Jasper Therapeutics, Inc. (NASDAQ:JSPR) (Jasper), a clinical stage biotechnology company focused on development of briquilimab, a novel antibody therapy targeting c-Kit (CD117) to address mast cell driven diseases such as chronic spontaneous urticaria (CSU), chronic inducible urticaria (CIndU) and asthma, today announced that Health Canada has cleared the Company's Clinical Trial Application (CTA) for a Phase 1b/2a asthma challenge study evaluating briquilimab in asthma.
The Phase 1b/2a study in asthma is a single dose double-blind, placebo-controlled study that is expected to enroll 30 patients across as many as 10 sites in Canada and the EU with a key objective of demonstrating proof-of-concept in asthma utilizing a therapeutic dose to inform future trials in the broader asthma population. The study will be conducted utilizing a single 180mg dose of subcutaneous briquilimab and key assessments will be both early and late asthmatic response, changes in airway hyperresponsiveness, mast cell depletion and recovery and safety. Jasper expects to commence dosing patients in the fourth quarter of 2024 and to report initial data in the second half of 2025.
