Primary

MeasureTime frame
Main Objective: 1) To verify the safety of the study treatment, defined as the persistent control of the virus replication at 48 weeks after the simplification to lamivudine + atazanavir with ritonavir;Secondary Objective: To collect relevant informations about the safety and the metabolic impact of this strategy.;Primary end point(s): proportion of patients with virological failure (two consecutive HIV-RNA levels > 50 copies/mL or a single value >1000 copies/mL) within 48 weeks at intention-to.treat analysis
