HIV Infections | Drug: Kaletra Tablets | Phase 3 |
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.

- Drug: Kaletra Tablets
Kaletra 800/200 OD
- 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
- 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
- To study compliance of subjects [ Time Frame: 48 weeks ]adherence assessed at each study visit
