Phase 2 Adherence and Pharmacokinetics Study of Oral and Vaginal Preparations of Tenofovir
A new approach to HIV prevention currently being studied includes the use of microbicides, substances that kill microbes. Tenofovir disoproxil fumarate (TDF) is an oral, FDA-approved, anti-HIV drug, and tenofovir gel is an experimental microbicide. The purpose of this study is to determine the adherence and acceptability to and blood levels of three daily regimens of tenofovir in both oral and gel form.

Conditions
- HIV Infections
Interventions
- Tenofovir disoproxil fumarate
- Tenofovir gel
Primary outcomes
- Self-reported Adherence to Each Regimen — Measured through Week 21
Participant self-reported product use. For each woman, adherence to each regimen was computed by dividing the number of daily doses she reported having taken by the number of doses expect if she were fully adherent. - Proportion of Participants Who Indicate They Would be "Unlikely" Use Study Product in the Future — Measured through Week 21
- Systemic and Local PK Among Three Regimens of Tenofovir (Oral, Vaignal, and Dual Use) — Measured through Week 21
PK measures, including maximum concentrations (Cmax) in serum, tissue, and cervicovaginal lavage.
