Inside information
TURKU, FINLAND / BOSTON, MA - Faron Pharmaceuticals Oy ( AIM: FARN, First North: FARON ), a clinical stage biopharmaceutical company focused on tackling difficult-to-treat cancers and inflammation via precision immunotherapy, today announces that dosing has moved to the second level in the Company's Phase I/II BEXMAB study. BEXMAB is investigating bexmarilimab, Faron's wholly-owned precision immunotherapy asset, in combination with standard of care (SoC) in multiple hematological malignancies.
The primary objective of the BEXMAB study is to determine the safety and tolerability of bexmarilimab in combination with SoC (azacitidine and venetoclax) treatment and to identify the recommended Phase II dose. Secondary objectives include characterizing bexmarilimab's pharmacokinetic profile in combination with SoC treatment and assessing its immunogenicity.
The first stage of the BEXMAB study comprises four predefined dose levels commencing at bexmarilimab 1mg/kg. Following the announcement of patient dosing commencement in June 2022, five patients have received 1mg/kg weekly dosing of bexmarilimab with no dose-limiting toxicities or safety concerns observed. These data warrant escalation of dosing with bexmarilimab to the second predefined weekly dosing level of 3mg/kg.
All first stage cohort patients are alive. The longest treated patient at three cycles has revealed partial response as observed by reduced cancer activity with reduced blast (cancer cell) counts and normalised blood cell counts.
Initial data from patients dosed with bexmarilimab also show a significant reduction in levels of soluble Clever-1 protein in the blood of treated patients. Earlier research from the Company's MATINS study, investigating the safety and efficacy of bexmarilimab monotherapy in solid tumor cohorts, indicates that this soluble form of the Clever-1 protein is a direct inhibitor of T cells and could have an immunosuppressive effect in all locations of the body, therefore decreasing the general immune capacity of patients. This initial finding will be followed in all patients throughout the BEXMAB study.
"The escalation of dosing with bexmarilimab to the second level in the BEXMAB study, following confirmation of no dose limiting toxicities, is an encouraging early signal as we pursue this immunotherapy's potential to treat hematological malignancies in the combination setting," said Marie-Louise Fjällskog, M.D., Ph.D., Chief Medical Officer of Faron. "We have also observed an early indicator of clinical benefit in the first patient dosed, alongside the observation of a reduction in levels of immunosuppressive soluble Clever-1 protein in the blood of treated patients. We look forward to generating further data as the trial progresses to help determine the optimal dose of bexmarilimab to take forward into Phase II."
"The safety findings in the trial's first five patients, showing no dose-limiting toxicities or safety concerns with the 1mg/kg weekly dosing of bexmarilimab, is a very encouraging step supporting the scientific rationale to combine bexmarilimab and azacitidine with the aim to activate an immune response to control the disease," said Mika Kontro, M.D., Ph.D., Helsinki University Hospital Comprehensive Cancer and Principal Investigator of the BEXMAB trial. "The initial safety data that we gather will inform the potential for expansion into a Phase II study in combination with azacitidine. The study may now also progress to include first-line triplet therapy with bexmarilimab, azacitidine and venetoclax in newly diagnosed acute myeloid leukemia patients not benefitting from conventional chemotherapy ."
"The BEXMAB study is off to a great start, and we are eagerly waiting to see the first data from the triplet therapy, where bexmarilimab could become a cornerstone of first-line treatment in newly diagnosed AML patients," said CEO Markku Jalkanen. "We wish to thank our investigators, and especially patients, for the wonderful start of this trial, and their commitment in helping to find new treatments for this grave condition."
"For investors these are very encouraging - though early - results. We should remember that AML is an extremely serious indication with over 90% mortality in five years and all new approaches that can change this are urgently needed," said Yrjö Wichmann, Faron's VP Funding and IR. "Earlier we were able to show clinical benefit in solid tumor cancers and now we have positive indication also in blood cancers, in which the Clever-1 target molecule is expressed directly on the surface of the cancer cells themselves. Additionally, as AML is a very serious condition, the route to regulatory approval can be faster if results are exceptional."
Further details of the BEXMAB study are available on ClinicalTrials.gov (Identifier: NCT05428969).
Faron will also host a special event in December where further details of the BEXMAB study will be presented together with current treatment practices for hematological malignancies.

About Bexmarilimab
Bexmarilimab is Faron's wholly-owned, investigative precision immunotherapy with the potential to provide permanent immune stimulation for difficult-to-treat cancers through targeting myeloid cell function. A novel anti-Clever-1 humanised antibody, bexmarilimab targets Clever-1 positive (Common Lymphatic Endothelial and Vascular Endothelial Receptor 1) tumour associated macrophages (TAMs) in the tumour microenvironment, converting these highly immunosuppressive M2 macrophages to immune stimulating M1 macrophages. As an immuno-oncology therapy, bexmarilimab has potential as a single-agent therapy or in combination with other standard treatments including immune checkpoint molecules in both solid tumors and hematologic malignancies. Beyond immuno-oncology, it offers potential in infectious diseases, vaccine development and more.
About BEXMAB
The BEXMAB study is a first-in-human open label phase I/II clinical trial investigating bexmarilimab in combination with standard of care (SoC) in aggressive hematological malignancies including acute myeloid leukemia (AML) and myelodysplatic 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. Based on initial safety data, there is potential for expansion to include a first line triplet therapy of bexmarilimab, azacitidine and venetoclax in newly diagnosed AML patients who are not able to tolerate chemotherapy. Clever-1 is highly expressed in both AML and MDS and associated with therapy resistance, limited T cell activation and poor outcomes. Directly targeting Clever-1 could limit the replication capacity of cancer cells, increase antigen presentation, ignite an immune response, and allow current chemotherapy treatments to be more effective.
