RC1416 injection for moderate to severe COPD

A Multicenter, Randomized, Double-Blind, Placebo-Controlled Phase II Clinical Study to Evaluate the Efficacy and Safety of RC1416 Injection in Patients With Moderate to Severe Chronic Obstructive Pulmonary Disease (COPD)

Phase 2 Interventional Nanjing RegeneCore Biotech Co., Ltd. · NCT07402551

This study will test whether RC1416 injections given every two weeks for one year can reduce COPD flare-ups and improve breathing in adults with moderate to severe COPD who have had recent exacerbations.

What this trial studies

This multicenter, randomized, double-blind, placebo-controlled Phase II study enrolls adults with moderate to severe COPD and a history of exacerbations. Participants receive RC1416 or placebo by injection every two weeks for 52 weeks while continuing their background COPD treatments. The main outcomes are the annualized rate of moderate or severe COPD exacerbations and the change in post-bronchodilator FEV1 from baseline over the 52-week treatment period. The trial will also measure FeNO, total IgE, blood eosinophils, and TARC to explore biological effects and potential responders.

Who should consider this trial

Good fit: Adults aged 40–85 with documented moderate to severe COPD (post-bronchodilator FEV1/FVC < 0.7 and FEV1 30–<80% predicted), a smoking or other exposure history, mMRC score ≥ 2, and at least two moderate or one severe exacerbation in the prior 12 months are the intended participants.

Not a fit: People with only mild COPD, without recent exacerbations, those outside the specified age or lung-function ranges, or those unable to attend biweekly injection visits are unlikely to receive benefit from this protocol.

Why it matters

Potential benefit: If effective, RC1416 could lower the number of moderate or severe COPD exacerbations and modestly improve lung function over a year.

How similar studies have performed: Some biologic treatments targeting eosinophilic or allergic inflammation have shown benefit in COPD subgroups, but many novel agents remain unproven and published results have been mixed.
