Ark receives positive feedback from MHRA scientific advice meeting on EG013 for foetal growth restriction 

London, UK, 4 September 2009 - Ark Therapeutics Group plc ("Ark" or the "Company") today announces that it has received positive feedback from a formal scientific advice meeting with the Medicines and Healthcare products Regulatory Agency ("MHRA") regarding the pre-clinical toxicology and Phase I trial requirements for EG013, an adenovirally mediated VEGF based product being developed to treat severe foetal growth restriction ("FGR"). The MHRA commented on the nature of the pre-clinical models, toxicology programme and the design of a Phase I trial.

The MHRA concluded that the choice of species and overall design of the toxicology programme, including a series of in vitro studies using human placenta, are suitable to support a Phase I study. The nature and quality of the proposed vector are also suitable, and the release characteristics for the vector were clarified. The outline design of the Phase I study was considered suitable for a first-in-man study, and the entry criteria were clarified.

Severe foetal growth restriction is often a terminal condition in which insufficient blood supply to the placenta results in serious growth retardation, leading to premature death or undesired termination of a baby or long term neurological problems in surviving infants. The problem is usually first diagnosed around 20 weeks into pregnancy and at present there is no effective treatment.

Results from the first two trials of EG013 in a pre-clinical model of placental blood flow have shown that a single treatment with EG013, given directly into the mother's uterine artery, increased blood flow to the placenta by 25%, and that the effect was maintained for 50 days. Biodistribution data have shown no long term presence of the vector in the foetal tissues, as is essential for this form of gene therapy. If this efficacy is confirmed in human studies, a therapy with this magnitude and duration of effect could allow the foetus to grow satisfactorily to a stage where caesarean delivery of a healthy baby could be reliably performed. Ark has chosen the short form of VEGF-D as the most suitable agent to be used in FGR. The gene for this agent will be delivered using the standard Ark adenoviral platform, as developed in the Company's Kuopio centre. Work on this project is continuing in both Finland and the UK. 

Foetal growth restriction, in its various forms, affects approximately 60,000 babies in the USA and Europe. The work is being undertaken as a collaboration between Ark's scientists at University College London (UCL) and the UCL Department of Obstetrics and Gynaecology. In addition, Ark has formed a collaboration with the Department of Maternal and Foetal Medicine at the University of Manchester, to utilise their expertise in assessing the effect of EG013 on human placenta in vitro.

Commenting on the meeting with the MHRA, Dr David Eckland, Director of Research and Development at Ark, said: "Foetal growth restriction is a very distressing condition and EG013 has already shown early signs of promise. The meeting with the MHRA is very encouraging and allows us confidently to continue the development of EG013 through the pre-clinical stage to a Phase I human study." 

Dr Nigel Parker, CEO of Ark, added: "We are very pleased to receive this input from the MHRA. Their support is further validation of our gene-based medicine technology and expertise and we look forward to progressing this programme with our collaborators."

About 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 six marketed devices, Kerraboot®, Kerraped®, Flaminal®, Neuropad®, KerraMax®  and Kerraglove®, three further lead pharmaceutical products in late stage clinical development: Cerepro®, Vitor™, and Trinam® and two in Phase I/IIa trials, EG011 and EG016 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 Ylä-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. 

Ark's shares were first listed on the London Stock Exchange in March 2004 (AKT.L).
