Brief Summary

Management of participants with low-level persistent viremia

Detailed Description

ANRS 161 L-Vir is a phase III prospective, randomized, multicenter, open-label, superiority trial for participants with low-level persistent viremia.

Participants will be randomized with a 1:1:1 ratio to the following three arms,

* Reference arm : counseling without antiretroviral treatment modification

* Switch arm : switch of current PI/r for Prezista® (darunavir)/ Norvir® (ritonavir) (switch for a drug with a higher genetic barrier) 600/100 mg two times a day (BID) with counseling.

* Addition of Isentress® (raltégravir) arm : Isentress® (raltegravir) 400 mg two times a day (BID) added to current antiretroviral treatment with counseling
