Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Participants with human immunodeficiency virus – type 1 (HIV-1) infection were enrolled in this study from DUET Study TMC125-C206 or TMC125-C216 and met the definition of virologic failure at Week 24 or later in these studies, or who completed one of the DUET studies after 96 weeks of treatment.

Reporting Groups
  Description
DUET PLACEBO Participants who received Placebo in a previous DUET study and received open-label treatment with 200 mg twice daily etravirine, also known as TMC125 (ETR) and 600/100 mg twice daily darunavir (DRV)/low-dose ritonavir (rtv) were referred to as ETR-naïve participants.
DUET TMC125 Participants who received etravirine, also known as TMC125 (ETR) in a previous DUET study and received open-label treatment with 200 mg twice daily ETR and 600/100 mg twice daily darunavir (DRV)/low-dose ritonavir (rtv) were referred to as ETR-experienced participants.

Measure Type Secondary
Measure Title The Percentage of Participants With Virologic Outcomes Over Time
Measure Description The table below shows the percentage of participants with virologic suppression (< 50 copies/mL), the percentage of participants who were virologic failures (VF) (>50 copies/mL, discontinued prior to time X for reasons of VF or for other reasons, except for VF or adverse event, with a last viral load >50 copies/mL), and the percentage of participants with no viral load (VL) data available over time (ie, at Weeks 24, 48, and 96).
Time Frame Weeks 24, 48, and 96  
Safety Issue No  

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
The intent-to-treat (ITT) population was used as the primary analysis population for the efficacy analysis and included all participants who took at least one dose of etravirine (ETR) (also known as TMC125) in the TMC125-C217 study.
