The Combination of APG777 (anti-IL-13) and APG333 (anti-TSLP) Inhibits Central and Local Drivers of Obstructive Airway Disease (ATS 2025) - "Benchmark mAbs dupilumab (anti-IL-4Rα), lebrikizumab (anti-IL-13), and tezepelumab (anti-TSLP) were produced based on publicly available sequences. Consistent with TSLP and IL-13 having distinct roles in mediating obstructive airway disease pathology, administration of APG777+APG333 provided potent and broad inhibition of biomarkers of central inflammation and local airway response in primary human cells. Effects were greater and broader than those observed with benchmarks, suggesting that targeting orthogonal drivers of obstructive airway disease is a promising approach for the treatment of Th2-driven respiratory diseases. These data support the continued development of APG777+APG333 for Th2-driven inflammatory diseases."
