Exciting Developments at Jasper Therapeutics for Asthma Trials

Jasper Therapeutics Moves Forward with Asthma Clinical Trials

Jasper Therapeutics, Inc. (NASDAQ: JSPR), a pioneering clinical-stage biotechnology company, is taking significant strides in its mission to revolutionize treatments for chronic diseases. The company recently announced the clearance of its Clinical Trial Application (CTA) by Health Canada, allowing it to initiate an important Phase 1b/2a clinical trial for its innovative therapy, briquilimab, in the management of asthma.

Understanding Briquilimab and Its Potential

Briquilimab is a specialized monoclonal antibody designed to target the c-Kit (CD117) receptor, which plays a crucial role in various mast cell-driven conditions. This groundbreaking therapy strives to combat diseases such as chronic spontaneous urticaria (CSU), chronic inducible urticaria (CIndU), and asthma itself. The approval from Health Canada marks an essential milestone in the journey of briquilimab, showcasing its potential in treating asthma via a focused clinical challenge study.

Launch of the Clinical Trial

According to Edwin Tucker, M.D., Chief Medical Officer of Jasper, the company is eager to commence the enrollment process for the asthma study soon. The trial is structured as a double-blind, placebo-controlled study, which will include 30 patients across 10 sites located in Canada and the EU. A vital objective of this trial—the demonstration of proof of concept with briquilimab—will help inform future research into broader asthma patient populations.

Research and Development Goals

The study intends to utilize a single dose of 180mg of briquilimab, with assessments focusing on mast cell depletion and recovery, as well as safety and changes in airway responsiveness. The dosing of patients is anticipated to begin in the fourth quarter of 2024, with initial data expected to be shared in the latter half of 2025. Upon hearing the news of the CTA clearance, Ronald Martell, President and CEO, expressed the significance of this achievement in advancing their pipeline targeting mast cell-driven diseases.

Briquilimab's Efficacy and Ongoing Research

One of the defining characteristics of briquilimab is its ability to deplete mast cells effectively, which blocks the inflammatory responses typically seen in allergic reactions, such as asthma. This targeted approach aims to demonstrate the durability and effectiveness of the treatment in clinical settings. Currently, briquilimab has shown a positive safety and efficacy profile across more than 145 participants in various studies, covering conditions from severe combined immunodeficiency (SCID) to acute myeloid leukemia (AML).

The Jasper c-Kit Mouse™ Model

Additionally, Jasper Therapeutics has announced the allowance of a registered trademark for its proprietary model, the Jasper c-Kit Mouse™. This model facilitates direct testing of c-Kit inhibitors, allowing researchers to explore their potential across various diseases while circumventing the limitations present in standard models. As stated by Wendy Pang, M.D., Ph.D., this unique capability enhances clinical translatability in preclinical studies, providing Jasper with a strategic edge as it expands its research avenues.

Commitment to Innovation

Jasper Therapeutics remains committed to developing briquilimab for diseases that challenge patients' quality of life. The emphasis on innovative approaches to treatment underlines the company’s intention to lead in the biotechnology space, especially concerning mast cell-driven conditions. As the company prepares for new clinical trials, it continues to fortify its pipeline, aiming for broad applicability across several diseases.
