Brief Summary:
This study is designed to evaluate the safety of biological active dose of a new experimental drug, IL-7, in combination with standard bi-therapy in Asiatic patients with Hepatitis C chronic infection identified as non responders to the standard bi-therapy alone.

Condition or disease Intervention/treatment Phase
Hepatitis C Drug: Interleukin-7 Phase 1 Phase 2

Detailed Description:

This is a Phase I/IIa inter-patient dose-escalation study assessing weekly doses of Interleukin-7 (CYT107) in Asiatic adult patients infected by virus of genotype 1 of Hepatitis C and resistant to standard treatment with Peg-Interferon and Ribavirin (bi-therapy).

The dose escalation is aimed at establishing the safety of a biologically active doses of CYT107 added to the combination therapy of pegylated interferon-alpha and ribavirin. At each dose level, study patients will receive one subcutaneous administration of CYT107 per week for a total of 4.

Groups of 3 to 6 patients will be entered at each dose level of CYT107. Three dose levels are planned.

Eligible patients initially receive bi-therapy for 6-10 weeks. Thereafter, CYT107 is added for a cycle of four weekly injections at a defined dose level while standard bi-therapy continues for 9 weeks after CYT107 treatment discontinuation. The patients are then followed on a regular basis until reaching 48 weeks after the CYT107 treatment. The duration of study is approximatively 60 weeks with 20-25 weeks of bi-therapy.

Participants will have 1 overnight hospitalization and 15 clinic visit on a period of 60 weeks.

During the visits the following may be done:

  • medical history, physical examination, blood tests
  • electrocardiograms (ECG)
  • chest X-Ray
  • liver/spleen imaging
  • urine tests

Arm Intervention/treatment
Experimental: CYT107 Drug: Interleukin-7
3 dose levels: 3, 10 & 20 µg/kg. 4 administrations, 1 per week

Primary Outcome Measures :
  1. safety of biologically active doses of CYT107 added to a combination therapy by pegylated interferon-alpha and ribavirin in Asian patients with a chronic infection by a genotype 1 HCV not responding to this combination therapy [ Time Frame: 12 weeks after start of CYT107 ]

Secondary Outcome Measures :
  1. Pharmacokinetics and pharmacodynamics of CYT107 in this patients population. [ Time Frame: At short and mid terms follow-ups ]
  2. potential anti-viral effect of CYT107 [ Time Frame: 4 weeks and 12 weeks after start of CYT107 ]
  3. long-term safety and viral load variations [ Time Frame: 24 and 48 weeks after the start of CYT107 ]
  4. immune specific response to HCV [ Time Frame: 8 and 12 weeks after start of CYT107 ]
