Phase 2b3 Study Comparing Subcutaneous Lunsekimig to Placebo in Adults With Eosinophilic COPD Not Controlled by Current Treatment

What this Trial Is About

Researchers are evaluating the efficacy, safety, and tolerability of a subcutaneous drug called lunsekimig compared to placebo in adults aged 40 to 80 years who have inadequately controlled Chronic Obstructive Pulmonary Disease COPD with an eosinophilic phenotype. This Phase 2b3 study aims to better understand how lunsekimig might affect COPD symptoms and exacerbations in this specific group. Participants will be randomly assigned to one of three groups lunsekimig dose regimen A, lunsekimig dose regimen B, or a matching placebo. All treatments are given by subcutaneous injection during a 48-week intervention period. The study includes a screening period up to 4 weeks before treatment and an approximately 8-week follow-up after the intervention, for a total duration of up to 60 weeks. During the study, participants will have regular assessments including lung function tests and symptom questionnaires. Researchers will monitor the annual rate of moderate-to-severe COPD exacerbations as the primary outcome. Secondary measures include changes in lung function and quality of life scores, along with safety evaluations such as monitoring adverse events and laboratory tests. Blood samples will be collected to measure drug levels and antibody responses. Participants are observed throughout the treatment and follow-up periods to assess the effects and tolerability of lunsekimig.
