(MENAFN- GlobeNewsWire - Nasdaq) REDWOOD CITY, Calif., March 30, 2026 (GLOBE NEWSWIRE) -- Jasper Therapeutics, Inc. (Nasdaq: JSPR) (Jasper), a clinical stage biotechnology company focused on development of briquilimab, a novel antibody therapy targeting c-Kit (CD117) to address mast cell driven diseases such as chronic spontaneous urticaria (CSU), chronic inducible urticaria (CIndU) and asthma, today reported results for the fiscal quarter and year ended December 31, 2025 and provided a corporate update. "Briquilimab has demonstrated the potential for a compelling and differentiated profile in both CSU and CIndU, along with proof of concept in asthma," said Jeet Mahal, President and Chief Executive Officer of Jasper.“We are very pleased with the chronic urticaria data we reported in January from the BEACON study as well the open-label extension study, which reaffirmed the potential of briquilimab to drive rapid and durable disease control in patients. We are finalizing dose selection for the Phase 2b portion of our planned Phase 2b/3 study in CSU where we will evaluate two efficacious doses versus placebo to demonstrate the differentiated profile based on briquilimab's unique biological properties. We remain on track to commence patient enrollment in the second half of 2026, pending capital availability.”
Highlights for Fourth Quarter 2025 and Recent Weeks
Jeet Mahal appointed as Chief Executive Officer to lead next phase of clinical growth. Reported positive updated data from briquilimab studies in chronic spontaneous urticaria: 67% of additional patients (n=6) enrolled in Cohort 9.1 (240mg/180mg Q8W) of the BEACON study achieved a complete response at 12 weeks with a mean UAS7 reduction of 31 points, 75% of CSU participants (n=36) enrolled in the open label extension study (180mg Q8W) achieved a complete response or well controlled disease at 12 weeks, With a median duration of follow up of more than 200 days on 63 participants in the open label extension study, KIT related AEs were predominantly low-grade events that resolved while on study, and BEACON and open label extension data sets are now sufficient to select doses for the Phase 2b study of briquilimab in CSU planned to commence in the second half of 2026.
Announced the completion of the Company's internal investigation into the anomalous lack of clinical response observed in the July 2025 BEACON data for cohort 8 (240mg Q8W) and cohort 9 (240mg/180mg Q8W). Results indicated there were no issues with the drug product utilized in the study, and the key opinion leader panel convened generated recommendations to enhance site selection and patient screening criteria going forward. Jasper's internal investigation included: Switching all US patients to a new lot of drug product for the remainder of their doses on study to determine if drug product played a role, A comprehensive review of all manufacturing records, drug handling, site training/ logs and data handling, Recovery and testing by Jasper and independent labs of drug product samples from across the supply chain, A review of all US sites and all US patients, including protocol adherence patient medical histories, patient screening and all pharmacokinetics, pharmacodynamics and efficacy data, and Assembling a KOL panel to review the internal investigation findings, including full patient dossiers, which provided its input and conclusions from the findings.
Reported positive preliminary data from ETESIAN study of briquilimab in asthma: Reductions in airway hyperresponsiveness and suppressed eosinophilic response at both 6 weeks and 12 weeks observed after a single 180mg dose of Briquilimab in the ETESIAN Study, and The positive proof of concept data generated in the ETESIAN study supports further development in the broader asthma population; however, advancing any future clinical studies in asthma would be based on an evaluation of the competitive landscape, the potential for strategic partnerships and capital availability.

About Jasper
Jasper is a clinical-stage biotechnology company focused on developing briquilimab as a therapeutic for chronic mast cell diseases. Briquilimab is a targeted aglycosylated monoclonal antibody that blocks stem cell factor from binding to the cell-surface receptor KIT, thereby inhibiting signaling through the receptor. This inhibition disrupts the critical survival signal, leading to the depletion of the mast cells via apoptosis which removes the underlying source of the inflammatory response in mast cell driven diseases such as chronic urticaria and asthma. Jasper is currently evaluating briquilimab as a treatment in patients with CSU, CIndU and asthma. Briquilimab has a demonstrated efficacy and safety profile in patients and healthy volunteers, with positive clinical outcomes in CSU, CIndU and allergic asthma.
