Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
The study was approved in 10/2007. HIV-infected individuals 18 years of age receiving stable, suppressive antiretroviral therapy (ART) with persistent plasma HIV-1 RNA level of > 0.6 copies/mL by single-copy assay at screening; enrollment started in in 12/2007 at the University of Pittsburgh Clinical Trials Unit from 12/2007 through 1/2009.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Participants had Cluster of Differentiation 4(CD4) counts of greater than 200 cells/microliter, HIVRNA< 50 copies/mL plasma for ≥12 months; and not receiving prophylaxis for opportunistic infections (OI)s; no history of exposure to raltegravir, HIV-1 drug resistance,febrile illness within 3 weeks or vaccination within 6 weeks before enrollment.
