Prazo: Week 24
Assessment for plasma HIV-1 RNA was done at Week 24 and also planned at Week 48 by polymerase chain reaction (PCR) analysis. Data is reported for number of participants with plasma HIV-1 RNA <400 copies/mL at Week 24. Data was not collected for Week 48 due to early termination of the study.
Week 24
Average Area Under the Curve Minus Baseline (AAUCMB) of Plasma HIV-1 RNA Through the Entire Study Period
Prazo: Up to Week 40
The area under the plasma HIV-1 RNA curve (AUC) was computed using the trapezoidal rule for all assessments (scheduled and unscheduled) at their actual time points. Baseline was defined as the mean of the Baseline (Day 1) and pre-treatment visit values. Participants without a Baseline assessment was removed from the analysis. The AAUCMB was computed by the AUC divided by the duration of the profile (i.e., the number of days on randomized therapy) minus the Baseline measurement. Data is reported up to Week 40 only due to early termination of the study.
Up to Week 40
Number of Participants With >= 1.0 log10 Copies/mL Decrease in Plasma HIV-1 RNA From Baseline Over Time
Prazo: Day 1 up to Week 12 Follow-up of the Randomized Treatment phase, up to Week 12 Follow-up of the Open Labeled Non-Randomized phase and every 6 months Follow-up of off study drug/on study phase
The plasma HIV-1 RNA polymerase chain reaction (PCR) assessments were planned at pre-Baseline (between 1 and 14 days prior to Day 1), up to Week 12 Follow- up of the Randomized Phase, up to Week 12 Follow-up of the Open Labeled Non-Randomized phase and every 6 months Follow-up of off study drug/on study phase, however the study was early terminated at Week 40. Baseline was defined as the mean of the Baseline (Day 1) and pre-treatment visit values.

Number of Participants Who Were Bothered by Each of Several Specific Symptoms Evaluated Using the HIV Symptom Index Questionnaire During the Randomized Treatment Phase
Prazo: Upto Week 48
The HIV Symptom Index Questionnaire was planned to be used to evaluate how bothersome certain symptoms were during the conduct of this clinical study. The participant self-report instrument had 20 items, each of which asked about a specific symptom or group of related symptoms that participants might have had during the past 4 weeks and the degree to which the participant is bothered by the symptom. The symptom index comprised 32 common and HIV-specific symptoms scored in terms of presence/absence (1, 0) and severity on a 4-point scale (0 = not at all to 3 =quite a bit). Higher score represented greater severity of symptoms.
