History of Changes
  Purpose

The study is being done with people who are taking their first anti-HIV drug regimen (including an Non-Nucleoside Reverse Transcriptase Inhibitor (NNRTI), a type of anti-HIV drug) but the drugs in this regimen are not doing a good job of fighting their HIV infection.

The main purpose of this study is to compare two other anti-HIV drug regimens to see how well they fight HIV. The study will also see how well participants tolerate the drug regimens and how safe they are.

The study will determine whether taking the combination of lopinavir/ritonavir (LPV/r) plus raltegravir (RAL) works as well as what usually is used for second-line therapy: LPV/r plus the best-available nucleoside (nucleotide) reverse transcriptase inhibitor (NRTI) combination. Testing a regimen that does not include any NRTI is important because NRTIs may no longer work for patients who received them as part of their first treatment regimen.

Primary Outcome Measures:
  • Time to virologic failure [ Time Frame: At or after study Week 24 ] [ Designated as safety issue: No ]
    The primary endpoint is time to virologic failure. Virologic failure is defined as confirmed viral load >400 copies/mL at or after week 24.


Secondary Outcome Measures:
  • Change in CD4+ cell count from baseline [ Time Frame: Weeks 48 and 96 ] [ Designated as safety issue: No ]
    CD4+ cell count at baseline, weeks 48, 96 and at virologic failure

  • HIV-1 drug resistance mutations in gag, protease, reverse transcriptase, and integrase in participants with virologic failure at baseline and at time of virologic failure [ Time Frame: Through to week 96 ] [ Designated as safety issue: No ]
  • Time to first Grade 3 or higher Adverse Event (AE) that is at least one grade higher than baseline [ Time Frame: Through to week 96 ] [ Designated as safety issue: Yes ]
  • Time to discontinuation of randomized treatment for toxicity [ Time Frame: Through to week 96 ] [ Designated as safety issue: Yes ]
    Time to discontinuation of randomized treatment for toxicity (including participant decision to discontinue for low grade toxicity); within class NRTI changes are not considered an endpoint.

  • Time to new AIDS-defining events, death and targeted serious non-AIDS-defining events [ Time Frame: Through to week 96 ] [ Designated as safety issue: Yes ]
  • Duration of hospitalizations [ Time Frame: Through to week 96 ] [ Designated as safety issue: No ]
  • Changes in fasting total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, and glucose from baseline [ Time Frame: Weeks 48 and 96 ] [ Designated as safety issue: No ]
