Background and study aims
As HIV-infected patients are living longer, non-AIDS-defining cancers (cancers which do not indicate the development of AIDS) are becoming much more common. Anal squamous cell carcinoma (ASCC) is one of the most common non-AIDS-defining cancers found in men who have sex with men (MSM). Around 90% of cases happen in individuals with a human papilloma virus (HPV) infection, the lesions (wounds) of which in the anal canal (back passage) are considered to increase risk of developing ASCC. One possible way to address this is to prevent HPV infections using the HPV vaccine. The aim of this study is to find out whether the HPV vaccine (qHPV) can help prevent the development of lesions in the anus that could lead to anal cancer.
Who can participate?
HIV positive adult MSM who have an anal infection caused by HPV.
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group receive injections of the qHPV vaccine into their shoulder muscle (deltoid muscle) at the start of the study and then three and six months later. Those in the second group receive placebo (dummy) injections into their shoulder muscle (deltoid muscle) at the start of the study and then three and six months later. For all participants, the injections are in the same arm each time. Participants undergo a scan of their anal canal to see whether there are any lesions so that the effectiveness of the vaccine can be assessed at the start of the study and then after 12, 24, 36 and 48 months. At the start of the study and then two and six months after each vaccination, participants complete a questionnaire about any side effects they have experienced as well as providing a blood sample.
What are the possible benefits and risks of participating?
Participants benefit from receiving screening, diagnosis and treatment of their HPV infection. Those who receive the qHPV vaccine could also benefit from continued protection against HPC infections and associated lesions which could develop into ASCC. There are no notable risks involved with participating in the study.

| Scientific title | Efecctiveness of of the quadrivalent human papillomavirus (qHPV) vaccine in HIV-positive Spanish men having sex with men (MSM): a double-blind randomised clinical trial |
| Study objectives | The tetravalent vaccine of HPV administered to patients MSM infected with HIV, not colonized by the serotypes administered in the vaccine, will produce a reduction in the incidence and progression of dysplastic lesions (AIN, carcinoma) of the anal mucosa, which will modify the protocols of screening of lesions and an improvement in the quality and expectations of these patients. |
| Ethics approval(s) | Comité de ética de la investigación de centro Granada, 26/03/2012 |
| Health condition(s) or problem(s) studied | Anal cancer related with HPV and HIV positive MSM |
| Intervention | Participants are randomised to one of two groups using Epidat 3.1 software: Vaccine group: Participants receive injections of 0.5ml Quadrivalent (HPVs 6/11/16/18) vaccine into the deltoid muscle at the baseline, 3 and 6 month study visits. All doses are competed in the same arm. Placebo group: Participants receive injections of 0.5ml placebo into the deltoid muscle at the baseline, 3 and 6 month study visits. All doses are competed in the same arm. Follow up for all participants (at 12, 24, 36 and 48 months) involves the recording of clinical-epidemiological variables, blood analyses (full blood haemogram and blood chemistry analytes were measured, together with CD4, CD8 lymphocytes counts, and HIV viral load (VL)), PCR of the HPV and anal cytology, high-resolution anoscopy (HRA), and testing for antibodies against the 4 genotypes of the qHPV vaccine. |
| Intervention type | Biological/Vaccine |
| Phase | Not Applicable |
| Drug / device / biological / vaccine name(s) | Not provided at time of registration |
| Primary outcome measure(s) |
Efficacy of the qHPV vaccine is assessed through the development of HSIL or anal cancer in anal mucosa using high resolution anoscopy at baseline and 48 months. |
| Key secondary outcome measure(s) |
1. Clearance of HPV genotypes in anal canal mucosa after vaccination is measured using PCR at baseline, 12, 24, 36 and 48 months |
| Completion date | 12/05/2017 |
