  Purpose

The purpose of this study is to evaluate if HIV-1 infected subjects who are virologically suppressed on a regimen which consists of 2 Nucleoside reverse transcriptase inhibitor's (NRTI) plus any 3rd agent but who are experiencing safety and/or tolerability issues to this regimen will continue to maintain virologic suppression following a switch to a regimen consisting of heat-stable Ritonavir boosted Atazanavir (300/100mg) once daily plus Raltegravir (400mg) twice daily.

Primary Outcome Measures:
  • Proportion of subjects with HIV-1 Ribonucleic acid (RNA) < 40 c/mL through week 24 as measured by quantitative HIV RNA Reverse Transcriptase-Polymerase chain reaction (RT-PCR). [ Time Frame: Week 24 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Proportion of subjects with HIV-1 RNA < 40 c/mL. [ Time Frame: Week 48 ] [ Designated as safety issue: No ]
  • Safety as measured by the frequency of Serious Adverse Events (SAEs), the frequency of Adverse Events(AEs), frequency of AEs leading to discontinuation, the frequency of lab abnormalities and by changes from baseline in fasting lipids. [ Time Frame: Week 24 ] [ Designated as safety issue: Yes ]
  • Safety as measured by the frequency of SAEs, the frequency of AEs, frequency of AEs leading to discontinuation, the frequency of lab abnormalities and by changes from baseline in fasting lipids. [ Time Frame: Week 48 ] [ Designated as safety issue: Yes ]
  • Incidence of resistance and characterization of this resistance following a virological rebound [ Time Frame: Week 24 ] [ Designated as safety issue: No ]
  • Incidence of resistance and characterization of this resistance following a virological rebound [ Time Frame: Week 48 ] [ Designated as safety issue: No ]
