Study of ADI-PEG 20 Versus Placebo in Subjects With Genotype WWOX-GG, Unresectable HCC
Study Details
Study Description
Brief Summary
Evaluate efficacy and safety of ADI-PEG 20 in patients with genotype WWOX-GG and HCC
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
|
Phase 3 |
Detailed Description
Safety will be evaluated by laboratory tests, vital sign measurements, physical examinations and subject medical history which will be performed to detect new abnormalities and any deterioration in pre-existing conditions.
Efficacy will be determined by overall survival, progression free survival, pharmacodynamics (peripheral blood arginine and citrulline levels) and immunogenicity (antibodies to ADI-PEG 20).

Eligibility Criteria
Criteria
Inclusion Criteria:
-
Prior diagnosis of HCC confirmed by radiology, histology, or cytology.
-
Prior treatment with at least 1 systemic agent for Child-Pugh A subjects. However, Child-Pugh B7 subjects without prior systemic treatment may be enrolled, if they are not eligible for any approved systemic therapies.
-
WWOX genotype GG.
-
Measurable disease using RECIST 1.1. At least 1 measurable lesion must be present.
-
Child-Pugh (cirrhosis status) score class A-B7.
-
Barcelona Cancer of the Liver (BCLC) stage C.
-
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 at enrollment.
-
Expected survival of at least 3 months.
-
Age >20 years.
-
Fully recovered from prior surgery, radiation, or chemotherapy, and none within 2 weeks prior to week 1 visit. Liver biopsy for HCC confirmation is allowed.
-
Female subjects and male subjects must be asked to use appropriate contraception for both the male and female for the duration of the study and for 35 days after last dose of ADI-PEG 20. Male partners of female subjects and female partners of male subjects must agree to use two forms of contraception or agree to refrain from intercourse for the duration of the study if they are of childbearing potential. Females of childbearing potential must not be pregnant at the start of the study, and a serum human chorionic gonadotropin (HCG) pregnancy test must be negative before entry into the study. If positive HCG pregnancy test, further evaluation to rule out pregnancy must be performed according to GCP before this subject is deemed eligible. Females not of childbearing potential must be post-menopausal (defined as cessation of regular menstrual period for at least 12 months).
-
Informed consent must be obtained prior to study initiation.
-
No concurrent investigational studies are allowed.
-
Total bilirubin < 3.0 mg/dL and no evidence of bile obstruction.
-
Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤5 x upper limit of normal range.
-
Serum albumin level ≥ 3.0 g/dl.
-
Prothrombin time (PT)-international normalized ratio (INR): PT <3 seconds above control or INR <1.7.
-
Absolute neutrophil count (ANC) >1,500/μL.
-
Platelets >50,000/μL.
-
Serum uric acid ≤ 8 mg/dL (with or without medication control).
-
Serum creatinine ≤ 1.5 x the upper limit of normal range, or, if serum creatinine >1.5 x the upper limit of normal range, then the creatinine clearance must be ≥ 40 mL/min.
-
Subjects with active hepatitis B or C on anti-viremic compounds may remain on such treatment, except for interferon.
-
Encephalopathy - none or mild (grade 1 or 2, by Child-Pugh classification); lactulose of other supportive care allowed.
-
Ascites - absent or slight (by Child-Pugh classification); diuretic therapy allowed
Exclusion Criteria:
-
Candidate for potential curative therapies (i.e., resection or transplantation) or eligible for approved systemic therapies according to the labeling of such drugs.
-
Prior allograft transplantation including liver transplantation.
-
Subjects who have not fully recovered from toxicities associated with previous HCC loco-regional or systemic therapies, except for Grade 1 alopecia.
-
Serious infection requiring treatment with systemically administered antibiotics at the time of study entrance, or an infection requiring systemic antibiotic therapy within 7 days prior to the first dose of study treatment.
-
Pregnancy or lactation.
-
Expected non-compliance.
-
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure (New York Heart Association Class III or IV), cardiac arrhythmia, or psychiatric illness, social situations that would limit compliance with study requirements.
-
Subjects with history of another primary cancer, including co-existent second malignancy, with the exception of: a) curatively resected non-melanoma skin cancer; b) curatively treated cervical carcinoma in situ; or c) other primary solid tumor with no known active disease present or in the opinion of the investigator will not affect patient outcome.
-
Subjects who had been treated with ADI-PEG 20 previously.
-
History of uncontrolled seizure disorder not related to underlying cancer.
-
Allergy to pegylated compounds.
-
Allergy to E. coli drug products (such as GMCSF).
-
Bleeding esophageal or gastric varices within the prior three months, except if banded or treated.
-
Uncontrolled ascites (defined as not easily controlled with diuretic treatment).
-
Having received any blood transfusion, blood component preparation, erythropoietin, albumin preparation, or granulocyte colony stimulating factors (G-CSF) within 7 days prior to screening laboratories or after screening laboratories have been obtained until week 1 visit.
-
Eastern Cooperative Oncology Group (ECOG) performance status ≥ 2.
