News Release Details

REDWOOD CITY, Calif., Oct. 09, 2023 (GLOBE NEWSWIRE) -- Jasper Therapeutics, Inc. (Nasdaq: JSPR) (Jasper), a biotechnology company focused on the development of briquilimab, a novel antibody therapy targeting c-Kit (CD117) to address mast cell driven diseases such as chronic spontaneous urticaria (CSU) and chronic inducible urticaria (CIndU), as well as lower to intermediate risk myelodysplastic syndromes (LR-MDS) and novel stem cell transplant conditioning regimens, today announced that it will host a KOL webinar on the potential of briquilimab in chronic urticaria on Wednesday, October 11, 2023 at 8:00 AM Eastern Standard Time.

The event will feature Dr. Stephen Galli, Dr. Marcus Maurer, and Dr. Jeffrey Ravetch who will discuss the current treatment landscape and unmet medical need for patients suffering from chronic urticaria, as well as Jasper’s briquilimab as a potential therapeutic.

Jasper’s leadership team will also provide an overview of upcoming clinical studies which will evaluate briquilimab’s potential as a therapeutic for both CSU patients and CIndU patients. Briquilimab is an unconjugated aglycosylated anti-c-Kit antibody that blocks the interaction of the c-Kit receptor from its ligand, stem cell factor (SCF). This mechanism of action disrupts the critical survival signal, leading to mast cell apoptosis thereby removing the underlying source of the inflammatory response in chronic urticaria.

"We're proud to have assembled a distinguished panel of biologic and clinical experts to provide their invaluable perspective on mast cell biology, on treatment options for mast cell-driven diseases such as chronic urticarias, and on the therapeutic potential of monoclonal antibodies such as briquilimab,” said Ronald Martell, President and Chief Executive Officer of Jasper.  “Mast cell depletion stands at the biologic forefront of mast cell-driven diseases like CSU and CIndU with the potential to provide deep and durable control of disease symptoms. The briquilimab clinical studies in CSU and CIndU are designed to identify the optimal biologic dose and the optimal dosing schedule based on the biology of the mast cell and briquilimab’s unique profile."

Dr. Stephen Galli is Professor of Pathology, Microbiology and Immunology and the Mary Hewitt Loveless, M.D. Professor at Stanford Medicine. Dr. Galli leads the Galli Laboratory at Stanford Medicine, a lab focused on developing and employing innovative approaches to understanding the development and function of mast cells and basophils. He is also a member of the Executive Committee of the Stanford Institute for Immunity, Transplantation and Infection.

Dr. Marcus Maurer is Professor of Dermatology and Allergy and the executive Director of the Institute of Allergology at the Charité – Universitätsmedizin Berlin. Dr. Maurer is board certified in Dermatology and Allergology and is also the Co-Director of Allergology and Immunology at the Fraunhofer Institute for Translational Medicine and Pharmacology ITMP.

Dr. Jeffrey Ravetch is currently the Theresa and Eugene Lang Professor at the Rockefeller University and Head of the Leonard Wagner Laboratory of Molecular Genetics and Immunology. His laboratory has focused on the Fc domain of antibodies and their receptors, establishing their structural and functional diversity and the pre-eminence of FcR pathways in host defense, inflammation and tolerance. His work has been widely extended into clinical applications for the treatment of neoplastic, inflammatory and infectious diseases.

A live question and answer session with management will follow the formal presentations. To register for the event, please click here.

About Briquilimab

Briquilimab (formerly JSP191) is a targeted aglycosylated monoclonal antibody that blocks stem cell factor from binding to the cell-surface receptor c-Kit, also known as CD117, thereby inhibiting signaling through the receptor. This inhibition disrupts the critical survival signal, leading to the depletion of the mast cells via apoptosis which removes the underlying source of the inflammatory response in mast cell driven disease such as chronic urticaria. Jasper intends to start clinical studies of briquilimab as a primary treatment in Chronic Spontaneous Urticaria as well as in Chronic Inducible Urticaria. Briquilimab is also currently in clinical studies as a treatment for patients with Low to Intermediate Risk myelodysplastic syndromes (MDS) and as a conditioning agent for cell and gene therapies for rare diseases. To date, briquilimab has a demonstrated efficacy and safety profile in more than 145 dosed participants and healthy volunteers, with clinical outcomes as a conditioning agent in severe combined immunodeficiency (SCID), acute myeloid leukemia (AML), MDS, Fanconi anemia (FA), and sickle cell disease (SCD).
