The present study aims to compare efficacy, side-effects, and treatment adherence of three different treatment regimens given to antiretroviral naïve HIV-1 infected patients. Treatment will be initiated in accordance with the Swedish National Guidelines. In the twice daily (BID) arm (1), which could be considered as a standard regimen at present, lopinavir/ritonavir, is co-administrated with 2 nucleoside reverse transcriptase inhibitors (NRTIs) administrated BID. The first once daily (QD) arm (2) combines the protease inhibitor (PI) atazanavir/ritonavir with 2 NRTIs administrated QD, and in the second QD arm (3), the non nucleoside reverse transcriptase inhibitor (NNRTI) efavirenz is combined with 2 NRTIs administrated QD. All drugs used in the study are licensed in the participating countries and patients will be followed as in clinical practice. Patients could optionally, after informed consent, be followed with additional measurements of HIV-1 RNA after 1, 2, and 3 weeks of treatment to asses the kinetics of viral decline after initiation of treatment.

Primary Outcome Measures:
  • Intention to treat (ITT)/time to loss of virological response (TLOVR) [ Time Frame: 144 weeks ]
    1. Virological failure (see 5.5.2 for definition)
    2. Treatment interruption or change of study treatment due to side-effects
    3. Treatment interruption or change of study treatment due to any other reason
    4. Missed to follow-up

    1. HIV-1 RNA >50 copies/ml in two consecutive measurements from week 24 and on 2. any rise in HIV-1 RNA >50 copies/ml in two consecutive measurements after viral load <50 copies/ml has been reached 3. HIV-1 RNA never <50 copies/ml after week 24

Secondary Outcome Measures:
  • Frequency of abnormal laboratory parameters [ Time Frame: 144 weeks ]
    Incidence of abnormal laboratory parameters at follow-up

  • Adherence to study medication [ Time Frame: 144 weeks ]
    Proportion of doses taken correctly

  • Frequency of adverse events [ Time Frame: 144 weeks ]
    Proportion of treatment discontinuations and changes due to different adverse events

  • Changes in CD4 cell counts [ Time Frame: 144 weeks ]
    Changes in CD4+ T-cell count from baseline

  • Changes in plasma lipids [ Time Frame: 144 weeks ]
    Changes from baseline in plasma lipids

  • Frequency of hyperlipidemia [ Time Frame: 144 weeks ]
    Incidence of hypercholesterolemia and hypertriglyceridemia at baseline and follow-up
