Filter by:This study will evaluate the immunogenicity and tolerability of V503 (a multivalent human papillomavirus [HPV] L1 virus-like particle [VLP] vaccine) in preadolescent and adolescent participants between 9 and 15 years old and demonstrate the consistency of the manufactured vaccine through assessment of 3 different final manufacturing process lots of V503. The primary hypotheses are as follows: 1. The 9-valent HPV L1 VLP vaccine when administered to preadolescent and adolescent boys and girls 9 to 15 years of age and young women 16 to 26 years of age is generally well-tolerated. 2. 9-valent HPV L1 VLP vaccine induces non-inferior immune responses in preadolescent and adolescent girls 9 to 15 years of age who are seronegative at Day 1 to the relevant HPV type compared to young women 16 to 26 years of age who are seronegative at Day 1 and polymerase chain reaction (PCR)-negative Day 1 through Month 7 to the relevant HPV type, as measured by anti-HPV 6, 11, 16, 18, 31, 33, 45, 52, and 58 geometric mean titers (GMTs) at 4 weeks post-dose 3. 3. The 9-valent HPV L1 VLP vaccine induces non-inferior immune responses in preadolescent and adolescent boys 9 to 15 years of age who are seronegative at Day 1 to the relevant HPV type compared to young women 16 to 26 years of age who are seronegative at Day 1 and PCR-negative Day 1 through Month 7 to the relevant HPV type, as measured by anti-HPV 6, 11, 16, 18, 31, 33, 45, 52, and 58 GMTs at 4 weeks post-dose 3. 4. Three separate final manufacturing process (FMP) lots of the 9-valent HPV L1 VLP vaccine induce similar immune responses, as measured by anti-HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58 GMTs at 4 weeks post-dose 3.
1. Hypothesis: If high risk genotypes of human papillomavirus (HPV) is the cause of cervical cancer worldwide, the genotypes associated with cervical cancer in Venezuela would be the same types found in other countries. 2. Objectives: Primary objective: The objective of this investigation is to determine the presence and genotypes of HVP infection in cervical intraepithelial neoplasia grade 2/3 (CIN 2/3), and Stage I cervical epidermoid carcinoma and cervical adenocarcinoma. Specific objectives: To establish the presence of HPV in cervical cancer patients in Venezuela by geographic distribution. To establish which HPV types are linked with cervical cancer in Venezuela by geographic distribution.
The purpose of this study is to determine the prevalence and type distribution of genital human papillomavirus (HPV) infection in Tanzanian men.
The objectives are to evaluate the effectiveness of treatment of cervical intraepithelial neoplasia (CIN) by loop electrosurgical excision procedure using persistence of human papillomavirus (HPV) as outcome, and to perform a long-term follow-up on the ability of HPV testing, as compared to cytology, to predict recurrence of high-grade CIN.
This extension study is conducted to assess the efficacy of the GSK 580299 vaccine against cervical intraepithelial neoplasia (CIN) lesions, cervical cancer and cytological abnormalities associated with human papillomavirus (HPV)-16 and/or HPV-18 or other oncogenic HPV types for an additional two years. All subjects who participated in the primary vaccination study NCT00316693 and who confirmed their interest in participating in a long term follow up study will therefore be invited to be followed for up to 48 months after administration of the first dose of vaccine. In addition, safety and persistence of the humoral immune response will be evaluated in this study. This protocol posting deals with objectives & outcome measures of the extension phase at Months 36 and 48. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT number = NCT00316693).
The primary objectives of this study are to determine the acceptance and potential for the effective use of HPV vaccine in the standard and a modified schedule in female sex workers. Secondary objectives include ascertaining the prevalence of HPV types among female sex workers by age and sexual experience.
RATIONALE: Gathering information about human papilloma virus (HPV) infection in HIV-positive men who have sex with men may help doctors learn more about the disease. PURPOSE: This clinical trial is studying HPV infection in HIV-positive Indian men who have sex with men.
RATIONALE: Gathering information about human papillomavirus infection of the mouth in young men may help doctors learn more about risk factors for oropharyngeal cancer. PURPOSE: This research study is assessing human papillomavirus infection of the mouth in young men and risk factors for oropharyngeal cancer.
This research trial studies carbonic anhydrase 9 (CA-IX), p16, proliferative markers, and human papilloma virus (HPV) in diagnosing cervical lesions in patients with abnormal cervical cells. Studying biomarkers in abnormal cervical cells may improve the ability to find cervical lesions and plan effective treatment.
This research trial studies extended follow up of young women in Costa Rica who received vaccine for human papillomavirus types 16 and 18 and unvaccinated controls. Collecting information from young women in Costa Rica who have received vaccine for human papillomavirus types 16 and 18 and a new group of unvaccinated controls enrolled for the follow-up period, may help doctors learn more about the risks and benefits of prophylactic human papillomavirus vaccine.
