Announced Planned Development Expansion of Briquilimab in Chronic Spontaneous UrticariaPresented Positive Follow-up Clinical Data from Investigator-Sponsored Study of Briquilimab Conditioning in Fanconi Anemia Patients at the 2023 Transplantation & Cellular Therapy Meetings of the ASTCT and CIBMTRAnnounced Positive Clinical Data from a Phase I/II Trial of Briquilimab as a Conditioning Treatment in Sickle Cell Disease and Beta ThalassemiaStrengthened the Board of Directors and Management Team with Multiple AppointmentsRaised $101.4 Million Net Proceeds in January 2023

REDWOOD CITY, Calif., May 12, 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 quarter ended March 31, 2023, and provided a business update.

“During our first quarter of 2023, we continued to execute on our expansion of briquilimab development to include chronic spontaneous urticaria, and took steps to strengthen our Board and management team with multiple key leadership appointments,” said Ronald Martell, President and Chief Executive Officer of Jasper. “We also secured substantial additional capital to support our development plans across the briquilimab franchise. During the quarter we also presented positive data at the Transplantation & Cellular Therapy Meetings of ASTCT and CIBMTR, which, together with other recent data, continue to help establish the mechanistic and clinical proof-of-concept rationale for briquilimab’s mechanism of action, 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.”

Key Appointments Made to the Board of Directors and Management Team Industry veteran Vishal Kapoor appointed to the Board of DirectorsDaniel Adelman, M.D. appointed as Acting Chief Medical OfficerDavid Hinds appointed as Senior Vice President, Development OperationsMathew Ford appointed as Vice President, Human Resources Presented 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 sub-analysis 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. Announced positive clinical data from a Phase I/II Trial of briquilimab as a conditioning treatment in sickle cell disease and beta thalassemia All three sickle cell disease participants treated with briquilimab successfully engrafted with neutrophil engraftment within 12-16 daysFirst two participants with peripheral blood chimerism at 60 days after allogeneic stem cell transplant achieved 100% donor myeloid chimerismFirst participant treated had a total hemoglobin level of 13.3 g/dL at five months follow up, increased from 8-9 g/dL at baseline Announced European Union Orphan Drug Designation for Briquilimab as a conditioning treatment for patients prior to receiving a stem cell transplantDe-prioritized Phase 3 development of Briquilimab as a conditioning agent in acute myeloid leukemia or high risk myelodysplastic syndrome patients undergoing stem cell transplantRaised $101.4 million in estimated net proceeds in January 2023

Q1 2023 Financial Results

Cash and Cash Equivalents: Cash and cash equivalents as of March 31, 2023 were $129.4 million, compared to $38.3 million at December 31, 2022. The increase in cash and cash equivalents was due to net proceeds from the Company’s public offering in January 2023 and sales through its at-the-market facility in January 2023. Cash and cash equivalents are expected to be sufficient to fund the Company’s planned operating and capital expenditures through 2024.Research and Development (R&D) Expenses: R&D expenses for the quarter ended March 31, 2023 were $9.8 million compared to $8.2 million for the quarter ended March 31, 2022. The increase was primarily due to additional costs associated with advancing its 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 its product candidates.General and Administrative (G&A) Expenses: G&A expenses for the quarter ended March 31, 2023 were $4.1 million compared to $4.6 million for the quarter ended March 31, 2022. The decrease was primarily related to lower professional services fees and lower insurance expenses.Total Other (Expense) Income, Net: Total other expense, net was $0.3 million for the quarter ended March 31, 2023 compared to total other income, net of $10.6 million for the quarter ended March 31, 2022, primarily due to changes in fair values of common stock warrant liability and earnout liability at the end of the respective quarters.Net Loss: For the quarter ended March 31, 2023, net loss was $14.3 million compared to net loss of $2.2 million for the quarter ended March 31, 2022.

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).
