Dainippon Pharmaceutical is shortly to start clinical development of its anti-epileptic zonisamide in the USA, according to Pharma Japan. The product was first launched in Japan, in May 1989, under the trade name Excegran. Zonisamide is indicated in Japan for the treatment of incurable epileptic convulsions.
US testing will be carried out by a local clinical trials contractor, the Institute for Biological Research and Development, which is based in Irvine, California. The IBRD was acquired by the US subsidiary of Kuraya, one of Japan's leading pharmaceutical wholesalers, in 1990.
