Ark Therapeutics Group PLC02 May 2007 Ark Therapeutics Group plc Ark commences clearance process for Trinam(R) Phase III trial with US Recombinant DNA Advisory Committee application 2 May 2007, London, UK: Ark Therapeutics Group plc announces that it has filedits application to the US Recombinant DNA Advisory Committee (RAC) to obtainclearance for its planned Phase III US clinical study of Trinam(R), Ark's novelgene-based therapy to prevent haemodialysis access graft blockage. The RAC is expected to make a decision by the end of its meeting scheduled for19-21 June. Ark has previously obtained clearance for a 200+ patient study ofTrinam(R) from the RAC and this new application reflects the revisedarchitecture following the successful end of Phase II meeting with the FDA,announced on 11 January 2007. Commenting on the announcement Ark's CEO, Dr Nigel Parker, said: "This is an important stage in the clearance process to allow us to commenceTrinam(R)'s pivotal Phase III study. RAC hearings are held in public and it isimportant that as development progress is made with such new DNA-based medicinesthe public has the opportunity to comment. The RAC is an independent body tothe FDA and we need to obtain this clearance alongside our work with the FDA.Trinam(R) continues to progress well and we look forward to giving furtherupdates in due course."

At the end of the access graft surgery procedure, thecollar is fitted around the outside of the vein/graft join. The Ad-VEGF-Dsolution, which reduces the likelihood of blood clots and intimal hyperplasia,is then injected into the space between the wall of the collar and the bloodvessel. This unique method of administration of the gene localises its deliveryto the target tissue site, maximising efficacy, avoiding systemic distributionand thus minimising the potential for side effects. Trinam(R) has undergone a Phase II clinical study, which has shown encouragingearly efficacy results, with grafts of treated patients remaining functional fordialysis on average between two and four times longer than controls. For theprimary end point of safety, no quantifiable systemic distribution of Trinam(R)was found and the product is well tolerated. No serious side effects wereexhibited other than those consistent with the nature of the operation andcondition. After consultation with the FDA in January 2007 Ark announced that it intendedto undertake a small pre-clinical study on Trinam(R), investigatingbiodistribution in an "end-to-side" procedure for surgical placement of thegraft. If the results of this study are in line with expectations, it willallow the Phase III trial to include this procedure alongside the "end-to-end"placement procedure. Pending SPA agreement, the Phase III study is expected tocommence around mid-2007 and to last for approximately 18 months. The Phase III study is being planned as a multi-centre, randomised, controlledtrial of up to 250 patients in which the efficacy and safety of Trinam(R) willbe investigated in patients with end stage renal disease (ESRD) requiringvascular access for haemodialysis. Patients with ESRD will be randomised toreceive either Trinam(R) in addition to standard care or standard care alone atthe time of surgical placement of a synthetic PTFE graft for vascular access.The primary endpoint of the trial will be the time to graft failure. Recombinant DNA Advisory Committee The US National Institutes of Health (NIH) established the RAC on October 7,1974 in response to public concerns regarding the safety of manipulating geneticmaterial through the use of recombinant DNA techniques. Although the RAC'smembership and responsibilities have evolved over time with scientificunderstanding and developments in this technology, it continues to serve theNIH, as well as the scientific and lay publics, as a critically important forumfor open, public deliberation on the panoply of scientific, ethical, and legalissues raised by recombinant DNA technology and its basic and clinical researchapplications. Over the course of the Committee's existence, transparency andaccess have been its defining characteristics, enabling public acceptance of acritically important technology and creating an environment in which science canadvance in an informed, safe, and ethical manner. The RAC comprises experts in a wide range of scientific and medical disciplinesand also includes ethicists and members of patient and other lay communities.Because of the dedication, effort, and thoughtful contributions of its membersover the past 30 years, the RAC has been a vital national forum promotingcritically important scientific progress in a transparent, responsible, and safemanner and enhancing public trust in the science. 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, woundcare and cancer. These are large and growing markets, where opportunities existfor effective new products to generate significant revenues. With two marketeddevices, Kerraboot(R), and Flaminal(R), and three further lead pharmaceuticalproducts in late stage clinical development: Cerepro(TM), Vitor(TM), and Trinam(R), 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-dependenttechnologies within the Group and have been selected to enable them to be takenthrough development within the Group's own means and to benefit from Orphan DrugStatus and/or Fast Track Designation, as appropriate. This strategy has allowedthe Group to retain greater value and greater control of clinical developmenttimelines, and to mitigate the risks of dependency on any one particularprogramme or development partner. Ark has secured patents or has patentapplications pending for all its lead products in principal pharmaceuticalmarkets. Ark has its origins in businesses established in the mid-1990s by Professor JohnMartin and Mr Stephen Barker of University College London and Professor SeppoYla-Herttuala of the AI Virtanen Institute at the University of Kuopio,Finland, all of whom play leading roles in the Company's research anddevelopment programmes.
