研究概览

简要总结

This is a phase 2, open-label study to assess the immunogenicity of the 9-valent human papillomavirus (HPV) recombinant vaccine (Gardasil9) in people born male with current or past exposure to androgen blockers or estrogen (BM-EABE). Investigators will enroll BM-EABE with HIV and HIV negative controls (BM-EABE or men who have sex with a person with a penis (MSPP)) and administer Gardasil9 at timepoints Day 0, Month 2, and Month 6. The immune response to the vaccine will be analyzed at Month 7 (1 month following the final vaccine dose).

详细描述

This will be a phase 2, open-label study to assess the humoral and cellular immune response to the FDA-approved 9-valent HPV recombinant vaccine in people born male with current or past exposure to androgen blockers or estrogen (BM-EABE). At baseline, BM-EABE with HIV, HIV negative controls (BM-EABE or men who have sex with a person with a penis (MSPP)) will provide blood samples and anal swabs for evaluation of HPV immunity, anal HPV and anal dysplasia. All participants will undergo a 3-dose vaccine series of the Gardasil vaccine (at Day 0, Month 2 and Month 6). Participants will then return one month after completion of third vaccine (Month 7) to provide repeat blood samples and anal swabs. Samples will be compared pre and post vaccination and in-between participants based on HIV and exposure to androgen blockers or estrogen (EABE).

Any participant with human papillomavirus 16 (HPV16) and/or anal dysplasia on anal cytology at any point will be referred to high-resolution anoscopy (HRA) for clinical management. Anal biopsies will be procured from different pathology laboratories - after clinical evaluation has been complete - for research analysis, including confocal microscopy. Those who had anal dysplasia at study entry will undergo repeat HRA, as clinically indicated, and will have an optional study visit following their repeat HRA to provide blood draw and anal swabs.

  • •Born Male
  • •For Test group: HIV-positive people born male with current or past exposure to androgen blockers or estrogen (BM-EABE)
  • •Living with HIV
  • •Current or past exposure to androgen blockers or estradiol
  • •For Control group: HIV-negative Control
  • •HIV negative
  • •Either: Current or past exposure to androgen blockers or estradiol; no current or past exposure to androgen blockers or estradiol AND had sex with a person with a penis in the last year

排除标准

  • •Younger than 18 years old or older than 70 years old.
  • •Self-reported or documented history of nine-valent HPV vaccine or unsure of vaccination status and born after
  • •Born female
  • •History of hypersensitivity, including severe reactions to yeast or other component of the vaccine.
  • •Any condition requiring systemic chemotherapy or immunomodulant affecting antibody responses (i.e., rituximab, ibrutinib etc.), intravenous or subcutaneous immunoglobulin supplementation, radiation therapy, or immunomodulatory treatment within the previous 6 months (presence of precancerous lesions is not exclusionary).

结局指标

主要结局

Immunogenicity of the human papillomavirus (HPV) vaccine in BM-EABE (people born male with current or past exposure to androgen blockers or estrogen (BM-EABE) with and without HIV

时间窗: 7 months post 1st vaccine dose

Proportion of BM-EABE who become seropositive or have an increase in their GMT by \>25% to at least 1 homologous HPV vaccine genotype at 1 month following the 3rd dose of the vaccine.

次要结局

  • Compare the humoral immune response to Gardasil9 between HIV positive BM-EABE and HIV negative controls(7 months post 1st vaccine dose)
  • Compare the humoral immune response to Gardasil9 between BM-EABE (regardless of HIV status) and BM without EABE (people born male without current or past exposure to androgen blockers or estrogen)(7 months post 1st vaccine dose)
  • Evaluate the systemic HPV T-cell immune response to Gardasil9 in HIV positive BM-EABE and HIV negative controls.(7 months post 1st vaccine dose)
  • Compare systemic HPV T-cell immune response to Gardasil9 between HIV positive BM-EABE and HIV negative controls.(7 months post 1st vaccine dose)
  • Compare systemic HPV T-cell immune response to Gardasil9 between BM-EABE (regardless of HIV status) and BM without EABE.(7 months post 1st vaccine dose)
  • Evaluate the impact of HPV vaccination on HIV reservoir in CD4 T cells of BM-EABE with HIV.(Before vaccination, 7 months post 1st dose)
  • Compare humoral immune response to Gardasil9 between different subset populations from PROTECT (HIV positive BM-EABE , HIV negative BM-EABE , and HIV negative MSPP), to age-matched historical controls.(7 months post 1st vaccine dose)
