Filter by:This project will compare the rate of regression of minimally abnormal Pap smears to normal in women who receive Gardasil to a historical control group. Research hypothesis: Women with low grade cervical dysplasia on Papanicolaou (Pap) smear that receive Gardasil vaccination will revert to a normal within one year at a rate 33% higher than historical controls that did not receive Gardasil vaccination.
This is a China registration study. A randomized, double-blind, placebo-controlled immunogenicity and safety study in Chinese female participants aged 9 to 45 years and male participants aged 9 to 15 years. Approximately 600 participants will be randomized in a 1:1 ratio to receive either vaccine or aluminum-containing placebo. Each participant received one injection at each visit at Day 1, Month 2, and Month 6. Vaccine or placebo was given as a 0.5-mL intramuscular injection. Serum will be collected from all participants to evaluate immune response against anti-Human Papillomavirus (HPV) 6/11/16/18 with Luminex Assay. At Month 2, Month 6, Month 7, subjects will be evaluated for any new medical condition or health concerns and Serious Adverse Experiences throughout the study. The primary objective is to evaluate the vaccine-induced serum anti-HPV 6, 11, 16 and 18 antibody titers following 3-dose regimen of Gardasil® compared with placebo.
The purpose of this study is to determine risk factors for HPV infections in 25 to 65 year old women who report having used internet dating websites in the past year.
Human papillomavirus (HPV)-infection belong to the most common sexually transmitted diseases worldwide. HIV-infected men having sex with men /MSM) are strongly associated with a higher prevalence of genitoanal HPV-infection, and perianal HPV-infections have been detected in up to 90% of HIV-positive men. The data concerning the incidence of oral HPV-infection in HIV-positive men, especially in the era of highly antiretroviral therapy, are conflicting. Thus, this prospective study mainly focuses on the incidence and prevalence of oral HPV-infection, spectrum of HPV-types, and oral high-risk HPV viral load in HIV-positive men.
The purpose of this study is to evaluate the safety and tolerability of the Quadrivalent Human Papilloma Virus (HPV) vaccine in healthy females 9 to 15 years of age in India. Quadrivalent HPV Vaccine is composed of L1 virus-like particles (VLPs) from HPV types 6, 11, 16, and 18.
Human papillomavirus (HPV)-infection belongs to the most common sexually transmitted diseases worldwide. HIV-infected men having sex with men (MSM) are strongly associated with a higher prevalence of genital HPV-infection, a higher incidence of anal intraepithelial neoplasia (AIN), and, consecutively, an increased risk for anal cancer. Since the introduction of highly active antiretroviral therapy (HAART), the incidence of several viral-associated neoplasias has significantly fallen in HIV-infected individuals. At the beginning of the era of HAART, a justified hope existed that genitoanal HPV-related neoplasias would also decrease based on the success of HAART-induced immune restoration. However, HAART seems to have only a small impact on the natural history of AIN as observed in a cohort of HIV-positive MSM before and after the initiation of HAART. As AIN and cancer precursor lesions of the cervix, cervical intraepithelial neoplasia, share distinct clinical similarities, cytologic smear testing for AIN has been recommended to detect and treat early lesions. Thus, this prospective study mainly focuses on the predictive value of HPV-DNA load for the development and clinical progression of AIN in HIV-infected MSM. Moreover, the course of HPV viral load under therapy for anal intraepithelial neoplasia, e.g. topical treatment with imiquimod, will be evaluated. Additionally, immunohistochemical determination of several proliferative biomarkers, as well as cytokines, will be performed.
This study was conducted in 2 parts. Part A was a randomized, double-blind, placebo-controlled, multicenter, sequential dose-escalating evaluation. Part B was a randomized, double-blind (operating under in-house blinding procedures), placebo-controlled, multicenter, dose-ranging study.
This protocol posting deals with objectives & outcome measures of the extension phase up to Month 48. The objective of the extension study is to evaluate the long-term immunogenicity of the HPV 16/18 L1 VLP AS04 vaccine (for all subjects in the HPV Vaccine Group) by enzyme-linked immunosorbent assay (ELISA). The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT00196924). The long-term follow-up study will be blinded until the primary study is unblinded and will be open for all visits subsequent to unblinding of primary study HPV-013 (NCT00196924). During the open phase, only subjects who received the HPV-16/18 VLP/AS04 vaccine during the primary study will continue their participation in the follow-up study until Month 48. Subjects in the Control group (Havrix®) will attend one further visit as their last study visit. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
The purpose of this study was to evaluate efficacy of 851B gel over a range of concentrations and dosing regimens on high-risk cervical human papillomavirus infection in women.
This randomized phase II trial is studying green tea extract to see how well it works compared to a placebo in preventing cervical cancer in patients with human papillomavirus and low-grade cervical intraepithelial neoplasia. Chemoprevention is the use of certain substances to keep cancer from forming, growing, or coming back. The use of green tea extract may stop cervical cancer from forming in patients with human papillomavirus and low-grade cervical intraepithelial neoplasia. It is not yet known whether green tea extract is more effective than a placebo in preventing cervical cancer in patients with human papillomavirus and low-grade cervical intraepithelial neoplasia.
