Phosphagenics Limited (ASX: POH) (AIM: PSG) (ADR/OTC: PPGNY) announced today positive results from pre-clinical studies of its TPM-02 dermal drug delivery technology formulated with retinoic acid, a leading topical treatment for severe acne and an active ingredient used in anti-aging cosmetics.

The proof of concept studies showed a three-fold increase in the amount of retinoic acid delivered into the skin when formulated with TPM-02 compared to a control formulation. Importantly, there was no retinoic acid detected in the bloodstream. TPM-02's ability to deliver an active ingredient to the dermis, the active layer of the skin, highlights the system's potential use in dermatologic and cosmetic products.

This study builds upon Phosphagenics' successes in delivering drugs, including insulin, through the skin without causing skin irritation, and further demonstrates that the TPM-02 technology can be utilized to deliver and hold an active ingredient in the skin, which is optimal in achieving maximum effectiveness from dermatological and cosmetic products.

"These proof of concept studies demonstrate the adaptability and flexibility of Phosphagenics' delivery technology, and we intend to leverage these results in pursuing opportunities in the dermatological and cosmetic fields," said Dr. Esra Ogru, Executive Vice President R&D at Phosphagenics. "The ability to deliver greater amounts of retinoic acid to the skin will produce more effective products for consumers, which is our objective in the areas of dermatology and cosmetics."

In addition to improving the dermal delivery of retinoic acid, Phosphagenics sees broader applications for its TPM-02 technology with additional pre-clinical studies showing potential in the dermal delivery of other compounds, such as coenzyme Q10 (CoQ10) and omega-3 fatty acids.
