| In vitro study | Etravirine (TMC125), is high active against wild-type HIV-1 with EC50 of 1.4 nM to 4.8 nM and shows some activity against HIV-2 with EC50 of 3.5 μm. TMC125 also inhibit a series of HIV-1 group M subtypes and circular combined forms and a group O virus. Etravirine (TMC125) was highly effective against wild-type HIV-1, with an EC50 of 1.4 nM to 4.8 nM, and showed some activity against HIV-2, with an EC50 of 3.5 μm. TMC125 also inhibits a series of HIV-1 M-type subunits and circulating recombinant forms as well as O-type Virus. |
| In vivo study | Etravirine has a high genetic barrier to the development of resistance. In phase IIb trials in treatment-experienced patients, included with virus resistant to NNRTIs and protein inhibitors (PIs), TMC125 is active against HIV resistant to current available NNRTIs, with a similar tolerance profile to that of the control group. Etravirine has a high genetic barrier to resistance development. In the Phase IIb trial, TMC125 was active against existing NNRTIs-resistant HIV in multiple-treated patients, including those infected with NNRTIs-resistant and protease inhibitor-resistant (PIs) Virus, similar tolerability to the control group. |
