Key information

About this study

In order to confirm the safety, 80 healthy adult were enrolled first. Eligible subjects were randomized into 1:1 ratio to receive three doses of either test vaccine (NPB615) or comparator vaccine (Gardasil). The safety of the test vaccine (NBP615) was confirmed by 2nd vaccination in adult subjects. After that, enrolment of 120 adolescent subjects proceeded. Eligible subjects who previously agreed to participate in the study were screened and only those subjects who met the inclusion/exclusion criteria were randomized in to 1:1 to receive two doses of test vaccine (NBP615) or comparator (Gardasil pre-filled syringe). 0.5 ml Intramuscular injection at were given at each vaccination and two blood sample, pre vaccine and post vaccine 4 weeks after completion of vaccine were collected to assess the immunogenicity of NBP615 and Gardasil, comparator vaccine. Solicited adverse events occurred up to 7 days after each dose of the investigational product were collected in the diary card. Unsolicited adverse events occurred up to 28 days after each dose of the investigational product were collated in the diary card. Serious adverse events were collected during the entire study period. In addition to this safety data was collected through the study period by active contact with the study participants by doing home visit or by telephone contact.
