The purpose of this study is to investigate the ability of TMC125, a Non-Nucleoside Reverse Transcriptase Inhibitor (NNRTI), to lower the amount of virus in your blood when administered twice daily for 48 weeks.
TMC125 will be given in addition to a combination of anti-HIV drugs that have been selected specifically for you by your doctor. There are three treatment groups in the study. One group will be given a dosage of TMC125, 400 mg twice daily. Another will be given 800 mg twice daily. The third group, a control arm, will not receive TMC125 (formulation TF035). The safety, tolerability and pharmacokinetics (determinations of the concentration of drug in your blood and its evolution over time) of TMC125 will also be evaluated in this study. Patients who have known resistance to NNRTIs and 3 or more protease inhibitor (PI) mutations may be eligible to participate. One-hundred-fifty (150) patients will be enrolled into this study. TMC125, 400mg twice daily for 48 weeks; TMC125, 800mg twice daily for 48 weeks.

The primary objective of the trial is to evaluate the dose-response relationship of antiviral activity at 24 weeks within the two TMC125 dose regimens.
Evaluate the antiviral activity, safety and tolerability of TMC125, immunologic changes, changes in viral genotype and drug suseptibility, PK of TMC125 and compare antiviral effect among treatment groups
