Trial Information

A Phase I, Open-Label, Multi-center, Dose-escalation Study of the Safety, Tolerability, and Pharmacokinetics of GC33 in Combination With Sorafenib (Nexavar®) in Patients With Advanced or Metastatic Hepatocellular Carcinoma (HCC).

This is a Phase I open-label dose escalation study of GC33 in combination with Sorafenib in
patients with advanced or metastatic HCC. This study is designed to evaluate safety,
tolerability, pharmacokinetics, and efficacy. Enrollment will proceed until a maximum
tolerated dose (MTD) and a recommended Phase II dose has been established.

- Not a candidate for curative treatments.

- Child-Pugh A

- Hematological, Biochemical and Organ Function:

- AST (SGOT): ≤5.0 × ULN,

- ALT (SGPT): ≤5.0 × ULN,

- Total Bilirubin: ≤1.5mg/dL,

- Platelets: ≥100,000/μL,

- Absolute Neutrophil Count: ≥1,500/μL,

- Serum creatinine: ≤2.0 × ULN,

- PT-INR: ≤2.0

- Ability to provide a tumor tissue sample either by:

- A formalin fixed paraffin embedded block sample within 12 months prior to
informed consent for HCC diagnosis

- Undergo a biopsy to confirm HCC diagnosis

- Measurable disease.

Exclusion Criteria:

- Child-Pugh B or C

- Patient who have taken Sorafenib previously.

- Difficulty or inability to swallow pills.

cell transplantation, etc.).

- Uncontrolled intercurrent illness including, but not limited to, ongoing or active
infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
arrhythmia, or psychiatric illness/social situations that would limit compliance with
study requirements..

- Patients with known brain metastases or other central nervous system

- Uncontrolled hypertension defined as systolic blood pressure >150 mmhg or diastolic
blood pressure >90 mmHg, despite optimal medical management.

- Non-tumor related thrombolic or embolic events such as a cerebrovascular accident
including transient ischemic attacks within the past 6 months.

- Pulmonary hemorrhage/bleeding event ≥ CTCAE Grade 3, any other hemorrhage/bleeding
event ≥ CTCAE Grade 4 within 4 weeks of first dose of study drug.

- Serious non-healing wound, ulcer, or bone fracture.

- Patients who received major surgery, local therapy for HCC, chemotherapy,
radiotherapy, hormone-therapy, immunotherapy, or another investigational drug within
4 weeks prior to Day 1(6 weeks for nitrosoureas, mitomycin, and bevacizumab; 1 week
for tumor biopsy).

- Patients who received the following treatments within 2 weeks prior to Day 1:

- Anticoagulant or thrombolytic agents for therapeutic purposes,

- Systemic anti-viral therapy for hepatitis C and Interferon therapy for hepatitis

- Blood transfusion including all blood products

- Known history of hypersensitivity to similar agents.

- Patients receiving any medications or substances that are inducers of CYP3A4 are
ineligible: rifampin, St. John's wort, phenytoin, carbamazepine, phenobarbital and

- Any psychological, familial, sociological or geographical condition potentially
hampering compliance with the study protocol requirements and/or follow-up
procedures; those conditions should be discussed with the patient before trial entry.
