  Objectives: Self-administered vaginal rings are a promising method for delivery of topical anti-HIV microbicides and might offer an adherence advantage over daily or coitally-dependent dosage forms such as gels. This trial assessed the safety and pharmacokinetic aspects of the Dapivirine Vaginal Ring-004 when worn as multiple rings over sequential periods of ring use by healthy, sexually-active, HIV-negative women.

Group A used two rings over a 56-day period and Group B used three rings over a 57-day period. Safety evaluations were conducted throughout the trial. Dapivirine concentrations were measured in plasma, vaginal fluid and cervical tissue samples collected during and after the.. Read More»
