Safety, PK, and PD Study of a Vaginal Insert Containing TAF and EVG

Completed · Phase 1

Conditions studied: Hiv, HSV

In brief

The purpose of this Phase I study is to assess the safety, pharmacokinetics, and pharmacodynamics of a combination vaginal insert containing tenofovir alafenamide (TAF) and elvitegravir (EVG). This study will be the first-in-human study for a vaginally administered TAF/EVG insert and will evaluate safety, PK and PD after a single dose. It is hypothesized that the combination insert will be safe and well-tolerated by study participants and that the insert will offer an expanded window of preventive activity and a regimen with flexibility and forgiveness.
