  Purpose

This prospective, randomized, single-blinded, placebo controlled trial will examine the safety and pharmacokinetics (PK) of a polyurethane tenofovir disoproxil fumarate (TDF) vaginal ring when used continuously for 14 consecutive days.

The primary objective is to assess the safety of TDF vaginal rings when used continuously for 14 days by healthy, HIV-uninfected, sexually abstinent women, as compared with a placebo vaginal ring.

Primary Outcome Measures:
  • Genitourinary events Grade 1 or higher judged to be related to study product. [ Time Frame: 14 days of vaginal ring use ]
    Adverse Events as defined by the DAIDS Table for Grading the Severity of Adult and Pediatric Adverse Events

  • Adverse events Grade 2 or higher [ Time Frame: 14 days of vaginal ring use ]
