Jasper Therapeutics to Present New Positive Data on Briquilimab Conditioning in Patients with Fanconi Anemia at the 2023 Fanconi Anemia Research Fund Scientific Symposium
- All three Fanconi Anemia patients treated with briquilimab achieved full donor engraftment and full blood count recovery
- Briquilimab was well tolerated without any complications
- Study expansion to Phase 2a is ongoing
The data will be featured in a presentation at the 2023
The ongoing investigator initiated Phase 1/2 clinical trial is evaluating a conditioning regimen that includes briquilimab as a potential treatment for FA patients in bone marrow failure. Utilizing briquilimab, the regimen eliminates the need for busulfan chemotherapy or total body irradiation.
“The updated results from the Phase 1b study, which will be presented at FARF, are very encouraging,” said
The details of the presentation are as follows:

About Briquilimab
Briquilimab (formerly JSP191) is a targeted, 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. Jasper intends to start clinical studies of briquilimab as a primary treatment in Chronic Spontaneous Urticaria and Lower to Intermediate Risk myelodysplastic syndromes (MDS). It is also being studied as a conditioning agent for cell and gene therapies for rare diseases. To date, briquilimab has a demonstrated efficacy and safety profile in 130 dosed subjects 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).
About Fanconi Anemia
Fanconi Anemia (FA) is a rare but serious blood disorder that prevents the bone marrow from making sufficient new red blood cells. The disorder can also cause the bone marrow to make abnormal blood cells. FA typically presents at birth or early in childhood between five and ten years of age. Ultimately, it can lead to serious complications, including bone marrow failure and severe aplastic anemia. Cancers such as acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) are other possible complications. Treatment may include blood transfusions or medicine to create more red blood cells, but a hematopoietic stem cell transplant (HSCT) is currently the only cure.

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 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.
