The Company announces that following the Extraordinary General Meeting, it has been informed by Yamanouchi Pharmaceutical Co. Ltd ('Yamanouchi') that as a result of a portfolio review arising out of the merger of Yamanouchi with Fujisawa Pharmaceutical Co, it is likely that Yamanouchi will terminate the licensing agreement, covering Japan and some other Asian countries, in connection with PYM50028 (CoganeTM), Phytopharm's candidate product for the treatment of Alzheimer's disease. The decision has not yet been finally ratified and Phytopharm has not yet received formal notice of termination. Yamanouchi has acknowledged that safety data in relation to 60 patients treated with PYM50028 has fulfilled the criteria set out in the licensing agreement between Phytopharm and Yamanouchi. Furthermore, Yamanouchi has stated that it will make a milestone payment of £4.0 million to Phytopharm. In the light of this change to the Company's position, the Board of Phytopharm and its Sponsors, Stock Brokers and Underwriter have mutually agreed to terminate the proposed fund raising. The Board notes that Yamanouchi has stated that it will make a milestone payment of £4.0 million to Phytopharm and the Board is considering its position with regard to any future fund raising.
