Human papillomavirus (HPV) is the most common sexually transmitted infection worldwide. Infection by certain high-risk oncogenic types of HPV (HR-HPV) is the major cause of several cancers in men, notably squamous cell carcinoma (SCC) of the anal canal. Rates of anal infection with these HR-HPV strains and the resultant high-grade anal dysplasia and anal cancer are much higher in men who have sex with men (MSM) than in the general population. Co-infection with human immunodeficiency virus (HIV) further amplifies this burden, making the rates of anal SCC in HIV-positive MSM higher than the historic rates of cervical cancer prior to the adoption of routine cervical cytology screening. Despite these alarming statistics, there are no established protocols for optimal screening and treatment of anal HPV and cancer precursors, nor has there been any widespread rollout of organized screening programs anywhere in Canada. Further, not only does HPV directly cause significant disease in these men, but there is growing epidemiologic evidence that HPV infection may enhance sexual transmission of HIV. These significant knowledge gaps translate into fundamental deficiencies in care for HIV-positive MSM.
The HPV Screening and Vaccine Evaluation in MSM (HPV-SAVE) study team will recruit a large group of MSM to carry out a number of different studies. One key component of recruitment entails the mailing of invitations with educational materials in an invitational package to subjects in order to determine who would be interested in having anal cancer screening. In this way, the investigators will reveal factors that are important in acceptance of screening.
The HPV-SAVE team brings together community and internationally-recognized experts in HPV and HIV disease and mucosal immunology, to better define the optimal approaches for primary and secondary prevention and treatment of HPV-associated anal disease among HIV-positive MSM, and to explore biological mechanistic evidence regarding the potential role of HPV as a co-factor for HIV transmission. This will yield critical information which can lead to improvement in the health of MSM, and will provide a foundation on which to build further, large-scale screening and treatment trials on a national level.
|Condition or disease||Intervention/treatment||Phase|
|Anal Dysplasia Human Papillomavirus Anal Cancer||Device: The Hyfrecator ® 2000 Electrosurgical System Other: Observation Alone||Not Applicable|
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||3000 participants|
|Intervention Model:||Parallel Assignment|
|Masking:||None (Open Label)|
|Official Title:||A Randomized Controlled, Open-label Trial Examining the Efficacy, Safety, and Tolerability of Ablative Therapies for High-grade Anal Dysplasia Versus Observation Alone in HIV-positive Men Who Have Sex With Men (MSM)|
|Study Start Date :||November 2015|
|Estimated Primary Completion Date :||November 2020|
|Estimated Study Completion Date :||December 2020|
Experimental: Ablative therapy
Ablative therapy involving electrocautery (EC) will occur for participants with AIN-2 and AIN-3. The Hyfrecator ® 2000 Electrosurgical System will be used for EC therapy.
Device: The Hyfrecator ® 2000 Electrosurgical System
Lesion is ablated by the The Hyfrecator ® 2000 Electrosurgical System. During electrocautery (EC) with The Hyfrecator, a gentle brushing technique occurs and the tissue is removed with forceps.
Other Name: EC
Active Comparator: Active Surveillance
The control arm includes active surveillance with observation alone; no treatment in AIN-2 and -3.
Other: Observation Alone
No treatment to AIN-2 or AIN-3, only active surveillance.
- Anal dysplasia treatment on a per-patient basis [ Time Frame: Participants will be followed after post-treatment completion, an expected average of 6 months ]Histologic resolution of high-grade AIN after treatment completion, with ablative therapies or surveillance alone. Resolution of high-grade AIN will be defined as histologic diagnosis of AIN-1 or normal at the post treatment HRA.
- Resolution of high-grade AIN at 3 and 6 months on a per-lesion basis [ Time Frame: Participants will be followed after post-treatment completion, an expected average of 6 months ]Resolution of high-grade AIN after treatment on a per-lesion basis. Histologic resolution of high-grade AIN after treatment completion, with ablative therapies or surveillance alone. Resolution of high-grade AIN will be defined as histologic diagnosis of AIN-1 or normal at the post treatment HRA.
- Acceptance rate of participants recruited into the study [ Time Frame: Participants will be followed after recruitment into the study, up to 4 years ]Acceptance rates of participant recruitment into the study via an invitational package for anal cancer screening which includes an invitation and educational brochure. Rates of acceptance will account for participants who positively respond to the invitational letter and reminder.
- Recurrence rates of high-grade AIN [ Time Frame: Participants will be followed after post-treatment completion, an expected average of 36 months ]Recurrence rates of high-grade AIN following ablative therapy on a per lesion basis.
- Number of participants with adverse events [ Time Frame: Participants will be followed after post-treatment completion, an expected average of 36 months ]Number of participants assessed on safety, tolerability and acceptability of the different intervention arms and the different treatments in the ablative therapies arms. Evaluation of adverse events and questionnaire-assessed acceptability by intervention arms and ablative treatment type.
