      Second dose level in doublet well-tolerated and third cohort open for enrolment

      First dose level in triplet well tolerated and second cohort open for enrollment

      Plans to initiate the study's Phase II in H2 2023

Company announcement, April 17, 2023

Inside information

TURKU, FINLAND / BOSTON, MA - Faron Pharmaceuticals Oy (AIM: FARN, First North: FARON), a clinical stage biopharmaceutical company focused on tackling cancers via novel immunotherapies, today announces additional positive data from the Company's Phase I/II BEXMAB study. BEXMAB is investigating bexmarilimab, Faron's wholly owned immunotherapy asset, in combination with standard of care (SoC) in relapsed/refractory acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS).

The responses from these patients are further defined as:

      In the second doublet cohort (3mg/kg + azacytidine), two patients have objective responses thus far, including one complete response with incomplete blood count recovery (CRi) and one patient with hematological improvement in platelets (HI-P). There are two patients with SD, of which one has > 50% reduction in bone marrow blasts, and one patient with progressive disease.

      The first doublet cohort (1mg/kg + azacytidine) has seen a complete response with incomplete hematological recovery (CRi) in a patient with relapsed/refractory AML. The patient is still responding after 10 months. Another patient with MDS that experienced CR is still in remission after 9 months. An additional patient that achieved a partial response has undergone a possibly curative allogenic stem cell transplantation.

      No bexmarilimab-related Grade 3 or higher adverse events (AEs) or serious adverse events (SAEs) observed in the second dosing cohort and enrolment into the third cohort (6mg/kg) ongoing.

      The first triplet cohort (1mg/kg + azacytidine + venetoclax) was well-tolerated and the second cohort (3mg/kg + azacytidine + venetoclax) has opened for enrollment.

      Additional efficacy read-outs for all cohorts expected in the upcoming months.

      On a potential path to a Biologics License Application (BLA) submission, the Company plans to seek FDA advice during Q3 2023.

"We are extremely encouraged by the continued efficacy of bexmarilimab and the long duration of the responses seen so far," said Chief Medical Officer Marie-Louise Fjällskog. Dr. Fjällskog noted the success of the MDS patient who did not respond to previous azacytidine therapy, but with the addition of bexmarilimab, the patient is undergoing potentially curative transplantation.

The primary objective of the BEXMAB study (ClinicalTrials.gov: NCT05428969) is to determine the safety and tolerability of bexmarilimab in combination with SoC (azacytidine and venetoclax) treatment and to identify the recommended Phase II dose. Secondary objectives include characterizing preliminary efficacy as well as bexmarilimab's pharmacokinetic profile in combination with SoC treatment and assessing its immunogenicity.

In January 2023, the Company announced objective responses in 3 out of 5 patients dosed in the first doublet cohort of the BEXMAB study. The Company also announced enrollment updates for the study's cohorts, and that it had opened the first triplet cohort with bexmarilimab, azacytidine and venetoclax in newly diagnosed AML patients who are unable to tolerate chemotherapy.

"The latest data are a powerful indication of the therapeutic potential for bexmarilimab in hematological malignancies," said CEO Dr. Markku Jalkanen.

About Bexmarilimab

Bexmarilimab is Faron's wholly owned, investigational immunotherapy with the potential to provide immune stimulation for treatment-resistant cancers through targeting myeloid cell function. A novel anti-CLEVER-1 humanized antibody, bexmarilimab targets CLEVER-1 positive (Common Lymphatic Endothelial and Vascular Endothelial Receptor 1) tumor-associated macrophages (TAMs) in the tumor microenvironment, converting highly immunosuppressive M2 macrophages to immune-stimulating M1 macrophages. As an immuno-oncology therapy, bexmarilimab has therapeutic potential in combination with other standard treatments including immune checkpoint molecules in both solid tumors and hematologic malignancies.

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 and solid cancers in combination with other standard treatments including immune checkpoint molecules. Faron is headquartered in Turku, Finland. Further information is available at www.faron.com.
