E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to assess the effect on viral load of IPH1101 administered in monotherapy or in association with a low dose of IL2 (2 MIU) in naïve hepatitis C patients. |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives are to: - Confirm the safety profile of the dose regimen in this population - Assess the impact on viral load clearance kinetics (timing and duration of antiviral response) of IPH1101 alone or in association with a low dose of IL2 - Evaluate the biological activity: Gamma Delta T cells amplification, cytokines release, and soluble antiviral factors release (such as Serum neopterin, beta2 microglobulin) after IPH1101 in monotherapy or in association with IL2.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint will be the viral load. Serum HCV RNA will be evaluated by a standardized reverse-transcription PCR. Viral load will be assessed by quantitative HCV RNA detection. Efficacy for this exploratory proof of concept study will be defined by response corresponding to a diminution of ½ log in viral load from baseline on at least one blood sample over 12 weeks. |
