E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate efficacy of GC33 vs. placebo through investigator-assessed progression-free survival (PFS) in patients with unresectable advanced or metastatic hepatocellular carcinoma (HCC) previously treated with at least 1 systemic agent, with documented progressive disease, or documented adverse event(s) resulting in discontinuance of that (those) agents, stratified by level of GPC-3 expression (IHC score) |

E.2.2 | Secondary objectives of the trial |
1. To compare treatment effect of GC33 vs. placebo on overall survival (OS)
2. To compare treatment effect of GC33 vs. placebo on disease control rate
3. To evaluate the tolerability and safety of GC33 when given as monotherapy in comparison to placebo using the NCI-CTCAE version 4.0
4. To further characterize the pharmacokinetic (PK) profile of GC33
5. To validate the GPC-3 immunohistochemistry(IHC) assay for analysis of GPC-3 expression

2. Known HCC with fibro-lamellar histology
3. Known brain or leptomeningeal metastases
4. Patients with a previous malignancy within the past 5 years are excluded(patients who had curatively treated basal cell carcinoma of the skin,early gastrointestinal cancer by endoscopic resection, and/or insitu carcinoma of the cervix and other malignancies which were considered cured and deemed by the PI to have no impact on the PFS and OS are allowed after discussion with the study medical monitor)
5. Active infectious diseases requiring treatment except for hepatitis B and C
6. NCI CTCAE version 4.0 grade 3 hemorrhage within 4 weeks of starting the study treatment
7. History of organ allograft including liver transplant
8. Anticipated or ongoing administration of anti-cancer therapies other than those administered in this study
9. Patient who have had any anticancer treatment within 2 weeks prior to entering the study
10. Patients who have not fully recovered from toxicities associated with previous HCC loco-regional or systemic therapies
11. Patients receiving Interferon therapy
12. Patients with baseline QTc > 470 ms, or patients with baseline resting bradycardia <45 beats per minutes.
13. Patients who received anticoagulation or thrombolytic agents for therapeutic purposes (except for low-dose administration for catheter clearance or for prophylactic purposes) within 2 weeks prior to Day 1
