Brief Summary:

This study will compare a nucleoside reverse transcriptase inhibitor-sparing (NRTI-sparing) regimen (Kaletra + nevirapine) to two nucleoside reverse transcriptase inhibitor-based regimens (Combivir + nevirapine and Combivir + Kaletra).

Participants will be randomly assigned to receive one of the following drug combinations:

  • lopinavir/ritonavir (Kaletra) and nevirapine (Viramune) twice a day;
  • Combivir (Zidovudine (AZT) plus lamivudine (3TC)) and nevirapine twice a day;
  • Combivir and lopinavir/ritonavir twice a day.

Condition or disease Intervention/treatment Phase
HIV Mitochondrial Toxicity Drug: lopinavir/ritonavir; nevirapine; Zidovudine; Lamivudine Phase 4

Primary Outcome Measures :
  1. Changes in mitochondrial DNA/Nuclear DNA (mtDNA/nDNA) ratio at 48 weeks, as a marker of mitochondrial toxicity. [ Time Frame: 48 weeks ]

Secondary Outcome Measures :
  1. Changes in mitochondrial DNA/Nuclear DNA (mtDNA/nDNA) ratio at 96 weeks [ Time Frame: 96 weeks ]
  2. Proportions of patients with viral load below 50 and below 400 copies/mL
  3. Viral load changes from baseline
  4. Rates and extent of immune reconstitution (CD4 count increase)
  5. Rates and severity of dyslipidemia and insuline resistance/diabetes
