Are you struggling with managing symptoms of Chronic Obstructive Pulmonary Disease (COPD)?
This is a Phase 2/3 study to investigate the efficacy, safety, and tolerability of subcutaneous (SC) treatment with lunsekimig compared with placebo in adult participants (aged 40 to 80 years, inclusive) with inadequately controlled Chronic obstructive pulmonary disease (COPD) characterized by an eosinophilic phenotype.
Participation to the study consists of 3 periods:
- Screening period of up to 4 weeks
- Randomized intervention period of approximately 48 weeks
- Follow-up period: Approximately 8 weeks The study duration will be up to 60 weeks.
Would you like to take part?
As a volunteer in a research study, you’ll receive study-related medical care from the study doctor and regular follow-up of your health to monitor the effectiveness of the care you’ll receive. The results of this research will be used to find out if the investigational medication being studied will be of benefit to others struggling with COPD, and whether it will be made widely available to all Canadians trying to manage this condition. Study volunteers are an important part of moving medical care forward.
You may qualify to participate in this study if you:
- Are between 40 to 80 years of age, inclusive
- Have physician diagnosed chronic obstructive pulmonary disease (COPD) for ≥1 year
- Have 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
