patient-reported outcome (PRO) measure designed to assess the impact of chronic airways diseases, including COPD, on patients' health status. The CAAT has a scoring range of 0-40, with higher scores indicating a greater impact of the disease on health status. 6. CAAT responder defined as an improvement of ≥2 points in the CAAT total score Timeframe: From Baseline up to 48 weeks 7. Change from baseline in the E-RS:COPD total score Timeframe: From Baseline up to 48 weeks The Evaluating Respiratory Symptoms in Chronic Obstructive Pulmonary Disease (E-RS:COPD) is an 11-item patient-reported outcome (PRO) measure that evaluates the severity of respiratory symptoms in patients with stable COPD. The total score ranges from 0 to 40, with higher scores indicating more severe respiratory symptoms. 8. E-RS:COPD responder defined as an improvement of ≥2 points in the E-RS:COPD total score Timeframe: From Baseline up to 48 weeks 9. Annualized rate of severe COPD exacerbations Timeframe: From Baseline up to 48 weeks 10. Time to first moderate or severe COPD exacerbation Timeframe: From Baseline up to 48 weeks Time to first occurrence of moderate to severe COPD exacerbation up to 48 weeks 11. Time to first severe COPD exacerbation Timeframe: From Baseline up to 48 weeks Time to first occurrence of severe COPD exacerbation up to 48 weeks 12. Incidence of participants with TEAEs, including AESIs, and SAEs Timeframe: From Baseline up to 56 weeks Treatment-Emergent Adverse Events (TEAEs), Adverse events of Special Interest (AESIs), Serious Adverse Events (SAEs) 13. Incidence of potentially clinically significant laboratory abnormalities Timeframe: From Baseline up to 56 weeks 14. Serum concentration of lunsekimig Timeframe: From Baseline up to 48 weeks 15. Incidence and titer of antidrug antibodies (ADAs) Timeframe: From Baseline up to 48 weeks Sources for outcomes Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT07190209) ## Eligibility **Sex** All **Age groups** Adults, Older adults **Minimum age** 40 Years **Maximum age** 80 Years **Healthy volunteers** No ### Inclusion criteria - Between 40 to 80 years of age - Physician diagnosed chronic obstructive pulmonary disease (COPD) ≥1 year - Post-bronchodilator forced expiratory volume in 1 second (post-BD FEV1) ≥ 20% and ≤ 70% of predicted value and FEV1/FVC (forced expiratory volume in 1 second /forced vital capacity) <0.70 - Former or current smokers ≥10 pack-years - Chronic Airways Assessment Test (CAAT) ≥10 - ≥2 moderate or ≥1 severe COPD exacerbations in the prior year - Triple (ICS+LABA+LAMA) COPD therapy ≥12 consecutive weeks - EOS (blood eosinophil count) ≥ 150 cells/μL - 18.0 ≤ Body Mass Index ≤ 40.0 kg/m2 ### Exclusion criteria Participants are excluded from the study if any of the following criteria apply: - Asthma, including pediatric asthma, or asthma-COPD overlap syndrome (ACOS) - Significant pulmonary disease other than COPD - Long-term oxygen therapy >4.0 L/min or requirement of >2.0 L/min to maintain oxygen saturation >88% at rest - Unstable disorder that can impact participants safety or study outcomes - Active or incompletely treated tuberculosis - Current or past malignancies - Concomitant therapies: - long-term macrolides or phosphodiesterase Type 3 (PDE-3) or PDE-4 inhibitors unless on stable therapy for >6 months - any biologic therapy or systemic immunosuppressant within 4 months or 5 half-lives prior to Screening The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial Sources for eligibility Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT07190209) ## Sites - Chandler Clinical Research Trials- Site Number : 8400025Chandler, United StatesRecruiting - Pulmonary Associates - Phoenix - East Bell Road- Site Number : 8400114Phoenix, United StatesRecruiting - Epic Medical Research - Surprise- Site Number : 8400096Surprise, United StatesRecruiting - IMAX Clinical Trials- Site Number : 8400109La Palma, United StatesRecruiting - Long Beach Research Institute- Site Number : 8400027Long Beach, United StatesRecruiting - Downtown L.A.
