Arch Therapeutics Announces Favorable Preclinical Data from an
Independent Study of AC5 Surgical Hemostatic Device™ versus a Popular Fibrin Sealant

Data Shows Faster Time to Control Bleeding for AC5 versus Competitor

FRAMINGHAM, MA – April 14, 2015 -- Arch Therapeutics, Inc. (OTCQB: ARTH) ("Arch" or the "Company"), developer of the AC5 Surgical Hemostatic Device™ (AC5^TM) for use in controlling bleeding and fluid loss in order to provide faster and safer surgical and interventional care, announced that an independent third party has obtained favorable data from a preclinical animal study that compared the hemostatic activity of AC5 with a popular and commercially available branded fibrin sealant that is indicated for use in controlling bleeding.

In this study, full thickness penetrating wounds were surgically created in rat livers, which are highly vascularized parenchymal organs, and then either AC5^TM or the fibrin sealant was applied in order to stop the bleeding. The time to hemostasis (TTH), which is the time required to stop bleeding, was measured.

The average TTH after application of AC5 was significantly less than 30 seconds. The average TTH for the fibrin sealant was approximately 50% longer.

AC5 was maintained at room temperature without requiring cold storage, whereas the fibrin sealant was maintained frozen during storage, in accordance with its prescribing directions. This is a common constraint of many commercial hemostatic agents that are derived from blood-products. Such products also require a multi-step preparation procedure prior to use.

AC5 contains a self-assembling peptide comprising naturally occurring amino acids that are not sourced from humans or animals, whereas the fibrin sealant is made from pooled human plasma (blood product). Fibrin sealants and other products that are sourced from human or animal blood products can contain infectious agents, such as viruses and potentially the Creutzfeldt-Jakob disease (CJD) agent, which potentially can be transferred to a patient.

The study group intends to submit the data for publication, at which time additional details would be made publicly available. This animal trial was conducted as part of an ongoing series of studies comparing AC5 with currently marketed hemostatic products that are used in surgical procedures.

Terrence W. Norchi, MD, President and CEO of Arch Therapeutics, said, “AC5 has again shown promising results. Data from the preclinical studies conducted to date indicates that AC5 has favorable efficacy when compared to a number of other popular hemostatic agents. Furthermore, data to date continues to support that it is both easy to use and non-toxic. Compared to the products on the market that are sourced from humans or animals, AC5 is instead manufactured synthetically from amino acids that are not derived from humans or other animals, and therefore, would not be expected to carry that particular risk factor.”

The research was led by Rudolf Urbanics, MD, PhD, and Domokos Csukas, DVM at Semmelweis University Faculty of Medicine in Budapest, Hungary within the Department of Surgical Research and Techniques. The research was sponsored by Arch. Also part of the research team was Dr. Rutledge Ellis-Behnke, Director of the Nanomedicine Translational Think Tank in the Department of Ophthalmology at the Medical Faculty Mannheim of the University of Heidelberg in Germany. Dr. Ellis-Behnke is also affiliated with three U.S. academic institutions, and he is an advisor to and co-founder of Arch.
