Official Title

* Drug: Darinaparsin


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria HCC diagnosed by histology or clinical evidence supported by liver mass(es) at least 2cm in the longest diameter and AFP equal to or more than 500 ng/mL in cirrhosis or chronic HBV or HCV infection27. Male or female patients ≥ 18 years of age Patients who have a life expectancy of at least 12 weeks Patients who have at least one uni-dimensional measurable lesion by CT-scan or MRI according to Response Evaluation Criteria in Solid Tumors (RECIST). Patients who have an Eastern Co-operative Oncology Group (ECOG) performance status of 0 - 2 (see Appendix 4). Patients who have received local therapy, such as surgery, radiation therapy, hepatic arterial embolization, chemo-embolization, radio-frequency ablation or cryo-ablation are eligible, provided that they either have a target lesion which has not been subjected to local therapy and/or the target lesion(s) within the field of the local therapy has shown an increase of ≥ 25% in the size. Furthermore, the local therapy applied to target or non-target lesions needs to have been completed at least 8 weeks prior to study inclusion. Lesions treated with external beam radiation therapy are not acceptable as target lesions, unless they fulfil the conditions described above. No more than one prior chemotherapy based regimen is allowed. Patients can receive up to two regimes where target therapies have been used (washout) Cirrhotic status of Child-Pugh Class A or B only (Appendix 5). Adequate hepatic function at screening as assessed by the following: Platelet count ≥ 60 x 109/L Hemoglobin ≥ 8.5 g/dl Total bilirubin ≤ 3 mg/dl ALT and AST ≤ 5 x upper limit of normal Serum creatinine ≤ 2.0 x the upper limit of normal PT-INR ≤ 2.3 or PT ≤ 6 seconds above control Patients who give written informed consent prior to any study specific screening procedures with the understanding that the patient has the right to withdraw from the study at any time, without prejudice. Exclusion Criteria Previous malignancy (except for cervical carcinoma in situ, adequately treated basal cell carcinoma, or superficial bladder tumors [Ta, Tis and T1] or other malignancies curatively treated > 2 years prior to entry) Congestive heart failure > NYHA Class II Cardiac arrhythmias requiring anti-arrythmics (excluding beta blockers or digoxin for chronic stable atrial fibrillation) or QTc greater than 450 msec. Active coronary artery disease or cardiac ischemia Active clinically serious bacterial, viral or fungal infections (> grade 2 NCI-CTCAE, Version 3) Known history of human immunodeficiency virus (HIV) infection for less than 2 years or uncontrolled disease on antiretroviral medication Metastatic brain or meningeal tumors Patients with seizure disorder requiring medication (such as anti-epileptics) History of confusion or dementia or neurological condition that could mask a potential adverse response to the study drug (or something along these lines) History of organ allograft Substance abuse, medical, psychological or social conditions that may interfere with the patient's participation in the study or evaluation of the study results Known or suspected allergy to the investigational agent or any agent given in association with this trial Any condition that is unstable or which could jeopardize the safety of the patient and his/her compliance in the study Pregnant or breast-feeding patients. Women of childbearing potential must have a negative pregnancy test performed within 14 days prior to the start of study drug. Both men and women enrolled in this trial must use adequate barrier birth control measures during the course of the trial
