News Release Details

• First patient dosed in a sponsored trial of JSP191 conditioning in patients with Fanconi Anemia
• On schedule to initiate a registrational study in AML in the first quarter of 2023
• On schedule to initiate a new study of JSP191 as a therapeutic in second-line therapy for lower-risk, transplant ineligible MDS patients later this year
  

REDWOOD CITY, Calif., Aug. 12, 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 second quarter 2022 financial results and provided a corporate update.

“During our second quarter, we continued to advance multiple clinical programs for our anti-CD117 monoclonal antibody, JSP191, announcing the first patient enrolled in a trial in Fanconi Anemia, advancing our new registration trial in older patients with AML and MDS, advancing our new trial as a therapeutic agent in lower-risk transplant ineligible MDS patients and making progress on a potential BLA filing for the SCID re-transplant population,” said Ronald Martell, President, and CEO of Jasper Therapeutics. “There is a compelling need for a new agent targeting hematopoietic stem cells with enhanced disease control and minimal toxicities. Based on the encouraging data in older patients with AML or MDS we presented earlier this year at the Transplantation & Cellular Therapy (TCT) annual meeting showing direct depletion of diseased stem and progenitor cells, successful donor transplant, reduction or elimination of minimal residual disease, as well as positive feedback from the FDA, we believe we have a clear path forward to initiate a registrational study of JPS191 for transplant eligible, older AML patients. We also believe that this data shows that JSP191 has the potential to be used as a therapeutic agent in patients with low to intermediate risk MDS who are not eligible for stem cell transplant and plan to initiate a clinical study later this year. JSP191 has the potential to significantly improve stem cell disease control and transplantation, and we are hopeful that our progress will lead to a major step forward in providing a new therapy for patients across a spectrum of stem cell-related diseases.”

Second Quarter 2022 and Recent Highlights:

• Announced Treatment of First Patient in Study of JSP191 Conditioning in Patients with Fanconi Anemia: The first patient in the sponsored research of the Center for Definitive and Curative Medicine (CDCM) at the Stanford University School of Medicine for the study of JPS191 as a conditioning agent in the treatment of Fanconi Anemia was dosed in May. In accordance with the sponsored research agreement, Stanford Medicine is conducting a Phase 1/2 clinical trial (NCT04784052) utilizing JSP191 to treat Fanconi Anemia patients in bone marrow failure requiring allogeneic transplant with non-sibling donors.
• Continued progress on the registrational study of JSP191 in older, transplant-eligible patients with MDS or AML: 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 registrational studies in either myelodysplastic syndromes (MDS) or acute myeloid leukemia (AML) patients undergoing stem cell transplant. The Company is finalizing the MDS/AML protocol details and plans to submit to the FDA in the coming months.

Upcoming clinical and corporate milestones:

• Initiate a new study of JSP191 as second-line therapy for transplant ineligible patients with low to intermediate risk MDS expected to start in the second half of 2022
• Initiate the registrational study of JSP191 in MDS or AML patients undergoing stem cell transplant in the first quarter of 2023 with the initial focus on the AML population
  

Second Quarter 2021 Financial Results

Cash and Cash Equivalents: Cash and cash equivalents as of June 30, 2022 were $60.8 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 June 30, 2022 were $8.1 million compared to $5.2 million for the corresponding quarter in 2021. The increase of $3.0 million was primarily due to additional costs associated with advancing our clinical trials, higher research spending and employee-related costs, including stock-based compensation expenses 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 June 30, 2022 were $3.8 million compared to $3.3 million for the quarter ended June 30, 2021. The increases were primarily related to professional fees, 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 June 30, 2022 was $10.4 million compared to a net loss of $8.4 million for the corresponding quarter in 2021. Net loss for the quarter ended June 30, 2022 includes income recognized from the decrease in fair values of common stock warrant liability of $0.8 million and earnout liability of $0.6 million.

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 second half of 2022. 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.
