This is a Phase III, open-label (all people know the identity of the drug), multicenter, roll-over trial to provide continued access to TMC278 to HIV-1 infected patients who were randomized (the study drug is assigned by chance) and treated with TMC278 in the Phase IIb (TMC278-C204 \[C204\]) or Phase III trials (i.e., TMC278-TiDP6-C209 \[C209\] or TMC278-TiDP6-C215 \[C215\]) and who continue to benefit from their antiretroviral treatment, according to the investigator. In addition, information on the long-term safety and tolerability, including resistance data in case of virologic failures, of oral doses of TMC278 25 mg once daily (q.d.) in combination with a background regimen containing 2 N(t)RTIs will be collected. Available efficacy data will also be collected. Approximately 750 HIV-1 infected individuals are expected to participate in this trial. The duration of participation in the study for an individual participant will be 2 to 3 years. The final/withdrawal visit of the Phase IIb or Phase III trials will be the first visit of this trial. Safety and tolerability will be evaluated throughout the trial. Visits and assessments performed should be based on the local, generally accepted standard of care, with visits occurring at least every 6 months. Oral tablets of TMC278 25 mg once daily (q.d.) should be administered together with a meal.
