TSX Venture: QPT

EDMONTON, June 2 /PRNewswire-FirstCall/ - Quest PharmaTech Inc. (TSX-V: QPT), ("Quest" or the "Company"), today announced that its 12-patient, Phase I clinical study entitled "ACP-SL017 Topical Gel: A Phase I Study for the Photodynamic Therapy of Actinic Keratosis" has met both its primary and exploratory objectives.

"We are delighted to have received, for the first time, clinical validation for our SonoLight Technology in a dermatological application," said Madi R. Madiyalakan, CEO of Quest. "Actinic Keratosis is a pre-cancerous skin condition usually caused by prolonged accumulated sun exposure which can progress to squamous cell carcinoma, a potentially life-threatening form of skin cancer, unless treated by a dermatologist or other physician. This trial successfully demonstrated that cutaneous photodynamic therapy (PDT) with SL017 appears safe and is well tolerated. In addition, our unique approach is designed to overcome some of the limitations associated with other commercially available PDT treatments for Actinic Keratosis."

Actinic Keratosis has a global incidence of approximately 10 to 15% in the Caucasian population and the American Medical Association estimates the U.S. market for the treatment of Actinic Keratosis to be about US $250 million.

The primary objective of the Phase I study, which was conducted in Canada, was to determine the cutaneous and systemic toxicity of the topically-applied photoactive drug, SL017, with and without photoactivation. The exploratory objective was to evaluate the efficacy of SL017 with and without photoactivation in the treatment of Actinic Keratosis. The study parameters employed included physician clinical assessment, patient symptomatic assessment, skin photography, blood chemistry, urinalysis, electrocardiogram and skin biopsy. The study was conducted at clinical sites in Edmonton and Montreal.

The study met all the objectives address
