“We are excited to announce dosing of the first patient in the SPOTLIGHT study in patients with CIndU, our second clinical program evaluating briquilimab in a mast cell-mediated disease,” said
The SPOTLIGHT study is expected to enroll approximately 15 patients across 2 dose cohorts. The primary endpoints are safety and tolerability of briquilimab with secondary endpoints focused on efficacy measures and pharmacokinetics. The study is being conducted at four sites in the EU. Jasper anticipates reporting preliminary data from the SPOTLIGHT study in the second half of 2024.
“c-Kit inhibitors are a promising class of monoclonal therapeutics with demonstrated efficacy in mast cell driven diseases,” said
About Briquilimab
Briquilimab (formerly JSP191) 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. Jasper is currently conducting clinical studies of briquilimab as a treatment in patients with CSU or with CIndU. Briquilimab is also currently in clinical studies as a treatment for patients with LR-MDS and as a conditioning agent for cell therapies for rare diseases. To date, briquilimab has a demonstrated efficacy and safety profile in more than 145 dosed participants and healthy volunteers, with clinical outcomes as a conditioning agent in severe combined immunodeficiency (SCID), AML, MDS, FA, and sickle cell disease (SCD).
About Jasper
Jasper is a clinical-stage biotechnology company developing briquilimab, a monoclonal antibody targeting c-Kit (CD117) as a therapeutic for chronic mast and stem cell diseases such as chronic urticaria and lower to intermediate risk MDS and as a conditioning agent for stem cell transplants for rare diseases such as SCD, FA and SCID. To date, briquilimab has a demonstrated efficacy and safety profile in more than 145 dosed participants and healthy volunteers, with clinical outcomes as a conditioning agent in SCID, AML, MDS, FA, and SCD.

These forward-looking statements include, but are not limited to, statements regarding briquilimab’s potential, including with respect to its potential in mast cell driven diseases such as CSU and CIndU and its potential to serve as an important treatment option for patients suffering from CIndU; Jasper’s expectations regarding its Phase 1b/2a SPOTLIGHT study of subcutaneous briquilimab in CIndU, including the expected enrollment, cohorts and site locations, the expected timing for reporting preliminary data, the expectation that the SPOTLIGHT or BEACON studies will establish proof of concept or help Jasper determine doses and dosing regimens for future registrational studies; and Jasper’s expectations regarding its BEACON study in CSU, including the expectation that Jasper will enroll additional patients in the BEACON study for CSU. These statements are based on various assumptions, whether or not identified in this press release, and on the current expectations of Jasper and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by an investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability.
