Background: Higher plasma tenofovir concentrations are associated with higher risks of renal and bone adverse events. The pharmacokinetic boosters ritonavir (RTV) and cobicistat (COBI) significantly increase plasma area under the curve (AUC) concentrations of tenofovir disoproxil fumarate (TDF), by 25-37%. When combined with RTV or COBI, the dose of tenofovir alafenamide (TAF) is lowered from 25 mg to 10 mg daily, but the TDF dose is maintained at 300 mg daily. Objective: To assess the differences in safety and efficacy between tenofovir alafenamide (TAF) and tenofovir disoproxil fumarate (TDF) in regimens with and without the pharmacokinetic boosters RTV and COBI...

BACKGROUND: The integrase inhibitor regimen (elvitegravir [EVG]/cobicistat [COBI]/emtricitabine [FTC]/tenofovir disoproxil fumarate [TDF]) demonstrated superior efficacy when compared to a protease inhibitor regimen (ritonavir-boosted atazanavir [ATV+RTV] plus FTC/TDF) in 575 treatment-naïve women at week 48. We investigated the efficacy, safety, and tolerability of switching to a TAF-based, single-tablet regimen containing EVG, COBI, FTC, and tenofovir alafenamide TAF (E/C/F/TAF) versus remaining on ATV+RTV and FTC/TDF...

The drug-drug interaction (DDI) potential between the fixed-dose combinations of ledipasvir/sofosbuvir 90/400 mg for hepatitis C virus and emtricitabine/rilpivirine/tenofovir alafenamide (TAF) 200/25/25 mg for HIV was evaluated in a randomized, open-label, single-center, multiple-dose, 3-way, 6-sequence, crossover Phase 1 study in 42 healthy subjects. Emtricitabine/rilpivirine/TAF had no relevant effect on the pharmacokinetic parameters of maximum concentration [Cmax ] and area under the concentration versus time curve over the dosing interval [AUCtau ] for ledipasvir, sofosbuvir, and the metabolites GS-566500 and GS-331007...

Tenofovir alafenamide (TAF) is an investigational prodrug of the HIV-1 nucleotide reverse transcriptase (RT) inhibitor (NtRTI) tenofovir (TFV), with improved potency and drug delivery properties over the current prodrug, tenofovir disoproxil fumarate (TDF). TAF is currently in phase 3 clinical studies for the treatment of HIV-1 infection, in combination with other antiretroviral agents. Phase 1 and 2 studies have shown that TAF was associated with increased peripheral blood mononuclear cell (PBMC) drug loading and increased suppression of HIV-1 replication compared to treatment with TDF...
