U.S. Patent Addresses Self-Assembling Peptidomimetics That Form Barrier Structures on Tissue and Inhibit or Prevent the Passage of Bodily Fluids and Contaminants
FRAMINGHAM, MA — ARTH, (Marketwired) — 05/16/16 — Arch Therapeutics, Inc. (OTCQB: ARTH) (“Arch” or the “Company”), developer of the AC5 Surgical Hemostatic Device™ (AC5™) for use in controlling bleeding and fluid loss in order to provide faster and safer surgical and interventional care, announced that the U.S. Patent Office has issued a composition of matter patent, which is assigned to the Massachusetts Institute of Technology (MIT) and Versitech Limited, and which is exclusively licensed worldwide to Arch.
The broad composition claims of the patent cover products that contain non-classical peptide molecules, called peptidomimetics, which self-assemble into barrier structures on tissue that inhibit or prevent the passage of bodily fluids. The peptidomimetic molecules mimic peptide structure, have general features analogous to a parent peptide, and can have properties that are advantageous when compared to the otherwise similar peptides that they mimic. Examples of potential products covered by this patent include hemostatic agents to stop bleeding, and self-assembled barrier structures that prevent contamination and stop leaks.
Dr. Terrence W. Norchi, President and CEO of Arch Therapeutics, said, “This patent covers self-assembling non-classical peptide products, which are separate from the classical self-assembling peptides we are known to be developing, and which may unlock novel features of potential future products. In the meantime, we continue to guide our first product in development, AC5, along the pathway toward regulatory approval, and we look forward to the conclusion of our first human trial in Europe.”
Arch has filed its own patent applications and, in addition, has licensed worldwide exclusive rights to certain patents and patent applications assigned jointly to MIT and Versitech Limited, the technology transfer company of the University of Hong Kong, and worldwide non-exclusive rights to another portfolio of patents assigned jointly to MIT and Versitech Limited. The applications and rights cover self-assembling compositions and methods of making and using such compositions for medical applications including stopping bleeding; preventing the movement of bodily fluids, contaminants, etc., within or on the human body; preventing adhesions; treatment of leaky or damaged tight junctions; and reinforcement of weak or damaged vessels, such as aneurysms, with patents covering this technology in the United States, Europe, Israel, Japan, Canada, Australia, Hong Kong and China. Additional patent applications are pending in multiple jurisdictions.
