L'essai clinique NCT00923702 est conçu pour étudier la prevention de Cancer du col de l'utérus, Cervical Precancerous Lesions. Il s'agit d'un essai interventionnel en Phase IV. Son statut actuel est : actif, pas en recrutement. L'essai a débuté le 1 septembre 2009 et vise à recruter 22 729 participants. Dirigé par Partha Basu, l'essai devrait être terminé d'ici le 1 juillet 2026. Les données du site ClinicalTrials.gov ont été mises à jour pour la dernière fois le 28 septembre 2023.
Résumé succinct
The primary study hypothesis wasthat a two-dose human papillomavirus (HPV) vaccine regimen would offer similar immunogenicity and protection as that of a three-dose regimen to girls against persistent HPV infection and cervical neoplasia caused by HPV types included in the vaccine. The Government of India stopped vaccination in all the HPV vaccine trials in the country in April 2010 due to reasons not related to this study.
Description détaillée
The suspension of vaccination resulted in girls receiving 3 doses (days 1, 60 and ≥180), receiving 2 doses (days 1 and ≥180), receiving 2 doses at days 1 and 60 due to incomplete treatment ("by default"), and receiving one dose by default. A first age and site-matched cohort of unvaccinated married women was recruited, starting in May 2012 to serve as the unvaccinated control group of women for the analysis of HPV incidence and persistence outcomes. A second age and site-matched (age and site matched to the vaccinated women undergoing screening) cohort of unvaccinated married women is being recruited starting in June 2017 and is to be used in addition to the first unvaccinated cohort for the assessment of the cervical neoplasia outcome.

Critères d'évaluationDescription de critèresPériode
Median Florescent Intensities (MFI) of the Total Antibodies to Vaccine-included HPV Types (16/18/6/11) at Different Time Points
Samples were treated with EDTA and analysed with Luminex (Austin, TX, USA) based multiplex serology to assess the concentration of binding antibodies against the major capsid protein L1 as mean median fluorescence intensity (MFI). MFI values as a measure of antibody concentration quantified by use of HPV multiplex serology are directly comparable with optical densities measured with ELISA.
Month 7 (for 3-dose and 2-dose groups), 12 (for 2 doses by default and single-dose groups), 18, 36, 48
Frequency of Persistent HPV 16/18/6/11 Infection.
The first cervical cell samples were collected from women 18 months after married or 6 months after the first delivery. After that, 3 extra annual collections were obtained. The HPV genotyping method involved HPV-type-specific E7 PCR bead-based multiplex genotyping. The multiplex HPV-type-specific E7 PCR uses HPV type-specific primers targeting the E7 region for the detection of 19 high-risk or probable high-risk HPV types (16, 18, 26, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68a, 68b, 70, 73, and 82), and two low-risk HPV types (6 and 11), with detection limits ranging from ten to 1000 copies of the viral genome.
