개요

Etravirine is a second-generation NNRTI. It is indicated for use in combination with other antiretroviral agents for treating HIV-1 infection in treatment-experienced adult patients who have evidence of viral replication and HIV-1 strains resistant to the currently available NNRTIs and other antiretroviral agents. The NNRTIs, along with nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs/NtRTIs), are important components of the combination regimens currently used to treat HIV-1 infection. The NRTIs/NtRTIs act by competing with the natural nucleotide substrates of reverse transcriptase for incorporation into viral DNA and subsequent chain termination. By contrast, the NNRTIs bind to an allosteric site of the enzyme and disrupt the DNA polymerase function by inducing conformational changes to the catalytic site. The allosteric binding nature of NNRTIs generally results in improved safety profile since there is no known human homolog for the drug-binding site of the enzyme.
As with other NNRTIs, etravirine has many drug–drug interactions. It is a substrate of CYP3A4, CYP2C9, and CYP2C19, an inducer of 3A4, and an inhibitor of 2C9 and 2C19. Caution should be used with co-administration of inducers, inhibitors, or substrates of these enzymes. Etravirine can be synthesized starting from 5-bromo-2,4,6-trichloropyrimidine through three successive nucleophilic substitution reactions. Initial displacement with 4-aminobenzonitrile using Hu¨nig’s base, followed by reaction with sodium salt of 4-hydroxy-3,5- dimethylbenzonitrile, and subsequent ammonolysis reaction with ammonia in dioxane under pressure affords etravirine. .

용도

A novel HIV reverse transcriptase inhibitor useful in treatment of HIV infection

용도

Etravirine (TMC125) is a non-nucleoside reverse transcriptase inhibitor (NNRTI) used for the treatment of HIV.

정의

ChEBI: An aminopyrimidine that consists of 2,6-diaminopyrimidine bearing a bromo substituent at position 5, a 4-cyano-2,6-dimethylphenoxy substituent at position 4 and having a 4-cyanophenyl substituent attached to the 2-amino group. NNRTI of HIV-1, binds directl to RT and blocks RNA-dependent and DNA-dependent DNA polymerase activities

원료

Various mutations are associated with a decreased virological response. Single codon substitutions at positions 100, 101 and 181 are considered major mutations. A single K103N mutation is not associated with resistance.

Pharmaceutical Applications

A comprehensive analysis of baseline resistance data from the DUET-1 and DUET-2 studies has identified a list of 17 etravirine resistance associated mutations: V901, A98G, L100L, K101E/H/I, V1061, E138A, V179D/F/T, Y181C/L/V, G190A/S, and M230L. A single K103N mutation is not associated with resistance to etravirine.

Pharmacokinetics

Oral absorption: Not known/available
Cmax 200 mg oral twice daily: c. 959 ng/mL
Cmin 200 mg oral twice daily: c. 469 ng/mL
Plasma half-life: c. 36 h
Volume of distribution: Not known/available
Plasma protein binding: >99%
Administration with food improves the bioavailability and reduces interpatient variability. It undergoes oxidative metabolism by cytochrome P450 systems. Around 93.7% and 1.2% of an administered dose can be retrieved in the feces and urine, respectively, mostly as unchanged drug.
Details of distribution into CSF, semen and breast milk and recommendations for dose adjustment in patients with hepatic impairment are not yet available.

Clinical Use

Treatment of HIV-1 infection in adults (in combination with other antiretroviral drugs)

부작용

In the phase III studies around 15% of patients experienced erythematous or maculopapular rashes of mild or moderate severity; most resolved with continued dosing, but treatment was discontinued in 2% of patients. Rare cases of Stevens– Johnson syndrome have been reported.
Other common adverse events are diarrhea, nausea, headache and fatigue. Dyslipidemia and raised pancreatic amylase occur in some patients.
