About this trial

This is an interventional treatment trial for Hepatitis C focused on measuring HCV, Hepatitis C, Hepatitis

Eligibility Criteria

18 Years - 55 Years (Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Males or females, 18 to 55 years of age who are diagnosed with HCV by PCR

  • Chronic hepatitis C infection, genotype 1 or genotype 2, two documented tests (PCR or HCV Ab; if one of the tests is HCV Ab, then the second test must be PCR and the PCR test must be at least 6 months after the HCV Ab test) at least 6 months apart

  • Females of childbearing potential (intact uterus and within 1 year since the last menstrual period) should be non-lactating and have a negative serum pregnancy test. In addition, these subjects should agree to use one of the following acceptable birth control methods throughout the study:

  • History or clinical evidence of any of the following:

    1. variceal bleeding, ascites, hepatic encephalopathy, CTP score >6, decompensated liver disease or any other form of non-viral hepatitis
    2. immunologically mediated disease (e.g., rheumatoid arthritis, inflammatory bowel disease, severe psoriasis, systemic lupus erythematosus) requiring more than intermittent nonsteroidal anti-inflammatory medications for management or that requires frequent or prolonged use of corticosteroids (inhaled asthma medications are allowed)
    3. any malignancy within 3 years except for basal cell skin cancer
    4. significant or unstable cardiac disease (e.g., angina, congestive heart failure, uncontrolled hypertension, history of arrhythmia)
    5. chronic pulmonary disease (e.g., chronic obstructive pulmonary disease) associated with functional impairment
    6. severe or uncontrolled psychiatric disease, including severe depression, history of suicidal ideation, suicidal attempts or psychosis requiring medication and/or hospitalization
  • Patients with a body mass index >30 kg/m2
  • Concomitant drugs known to prolong the QT interval (see Appendix E)
  • Concomitant use of immunosuppressive or immune modulating agents
  • Patients with any serious or condition that, in the opinion of the investigator, would preclude evaluation of response or make it unlikely that the contemplated course of therapy and follow-up could be completed or increase the risk to the subject of participation in the trial

    5. Study Description

    Brief Summary
    The purpose of this study is to test the hypothesis that clemizole hydrochloride is safe and well tolerated when administered to subjects who are infected with hepatitis C virus and have not yet received treatment. This study will also examine how the virus and body respond to clemizole hydrochloride.
    Detailed Description
    This study is a phase 1b, open label study of four weeks of treatment with 100 mg po BID of clemizole hydrochloride administered immediately prior to the initiation of treatment with HCV standard of care therapy consisting of pegylated interferon and ribavirin in treatment-naïve subjects chronically infected with HCV genotype 1 or genotype 2. The duration of the study for each subject will be approximately 11 weeks (up to three week screening period, four week treatment period and four week safety follow-up period). The duration of the entire study is anticipated to be approximately four months (first subject in to last subject out). Pharmacokinetic sampling will be done at Day 1 and Day 28 of dosing. PK sampling will be conducted only on subjects who have consented to participate in the PK portion of this study. Participation in PK sampling is optional for each subject.
