REDWOOD CITY, Calif., Nov. 10, 2022 (GLOBE NEWSWIRE) -- Jasper Therapeutics, Inc. (Nasdaq: JSPR), a biotechnology company focused on developing multiple new therapies for the field of stem and cellular medicine, today announced third quarter 2022 financial results and provided a corporate update.

“During our third quarter, we continued to advance multiple clinical programs for our anti-CD117 monoclonal antibody, JSP191,” said Ronald Martell, President and Chief Executive Officer of Jasper Therapeutics. “We presented strong, initial data in Fanconi Anemia at the Inborn Errors Working Party (IEWP) annual conference, demonstrating that a conditioning regimen with JSP191 is safe, well tolerated, and achieved 100% complete donor chimerism, neutrophil, and platelet engraftment in the first two patients. We are very pleased with these positive data which increase our confidence in JSP191’s potential as a targeted conditioning strategy that eliminates the need for radiation or alkylating agents”.

Mr. Martell continued, “Additionally, the FDA’s Fast Track designation granted for JSP191 in Severe Combined Immunodeficiency (SCID) reinforces the large unmet medical need for patients with this serious disease. Along with its previous designations of Orphan and Rare Pediatric Disease for JSP191, the FDA’s Fast Track recognizes JSP191’s potential role in improving clinical outcomes for SCID patients, many of whom are too fragile to tolerate the toxic chemotherapy doses typically used in a transplant. Our clinical development program remains on schedule, and we look forward to initiating a study of JSP191 as a therapeutic in lower-risk myelodysplastic syndromes (MDS) in the first quarter of 2023 and a registrational clinical study in acute myeloid leukemia (AML) and MDS patients undergoing stem cell transplantation by the end of the first quarter of 2023.”

Third Quarter 2022 and Recent Highlights:

  • Announced presentation of data from the Company’s investigator-sponsored study of JSP191 as a conditioning agent in the treatment of Fanconi Anemia at the annual conference of the Inborn Errors Working Party (IEWP), a research group of the European Society of Blood and Marrow Transplantation. The Phase 1/2 clinical trial (NCT04784052) utilizes JSP191 to treat Fanconi Anemia patients with bone marrow failure requiring allogeneic transplant with non-sibling donors.
    • In the data series presented, 100% complete donor chimerism was achieved through six months for the first patient and at one month for the second patient. Neutrophil engraftment was reached on day 11 for both patients and platelet engraftment was achieved on days 9 and 14. JSP191 was cleared by day 9 after dosing and no treatment-related adverse events or toxicities were observed.
  • Announced FDA Fast Track Designation for JSP191 in the Treatment of Patients with Severe Combined Immunodeficiency (SCID) undergoing allogeneic hematopoietic stem cell transplant: To date, JSP191 has been studied in 16 SCID patients in an ongoing multicenter clinical trial with clinical outcome data presented at academic medical conferences.
  • Continued progress on the registrational study of JSP191 in older, transplant-eligible patients with AML/MDS: Jasper held a Type B meeting with the FDA during which a review of the trial comparator arm, population, size, statistical assumptions, and primary endpoints were discussed. The Company agreed with the FDA to submit a trial protocol that will allow a potential initiation of a registrational study in AML and MDS patients undergoing stem cell transplant.

Upcoming clinical and corporate milestones:

  • Initiate a new study of JSP191 as second-line therapy for patients with lower-risk MDS expected to start in the first quarter of 2023
  • Initiate a registrational study in AML/MDS patients undergoing stem cell transplant in the first quarter of 2023

Third Quarter 2022 Financial Results

Cash and Cash Equivalents: Cash and cash equivalents as of September 30, 2022 were $51.0 million compared to $84.7 million as of December 31, 2021. The Company expects current cash and cash equivalents to be sufficient to fund its planned operating and capital expenditures through early 2023.

Research and Development (“R&D”) Expenses: R&D expenses for the quarter ended September 30, 2022 were $9.0 million compared to $7.2 million for the corresponding quarter in 2021. The increase of $1.8 million was primarily due to additional costs associated with advancing our clinical trials, higher research spending and employee-related costs following recent hirings to support the ongoing development of our product candidates.

General and Administrative (“G&A”) Expenses: G&A expenses for the quarter ended September 30, 2022 were $3.7 million compared to $2.9 million for the quarter ended September 30, 2021. The increases were primarily related to employee compensation-related expenses, including stock-based compensation, supporting the growth in our operations and costs associated with our status as a public company.

Net Loss: Net loss for the quarter ended September 30, 2022 was $11.9 million compared to a net loss of $3.4 million for the corresponding quarter in 2021. Net loss includes non-cash income recognized from the decrease in fair values of earnout liability of $0.4 million and common stock warrant liability of $0.2 million for the quarter ended September 30, 2022 compared to non-cash income recognized from the decrease in fair values of earnout liability of $6.2 million and common stock warrant liability of $0.5 million for the quarter ended September 30, 2021.

About JSP191

JSP191 is a humanized monoclonal antibody that blocks stem cell factor receptor signaling leading to the clearance of hematopoietic stem and progenitor cells from the bone marrow. JSP191 is in clinical development as a stem cell transplant conditioning agent where it helps create an empty space for the donor or gene-corrected transplanted stem cells to engraft. While hematopoietic cell transplantation can be curative for patients, its use is limited because standard high-dose myeloablative conditioning is associated with severe toxicities and standard low-dose conditioning has limited efficacy. To date, JSP191 has been evaluated in more than 90 healthy volunteers and patients. Three clinical trials for myelodysplastic syndromes (MDS)/ acute myeloid leukemia (AML), severe combined immunodeficiency (SCID) and Fanconi anemia (FA) undergoing allogeneic transplant are currently enrolling. JSP191 is also planned to enter clinical development as a second-line therapeutic in transfusion-dependent, lower risk MDS patients to preferentially drive recovery of healthy hematopoietic stem cells in order to help restore normal hematopoiesis.

About Jasper Therapeutics

Jasper Therapeutics is a biotechnology company focused on the development of novel curative therapies based on the biology of the hematopoietic stem cell. The company is advancing two potentially groundbreaking programs. JSP191, an anti-CD117 monoclonal antibody, is in clinical development as a conditioning agent that clears hematopoietic stem cells from bone marrow in patients undergoing hematopoietic cell transplantation. It is designed to enable safer and more effective curative allogeneic hematopoietic cell transplants and gene therapies. Clinical study of JSP191 as a novel, disease-modifying, therapeutic for patients with lower risk MDS is also planned to begin in the first quarter of 2023. In parallel, Jasper Therapeutics is advancing its preclinical mRNA hematopoietic stem cell grafts platform, which is designed to overcome key limitations of allogeneic and autologous gene-edited stem cells grafts. Both innovative programs have the potential to transform the field and expand hematopoietic stem cell therapy cures to a greater number of patients with life-threatening cancers, genetic diseases and autoimmune diseases than is possible today.
