Arm Description
Pegylated human arginase (PA) in combination with Capecitabine (C) and Oxaliplatin (OX)
Outcomes
Primary Outcome Measures
The maximum tolerated dose (MTD) of Oxaliplatin (OX) in combination with PEG-BCT-100 (PA) and Capecitabine (C) in patients with locally advanced or metastatic hepatocellular carcinoma
There are 3 successive treatment cohorts in dose level of 85, 100 and 130 mg/m2 for Oxaliplatin. Subsequent treatment cohort is opened only after all patients in the previous cohort have completed the first 3 cycles of PACOX. At least 3 subjects will be treated at each cohort and observed for dose-limiting toxicity (DLT). If 1 of the 3 treated patients develops DLT at any dose level, 3 additional patients are to be entered at the same dose level. The dose of Oxaliplatin will be escalated if no DLT for the first 3 patients or 1 of the 6 treated patients develops a DLT. If 2 or more of the 3/6 patients at a given dose level experienced a DLT, dose escalation is stopped and the previous dose level is declared the MTD for the second part of the study. If the first 3 patients in Cohort 3 do not develop a DLT, an additional 3 patients will be enrolled in Cohort 3. If 1 or less than 1 patient in Cohort 3 has developed a DLT. the dose level is declared as the MTD.
Time To Progression (TTP)
TTP will be measured from the date of first dose of the PACOX regimen until documentation of disease progression according to RECIST 1.1 Criteria. Death due to cause other than progression will be censored. Patient without an event will be censored at date last known progression-free.
Secondary Outcome Measures
Progression free survival (PFS)
PFS will be measured as the start of the PACOX regimen until documentation of disease progression according to RECIST 1.1 Criteria or death due to any cause. Patients without an event will be censored at date last known progression-free
Overall Survival (OS)
OS is defined as the time form the start of PACOX regimen until death due to any cause, censored at the last date known alive.
Response Rate (RR)
The overall disease response rate in accordance with RECIST 1.1 Criteria, which is defined as the percentage of patients who achieve either a complete response (CR) or partial response (PR) or stable disease (SD)
Serum alpha-fetoprotein (AFP) level
change in serum AFP level from baseline.
To evaluate the difference in disease response based on RECIST 1.1 Criteria and modified RECIST Criteria
Safety events
Adverse Event (AE)/Serious AE evaluated by NCI CTCAE, version 4.0

5. Study Description
Brief Summary
The propose of the study is to evaluate the maximum tolerated dose (MTD) of Oxaliplatin in combination with pegylated recombinant human arginase 1 (PEG-BCT-100) and Capecitabine and efficacy of this combination regimen (PACOX)in patients with advanced liver cancer.
Detailed Description
This is a phase II open-label study. The first part of the study (Part 1) is a dose escalation study of a 21-day regimen of IV Oxaliplatin in combination with weekly IV PEG-BCT-100 2.7 mg/kg and oral Capecitabine 1000 mg/m2 twice per day for 14 days. There are 3 successive treatment cohorts in dose level of 85 mg/m2, 100 mg/m2 and 130 mg/m2 for Oxaliplatin. Subsequent treatment cohort is opened only after all patients in the previous cohort have completed the first 3 cycles of PACOX. The first patient entered the study is started at Cohort 1. At least three subjects will be treated at this cohort and observed for dose-limiting toxicity (DLT). If one of the three treated patients develops DLT at any dose level, three additional patients are to be entered at the same dose level. The dose of Oxaliplatin will be escalated if no DLT for the first three patients or one of the six treated patients develops a DLT. If two or more of the three/six patients at a given dose level experienced a DLT, dose escalation is stopped and the previous dose level is declared the MTD (recommended dose) of PACOX regimen for the second part of the study (Part 2). If the first three patients in Cohort 3 do not develop a DLT, an additional three patients will be enrolled in Cohort 3. If one or less than one patient in Cohort 3 has developed a DLT. the dose level is declared as the MTD.
Toxicity will be assessed through physical examination and vital signs findings, safety laboratory tests results, and graded by the NCI CTCAE (version 4.0).
Part 2: Patients receive the recommended dose of PACOX regimen as defined in Part 1. A 14-day screening period followed by a treatment period consisting of 3-week treatment cycles. Patients will be treated until disease progression or intolerable toxicity. The treatment period will end by a follow up visit at 30 days after the last dose of trial treatment. After the study treatment, patients will be follow-up every 8 weeks for survival status or until study termination.
Patients in both parts of the study will receive PACOX regimen until disease progression, intolerable toxicity, death or patients withdraw consent. The clinical effects of PACOX regimen on tumor response will be evaluated. Tumour assessment which is based on RECIST 1.1 criteria will be performed until disease progression.
