Study of Pegylated Human Recombinant Arginase for Liver Cancer
March 13, 2012 updated by: Bio-Cancer Treatment International Limited
Recombinant Human Arginase I (rhArgI) for Patients With Advanced Hepatocellular Carcinoma (HCC): An Adaptive Design Dose Escalation Trial With Addition of Standard Doxorubicin Treatment
The purpose of this study is to determine whether recombinant human arginase (PEG-BCT-100) is safe and effective in the treatment of advanced hepatocellular carcinoma (HCC).

Detailed Description
The primary objectives of this study are:
- To establish a safe dose level for weekly intravenous administration of PEG- BCT-100 (rhArgIpeg5000) based on clinical and laboratory safety assessments following a range of doses (from 500 to >5000 U/kg).
- To define the optimal biological dose (OBD) of PEG-BCT-100 based on the pharmacodynamics (PD) of arginine depletion (ADD) relative to plasma PK of PEG- BCT-100.
- To evaluate any objective tumor responses to PEG-BCT-100 in HCC patients receiving weekly doses of PEG-BCT-100 alone and in combination with standard doses of doxorubicin
Secondary objectives of this study are:
- To define any toxicities associated with the metabolic and cellular alterations of ADD relative to dose and PK of PEG-BCT-100 (rhArgIpeg5000).
- To develop a safe and biologically active dose and schedule for PEG-BCT-100 treatment in phase 2 trials, either as monotherapy or in combination with best standard of care chemotherapy.
- To confirm the safety and initial anti-tumor activity of the preferred dose and regimen of PEG-BCT-100 in 18 additional patients with advanced HCC
