6. Contraception: Female subjects of childbearing potential must use ≥1 effective method of contraception during the study and until 30 days following the last dose of investigational product. Effective methods of contraception are considered to be the following: barrier method, ie, condom (male or female) with spermicide or diaphragm with spermicide, intrauterine device, vasectomy (partner), hormonal (eg, contraceptive pill, patch, intramuscular implant or injection), abstinence (defined as refraining from heterosexual intercourse).

4. LDL cholesterol >200 mg/dL at any Screening Visit in subjects who are not on statin therapy, or at Screening Visit 2 in statin washout subjects.
5. Planned change in diet or exercise habits during participation in the double-blind period, or a significant weight change of >5% in the prior 6 months.
6. Subjects who have undergone gastric bypass procedures (gastric lap band is acceptable) or ileal resection or plan to undergo either of these procedures.
7. History of biliary diversion
8. Uncontrolled diabetes defined as HbA1c ≥9.5% within 60 days prior to randomization (Day 1).

     • other cytokines or chemokines

10. Evidence of other forms of chronic liver disease including but not limited to:

11. History of liver transplant, current placement on a liver transplant list, or current Model for End-Stage Liver Disease (MELD) score >12. Subjects who are placed on a transplant list despite relatively early disease stage (eg, per regional guidelines) may be eligible as long as they do not meet any of the other exclusion criteria
