  • Arm comparisons: CD4 evolution, occurrence of HIV protease and RT mutation, occurrence of AIDS clinical events, safety of NRTI-sparing vs. a PI with 2 NRTIs regimen: clinical and biological tolerance, patient's adherence and quality of life. [ Time Frame: 48 weeks ]
  • To assess in the LPV/r single-drug regimen arm: virological control, CD4 evolution, safety [ Time Frame: 96 weeks ]

Efficacy and Safety of Kaletra Monotheraphy Compared to Kaletra Based Triple Therapy to Treat HIV in Antiretroviral Naїve Patients
A Pilot, Open-Label, Randomized, Comparative Study of the Antiviral Efficacy of Lopinavir/Ritonavir Single-Drug Regimen Versus Lopinavir/Ritonavir in Combination With Lamivudine/Zidovudine in Antiretroviral Naïve Patients
The purpose of this pilot study is to obtain a preliminary assessment of the antiviral activity and tolerability of Kaletra single agent therapy as initial treatment for HIV infection, relative to a Kaletra three drug standard of care reference arm
