Number of Participants With Plasma HIV-1 RNA <400 Copies Per Milliliter (Copies /mL) at Week 24 and 48
Ramy czasowe: 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
Ramy czasowe: 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

Ramy czasowe: Up to Week 48 of Randomized Treatment phase and up to Switch + 24 Weeks of the Open Labeled phase
Adherence to investigational product was planned to be evaluated using pill counts of unused investigational product (blinded GW873140 or placebo, open-label GW873140 for open label phase). This assessment was planned to be conducted at each time the participant received a new (refill) supply of study medication.
Up to Week 48 of Randomized Treatment phase and up to Switch + 24 Weeks of the Open Labeled phase
Number of Participants Who Were Bothered by Each of Several Specific Symptoms Evaluated Using the HIV Symptom Index Questionnaire During the Randomized Treatment Phase
Ramy czasowe: 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.
Upto Week 48
