Brief Summary:
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).

Condition or disease Intervention/treatment Phase
Neoplasm Hepatocellular Carcinoma Biological: Pegylated Recombinant Human Arginase I Phase 1 Phase 2

Detailed Description:

The primary objectives of this study are:

  • To evaluate any objective tumor responses to PEG-BCT-100 in HCC patients receiving weekly doses of PEG-BCT-100 alone.
  • To perform PK and PD analysis
  • To measure Quality of Life of the patients

Secondary objectives of this study are:

  • To define any toxicity associated with the metabolic and cellular alterations of ADD relative to dose and PK of PEG-BCT-100 (rhArgIpeg5000).
  • To confirm the safety and anti-tumor activity of PEG-BCT-100 at the preferred dose (1600U/kg) in 50 patients (at least 18 evaluable subjects) with advanced HCC.
  • To measure duration of response including Overall Survival and Time to Progression analysis

Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Recombinant Human Arginase I (rhArgI) for Patients With Advanced Hepatocellular Carcinoma (HCC)
Study Start Date : March 2010
Actual Primary Completion Date : February 2012
Actual Study Completion Date : February 2012

Arm Intervention/treatment
Experimental: PEG-BCT-100
Pegylated Recombinant Human Arginase I
Biological: Pegylated Recombinant Human Arginase I
Weekly dose of PEG-BCT-100 for at least 8 weeks (or until disease progression) at 1600U/kg
Other Name: PEG-BCT-100

Primary Outcome Measures :
  1. Tumor response [ Time Frame: 12 weeks ]
    Tumor response endpoints include(a)Objective response for each patient evaluated by RECIST, (b)Modified RECIST criteria will be used as secondary reference, (c) The proportion of patients achieving a partial response or complete response (d) The proportion of patients reporting disease progression by RECIST and the times to progression (e)Serial changes in plasma AFP levels after doses of PEG-BCT-100 and (f)Change in relevant viral serology from baseline to end-of-study

Secondary Outcome Measures :
  1. Overall Survival [ Time Frame: 12 weeks ]
    Overall Survival measurement from the date of starting the first dose of PEG-BCT-100 until death from any cause at every 4 weeks until the patient's death, or 3 months from the last patient's study visit, through clinical visits or telephone follow-ups

  2. Time to Progression [ Time Frame: 12 weeks ]
  3. Plasma arginase level [ Time Frame: 12 weeks ]
    The PK endpoints include (a) Dose-related peak to trough concentrations of plasma PEG-BCT-100 over time (b)Plasma clearance of PEG-BCT-100; and(c)Intra- and inter-subject variability of plasma PK parameters to assess the predictability of PEG-BCT-100 administration

  4. Quality of Life [ Time Frame: 12 weeks ]
    Measurement of Quality of Life by completing 2 questionnaires at baseline, week 8 and 4-weekly after week 8 until end of treatment visit. The Chinese version of the EORTC QLQ-C30 will be used, which contains Five functional scales and Three symptom scales. The Chinese version of EORTC QLQ-HCC18 will also be used.

  5. Plasma arginine levels [ Time Frame: 12 weeks ]
    The PD endpoints include (a)The magnitude of plasma arginine depletion relative to the dose (b)The duration of effective ADD assessed by plasma arginine <8 µM relative to the plasma peak and time to clearance (c) The relationships of PEG-BCT-100 dose and its resultant effective ADD to changes in AFP and/or tumor symptoms and measurements(d)The temporal and quantitative relationships of depleted plasma arginine to dose and plasma concentrations of PEG-BCT-100; and (e)Correlation of prolonged arginine depletion with extended survival
