Dose Proportionality of TFV-DP After a Single Dose of GS-7340 in Women

Completed · Phase 1

Conditions studied: Healthy

In brief

Purpose: The purpose of this study is to characterize the dose-proportionality in the distribution of tenofovir alafenamide (TAF) and tenofovir (TFV) in plasma and mucosal tissues, and TFV-diphosphate (TFV-DP) in peripheral blood mononuclear cells (PBMCs) and mucosal tissues of healthy female subjects following a single oral dose of GS-7430 at 5mg, 10mg, and 25mg.
