This study has been completed.

Information provided by (Responsible Party):
Merck Sharp & Dohme Corp.
ClinicalTrials.gov Identifier:
NCT00090285
First received: August 25, 2004
Last updated: April 11, 2017
Last verified: April 2017
  Purpose
This study is to evaluate an investigational vaccine with the following objectives: to demonstrate that the vaccine is well tolerated in young men; to demonstrate that the vaccine reduces incidence of external genital lesions (Condylomata acuminata [anogenital warts], penile/perianal/perineal intraepithelial neoplasia [PIN], penile, perianal, perineal cancer) in young men; to demonstrate that the vaccine reduces the incidence of anal intraepithelial neoplasia (AIN) or anal cancer in men having sex with men (MSM); and to demonstrate that the vaccine reduces incidence of Human Papilloma Virus (HPV) infection in young men.

Condition Intervention Phase
Condylomata Acuminata Biological: (Gardasil™) human papillomavirus (types 6, 11, 16, 18) recombinant vaccine Biological: Comparator: placebo (unspecified) Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Participant, Investigator
Primary Purpose: Prevention

Primary Outcome Measures:
  • Incidence of Human Papillomavirus (HPV) Related External Genital Warts, Perineal Intraepithelial Neoplasia (PIN), Penile, Perianal or Perineal Cancer [ Time Frame: Base study: through Month 36 ]
    Subjects with HPV 6/11/16/18-related external genital warts, PIN, penile, perianal or perineal cancer per 100 person-years of follow-up.

  • Number of Participants With Severe Injection Site Adverse Experiences (AEs) [ Time Frame: Base study: through Day 5 after any vaccination ]
  • Number of Participants With Vaccine-Related Serious Adverse Events (SAEs) [ Time Frame: Base study: through Month 36 ]

Secondary Outcome Measures:
  • Incidence of HPV 6/11/16/18-related Persistent Infection [ Time Frame: Base study: through Month 36 ]
    Subjects with HPV 6/11/16/18-related persistent infection per 100 person-years of follow-up.

  • Incidence of HPV 6/11/16/18-related Deoxyribonucleic Acid (DNA) Detection [ Time Frame: Base study: through Month 36 ]
    Subjects with HPV 6/11/16/18-related DNA detection per 100 person-years of follow-up.


Other Outcome Measures:
  • Substudy to Evaluate the Incidence of HPV 6/11/16/18-related Anal Intraepithelial Neoplasia (AIN) and Anal Cancer in Men Having Sex With Men (MSM) [ Time Frame: Base study: through Month 36 ]
    Participants with HPV 6/11/16/18-related AIN or anal cancer per 100 person-years of follow-up


Enrollment: 4065
Actual Study Start Date: September 24, 2004
Study Completion Date: April 3, 2017
Primary Completion Date: July 31, 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: qHPV Vaccine Biological: (Gardasil™) human papillomavirus (types 6, 11, 16, 18) recombinant vaccine
Duration of Treatment: 6 months
Other Names:
  • qHPV
  • V501
Placebo Comparator: Placebo Biological: Comparator: placebo (unspecified)
Duration of Treatment: 6 months

Detailed Description:

The base study (V501-020) encompassed Day 1 through Month 7, during which time participants received randomly assigned Gardasil™ (qHPV vaccine) or placebo at Day 1, Month 2, and Month 6. Base study follow-up continued through Month 36.

The base study was extended in protocol V501-020-10 Extension 1 (EXT1). Participants who received placebo and participants who received only 1 dose of qHPV vaccine in the base study were offered a complete 3-dose qHPV vaccine regimen (administered at EXT1 Day 1, Month 2 and Month 6). Participants who received only 2 doses of qHPV vaccine in the base study were offered a single additional dose of qHPV vaccine (administered at EXT1 Day 1). Participants were followed to EXT1 Month 7.

A second extension study, V501-020-21 (EXT2), will estimate the long-term safety and effectiveness of qHPV vaccine during a period of 10 years following initial enrollment in the base study. Subjects who received at least one dose of qHPV vaccine in either the base study or EXT1 are eligible to enroll in EXT2.
