Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of Participants Who Achieved HIV Ribonucleic Acid (RNA) <50 Copies/mL at Week 48 [ Time Frame: Week 48 ]
    Numbers of participants with HIV RNA copies <50 copies/mL were summarized by race for each time point.

  2. Number of Participants With One or More Adverse Events [ Time Frame: Week 48 ]
    Numbers of participants with one or more adverse events were summarized by race.

  3. Number of Participants Who Discontinued Due to an Adverse Event [ Time Frame: Week 48 ]
    Numbers of participants who discontinued due to an adverse event were summarized by race.


Secondary Outcome Measures :
  1. Number of Participants Who Achieved HIV RNA <400 Copies/mL at Week 48 [ Time Frame: Week 48 ]
    Numbers of participants with HIV RNA copies <400 copies/mL were summarized by race for each time point.

  2. Mean Change From Baseline to Week 48 in HIV RNA [ Time Frame: Baseline and Week 48 ]
    Mean changes from baseline in plasma HIV RNA were summarized by race at each time point.

  3. Mean Change From Baseline to Week 48 in CD4 Cell Count [ Time Frame: Baseline and Week 48 ]
    Mean changes from baseline in CD4 cell counts were summarized by race at each time point.

  4. Number of Participants Without Loss of Virologic Response [ Time Frame: Week 48 ]
    For participants with confirmed HIV RNA levels <50 copies/mL on 2 consecutive visits, loss of virologic response is the occurrence of the first value >50 copies/mL or loss to follow-up; participants who never achieved HIV RNA <50 copies/mL on 2 consecutive visits are also considered as having loss of virologic response. Events are the numbers of participants with loss of virologic response versus the numbers of participants with no loss of virologic response (event free).
