   3. barrier methods (condom or diaphragm) with spermicide
   4. surgical sterilization of the partner (vasectomy for six months)
   5. hormonal contraceptives for at least three months prior to the first dose of study drug
10. Willing and able to comply with study procedures and provide written informed consent

Exclusion Criteria:

8. Eating disorder or alcohol abuse within the past two years, excessive alcohol intake (>20 g per day for females (1.5 standard alcohol drinks) or >30 g per day for males (2.0 standard alcohol drinks) (a standard drink contains 14 g of alcohol: 12 oz of beer, 5 oz of wine or 1.5 oz of spirits) (1.0 fluid oz (US) = 29.57 mL) or if in the opinion of the investigator, an alcohol use pattern that will interfere with study conduct

11. Abnormal TSH, T4 or T3

12. History or clinical evidence of any of the following:

    1. variceal bleeding, difficult to treat ascites, hepatic encephalopathy, CTP score >8,
    2. immunologically mediated disease (e.g, rheumatoid arthritis, inflammatory bowel disease, severe psoriasis, systemic lupus erythematosus) requiring more than intermittent non-steroidal anti-inflammatory medications for management or that requires frequent or prolonged use of corticosteroids (inhaled asthma medications are allowed)
    3. significant or unstable cardiac disease (e.g., angina, congestive heart failure, uncontrolled hypertension, history of arrhythmia)
    4. chronic pulmonary disease (e.g., chronic obstructive pulmonary disease) associated with functional impairment
    5. severe or uncontrolled psychiatric disease, including severe depression, history of suicidal ideation, suicidal attempts or psychosis requiring medication and/or hospitalization

14. Chronic use of concomitant drugs known to prolong the QT interval (See Appendix E)
15. Concomitant use of immunosuppressive or immune modulating agents
16. Patients with any serious 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
