Japanese regulator approves manufacture and marketing of Daiichi Sankyo/Biota's flu drug Inavir

14 September 2010

Japan’s third-largest drugmaker Daiichi Sankyo (TSE: 4568) says it has received approval in Japan to manufacture and market Inavir (laninamivir octanoate) dry powder Inhaler 20mg, for the treatment of influenza.

The news saw shares of partner Biota Holdings, headquartered in Australia, surge 17.4% to A$1.045 on Monday, in anticipation of royalty payments as well as possible sales milestones.

Inavir is a long-acting neuraminidase inhibitor that Daiichi Sankyo developed for the Japanese market. Inavir directly delivers the drug to the infected airways of influenza patients, and a single inhaled dose has proven to be as effective as a five-day course of oseltamivir for treatment of influenza.
