Jasper Therapeutics Announces First Patient Dosed in a Phase 1 Trial of Briquilimab in Lower-Risk Myelodysplastic Syndrome
REDWOOD CITY, Calif., June 22, 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 diseases such as chronic spontaneous urticaria, lower to intermediate risk myelodysplastic syndromes (LR-MDS) as well as novel stem cell transplant conditioning regimes, today announced that the first patient has been dosed in a Phase 1 trial evaluating briquilimab as second-line therapy in subjects with lower-risk myelodysplastic syndrome.
“The initiation of this trial in LR-MDS represents a significant milestone in our briquilimab development program,” said Ronald Martell, President and Chief Executive Officer of Jasper. “To date, the potential of briquilimab has been clinically assessed across five transplant indications and we are excited to explore its potential as a treatment option for a chronic disease such as LR-MDS. This trial underscores our commitment to improving outcomes and quality of life for patients with rare and chronic diseases driven by mast and stem cells.”
Jeffery Lancet, M.D., Chair of the Department of Malignant Hematology at Moffitt Cancer Center, where the Phase 1 trial is being conducted, added, “LR-MDS patients often face limited treatment options that primarily focus on increasing blood cell production and survival rather than restoring normal blood homeostasis. By directly targeting and depleting the diseased stem cells, briquilimab has the potential to restore bone marrow to a healthier and more functional state, with the ultimate goal of improved long-term outcomes and quality of life. We are excited to test briquilimab in the LR-MDS setting.”
Edwin J. Tucker, M.D., Chief Medical Officer of Jasper, stated, “There is a significant need for therapies for people living with LR-MDS. While certain treatments could be employed to manage the symptoms, they do not typically target diseased cells or offer a comprehensive therapeutic approach. With its compelling therapeutic potential in targeting c-Kit, briquilimab holds great promise in lower-risk MDS and could provide a profound benefit for patients in dire need of new therapies. We are excited to embark on this clinical journey and contribute to the advancement of treatment options for patients with chronic diseases.”
The open-label, single-arm Phase 1 trial will evaluate the safety and tolerability of briquilimab as a second-line therapy in subjects with LR-MDS. The trial will employ a 3+3 dose escalation design to identify the maximum tolerated dose or optimal biologic dose and recommended Phase 2 dose of briquilimab monotherapy as a chronic therapeutic for LR-MDS patients with documented cytopenia such as red blood cell transfusion dependence, thrombocytopenia or neutropenia. The trial will be conducted at Moffitt Cancer Center in Tampa, FL, and is expected to enroll up to 30 patients that will receive briquilimab every 56 days for 4 consecutive cycles.

About Jasper
Jasper is a clinical-stage biotechnology company developing briquilimab, a monoclonal antibody targeting c-Kit (CD117) as a therapeutic for chronic mast and stem cell diseases such as chronic spontaneous urticaria and lower to intermediate risk myelodysplastic syndromes (MDS) and as a conditioning agent for stem cell transplants for rare diseases such as sickle cell disease (SCD), Fanconi anemia (FA) and severe combined immunodeficiency (SCID). To date, briquilimab has a demonstrated efficacy and safety profile in over 130 dosed subjects and healthy volunteers, with clinical outcomes as a conditioning agent in SCID, acute myeloid leukemia (AML), MDS, FA, and SCD. In addition, briquilimab is being advanced as a transformational non-genotoxic conditioning agent for gene therapy. For more information, please visit us at www.jaspertherapeutics.com.
