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.

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.
ITT analysis set. The missing = excluded (M = E) method was used in which all participants with missing data were excluded from analysis.

The agreement is:

The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is less than or equal to 60 days. The sponsor cannot require changes to the communication and cannot extend the embargo.

The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is more than 60 days but less than or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.

Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed.

Restriction Description:

After conclusion of the study and without prior written approval from Gilead, investigators in this study may communicate, orally present, or publish in scientific journals or other media only after the following conditions have been met:
