Bexmarilimab granted key US patent

Company announcement, 14 June 2021 at 9.00 AM (EEST)

TURKU – FINLAND – Faron Pharmaceuticals Oy (AIM: FARN, First North: FARON), the clinical stage biopharmaceutical company, today announces that the United States Patent and Trademark Office has granted a new US Patent, No. 11,046,761, with claims protecting the composition of matter of bexmarilimab. The patent will be issued on 29 June, 2021.

Faron's wholly-owned novel precision cancer immunotherapy drug candidate, bexmarilimab, targets the Clever-1 receptor, known to be expressed on immunosuppressive macrophages in the tumour microenvironment and circulating in soluble form, and which is capable of directly inhibiting T-cell activation. The reprogramming of these Clever-1 positive macrophages by bexmarilimab, from an immunosuppressive state to an immune-stimulating one, is believed to be a key immune defence against tumour growth and spread.

Bexmarilimab is currently being investigated in the ongoing Phase I/II MATINS trial as a potential monotherapy in patients with solid tumours who have exhausted all treatment options. Latest data from the trial have shown strong initial safety and tolerability, and promising anti-tumour activity in several refractory metastatic solid tumours – cutaneous melanoma, gastric cancer and cholangiocarcinoma.

The US composition of matter patent covers bexmarilimab’s binding sequences and Clever-1’s corresponding epitope – specific elements of the antibody-antigen binding site. The expiry date, not including any potential extensions, is expected to be 2037.

The same patent has been granted in Japan and applications are under review in other key territories including Europe and China.

Dr. Markku Jalkanen, Faron's CEO, said: “We are extremely pleased to receive this key patent approval which grants us market exclusivity up to 2037. This patent protection applies specifically to the binding process between bexmarilimab and its target, the Clever-1 receptor found on the surface of tumour associated macrophages in the tumour microenvironment. This novel binding is key to the conversion of these highly immunosuppressive macrophages to immune-stimulating ones that can target difficult-to-treat cancers, and key to the removal of soluble Clever-1 from remote locations, where it can prevent activation of immune cells. The patent is a welcome addition to our existing global IP portfolio for targeting Clever-1 and further strengthens the long-term potential of this next-generation macrophage reprogramming immunotherapy.”

About Faron Pharmaceuticals Ltd

Faron (AIM: FARN, First North: FARON) is a clinical stage biopharmaceutical company developing novel treatments for medical conditions with significant unmet needs caused by dysfunction of our immune system. The Company currently has a pipeline based on the receptors involved in regulation of immune response in oncology, organ damage and bone marrow regeneration. Bexmarilimab, a novel anti-Clever-1 humanised antibody, is its investigative precision immunotherapy with the potential to provide permanent immune stimulation for difficult-to-treat cancers through targeting myeloid function. Currently in Phase I/II clinical development as a potential therapy for patients with untreatable solid tumours, bexmarilimab has potential as a single-agent therapy or in combination with other standard treatments including immune checkpoint molecules. Traumakine is an investigational intravenous (IV) interferon beta-1a therapy for the treatment of acute respiratory distress syndrome (ARDS) and other ischemic or hyperinflammatory conditions. Traumakine is currently being evaluated in global trials as a potential treatment for hospitalised patients with COVID-19 and with the 59th Medical Wing of the US Air Force and the US Department of Defense for the prevention of multiple organ dysfunction syndrome (MODS) after ischemia-reperfusion injury caused by a major trauma.  Faron is based in Turku, Finland.
