The company’s research is centered on targeting c-Kit, a receptor involved in the survival and development of mast cells and hematopoietic stem and progenitor cells. Jasper’s lead product candidate is briquilimab, formerly known as JSP191, an investigational monoclonal antibody designed to block c-Kit activity. The company has evaluated briquilimab in mast cell-mediated diseases, including chronic spontaneous urticaria, and in conditioning regimens intended to prepare patients for hematopoietic stem cell transplantation or certain gene therapies. These programs remain subject to clinical testing and regulatory review. Founded in 2019 and headquartered in Redwood City, California, Jasper Therapeutics serves the global biopharmaceutical and clinical research markets through its development programs. The company’s activities are focused primarily on advancing briquilimab and related therapies rather than selling commercial products.AI Generated. May Contain Errors.
