Study Details

Study Description

Brief Summary

Three-parallel-arm, open-label, international (France and Romania) study, comparing three treatments

The purpose of this study is to confirm if IFN alfa-2b XL has a better antiviral activity and tolerability as compared with current marketed reference, while combined with ribavirin, in a 3-month therapy setting.

Condition or Disease Intervention/Treatment Phase
  • Drug: IFN alfa-2b XL 27 MUI + Ribavirin
  • Drug: IFN alfa-2b XL 36 MUI + Ribavirin
  • Drug: IFN peg alfa-2b 1.5 µg/kg + Ribavirin
Phase 2

Detailed Description

Interferon alfa-2b XL (IFN alfa-2b XL) is a novel sustained release interferon α-2b drug product that is being developed by FLAMEL TECHNOLOGIES using its Medusa® technology, aiming at reducing the toxicity and enhancing the biological response. In the present study, patients will be randomly assigned to either IFN alfa-2b XL 27 MUI, IFN alfa-2b XL 36 MUI, or IFN peg alfa-2b 1.5 µg/kg, all administered once a week for 12 weeks by subcutaneous injections, in combination with weight dosed ribavirin daily administered orally in two divided doses. Doses will be adapted according to the dose modification guidelines for combination therapy labelled in the ribavirin prescribing information.

Outcome Measures

Primary Outcome Measures

  1. Viral load decrease at Week 4 and Week 12 of treatment with IFN alfa-2b XL 27 MIU, IFN alfa-2b XL 36 MIU and the marketed reference product (PEG IFN alfa-2b 1.5μg/kg) in combination with ribavirin [Week 4 and Week 12]

Secondary Outcome Measures

  1. Percentage of patients with early virologic response (EVR) (reduction of at least 2 log viral load) at the end of week 12 [Week 4 and Week 12]

  2. Percentage of patients with complete early virologic response (EVR) (viral load <15 IU) at the end of the week 12 [Week 4 and Week 12]
