Evaluation of Renal Function, Efficacy, and Safety When Switching From Tenofovir/Emtricitabine Plus a Protease Inhibitor/Ritonavir, to a Combination of Raltegravir (MK-0518) Plus Nevirapine Plus Lamivudine in HIV-1 Participants With Suppressed Viremia and Impaired Renal Function (MK-0518-284)

Switching From Regimens Consisting of a RTV-Boosted Protease Inhibitor Plus TDF/FTC to a Combination of Raltegravir Plus Nevirapine and Lamivudine in HIV Patients With Suppressed Viremia and Impaired Renal Function (RANIA Study) (Pilot Study) Protocol MK-0518-284-03

To evaluate changes in renal function, efficacy, and safety when switching from a combination of tenofovir/emtricitabine (TDF/FTC) plus a protease inhibitor/ritonavir (PI/r) to a combination of raltegravir (MK-0518) plus nevirapine plus lamivudine in human immunodeficiency virus (HIV)-1 infected participants with suppressed viremia and impaired renal function.
