The 2015 Conference on Retroviruses and Opportunistic Infections included new and exciting advances in the realm of antiretroviral therapy. The Temprano trial demonstrated benefits from early antiretroviral therapy and isoniazid preventive therapy. Important data on investigational antiretroviral drugs were presented, including tenofovir alafenamide fumarate and BMS-955176, an HIV-1 maturation ...

Registered in 2001, tenofovir disoproxil fumarate (TDF) has quickly become a mainstay of first line regimens for the treatment of HIV. Initially only available in developed countries at a cost of US$5 000 per person per year (ppy), Gilead's Access Programme (GAP) has extended the use of the product to 2.4 million patients in low and middle income countries. The programme has two components: dis...

BACKGROUND Efavirenz with tenofovir-disoproxil-fumarate and emtricitabine is a preferred antiretroviral regimen for treatment-naive patients infected with HIV-1. Rilpivirine, a new non-nucleoside reverse transcriptase inhibitor, has shown similar antiviral efficacy to efavirenz in a phase 2b trial with two nucleoside/nucleotide reverse transcriptase inhibitors. We aimed to assess the efficacy, ...

BACKGROUND There is a paucity of data on the effect of antiretroviral medications on male fertility. Couples affected by HIV-1 often have fertility intentions, and antiretroviral medications, as both treatment of HIV-1-infected persons and pre-exposure prophylaxis (PrEP) for uninfected persons, are part of peri-conception risk reduction. METHODS Within a randomized, placebo-controlled trial o...

INTRODUCTION More than a million people acquire HIV infection annually. Pre-exposure prophylaxis (PrEP) using antiretrovirals is currently being investigated for HIV prevention. Oral and topical formulations of tenofovir have undergone preclinical and clinical testing to assess acceptability, safety and effectiveness in preventing HIV infection. AREAS COVERED The tenofovir drug development pa...

Preclinical HIV prevention models use either a single high-dose viral challenge in depot medroxyprogesterone acetate-treated macaques or repeated viral challenges in cycling macaques. We tested the efficacy of an intravaginal tenofovir disoproxil fumarate (TDF) ring in a model combining repeated 30-mg injections of depot medroxyprogesterone acetate every 6 weeks with vaginal viral challenges we...

BACKGROUND Coinfection with human immunodeficiency virus type 1 (HIV-1) increases the risk of hepatitis B virus (HBV)-associated progressive liver disease. Lamivudine has potent activity against both HIV-1 and HBV; however, lamivudine-resistance mutations in HBV frequently develop. METHODS Substudies of the safety and efficacy of tenofovir disoproxil fumarate (tenofovir DF) for patients coinf...

Women and girls comprise nearly half of HIV-infected individuals globally and 20% of new infections in the United States, indicating an urgent need to optimise HIV prevention options in this population. HIV pre-exposure prophylaxis (PrEP) - where antiretrovirals are administered to HIV-non-infected individuals at risk of HIV acquisition - is a promising, female-controlled HIV prevention strateg...
