Myelodysplastic Syndromes

REDWOOD CITY, Calif., March 19, 2024 (GLOBE NEWSWIRE) -- Jasper Therapeutics, Inc. (Nasdaq: JSPR) (Jasper), a biotechnology company focused on development of briquilimab, a novel antibody therapy targeting c-Kit (CD117) in mast cell driven diseases such as chronic spontaneous urticaria (CSU) and chronic inducible urticaria (CIndU), today announced that the first patient has been dosed in Jasper’s Phase 1b/2a (SPOTLIGHT) clinical study of subcutaneous briquilimab for the treatment of CIndU. The SPOTLIGHT study is evaluating a single administration, at two different dose levels, of subcutaneous briquilimab in adult patients with cold urticaria (ColdU) or symptomatic dermographism (SD). “We are excited to announce dosing of the first patient in the SPOTLIGHT study in patients with CIndU, our second clinical program evaluating briquilimab in a mast cell-mediated disease,” said Edwin Tucker, Chief Medical Officer of Jasper. “As with our BEACON study in CSU, we expect the SPOTLIGHT study to establish proof of concept for the depletion of mast cells by briquilimab in CIndU and help us to determine doses and dosing regimens for future registrational studies. We plan to provide enrollment updates as we progress through the study and anticipate reporting preliminary data in the second half of 2024.” The SPOTLIGHT study is expected to enroll approximately 15 patients across 2 dose cohorts. The primary endpoints are safety and tolerability of briquilimab with secondary endpoints focused on efficacy measures and pharmacokinetics. The study is being conducted at four sites in the EU. Jasper anticipates reporting preliminary data from the SPOTLIGHT study in the second half of 2024. “c-Kit inhibitors are a promising class of monoclonal therapeutics with demonstrated efficacy in mast cell driven diseases,” said Marcus Maurer, M.D., Professor of Dermatology and Allergy at Charité – Universitätsmedizin in Berlin. “As a potent and differentiated c-Kit inhibitor, I believe briquilimab has the potential to serve as an important treatment option for patients suffering from CIndU, and I look forward to enrolling patients into the SPOTLIGHT study and additionally into the BEACON study for CSU.” About Briquilimab Briquilimab (formerly JSP191) 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. Briquilimab is also currently in clinical studies as a treatment for patients with LR-MDS and as a conditioning agent for cell therapies for rare diseases. To date, briquilimab has a demonstrated efficacy and safety pro more than 145 dosed participants and healthy volunteers, with clinical outcomes as a conditioning agent in severe combined immunodeficiency (SCID), AML, MDS, FA, and sickle cell disease (SCD). About Jasper Jasper is a clinical-stage biotechnology company developing briquilimab, a monoclonal antibody targeting c-Kit (CD117) as a therapeutic for chronic mast and stem cell diseases such as chronic urticaria and lower to intermediate risk MDS and as a conditioning agent for stem cell transplants for rare diseases such as SCD, FA and SCID. To date, briquilimab has a demonstrated efficacy and safety pro more than 145 dosed participants and healthy volunteers, with clinical outcomes as a conditioning agent in SCID, AML, MDS, FA, and SCD.

Key highlights Latest readout of the BEXMAB study shows more responding patients and good durability of remission amongst HR HMA-failed MDS patients. 4/5 of the initial Phase 1 HR HMA-failed MDS patients were still alive after eight months of follow-up. While data do not yet allow the precise estimation of median overall survival, the survival benefit seen with the current follow-up already for these 5 first patients is very encouraging. This compares favorably to what has been seen with contemporary comparators. 3 additional HMA-failed HR MDS patients have been enrolled in Phase 1 part, leading to a total of 7 out of 8 patients responding, an overall response rate of 87.5%. Faron will be hosting a virtual webinar to discuss the additional data tomorrow, Tuesday, 19 March at 11.00 EET/9am GMT. TURKU, Finland and BOSTON, March 18, 2024 (GLOBE NEWSWIRE) -- Faron Pharmaceuticals Ltd. (AIM: FARN, First North: FARON), a clinical-stage biopharmaceutical company pursuing a CLEVER approach to reprogramming myeloid cells to activate anti-tumor immunity in hematological and solid tumor microenvironments, today provided further data from patients treated during the Phase 1 part of the ongoing BEXMAB trial that has moved into Phase 2 for higher-risk (HR) myelodysplastic syndrome (MDS) patients failed on previous hypomethylating agent (HMA). Previous BEXMAB study results indicated a high overall response rate (ORR) of 5/5 amongst HR HMA-failed MDS patients, for whom there is no approved treatment. The majority of the initial Phase 1 patients have now been on treatment with bexmarilimab together with azacitidine for more than six months, and only one patient has been lost due to transformation of their HR MDS into acute myeloid leukemia (AML). Out of these initial 5 patients, 4 remain alive after eight months. Normally, patients with relapsed or refractory HR MDS have a median overall survival (mOS) of fewer than six months. The mOS of patients treated in the BEXMAB trial is not yet available but, based on the current data, it is estimated to be significantly higher than traditionally seen with current standard of care (or with current approved treatments). After the already reported 5 HMA-failed HR MDS patients, 3 new HMA-failed HR MDS patients were enrolled, filling the remaining Phase 1 slots. Whilst it is too early to assess these patients for survival or durability, the previously seen high ORR has been corroborated with 2/3 responders. The third patient dropped out of the study early in cycle two due to an unrelated serious adverse event (SAE), bringing the current ORR to 7/8 patients (87.5%) in the HMA-failed HR MDS population. The best responses for these 8 patients are as follows: 1 complete response (CR), 3 marrow complete remissions (mCR), 1 partial response (PR), 2 hematological improvements, and 1 stable disease (SD) that dropped out early due to an unrelated SAE. Mika Kontro, MD, PhD, Associate Professor at the Helsinki University Hospital Comprehensive Cancer Center and Principal Investigator of the BEXMAB trial, said: “We are continuing to see encouraging data from the BEXMAB trial with usually unresponsive patients going into remission after treatment with bexmarilimab and azacitidine. Whilst we don’t have median overall survival rates yet, it is encouraging to see that some patients are alive and, importantly, enjoying a good quality of life even up to 12+ months after treatment initiation. I continue to be very excited about the potential of bexmarilimab to considerably improve outcomes for patients suffering from these aggressive conditions.” Dr. Markku Jalkanen, Chief Executive Officer of Faron, said: “These data are really remarkable and confirm our belief that we may finally have a treatment for this underserved patient population. The data are strongly supportive that a registrational trial would be positive against any contemporary comparator when the final endpoint is survival. We eagerly await completion of the Phase 2 part of the BEXMAB study so we can take these data to the FDA as soon as possible.” For the 5 frontline HR MDS patients with 100% ORR previously reported at the American Society of Hematology (ASH) Annual Meeting last year, mOS has also not yet been reached. For the r/r AML patient cohort reported at ASH, which is bigger in size (n= 18) and more mature in follow-up (median follow-up six months), the mOS is currently estimated to be over 8 months (still subject to change as some patients are still ongoing). The historical mOS for this population is around six months, which means that the current data would support running a registrational trial with mOS also as the endpoint in this population. Faron will be hosting a virtual webinar to discuss these data tomorrow, Tuesday, 19 March, at 11.00 EET/9am GMT. There will be an opportunity to ask questions during the webcast.

The primary objective is to determine the safety and tolerability of bexmarilimab in combination with SoC (azacitidine) treatment. Directly targeting Clever-1 could limit the replication capacity of cancer cells, increase antigen presentation, ignite an immune response, and allow current treatments to be more effective. Clever-1 is highly expressed in both AML and MDS and associated with therapy resistance, limited T cell activation and poor outcomes. About Bexmarilimab Bexmarilimab is Faron's wholly owned, investigational immunotherapy designed to overcome resistance to existing treatments and optimize clinical outcomes, by targeting myeloid cell function and igniting the immune system. Bexmarilimab binds to Clever-1, an immunosuppressive receptor found on macrophages leading to tumor growth and metastases (i.e. helps cancer evade the immune system). By targeting the Clever-1 receptor on macrophages, bexmarilimab alters the tumor microenvironment, reprogramming macrophages from an immunosuppressive (M2) state to an immunostimulatory (M1) one, upregulating interferon production and priming the immune system to attack tumors and sensitizing cancer cells to standard of care. About Faron Pharmaceuticals Ltd. Faron (AIM: FARN, First North: FARON) is a global, clinical-stage biopharmaceutical company, focused on tackling cancers via novel immunotherapies. Its mission is to bring the promise of immunotherapy to a broader population by uncovering novel ways to control and harness the power of the immune system. The Company’s lead asset is bexmarilimab, a novel anti-Clever-1 humanized antibody, with the potential to remove immunosuppression of cancers through reprogramming myeloid cell function. Bexmarilimab is being investigated in Phase I/II clinical trials as a potential therapy for patients with hematological cancers in combination with other standard treatments.
