- Area Under the Plasma Concentration-Time Curve From Time of Administration to 12 hours After Dosing (AUC 0-12h) - Part 1 [ Time Frame: Week 2 ]The Area Under the Plasma Concentration-Time Curve (AUC) is a measure of the plasma concentration of the drug over time. It is used to characterize drug absorption.
- Predose Plasma Concentration (C0) - Part 1 [ Time Frame: Week 2 ]The C0 is the predose plasma concentration.
- Maximum Observed Plasma Concentration (Cmax) - Part 1 [ Time Frame: Week 2 ]The Cmax is the maximum observed plasma concentration.
- Recommended Dose of TMC114 per Body Weight [ Time Frame: Week 2 ]The recommended dose of TMC114 will be determined in participants with a body weight: greater than and equal to 20 Kilogram (kg) to less than 30 kg; greater than and equal to 30 kg to less than 40 kg; and greater than 40 kg.
- Change From Baseline in Plasma Viral Load at Week 2 - Part 1 [ Time Frame: Baseline and Week 2 ]Plasma viral load levels will be determined using Roche amplicor human immunodeficiency virus (HIV)-1 monitor test (Version 1.5).
- Change From Baseline in Plasma Viral Load at Week 24- Part 2 [ Time Frame: Baseline and Week 24 ]Plasma viral load levels will be determined using Roche amplicor HIV-1 monitor test (Version 1.5).
- Number of Participants With Adverse Events [ Time Frame: Week 2 ]Adverse event is defined as any untoward medical occurrence in a participant or clinical investigation participant administered with a pharmaceutical product and which does not necessarily have a causal relationship with the treatment.
- Number of Participants With Adverse Events [ Time Frame: Week 24 ]Adverse event is defined as any untoward medical occurrence in a participant or clinical investigation participant administered with a pharmaceutical product and which does not necessarily have a causal relationship with the treatment.
- Change From Baseline in Plasma Viral Load at Week 48 - Part 2 [ Time Frame: Baseline and Week 48 ]Plasma viral load levels will be determined using Roche amplicor HIV-1 monitor test (Version 1.5).
- Change from Baseline in Cluster of Differentiation 4 (CD4+) cell count - Part 2 [ Time Frame: Baseline and Week 48 ]The immunologic change will be determined by changes in CD4+ cell count.
- Number of Participants With Resistance - Part 2 [ Time Frame: Week 48 ]Resistance will be determined by viral phenotype and genotype determinations, which will be performed by Virco BVBA, by means of the antivirogram and Virco type HIV-1 respectively. Resistance determinations will only be generated if the viral load is greater than 1000 HIV-1 RNA copies/milliliter.
- Area Under the Plasma Concentration-Time Curve From Time of Administration to 12 hours After Dosing (AUC 0-12h) - Part 2 [ Time Frame: Week 48 ]The Area Under the Plasma Concentration-Time Curve (AUC) is a measure of the plasma concentration of the drug over time. It is used to characterize drug absorption.
- Predose Plasma Concentration (C0) - Part 2 [ Time Frame: Week 48 ]The C0 is the predose plasma concentration.
- Oral Clearance (CL/F) - Part 2 [ Time Frame: Week 48 ]The CL/F is the oral clearance; that is clearance based on oral bioavailability.
