Trial overview

Official title: A Double-Blind, Controlled, Randomized, Phase III Study of the Efficacy of an HPV16/18 VLP Vaccine in the Prevention of Advanced Cervical Intraepithelial Neoplasia (CIN2, CIN3, Adenocarcinoma In Situ [AIS] and Invasive Cervical Cancer) Associated With HPV 16 or HPV 18 Cervical Infection in Healthy Young Adult Women in Costa Rica.
Trial description: RATIONALE: Chemoprevention is the use of certain drugs to keep cancer form forming, growing, or coming back. Vaccines may help the body build an effective immune response against human papillomavirus and may be effective in preventing cervical intraepithelial neoplasia or cervical cancer. It is not yet known whether human papillomavirus vaccine is more effective than hepatitis A vaccine in preventing cervical intraepithelial neoplasia or cervical cancer.
PURPOSE: This randomized phase III trial is studying human papillomavirus vaccine to see how well it works compared to hepatitis A vaccine in preventing cervical intraepithelial neoplasia or cervical cancer in younger healthy participants.
Primary purpose:
Prevention
Trial design:
Parallel Assignment
Masking:
Triple (Participant, Investigator, Outcomes Assessor)
Allocation:
Randomized
Primary outcomes:

Number of histopathologically confirmed Cervical Intraepithelial Neoplasia (CIN)2+ cases associated with HPV16 and/or HPV18 infection detected in the preceding cervical cytology specimen.

Timeframe: From Month 6 up to Month 48

Secondary outcomes:

Number of cervical infection with HPV16 or HPV18.

Timeframe: From Month 6 up to Month 48

Number of histopathologically confirmed CIN2+ cases associated with infection by any oncogenic HPV type

Timeframe: From Month 6 up to Month 48

Number of persistent infection (12-month definition) with human papillomavirus (HPV)-16 or HPV-18 cases

Timeframe: From Month 6 up to Month 48
