Jasper Therapeutics, Inc. (NASDAQ:JSPR) (Jasper), a biotechnology company focused on development of briquilimab, a novel antibody therapy targeting c-Kit (CD117) in mast cell driven diseases such as chronic spontaneous urticaria (CSU) and chronic inducible urticaria (CIndU), today announced that the first patient has been dosed in Jasper's Phase 1b/2a (SPOTLIGHT) clinical study of subcutaneous briquilimab for the treatment of CIndU. The SPOTLIGHT study is evaluating a single administration, at two different dose levels, of subcutaneous briquilimab in adult patients with cold urticaria (ColdU) or symptomatic dermographism (SD).
"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 Edwin Tucker, Chief Medical Officer of Jasper. "As with our BEACON study in CSU, we expect the SPOTLIGHT study to establish proof of concept for the depletion of mast cells by briquilimab in CIndU and help us to determine doses and dosing regimens for future registrational studies. We plan to provide enrollment updates as we progress through the study and anticipate reporting preliminary data in the second half of 2024."
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 Marcus Maurer, M.D., Professor of Dermatology and Allergy at Charité – Universitätsmedizin in Berlin. "As a potent and differentiated c-Kit inhibitor, I believe briquilimab has the potential to serve as an important treatment option for patients suffering from CIndU, and I look forward to enrolling patients into the SPOTLIGHT study and additionally into the BEACON study for CSU."
