Participant Flow
Recruitment Details
| Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations |
|---|
| Participants were enrolled at 97 sites in the United States and 5 sites in Puerto Rico. The first participant was screened on 16 March 2010. The last participant observation for the Week 48 analysis was on 10 August 2011. |
Pre-Assignment Details
| Significant events and approaches for the overall study following participant enrollment, but prior to group assignment |
|---|
| 917 participants were screened; 707 were randomized (353 to the Stribild group and 354 to the Atripla group) of which 66.5% (470) had screening HIV-1 ribonucleic acid (RNA) ≤ 100,000 copies/mL. A total of 700 randomized participants received at least 1 dose of study medication and comprised the safety and intent-to treat (ITT) analysis sets. |
