Ark Therapeutics Group PLC28 October 2005 Preliminary Results of VitorTM Study Show Clear Therapeutic Effect in Cancer Cachexia 28 October 2005 - Ark Therapeutics Group plc ("Ark") announces today that thepreliminary results of the VitorTM study in 200 patients with cancer cachexiaindicate that the product changes the pattern of weight loss in the three typesof cancer (colorectal, lung and pancreatic) in the study. Patients entering this study were all terminal cancer patients and had alreadylost an average of 15% of their body weight. A positive treatment effect withVitorTM was observed across the treatment group, irrespective of cancer type.Whilst initially continuing to lose weight over the first four weeks of thestudy, colorectal and lung cancer patients then gained weight over the nexteight weeks to study end (week 12) whereas placebo patients lost weight (VitorTMdaily rate of change +0.025lbs vs placebo -0.022lbs). Pancreatic cancerpatients (the more aggressive of the cancers studied), whilst not gaining weightafter the first four weeks of the study, exhibited a marked reduction in thedaily rate of weight loss compared with placebo (VitorTM -0.02lbs per day vsplacebo -0.06lbs per day) over the remainder of the study. The positive effectsof VitorTM treatment were also evident in the initial analysis of hand gripstrength. The initial results from this study, which is the first time VitorTM has beentested in humans in this disease, demonstrate a proof of principle in humansconsistent with that previously found in pre-clinical models and the novel modeof action reported in late 2004. Professor John Martin, Chief Scientific Officer at Ark, said: "The positiveeffects observed in this study of VitorTM would offer cancer patients a veryrelevant clinical benefit as weight loss and the associated weakness are some ofthe most distressing and dangerous aspects of late stage cancer." Nigel Parker, Chief Executive Officer, said "This first data cut looks veryinteresting and we look forward to completing the full study analysis todetermine what further activities may be required for regulatory filing. Thishas been a tremendous two weeks at Ark. With Trinam(R)'s low dose resultsshowing a tripling of haemodialysis access graft patency, our Finnishmanufacturing facility receiving the world's first(1) licence to produce a genemedicine for commercial supply, the EMEA accepting the CereproTM marketingauthorisation application for review and finally these first proof of principleVitorTM results, we have ended this intense period of newsflow in exceptionalshape." 1 Outside China A conference call for analysts will be held today at 09.00am BST.

The active ingredient was originally developed as a treatment for highblood pressure and is currently marketed in Japan and certain countries inEurope. VitorTM has been shown to up-rate the ability of mitchondria to produceenergy. In addition by working on the ubiquitin proteasome pathway, it preventsthe breakdown of muscle proteins (actin and myosin) and reverses the impairedmuscle protein production, which both occur as a result of the action ofchemicals secreted by the cancer tumour and lead to the weight loss.
