REDWOOD CITY, Calif., Nov. 07, 2024 (GLOBE NEWSWIRE) — Jasper Therapeutics, Inc. (Nasdaq: JSPR) (Jasper), a clinical stage biotechnology company focused on development of briquilimab, a novel antibody therapy targeting c-Kit (CD117) to address mast cell driven diseases such as chronic spontaneous urticaria (CSU), chronic inducible urticaria (CIndU) and asthma, today reported results for the fiscal quarter ended September 30, 2024, provided a corporate update and announced the closure of Jasper’s legacy clinical study in lower-risk myelodysplastic syndromes (LR-MDS).
“We achieved several significant milestones in our mast cell development programs in recent months, highlighted by positive initial data from our SPOTLIGHT study in CIndU,” said Ronald Martell, President and Chief Executive Officer of Jasper. “We were very excited to present our first dataset evaluating briquilimab in a mast cell disease, which showed that over 90% of patients treated in the 40mg and 120mg dose cohorts achieved a clinical response, with no serious adverse events (SAEs) and no grade 3 or higher adverse events (AEs) reported. We also made significant progress advancing our development programs in chronic urticaria and asthma with the addition of higher dose cohorts in the BEACON and SPOTLIGHT studies as well as the attainment of regulatory clearance in Canada and the EU for our asthma challenge study. We are looking forward to our next major milestone with the presentation of initial data from the BEACON study expected during the week of January 6th, 2025.”
Highlights for Third Quarter 2024 and Recent Weeks
- Reported preliminary data from the ongoing SPOTLIGHT Phase 1b/2a study of subcutaneous briquilimab in adult participants with cold urticaria (ColdU) or symptomatic dermographism (SD), the two most prevalent sub types of CIndU.
- 14 of 15 participants (93%) enrolled in the 40mg (n=3) and 120mg (n=12) dose cohorts of the study achieved a clinical response within the 6-week preliminary analysis period following administration.
- In the 120mg dose cohort, 10 of 12 participants (83%) experienced a complete response (CR), and 1 participant experienced a partial response (PR).
- Briquilimab was well tolerated in the study, with no serious adverse events (SAEs) and no grade 3 or higher adverse events (AEs) reported.
- In alignment with Jasper’s clinical development plan, Jasper obtained regulatory clearance to enroll a 180mg dose cohort (n=12) in the SPOTLIGHT study, which is open and enrolling patients.
- Jasper continues to expect to present full data from the study, including the 180mg cohort, in the first half of 2025.
- Announced regulatory clearance in the US and the EU to further expand the BEACON study in CSU by adding a 360mg single-dose cohort (n=4); patient enrollment in this cohort has completed. Jasper continues to plan to report initial data from all doses of the BEACON study up through 240mg during the week of January 6th, 2025. Data from the recently added 360mg single-dose cohort is expected to be reported later in the first half of 2025.
- Announced commencement of an open-label extension study in chronic urticarias that will roll over patients from the BEACON and SPOTLIGHT studies upon completion of their initial follow up period.
- Announced that regulatory authorities in Canada, and more recently, the EU, have cleared Jasper’s Clinical Trial Application (CTA) for a Phase 1b/2a asthma challenge study evaluating briquilimab in asthma. The Phase 1b/2a study in asthma is a single dose double-blind, placebo-controlled study that is expected to enroll 30 patients across as many as 10 sites in Canada and the EU with a key objective of demonstrating proof-of-concept in asthma utilizing a therapeutic dose to inform future trials in the broader asthma population.
- Patient enrollment in the study has commenced and dosing is expected to begin in the fourth quarter of 2024.
- Jasper expects to present initial data from the study in the second half of 2025.
- Announced that the Phase 1 open label trial evaluating briquilimab as a second-line therapy in patients with LR-MDS demonstrated that briquilimab was able to deplete diseased hematopoietic stem cells (HSCs) and was well-tolerated by patients without exacerbating pre-existing anemia, neutropenia or thrombocytopenia. The reduction in diseased HSCs, however, did not ultimately translate into an improvement in hematopoiesis for patients, and as a result Jasper has elected to discontinue development in the indication. Data from the study are expected to be presented at a future medical conference.
- Presented preclinical briquilimab data at the American College of Allergy, Asthma & Immunology (ACAAI) Annual Scientific Meeting.
Third Quarter 2024 Financial Results
- Cash and cash equivalents as of September 30, 2024, totaled $92.5 million.
- Research and development expenses for the quarter ended September 30, 2024, were $14.5 million, including stock-based compensation expenses of $0.6 million.
- General and administrative expenses for the quarter ended September 30, 2024, were $5.4 million, including stock-based compensation expenses of $1.4 million.
- Jasper reported a net loss of $18.6 million, or basic and diluted net loss per share attributable to common stockholders of $1.24, for the quarter ended September 30, 2024.
About Briquilimab
Briquilimab is a targeted aglycosylated 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. This inhibition disrupts the critical survival signal, leading to the depletion of the mast cells via apoptosis which removes the underlying source of the inflammatory response in mast cell driven diseases such as chronic urticaria. Jasper is currently conducting clinical studies of briquilimab as a treatment in patients with CSU or with CIndU and is initiating a clinical study in patients with asthma. Briquilimab is also currently in clinical studies as a conditioning agent for cell therapies for rare diseases. To date, briquilimab has a demonstrated efficacy and safety profile in more than 160 dosed participants and healthy volunteers, with clinical outcomes in CIndU, and as a conditioning agent in severe combined immunodeficiency (SCID), acute myeloid leukemia (AML), myelodysplastic syndromes (MDS), Fanconi anemia (FA), and sickle cell disease (SCD).
