Presentation of Biomarker Data at AACR - Mar 09, 2022

Faron Announces Upcoming Presentation of Biomarker Analysis from Patients in MATINS Trial at AACR Annual Meeting 2022

  • Analysis tested performance of baseline cytokine serum IFNy and TNFa levels to identify patients that experienced disease control following bexmarilimab treatment compared to those that did not
  • Patients with low baseline IFNy and TNFa levels found to experience significantly higher clinical benefit following bexmarilimab treatment
  • Bexmarilimab's unique mode of action could serve as a catalyst for the immune system allowing initially checkpoint inhibitor resistant patients to become responsive to PD-1 blockade

TURKU, Finland and BOSTON, March 9, 2022 /PRNewswire/ -- 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 an analysis of biomarker data from patients treated with bexmarilimab as part of the ongoing phase I/II MATINS (Macrophage Antibody to Inhibit Immune Suppression) trial, will be presented at the upcoming American Association for Cancer Research (AACR) Annual Meeting being held in New Orleans, US, from April 8 - 13, 2022. These data (Abstract #2767) will be featured in the "Biomarkers Predictive of Therapeutic Benefit" session on Tuesday April 12, 2022 from 9:00 AM - 12:30 PM.

Top line data from the biomarker analysis, which was announced by the Company in December 2021, showed that patients with low baseline levels of serum interferon gamma (IFNy) and tumor necrosis factor alpha (TNFa) were more likely to experience clinical benefit following treatment with bexmarilimab, Faron's wholly-owned investigational precision immunotherapy asset. Data scheduled for presentation at AACR includes more detailed analysis of 30 patients across three tumor types (advanced gastric cancer, cutaneous melanoma and cholangiocarcinoma) showing:

  • Mean levels of IFNy were 5.11 pg/ml (SD +/- 4.99 pg/ml) in patients who experienced a clinical benefit versus 13.07 pg/ml
    (SD, +/- 13.26) in patients who did not experience a clinical benefit with bexmarilimab
  • Mean levels of TNFa were 0.96 pg/ml (SD, +/- 0.74 pg/ml) in patients who experienced a clinical benefit versus 2.37 pg/ml
    (SD, +/- 1.43 pg/ml) in patients who did not experience a clinical benefit with bexmarilimab

The conclusion from the analysis is that, when used together, IFNy and TNFa are highly predictive of response to bexmarilimab (P < 0.0001), and patients with low IFNy and TNFa levels experienced significantly higher clinical benefit following treatment with bexmarilimab. Patients with low levels of pro-inflammatory cytokines experiencing higher clinical benefit is opposite to what is usually seen with currently approved checkpoint inhibitors and other T cell activating agents.

"Understanding which patients are most likely to benefit from immunotherapy treatment is key to tackling cancer," said Petri Bono, MD, PhD., Chief Medical Officer, Terveystalo Finland and Principal Investigator of the MATINS trial. "This biomarker analysis shows that IFNy and TNFa, which can both be measured by a standard blood test, perform well in identifying patients likely to respond to bexmarilimab and could offer the potential to personalize a patient's therapy and, ultimately, improve their outcome. This is especially important in earlier treatment line settings and with combination regimens."

"This analysis continues to strengthen our understanding of what happens in the tumor microenvironment when patients are treated with bexmarilimab," said Dr. Markku Jalkanen, Chief Executive Officer of Faron. "It provides a strong biological rational to guide our ambitious development program exploring bexmarilimab's potential as a monotherapy and in combination with other therapies, only increasing our confidence of the potential impact this novel macrophage-targeting immunotherapy could have on cancer care. Bexmarilimab's ability to ignite immune reaction could become a significant new tool to increase the stagnated response levels of the currently available and widely used anti-PD-(L)1 treatments."

The ongoing open label Phase I/II MATINS clinical trial is investigating the safety and efficacy of bexmarilimab, Faron's wholly-owned novel precision cancer immunotherapy targeting Clever-1, a receptor known to be expressed on immunosuppressive macrophages in the tumor microenvironment. In the MATINS trial, bexmarilimab is being investigated as a potential monotherapy in patients with solid tumors who have exhausted all other treatment options. Landmark overall survival (OS) data presented at the Company's R&D Day in February from patients in Part I/II of the trial who received three courses of treatment and had their scheduled tumor imaging at cycle four (n=92) estimated that 70% of disease control rate (DCR = partial response + stable disease rate) patients were alive at nine months after the landmark (that is, approximately 11 months from initiation of treatment) compared to 26% of non-DCR patients. The most DCR among Part II cohorts was observed in cutaneous melanoma (30%), gastric cancer (30%), cholangiocarcinoma (30%), hepatocellular carcinoma (40%) and breast cancer (40%) patients. Treatment with bexmarilimab continues to be well tolerated with no new safety signals reported and no treatment related adverse events resulting in a decrease or modification of dosing.

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. 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 MATINS

The MATINS (Macrophage Antibody To INhibit immune Suppression) study is a first-in-human open label phase I/II clinical trial investigating the tolerability, safety and efficacy of bexmarilimab in ten different hard-to-treat metastatic or inoperable solid tumour cohorts - cholangiocarcinoma, colorectal cancer, cutaneous melanoma, ER+ breast cancer, gastric cancer, hepatocellular carcinoma, ovarian cancer, uveal melanoma, pancreatic cancer and anaplastic thyroid carcinoma - which are all known to host a significant number of Clever-1 positive tumour-associated macrophages (TAMs). The completed Part I of the trial dealt with tolerability, safety and dose escalation. The ongoing Part II is focused on identifying patients who show an increased number of Clever-1 positive TAMs and exploring safety and efficacy. Part III will be focused on assessing efficacy. Data from MATINS have shown that bexmarilimab has the potential to be the first macrophage immune checkpoint therapy. To date, the investigational therapy has been shown to be safe and well-tolerated, making it a low-risk candidate for combination with existing cancer therapies, and has demonstrated early signs of clinical benefit in patients who have exhausted all other treatment options.
