Feasibility Study of a Vaginal Ring for Delivery of TMC120 (Dapivirine)

• safety and tolerability of a vaginal ring containing TMC120 (dapivirine) [ Time Frame: 7 days ] [ Designated as safety issue: No ]
• TMC120 (dapivirine) concentrations in vaginal fluids, vaginal and cervical epithelial tissue, and plasma [ Time Frame: 7 days ] [ Designated as safety issue: No ]

The purpose of this trial was to evaluate the safety and feasibility of using a vaginal ring to deliver the candidate microbicide TMC120 (dapivirine). Twelve women initially underwent 7-day exposure to a placebo ring containing no investigational agent. They then underwent 7-day exposure to a ring containing 120 mg of TMC120 (dapivirine). Feasibility was assessed in terms of safety and tolerability as well as drug delivery.
