Schering-Plough announces collaboration with World Health Organization

Fred Hassan, chairman and CEO, said, "This project demonstrates Schering-Plough's strong commitment to innovation and to providing access to medicines. The avian influenza virus is already affecting several developing countries, making pandemic influenza vaccine preparedness a global health priority. Our collaboration with the WHO is most important because it is aimed at allowing many developing countries to gain access to proven influenza vaccine manufacturing platforms."

Under the agreement, which was signed recently at WHO headquarters in Geneva, Nobilon has granted WHO a non-exclusive license to develop, register, manufacture, use and sell seasonal and pandemic live, attenuated, influenza vaccines (LAIV), produced on embryonated chicken eggs. WHO will be permitted to grant a sub-license to vaccine manufacturers in developing countries working within the framework of the WHO Global Vaccine Action Plan. Vaccine manufacturers to whom a sub-license will be granted will be able to provide vaccines to the public sector of developing countries royalty-free.

Egg-based LAIV technology is specifically considered attractive for this purpose because the manufacturing technology process is easier to transfer, capital investment is lower and yields are higher, as compared to inactivated influenza vaccines.

The WHO Global Vaccine Action Plan seeks to expand influenza vaccine manufacturing capacity in developing countries and enhance the global supply for pandemic vaccines.

About Live Attenuated Influenza Vaccine (LAIV)
Nobilon acquired in 2004 the majority of rights to develop, commercialize and manufacture the Live Attenuated Influenza Vaccines (LAIV), both egg- and cell culture-based, from Australian company BioDiem, which had acquired these rights from the Institute of Experimental Medicine in St. Petersburg, Russian Federation. The LAIV may offer several improvements over current vaccines such as single-dose intranasal spray delivery, improved convenience and earlier and broader protection, which is of particular interest in a pandemic situation. Nobilon is developing a cell culture-based LAIV for seasonal influenza and is currently preparing for the 'first-in-human' study with LAIV for seasonal influenza.
