Ark Therapeutics Group plc("Ark" or the "Company") today announces that it has received positive feedback from the EMEA Gene Therapy Working Party (GTWP) regarding the pre-clinical toxicology and Phase 1 trial requirements for EG013, an adenovirally mediated VEGF based product, being developed for foetal growth restriction. The GTWP commented on the nature of the pre-clinical models, toxicology and the design of a Phase 1 trial.

The GTWP clarified the indication (severe foetal growth restriction), the method of administration (imaging guided catheter introduced via the femoral vessels in the groin) and commented on a programme of in vivo model and in vitro tissue work incorporating biodistribution and germ line integration. The GTWP rapporteur did not have major concerns with regard to the Phase 1 trial proposed by Ark , with neonatal outcome being an efficacy endpoint.

Foetal growth restriction is an often terminal condition in which insufficient blood supply via 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 about 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 is maintained for 50 days. Preliminary biodistribution results using immuno-histochemical techniques have indicated that there is no transfer of the gene into the foetus in the first days. If 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 is currently undertaking work to select the optimal VEGF gene variant for EG013 and expects to complete this in early Q4 prior to commencing final pre-clinical work.

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.

Commenting on the meeting with the GTWP, 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 response from the GTWP is encouraging and the guidance they have given us will be very helpful in finalising the pre-clinical development and Phase I human study."

Nigel Parker CEO at Ark added: "We are very pleased to receive this input from the GTWP. 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 four marketed devices, Kerraboot®, Kerraped®, Flaminal® and Neuropad®, and three further lead pharmaceutical products in late stage clinical development: Cerepro®, Vitor™, and Trinam®, 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. www.arktherapeutics.com

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