Brief Summary
The general aim of this study is to determine if 3 MIU of IFN-α5 in monotherapy, and 1,5 MIU of IFN-α5 combined with 1,5 MIU of IFN- α2b, are safe dose levels as well as to investigate the antiviral efficacy and pharmacodynamics (PD) of such doses and drugs in treatment-experienced HCV patients with genotype 1 chronic infection, after 29 days of treatment. It is also intended to determine pharmacokinetics (PK) of the safe dose achieved of IFN-α5 in monotherapy.

Outcome Measures
Primary Outcomes (1)
Safe dose level
PRIMARY ENDPOINTS OF PHASE I * To determine if 3 MIU of IFN-α5 are well tolerated and if not, to find a safe dose level for IFN-α5. * To determine if 1.5 MIU of IFN-α5 in combination with 1.5 MIU of IFN-α2b (IFN-α5 + IFN-α2b) are well tolerated and if not, to find a safe dose level for the combination of IFN-α5 and IFN-α2b. PRIMARY ENDPOINTS OF PHASE II * To analyze IFN-α5 preliminary antiviral efficacy at the dose of 3 MIU, or the safe dose level identified in Phase I. * Primary safety endpoints: Occurrence of AE (classified into mild, moderate and severe)
29 days of treatment

Eligibility Criteria
You may qualify if:
- Patients aged ≥18 years old,
- With chronic hepatitis C (CHC) infection diagnosed by seropositivity for anti-HCV antibodies or detectable HCV-RNA, at least 6 months prior to screening.
- Patients with CHC infection of genotype 1 (1a, 1b or mixed 1a/1b)
- Defined as relapsers: those CHC patients who had achieved virologic response (HCV-RNA non detectable) at any time during the standard care of treatment for CHC with IFN-α2 or PegIFN-α2 + ribavirin, and maintained it trough the end of treatment at week 48 weeks, but HCV-RNA detection occurs before 6 months post-treatment.
- In whom liver cirrhosis has been ruled out through fibro-scan or liver biopsy within 24 months prior to study enrolment.
- With a serum HCV viral load ≥ 100.000 IU/mL at screening
- With alanine-aminotransferase (ALT) and aspartate-aminotransferase (AST) serum measurements at screening less than 5 times of their upper limits of normal (ULN)
- With a body mass index (BMI) of at least 18 kg/m2, but not exceeding 36 kg/m2.
- For female subjects with childbearing potential: use of a known highly effective method of birth control
- For male subjects with partners of child bearing potential: use of appropriate contraceptive methods.
- Is able to effectively communicate with the investigator and other testing center personnel.
- Is able to participate and willing to give written informed consent and comply with the study restrictions.
You may not qualify if:
- Hepatitis C infection of genotype 2, 3 or 4 or any mixed genotype (1/2, 1/3 and 1/4).
- A positive ELISA for HIV-1 or HIV-2.
- Hepatitis B virus (HBV) infection based on the presence of HBsAg.
- Hepatitis A virus (HAV) infection based on the presence of antiHAV-IgM. (AM 4)Criteria deleted
- Decompensated liver disease, or history of decompensated liver disease.
- History or other evidence of a medical condition associated with decompensated renal, immunologically mediated, chronic pulmonary, cardiac, thyroid, severe retinopathy, severe psychiatric, organ transplantation, cancer, seizure disorder or pancreatitis diseases.
- An active or suspected malignancy or history of malignancy within the last five years.
- Patients with a documented drug and alcohol addiction free history of at least 12 months who are, in the opinion of the investigator unlikely to relapse, may be enrolled in the study.
- Haemoglobin \<12.0g/dL for women, and \<13.0g/dL for men at screening.
