Helix Receives Approval to Open Sites in Germany for its Ongoing Clinical Trial With Topical Interferon Alpha-2b in Patients With Ano-Genital Warts

AURORA, Ontario, Sept. 22 /PRNewswire/ -- Helix BioPharma announced today that it has received the necessary regulatory approvals to open clinical sites in Germany to expand upon its clinical trial with Topical Interferon Alpha-2b in patients with ano-genital warts, which is presently underway in Sweden.

"We are pleased to have received approval to open these additional clinical sites," said John Docherty, President of Helix BioPharma. "The opening of sites in Germany will grant us access to expanded clinical resources and a larger patient pool in order to enhance the recruitment rate of our trial."

The opening of additional sites in Germany is intended to compensate for a lower than expected patient enrollment rate thus far in Sweden. These sites have been added in order to speed the pace of enrollment to support Helix BioPharma's objective of completing patient enrollment by the end of the Company's fiscal fourth quarter, ending July 31, 2009.

About the Clinical Trial

The trial is designed to assess the efficacy and safety of Topical Interferon Alpha-2b compared with placebo using a double blind, randomized design over an examination period of four months per patient. One hundred twenty patients are to be enrolled in the trial. Half will receive a placebo and half will receive Topical Interferon Alpha-2b. Only female subjects are to be enrolled in the trial in order to avoid inter-sex treatment variations. Trial subjects will self-administer Topical Interferon Alpha-2b twice daily for five consecutive days per week over a treatment period of eight weeks, with a follow-up visit at 16 weeks. The primary endpoint for the trial will be comparison of the proportion of patients with complete clearance of their baseline lesions during the eight week treatment period.

Dr. Pal Wolner-Hanssen of the University hospital in Malmo MAS, Sweden will remain the overall coordinating investigator for the trial, and Professor Dr. med. Eggert Stockfleth of the Department of Dermatology, Skin Cancer Center Charite, Universitatsmedizin Berlin will oversee the German study activities specifically.

About Ano-Genital Warts

Ano-genital warts result from HPV infection of the external genitalia, and can manifest as outwardly visible growths of varying sizes and shapes in both men and women. Each year in the United States alone, there are over 750,000 new cases of ano-genital warts.

About Topical Interferon Alpha-2b

Interferon Alpha-2b is an immune system modulator that is active against a variety of HPV-induced lesions. Interferon Alpha-2b is thought to function by triggering an antiviral response within infected cells, by activating certain intracellular enzymes which cause degradation of viral RNA, and by mobilizing the body's natural immune system to destroy the infected cells. Interferon Alpha-2b has been widely used commercially as a treatment for ano-genital warts caused by HPV, but is not generally favoured due to the fact that conventional administration requires painful intradermal injection by a medical professional. Furthermore, intradermal injection is restricted to visible lesion administration, while HPV infection is often characterized by both visible and non-visible (i.e. sub-clinical) lesions. Helix's Topical Interferon Alpha-2b is expected to offer a safe, discreet, self-administered, pain-free therapy that can be broadly applied across the entire affected tissue area. Helix anticipates that this will prove highly advantageous not only from a patient compliance perspective, but also from an efficacy standpoint.
