Safety and Acceptability of the PrePex™ Device for Male Circumcision in Zambia
- Conditions
- HIV
- Interventions
- Device: PrePex
- Registration Number
- NCT01844102
- Lead Sponsor
- FHI 360
- Brief Summary
The study will measure the incidence of moderate and severe adverse events (AEs) associated with PrePex procedures among 500 men, including both procedural and post-procedure events, and all device-related incidents such as dislodgment. To assure complete ascertainment of AEs, study-specific forms will be used to collect standardized data from the circumcision visit and all follow-up visits. Follow-up will be more intensive for the first 50 cases, and will transition to follow-up at two visits (7 and 42 days) for the remaining 450 cases.
- Detailed Description
The World Health Organization, the Joint United Nations Programme on HIV/AIDS (UNAIDS), and other global reproductive health organizations have recognized the protective effect of male circumcision in HIV acquisition. Male Circumcision(MC) is one of the few biomedical methods to demonstrate consistent effectiveness as an HIV prevention intervention in randomized controlled trials (WHO and UNAIDS, 2007): three randomized controlled trials (RCTs) in Kenya, Uganda, and South Africa reported a protective effect up to 60% of circumcision against HIV infection. Subsequent studies have confirmed the value and persistence of MC's protection against HIV infection and have demonstrated that MC also reduces the acquisition and transmission of human papillomavirus.
A wide variety of instruments, devices, and techniques are used around the world for male circumcision. In 2008, WHO, UNAIDS and JHPIEGO released a draft document entitled Manual for Male Circumcision under Local Anesthesia, which includes step-by-step instructions for performing adult male circumcision using three different surgical procedures: the forceps-guided, dorsal slit, and sleeve resection methods. Procedure times for these techniques are approximately 20-30 minutes excluding anesthesia, involve control of bleeding and considerable suturing, and can be associated with a variety of complications.
Demand for MC, even in non-circumcising communities, is substantial when offered at no cost in a safe setting (WHO and UNAIDS, 2007). In most African settings, only surgical circumcision is available for most adults.
This is a prospective observational study of the PrePex device, which will be conducted with the aim of ascertaining moderate and severe adverse events. This study will be conducted within the context of routine service delivery in Lusaka, Zambia to identify potential issues that must be addressed as MC services are scaled up. PrePex circumcision procedures will be offered as part of the minimum package of HIV prevention services recommended by the Zambian Ministry of Health (MOH), including HIV testing and counseling, provision of Sexually Transmitted infection (STI) syndromic treatment, provision and promotion of condoms, and counseling on risk-reduction and safer sex. This study will be conducted in collaboration with the Zambia MOH and will follow recommendations for introductory study of devices as laid out in the WHO's Framework for Evaluation of Circumcision Devices.
This study is a prospective study of adult male circumcision procedures conducted with the PrePex MC device at two sites in Lusaka, Zambia. The investigators will enroll a total of 500 men aged 18 to 49 who are seeking voluntary medical male circumcision. The first 50 men will undergo intensive follow-up with six scheduled visits, while the remaining 450 men will be scheduled for two follow-up visits at 7 and 42 days after PrePex placement.
