Safety & Efficacy of Dual Therapy With Raltegravir/Lamivudine

Pilot 24week Clinical Trial to Assess the Safety, Tolerability and Efficacy of Dual Therapy With Raltegravir/Lamivudine Combination, Replacing Standard Combination Therapy in HIV-infected Pts With Prolonged Virological Suppression.

A pilot 24-week open-label, randomized, controlled clinical trial to assess the safety, tolerability and efficacy of dual therapy with Raltegravir/Lamivudine combination when replacing standard combination therapy in HIV-infected patients with prolonged virological suppression

4. Patients on combination antiretroviral therapy (at least 2 antiretroviral drugs) for at least 12 months before being randomized in this study.
5. Patients who are clinically stable in the opinion of the investigator at study entry (clinical status and chronic medication must not have not been modified at least 14 days prior to randomization).
6. Patients who have signed informed consent to participate in the study.

Exclusion Criteria:

1. Pregnancy, lactation, or planned pregnancy during the study period.
