Faron Announces Topline MATINS Biomarker Analysis
STOCKHOLM, Dec. 9, 2021 /PRNewswire/ -- Faron Pharmaceuticals Ltd.
Topline Biomarker Analysis Shows Bexmarilimab Ignites Immune Response in Patient Population That Has Not Traditionally
Benefited from Current Immunotherapy Treatments
- Patients with low baseline levels of inflammatory cytokines in blood achieved significantly higher clinical benefit following treatment with bexmarilimab monotherapy
- Low inflammatory biomarker profile is likely to predict bexmarilimab monotherapy clinical benefit
- Ignition of immune response, as indicated by increased levels of inflammatory cytokines following treatment with bexmarilimab, suggests patients could become responsive to PD-1 blockade
Company announcement, December 9, 2021 at 02:00 AM (EDT) / 07:00 AM (GMT) / 09:00 AM (EET)
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 topline biomarker data from the Phase I/II MATINS (Macrophage Antibody to Inhibit Immune Suppression) trial of bexmarilimab. The initial biomarker data shows patients with low interferon gamma (IFNg) and tumor necrosis factor alpha (TNFa) levels experienced significantly higher clinical benefit (defined as partial response or stable disease) following treatment with bexmarilimab. The biomarker analysis included the first three cohorts of special interest from the trial: cutaneous melanoma, gastric cancer, and cholangiocarcinoma.
Among the 30 patients included in the analysis, all of whom were heavily pre-treated, and PD-1 blockade refractory/resistant, nine experienced clinical benefit and 21 did not following treatment with bexmarilimab monotherapy. At baseline, the nine patients who experienced clinical benefit had significantly lower serum IFNg (P = 0.03) and TNFa (P = 0.005) levels compared to patients that did not experience clinical benefit. Additionally, a more than 100% increase in IFNg levels was seen after the first cycle of bexmarilimab treatment among patients who experienced clinical benefit.
"The biomarker analysis shows that in patients receiving treatment with bexmarilimab, interferon gamma levels increased after the first dose. Interferon gamma is a marker for inflammation which suggests bexmarilimab may amplify an immune response." said Dr. Anna Minchom, Consultant Medical Oncologist at the Royal Marsden Hospital, Team Leader at the Institute of Cancer Research and MATINS investigator. "There is urgent clinical need to identify potential treatment options for patients who do not, currently, respond to existing immunotherapy drugs."
TNFa and IFNg are measured by a standard blood test. The ability to have these classical pro-inflammatory cytokines measured as part of a patient's routine clinical care could expedite treatment decisions improving patient care, which today requires costly biopsies and pathology tests.
"The initial biomarker analysis is exciting as it helps us better understand which patients are most likely to respond to treatment with bexmarilimab monotherapy," said Dr. Markku Jalkanen, Chief Executive Officer of Faron. "The data also demonstrates that bexmarilimab is igniting an immune response, turning a cold tumor hot, in certain heavily pre-treated patients with checkpoint inhibitor resistant disease. This means bexmarilimab may serve as a catalyst for the immune system allowing initially checkpoint inhibitor resistant patients to become responsive to PD-1 blockade."
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. Overall survival data at six months was presented at the European Society for Medical Oncology (ESMO) 2021 Congress that showed that 83% of patients who experienced clinical benefit following treatment with bexmarilimab were alive at six months compared to 29% of patients who did not experience clinical benefit. Median survival for patients who experienced clinical benefit had not yet been reached. Treatment with bexmarilimab was well tolerated with only 7% of treatment related adverse events (TRAEs) reported as grade three or four and 0% reported as grade five. Additionally, none of the TEAEs resulted in a decrease or modification of dosing. The most common TRAEs were fatigue, anemia, abdominal pain and decreased appetite.
The company will complete a full evaluation of the biomarker data and share the detailed results at a future medical meeting.

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.
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.
