Announcement
Jasper Therapeutics today reported positive preliminary data from Jasper's ongoing BEACON Phase 1b/2a study of subcutaneous briquilimab in adult participants with CSU. Substantial reductions in UAS7 were reported, with a mean change from baseline at 8 weeks of -26.6 in the 240mg single-dose cohort and multiple dosing regimens at or above 120mg demonstrating UAS7 changes of more than -25 points.
AI Summary
Jasper Therapeutics announced positive preliminary results from its ongoing BEACON Phase 1b/2a study of subcutaneous briquilimab in adults with chronic spontaneous urticaria (CSU). In the study, a single 240mg dose produced a mean reduction of 26.6 points in the Urticaria Activity Score over 7 days (UAS7) at 8 weeks. Additionally, multiple dosing regimens at doses of 120mg and above showed UAS7 reductions of more than 25 points, indicating rapid and significant symptom relief.
The early data also revealed deep and durable clinical responses, with 100% of patients in the 240mg single-dose cohort achieving complete responses (UAS7 = 0) at 8 weeks. These promising results, along with a favorable safety profile, support moving briquilimab forward into a registrational program planned to start in the second half of 2025.
