Patent Describes Use of Self-Assembling Peptidomimetics to Create Barriers that Prevent Movement of Bodily Fluids and Contaminants, as well as Other Applications

FRAMINGHAM, MA -- (Marketwired) -- 02/02/17 -- Arch Therapeutics, Inc. (OTCQB: ARTH) ("Arch" or the "Company"), developer of novel liquid, gel and solid hemostatic and wound care devices, announced that the U.S. Patent and Trademark Office has issued a broad method-of-use patent for products that contain self-assembling peptidomimetics (U.S. Patent number 9,511,113). The patent is assigned to the Massachusetts Institute of Technology (MIT) and Versitech Limited and is licensed exclusively to Arch. Arch is developing products that contain self-assembling materials, such as the AC5™ family of devices, that may provide faster, safer and improved solutions for surgical, wound and interventional care. Arch anticipates that this patent will provide further value and opportunities for its pipeline.

The broad method-of-use claims cover techniques for preventing the loss or unwanted movement of body fluids through the application of products that contain peptidomimetics that self-assemble into barrier structures on tissue. Peptidomimetics, which are synthetic molecules made at least partially from amino acids that do not occur in nature, can mimic peptide structure and function, with potentially more desirable characteristics. Examples of procedures potentially supported by this intellectual property include the use of hemostatic agents to limit or stop bleeding, barrier structures that prevent contamination or infection, sealants to stop leaks, and applications in the wound care and tissue regeneration space.

Dr. Terrence W. Norchi, President and CEO of Arch Therapeutics, said, "We are committed to building and enhancing our portfolio of assets in order to add value to Arch and further protect our products in development and potential pipeline. This patent may offer insight into our future products opportunities."

Dr. Norchi continued, "In the meantime, we continue to make progress with our plans to submit both European and U.S. regulatory filings for AC5 devices, and there has been no new incremental request for information since we completed our clinical trial. We continue to work with our partners to finalize the manufacturing and quality information necessary to support our regulatory filings. We look forward to filing a CE Mark as soon as possible, and we are excited about our recently announced plans and opportunities regarding the U.S. 510(k) pathway."

The patent is expected to further enhance intellectual property protection around potential future products in development. It complements Arch's current intellectual property estate, which includes patents focused on self-assembling peptides made of amino acids that occur in nature and a patent covering peptidomimetic compositions-of-matter.

Arch has filed its own patent applications and, in addition, has worldwide exclusive rights to certain patents and patent applications assigned to MIT and Versitech Limited, the technology transfer company of the University of Hong Kong. The intellectual property estate either assigned to or exclusively licensed by Arch or its wholly owned subsidiary, Arch Biosurgery, Inc., includes 45 patents and pending applications in multiple jurisdictions, including seven issued patents in the U.S. 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 U.S., Israel, Europe, Japan, Canada, Australia, Hong Kong and China. Additional patent applications are pending in multiple jurisdictions.
