Effectiveness and Safety of Tenofovir Disoproxil Fumarate in Chronic Hepatitis B: A 3-Year, Prospective, Real-World Study in France.

Background And Aims: Tenofovir disoproxil fumarate (TDF) demonstrated potent and sustainable antiviral efficacy and a good safety profile in patients with chronic hepatitis B (CHB) in controlled clinical trials. Real-world data are important to confirm effectiveness and safety data in patient populations encountered in routine clinical practice.

Methods: This non-interventional, prospective, 36-month study included treatment-naïve and treatment-experienced patients with CHB initiating their first TDF regimen (monotherapy or combination therapy) in routine clinical practice in France.

A randomized trial of two-drug versus three-drug tenofovir-containing maintenance regimens in virologically controlled HIV-1 patients.

Objectives: To assess simplified maintenance regimens containing dual antiretroviral drugs in patients with controlled human immunodeficiency virus type 1 infection.

Methods: A non-inferiority, randomized, multicentre, open-label trial was performed in 24 AIDS clinical centres in France randomizing 143 patients [treated for >or=6 months, plasma viral load (pVL) <50 copies/mL, no prior history of treatment failure] to receive a two-drug regimen [tenofovir disoproxil fumarate (tenofovir DF) and efavirenz] or to maintain a three-drug treatment (tenofovir DF, lamivudine and efavirenz). The main outcome measure was the success rate (percentage of patients with pVL <50 copies/mL without treatment modifications) at week 48.
