Brief Summary

A phase IV, prospective, multicenter , randomized open label, 48 weeks study to evaluate the antiretroviral efficacy and safety of atazanavir/ritonavir or darunavir/ritonavir, each in combination with a fixed dose of tenofovir disoproxil fumarate- emtricitabine in HIV-1-infected treatment-naïve subjects with CD4 counts below 200 µL.

Detailed Description

Principal objective

To evaluate the virological efficacy and safety at week 48 of 2 regimens atazanavir/ritonavir (ATZ/r) 300/100 mg or darunavir/ritonavir (DRV/r) 800/100 mg, each in combination with a fixed-dose of tenofovir/emtracitabine in HIV-1 treatment-naïve subjects with CD4 counts below 200 µL.

Secondary objectives

• Proportion of subjets with virologic efficacy at week 24
• Proportion of subjects with confirmed virologic failure at week 24 or later
• Proportion of patients with virologic mutations
• Evaluate the virologic effect in seminal fluid
• To evaluate immunological response over time up to week 48
• To assess plasma and seminal pharmacokinetics of the drugs in the treatment regimen at week 4, 24, and 48
• Correlate the pharmacokinetic properties of the drugs with virologic outcome in plasma and semen at week 4 and 48
• Correlate the free fraction (not bound to protein) of atazanavir and darunavir in plasma and semen to virologic outcome
• Evaluate the relationship of bilirubinemia with atazanavir
• Change from baseline in fasting lipids, fasting glucose and insulin over time in the 2 arms
• Compare adherence patient satisfaction and sexual behaviour between the regimens
