• JSP191 Phase 1b severe combined immunodeficiency (SCID) study data accepted for presentation at the American Society of Hematology (ASH) conference in December 2021
• Phase 1b SCID study resumed enrollment following COVID-19-related delays as a precaution for SCID patients
• Announced non-exclusive research collaboration with Aruvant Sciences, Inc. to evaluate JSP191 in Sickle Cell Disease gene therapy studies
• Announced non-exclusive research collaboration with AVROBIO, Inc. to evaluate JSP191 in Fabry disease and Gaucher disease gene therapy studies
• Receipt of FDA Orphan designation for JSP191 for conditioning treatment prior to hematopoietic stem cell transplantation and Rare Pediatric Disease designation for JSP191 as a conditioning treatment for patients with SCID
• Initiation of a new Phase 1/2 clinical trial with the National Cancer Institute (NCI) to evaluate the use of JSP191 as a targeted, non-toxic conditioning agent in patients with GATA2-related myelodysplastic syndromes
• Successful therapeutic stem cell program in-vitro experiments: engineering of hematopoietic stem cells with mRNA of cell surface protein known to improve stem cell function
• Appointment of Lawrence Klein, Ph.D., and Chris Nolet to the Company’s board of directors

“Our third quarter has been a transformative period for Jasper, during which we became a Nasdaq-listed company, secured $100 million of gross proceeds in new capital, continued to have success in advancing JSP191 in clinical trials, established proof of concept in our research-stage therapeutic stem cell platform and signed two additional corporate partnerships,” said Bill Lis, executive chairman and chief executive officer of Jasper Therapeutics. “As a result, we are now poised for the next stage of success towards transforming the field with upcoming milestones, including: JSP191 AML/MDS top line data in broader patient cohorts with long term follow-up, additional long-term JSP191 data in SCID patients, initiation of a pilot study of JSP191 in autoimmune disease, in-vivo proof of concept data in our therapeutic stem cell program using mRNA cell engineering, initiation of corporate partner gene therapy studies as well as enrollment into academic partner studies across multiple indications.”

Third Quarter 2021 Financial Results

• Cash and Cash Equivalents: Cash and cash equivalents as of September 30, 2021, were $100.9 million. The Company expects current cash and cash equivalents to be sufficient to fund its planned operating and capital expenditures through mid-2023.
• Research and Development (“R&D”) Expenses: R&D expenses for the three and nine months ended September 30, 2021 were $7.2 million and $16.8 million, respectively as compared to $4.5 million and $11.2 million, respectively, for the same periods in 2020. The increases were primarily due to additional costs associated to advancing our clinical trials and clinical manufacturing expenses. The increases also relate to higher employee headcount to support ongoing development of our product candidates.
• General and Administrative (“G&A”) Expenses: G&A expenses for the three and nine months ended September 30, 2021 were $2.9 million and $8.0 million, respectively, as compared to $1.5 million and $3.5 million, respectively, for the same periods in 2020. 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 being a public company.
• Net Loss: For the third quarter of 2021, net loss was $3.4 million compared to the net loss of $10.8 million for the third quarter of 2020, and for the nine months ended September 30, 2021, net loss was $21.6 million compared to the net loss of $21.7 million for the nine months ended September 30, 2020.

About JSP191

JSP191 is a humanized monoclonal antibody in clinical development as a conditioning agent that blocks stem cell factor receptor signaling leading to clearance of hematopoietic stem cells from bone marrow, creating an empty space for 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. Two clinical trials for myelodysplastic syndromes (MDS)/acute myeloid leukemia (AML) and severe combined immunodeficiency (SCID) are currently enrolling.

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 a hematopoietic cell transplantation. It is designed to enable safer and more effective curative allogeneic hematopoietic cell transplants and gene therapies. In parallel, Jasper Therapeutics is advancing its preclinical mRNA engineered hematopoietic stem cell (eHSC) platform, which is designed to overcome key limitations of allogeneic and autologous gene-edited stem cell 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.
