Summary

The purpose of this study is to evaluate the pharmacokinetics, safety and antiviral activity of rilpivirine (TMC278) 25 milligram (mg) or adjusted dose once daily in combination with an investigator-selected background regimen containing 2 nucleoside/nucleotide reverse transcriptase inhibitors (N\[t\]RTIs) (zidovudine \[AZT\], abacavir \[ABC\], or tenofovir disoproxil fumarate \[TDF\] in combination with lamivudine \[3TC\] or emtricitabine \[FTC\] in antiretroviral (ARV) treatment-naïve adolescents and children aged greater than or equal to (\>=) 6 to less than (\<) 18 years.

Detailed description

This is a Phase II, open-label (all people involved know the identity of the assigned drug) and single arm study. The study will consist of a screening period of maximum 8 weeks, an initial treatment period of 48 weeks, a post week 48 treatment extension period of 4 years (Cohort 1 only), and a 4 week follow-up (cohort 2 only) period. Participants who withdraw from the trial on or before the Week 48 visit or subjects with ongoing (serious) adverse events (\[S\]AEs), laboratory abnormalities, or viral load increase at the last on-treatment visit in the extension, will be seen for a follow-up visit 4 weeks later. The initial 48-week treatment period will be structured into 2 age Cohorts; Cohort 1 (Aged greater than or equal to \[\>=\] 12 to less than \[\<\] 18 years) and Cohort 2 (Children Aged \>= 6 to \< 12 years). The trial is designed to evaluate the steady-state pharmacokinetic (PK) profile (based on intensive PK analysis) and the short-term safety and antiviral activity of rilpivirine (RPV). Participants will receive RPV 25 milligram (mg), or weight-adjusted dose orally once daily for 240 weeks when administered in combination with 2 nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs). The trial will also evaluate long-term (48 weeks and 240 weeks \[Cohort 1\]) safety, efficacy, and pharmacokinetics of rilpivirine in combination with the background regimen of 2 NRTIs. Patients safety will be monitored throughout the study and during the follow up visits.

DRUG	Zidovudine	Type=exact, form= appropriate pediatric formulation, unit=mg, route=oral. The patients may receive this selected NRTI together with another NRTI once daily for up to 48 weeks (Cohort 2) and 240 weeks (Cohort 1).
DRUG	Abacavir	Type=exact, form=appropriate pediatric formulation, unit=mg, route=oral. The patients may receive this selected NRTI together with another NRTI once daily for up to 48 weeks (Cohort 2) and 240 weeks (Cohort 1).
DRUG	Tenofovir disoproxil fumarate	Type=exact, form=appropriate pediatric formulation, unit=mg, route=oral. The patients may receive this selected NRTI together with another NRTI once daily for 240 weeks (Cohort 1).
DRUG	Lamivudine	Type=exact, form=appropriate pediatric formulation, unit=mg, route=oral. The patients may receive this selected NRTI together with another NRTI once daily for up to 48 weeks (Cohort 2) and 240 weeks (Cohort 1).
DRUG	Emtricitabine	Type=exact, form=appropriate pediatric formulation, unit=mg, route=oral. The patients may receive this selected NRTI together with another NRTI once daily for up to 48 weeks (Cohort 2) and 240 weeks (Cohort 1).
