Summary

Clearance of HCV infection requires early and multi-specific HLA class I restricted CD8+ T cell and class II restricted CD4+ T cell responses to both structural (Core) and non-structural HCV proteins (NS3, NS4A, NS5A, NS5B). Dendritic cells (DCs) are professional antigen-presenting cells that link innate and adaptive immune responses, and play a major role in priming, initiating, and sustaining strong anti-HCV T cell immune responses.

The general objective of this study is to evaluate safety, feasibility and clinical efficacy of therapeutic vaccination in genotype 1 HCV patients using autologous DCs pulsed with recombinant HCV-antigens (Core and NS3). Expected effects: DC vaccination induces Core/NS3-specific immune response and reduces viral load in patients with chronic HCV-infection.

Conditions

Interventions

BIOLOGICAL

Autologous DC-vaccines

Patients will be vaccinated via intracutaneous injection of autologous DCs (5×106) combined with adjuvant subcutaneous injection of recombinant hIL-2 (250 000 IU). Initiating course: one vaccination per week, during 1 month. Maintaining course: one vaccination per month, during 6 month. Patients will be monitored in a 2 months (after completing of initiating course), 7 months (after completing of maintaining course) and 13 months (in a 6 months post-vaccination follow-up).
