This phase I/II is studying the side effect and best dose of Z-208 for patients with advanced hepatocellular carcinoma

This is an open-label, dose-escalation study PhaseI Treatments repeats for 28 days for 1 course in the unacceptable toxicity

Cohort of 3 patients receive escalating doses of Z-208 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 1 of 3 patients experience dose-limiting toxicity.

PhaseII Treatments repeats for 28 days for 6 courses until absence of disease progression or unacceptable toxicity.
