Technology License with Transgene: Product TG4010 Interim Results

MELBOURNE, Australia, 24 January 2008--Virax Holdings Limited, (ASX: VHL), advises that Transgene SA of Strasbourg, France, reported that its therapeutic vaccine TG4010 showed promising preliminary Phase IIb data in advanced non-small cell lung cancer when used as an adjunct to first line chemotherapy. TG4010 uses Virax’s Co-X-Gene™ technology under the stated License Agreement between the Company and Transgene. Transgene said the trial confirmed the favourable safety profile of TG4010 when associated with chemotherapy and that based upon local evaluations, results are so far showing a positive trend in favour of the combination of TG4010 with the chemotherapy.

Virax’s CEO, Larry Ward, said “the data is encouraging. Transgene are making great progress with both this product and their therapeutic vaccine, TG4001, for the treatment of pathologies relating to human papilloma virus (HPV) infection that can lead to cervical cancer. The advancement of both Transgene products into late stage development exemplifies the intrinsic value of the Co-X-Gene™ technology intellectual property and the Transgene Sublicense. We look forward to the presentation by Transgene of the full trial data for TG4010 later in the year.”

The Transgene Press release is attached.

These are TG4001 – a treatment for pathologies relating to human papilloma virus (HPV) infection that can lead to cervical cancer - and TG4010 – a treatment for non-small cell lung cancer.

This was reported to the ASX in the Company’s announcement of 13 March 2007 and is referred to as the “Transgene Sub-licence”. Both TG4001 and TG4010 are in advanced development with Phase III trials of TG4001 planned for 2008 and Phase IIb studies of TG4010 currently underway.
