• First Patient Dosed in Phase 1 trial of Briquilimab in Lower-Risk Myelodysplastic Syndrome
• Strengthened the Board of Directors and Management Team with Multiple Appointments

REDWOOD CITY, Calif., Aug. 11, 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 (LR-MDS) as well as novel stem cell transplant conditioning regimes, today announced results for the fiscal quarter ended June 30, 2023, and provided a business update.

“During our second quarter, we continued our preparations to begin a study in chronic spontaneous urticaria, which we anticipate initiating in the coming months,” said Ronald Martell, President and Chief Executive Officer of Jasper. “We also dosed the first patient in our Phase 1 trial evaluating briquilimab as second-line therapy in subjects with LR-MDS, and took significant additional steps taken to strengthen our Board and leadership teams. With a strong balance sheet, enhanced organization and a sound development plan, we believe we are well-positioned to advance our priority briquilimab development programs in rare and chronic diseases driven by mast and stem cells.”

Highlights for Q2 2023 and Recent Weeks

• Dosed first patients in a Phase 1 trial of briquilimab in LR-MDS
  • 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 is being 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.
• Key Appointments
  • Scott Brun, M.D. appointed to the Board of Directors
  • Stephen J. Galli, M.D. appointed to Scientific Advisory Board
  • Daniel Adelman, M.D. appointed to Scientific Advisory Board
  • Edwin J. Tucker, M.D. appointed as Chief Medical Officer
  • Patricia Carlos appointed as Senior Vice President of Regulatory and Quality Affairs
  • Annette Marcantonio appointed as Vice President of Clinical Operations

Q2 2023 Financial Results

• Cash and Cash Equivalents: Cash and cash equivalents as of June 30, 2023, were $115.8 million, compared to $38.3 million as of 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 June 30, 2023, were $13.3 million compared to $8.1 million for the quarter ended June 30, 2022. The increase was primarily due to additional costs associated with advancing Jasper’s clinical trials and clinical manufacturing expenses. The increase also relates to higher research spending and employee-related costs following hiring in 2022 and 2023 to support the ongoing development of its product candidates.
• General and Administrative (G&A) Expenses: G&A expenses for the quarter ended June 30, 2023, were $4.5 million compared to $3.8 million for the quarter ended June 30, 2022. The increase was primarily related to higher employee compensation related costs, including stock-based compensation expenses, to support the growth in Jasper’s operations.
• Total Other Income, Net: Total other income, net was $1.7 million for the quarter ended June 30, 2023, compared to total other income, net of $1.6 million for the quarter ended June 30, 2022. Total other income, net, consists of interest income and 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 June 30, 2023, net loss was $16.1 million compared to net loss of $10.4 million for the quarter ended June 30, 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).
