NCT04199689
The purpose of this study is to evaluate the efficacy, immunogenicity and safety of the 9vHPV vaccine in men 20 to 45 years of age. The primary hypothesis tested after the primary database lock is that administration of a 3-dose regimen of 9vHPV vaccine will reduce the incidence of human papillomavirus (HPV) 16/18/31/33/45/52/58-related oral persistent infection (6 months or longer) compared with placebo. There will also be an Extension Study to offer an opportunity to complete the 3 dose regimen of 9vHPV vaccine for participants who received placebo in the Base Study, or received less than 3 doses of 9vHPV vaccine in the Base Study.
NCT06854354
Randomized clinical trial with two groups, with a test-retest model, with single-blind approach, using a probabilistic sampling and the population was mothers of girls aged 9 to 12 years from a public elementary school in the state of Puebla. The objective was to determine the effect of the intervention "Vaccine for HPV Prevention" aimed at the acceptance of the HPV vaccine in mothers of girls aged 9 to 12 years old in the urban area of the State of Puebla.
NCT03610581
The main purpose of this study is to assess safety and reactogenicity of the 3 vaccine regimens.
NCT06700941
The goal of this observational study is to assess the impact of HPV vaccination on cervical lesions and genital warts in Colombian birth cohorts. The study examines the trends in healthcare services usage related to these conditions, particularly among vaccinated and unvaccinated populations. The main questions it aims to answer are: Have health services usage rates for preneoplastic cervical lesions and genital warts decreased among cohorts of girls eligible for HPV vaccination after the vaccine's introduction? Have there been reductions in health services usage for genital warts among male cohorts of the same birth years as vaccinated girls? Researchers will compare health services usage trends between vaccinated and unvaccinated populations, as well as geographical areas with differing levels of HPV vaccination coverage, to evaluate the impact of the HPV vaccination program. Participants will not be directly involved, as this is a retrospective analysis of existing healthcare records from various national databases, assessing the frequency of healthcare services related to preneoplastic lesions and genital warts, as well as vaccination coverage at national, departmental, and municipal levels.
NCT04910438
The DepIST-H study, funded by the French AIDS and Hepatitis Research Agency (ANRS), is to estimate prevalence (the number of cases over a given period of time) and incidence (the number of new cases over a given period of time) of anal lesions (condylomas, dysplasia, cancers) by HIV status among MSM in Lomé, Togo
NCT02897232
This is a minimal risk, anonymous, convenience sample, social behavioral study using qualitative descriptive survey methods. It is to ascertain community member, physician, resident and medical student perspectives regarding Human Papillomavirus (HPV) infection, associated diseases and to identify barriers which prevent these groups from ensuring that males 9-26 receive the three-shot vaccine series to prevent HPV infection. The research is focused on these questions: Do community members understand the ease of transmission of the HPV virus in males 9-26? Do community members, physicians, residents and medical students have knowledge of the associated diseases that may occur with the HPV virus infection in males age 9-26? Do community members, physicians, residents and medical students know the ages in which males should receive the HPV vaccine three-shot series? What barriers prevent community members and physicians, residents and medical students from ensuring that males 9-26 receive the three-shot vaccine series to prevent HPV infection?
NCT03546842
This study will evaluate the safety and immunogenicity of V503 (GARDASIL™9, 9vHPV vaccine) administered to 9- to 26-year-old females and males in Vietnam. The study hypothesis states that V503 induces acceptable anti-human papillomavirus (HPV) 6, 11, 16, 18, 31, 33, 45, 52, and 58 seroconversion at 4 weeks postdose 3.
NCT03548740
Since other genital infections enhance HIV susceptibility by inducing inflammation, the investigators study the relationship between the vaginal microbiota composition and the risk of HPV infection, cervical cytological abnormalities.
NCT02346227
1. Introduction Cervical cancer (CC) is a major public health problem in Low-income countries (LICs), particularly in the Democratic Republic of the Congo (DRC), where the estimated number of cases is 3839 per year. (WHO, 2010). Persistent infection with Human Papillomavirus (HPV) is recognized as the necessary cause for the development of CC. Thus, CC is a disease that is easily preventable primarily by vaccination against HPV and secondarily through screening and treatment of precancerous lesions of the cervix. In LICs, the high incidence of CC is due to both high rates of infection with HPV, a failure to initiate and sustain effective screening programs based on cytology and the non-availability of vaccination against HPV. These situations highlight the need to implement simple and inexpensive screening and treatment methods suitable for LICs. These methods include screening by visual inspection of the cervix after application of acetic acid (VIA) and treatment with a topical antiviral drug (AV2). 2. Aims This study aims to: * Evaluate the clinical efficacy of AV2 as a treatment for HPV-associated lesions of the uterine cervix; * Identify HPV genotypes found in Kinshasa; * Determine the cost-effectiveness of an algorithm combining screening by VIA and AV2 and that combining VIA and cryotherapy treatment; 3. Methods After basic training of local health workers on VIA, on collection of cervical samples for HPV testing (quantitative Polymerase Chain reaction, qPCR) and liquid-based cytology (LBC) and on application of AV2, a screening and treatment program will be offered to women aged 25 and older who will give their informed consent. All women with lesions on VIA will be randomized into one of two groups to receive either treatment by AV2 or placebo. All women with lesions on VIA will be monitored and reviewed after two months and after six months for repeat tests (VIA and LBC for lesions, qPCR for viral load, conversion and reinfection rates).
NCT02535104
Ranpirnase in topical formulation is an antiviral drug being evaluated for the topical treatment of anogenital warts. The aims of this study is to evaluate the efficacy and safety of a topical formulation of ranpirnase in subjects with genital warts.
NCT00188292
Cancer of the anus occurs at very high rates in young men with HIV and is caused by a virus called human papillomavirus (HPV). Anal cancer has increased during the HIV epidemic despite effective therapies for HIV. Unfortunately, anal cancer presents at a late stage because there is no screening program to find it at an early stage. Rates of other cancers such as cervical cancer have been reduced through the use of Pap smears. The researchers' plan is to do the same type of screening for anal cancer as has been done for cervical cancer. If abnormalities are found then treatment can be started. The researchers hope that this approach will help to prevent anal cancer. Testing for HPV will also be done to see if this helps to detect early cancer and to see how accurate different tests, pathologists and clinical examiners are at detecting and agreeing on any abnormalities. The main outcome is the presence of any pre-cancerous or early cancer changes as determined by high resolution anoscopy (HRA). HRA involves looking through a microscope into the anus and this allows very tiny changes to be identified. Pieces of tissue can then be taken to make a definite diagnosis.
