Bioniche Life Sciences Inc. Release: Updates On MCC Phase III Bladder Cancer Study And E. coli O157:H7 Cattle Vaccine Regulatory Progress

BELLEVILLE, Ontario, March 23 /PRNewswire-FirstCall/ -- Bioniche Life Sciences Inc. , a research-based, technology-driven Canadian biopharmaceutical company, today announced that it has received Canadian regulatory approval to proceed with part one of its Phase III bladder cancer program in Canada and also confirmed that its E. coli O157:H7 cattle vaccine is proceeding through the regulatory pathway in the U.S.

Phase III Bladder Cancer Program Regulatory Update

The Biologics and Genetic Therapies Directorate of Health Canada has approved Bioniche's Clinical Trial Application for the first of two Phase III clinical trials using the Company's proprietary Mycobacterial Cell Wall-DNA Complex (MCC) for the treatment of bladder cancer. This follows the Company's announcement of a similar approval by the U.S. Food and Drug Administration (FDA) in February of this year.

Approximately 142,000 patients in North America and Europe are newly-diagnosed with superficial bladder cancer each year. Approximately 96,000 of these are high-risk cases, of which 30%+/- are refractory to standard therapy.

In this first part of the Phase III program, 105 patients will be involved in an open-label study showing the efficacy of MCC as therapy in superficial bladder cancer refractory (unresponsive) to Bacillus Calmette-Guerin (BCG). BCG is a live, attenuated strain of Mycobacterium bovis, the current standard therapy for bladder cancer, but one that is often associated with treatment-limiting side effects. This Bioniche study will be conducted in North America. Patient enrolment will commence in the second quarter of calendar 2006. The FDA is currently reviewing the IND for the second part of the Company's Phase III program, a randomized, double-blind, multi-centre study comparing MCC to BCG as first-line therapy in superficial bladder cancer at high risk of recurrence or progression. This study will take place in both North America and Europe.

E. coli O157:H7 Cattle Vaccine Regulatory Update

The U.S. Department of Agriculture (USDA) has been reviewing a data package submitted by Bioniche that outlines results of research studies using its proprietary E. coli O157:H7 cattle vaccine. The USDA has indicated that the supplied data is not sufficient to support a product registration. Bioniche intends to respond to the USDA by submitting additional study data that it believes will be supportive of the U.S. license for the vaccine.

In the Company's second quarter report, it was noted that the vaccine could be registered in the U.S. later this year, with a milestone target of Q2 to Q3, calendar 2006. Given the additional review by the USDA, this target may have to be adjusted.
