Sanofi Pasteur MSD has announced that the European Commission has granted marketing authorization for its quadrivalent Human Papillomavirus (HPV) vaccine, Gardasil®, for a 2-dose schedule at 0 and 6 months in children aged from 9 to 13 years.
"We are delighted to be able to offer this new, 2-dose schedule. It is based on data showing that 2 doses elicited a immune response in adolescents comparable to that of 3 doses in young women to the four HPV types - 6, 11, 16 and 18 - included in Gardasil®", said Dr Stephen Lockhart Vice President, Development of Sanofi Pasteur MSD. "These results are sustained 3 years after vaccination, which indicates that a 2 dose 0-6 month schedule of Gardasil®, is able to induce high antibody levels for protection against HPV-diseases." concluded Dr Lockhart.
The approval of this new schedule for Gardasil® follows the positive opinion from the European Medicines Agency (EMA) granted in February, based on a Canadian study performed by Dobson et al. It demonstrates that the 2-dose 0, 6 month schedule in 9-13 year old girls elicited an immune response comparable/non-inferior to that of 3 doses in the 16-26 year old women, the population where quadrivalent vaccine efficacy has been shown. These results were sustained at 36 months of follow-up. 1*
Adolescents aged 14 years and above should still receive 3 doses at 0, 2 and 6 months. For children aged 9 to 13 years, the 3-dose schedule can alternatively be given, in accordance with national recommendations and immunisation programmes currently in use. >sup>2
Data recently published from a study in Australia showed the rapid impact of Gardasil® on disease in the real-world setting, with a strong reduction in high grade pre-cancerous cervical lesions in young women at population level. 3 Australian national vaccination programmes with Gardasil® also resulted in the near disappearance of genital warts in Melbourne area in women under 21 years of age. 4
To date, more than 29 Million doses of Gardasil® have been distributed in Western Europe, helping to protect futures of millions of adolescents. 5
Gardasil® is indicated in girls and boys from 9 years of age for the prevention of premalignant genital lesions (cervical, vulvar and vaginal) and cervical cancer causally related to certain oncogenic Human Papillomavirus (HPV) types as well as genital warts (condyloma acuminata) causally related to specific HPV types.
Gardasil® is a quadrivalent vaccine for protection against cancer of the cervix and other genital diseases caused by the human papillomavirus types 6, 11, 16 and 18: precancerous lesions of the cervix (CIN2/3), precancerous lesions of the vulva (VIN2/3) and vaginal (VaIN2/3) and genital warts (condyloma acuminata).
Data published since Gardasil® came on the market have confirmed the positive impact of this vaccine on the prevention of genital diseases caused by human papillomavirus types 6, 11, 16 and 18.
Launched in 2006 and manufactured by Merck, it is the most widely used HPV vaccine worldwide with approximately 144 million doses distributed globally to date.
