The purpose of this study is to determine whether Recombinant Human Arginase 1 (rhArg1)is safe and effective in the treatment of patients with Relapsed or Refractory Leukemia or Lymphoma.
Further Study Information
This is a pilot, open-label study of PEG-BCT-100 in patients with relapsed/refractory leukemia or lymphoma who have satisfied all inclusion/exclusion criteria.
Approximately 15 subjects will be enrolled or when 10 evaluable subjects are included in the study. Evaluable subjects are defined as subjects who have received 4 consecutive doses of PEG-BCT-100 1600U/kg within 6 weeks from the first 1600U/kg dose and completed the first disease response assessment.
After the initiation of trial treatment, safety parameters will be evaluated throughout the study. Adverse event (AE) will be graded according to the National Cancer Institute Common Toxicity Criteria for Adverse Events version 4.0 (NCI CTC AE v4). AE and serious AE (SAE) will be detected and recorded on the Case Report Forms (CRFs) until 15-28 days after the last dose of PEG-BCT-100.
Patients who achieve complete remission (CR)/complete remission with incomplete blood count recovery (CRi) following the 4 consecutive 1600U/kg doses may continue PEG-BCT-100 at the discretion of the investigator.
Patients who achieve partial remission (PR) or stable disease (SD) following the 4 consecutive 1600U/kg doses can continue treatment up to disease progression. Further continuation will be determined by the clinical judgment of the Investigator. Patients who have disease progression will be discontinued PEG-BCT-100.
Blood samples for PK and PD analysis will be collected and analyzed.

- Male patient with sexual activity who does not agree to use adequate contraception (barrier method of birth control in conjunction with spermicidal jelly) prior to study entry and throughout the study.
- Use of any investigational drug(s) within 2 weeks prior to the start of the PEG-BCT-100.
- Use of any arginine depleting agent within 2 weeks prior to the start of the PEG-BCT-100.
- Subjects, who in the opinion of the Investigator, are unable to comply with the trial treatment and the related trial procedures.
