U.S. Patent Governs Use of Self-Assembling Peptides to Prevent Movement of Bodily Fluids in Hemostasis, Sealant and Other Barrier Applications

FRAMINGHAM, MA -- (Marketwired) -- 04/05/16 -- 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 today that a notice of allowance from the U.S. Patent Office has been received on a broad composition-of-matter patent that 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 Arch's present and proposed products, which contain peptides that self-assemble into barrier structures on tissue that inhibit or prevent the passage of bodily fluids. Examples of potential products supported by this intellectual property include hemostatic agents to stop bleeding and sealants to stop leaks.

Dr. Terrence W. Norchi, President and CEO of Arch Therapeutics, said, "This patent further validates the innovative nature of our self-assembling technology and our approach to addressing important areas of unmet need. We remain focused on developing products that will make a difference in patients' lives. Our first product in development is AC5, which, based on preclinical data to date, has been shown to stop bleeding when it is applied directly to a wound. AC5 is a clear liquid product that we believe should provide a novel, safe, user-friendly approach to bleeding cessation during surgery or after trauma. We eagerly await the results of our first human trial in Europe and plan to file a CE Mark this summer."

Arch has filed its own patent applications and, in addition, has 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. 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, Japan, Canada, Australia, Hong Kong and China. Additional patent applications are pending in multiple jurisdictions.
