Data Expected During Summer 2016 After Completion of 30-Day Follow-Up and Subsequent Statistical Analysis

FRAMINGHAM, MA -- (Marketwired) -- 06/06/16 -- Arch Therapeutics, Inc. (OTCQB: ARTH) ("Arch" or the "Company"), developer of the AC5 Surgical Hemostatic Device™ (AC5™) for use in controlling bleeding and fluid loss in order to provide faster and safer surgical and interventional care, announced today that it had completed patient enrollment in its first clinical study to assess the safety and performance of AC5 in humans. The study is being carried out in collaboration with CÚRAM, Science Foundation Ireland Centre for Research in Medical Devices and the Clinical Research Facility based at National University of Ireland Galway.

A total of 46 patients have been enrolled in this randomized controlled single-blind study, which is taking place in Ireland. The Company anticipates announcing the results from the study during summer 2016 after completion of the patient follow-up assessments (30-day) and subsequent statistical analysis. The endpoints include product-related adverse events and time to hemostasis. To date, no serious adverse events have been reported.

Terrence W. Norchi, MD, President and CEO of Arch Therapeutics, said, "This is yet another milestone for Arch Therapeutics on the path toward regulatory approval of AC5. Now that the planned number of patients have been treated, we are awaiting completion of the remaining 30-day follow-up assessments. We are eager to obtain the data when the statistical analysis is available, and we look forward to reporting the results later this summer."

The Company anticipates filing a CE mark application for AC5 during summer 2016 and is currently planning its next clinical-regulatory steps for both the EU and the US.

Professor Abhay Pandit, Director of CÚRAM, said: "CÚRAM are delighted to support Arch through this trial and in their drive to commercialize AC5."

The current study design is intended to assess safety and performance of AC5 during the course of a dermatological procedure performed on the 46 patients, of whom 10 were taking an antiplatelet medication, such as aspirin, during the study period, and was designed so that neither the patients nor the clinical personnel performing the 30-day follow-up assessments would be aware of whether a particular lesion had been treated with AC5 or a control. Patients participating in the study had at least two dermatological lesions removed surgically, of which one was randomly assigned to be treated with AC5 and the other lesion assigned to be treated with a control treatment.
