SNOA Sonoma Pharmaceuticals Inc

Sonoma Pharmaceuticals, Inc. (Nasdaq: SNOA), today announced that results from a study into the use of the company’s proprietary high-strength Performance-Stabilized HOClTM in the management of acne vulgaris were presented at the Practical Symposium Dermatology Conference in Colorado. (http://intradermeu.com/downloads/IntraDerm_AcnePoster_v3_08-02-18.pdf ) and https://www.ncbi.nlm.nih.gov/pubmed/19459079).  The study results, as well as the results of Sonoma’s previous HOCl acne studies (total of 127 patients), were presented by the principal investigator, Mark Steven Nestor, M.D., Ph.D., who is Director of the Center for Clinical and Cosmetic Research, Aventura Florida and Voluntary Associate Professor in the Departments of Dermatology and Cutaneous Surgery and the Division of Plastic Surgery at the University of Miami Miller School of Medicine in Miami, Florida.

“This study truly demonstrates that both of these new HOCl products show significant efficacy in the treatment of mild-to-moderate acne,” said Dr. Nestor.  “And in doing so, both the gel and the solution were extremely well tolerated. Additionally, based on the safety profile of HOCl, I have no problem recommending HOCl topical treatment to young children or women who are pregnant or trying to get pregnant.  I can envision a time in the very near future when this will become a standard protocol in the treatment of acne vulgaris either alone or in combination with other treatments.”

The primary objective of the acne vulgaris pilot study was to evaluate the activity of Sonoma’s high-strength Performance-Stabilized HOClTM (both solution and gel) as effective topical products for mild-to-moderate acne vulgaris. Twenty patients with mild-to-moderate acne vulgaris were treated for 12 weeks with either solution or gel. The use of HOCl solution resulted in a statistically significant decrease in inflammatory (66%: p=0.0002) and non-inflammatory lesions (43%: p=0.002).  Sonoma’s HOCl gel also produced a statistically significant decrease in inflammatory (64%: p=0.003) and non-inflammatory lesions (43%: p=0.005).  In terms of product tolerability, both subjective and objective local skin reactions were minimal to non-existent.  No adverse events were reported.

This current study confirmed the results of the two prior studies, (n=127 patients), which included comparisons of Sonoma’s HOCl solution to placebo and benzoyl peroxide and showed a similar improvement in the reduction of lesions in both mild-to-moderate and moderate-to-severe acne.

A Double-Blinded, Placebo-Controlled, Parallel-Group, Randomized, Clinical Trial.” J Derm Treatment 20, (5) 289-292, 2009 and 2) Draelos A. “The Efficacy and Tolerability of a Novel Acne Treatment.” Sonoma Study Report, October 2016).

Sonoma plans to initiate in the near term a new double-blind placebo-controlled trial with a larger patient group, investigating the efficacy of Performance-Stabilized HOCl on moderate to severe acne vulgaris.

Sonoma’s Performance-Stabilized HOCl as part of an acne management regimen will become available in the United States in the winter of 2018.
