A Phase I Study of Quadrivalent Human Papilloma Virus (HPV) (Types 6, 11, 16, 18) Recombinant Vaccine in HIV-Infected and HIV-Negative Pre-Adolescents, Adolescents, and Young Adults

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Background: * Human papilloma virus (HPV) is a common sexually transmitted disease. There are more than 100 different HPV types, and both males and females can get HPV infection. Most people do not have any symptoms when they become infected and are able to get rid of the infection on their own. However, they can still become re-infected with the same or a different HPV type, and in some people HPV infection persists. * Persistent HPV infection is associated with the development of precancerous lesions and cancer. HPV types are classified as either high risk or low risk based on whether their persistence will lead to cancer. * Patients who have suppressed immune systems are at a higher risk for HPV-related complications. They are more likely to contract multiple HPV types and have more persistent infection that can lead to precancerous lesions or cancer, which are then difficult to treat and often recur. * A recently approved vaccine for HPV induces immunity to HPV 6, 11, 16, and 18. It was shown to be highly effective in preventing infection with these HPV types, and is approved for use in females 9 to 26 years of age. However, much less is known about the vaccines ability to induce immunity in males or individuals with suppressed immune systems. Objectives: \- To investigate whether the HPV vaccine is safe to give and able to induce immunity in both female and male adolescents and young adults with HIV infection compared to healthy, human immunodeficiency virus (HIV)-negative persons of the same age. Eligibility: \- Males and females, 12 to 26 years of age, divided into three groups: (1) Healthy and HIV-negative, (2) HIV-positive and on antiretroviral therapy, and (3) HIV-positive and not on antiretroviral therapy. Design: * Before beginning vaccination, participants will have a complete physical examination and blood drawn for routine blood tests, special tests of the immune system, antibody tests, and an HIV test. * HPV vaccine will be given by injection into the muscle at 0, 2, and 6 months, according to the standard vaccination schedule. * Patients with HIV infection will be monitored for a week following the first injection to test the level of HIV in the blood 3 days and 5 days after the first injection. * Participants will also be asked to fill out a 10- to 15-minute Web-based survey about awareness, health behaviors, and personal choices related to risk factors for HIV, HPV, and other sexually transmitted diseases. Participants are not required to fill out the survey to receive the vaccine. * The total duration of the study is 4 years. During the first year of the study, participants will return for six additional 1-day visits at months 1, 2, 3, 6, 7, and 12. Participants will return for 1-day visits every 6 months for the remaining 3 years.
