Ex Vivo Data Presented at EHA2022 Congress Suggest Critical Role for Clever-1 in
Hematological Cancer Outcome and Drug Resistance
· Clever-1 is expressed in patient bone marrow blasts and monocytes in acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), with the highest levels observed in M4/M5 subtypes with poor outcome
· Blocking Clever-1 with bexmarilimab in these patients induced immune activation as observed through increased antigen presenting molecule, human leucocyte antigen DR (HLA-DR) expression and declined PD-1 expression
· The combination of azacytidine with bexmarilimab augmented HLA-DR induction and overcame the HLA-DR suppressing effect of the bcl-2 inhibitor venetoclax
Press release, May 12, 2022 at 17:50 PM (EEST) / 15:50 PM (BST) / 10:50 AM (EDT)
TURKU, FINLAND / BOSTON, MA - Faron Pharmaceuticals Ltd (AIM: FARN, First North: FARON), a clinical stage biopharmaceutical company focused on building the future of immunotherapy by harnessing the power of the immune system to tackle cancer and inflammation, today announces that preclinical data to support the Company's upcoming clinical trials investigating the potential of bexmarilimab in combination with standard of care (SoC) in hematologic cancers will be presented at the European Hematology Association's hybrid EHA2022 Congress in Vienna, Austria, from June 9-12, 2022. These data (Abstract ID: EHA-3535) will be presented on Friday, June 10, 2022 in a session that begins at 16:30 CEST. The abstract can be found here: EX VIVO IMMUNE ACTIVATION WITH THE MACROPHAGE-TARGETING.... EHA Library. Aakko S. Jun 10 2022; 357243 (ehaweb.org)
Faron's wholly-owned novel precision cancer immunotherapy, bexmarilimab, targets Clever-1, a receptor known to be expressed on immunosuppressive tumor associated macrophages which make up nearly 50% of the tumor mass and limit the efficacy of currently approved cancer immunotherapies, including anti PD-1/L1. Faron is investigating the potential of this novel immunotherapy in combination with SoC in patients with relapsed acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), or chronic myelomonocytic leukemia (CML), three hematologic cancers for which there are few treatment options.
The data being presented at EHA2022 profiles Clever-1 expression in blood cancer and tests bexmarilimab's growth inhibitory and immunomodulatory potential in preclinical models, as a monotherapy and in combination with azaciditine and/or venetoclax, two standard of care treatments used as in AML, MDS and CML. Results confirmed that Clever-1 is expressed in patient-derived monocytes and blasts. Ex vivo treatment with bexmarilimab, alone or in combination with azaciditine and/or venetoclax, demonstrated increased expression of the antigen presenting molecule, human leucocyte antigen DR (HLA-DR). Enhanced antigen presentation allows the immune system to better identify and kill cancer cells
Furthermore, natural killer (NK) cells and CD8+ T cells showed decreased expression of PD-1 and an increase of activation markers - important predictive biomarkers for overcoming resistance to existing immunotherapies. These results help confirm bexmarilimab's potential in hematologic malignancies.
"These results reinforce the strong scientific rationale behind our focus on Clever-1 and the potential of bexmarilimab, either alone or in combination with standard of care, to treat blood cancers," said Marie-Louise Fjällskog, M.D., Ph.D., Chief Medical Officer of Faron. "High Clever-1 expression is associated with poor survival in certain blood cancer patients and bexmarilimab provides a novel treatment approach for these patients, downregulating Clever-1 expression and igniting an effective immune response. We look forward to the imminent start of our hematology cancer clinical trial program to further explore these promising findings."

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. In mouse models, bexmarilimab has successfully blocked or silenced Clever-1, activating antigen presentation and promoting interferon gamma secretion by leukocytes. Additional pre-clinical studies have proven that Clever-1, encoded by the Stabilin-1 or STAB-1 gene, is a major source of T cell exhaustion and involved in cancer growth and spread. Observations from clinical studies to date indicate that Clever-1 has the capacity to control T cell activation directly, suggesting that the inactivation of Clever-1 as an immune suppressive molecule could be more broadly applicable and more important than previously thought. As an immuno-oncology therapy, bexmarilimab has potential as a single-agent therapy or in combination with other standard treatments including immune checkpoint molecules. Beyond immuno-oncology, it offers potential in infectious diseases, vaccine development and more.
About Faron Pharmaceuticals Ltd
Faron (AIM: FARN, First North: FARON) is a clinical stage biopharmaceutical company developing novel treatments for medical conditions with significant unmet needs caused by dysfunction of our immune system. The Company currently has a pipeline based on the receptors involved in regulation of immune response in oncology, organ damage and bone marrow regeneration. Bexmarilimab, a novel anti-Clever-1 humanized antibody, is its investigative precision immunotherapy with the potential to provide permanent immune stimulation for difficult-to-treat cancers through targeting myeloid function. Currently in Phase I/II clinical development as a potential therapy for patients with untreatable solid tumors, bexmarilimab has potential as a single-agent therapy or in combination with other standard treatments including immune checkpoint molecules. Traumakine is an investigational intravenous (IV) interferon beta-1a therapy for the treatment of acute respiratory distress syndrome (ARDS) and other ischemic or hyperinflammatory conditions. Traumakine is currently being evaluated in global trials as a potential treatment for hospitalized patients with COVID-19 and with the 59th Medical Wing of the US Air Force and the US Department of Defense for the prevention of multiple organ dysfunction syndrome (MODS) after ischemia-reperfusion injury caused by a major trauma.
