Jasper Therapeutics (NASDAQ:JSPR) reported Q2 2025 financial results and provided updates on briquilimab, its novel antibody therapy targeting c-Kit. The company reported strong efficacy data in chronic urticaria trials, with 89% complete response rate in CSU patients across 240mg and 360mg single-dose cohorts, and 92% complete response in CIndU patients in the 180mg SPOTLIGHT cohort.

However, the company is investigating anomalous results in two BEACON study cohorts where 11 of 13 patients showed no UAS7 reduction, potentially due to product lot variability.

The planned Phase 2b CSU study is now delayed to mid-2026.

The company is implementing a 50% workforce reduction and will focus exclusively on developing briquilimab for chronic urticaria programs. As part of the restructuring, Dr. Edwin Tucker will step down as Chief Medical Officer, with Dr. Daniel Adelman taking over as Acting CMO effective August 1, 2025.

The company is halting all other clinical and preclinical programs, including the ETESIAN study in asthma, SCID study, and ongoing investigator-sponsored studies. Jasper will concentrate resources on completing the BEACON, SPOTLIGHT and open label extension studies for briquilimab in chronic spontaneous urticaria (CSU) and chronic inducible urticaria (CIndU), where the treatment has shown promising results with rapid, deep, and durable responses.
