Exhibit 99.1
Jasper Therapeutics Announces New Positive Briquilimab Data to be Presented at the 2023 Tandem Meetings: Transplantation & Cellular Therapy Meetings of ASTCT and CIBMTR
Three abstracts highlight the safety and efficacy of briquilimab combined with low-toxicity radiation conditioning to achieve full donor engraftment and leukemia disease eradication
| ● | Data demonstrates that briquilimab is safe and well-tolerated as a conditioning agent in older patients, median age 70, with AML/MDS undergoing allogeneic hematopoietic cell transplantation |
| ● | Durable remissions achieved in 8 of the first 12 AML patients treated at one-year follow up |
| ● | Lower than expected rates of severe acute and chronic graft-vs-host disease in 29 AML and MDS patients | |
| ● | Report of 12 study patients treated at a single center who underwent outpatient conditioning and donor cell transplant, which is associated with lower hospital resource use |
REDWOOD CITY, Calif., January 13, 2023 – Jasper Therapeutics, Inc. (Nasdaq: JSPR) (“Jasper” or the “Company”), a biotechnology company developing novel antibody therapies addressing chronic diseases such as urticaria, lower-risk myelodysplastic syndromes (MDS) and stem cell transplant conditioning agents targeting c-Kit, today announced that new positive data for briquilimab (formerly known as JSP191), will be presented at the 2023 Tandem Meetings: Transplantation & Cellular Therapy Meetings of ASTCT and CIBMTR, taking place on February 15-19, 2023 in Orlando, Florida.
Three abstracts, covering data related to the Phase 1 study of briquilimab in combination with fludarabine and low-dose irradiation (Flu/TBI) conditioning in older adults (62 to 79 years) with acute myeloid leukemia (AML) or MDS undergoing allogeneic hematopoietic cell transplant (HCT), will be presented. The studies demonstrate that a regimen of briquilimab plus Flu/TBI leads to successful engraftment of donor blood stem cell without the usual short and long-term toxicities that accompany alternative busulfan-based regimens commonly used in transplant of donor or gene-corrected cells. Based on its mechanism of action, briquilimab is known to potently synergize with radiation, amplifying its stem cell depleting effects without increasing off-target toxicity.
The first abstract demonstrates that briquilimab was safe, well-tolerated, and achieved durable remissions in 8 of 12 of the first treated AML patients. All 8 patients were relapse-free at one-year follow up. Six of 9 patients who entered transplant with detectable AML, a group known to have a poor prognosis with high relapse rates, showed long-term eradication of the AML clones at one-year. In a companion abstract, the total group of 29 AML and MDS patients treated with briquilimab and Flu/TBI demonstrated lower than expected rates of acute and chronic graft-versus-host disease (GVHD). The third abstract, to be presented in the Best Abstract session, evaluated the costs and healthcare utilization of 12 briquilimab plus Flu/TBI study patients who received outpatient conditioning and donor cell transplant at a single study center. During the first 100 days post-procedure there were a total of 7 hospitalizations in the 12 patients, with an overall mean stay of 4 days. These results demonstrate the feasibility and potential significant cost savings of outpatient briquilimab plus Flu/TBI conditioning followed by outpatient donor cell transplant in older patients with AML or MDS.
“Our data presentations at the ASTCT meeting add to the significant body of clinical evidence supporting the safety and clinical potential of briquilimab in a variety of indications and patient types,” said Ronald Martell, President and Chief Executive Officer of Jasper. “While we are focusing our near-term resources on the development of briquilimab for chronic diseases and as a conditioning agent for stem cell transplants addressing rare diseases, we believe these data demonstrate that briquilimab is an agent that can markedly improve the safety and efficacy of stem cell transplants for a wide range of malignant and rare diseases.”

About Briquilimab (formerly known as JSP191)
Briquilimab is a targeted, monoclonal antibody that inhibits the cell-surface receptor c-Kit, also known as CD117. It is currently being evaluated as a primary therapeutic for mast cell diseases such as chronic spontaneous urticaria (CSU), chronic inducible urticaria (CIndU), and allergic asthma, and for lower-risk MDS patients. 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), myelodysplastic syndromes (MDS), Fanconi anemia (FA), and sickle cell disease (SCD). In addition, briquilimab is being advanced as a transformational non-genotoxic conditioning agent for gene therapy.
About Jasper Jasper is a clinical-stage biotechnology company developing novel antibody therapies and stem cell transplant conditioning agents targeting c-Kit (CD117), an important receptor found on stem cells and mast cells. The Company’s lead program is briquilimab, a first-in-class monoclonal antibody being developed as a therapeutic for chronic diseases and as a conditioning agent for stem cell transplants for rare diseases.
