ChallengesSurgical male circumcision poses some challenges…
• Fear of pain, complications from surgery, and loss of work as barriers to uptake
• Surgically skilled providers are limited and difficult to assign to an elective procedure
• Suitable infrastructure and commodities are scarce and difficult to dedicate to an elective procedure
• Feasibility of scale-up may be questioned given the resources needed and the scope of the surgical task
Ideally, a medical device for VMMC would alleviate these challenges

The ‘Ideal’ Medical Device for MC
• Effective, safe, inexpensive, highly acceptable• No injection of local anesthesia• Minimal discomfort/pain• No sutures (bloodless)• Cause minimal disruption in daily activities• Does not require physician to place/remove device• Single provider could place device; single provider could
remove device• Sterile environment not required (no cutting of living tissue)• Self detaching if left in place beyond recommended time
– Manufacturer applies for pre-qualification – If accepted, manufacturer completes product dossier
One element of a dossier is clinical evidence, in line with WHO TAG recommendations. • Initial safety and efficacy study• Randomized controlled trials in 2 countries comparing device to surgery • Field Studies in 2 countries under conditions of final use
Study data are reviewed by WHO Technical Advisory Group on Innovations in Male Circumcision and report provided to inform product dossier and pre-qualification decision
– Manufacturing site inspection/audit(s)

Funding
• Governments and donors may determine their own requirements before implementing devices (may be informed by WHO Framework)
• PEPFAR requires WHO pre-qualification before wide-scale funding of device(s)– Limited funds available now for small acceptability
and safety studies of PrePex, given US FDA marketing approval
