The study is designed to select a dose of GSK1265744 primarily on the basis of antiviral activity and tolerability in HIV-1 infected, antiretroviral naive subjects. This study consists of two parts: Induction Phase: Approximately 200 subjects will be randomized (50 subjects in each of the 4 treatment arms). The Induction Phase consists of a 24 week dose-ranging evaluation of GSK1265744 at blinded doses of 10 mg, 30 mg and 60 mg once-daily and a control arm of open-label efavirenz (EFV) 600 mg once daily. The background dual nucleoside reverse transcriptase inhibitor (NRTI) antiretroviral therapy (ART) for all arms will be either abacavir/lamivudine (ABC/3TC) or tenofovir/emtricitabine (TDF/FTC) as selected by the Investigator. Subjects randomized to a GSK1265744 containing arm, who successfully complete 24 weeks on study and demonstrate virologic suppression (defined as having a plasma HIV-1 ribonucleic acid \[RNA\] \<50 copies per milliliter \[c/mL\] before Week 24, with no signs of virologic rebound) will become eligible for the Maintenance Phase of this study. Maintenance Phase: The background NRTIs will be discontinued and the subjects will continue their randomized dose of GSK1265744 in combination with rilpivirine (RPV) 25 mg once-daily for an additional 72 weeks. The Maintenance phase will evaluate the ability of this two drug ART regimen to maintain virologic suppression through Week 48, Week 72 and Week 96. Subjects randomized to the EFV arm will continue on their randomized regimen through Week 96. After completion of the maintenance phase, subjects could enroll in the Open-Label Phase to continue GSK1265744 + RPV treatment as long as they continue to derive clinical benefit and until it is locally approved and commercially available.

Percentage of Participants With HIV-1 Ribonucleic Acid (RNA) <50 Copies/Milliliter (mL) at Week 48 Using the Missing, Switch, Discontinuation Equals Failure (MSDF) Algorithm
Plasma samples were collected for quantitative analysis of HIV-1 RNA. Percentage of participants with HIV-1 RNA \<50 copies/mL at Week 48 was determined using the MSDF algorithm based on the current US Food and Drug Administration (FDA) definition of Snapshot algorithm. This algorithm treats all participants without HIV-1 RNA data at the visit of interest (due to missing data or discontinuation of investigational product prior to visit window) as well as participants who switch their concomitant antiretroviral therapy prior to the visit of interest as non-responders. Virological response within an analysis window was determined by the last available HIV-1 RNA measurement in that window while the participant was on-treatment. MSDF response rate was calculated as number of responders in the analysis window divided by the number of participants in the analysis population. ITT-E Population comprised of all randomized participants who received at least one dose of investigational product.

The PK Summary Population comprised of all participants who received GSK1265744 or with Rilpivirine, underwent intensive and/or limited/sparse PK sampling during the study, and provided evaluable GSK1265744 and Rilpivirine plasma concentration data
Time frame: pre-dose, 1, 2, 3, 4, 8 and 24 hours post-dose at Week 2
Maximum Observed Concentration (Cmax) for GSK1265744 at Week 2
Blood samples for PK analysis were collected at the indicated time points. The PK parameters were calculated by standard non-compartmental analysis.
Time frame: pre-dose, 1, 2, 3, 4, 8 and 24 hours post-dose at Week 2
Concentration at the End of a Dosing Interval (Ctau) for GSK1265744 at Week 2
Blood samples for PK analysis were collected at the indicated time points. The PK parameters were calculated by standard non-compartmental analysis.
Time frame: pre-dose, 1, 2, 3, 4, 8 and 24 hours post dose at Week 2
