Safety and Pharmacokinetics of TAF-FTC Pre-exposure Prophylaxis in Kenyan Cisgender Women

University of Washington·interventional·Posted Dec 2, 2021·Updated Jun 18, 2026

In Brief

A Phase 2 clinical trial evaluating co-formulated 25mg TAF/ 200mg FTC for HIV Infections. Completed, enrolled 54 participants across 1 site.

Detailed Summary

The study seeks to assess the safety of and define blood and tissue benchmark concentrations of tenofovir diphosphate (TFV-DP) and emtricitabine triphosphate (FTC-TP) in cisgender women using directly observed oral pre-exposure prophylaxis (PrEP) therapy with tenofovir alafenamide-emtricitabine (TAF-FTC). Cisgender women will be randomly assigned to receive varying frequencies of weekly PrEP doses and followed for up to 18 weeks.These data will help accurate interpretation of efficacy results obtained in HIV prevention trials and programs in cisgender women.
