Arch Therapeutics Reports Significant Wound Healing Results in Pre-Clinical Safety Study With AC5 Surgical Hemostatic Device

FRAMINGHAM, MA--(Marketwired - December 01, 2015) - Arch Therapeutics, Inc. (OTCQB: ARTH) (“Arch” or the “Company”), reports that use of its AC5 Surgical Hemostatic Device™ resulted in normal wound healing in a skin excision safety study in large pigs. The majority of AC5 treated wounds (n=18) showed full healing and minimal inflammation, with results comparable to those in control animals. Following 14 days of treatment with AC5™, the tissue response was stable and consistent with the advanced stages of biological healing. There was no evidence of abnormal wound healing. Testing of blood samples and other tissues from AC5™-treated animals similarly showed normal tissue and chemistry profiles.

Terrence W. Norchi, MD, president and CEO of Arch Therapeutics, said, “We are encouraged by these results, which show that once bleeding stops after use of AC5, wounds heal normally and with minimal inflammation. We continue to establish safety and biocompatibility with our AC5 device, while also focusing on the scale-up of AC5 product manufacturing and working with our colleagues in Europe to commence our first human trial.”

This study and associated testing were performed under Good Laboratory Practice (GLP) conditions using the same lot of AC5 prepared under Good Manufacturing Practices (GMP) for Arch’s planned upcoming clinical study in humans. Visual healing rate was normal for all wounds and wound-healing rate was normal for all time points. All observed organs appeared normal and all blood analysis parameters showed a normal reaction to wound creation and duration of wound healing.

We have submitted an application to a European regulatory authority to commence our first clinical trial of AC5, and we have received preliminary comments from such regulatory authority on our application. We have responded to those comments, and we expect to receive approval to proceed with our first clinical trial of AC5 during this fiscal quarter. Accordingly, the company is maintaining its previously announced estimated timeframe to commence the first clinical trial of AC5™ in humans by the end of 2015.
