New biomarker data from BEXMAB study at EHA2023

Faron Announces New Biomarker Data from Phase I/II BEXMAB Study at EHA2023 Hybrid Congress
- Bexmarilimab mode of action in AML/MDS supported with durable Clever-1 target engagement in bone marrow, with increases observed in T and NK cells and antigen presentation
- Clinical activity across indications, with objective responses in 5 of 10 patients
- Dose escalation ongoing, with initiation in 2H 2023 of Phase II in relapsed/refractory AML and MDS after failure on hypomethylating agents
The data will feature in a poster presentation at the European Hematology Association (EHA) 2023 Hybrid Congress on June 9, 2023.
In BEXMAB patients, a high Clever-1 expression in leukemic blasts is associated with lower levels of antigen presentation. The proposed mode of action of bexmarilimab in AML/MDS is now supported by the biomarker data, which suggests durable Clever-1 target engagement in the bone marrow tumor microenvironment with increases observed in key cell types limiting cancer growth and spread, namely T and NK cells (up to 2-3-fold). In addition, bexmarilimab treatment increased HLA-DR expression by leukemic blasts, indicating improved immune recognition and eradication of the malignant cells.
The poster also updates preliminary efficacy data, previously communicated by the Company in January and April 2023, showing objective responses in 5 out of 10 patients across the first and second dose cohorts of the study (1 or 3mg/kg bexmarilimab + azacitidine), as observed by a reduction in bone marrow blasts, leading to complete and partial remissions. The initial data also shows that bexmarilimab treatment is well-tolerated without adding toxicity to standard azacitidine therapy.
"The BEXMAB study continues to generate data that are an excellent indication of the therapeutic potential of bexmarilimab to change the treatment paradigm for patients with hematological malignancies," said Marie-Louise Fjällskog, M.D., Ph.D., Chief Medical Officer of Faron Pharmaceuticals. "We are encouraged by the results and look forward to progressing the BEXMAB program."

About Bexmarilimab
Bexmarilimab, a humanized IgG4 monoclonal antibody, binds common lymphatic endothelial and vascular endothelial receptor-1 (Clever-1), a novel macrophage checkpoint. Clever-1 alters the function of macrophages, a type of white blood cell that surrounds and kills micro-organisms. High Clever-1 expression is associated with therapeutic resistance and poor outcomes. Ex vivo treatment of AML bone marrow cells with bexmarilimab alone or in combination with azacitidine/venetoclax increases antigen presentation, induces secretion of proinflammatory cytokines (signaling proteins that help control inflammation in the body) and increases activation of white blood cells called T cells, which allows cancer to be targeted and eliminated.
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 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 (azacytidine) 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.
About Faron Pharmaceuticals Oy
Faron Pharmaceuticals Oy (AIM: FARN, First North: FARON), together with its subsidiaries, is a clinical stage biopharmaceutical group focused on building the future of immunotherapy by harnessing the power of the immune system to tackle cancer. Bexmarilimab, a novel anti-Clever-1 humanized antibody, is its investigational immunotherapy with the potential to remove immunosuppression of cancers through targeting 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 including immune checkpoint molecules, and as a monotherapy for untreatable solid tumors.
