Business context and study results
The randomized, double-blind, placebo-controlled study enrolled 159 participants with COPD, type 2 inflammation, and blood eosinophils of at least 300 cells/µL. Participants received one subcutaneous dose of rademikibart or placebo, in addition to standard of care. The primary endpoint was treatment failure through 28 days; reported topline results describe outcomes through Week 4.
- Treatment failure rate was reduced by 81% versus placebo through Week 4 (p=0.0122).
- New moderate-to-severe COPD exacerbation rate was reduced by 85% through Week 4 (p=0.030).
- New emergency-department visits and hospital admissions for exacerbations were reduced by 100% through Week 4 (p=0.0137).
- Rescue-inhaler use was significantly reduced from Week 2 through Week 7, and COPD symptoms improved significantly at Week 2 (Total Score, p=0.0197).
- FEV1 improvement at Week 4 was 70 mL greater than placebo, described as clinically meaningful; the difference was not statistically significant (p=0.1607).
- Rademikibart was reported as well tolerated, with no new safety signals through study end. The company reported fewer adverse events and serious adverse events in the rademikibart arm than in the placebo arm.
