Safety and Efficacy of Sustained Interferon Alfa 2b (INF) Therapy of Relapsing Hepatitis C (HCV) Patients Using InfraDure Biopump
Safety and Efficacy of Sustained Interferon Alfa 2b (INF) Therapy of Relapsing Hepatitis C (HCV) Patients Using InfraDure Biopump
Patients who completed the conventional treatment against HCV and relapsed (the virus
 appeared again in their blood) have no effective therapy.
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
Inclusion Criteria:

 -  Signed patient consent form

 -  Chronic HCV patients in relapse following conventional treatment regimen
 (INF+Ribavirine) with detectable plasma level of HCV RNA

 -  Hepatitis B and human immunodeficiency virus negative at screening visit

 -  Able and willing to follow contraception requirements

 -  Screening laboratory values, test, and physical exam within acceptable range

 Exclusion Criteria:

 -  Current enrollment in another investigational device or drug study

 -  Anticipated inability to complete all clinic visits and comply with study procedures

 -  History of, or any current medical condition, which could impact the safety of the
 subject during the study

 -  Autoimmune hepatitis, suspected hepatocellular carcinoma, decompensated liver disease,
 or other known liver disease other than HCV

 -  Alcoholism or substance abuse with <6 documented months of sobriety

 -  Known allergy or sensitivity to interferons or ribavirin

 -  Any other condition that, in the opinion of the Investigator, would make the subject
 unsuitable for enrollment or could interfere with the subject participating in and
 completing the study
