About HspE7, Lead Product Candidate:

HspE7 is a novel CoVal(TM) fusion therapeutic vaccine for the treatment of diseases caused by the human papillomavirus (HPV), one of the most common causes of sexually transmitted diseases in the world. An estimated 80 percent of sexually active men and women are infected by genital HPV at some point in their lives. Approximately 5.5 million new sexually transmitted HPV infections are reported in the U.S. each year. At least 20 million people in the U.S. are already infected.

Precancerous HPV-related conditions can progress into life-threatening diseases, including cervical, anal, and head and neck cancers.

This press release contains forward-looking statements regarding a corporate reorganization, by way of a plan of arrangement, and the development of our HspE7 program. Actual results could be materially different from those implied by these forward-looking statements due to factors over which we have limited control, including but not limited to the risk that the reorganization may not be consummated, for any number of reasons, including the failure to obtain necessary court approvals or the failure to satisfy all of the closing conditions, our ability to continue as a going concern, our ability to enter into corporate partnering relationships (and the effects and terms of those relationships), difficulties inherent in the manufacture of commercial-grade clinical supplies, our ability to meet regulatory approval requirements, the development of our potential products, including HspE7, not proceeding as planned, clinical trial uncertainties, the risk that, if successfully developed, HspE7 may not be commercially successful and the effect of our limited cash resources. Please refer to our filings with Canadian securities regulators for more information on these and other applicable risks. We assume no obligation and expressly disclaim any duty to update any forward-looking statement to reflect events or circumstances after the date of this news release or to reflect the occurrence of subsequent events.
