Brief Summary:
The study has been designed to test the hypothesis that in patients co-infected with HIV and HCV who exhibit maximal virologic suppression on a double class antiretroviral (ARV) regimen, including two Nucleoside Reverse Transcriptase Inhibitors (NRTIs) and a Non-nucleoside Reverse Transcriptase Inhibitors (NNRTI) or a Protease Inhibitor (PI) (boosted or not with ritonavir), simplification of highly active antiretroviral therapy (HAART) to Kaletra® monotherapy will represent a viable strategy without any negative impact on the virologic control of HIV infection.

Condition or disease Intervention/treatment Phase
HIV Infections Drug: Kaletra Tablets Phase 3

Detailed Description:

The primary purpose of this study is to determine how safe and effective the drug Kaletra® is in treating HIV when it is administered without any other antiretroviral drugs (monotherapy). Kaletra® is 2 protease inhibitors (lopinavir and ritonavir) combined in one dosage form.

Kaletra monotherapy is experimental and subjects eligible to the study are switching from a successful conventional triple therapy to an unproven experimental therapy.

Approximately 40 HIV/HCV coinfected participants, aged over 18 years will participate in this study.

Intervention Details:
  • Drug: Kaletra Tablets
    Kaletra 800/200 OD

Primary Outcome Measures :
  1. The primary objective of this study is to assess the safety and efficacy of Kaletra® (lopinavir/ritonavir) monotherapy in the treatment of patients co-infected with HIV and HCV. [ Time Frame: 48 weeks ]
    patients on cART switched to Kaletra monotherapy an monitored for 48 weeks thereafter

Secondary Outcome Measures :
  1. To investigate and compare the pharmacokinetics (PK) of Kaletra® monotherapy at steady-state between co-infected subjects with advanced liver fibrosis (stage 3-4) and those with minimal liver disease (stage 0-2) [ Time Frame: 24 weeks ]
    PK measured at week 4 and 24

  2. To study compliance of subjects [ Time Frame: 48 weeks ]
    adherence assessed at each study visit
