Study 904 will take place inapproximately 40 centres in Europe and Israel and aims to recruit up to 250patients. CereproTM has already shown highly significant results in two clinical efficacyand safety studies, almost doubling mean survival times and was well toleratedwith an acceptable safety profile. CereproTM, a European and US Orphan Drug,is manufactured in Ark's facility in Kuopio, Finland which has recently receivedthe world's first commercial licence for gene medicine production1. The Companyhas also announced today, in a separate press release, that its filing forMarketing Authorisation Approval in Europe has been accepted by the Europeanmedicines regulatory authority, the EMEA, as valid and the formal review is nowable to commence. Dr David Eckland, Research and Development Director at Ark, commented: "Ark is apioneer in the field of gene therapy and CereproTM is potentially the first genetherapy product1 that could be approved in this fast emerging area. We have beenvery pleased with the helpful and constructive approach taken by the variousEuropean regulatory agencies and have recently finalised the importantmanufacturing aspects. Results from the first two efficacy and safety studieshave been extremely encouraging and with the good quality of life seen in theextended survival period, CereproTM offers hope for patients who suffer fromthis dreadful disease." Dr Nigel Parker, Chief Executive Officer of Ark, commented: "Ark has madetremendous progress in all its key gene-based medicine programmes this year. Asthe results come through, it is becoming clear that DNA-based medicines arecoming of age, offering large clinical benefits with good safety profiles inhitherto difficult to treat diseases. Ark is working diligently to take up itsleadership position in this new medical area." 1 Outside China A conference call for analysts will be held today at 09.00am BST.

The current standard therapy involves surgicallyremoving the solid tumour mass (when possible) and initiating radiotherapy and/or chemotherapy. Even with the latest approved treatments, most patients diewithin one year of diagnosis, with average survival being about eight months.Little therapeutic progress has been made in recent years and the prognosis formalignant glioma patients is poor. A high unmet clinical need exists for newtreatments that prolong life in this devastating disease. There areapproximately 16,000 cases of malignant glioma in the EU which are operable. CereproTM CereproTM is an adenoviral mediated gene based medicine (ad.HSV tk) given bymultiple injections into the healthy brain tissue of patients following surgicalremoval of the solid tumour mass. In the following days, ganciclovir, is givenintravenously. Once treated, healthy brain cells surrounding the site where thetumour was removed express the enzyme thymidine kinase. This converts theganciclovir to a substance which specifically kills dividing cells. The healthyneurones surrounding the tumour in the brain are non-dividing and are thereforenot susceptible to this substance. In this way CereproTM harnesses healthybrain cells to help prevent a new tumour from growing. Ark Therapeutics Group plc Ark is an emerging healthcare group (the "Group") now entering thecommercialisation phase, with one product introduced into hospitals and threefurther lead products in late stage clinical development. Capitalising on overten years of research in vascular biology and gene-based medicine, Ark has abalanced portfolio of proprietary healthcare products targeted at specific unmetclinical needs within vascular disease and cancer. These are large and growingmarkets, where opportunities exist for effective new products to generatesignificant revenues. Ark's products are sourced from related but largely non-dependent technologieswithin the Group and have been selected to enable Ark to take each productthrough development and to benefit from Orphan Drug Status and/or Fast TrackDesignation, as appropriate. The Group generally retains ownership of itsproduct candidates throughout clinical development. Ark has secured patents orhas patent applications pending for all its lead products in principalpharmaceutical markets and retains the right to market its lead products in thekey North American and European markets.
