GlaxoSmithKline on Monday announced that the European Commission has approved the company's experimental human papillomavirus vaccine Cervarix for sale and marketing in the European Union, Reuters reports. Cervarix has been shown to be 100% effective in preventing infection with HPV strains 16 and 18, which together cause about 70% of cervical cancer cases.
According to a recent study, Cervarix was 90.4% effective in preventing lesions caused by HPV strains 16 and 18, based on an analysis that only required detection of the virus in the lesions. However, researchers found most of the lesions contained multiple HPV strains known to cause cancer, and GSK said the data showed Cervarix was 100% effective in preventing lesions caused by strains 16 and 18.
According to the study, the vaccine also provided significant protection against HPV strains 31, 45 and 52, which together account for about 12% of cervical cancer cases.
GSK declined to comment on how much the company will charge for Cervarix or whether the European price would be above or below that in Australia, where the vaccine received regulatory approval in May. The vaccine is not likely to go on sale in the U.S. before 2008, Reuters reports. The company said a decision on its FDA application for Cervarix's approval in the U.S. will be given in January 2008.
"The decision (by the European Commission) to approve Cervarix for the European Union represents a great step forward for European women," GSK CEO J.P. Garnier said in a statement. He added, "Physicians across Europe will now have access to this important vaccine to help protect women against cervical cancer, the second most common cancer in women"
