Introduction to Devices for VMMC: Potential to Accelerate Scale-up, Approval Processes, and Status of Clinical Trials Jason Reed, MD, MPH Sr. Technical Advisor for Male Circumcision Programming Office of the Global AIDS Coordinator
Challenges Surgical malecircumcision poses some challenges… • Fear of pain, complications from surgery, and loss of work as barriers to uptake • Surgically skilled providers are limitedand 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
WHO Pre-Qualification Process • 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)

Pre-Qualification Status 1Bitega, JAIDS, 2011 2Mutabazi, 16th ICASA Ethiopia, 2011
Pre-Qualification Status 1Barone, JAIDS, 2011 2Awori, 16th ICASA Ethjopia, 2011
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
