研究概览
简要总结
Patients who completed the conventional treatment against HCV and relapsed (the virus appeared again in their blood) have no effective therapy.
详细描述
The rational behind the proposed study is that most patients can not tolerate the prolonged IFN injections because the side effects. The new proposed treatments allows continous low doses of IFN to be secreted by the patients himself using his own skin in which the dermo fibroblasts are enriched by a human gene of erythropoietin. The "biopump" continues to secret the IFN for several months avoiding the spikes of IFN in the plasma which are beleived to cause the undesired effects.
Patients will be able to complete a long treatment with low IFN dose and Ribavirin hoping to induce prolonged remission and cure

结局指标
主要结局
Safety and Efficacy of Sustained Interferon Alfa 2b (INF) Therapy of Relapsing Hepatitis C (HCV) Patients using InfraDure Biopump
时间窗: 9 months
All subjects will receive autologous InfraDure Biopump tissue implants intended to provide sustained production and delivery of therapeutic levels of INF for up to three (3) months following INFRADURE Biopump implantation, with possibility of extension for an additional six months for a total of 9 month post INFRADURE Biopump implantation. Saftey parameters (Adverse events and Serious Adverse Events as well as immediate and long term tolerability are the main safety parameters
