Study Endpoints

Primary Endpoints

Frequency of Adverse Events
Assessed through the 10 week DOT dosing period

The frequency of graded adverse events by arm, including emergent HIV infection during the study period.

Concentrations of Tenofovir Disphosphate (TFV-DP) and Emtricitabine Triphosphate (FTC-TP) Measured at Ten Weeks in Dried Blood Spots (DBS)
Assessed at week 10

TFV-DP and FTC-TP concentrations observed in dried blood spots (DBS) after ten weeks of directly observed therapy with TAF-FTC oral PrEP, in women randomized to receive 2, 4, or 7 doses per week, representing poor, moderate, or perfect adherence, respectively.
