NCT04982614

Brief Summary

This is a multi-site, open-label non-inferiority study of the 9vHPV vaccine among a population of children, adolescents and young women living with HIV in Eswatini. This protocol seeks to assess immunogenicity of a two-dose 9vHPV vaccine regimen among girls and boys (9-14 years) and young women (15-26 years) living with HIV on antiretroviral therapy versus a three-dose 9vHPV vaccine regimen among HIV uninfected young women (15-26 years) in Eswatini. The secondary objectives include examining the safety profiles of the two-dose 9vHPV regimen in those living with HIV and the three-dose 9vHPV regimen in HIV-uninfected young women, as well as measuring the completion of the vaccination series among those living with HIV and those who are not infected with HIV.

Outcome Measures

Primary Outcomes (2)

  • Anti-HPV geometric mean antibody titers

    Serum antibodies against HPV antigens (IgG, IFNg, TNF, IL2, CXCL10, granzyme, perforin, PTX3). Geometric mean titers will be summarized by treatment group, and the ratios of mean GMTs between treatment and control and their 95% confidence intervals calculated around point estimates.

    Month 7 (4 weeks post Month 6 vaccine dose)

  • Number of seroconversions

    Number of participants who seroconvert, defined as having no HPV antibodies pre-vaccination, but detectable HPV antibodies at 4 weeks post month 6 vaccine dose

    Month 7 (4 weeks post Month 6 vaccine dose)

Secondary Outcomes (2)

  • Number of participants with serious adverse events (SAE)

    Up to 6 months

  • Number of participants completing vaccination series

    Up to 6 months

Study Arms (2)

2-dose regimen group

EXPERIMENTAL

Boys and girls (aged 9-14 years) and young women (aged 15-26 years) living with HIV will receive a two-dose regimen of the HPV vaccine at baseline (Month 0) and Month 6.

Biological: Gardasil ® 9

3-dose regimen group (SOC)

ACTIVE COMPARATOR

HIV-uninfected young women (aged 15-26 years) will receive the standard of care three-dose regimen of the HPV vaccine at baseline (Month 0), Month 2 and Month 6.

Biological: Gardasil ® 9

Interventions

Gardasil ® 9BIOLOGICAL

GARDASIL 9 is a vaccine indicated in girls and women 9 through 45 years of age for the prevention of the following diseases: Cervical, vulvar, vaginal, and anal cancer, and Genital warts (condyloma acuminata) caused by Human Papillomavirus (HPV). 0.5-mL suspension for intramuscular injection as a single-dose vial and prefilled syringe at the following regimen/schedule: 9 through 14 years - 2-dose at 0, 6 to 12 months OR 3-dose at 0, 2, 6 months 15 through 45 years - 3-dose at 0, 2, 6 months

Also known as: Human Papillomavirus 9-valent Vaccine, Recombinant, 9vHPV vaccine
