4. Interferon treatment naïve: never received any interferon.

5. No other known form of chronic liver disease apart from chronic hepatitis C infection.

6. Hemoglobin 12 g/dL in men or 11 g/dL in women, white blood cell (WBC) count 3,000/mm3, absolute neutrophil count (ANC) 1,500/mm3, platelet count 90,000/mm3; and estimated glomerular filtration rate >60 mL/min.

7. Female and male subjects, and their partners of reproductive potential using effective means of contraception during the whole trial period.

8. Be able to attend all scheduled visits and to comply with all study procedures;

9. Be able to provide written informed consent.

Exclusion Criteria

1. Decompensated liver disease.

2. Clinically significant illness or surgery within 4 weeks prior to dosing.

3. Any reason which, in the opinion of the investigator, would prevent the subject from participating in the study.

4. Positive test for HBsAg or HIV at screening.

5. Clinically significant abnormal vital signs.

6. Evidence of severe retinopathy by fundoscopy except age-related macular degeneration.

7. Significant alcohol or illicit drug abuse within one year prior to the screening visit or refusal to abstain from excessive alcohol consumption as defined above or illicit drugs throughout the study.

8. Pregnant or breast feeding female subjects.

9. Therapy with any systemic anti-viral, anti-neoplastic, and immunomodulatory treatment.

10. Use of an investigational drug or participation in an investigational drug.

11. Known clinically significant presence of any gastrointestinal pathology, clinically significant unresolved gastrointestinal symptoms, clinically significant liver or clinically significant kidney disease, or other conditions known to interfere with the absorption, distribution, metabolism, or excretion of the drug.

12. Clinically significant presence of depression determined by investigators.

13. Clinically significant presence of severe neurological disorders.

14. Clinically significant presence of severe cardiovascular conditions and severe pulmonary conditions, uncontrolled immunologic, uncontrolled autoimmune, uncontrolled endocrine, uncontrolled metabolic, haematological, severe coagulation disorders or severe blood dyscrasias or other severe uncontrolled systemic disease.

15. A depot injection or an implant of any drug within 3 months prior to administration of study medication, other than contraception or hyaluronic acid injections in joints for osteoarthritis;

16. Body organ transplant and are taking immunosuppressants;

17. History of malignant disease, including solid tumors and hematologic malignancies. However, subjects who are cancer survivors not on maintenance therapy and who had no malignant diseases history within the past 5 years could be recruited.

18. History of or ongoing opportunistic infection.

19. Serious local infection or systemic infection.
