Psioxus Therapeutics converts GBP 1 million in loan notes from the Wellcome Trust

LONDON – 13 September 2012 – PsiOxus Therapeutics, Ltd. (PsiOxus) today announced the conversion of almost £1 million ($1.5 million) of loan notes from the Wellcome Trust, a leading global charitable foundation. The loan conversion follows a Series B round of equity financing totaling £22 million ($34 million) closed in July 2012.

The loan notes derive from a Translation Award from the Wellcome Trust for the development of a systemically available oncolytic vaccine, ColoAd1, through a phase I clinical trial for the treatment of colorectal cancer. The clinical trial will be initiated later this year.

ColoAd1 is a unique therapeutic candidate developed using the evolutionary principle of natural selection to generate an oncolytic vaccine with optimal anti-cancer properties. The vaccine is injected into the bloodstream and can replicate in and destroy cancer cells but not normal cells. Each infected cell produces thousands of new copies of ColoAd1, which then spread to nearby cancer cells and destroys them as well. The approach thus represents a new generation of ‘self-amplifying’ cancer therapy that has both a direct tumor killing and cancer vaccine effect.

Commenting on the announcement, Dr Richard Seabrook, Head of Business Development at the Wellcome Trust, said, “Oncolytic vaccines represent a promising new treatment option and the Wellcome Trust is pleased to reinforce our support for further investigation of this new approach to cancer therapy.”

Dr John Beadle, CEO of PsiOxus, commented: “This continued support from the Wellcome Trust, the UK’s leading biomedical foundation, will be instrumental in taking ColoAd1 through to late stage clinical studies.”
