Filter by:The study will evaluate the immunogenicity and safety of 9-valent HPV recombinant vaccine in Chinese healthy females16 to 26 years of age.
To access the immune persistence of Chinese women aged 9-45 years after receiving quadrivalent HPV vaccine with the immunization schedule of 0, 2 and 6 months.
This phase 3 study will evaluate the immunogenicity and safety of Quadrivalent HPV recombinant vaccine in Chinese females aged 9 to 26 years
This phase 3 study will evaluate the immunogenicity and safety of 9-valent HPV recombinant vaccine in Chinese females aged 9 to 45 years
A randomized, double-blind and placebo-controlled phase I study to evaluate the safety and immunogenicity of a 9-valent Human Papillomavirus (HPV) vaccine, administered intramuscularly according to a 0, 2, 6-month schedule in 9 to 45 years old healthy Chinese females.
To evaluate the safety and primary immunogenicity of the quadrivalent human papillomavirus (types 6, 11, 16, 18) recombinant vaccine (hansenula polymorpha) in Chinese female subjects aged 9-45 years.
Background: - National Cancer Institute Protocol 04-C-N191, also known as the Costa Rica Vaccine Trial, was a double-blind controlled study of the effectiveness of an experimental human papillomavirus (HPV) vaccine in preventing cervical cancer in young women in Costa Rica. Costa Rica was part of the first large study to show the association between HPV and cervical cancer, and the study contributed greatly to the understanding of this association. The women who have participated in the vaccine trial in Costa Rica are reaching the end of the follow-up period offered in the vaccine trial protocol, and as a result they are being offered the chance to have complementary vaccinations against HPV, hepatitis A, and hepatitis B. Objectives: - To offer participants in the Costa Rica Vaccine Trial the vaccine that they did not receive during the masked portion of the trial (HPV vaccine or hepatitis A vaccine) and hepatitis B vaccination. - To collect information about exposure to known and suspected risk factors for HPV infection and cervical cancer from women who are receiving vaccination against HPV at crossover. Eligibility: - Women who participated in National Cancer Institute Protocol 04-C-N191. Design: - All participants will be offered vaccination against hepatitis B. - Women who received the hepatitis A vaccine during the trial will be offered vaccination against HPV. - Women who received the HPV vaccine during the trial will be offered vaccination against hepatitis A. - Appropriate vaccinations (including a combined hepatitis A and hepatitis B vaccine) will be available to reduce the number of injections that participants will be asked to receive. - All vaccines will be given according to the manufacturer's specifications for appropriate length of time between vaccine doses.
In a hospital-based multi-center study in China, HPV 16 was found to be the predominant type (72.9%) in cervical cancer, followed by HPV 18(8.0%) which indicated that if the HPV prophylactic vaccine are wisely applied in China, about 80% of cervical cancer can be prevented.The reported prevalence of HPV in the female population in China was about 13.2%, with women in the study between ages 15-55. HPV prevalence peaks in young adults (ages 20-24:15.5%) and pre-menopausal women (ages 45-49:15%) and this suggests an underestimation of cervical cancer burden in China. So far, there is no nation wide organized screening program in China, nor is the vaccine available for girls innocent to HPV infection. This study aims to vaccinate the daughters (aged between 13-15 yrs) living in the selected study areas thus to evaluate how cervical cancer and other HPV related diseases can be curbed through primary and secondary prevention(in company to screening the mothers aged 35-54 yrs) and to develop a China specific model for cervical cancer prevention through HPV vaccination and HPV DNA test (careHPV).
This is a phase IV study to evaluate the body's immune response of participants to the Cervarix and Gardasil vaccines against the Human Papilloma Virus (HPV) types associated with increased risk of cervical cancer.
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.
