Primary Outcome Measures:
  • Percentage of Participants Experiencing Any Treatment-Emergent Study Dug-Related Adverse Event [ Time Frame: Up to Week 408 plus 30 days ]

Secondary Outcome Measures:
  • Percentage of Participants Experiencing Treatment-Emergent Adverse Events [ Time Frame: Up to Week 408 plus 30 days ]
    Adverse events (AEs) occurring during treatment and for 30 days following the last dose of study drug were summarized across the participant population. A participant was counted once if they had a qualifying event.

  • Percentage of Participants Experiencing Any Treatment-Emergent Laboratory Abnormality [ Time Frame: Up to Week 408 plus 30 days ]
    Treatment-emergent laboratory abnormalities were defined as values that increase at least one toxicity grade from baseline. The most severe graded abnormality from all tests was counted for each participant.

  • Percentage of Participants Experiencing Any Marked Treatment-Emergent Laboratory Abnormality [ Time Frame: Up to Week 408 plus 30 days ]
    A 'marked abnormality' was defined as a shift from grade 0 (or missing) at baseline to at least grade 3 postbaseline; or grade 1 at baseline to grade 4 postbaseline.

Experimental: EVG+RTV

EVG 85 mg or 150 mg + RTV + ARV regimen

Participants receiving lopinavir/ritonavir (LPV/r) or atazanavir/ritonavir (ATV/r) as part of their ARV regimen will receive EVG 85 mg and all other participants will receive EVG 150 mg.

Some participants may receive EVG 300 mg during the course of protocol amendment 2.
