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® 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 both 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, where 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).
