Study of Pegylated Human Recombinant Arginase for Liver Cancer (BCT-100-002) (BCT-100-002)

Recombinant Human Arginase I (rhArgI) for Patients With Advanced Hepatocellular Carcinoma (HCC)

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).

Study Overview

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

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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
12 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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
12 weeks
Time to Progression
Time Frame: 12 weeks
12 weeks
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
12 weeks
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.
12 weeks
