Connect Biopharma Holdings Limited has announced new data supporting its investigational anti-interleukin-4-receptor alpha (IL-4Rα) antibody, rademikibart, at the European Respiratory Society (ERS) Congress 2025. The data demonstrated rapid and significant improvements in lung function and asthma control among patients, with the greatest benefits observed in those with elevated baseline levels of type 2 inflammatory markers. The results also showed a significant reduction in annualized exacerbations in patients with one or more elevated type 2 inflammatory markers at baseline. These findings support the ongoing Phase 2 Seabreeze STAT studies evaluating rademikibart for acute exacerbations in asthma and COPD. Connect Biopharma expects to report topline data from these studies in the first half of 2026. The company has made the presentations available on its website under the publications and presentations section.
