Inside information: Faron Presents Phase 1 Data from BEXMAB in Myeloid Malignancies Trial at the 65th American Society of Hematology (ASH) Annual Meeting

-      Significant overall Response Rate (ORR) achieved in both HR-MDS (5/5) and HMA-failed MDS (5/5) patients

Company Announcement, Inside Information

TURKU, Finland / BOSTON, Massachusetts - December 11, 2023 - Faron Pharmaceuticals Ltd. (AIM: FARN, First North: FARON), a clinical-stage biopharmaceutical company pioneering macrophage reprogramming for effective anticancer immunotherapies, today announced very positive Phase 1 data from the ongoing BEXMAB study in myeloid malignancies, being presented at the 65th American Society of Hematology (ASH) Annual Meeting & Exposition taking place until tomorrow, December 12, 2023, in San Diego, California, and virtually.

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 standard of care in patients with aggressive myeloid leukemias.

"The BEXMAB results continue to improve over time showing remarkable overall response rate in both higher-risk frontline as well as hypomethylating agent (HMA)-failed myelodysplastic syndrome (MDS) patients," said Dr. Markku Jalkanen, Chief Executive Officer of Faron. "The combination is well-tolerated and generates strong and durable leukemic blast eradication and immune responses. This solidifies bexmarilimab's unique and leading mechanism of action in the field of myeloid cell re-programming. With this compelling evidence we are well positioned to advance to the Phase 2 part of the BEXMAB study and actively pursue further regulatory interactions to navigate and refine the pivotal pathway for BLA filing".

Dr. Naval Daver, MD, Professor of Leukemia at The University of Texas MD Anderson Cancer Center and site Principal Investigator of the BEXMAB trial commented: "Addressing MDS poses a considerable therapeutic challenge given the limited efficacy of the current standard of care resulting in relatively low response rate and poor overall survival, especially in TP53 mutated and HMA-failed MDS patient populations. The data presented at ASH are promising, demonstrating a higher ORR and prolonged response duration in this trial compared to published historical benchmarks. These findings underscore the future potential of this combination in advancing the treatment of higher-risk and HMA-failed MDS."

Poster highlights include:

·    Significant overall response rate observed in both previously HMA-failed (5 out of 5) and higher-risk MDS patient (5 out of 5) populations

·    Observed responses were primarily deep and durable with 7/10 MDS patients achieving CR/mCR, and two demonstrating PR, out of which one moved on to receive a stem cell transplantation and one hematological improvement without remission (HI-P)

·    The majority of higher-risk MDS patients were also TP53 mutated, typically associated with poor responsiveness to standard therapy, however all of them achieved CR/mCR upon receiving the treatment

·    Clinical activity with 13/28 (48%) objective responses observed across all the indications, including r/r AML, and dose levels tested

·    The combination of bexmarilimab and azacitidine remains well tolerated with immune-related adverse events observed at higher dose levels

·    Clever-1 target engagement was confirmed in the bone marrow of treated patients together with an increased antigen presentation capacity and increased numbers of CD8 T and NK cells in patients

About BEXMAB

The BEXMAB study is an open-label 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. 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 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 treatments and as a monotherapy in last line solid cancers.
