Arch Therapeutics Provides Skin Sensitization Study Status Update

FRAMINGHAM, Mass., June 26, 2018 (GLOBE NEWSWIRE) — Arch Therapeutics, Inc. (OTCQB: ARTH) (“Arch” or the “Company”), developer of liquid, gel and solid hemostatic and wound care devices, provided an update today in which it announced that in the recently initiated skin sensitization study of AC5TM Topical Gel (AC5), two-thirds of the applications of AC5 in the repeat dosing induction phase have occurred and the study remains on schedule.

The sensitization study protocol was designed by Arch and its subject matter experts, and it incorporates recommendations provided by the Food and Drug Administration (FDA or “the Agency”). The study, designed as a single-center, prospective, clinical investigation, in approximately 50 healthy subjects, comprises an induction phase separated from a challenge phase by a rest period.

During the induction phase, AC5 on a patch is applied to each subject’s back three times weekly over 21 days for a total of 9 applications. With each re-application, the skin beneath the patch is evaluated, and any findings are scored per protocol. After a 14-day rest period, subjects enter the challenge phase, receive one additional application of AC5, and after a two-day rest period, are evaluated over 48 hours. If significant positive reactions occur subjects may be re-challenged in order to provide further information. 

The Company is pleased to report that two-thirds of the induction phase applications have been completed and the study remains on schedule to conclude in the third calendar quarter of 2018.

Terrence W. Norchi, MD, President and CEO of Arch, said, “While the study and report must be completed before we can draw conclusion, we remain optimistic about the outcome based on the results of the prior study for sensitization that was performed in animals. We are also pleased that the study remains on budget, and we now anticipate that our corporate cash runway has extended into the fourth calendar quarter of 2018.”

The study is intended to support the Company’s 510(k) notification for its AC5 Topical Gel, which is expected to be filed by the end of the third quarter of calendar 2018.
