Argen-X Granted Broad Patent Covering its Simple Antibody™ Platform
arGEN-X, a biopharmaceutical company focused on the discovery and development of human monoclonal antibodies using its proprietary SIMPLE Antibody™ platform, announces that it has been granted the first patent covering the platform. The patent GB2461546B, has been granted by the UK Patent and Trademark Office (UKPTO).
The broad granted patent covers arGEN-X’s SIMPLE Antibody™ technology, which yields gold standard human therapeutic antibodies with an unmatched functional diversity. It also covers arGEN-X’s antibody products as well as methods of generating them. arGEN-X is prosecuting additional patent applications globally, which when granted will provide the company with an IP position in the human antibody space.
arGEN-X’ SIMPLE Antibody™ platform utilizes the active immunization of outbred Camelids with a target antigen to deliver highly diverse antibodies whose variable regions are nearly identical to those of human antibodies. arGEN-X then uses these to produce variable antibody regions with 96-99% human sequence homology via minimal germlining (humanization). This is achieved without any loss in affinity and potency in just a matter of weeks. These variable domains are then combined with human constant domains to generate full size, fully human therapeutic antibodies.
A further key attraction of the SIMPLE Antibody™ platform is its ability to generate diverse panels of ultra-potent antibodies to a broad range of targets, including intractable and conserved targets. These antibody panels blanket the target of interest providing pharma researchers with more choice in the drug discovery stage. This allows them to use more stringent lead selection criteria, increasing the probability of successful therapeutic antibody development.
arGEN-X has already demonstrated that human antibodies generated using its SIMPLE Antibody™ platform routinely exhibit gold standard potencies and affinities, without the need for additional engineering. These properties combined with their excellent manufacturability, make them an ideal starting point for a therapeutic antibody development program.
Prof. Hans de Haard, CSO of arGEN-X commenting on the announcement said: “The UKPTO’s decision to grant the first patent for our SIMPLE Antibody™ platform is a major value-enhancing milestone in arGEN-X’ corporate development. It is also a key step in our goal to achieve a broad and unencumbered global IP position for our platform which will give us a highly competitive position in the human antibody space”.
Prof. Haard continued, “As we work with our SIMPLE Antibody™ platform, we are increasingly convinced that it will transform the discovery and development of human therapeutic antibodies. This is due to its ability to rapidly produce incredibly diverse panels of ultra potent antibodies that address a broad range of both intractable and conserved targets. These unique properties are already generating considerable interest amongst potential partners who are looking to access a platform around which they can build broadly based therapeutic antibody discovery and development programs.”
arGEN-X is currently using the power of the SIMPLE Antibody™ platform to build its business by making this technology and know-how available to biopharmaceutical companies through selective strategic partnerships and by developing its own portfolio of exciting therapeutic antibody candidates.
According to arGEN-X, the power of the SIMPLE Antibody™ platform is enabling the Company to build its own pipeline. arGEN-X’ lead product, ARGX-109, a fully human mAb targeting autoimmune, inflammation and oncology indications, has already entered preclinical development in less than 12 months from start of the discovery process. ARGX-109, which targets the cytokine IL-6, has already shown very high potencies in a range of in vivo studies. arGEN-X currently has a further three therapeutic antibody candidates in its own development pipeline.
