Comparison of Treatment Simplification by LPV/r vs Current Treatment Continuation in HIV-Infected Patients

Phase 3
Completed
Conditions
HIV Infections
Interventions
Drug: Lopinavir/ritonavir (drug)
Registration Number
NCT00140751
Lead Sponsor
Institut de Médecine et d'Epidémiologie Appliquée - Fondation Internationale Léon M'Ba
Brief Summary

The purpose of this study is to compare the efficacy and tolerance of a treatment simplification by a Lopinavir/ritonavir monotherapy versus continuation of current treatment in HIV-infected patients

Detailed Description

Highly active antiretroviral therapy (HAART) has made a significant impact on the natural history of HIV-1 infection, but toxicities and complexities of therapy limit long-term efficacy, and make simpler yet effective HAART regimens highly desirable. Previous attempts to 'de-intensify' protease inhibitor (PI)-based therapy by discontinuing reverse transcriptase inhibitors (RTI) after achieving viral suppression met with failure, probably because plasma levels of most individually administered PI are too low to inhibit viral replication consistently.

Low-dose ritonavir substantially enhances lopinavir plasma levels, and lopinavir/ritonavir (LPV/r) is effective as part of a combination therapy in both naive and PI-experienced patients. Furthermore, lopinavir is known to have a high genetic barrier to selection of resistance. LPV/r monotherapy could thus have the right combination of potency, favorable pharmacokinetics, and high genetic barrier needed to suppress viral replication and prevent the selection of lopinavir resistance. Preliminary results with "maintenance"LPV/r monotherapy show interesting results but data from randomized studies are needed.
