Background and study aims
The Human Papilloma Virus (HPV) is a common virus that is known to have more than 100 types, and is spread through close skin contact and sexual contact. It is estimated that about 75% of women will become infected with one or more of the sexually transmitted HPV types at some point during adulthood. HPV is the virus that causes genital warts. Long-term infection with one or more of about a dozen so-called ‘high-risk’ sexually transmitted HPV types can lead to the development of cell changes in the cervix, called dyskaryosis, which may in turn lead to cancer of the cervix. HPV infection is responsible for the development of nearly all cases of cervical cancer. Although the widespread use of Pap testing programs has greatly reduced the incidence and death rates from cervical cancer in developed countries, the disease still kills several hundred thousand women per year worldwide. Possibly due to a decrease in the function of the immune system (the cells and substances in the body that protect the body from infection), HIV-positive women are known to have higher rates of HPV infection, and more rapid progression to cervical cancer. In addition, they are troubled by larger external genital warts that tend to be more difficult to treat. The GARDASIL™ vaccine will protect against four types of HPV; two of these types are associated with genital warts and the other two are the high-risk, cancer-causing HPV types. The GARDASIL™ studies so far have shown excellent protection against these types of HPV in healthy women and girls. To date, there are no study results for the evaluation of the safety and effectiveness of this HPV vaccine in HIV-infected persons. The aim of this study is to investigate the safety and effectiveness of giving the HPV vaccine to women infected with HIV. Many of the women over the age of about 20 will already have been exposed to HPV. However, there is research that suggests that only about 7.5% of women with HIV have ever tested positive for one of the genital wart associated types of HPV in the vaccine, and only about 16% have ever tested positive for one of the cancer associated types, suggesting that the vaccine can still offer some protection against HPV infection. We want to study whether women and girls with HIV can be protected from some or all of the types of HPV found in the vaccine.
Who can participate?
Women and girls aged 9 or older with HIV
What does the study involve?
This study involves seven to eight visits, spaced out over 2 years and 3 months. All of the study visits, except one, are scheduled on the same day as routine clinic visits for HIV care. At the start of the study participants undergo assessments (clinical labs, physical assessment, medical history, study samples). At least 3 months later, participants have additional assessments and are then vaccinated with Gardasil. Additional Gardasil vaccinations take place 2 and 6 months following the first vaccination. Participants are followed up every 6 months for up to 24 months. Study procedures include: clinical labs, cervical cytology (smear test), physical examinations, and HPV antibody serology (blood tests).
What are the possible benefits and risks of participating?
Participants may benefit from protection against some types of HPV, and therefore potential cervical cancer, as a result of being vaccinated. The knowledge gained from this study may help others who are living with HIV/AIDS in the future. As for any vaccine, vaccination with GARDASIL™ may not result in protection for all people who get it. In previous studies GARDASIL™ has been generally well tolerated.

| Scientific title | A study of a human papillomavirus (HPV) virus-like particle (VLP) vaccine in a cohort of human immunodeficiency virus (HIV) positive girls and women |
| Study objectives | It is hypothesised that human papillomavirus (HPV) vaccination will result in a variable immune response and consequently differential vaccine effectiveness in some human immunodeficiency virus (HIV) infected girls and women, and that co-factors including T-cell immune dysfunction, age, prior HPV infection, injection drug use and ethnicity will substantially affect this response. |

| Health condition(s) or problem(s) studied | Human immunodeficiency virus, human papillomavirus |
| Intervention | Following informed consent/assent, subjects will have a baseline visit to assess eligibility and to obtain baseline assessments (clinical labs, physical assessment, medical history, baseline study samples). At least 3 months later, subjects will have additional assessments and then be vaccinated with Gardasil. Additional Gardasil vaccinations will take place 2 and 6 months following the first vaccination. Subjects will be followed every 6 months for up to 24 months. Study procedures will include: clinical labs, clinical cervical cytology, physical examinations, and study cervical cytology and HPV antibody serology. |
| Intervention type | Biological/Vaccine |
| Pharmaceutical study type(s) | |
| Phase | |

To compare the level of circulating antibody to specific vaccine containing HPV genotypes in vaccinated girls and women by a proprietary assay and two independent laboratory assays 3. To determine the rate of adverse events in HIV infected girls and women given an HPV VLP vaccine compared to their baseline rate of adverse signs and symptoms |
