AURORA, ONTARIO--Interferon-a has been successfully delivered both dermally and transdermally, without the need for an injection, utilizing the Biphasix(tm) delivery system in a study of seventeen healthy human volunteers.

In a presentation to the Controlled Release Society in Boston, Professor Marianna Foldvari, of the College of Pharmacy and Nutrition at the University of Saskatchewan, presented the results of a study of the delivery of therapeutic proteins through human skin. The study showed a significant increase in anti-viral activity in the skin and in the blood following the application of an interferon-a-Biphasix(tm) patch when compared to a placebo.

"The results indicate significant levels of interferon-a in the skin and blood," said Dr. Foldvari. "This new delivery technology may also prove useful for the injectionless delivery of other protein therapeutics such as insulin. "

Interferons are prescription drugs presently given by injection to treat human papilloma virus ("HPV"), as well as other diseases including multiple sclerosis and hepatitis. Helix is developing an interferon-a Biphasix(tm) cream to combat HPV, a sexually transmitted disease linked to cervical cancer, that affects more than 24 million North Americans.
