Use of a VR to provide sustained delivery of microbicides is a novel investigational method for prevention of heterosexual transmission of HIV in women. This drug delivery method may circumvent potential difficulties related to adherence to daily or coitally-dependent uses of microbicide regimens.

MTN-020 (ASPIRE) is a Phase 3, multi-site, randomized, double-blind, placebo-controlled clinical trial designed to evaluate the safety and efficacy of the dapivirine VR (25 mg) for the prevention of HIV-1 infection in healthy, sexually active, HIV-negative women. The study enrolled 2,629 participants who were randomized to receive either the 25 mg dapivirine VR or a placebo VR.  Participants were asked to use the study product for a minimum of 12 months.  Following VR use discontinuation, participants underwent an additional 4 weeks of follow-up to identify HIV-1 seroconversions that were not detected during the product-use period.  MTN-020 (ASPIRE) closed to follow-up at the end of June 2015.
