Virological response is defined as confirmed plasma viral load less than (<) 50 human immunodeficiency virus-1 (HIV-1) (ribonucleic acid [RNA]) copies/milliliter (ml) at Week 48. The TLOVR algorithm was used to derive response. Response needed to be confirmed at 2 consecutive visits and participants who permanently discontinued were considered nonresponders after discontinuation. Resuppression after confirmed virologic failure was considered as failure. Virologic Failure includes participants who were rebounder (confirmed viral load >= 50 copies/ml after being responder) or who were never suppressed (no confirmed viral load <50 copies/ml).

The Intent-to-Treat analysis set was considered the primary efficacy analysis set.

The analysis is based on the last observed viral load (VL) data within the Week 48 window. Virologic response is defined as a VL<50 copies/mL (observed case). Missing VL was considered as non-response. Virologic Failure includes subjects who had VL>=50 copies/mL in the Wk 48 window, subjects who discontinued early due to lack or loss of efficacy, subjects who discontinued for reasons other than an adverse event, death or lack or loss of efficacy and at the time of discontinuation had a VL>=50 copies/mL and subjects who had a switch in background regimen that was not permitted by the protocol.

Virological response is defined as (observed) plasma viral load less than 50 human immunodeficiency virus-type 1 (HIV-1) ribonucleic acid (RNA) copies per mL at the last on-treatment post-Week 96 visit.

Participants with at least 1 Post-Week 96 visit were included in the analysis.

Virological response is defined as confirmed plasma viral load < 400 HIV-1 (RNA) copies/mL at Week 48. The TLOVR algorithm was used to derive response. Response needed to be confirmed at 2 consecutive visits and participants who permanently discontinued were considered nonresponders after discontinuation. Resuppression after confirmed virologic failure was considered as failure. Virologic Failure includes participants who were rebounder (confirmed viral load >= 400 copies/mL after being responder) or who were never suppressed (no confirmed viral load <400 copies/mL).

Change from baseline in CD4+ cell count was imputed in case of missing values: in case of premature discontinuation, data were imputed with the baseline value after discontinuation (i.e. change=0, Non-Completer [NC] = Failure); otherwise last observation carried forward was applied.

The Intent-to-Treat analysis set was considered the primary efficacy analysis set.

Virologic failure for the resistance determinations was defined as lack of virologic response (never having had 2 consecutive plasma viral load <50 copies/mL) and plasma viral load increase of >=0.5 log 10 copies/mL above nadir (i.e., never suppressed), or confirmed loss of virologic response (2 consecutive plasma viral load >=50 copies/mL after having had 2 consecutive plasma viral load <50 copies/mL; i.e., rebounder), or discontinued with a last observed on-treatment plasma viral load >=50 copies/mL after having had 2 consecutive plasma viral load <50 copies/mL. For this study, treatment-emergent reverse transcriptase (RT) resistance associated mutations (RAMs) occurring in at least 2 virologic failures (for at least one treatment group) for the following lists are presented: i) Extended list of Non-nucleoside reverse transcriptase inhibitor (NNRTI RAMs) ii) IAS-USA list of Nucleoside/tide reverse transcriptase inhibitor (N[t]RTI RAMs).

The Intent-to-Treat analysis set was considered the primary efficacy analysis set. Here "N" (Number of Participants Analyzed) signifies number of Participants who were evaluable (had data) for this outcome.
