Learn about our Medical Review Board Latesha Elopre, MD, MSPH on September 25, 2020 Print Genvoya is a single-tablet, fixed-dose combination drug used in the treatment of HIV, which is comprised of four different antiretroviral drugs: Elvitegravir, an integrase inhibitorCobicistat, an HIV "booster" drugEmtricitabine, a nucleotide reverse transcriptase inhibitor (NtRTI)Tenofovir alafenamide (TAF), another NtRTI Genvoya is the first combination pill to use TAF, an "improved" version of tenofovir disoproxil fumarate (TDF) found in the drugs Truvada, Atripla, and Complera. As such, it can be considered an improvement on Stribild, the single-tablet formulation comprised of elvitegravir + cobicistat + emtricitabine + TDF. TAF is regarded as superior to TDF as it is able to deliver the active drug more effectively to cells and at far smaller doses—meaning that there is less build-up of the drug in the bloodstream and far less chance of developing drug-related kidney toxicities. (While the risk of TDF-associated kidney toxicity is considered low in developed countries, that risk is seen to rise considerably in developing countries where there is a greater incidence of pre-existing kidney dysfunction.) Gilead Sciences Treatment Indication Genvoya was approved by the U.S. Food and Drug Administration on November 5, 2015, for use in both adults and children over the age of 12 who have never been on HIV therapy and weigh over 77 lbs (35 kgs). It is also approved for adults on therapy who have a fully suppressed (undetectable) viral load. Formulation Genvoya is a green, oblong, film-coated tablet, comprised of 150mg of elvitegravir, 150mg of cobicistat, 200mg of emtricitabine and 10mg of TAF. It is embossed with "GSI" on one side and with a "510" on the other. Dosage One tablet is taken daily with food. Genvoya should not be taken with any other antiretroviral drug used to treat HIV.
