Ark's Vitor™ commences patient enrolment into Phase III pilot study

London, UK, 27 August 2008: Ark Therapeutics Group plc ("Ark" or the "Company") today announces that enrolment of patients into its Phase III pilot study for VitorTM (Study 208) has commenced. VitorTM is Ark's product to treat cachexia (involuntary muscle wasting) associated with cancer.

Study 208 is a blinded, randomised, placebo controlled, multicentre trial in up to 64 patients being conducted in five countries in Europe. The trial will study the effect of VitorTM on patients with non-small cell lung cancer who are already experiencing clinical signs of cachexia. Patients will be assessed for their rate of muscle wasting during an initial blinded study run-in period of up to 6 weeks, and thereafter randomised to active or control treatment for a further 12 week period. Total weight loss, lean body mass and other physical markers of cachexia will be assessed using a variety of methodologies. The study results will provide data to support the design of the final Phase III programme.

VitorTM has been awarded Fast Track Status by the FDA reflecting the high clinical need for an effective product to treat cachexia, which affects up to 70% of patients with solid tumours and is the most frequently reported cause of death in these patients. A Special Protocol Assessment (SPA) process was opened with the FDA in 2007. The Company is expected to enter full Phase III development in 2009 following completion of this pilot study. 

A Phase II/III study of VitorTM in 165 patients has already been completed in the USA and Europe, where treatment showed a significant effect compared with placebo in reducing the rate of daily weight loss in patients with small cell lung and colon cancer.

Nigel Parker, CEO of Ark, commented: "Having secured approvals from all the various committees in the countries involved in the trial, we are pleased to report this clinical progress on VitorTM with patients entering the trial as expected. We look forward to providing an update on the trial's progress in due course."

Notes to Editors

VitorTM and cachexia in cancer

Vitor™ is an oral small molecule therapy for the treatment of muscle wasting (cachexia), a secondary, often fatal, condition commonly seen in patients with cancer. The active ingredient was originally developed as a treatment for high blood pressure and is currently marketed in Japan and certain countries in Europe. Pre-clinical work has shown Vitor™ up-rates the ability of mitchondria to produce energy. In addition, by working on the ubiquitin proteasome pathway, it prevents the breakdown of muscle proteins (actin and myosin) and reverses the impaired muscle protein production, which both occur as a result of the action of chemicals secreted by the cancer tumour and lead to weight loss. Ark estimates that 1.5 million new cases of cancer cachexia occur every year in the US and Europe yet few treatment options currently exist.

Ark Therapeutics Group plc

Ark Therapeutics Group plc is a specialist healthcare group (the "Group") addressing high value areas of unmet medical need within vascular disease, wound care and cancer. These are large and growing markets, where opportunities exist for effective new products to generate significant revenues. With four marketed devices, Kerraboot®, Kerraped®, Flaminal® and Neuropad®, and three further lead pharmaceutical products in late stage clinical development: Cerepro®, Vitor™, and Trinam®, the Group is transitioning from an R&D company to a commercial, revenue generating business.

Ark's own products are sourced from related but largely non-dependent technologies within the Group and have been selected to enable them to be taken through development within the Group's own means and to benefit from Orphan Drug Status and/or Fast Track Designation, as appropriate. This strategy has allowed the Group to retain greater value and greater control of clinical development timelines, and to mitigate the risks of dependency on any one particular programme or development partner. Ark has secured patents or has patent applications pending for all its lead products in principal pharmaceutical markets. 

Ark has its origins in businesses established in the mid-1990s by Professor John Martin and Mr Stephen Barker of University College London and Professor Seppo Yla-Herttuala of the AI Virtanen Institute at the University of Kuopio, Finland, all of whom play leading roles in the Company's research and development programmes.
