"Pharmacoepidemiological Evaluation of Autophagy Inhibition in Treatment of HCV Patients Resistant to Standard Therapy. Pilot Study"

The purpose of this study is to assess the efficacy of Chloroquine comparing with placebo for treatment of non- response HCV patients.. In this triple blind pilot study, 20 patients with confirmed chronic hepatitis C will be randomize into treatment group (Chloroquine 150 mg daily, for 8 weeks) or control group (placebo once daily, for 8 weeks).

At the end of therapy (12 weeks) and at baseline, first, second and third month after receiving drug and placebo HCV Virus load, CBC LFT and biochemical parameters will be evaluated and compared between groups.

Inclusion Criteria:

• patients who failed to achieve a decline of 2 log HCV RNA IU/ml after 12 weeks of treatment
• who never achieved undetectable HCV RNA during treatment of a minimum duration of 24 weeks

Exclusion Criteria:
