Clinical Trial Summary

Human papillomavirus (HPV) is a common sexually-transmitted virus which causes infections that usually last only a few months, but sometimes can last a long time and cause cancers of the cervix, vagina, vulva, anus or oropharynx over many years among adults. This phase IIA trial studies how well does the nonavalent HPV vaccine (which can prevent nine different types of HPV) work when given in an alternative dosing schedule to heathy young research participants.


Clinical Trial Description

PRIMARY OBJECTIVES: I. To determine the persistence and stability of serologic geometric mean titer (GMT) of HPV 16/18 between 6, 12, 18, and 24 months after the prime dose and prior to the administration of the second dose. SECONDARY OBJECTIVES: I. To determine the persistence and stability of serologic GMT of HPV types 6/11/31/33/45/52/58 between 6, 12, 18, and 24 months after prime dose and prior to the administration of the second dose. II. To assess safety and reactogenicity to each vaccine dose. OUTLINE: Participants receive recombinant human papillomavirus nonavalent vaccine intramuscularly (IM) at baseline (priming injection) and at 24 and 30 months (booster injections). After completion of study, participants are followed up for 2 weeks. ;
