LONDON and RESEARCH TRIANGLE PARK, N.C., May 1 /PRNewswire-FirstCall/ -- GlaxoSmithKline (NYSE: GSK) is committed to supporting governments and health authorities around the world to respond to the emergence of the new influenza A (H1N1) strain.
The company has developed a number of potential interventions which it believes may be of value in efforts to reduce the impact and spread of this new influenza virus. These include the antiviral medicine Relenza (zanamivir) and significant vaccine capability and technology, including use of novel adjuvants.
To ensure continuity of supply and manufacture of all its critical medicines and vaccines, GSK has also invoked its own internal pandemic preparedness plan.
Relenza (zanamivir)
GSK has been working with governments to supply Relenza, for use in a pandemic situation, since the global spread of avian influenza (H5N1) which began in 2003. Relenza has typically been used to diversify and add to government stockpiles of Tamiflu (oseltamivir).
Since 2003, Relenza has been supplied to 26 governments for the purposes of pandemic stockpiling and on average the product constituted 13% of these stockpiles. Prior to the recent outbreak, the last significant order for Relenza was for 10.6 million treatment packs, which was delivered to the UK Government in April 2009.
In relation to the new influenza A (H1N1) strain, the WHO reported that the viruses obtained from the recent human cases were sensitive to oseltamivir and zanamivir but resistant to amantadine and remantadine.(1)
GSK has therefore contacted governments around the world to ascertain demand for Relenza, including those countries most affected by the virus, such as Mexico and the USA. As a result, GSK
