Company announcement, Inside Information
TURKU, Finland and BOSTON, Nov. 06, 2023 (GLOBE NEWSWIRE) -- Faron Pharmaceuticals Ltd. (AIM: FARN, First North: FARON), a clinical-stage biopharmaceutical company pioneering macrophage reprogramming for effective anticancer immunotherapies, today announces that based on guidance from the U.S. Food and Drug Administration (FDA), hypomethylating agents (HMAs)-refractory or relapsed myelodysplastic syndromes (MDS) has been selected as the initial indication to advance to Phase 2 in the BEXMAB study investigating bexmarilimab in combination with standard of care (SoC).
The BEXMAB study is a multicenter study, taking place in Finland and the U.S., evaluating the safety and efficacy of bexmarilimab, a novel anti-Clever-1 humanized antibody, with SoC in patients with aggressive myeloid leukemias.
The Phase 2 part of the BEXMAB trial will enroll a total of 32 patients with HMA-failed MDS. Patients will be randomized 1:1 between the selected recommended doses for expansion (RDE) of 3 mg/kg or 6 mg/kg bexmarilimab before moving into a Phase 2/3 extension of the study. Data from the first 20 patients (10 per group) will be reviewed for exposure benefit for the two selected dose levels. Post selection of final dosing Faron intends to discuss a potential registrational study plan with the FDA.
“Expansion of the BEXMAB study into Phase 2 provides an opportunity to build on the very promising findings we have already observed among patients treated with bexmarilimab in the earlier stage of the trial,” said Dr. Mika Kontro, Associate Professor, Helsinki University Hospital Comprehensive Cancer Center and Principal Investigator of the BEXMAB trial. “With two good doses now established for further investigation we hope to rapidly generate further, robust data to support the potential of this novel immunotherapy in a patient group with too few treatment options available to them.”
Data from the Phase 1 part of the study have demonstrated that optimal target engagement can be achieved with 3 mg/kg dosing. The highest immune activation, as observed in the accumulation of activated immune cells in patients’ bone marrow, was observed in both 3 mg/kg and 6 mg/kg cohorts. Both dose levels have been safe and well tolerated to date.
The 3 mg/kg and 6 mg/kg doses were selected in accordance with the FDA’s Project Optimus initiative, which aims to reform the paradigms of dose optimization and selection in oncology drug development.
“This is a significant milestone in the development of what we hope will be the first macrophage-targeting immunotherapy for patients with aggressive myeloid leukemias,” said Dr. Markku Jalkanen, Chief Executive Officer of Faron. “The emerging bexmarilimab data from the Phase 1 part of the study have been very encouraging, showing continued efficacy signals and long duration of responses. We believe that bexmarilimab has the potential to improve patient outcomes and improve quality of life for those suffering from MDS, addressing the longstanding unmet medical needs in conditions which have had no new effective treatments in decades.”
Faron recently reported updated, positive data from the Phase 1 part of the BEXMAB trial. Bexmarilimab produced a 50% remission rate in doublet dose cohorts (11 out of 22 patients.) Eight out of 11 patients achieved complete remission in the bone marrow with or without blood count recovery. The highest overall response rate (ORR) of 80% was observed among the previously failed HMA MDS group (4 out of 5 patients). The bexmarilimab / SoC combination continues to be well-tolerated at all tested dose levels with no dose-limiting toxicities. Faron expects to open additional sites in the U.S. and Europe to keep up with the increased recruitment speed.

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 BEXMAB
The BEXMAB study is a Phase 1/2 clinical trial investigating bexmarilimab in combination with standard of care (SoC) in the aggressive hematological malignancies of acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). The primary objective is to determine the safety and tolerability of bexmarilimab in combination with SoC (azacitidine) treatment and to identify the recommended Phase II dose. 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.
