Brief Summary
Objectives of the study:
- 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.
- 2.To collect relevant information about the safety and the metabolic impact of this strategy in order to eventually design a non-inferiority randomized controlled trial for the evaluation of the safety and the efficacy of this strategy in the future.
