  • Documented diagnosis of HCC that has been completely resected or ablated (RFA or MVA only)
  • Absence of major macrovascular invasion (except Vp1/Vp2) and extrahepatic spread
  • Absence of extrahepatic spread as confirmed by CT or MRI scan of the chest, abdomen, pelvis, and head prior to and following curative procedure
  • Full recovery from surgical resection or ablation within 4 weeks prior to randomization
  • High risk for HCC recurrence after resection or ablation
  • For patients who received post-operative transarterial chemoembolization: full recovery from the procedure within 4 weeks prior to randomization
  • For patients with resected HCC, availability of a representative baseline tumor tissue sample
  • ECOG Performance Status of 0 or 1
  • Child-Pugh Class A status
  • Adequate hematologic and end-organ function
  • For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods
