Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Study participants were recruited from 22 U.S. sites from April 2009 to August 2009.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Study participants were HIV-1-infected, antiretroviral(ARV)-naive men and women, 18 years and older with plasma HIV-1 RNA >= 5000 copies/ml. One enrolled participant never started study treatment.
