Induction-maintenance of Lopinavir/r in HIV-infected Subjects
Study ACA-ARGE-04-001 "A Pilot, Open-Label Study Assessing Safety, Tolerability, Efficacy of a Simplified Lopinavir/Ritonavir Induction/Maintenance Therapy in HIV-Infected Subjects on Their First Protease Inhibitor-Based Regimen".

This study will assess the safety, tolerability and antiviral activity of a simplified PI-based treatment regimen (Kaletra,ä) compared to conventional HAART regimens in patients infected with HIV-1 who are on their first boosted-PI antiretroviral treatment regimen.

The potency of the antiviral activity of Kaletra has been clearly demonstrated in a wide spectrum of patients in a number of different clinical trials.6-9 The durable viral suppression seen after 4 years of therapy10 proves that it can provide effective, long-term treatment for people with HIV-1.

Data from one of these trials (M97-720),6 an ongoing Phase II study of lopinavir/ritonavir in combination with NRTIs suggests there may be a role for monoclass therapy with Kaletra in the treatment of HIV-1-infection.

Phase 4
Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
HIV Infections
Drug: Lopinavir/ritonavir simplification strategy
Other Name: Kaletra monotherapy simplification strategy
  • Experimental: Lopinavir/ritonavir monotherapy
    Patients with undetectable viral load while on 1st line ARV therapy will be randomized to the expermental arm: Lopinavir/ritonavir monotherapy
    Intervention: Drug: Lopinavir/ritonavir simplification strategy
  • Active Comparator: Lopinavir/Ritonavir plus 2 NRTIs
    Patients randomized to this arm will continue with standard of care triple therapy, based on Lopinavir/Ritonavir plus 2 NRTIs
    Intervention: Drug: Lopinavir/ritonavir simplification strategy
