Purpose
This study examines the impact of fosamprenavir as part of an ART on virological, immunological and clinical parameters of genotype 1 HCV infection in HIV co-infected subjects. Fosamprenavir could have a direct or immune-mediated activity against HCV. If this is shown to be true, changes in HCV viral load or biological characteristics could be demonstrated.
| Condition | Intervention | Phase |
|---|---|---|
| Chronic HIV Infection HCV Coinfection | Drug: Fosamprenavir | Phase 4 |
| Study Type: | Interventional |
| Study Design: | Allocation: Randomized Intervention Model: Parallel Assignment Masking: None (Open Label) Primary Purpose: Treatment |
| Official Title: | Randomized, Controlled, Open Label, Pilot Study to Evaluate Fosamprenavir Activity on Genotype 1 Hepatitis C Virus (HCV) Infection Evolution in Human Immunodeficiency Virus (HIV) Co-infected Subjects With Antiretroviral Treatment Including Fosamprenavir |

Primary Outcome Measures:
- HCV Viral load and changes in HCV protease gene [ Time Frame: 48 weeks ]
Undetectable HCV viral load. It will be considered that one patient achieves this endpoint if he/she has an undetectable HCV viral load (<30 copies/mL) at any time during the study. If a patient shows undetectable HCV viral load and afterwards shows a detectable load, it will be considered that this patient achieved this endpoint.
Changes in the HCV protease gen. Any change from baseline in the protease catalytic domain, analysed by population sequencing of the catalytic domain of the HCV protease.
