Summary:

      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.

          -  At least 2 documented plasma HIV-1 RNA <50 copies/mL and no HIV-1 >50 copies/mL in the
             12 months before screening

          -  Receiving the same protease inhibitor/ritonavir plus tenofovir/emtricitabine
