Must have measurable lesion(s) per RECIST version 1.1 by CT scan with contrast (or MRI, if the patient is allergic to CT contrast media). NOTE: Bone disease consisting of blastic lesion only is not measurable. 7. Archival or fresh tumor tissue must be available for evaluating relevant biomarkers. Formalin-fixed paraffin-embedded [FFPE] block preferred, or a minimum of 10 unstained FFPE slides of one archived block is required. NOTE: Cytology samples from fine needle aspirates or brushing biopsies are not sufficient. 8. Must have adequate performance status: 1. ECOG Performance Status (PS) score of 0, or 2. ECOG PS score one and score ≥80 on Karnofsky Performance Status (KPS) scale. NOTE: Must have body mass index (BMI) ≥18.5 kg/m2 (obtained <14 days prior to randomization. 9. Must have life expectancy of >12 weeks according to the investigator's clinical judgment. 10. Females of childbearing potential must have a negative pregnancy test at screening and additional negative pregnancy test prior to first dose. Males and females of childbearing potential must agree to use a highly effective method of contraception during treatment and for at least 6 months after the last dose of study treatment. 11. Must have adequate laboratory parameters at baseline (obtained <14 days prior to randomization). Laboratory parameters outside of these ranges that are deemed clinically insignificant should be discussed with the medical monitor: 1. Absolute neutrophil count ≥1.5 x 109/L. 2. Hemoglobin ≥9 g/dL. Patients with a baseline Hemoglobin ≥13 g/dL should be discussed with the medical monitor. 3. Platelet count ≥100,000/mm3 (100 x 109/L). 4. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤2.5 x upper limit of normal (ULN) (≤5 x ULN in presence of liver metastases). 5. Total bilirubin ≤ 1.5 x institutional ULN. 6. Serum creatinine within normal limits or calculated clearance >60 mL/min/1.73 m2 for patients with serum creatinine levels above or below the institutional normal range. 7. Acceptable coagulation parameters: plasma antithrombin III >70%, fibrinogen ≥1.5 g/L, international normalized ratio (INR) <1.5, and partial thromboplastin time (PTT) ≤ institutional ULN. 8. Serum albumin ≥3.0 g/dL. 12. Patients requiring biliary stent placement must have the biliary stent placed >7 days prior to screening and must have normalization of bilirubin level after stenting. 13. Must not be receiving therapy in a concurrent clinical study and must agree not to participate in any other interventional clinical studies during their participation in this trial while on study treatment. Patients taking part in surveys or observational studies are eligible to participate in this study. 14. Must be able to understand and comply with the conditions of the protocol and must have read and understood the consent form and provided written informed consent. Exclusion Criteria: A patient is not eligible to participate in the study if any of the following criteria are met: 1. Resectable or borderline resectable pancreatic adenocarcinoma at the time of signing the informed consent. 2. Histology other than pancreatic adenocarcinoma (for example, but not inclusive: neuroendocrine, adenosquamous, etc.). 3. More than one line of prior treatment in advanced or metastatic setting. 4. Patient has experienced medically significant acute decline in clinical status including 1. Decline in ECOG PS to >1 (or KPS <70) between baseline visit and within 72 hours prior to randomization. 2. Weight loss of ≥10% during screening. 5. Presence of active or symptomatic untreated central nervous system (CNS) metastases. NOTE: Patients with asymptomatic or stable CNS metastases are eligible, provided that the CNS metastases are radiologically and clinically stable, and the patient is off high-dose steroid treatment for at least one month prior to randomization. 6. Prior radiotherapy to the only area of measurable disease. NOTE: Patients must have completed treatment and recovered from all acute treatment-related toxicities prior to administration of the first dose of eryaspase or chemotherapy. 7. Bone as the only site of metastatic disease from pancreatic cancer (bone only disease). 8. History of recent clinical pancreatitis, according to revised Atlanta criteria, within 3 months of randomization. NOTE: The revised Atlanta classification  requires that two or more of the following criteria be met for the diagnosis of acute pancreatitis: (a) abdominal pain suggestive of pancreatitis, (b) serum amylase or lipase level ≥3 x ULN, or (c) characteristic imaging findings using CT or MRI. 9. Neurosensory neuropathy > Grade 2 at baseline. 10. Pregnancy or breastfeeding. 11. History of infection with human immunodeficiency virus (HIV) and/or active infection with hepatitis B or hepatitis C. NOTE: Patients with unknown status of hepatitis B or C must be tested and declared negative before randomization. 12. Hypersensitivity to any of the components of the chemotherapy or ASNase. 13. Patients who have received live or live attenuated vaccines within 3 weeks of randomization. 14. History of other malignancies NOTE: Adequately treated non-melanoma skin cancer or curatively treated in-situ cancer of the cervix may be eligible. NOTE: Patients successfully treated for other malignancies and are disease-free for at least 5 years may be eligible. 15. Any other severe acute or chronic condition/treatments that may increase the risk of study participation including: 1. History of abdominal fistula, gastrointestinal perforation, peptic ulcer, or intra-abdominal abscess within 6 months prior to randomization. 2. Current or history within 6 months prior to randomization of medically significant cardiovascular disease including symptomatic congestive heart failure >New York Heart Association (NYHA) Class II, unstable angina pectoris, clinically significant cardiac arrhythmia. 3. Patients with pre-existing coagulopathy (e.g. hemophilia). 4. Psychiatric illness/social situations or any other serious uncontrolled medical disorders in the opinion of the Investigator that would limit compliance with study requirements.
District of Columbia
Patients who meet all inclusion and exclusion criteria will be randomized in a 1:1 ratio to one of the following treatment arms (see figure below): - Arm A (investigational arm): eryaspase in combination with either gemcitabine/Abraxane or irinotecan-based therapy (FOLFIRI [FOLinic acid-Fluorouracil-IRInotecan regimen] or Onivyde®/5 fluorouracil/leucovorin), or - Arm B (control arm): gemcitabine/Abraxane or irinotecan-based therapy (FOLFIRI or Onivyde/5-FU/leucovorin) The chemotherapy will be investigator's choice and based on what patient has received in first line treatment. Treatment will continue until disease progression, unacceptable toxicity, or the patient's withdrawal of consent. An End of Treatment visit should occur within approximately 30 days from last dose of eryaspase or chemotherapy regimen. A survival follow-up period will include the collection of survival, progression of disease if applicable, treatment updates, and quality of life assessments every 8 weeks.
