Fixed-dose combination tablets have become an important therapy option for patients infected with the human immunodeficiency virus. Fixed-dose combination rilpivirine-tenofovir-emtricitabine is a recently approved therapy option that has been extensively studied within the treatment-naïve population. When compared with efavirenz-based therapy, improved tolerability with rilpivirine-based therap...
BACKGROUND The roadmap approach is recommended to guide chronic hepatitis B treatment. We evaluated the cost-effectiveness of various treatment strategies in the global market. METHODS Lamivudine and telbivudine were tested in roadmap models with switch-to tenofovir if HBV was detectable at week 24 or add-on tenofovir if resistance developed at year 1. Tenofovir and entecavir were tested as c...
BACKGROUND Resistance to antiretroviral agents remains a leading cause of treatment failure for patients infected with HIV-1. OBJECTIVE To describe the efficacy and safety of tenofovir disoproxil fumarate (tenofovir DF) compared with placebo in patients with detectable viral replication despite current antiretroviral therapy. DESIGN Randomized, double-blind, placebo-controlled study through...
Drug-associated dysfunction of mitochondria is believed to play a role in the etiology of the various adverse symptoms that occur in human immunodeficiency virus (HIV)-infected patients treated with the nucleoside reverse transcriptase inhibitors (NRTIs). Tenofovir, a nucleotide analog recently approved for use in the treatment of HIV infection, was evaluated in vitro for its potential to cause...
Tenofovir disoproxil fumarate (tenofovir DF) is a bioavailable prodrug of tenofovir, a potent nucleotide analogue reverse-transcriptase inhibitor with activity against human immunodeficiency virus (HIV) and hepatitis B virus. It is administered as a single 300-mg tablet once daily. It was approved for the treatment of HIV infection on the basis of data from clinical trials demonstrating activit...
OBJECTIVES Zidovudine and tenofovir are the two main nucleos(t)ide analogs used to prevent mother-to-child transmission of HIV. In vitro, both drugs bind to and integrate into human DNA and inhibit telomerase. The objective of the present study was to assess the genotoxic effects of either zidovudine or tenofovir-based combination therapies on cord blood cells in newborns exposed in utero. DE...
The widely used antiretroviral agent tenofovir disoproxil fumarate has been associated with proximal tubular injury and decreased glomerular filtration rate in HIV-infected individuals. Phase 3 trials of a new prodrug, tenofovir alafenamide, suggest a lower potential for kidney injury.
BACKGROUND HIV-1 drug resistance to older thymidine analogue nucleoside reverse transcriptase inhibitor drugs has been identified in sub-Saharan Africa in patients with virological failure of first-line combination antiretroviral therapy (ART) containing the modern nucleoside reverse transcriptase inhibitor tenofovir. We aimed to investigate the prevalence and correlates of thymidine analogue m...
INTRODUCTION Truvada is licenced for HIV-1 prevention in the USA and is available in the private sector. Tenofovir performed as well as Truvada in the PARTNERS PrEP study and is used as HIV pre-exposure prophylaxis (PreP) in some settings. The clinical efficacy of Tenofovir for PrEP outside a clinical trial is unknown. Antiretroviral therapy (ART) at acute HIV-1 infection (AHI) limits the size ...
INTRODUCTION Previous research has demonstrated that tenofovir disoproxil fumarate (DF) is the most cost-effective nucleos(t)ide treatment for chronic hepatitis B (CHB) in the UK, Spain, Italy and France. However, to our knowledge, no published studies have yet evaluated the cost effectiveness of any treatments for CHB in a Canadian setting, where relative prices and management of CHB differ fr...
