Primary Outcome Measures:
  • Treatment Response at Week 48 [ Time Frame: At week 48 ]
    Treatment response (TR) is defined as two consecutive VL ≥ 1 log10 below baseline without discontinuation of study drug, change in anti-retroviral background, or rebound

  • Time to Treatment Failure Through 48 Weeks of Treatment [ Time Frame: Week 48 ]
    Time to treatment failure is defined as 0 for patients who never achieve TR otherwise time to treatment failure is the earliest time of death, discontinuation of the study drug or introduction of a new anti-retroviral drug to the regimen if it is not solely related to either toxicity or intolerance clearly attributable to a background, or the first of two consecutive visits with VL measurements <1 log10 below baseline.
