Active clinical trials for "Papillomavirus Infections"

The purpose of this study to evaluate the safety and immunogenicity of a 2-dose regimen of 9vHPV vaccine, where the first dose is administered concomitantly with a first dose of a 2-dose regimen of mRNA-1273 vaccine versus nonconcomitant administration of 9vHPV and mRNA-1273 vaccines in boys and girls 9 to 11 years of age.

This clinical trial compares three anal cytology collection procedures (collected at a single visit) in men who have sex with men (MSM). It also compares two different tests for human papilloma virus, the virus that causes high grade anal dysplasia, which is thought to occur before anal cancer. This study may help doctors develop better screening for high-grade anal dysplasia in MSM in order to identify those who need to return for additional screening and treatment.

Human papillomavirus (HPV) is currently one of the most common sexually transmitted infections, according to its carcinogenicity is divided into high-risk genotypes and low-risk genotypes, research has confirmed that carcinogenic HPV type continuous infection leads to a higher incidence of condyloma acuminatum and cervical cancer, while increasing the oropharyngeal cancer, vaginal cancer and other related cancer risk. Based on clinical practice, the purpose of this study was to: 1) identify the correlation between HPV integration and the outcome of disease in HSIL women. 2) To determine the prognostic value of different HPV gene integration status in HSIL women. 3) To clarify the relationship between different HPV gene integration status and diversity of vaginal flora in HSIL women.

Based on the evidence summarized in the introduction, the clinician hypothesize that the detection of the presence and expression of HPV-DNA, certain miRNAs, and a certain mutational profile in the tissues and biological fluids of these patients, may have important prognostic and diagnostic value not only in HPV-related OPSCCs but also in HPV+ occult T. Accordingly, this study aims to aim to better characterize their potential as biomarkers and to detect the possibility of their their use to implement the sensitivity and specificity of radiological methodologies (PET-CT and MRI), already in use in clinical practice, for monitoring disease progression in this specific subgroup. Finally, by using the collected material to generate organoids and Patient Derived Xenograft (PDX), the study also aims to identify possible new molecular drugs, which could solve the problem of resistance to radiochemotherapy.

A single-blind, randomized, and probiotic-treatment including adult women with vaginitis and/or HPV positive. After oral probiotics, all participants will be followd-up cervical swabs and vaginal microbiome alteration till the end of the study.

The KEN SHE Study aims to identify effective cervical cancer prevention strategies. Cervical cancer is caused by an infection with Human Papillomavirus, also called HPV. In Kenya, about 2,500 women die from this condition each year. The study is conducted by Kenya Medical Research Institute (KEMRI) sites, based in Kisumu, Thika and Nairobi and the University of Washington, Seattle, USA. The purpose of this study is to learn whether a single dose of the HPV vaccine prevents HPV infection among adolescents and young women. Using a single dose will lower the cost of providing HPV vaccination (compared to two doses) and will make it possible for more women to receive the vaccination and be protected from cervical cancer. The study will involve approximately 21 clinic visits over a period of 55 months. All visits will involve blood draws and many will involve pelvic swabs. Participants will receive an FDA-approved HPV vaccine and a meningococcal vaccine.

This study will investigate the immunogenicity and safety of the 9vHPV vaccine in healthy Chinese females 9 to 45 years of age. The study consists of Stage I (Day 1 to Month 7) and Stage II (post Month 7 to Month 60). Stage II will report the long-term immunogenicity and safety in the 9-19 year-old age group only. The dual-primary hypotheses of Stage I are that 9vHPV vaccine induces non-inferior immune responses in females 9 to 19 years of age who are seronegative at Day 1 to the relevant HPV type compared to females 20 to 26 years of age who are seronegative at Day 1 to the relevant HPV type, as measured by anti-HPV 6, 11, 16, 18, 31, 33, 45, 52, and 58 GMTs at 1 month post Dose 3, and 9vHPV vaccine induces non-inferior immune responses in females 27 to 45 years of age who are seronegative at Day 1 to the relevant HPV type compared to females 20 to 26 years of age who are seronegative at Day 1 to the relevant HPV type, as measured by the seroconversion percentages to each of HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58 at 1 month post Dose 3. (Each vaccine component will be analyzed separately.)

The goal of this study is to explore and evaluate whether a 2-dose schedule of Gardasil 9 among young and mid-adult women 16-45 years of age is generally safe and immunogenic, with an antibody response that is not inferior to that observed of a 3-dose schedule of Gardasil 9 among women aged 16-26 years old. The investigators thought that having a 2-dose vaccination regimen for individuals 16 to 45 would provide a more robust dataset than those of 27 to 45 years old.

This is a single arm immunological study based in Vietnam. The study will examine human papillomavirus (HPV) vaccine responses in high-risk women (female-sex-worker; FSW). We aim to recruit 60 women (aged 18-25 years old) and provide them with a standard 3-dose schedule of licensed 4vHPV vaccine (Gardasil®, Merck). Blood and cervical swab samples will be collected for immunology and virology testing, respectively.

This research study is studying Lenvatinib in combination with Pembrolizumab in people with human papillomavirus (HPV)-associated recurrent respiratory papillomatosis (RRP). The names of the study drugs involved in this study are: Pembrolizumab Lenvatinib
