Jasper Therapeutics Reports Fiscal 2022 Financial Results and Provides a Business Update

Announced Expansion of Briquilimab (formerly known as JSP191) Development Strategy to Include Chronic Spontaneous UrticariaPresentation of Key Briquilimab Clinical Data, Including Initial Results in Stem Cell Transplant for Sickle Cell Disease and One Year Follow-Up for Acute Myeloid Leukemia Transplant PatientsRaised $101.4 Million Net Proceeds in January 2023 REDWOOD CITY, Calif., March 08, 2023 (GLOBE NEWSWIRE) — Jasper Therapeutics, Inc. (Nasdaq: JSPR) (Jasper), a biotechnology company focused on 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 (MDS) as well as novel stem cell transplant conditioning regimes, today announced results for the fiscal year ended December 31, 2022, and provided a business update. “The fourth quarter of 2022 and recent weeks have been a transformational period for Jasper, during which we announced expansion of briquilimab development to include chronic spontaneous urticaria and secured substantial additional capital to execute on our development plan across the briquilimab franchise,” said Ronald Martell, President and Chief Executive Officer of Jasper. “By focusing on well-characterized opportunities in chronic mast cell diseases and stem cell transplant for rare diseases, we have established clear, and potentially fast, pathways to market. With the substantial resources we obtained through our public offering in January 2023, we are positioned to move rapidly into a clinical trial in chronic severe urticaria and to initiate our chronic lower-risk MDS study, while continuing recruitment in the SCID, Fanconi Anemia and sickle cell disease transplant studies.” “Throughout 2022 and early 2023, a growing body of clinical and scientific data was presented at major medical meetings, consistently validating the potential of briquilimab across five transplant indications: SCID, acute myeloid leukemia, MDS, Fanconi Anemia and sickle cell disease,” continued Mr. Martell. “Together with data recently presented at the Transplantation & Cellular Therapy Meetings of ASTCT and CIBMTR, we have established mechanistic and clinical proof-of-concept rationale for briquilimab’s mechanism of targeting c-Kit, adding to our confidence in briquilimab and its potential to address a variety of patient populations by targeting c-Kit expressed on stem cells and mast cells. We look forward to carrying out our priority development programs for briquilimab as a c-Kit targeting therapeutic in chronic diseases and as a novel conditioning agent for stem cell transplant.” Highlights for Fiscal 2022 and Recent Weeks Announced expansion of briquilimab clinical development to include chronic spontaneous urticariaRaised $101.4 million in estimated net proceeds in January 2023Announced initial positive clinical data from a Phase I/II trial of briquilimab as a conditioning treatment in sickle cell diseaseAnnounced positive follow-up clinical data from investigator-sponsored study of briquilimab conditioning in Fanconi Anemia patientsAppointed industry veteran Vishal Kapoor to Jasper’s board of directorsPresented data supporting ongoing development of briquilimab as transplant conditioning in AML or MDS patients at the 2023 Tandem Meetings: Transplantation & Cellular Therapy Meetings of the ASTCT and CIBMTR 12 out of 12 AML patients achieved donor cell engraftment after conditioning with briquilimab in combination with fludarabine and low dose irradiation, with 8 of 12 patients free from morphological relapse at one yearA subanalysis showed 6 of 12 patients receiving outpatient briquilimab-based conditioning and outpatient donor cell infusion required an inpatient stay through the first 100 days post-transplant, with a mean stay of 4 days among all patients. Fiscal 2022 Financial Results Cash and Cash Equivalents: Cash and cash equivalents as of December 31, 2022 were $38.3 million. With proceeds from its January 2023 public offering and sales through the at-the-market facility in January 2023, we expect cash and cash equivalents to be sufficient to fund our planned operating and capital expenditures through 2024.Research and Development (R&D) Expenses: R&D expenses for the year ended December 31, 2022 were $34.6 million compared to $25.4 million for the year ended December 31, 2021. The increase was primarily due to additional costs associated with advancing our clinical trials and clinical manufacturing expenses. The increase also relates to higher research spending and employee-related costs, including stock-based compensation expenses, following hiring in 2022 to support ongoing development of our product candidates.General and Administrative (G&A) Expenses: G&A expenses for the year ended December 31, 2022 were $16.6 million compared to $11.4 million for the year ended December 31, 2021. The increases were primarily related to professional services fees, insurance expenses and employee compensation-related expenses, including stock-based compensation, supporting the growth in our operations and costs associated with being a public company.Net Loss: For the year ended December 31, 2022, net loss was $37.7 million compared to net loss of $30.6 million for the year ended December 31, 2021. About Briquilimab (formerly known as JSP191) Briquilimab 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 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. For more information, please visit us at www.jaspertherapeutics.com.
