Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Subjects recruited between February 2008 and May 2011 from participating ACTG, IMPAACT, and ATN network sites located in the continental US and Puerto Rico.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
A total of 104 exclusions among 517 enrolled to active screening but prior to assignment and dispensation of study treatment were due to any of the following: no resistance/tropism test results, not willing to accept any ARV study regimens, changes to current PI based ARV regimen or non-adherence, or changes with respect to eligibility criteria.

Reporting Groups
  Description
Add NRTIs (Randomized) to Individualized Regimen (cPSS > 2.0) [Arm A]Individualized ARV study regimen with antiretroviral potency defined as continuous phenotype sensitivity score (cPSS) greater than 2.0 recommended and chosen prior to randomization. To this regimen, an individualized NRTI combination of at least 2 drugs from this class, chosen prior to randomization, was also started.
Omit NRTIs (Randomized) From Individualized Regimen(cPSS > 2) [Arm B] Individualized ARV study regimen with antiretroviral potency defined as continuous phenotype sensitivity score (cPSS) greater than 2.0 recommended and chosen prior to randomization. To this regimen, an individualized NRTI combination of at least 2 drugs from this class, chosen prior to randomization, was omitted, and any NRTIs the participant had been taking prior to randomization were to be permanently discontinued.
Non-randomized Group: Add NRTIs to Individual Regimen cPSS <=2 [Non-randomized Group C] : Among persons whose ARV resistance and history profile precluded any of the 20 possible ARV regimens having high enough potential potency (cPSS <=2), treatment was assigned rather than being a randomized. To their regimen, individualized NRTI combination of at least 2 drugs from this class were added in order to form the most potent ARV regimen possible.
