Indications

Biktarvy Tablets / Film-coated is used for: Bictegravir is indicated in the management of HIV-1 infection in patients not previously treated with antiretroviral therapy. Additionally, Bictegravir is indicated in the management of HIV-1 infection in patients who are virologically suppressed (HIV-1 RNA <50 c/mL) on a regular antiretroviral regimen for a minimum of three months without a history of failure in treatment and no known factors associated with the resistance to the individual components of the medication. It is used in combination with tenofovir and emtricitabine [L1219, L1220].

Mechanism of Action

This single dose medication inhibits the strand transfer of viral DNA into the human genome, preventing HIV-1 virus replication and propagation [L1218]. In vitro, bictegravir has shown powerful antiviral activity against HIV-2 and various subtypes of HIV-1. It has shown synergistic effects when combined with other ARVs, including tenofovir alafenamide (TAF), emtricitabine (FTC), and darunavir (DRV) [FDA LABEL]. The three components of the first USA approved medication ( trade name: Biktarvy ) are as follows: Bictegravir: integrase strand transfer inhibitor; INSTI), an HIV-1 encoded enzyme necessary for viral replication. Inhibition of the integrase enzyme prevents the integration of HIV-1 into host DNA, blocking the conversion of the HIV-1 provirus and progression of the virus [FDA LABEL]. Emtricitabine: FTC, is phosphorylated by cellular enzymes to form emtricitabine 5'-triphosphate. Emtricitabine is phosphorylated to form emtricitabine 5'-triphosphate intracellularly. This metabolite inhibits the activity of human immunodeficiency virus (HIV) reverse transcriptase by competing with the substrate deoxycytidine 5'-triphosphate and by incorporating itself into viral DNA preventing DNA chain elongation [FDA LABEL]. Tenofovir Alafenamide: TAF is a phosphonamidate prodrug of tenofovir (2'-deoxyadenosine monophosphate analog). Plasma exposure to TAF leads to leakage into cells and then TAF is intracellularly converted to tenofovir by hydrolysis by cathepsin. Tenofovir is subsequently phosphorylated by cellular kinases to the metabolite tenofovir diphosphate, which is the active form of the drug. Tenofovir diphosphate inhibits HIV-1 replication by incorporating into viral DNA by the HIV reverse transcriptase, resulting in DNA chain-termination. Tenofovir diphosphate also weakly inhibits mammalian DNA polymerases [FDA LABEL].
