Influenza :: Novartis cell culture-derived influenza vaccine well tolerated and efficacious

Novartis (NYSE: NVS) announced today results of pivotal Phase III clinical trial data for its innovative cell culture-derived influenza vaccine demonstrating that it is highly capable of producing an immune response (“immunogenic”), one at least as strong as the traditional egg-derived influenza vaccine Aggripal? for each of the three influenza strains studied.

The findings, which were presented at the Second International Conference on Influenza Vaccines for the World (IVW 2006), also showed the cell culture-derived influenza vaccine was well tolerated and no difference in the safety profile was observed compared to traditional egg-based vaccines.

“Novartis is committed to bring cell culture-derived influenza vaccine to market,” said J?rg Reinhardt, CEO of Novartis Vaccines and Diagnostic. “These data support this effort and help to further establish Novartis as a leader in bringing this innovative vaccine technology to the next level.”

Cell-culture based influenza vaccines promise many advantages over egg-based production, including greater reliability and reduced production lead time that could be critical in a pandemic. Novartis submitted its cell culture-derived influenza vaccine for European Union approval in June 2006, while US clinical studies began in 2005 and are ongoing.

This cell culture-derived influenza vaccine technology utilizes an alternative approach to vaccine production by which influenza virus is grown in readily available mammalian cell lines (Madin-Darby Canine Kidney, or MDCK cells). Conventional influenza vaccine production utilizes chicken eggs as hosts for virus replication followed by virus purification.

About the study results
A large-scale Phase III study was conducted in Poland during the 2004-2005 influenza season. In this observer-blind, multi-center program, 1,300 adults (age 18-60) and 1,354 elderly (age 60 or older) were randomized to receive the new Novartis cell culture-derived influenza vaccine or an egg-derived, conventional vaccine (Agrippal). Each subject received a single 0.5 ml intramuscular injection. The ability for the vaccine to provoke an immune response (immunogenicity) against the influenza viruses was evaluated according to the European Union’s Committee for Medicinal Products Human Use (CHMP) criteria.

The cell culture vaccine met all three of the CHMP full criteria, and showed no difference between the cell culture-derived influenza vaccine and the conventional egg-based vaccine. The incidences of local and systemic adverse events were similar between the two vaccines in both adult and elderly subjects, indicating that the cell culture-derived vaccine was as well tolerated as the egg-derived vaccine.

About influenza
Influenza is a contagious, potentially serious respiratory illness caused by influenza viruses that attack the upper respiratory tract. It can cause mild to severe illness, and at times can lead to death. Influenza viruses easily spread from person to person in respiratory droplets created by coughing and sneezing. Although difficult to assess, annual influenza epidemics are thought to result in between three and five million cases of severe illness and between 250,000 and 500,000 deaths annually around the world.
