Pilot Study to Determine the Safety and Efficacy of Gardasil Against the Human Papilloma Virus (HPV) in HIV-infected Men

Overview

This study will investigate the efficacy and safety of the quadrivalent vaccine (Gardasil) against the human papilloma virus (HPV) in HIV (human immunodeficiency virus) infected males.

Full Title of Study: “Pilot Study to Evaluate the Immunogenicity and Safety of the HPV Quadrivalent Vaccine (Gardasil) in HIV-infected Men”

Study Type

  • Study Type: Interventional
  • Study Design
    • Intervention Model: Single Group Assignment
    • Primary Purpose: Prevention
    • Masking: None (Open Label)
  • Study Primary Completion Date: June 2012

Detailed Description

This is a prospective pilot study that will attempt to enroll approximately 150-200 HIV-infected males followed regularly in the ID Primary Care Clinic at the VA Long Beach Healthcare System. All consenting patients will be given the HPV vaccine (Gardasil) in three intramuscular injections. Baseline antibody titers to HPV strains 16 and 18 will be obtained at day 0 and repeat levels will be obtained approximately 8 weeks after the completion of the vaccination series to determine whether patients without antibodies at baseline have now produced antibodies, or to determine the change in antibody levels in those patients who have evidence of antibodies prior to the first injection of the vaccine. Patients will undergo routine anal PAP smear with HPV DNA testing at baseline and another PAP smear/HPV test approximately 8 weeks after completion of the series. Patients will report any side effects of the vaccine to the PI. Patients will have blood work to monitor HIV-1 viral load and CD4 lymphocytes counts at various points during the study.

Interventions

  • Biological: Gardasil
    • Intramuscular injections of Gardasil at Day 0, Month 2 and at Month 6

Clinical Trial Outcome Measures

Primary Measures

  • Determine Geometric Mean Titers of anti-HPV 16 and anti-HPV 18 antibodies
    • Time Frame: nine months
  • Determine percentage of subjects who seroconverted or mounted a significant serologic response to each of the 2 antigens 16 and 18
    • Time Frame: 8-9 months
  • Determine how many patients, if any, develop evidence of anal HPV infection, as measured by development of a positive HPV test.
    • Time Frame: 9 months
  • Determine if vaccinations will activate the subject’s immune systems sufficiently that the HIV-1 viral load either increases from the baseline value, or becomes detectable and stays detectable after being undetectable at the baseline visit
    • Time Frame: nine months
