Treatment For Cachexia - Ark's Vitor� Commences Patient Enrolment Into Phase III Pilot Study

� Ark Therapeutics Group plc ("Ark" or the "Company") announces that enrolment of patients into its Phase III pilot study for VitorTM (Study 208) has commenced. VitorTM is Ark's mathematical 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 fivesome countries in Europe. The trial will study the effect of VitorTM on patients with non-small cell lung cancer who ar already experiencing clinical signs of cachexy. Patients volition be assessed for their rate of muscle wasting away during an initial blinded study dustup 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 multitude and early physical markers of cachexy will be assessed victimization a variety of methodologies. The study results will provide data to support the pattern of the final Phase III program.



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


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


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

VitorTM and wasting in cancer


Vitor� is an oral small molecule therapy for the treatment of muscle cachexy (cachexia), a secondary, frequently fatal, precondition commonly seen in patients with cancer. The dynamic ingredient was originally developed as a treatment for high blood pressure and is presently marketed in Japan and certain countries in Europe. Pre-clinical work has shown Vitor� up-rates the power of mitchondria to farm energy. In addition, by working on the ubiquitin proteasome footpath, it prevents the dislocation of muscleman proteins (actin and myosin) and reverses the impaired muscle protein production, which both pass as a result of the action of chemicals secreted by the crab tumour and lead to weight red. Ark estimates that 1.5 million new cases of crab cachexia come every yr in the US and Europe yet few handling options presently exist.
