U.S. Patent Addresses Use of the Self-Assembling Peptide Barrier Technology to Treat Disorders Involving Leaky Tight Junctions and Extracellular Matrix

FRAMINGHAM, MA -- (Marketwired) -- 04/25/16 -- 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, received a notice of allowance from the U.S. Patent Office for a broad method-of-use patent that covers systemically administering the Company's self-assembling technology for treating damaged extracellular matrix and leaky tight junctions.

Many disorders are associated with leakage around blood vessels and within the tight junctions between cells. Such leakage can lead to fluid invading the tissues, causing a loss in blood pressure, organ dysfunction or failure, and death. Some examples include inflammatory bowel disease, sepsis and ischemic stroke.

Dr. Terrence W. Norchi, President and CEO of Arch Therapeutics, said, "This important patent lends additional support to Arch's planned products. It is another example of Arch's inventiveness in exploring better ways to address a range of areas of unmet or poorly met medical needs with our self-assembling peptide technology."

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, Japan, Canada, Israel, Australia, Hong Kong and China. Additional patent applications are pending in multiple jurisdictions.
