|Condition or disease||Intervention/treatment||Phase|
|Circumcision, Male||Device: Shang Ring Procedure: Male circumcision||Phase 2 Phase 3|
A randomized control trial of 400 adult male circumcision procedures with a one to one ratio between Shang Ring and the in-country standard surgical technique (forceps guided in Kenya and dorsal slit in Zambia)
Population: 400 men (200 at each site), HIV sero-negative men, ages 18-54, living in/around the two clinic sites seeking adult male circumcision
Duration: 2-4 months of recruitment; 60 days follow-up per participant; total expected duration of approximately 6 months in the field
Primary Objectives: (1) Compare the pain and acceptability of the Shang Ring procedure with the forceps guided surgical circumcision technique (Kenya) and the dorsal slit technique (Zambia) (2) Compare the safety and the course of wound healing, including the time to complete healing, between the Shang Ring adult male circumcision procedure and the standard surgical circumcision procedures (forceps guided in Kenya & dorsal slit in Zambia); (3) Compare the ease of the Shang Ring method versus standard circumcision surgical procedures
Primary Endpoints: (1) To compare the pain & acceptability of the circumcision methods, we will evaluate the following: post-operative pain; time to return to normal activity; patients' opinions of the Shang Ring and conventional procedures, and satisfaction with cosmetic results.
(2) To compare safety between methodologies, we will clinically compare and evaluate related adverse events and their severity. We will also compare the time to complete wound healing for each method. Complete wound healing is defined as no scab and dry skin by clinical assessment.
(3) We will evaluate the ease of surgery based on the duration of surgery and surgeons' opinions.

Active Comparator: 1
One group of men will undergo a circumcision using the Shang Ring and men are to return for regular follow-up visits to evaluate pain and wound healing. . The Shang Ring will be removed at 7 days, and the last scheduled follow-up visit is at 60 days.
Device: Shang Ring
The Shang Ring is a sterile device consisting of two concentric medical grade plastic rings: an inner ring with a silicone band and an outer, hinged ring. The inner ring fits inside the outer ring which will lock when snapped together. The Shang Ring comes in multiple sizes. The appropriate size is determined through use of a measuring strip. To ensure that men cannot remove the device prematurely, the locking mechanism must be broken open using a tool that is similar to a scalpel handle. Then, a pair of special scissors, specifically designed for this purpose, is used to remove the inner ring after healing
Active Comparator: 2
One group of men will undergo a conventional circumcision using a WHO recommended surgical technique, either the forceps-guided method or the dorsal slit method. Men are to return for regular follow-up visits to evaluate pain and wound healing, with the last scheduled follow-up visit at 60 days.
Procedure: Male circumcision
A conventional surgical procedure will be performed, per WHO recommendations, involving: drawing a line to mark the amount of foreskin to be cut; cutting off the foreskin; hemostasis; and wound closure with sutures.
- Pain scores on the Visual Analog Scale [ Time Frame: Within the first 48 hours after circumcision ]We will ask participants about pain they experienced during and soon after the procedure, and during the recovery period.
- Number of Participants with Adverse Events as a Measure of Safety and Tolerability [ Time Frame: Up to six weeks after surgery ]We will classify circumcision-related adverse events, using the detailed definitions of moderate and severe events per standardized protocol definitions, based on WHO recommendations. Most post-operative complications are apparent within six weeks of surgery.
- Compare the cost of the Shang Ring procedure versus conventional surgery [ Time Frame: Three months ]
