Arch Therapeutics Announces Positive Preclinical Data From An Independent Study Of AC5 Surgical Hemostatic Device™

WELLESLEY, MA--(Marketwired - September 08, 2014) - Arch Therapeutics, Inc. (OTCQB: ARTH) ("Arch" or the "Company"), developer of the AC5 Surgical Hemostatic Device™, announced that an independent third-party research group has obtained positive data from a preclinical study assessing the use of AC5™ in animals receiving an anticoagulant medication (i.e. blood thinner). These results were consistent with the results obtained from a recently completed Arch study that showed that AC5 quickly stopped bleeding from surgical wounds created in the livers of rats that had been treated with a clinically relevant dose of the drug heparin.

Dr. Rutledge Ellis-Behnke, the inventor who discovered the hemostatic properties of self-assembling peptides and one of the study investigators, has previously demonstrated that a synthetic self-assembling peptide could achieve hemostasis in less than 30 seconds in a range of tissues in animal experiments. However, the published literature assessing the use of self-assembling peptides has not until now adequately addressed the potential for hemostasis in the presence of anticoagulant therapy in vivo. The results of this new study support that AC5 can achieve rapid hemostasis in living animals that have undergone anticoagulant treatment with heparin. The average time to hemostasis of the anticoagulated animals was comparable to that of the animals that were not anticoagulated, with the difference between the groups being less than one second.

The research, which was sponsored by Arch Therapeutics, was performed at Semmelweis University Faculty of Medicine in Budapest, Hungary within the Department of Surgical Research and Techniques. The study team also included Rudolf Urbanics, MD, PhD, and Domokos Csukas, DVM. Dr. Urbanics is Head of the in vivo laboratory of SeroScience Ltd and of the Nanomedicine Research and Education Center at Semmelweis University, both located in Budapest, Hungary. Dr. Csukas is a veterinary doctor and Assistant Lecturer in the Department of Surgical Research and Techniques at the Faculty of Medicine of Semmelweis University in Budapest, Hungary, where he is also a PhD candidate. Dr. Ellis-Behnke is 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 Therapeutics.

Terrence W. Norchi, MD, President and CEO of Arch Therapeutics, said, "This study provides independent evidence that AC5 can stop bleeding in animals being treated with an anticoagulant. This additional research represents an important confirmatory step by an outside group, highlighting an exciting feature of AC5 that differentiates it from many existing hemostatic solutions currently on the market. This is a key new finding in AC5's ongoing development path toward commercialization for use in humans."
