Etravirine

{PARAM:[Name]}({[CAS]})
Category Human immunodeficiency Virus (HIV)
CAS 269055-15-4
Description Etravirine (ETR, brand name Intelence, formerly known as TMC125) is a drug used for the treatment of HIV. Etravirine is a non-nucleoside reverse transcriptase inhibitor (NNRTI). Etravirine works by reducing the amount of HIV and increasing the number of CD4 or T cells in the blood. Unlike the currently available agents in the class, resistance to other NNRTIs does not seem to confer resistance to etravirine.

In Vitro TMC125 is highly active against wild-type HIV-1 (50% effective concentration [EC50]=1.4 to 4.8 nM) and shows some activity against HIV-2 (EC50=3.5 μM). TMC125 also inhibits a series of HIV-1 group M subtypes and circulating recombinant forms and a group O virus. TMC125 has activity for 19 viruses with EC50 of < 5 nM.
In Vivo Etravirine has a high genetic barrier to the development of resistance. In phase IIb trials in treatment-experienced patients, including those infected with virus resistant to NNRTIs and protease inhibitors (PIs), TMC125 is active against HIV resistant to currently available NNRTIs, with a similar tolerability profile to that of the control group.

Description of First Aid Measures

Eye contact

Remove any contact lenses, locate eye-wash station, and flush eyes immediately with large amounts of water. Separate eyelids with fingers to ensure adequate flushing. Promptly call a physician.

Skin contact

Rinse skin thoroughly with large amounts of water. Remove contaminated clothing and shoes and call a physician.

Inhalation

Immediately relocate self or casualty to fresh air. If breathing is difficult, give cardiopulmonary resuscitation (CPR). Avoid mouth-to-mouth resuscitation.

Ingestion

Wash out mouth with water; Do NOT induce vomiting; call a physician.
