Jasper Therapeutics Reports Positive Phase 1b Results for Briquilimab in Allergic Asthma
Jasper Therapeutics reported positive preliminary clinical data from Jasper's ETESIAN Phase 1b study of subcutaneous briquilimab in adult participants with allergic asthma. A single subcutaneous 180mg dose of briquilimab demonstrated substantial reductions in sputum eosinophils at both six and twelve weeks, as well as improvements over baseline in FEV1 in both Early Asthmatic Response, EAR, and Late Asthmatic Response, LAR. Significant reductions in serum tryptase were observed, consistent with reductions observed in other briquilimab studies at the 180mg dose level. Briquilimab was well tolerated in the study, demonstrating a favorable safety profile. Jasper also announced the completion of its internal investigation into the anomalous lack of clinical response observed in the July 2025 BEACON data for cohort 8 and cohort 9, where no US patients achieved Complete Response or Well Controlled UAS7 by week 12. Based on the work completed, the additional data from subsequent dosing of the US patients and input from a panel of CSU KOLs, Jasper has concluded that the unexpected efficacy results observed in the US patients was not the result of any issues with the drug product. Rather, it was likely a result of patient selection issues, as it appears that 9 of the 10 patients in question did not have CSU as their symptoms were not mast cell-driven.

Jasper Appoints Jeet Mahal as CEO, Focuses on Chronic Urticaria Treatment
- Leadership Change: Jasper Therapeutics has appointed Jeet Mahal as CEO, succeeding Ronald Martell, who joined in 2022; Mahal brings over 30 years of life sciences experience and will drive the development of briquilimab, enhancing the company's competitiveness in chronic urticaria.
- Clinical Research Update: Jasper will host an investor webinar on January 8, 2026, to present updated data from the BEACON study and open-label extension studies, aiming to boost investor confidence and increase focus on briquilimab.
- Product Development Strategy: Mahal emphasized briquilimab's potential in chronic spontaneous urticaria and inducible urticaria, planning to efficiently complete current studies and lay the groundwork for future development, which is expected to provide more effective treatment options for patients.
- Former CEO Contributions: Ronald Martell successfully pivoted briquilimab's development towards allergic and immunological diseases during his tenure, establishing a foundation for clinical proof of concept that supports the company's future growth.
Jasper Stock Soars Following Positive Results from New Asthma Study
Briquilimab Study Results: Jasper Therapeutics released preliminary data from the ETESIAN Phase 1b study showing that a single 180mg dose of briquilimab significantly reduced sputum eosinophils and improved lung function indicators in adults with allergic asthma, demonstrating a favorable safety profile.
Eosinophil Reduction: Treatment with briquilimab led to substantial decreases in sputum eosinophil levels before and after allergen challenges, indicating its potential effectiveness in managing allergic asthma symptoms.
BEACON Cohort Investigation: Jasper completed an internal investigation into the lack of clinical response in the BEACON study cohorts, concluding that the unexpected results were likely due to patient selection issues rather than problems with the drug itself.
Stock Performance: Following the positive study results, Jasper Therapeutics' shares increased by 8.72%, reaching $1.87 at the time of publication.
