Arch Therapeutics Reports on Current Activities

CAMBRIDGE, MA--(Marketwired - Jul 30, 2013) - Arch Therapeutics, Inc. ( OTCQB : ARTH ) ("Arch" or the "Company"), a life science company and developer of AC5™, a novel product aimed at controlling bleeding and fluid loss in order to provide faster and safer surgical and interventional care, is pleased to provide a summary of current events.

Arch Therapeutics is developing products that make surgery and interventional care faster and safer by utilizing a novel approach to stop bleeding (referenced as "hemostasis"), control leaking (referenced as "sealant"), and provide other advantages during surgery and trauma care. AC5™ is based on a self-assembling peptide solution that creates a physical, mechanical barrier, which could be applied to bleeding organs or wounds to seal leaking blood and other fluids.

To date, we have devoted much of the work on our core technology to selecting the lead product composition, conducting initial safety and efficacy tests, developing reproducible and reliable analytical and manufacturing methods, and scale-up. We have also focused on developing relevant intellectual property rights via filing several patent applications in multiple jurisdictions for self-assembling peptides and methods of use thereof, all of which are pending. Much of this pre-clinical work is a necessary pre-requisite to the clinical-regulatory program, which we are currently designing.

The results of early data from preclinical tests have shown that AC5™ achieves hemostasis quickly and effectively. AC5™ can be directly applied as a liquid or sprayed, making it user-friendly and able to conform to irregular wound geometry, and is not sticky or glue-like, making it ideal for use in the setting of minimally invasive laparoscopic surgeries. Further, AC5™ is transparent, which should make it easier for surgeons or other healthcare providers to maintain a clear field of vision during a surgical procedure and prophylactically stop bleeding as it starts, which we call Crystal Clear Surgery™.

Preclinical testing to date has been conducted in a number of settings. One of the co-founders of our technology, Dr. Rutledge Ellis-Behnke, performed a significant portion of the preclinical experimentation at major academic institutions in Massachusetts (2001-2005) and Hong Kong (2004-2009). Some of the most significant findings from Dr. Ellis-Behnke's studies have been published. Importantly, we have further engaged both academic and private third party facilities in the United States, including in Massachusetts, and in Europe, including a successful collaboration with several parties at the National University of Ireland and the Royal College of Surgeons in Ireland, in order to further advance the technology to its current state. 

Company CEO, Dr. Terrence Norchi comments, "In the preclinical tests conducted to date, AC5™ has demonstrated improved average time to hemostasis ('TTH') during a range of surgical procedures compared to TTH when using a control substance, a saline control substance, a control peptide, and a cautery control substance during those same procedures. The results of those tests have shown a TTH of under 15 seconds when AC5™ was applied, compared to a TTH ranging from 80 to 300 seconds when various control substances were applied, depending on the nature of the control substance and procedure performed. To date, we have noted no ill effects or other adverse consequences. We believe that the peptide degrades into the naturally occurring amino acids from which it was originally synthesized, which are molecules that already exist in large quantities in the body. Our plans in the near-term are to focus our efforts on the development of AC5™ by pursuing additional preclinical studies and preparing for future clinical trials."
