Company overview

Mast Cell Disease Company

Jasper Therapeutics develops briquilimab for chronic mast cell diseases, including chronic spontaneous urticaria, chronic inducible urticaria, and asthma.

Briquilimab Mechanism

Briquilimab is an aglycosylated monoclonal antibody targeting c-Kit/CD117. By blocking stem cell factor from binding to the KIT receptor, it is designed to interrupt mast cell survival signaling and induce mast cell depletion.

CSU Evidence Base

Across the BEACON, SPOTLIGHT, and open-label extension studies, Jasper observed complete responses or disease-control signals in CSU. These results informed selection of two active dosing regimens for the planned Phase 2b study.

Future catalysts

Jasper has resubmitted an updated Phase 2b protocol for briquilimab in CSU to the FDA.

Subject to obtaining additional funding, the company plans to initiate the Phase 2b CSU study in the second half of 2026.
