Jasper Therapeutics Reports Fourth Quarter and Full-Year 2024 Financial Results and Provides Corporate Update
Globe Newswire 27-Feb-2025 8:00 AM
REDWOOD CITY, Calif., Feb. 27, 2025 (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, 2024 and provided a corporate update.
"The past year has been a transformational period for Jasper, highlighted by positive data readouts from the BEACON study in CSU and the SPOTLIGHT study in CIndU, our first two clinical studies evaluating Briquilimab in mast cell diseases," said Ronald Martell, President and Chief Executive Officer of Jasper. "Data from both studies demonstrate the ability of briquilimab to drive rapid and deep response profiles in patients with chronic urticaria, along with the potential for a favorable and differentiated safety profile. We believe the preliminary results from the BEACON study support advancing briquilimab into a pivotal program in CSU beginning with an operationally adaptive Phase 2b study that we expect to commence later this year. Final dose selection for the Phase 2b study will be further informed by a substantial array of additional clinical data at doses of 180mg and higher coming mid-year, including results from approximately 40 additional patients in the BEACON study and SPOTLIGHT study, as well as results from approximately 30 patients in the open-label extension study."
Highlights for Fourth Quarter 2024 and Recent Weeks
Reported positive preliminary data from the ongoing BEACON Phase 1b/2a study of subcutaneous briquilimab in adult participants with CSU. Rapid onset of deep and durable clinical responses were observed across multiple dosing cohorts.
Multiple dosing regimens =120mg demonstrating weekly urticaria activity score (UAS7) improvement of more than 25 points.
Clinical responses observed as early as 1 week following first dose with complete responses achieved as early as week 2.
Briquilimab has been well tolerated in the study, with adverse events (AEs) possibly related to c-Kit blockade being infrequent and generally limited to low grade events which resolved while still on study. No dose delays or discontinuations due to c-Kit related AEs were reported.
Preliminary data support advancing briquilimab into a registrational program in CSU, beginning with a Phase 2b operationally adaptive study expected to commence in the second half of 2025.
Obtained regulatory clearance to commence enrollment in the BEACON study cohorts evaluating 240mg Q8W and a 240mg loading dose followed by 180mg Q8W.
Jasper expects to report data around mid-year 2025 from 4 cohorts: the 240mg single dose cohort (4 additional patients), 240mg Q8W cohort (8 patients), 240mg followed by 180mg Q8W cohort (8 patients), and the 360mg single dose cohort (8 patients).
Reported positive preliminary data from the ongoing SPOTLIGHT Phase 1b/2a study of subcutaneous briquilimab in adult participants with cold urticaria (ColdU) or symptomatic dermographism (SD), the two most prevalent sub types of CIndU.
14 of 15 participants (93%) enrolled in both dose cohorts included in the data-cut (n=15) achieved a clinical response within the 6-week preliminary analysis period following administration.
In the 120mg dose cohort, 10 of 12 participants (83%) experienced a complete response (CR), and 1 participant experienced a partial response (PR).
Briquilimab has been well tolerated in the study, with no serious adverse events (SAEs) and no grade 3 or higher AEs reported.
Commenced enrollment in the 180mg cohort of the SPOTLIGHT study. Jasper expects to report additional data from the study, including the 180mg cohort (n=12), in the first half of 2025.
Commenced an open-label extension (OLE) study in chronic urticarias that will roll over patients from the BEACON and SPOTLIGHT studies upon completion of their initial follow up period. Patients enrolled in the OLE study will receive 180mg dose briquilimab on a Q8W schedule.
Jasper expects to report initial data from approximately 30 patients enrolled in the OLE study around mid-year 2025.
Announced five poster presentations and an oral presentation of briquilimab clinical and preclinical data at the AAAAI 2025 Annual Meeting, being held February 28 - March 3, 2025, in San Diego, CA. The oral presentation and one of the poster presentations will include additional follow-up from patients included in Jasper's January 8th, 2025, disclosure of preliminary data from the Phase 1b/2a BEACON trial.
Announced dosing of first patient in the ETESIAN Phase 1b/2a clinical challenge study evaluating a single administration of subcutaneous briquilimab in patients with asthma.
ETESIAN study is a single dose double-blind, placebo-controlled challenge study that is expected to enroll approximately 30 patients across as many as 7 sites in Canada with a key objective of demonstrating proof-of-concept in asthma utilizing a potential therapeutic dose to inform future trials in the broader asthma population.
The study will be conducted utilizing a single 180mg dose of subcutaneous briquilimab and key assessments will include both early and late asthmatic response, changes in airway hyperresponsiveness, mast cell depletion and recovery, and safety.
Jasper expects to report initial data in the second half of 2025.

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 c-Kit, also known as CD117, 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 conducting clinical studies of briquilimab as a treatment in patients with CSU, CIndU or asthma. Briquilimab has a demonstrated efficacy and safety profile in patients and healthy volunteers, with positive clinical outcomes in CSU and CIndU.
