    Etravirine is a diarylpyrimidine non-nucleoside reverse transcriptase inhibitor. Etravirine is designed to be active against HIV isolates with mutations that confer resistance to the two most commonly prescribed first-generation NNRTIs. It can bind the enzyme reverse transcriptase (RT) in multiple conformations, both for native and mutant RT, thereby blocking the enzymatic activity of RT.
    Etravirine is a Human Immunodeficiency Virus 1 Non-Nucleoside Analog Reverse Transcriptase Inhibitor. The mechanism of action of etravirine is as a Non-Nucleoside Reverse Transcriptase Inhibitor, and Cytochrome P450 3A Inducer, and Cytochrome P450 2C9 Inhibitor, and Cytochrome P450 2C19 Inhibitor, and P-Glycoprotein Inhibitor.

    4.2 Drug Indication

    Indicated as an adjunct therapy in the treatment of adult HIV-1 infections resistant to therapy with other NNRTIs and antiretroviral agents.

    FDA Label

    Intelence, in combination with a boosted protease inhibitor and other antiretroviral medicinal products, is indicated for the treatment of human-immunodeficiency-virus-type-1 (HIV-1) infection in antiretroviral-treatment-experienced adult patients and in antiretroviral-treatment-experienced paediatric patients from six years of age.

    This indication is based on week-48 analyses from two phase-III trials in highly pretreated patients where Intelence was investigated in combination with an optimised background regimen (OBR) which included darunavir/ritonavir. The indication in paediatric patients is based on 48-week analyses of a single-arm, phase-II trial in antiretroviral-treatment-experienced paediatric patients.

    5 Pharmacology and Biochemistry
    5.1 Pharmacology

    Clinical trials have shown no prolongation of QT intervals on electrocardiograms after 8 days of dosing.

    5.2 MeSH Pharmacological Classification

    Reverse Transcriptase Inhibitors

    Inhibitors of reverse transcriptase (RNA-DIRECTED DNA POLYMERASE), an enzyme that synthesizes DNA on an RNA template. (See all compounds classified as Reverse Transcriptase Inhibitors.)

    5.5 Absorption, Distribution and Excretion

    Absorption

    Maximum oral absorption is achieved in 2.5-4 hours. Absorption is unaffected by the concomitant use of oral ranitidine or omeprazole, which decrease gastric acidity. Administration under fasting conditions resulted in a near 50% decrease in systemic exposure (AUC) when compared to administration after a meal.

    Route of Elimination

    After a 800mg dose of radio-labelled etraverine, 93.7% was found to undergo fecal elimination, with 81.2% - 86.4% eliminated unchanged. 1.2% of the dose was renally eliminated, changed. Etravirine is dialyzable (hemodialysis).

    Volume of Distribution

    Distribution of etravirine into compartments other than plasma has not been evaluated in humans.

    Clearance

    Renal clearance of etravirine is negligible (<1.2%), thus no dose adjustments are required in patients with renal impairment. Clearance is shown to be reduced in patients with Hepatitis B and/or co-infection, however, the safety profile of etravirine does not call for dosage adjustments.

    5.6 Metabolism/Metabolites

    Metabolized (in vitro) by the liver CYP450 enzymes: CYP3A4, CYP2C9, CYP2C19. The major metabolites formed by a methyl hydroxylation of the dimethylbenzonitrile moiety retained less than 90% of etravirine's activity.

    5.7 Biological Half-Life

    Half life of 9.05-41 hours.

    5.8 Mechanism of Action

    Etravirine exerts its effects via direct inhibition of the reverse transcriptase enzyme of human immunodeficiency virus type 1 (HIV-1). It directly binds reverse transcriptase and consequently blocks DNA-dependent and RNA-dependent polymerase activity. Etravirine does not inhibit human DNA polymerase alpha, beta or gamma.
