Daiichi Sankyo Announces Cooperative Sales Agreement for the Recombinant Adsorbed Hepatitis B Vaccine "Bimmugen®"

Tokyo, Japan (August 28, 2014) - Daiichi Sankyo Company, Limited (hereafter, Daiichi Sankyo) announced today that it has signed a cooperative sales agreement with The Chemo-Sero-Therapeutic Research Institute (hereafter, "Kaketsuken") on August 22 for its recombinant adsorbed hepatitis B vaccine (yeast-derived), Bimmugen® (here after, "the vaccine").

Kaketsuken originally obtained approval for the vaccine in 1988 as a genetic recombinant drug manufactured using proprietary Japanese technology. The main aim of the vaccine is prophylaxis against hepatitis B, and to date the vaccine has been administered to over 4 million people in Japan.

This agreement grants Daiichi Sankyo the right to sell the vaccine in Japan, which it hopes will aid prevention of hepatitis B, as well as further raise the company's presence in the Japanese vaccine market.
