Barrier Therapeutics Announces Promising Results From On-Going Phase 2a Study of Pramiconazole in Onychomycosis

Novel Oral Broad-Spectrum Antifungal Agent Demonstrates Interesting Efficacy With Once Weekly Dosing

PRINCETON, NJ--(Marketwire - October 19, 2007) - Barrier Therapeutics, Inc. (NASDAQ: BTRX), a pharmaceutical company that develops and markets dermatology products, today announced promising results from its on-going Phase 2a proof-of-concept study with pramiconazole, its novel oral broad-spectrum antifungal product candidate, in patients with onychomycosis (nail fungus) of the toenails. Pramiconazole has previously demonstrated positive results in clinical studies in tinea pedis (athlete's foot), tinea corporis (ring worm), tinea cruris (jock itch), tinea versicolor, vaginal candidiasis and seborrheic dermatitis.

"Based on research thus far, pramiconazole may offer an important breakthrough in antifungal therapy, offering effective results with less frequent dosing than currently available drugs," said James Del Rosso, DO, Dermatology Residency Director, Valley Hospital Medical Center, Las Vegas, Nevada and Private Practice, Las Vegas, Nevada. Dr. Del Rosso will present highlights from this clinical trial later today at the 26th Anniversary Fall Clinical Dermatology Conference® in Las Vegas, Nevada.

Results from 18 patients at week 16 of the study, one month after completing once weekly treatment for 12 weeks, indicate a marked onset of clinical improvement in total signs and symptoms (p=0.001)(1) of onychomycosis as measured by nail plate thickening, discoloration and overall appearance of the affected toenail. Considering the slow outgrowth of toenails, clinical improvement at this early time point is potentially a key observation. In addition, 4 of 13 patients (31%) who were evaluated at three months post-treatment demonstrated both mycological cure and a significant(1) decrease in clinical signs and symptoms of the affected toenail. To date no patients have reached the final evaluation visit at week 48, nine months after the end of treatment.

"These data further demonstrate pramiconazole's broad spectrum activity against dermatophytes, yeasts and molds, and, given the encouraging mycological and clinical efficacy in nail fungus, we believe the program warrants full development in this highly prevalent infection," commented Dr. Braham Shroot, Chief Scientific Officer of Barrier Therapeutics. "Using data from this study combined with additional pharmacokinetic studies, we will determine the dosing regimens for future dose-ranging studies. Pramiconazole could address an unmet need for a new, more convenient, and possibly safer once weekly treatment option for the 35 million people in the United States who suffer from the chronic, recurring condition."

Patients in the Phase 2a open label single-arm study were dosed with 200 mg of pramiconazole once weekly for 12 weeks, and then are being followed for an additional 36 weeks after the initial treatment period. Current data indicate the drug has been well-tolerated, and there have been no reports of drug-related serious adverse events. A total of 19 patients have been enrolled in this on-going study. Final results for all patients enrolled in this Phase 2a trial will be presented at a future scientific meeting.

Copies of the slides including photographs presented by Dr. Del Rosso will be available on the Company's website under "Scientific Publications/Articles - 2007" in the "News Releases" section at www.barriertherapeutics.com. Dr. Del Rosso has not been associated with any clinical studies conducted with pramiconazole.

About Onychomycosis

Onychomycosis is a chronic and recurring fungal infection of the toenails or the fingernails resulting in thickening and discoloration of the nail. Without treatment, the disease sometimes can result in pressure, irritation, serious pain and disability. In the United States, onychomycosis is estimated to affect up to 35 million people.

About Pramiconazole (previously known as Azoline)

Pramiconazole, a novel antifungal agent, is being developed by Barrier Therapeutics as a potential once weekly treatment for chronic fungal infections such as onychomycosis (nail fungus), as well as a potential short course treatment for acute skin and mucosal fungal infections. In vitro pramiconazole has been shown to possess broad spectrum potency against dermatophytes, yeasts and molds. In March 2007, the Company reported positive results from a Phase 2b dose ranging study with pramiconazole in tinea versicolor. Previously, the Company has also shown positive results in Phase 2a trials with pramiconazole in tinea pedis (athlete's foot), tinea corporis (ring worm), tinea cruris (jock itch), tinea versicolor, vaginal candidiasis and seborrheic dermatitis. The Company is currently seeking to establish a commercial partnership to help fund the further development of this product.
