Lunsekimig versus placebo for eosinophilic COPD
Official title: A Phase 2b/Phase 3, Randomized, Double-blind, Placebo-controlled, Multicenter Study, to Investigate the Efficacy and Safety of Lunsekimig in Adult Participants With Inadequately Controlled Chronic Obstructive Pulmonary Disease (COPD) Characterized by an Eosinophilic Phenotype
Run by Sanofi · NCT07190222 · Data updated 2026-11-12
This trial tests whether subcutaneous lunsekimig can help adults 40–80 with inadequately controlled COPD who have a high blood eosinophil count.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 40–80 with physician-diagnosed COPD for ≥1 year, post-bronchodilator FEV1 20–70% predicted and FEV1/FVC <0.70, ≥2 moderate or ≥1 severe exacerbations in the prior year, on ICS+LABA+LAMA for ≥12 weeks, blood eosinophils ≥150 cells/μL, ≥10 pack-year smoking history, and BMI 18–40 kg/m2.
✕Probably not a fit
Patients with asthma or asthma–COPD overlap, other significant pulmonary diseases, long-term high-flow oxygen requirements, or a non-eosinophilic COPD profile are unlikely to benefit from this approach.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a randomized, parallel Phase 2b/Phase 3, three-arm trial comparing subcutaneous lunsekimig with matching placebo during a 48-week treatment period followed by an ~8-week follow-up. Eligible participants undergo screening of up to 4 weeks, are randomized to receive study drug or placebo, and continue regular study visits for dosing and safety assessments over about 60 weeks total. The study enrolls adults with an eosinophilic COPD phenotype who remain symptomatic despite triple inhaled therapy, and it measures efficacy, safety, and tolerability outcomes. All participants receive subcutaneous administrations during the intervention period and are monitored for exacerbations, lung function, and adverse events.
Why it matters
Potential benefit: If successful, lunsekimig could reduce COPD exacerbations and improve symptom control for patients with an eosinophilic phenotype.
How similar studies have gone: Other biologics that target eosinophils in COPD have shown mixed results, with some trials reporting reduced exacerbations in eosinophilic subgroups but no consistent benefit across all studies.
