MTN-025, the HIV Open-label Prevention Extension (HOPE) trial, is a multi-site, open-label, randomized, Phase 3B trial that will be implemented if the dapivirine VR is found to be a safe and effective HIV prevention method in the MTN-020 (ASPIRE) trial.  Eligible HIV-uninfected ASPIRE participants will receive a silicone elastomer VR containing 25 mg of dapivirine, to be replaced monthly, for a total period of 12 months of use. Study follow-up visits will occur monthly for the first 3 months, and quarterly thereafter, reflecting a transition to a more real-world type of follow-up (versus a clinical trial approach).  The study will compare the safety of and participant adherence to dapivirine (25 mg) in a silicone elastomer VR. Should a woman choose not to take part in MTN-025, she will have the option of completing a brief survey and may be selected for qualitative evaluation assessing reasons for non-interest in enrolling.  The HOPE sample size will be contingent upon how many former ASPIRE participants are interested in enrolling, are HIV-negative and otherwise eligible to enroll.
