Circadian Technologies Limited Announces Major Development Agreement With Ludwig Institute For Cancer Research (LICR) And Licentia Limited

MELBOURNE, Australia, NEW YORK and HELSINKI, Finland, May 1 /PRNewswire- FirstCall/ -- Circadian Technologies Limited today announced that, in collaboration with one of the world’s leading cancer research organizations, the Ludwig Institute for Cancer Research (“LICR”) and the commercial arm of the University of Helsinki, Licentia Ltd. (“Licentia”), it has formed a new company, Vegenics Limited (“Vegenics”), to develop and commercialize the intellectual property and technology of LICR and Licentia with respect to molecules known as Vascular Endothelial Growth Factors (VEGF).

Vascular Endothelial Growth Factors are a family of proteins that play an important role in promoting the growth of new blood vessels and maintenance of existing blood vessels. The approach of inhibiting VEGF and thus restricting blood and nutrient supply to tumours has potential in the treatment of cancer.

Circadian will make an initial equity injection of A$4 million into Vegenics, which will be 50% owned by Circadian and 50% by LICR and Licentia. Vegenics will initially focus on developing peptide and antibody antagonists to two forms of VEGF (VEGF-C and VEGF-D) as anti-tumour agents.

It is currently the intention of Vegenics to raise a minimum of A$16 million additional new equity within 12 months, by way of an ASX listing or private equity raising at a market capitalisation in excess of A$50 million.

Commenting on the transaction Mr. Edward A. McDermott Jr., President and SEO of LICR stated, “We are very excited by the opportunity to work with one of the pioneers of the Australian biotechnology industry, in a close and collaborative manner. We look forward to advancing LICR’s cancer discovery program to potential clinical development. The Circadian model, which is now represented in the Vegenics collaboration, is one that has great appeal to research discovery organizations such as ours who need vehicles to translate basic and important discoveries into products that benefit cancer patients.”

Dr. Timo Tormala, CEO of Licentia Ltd. commented, “The work undertaken by Professor Kari Alitalo and his colleagues in Helsinki and Doctors Steven Stacker and Marc Achen in Melbourne is recognized as being seminal to the field of angiogenesis. We are delighted that we can now move to translate these discoveries into clinical candidates through the Vegenics collaboration.”

Mr. Leon Serry, Managing Director of Circadian noted, “Circadian has, over its 21 years, been totally committed to working with the excellence of the medical research community in early stage discoveries. The teams at LICR and the University of Helsinki are world leaders in their fields who share our passion to provide better and safer medicines for cancer patients. We believe that targeting tumor angiogenesis, as we will do in the Vegenics development plan, may provide better treatments in cancer therapy in the forthcoming years.”

In February 2004, Avastin(R), a therapeutic antibody designed by Genentech Inc. to inhibit VEGF-A, received FDA approval as a first-line combination therapy for patients with metastatic cancer of the colon or rectum. Genentech advised in January 2006 that 2005 US sales of Avastin were US$1.1 billion, up from US$500 million in 2004.

LICR and Licentia have developed an extensive patent portfolio covering VEGF-C and VEGF-D and antagonists to these molecules over the past 10 years arising from discoveries made by LICR Melbourne Branch scientists, Associate Professor Steven Stacker and Associate Professor Marc Achen and Professor Kari Alitalo of the University of Helsinki. LICR and Licentia have exclusively licensed to Vegenics all of their jointly owned technology covering VEGF-C and VEGF-D antagonists as therapeutic and diagnostic agents, subject to Vegenics raising A$16 million of new equity within 24 months and subject to the rights of existing licensees.

The licence and shareholder agreements between the parties are subject to patent and legal due diligence being completed by Vegenics by the end of June 2006.

The licensed patent family comprises more than 50 granted patents in the US, Europe, Japan and Australia and over 400 pending patent applications worldwide.

In consideration of the transaction LICR and Licentia have agreed to share with Vegenics any licensing or royalty income they receive from existing third party licences under the IP estate.

The Board of Vegenics will be chaired by Mr. Leon Serry, Managing Director of Circadian, and will comprise Mr. Robert Klupacs of Circadian as Managing Director; Mr. Graeme Kaufman of Circadian as Executive Director; Dr. Jonathan Skipper, Executive Director for Intellectual Property and Licensing, LICR; Dr. Andrew Simpson, Executive Director for Programs and Operations, LICR; and Dr. Timo Tormala, President and CEO of Licentia Ltd., as Non-Executive Directors.
