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 146 sites in 16 countries. The first participant was screened on 06 April 2010. The last participant observation for the Week 48 analysis was on 13 September 2011.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
1017 subjects were screened; 715 were randomized (357 to the Stribild group and 358 to the ATV/r + Truvada group) of which 61.4% (439) had screening HIV-1 ribonucleic acid (RNA) ≤ 100,000 copies/mL. A total of 708 randomized participants received at least 1 dose of study medication and comprised the safety and intent-to treat (ITT) analysis sets.
