This is a phase 1b/2 study to evaluate the safety and efficacy of NANT-008 in combination
with 5-fluorouracil, bevacizumab, leucovorin, and oxaliplatin in patients with metastatic
Phase 1b is designed to evaluate the recommended phase 2 dose (RP2D) of NANT-008 and
dose-limiting toxicities (DLTs) of NANT-008 in combination with metronomic 5-FU, bevacizumab,
leucovorin, and oxaliplatin in subjects with advanced metastatic pancreatic carcinoma. In
phase 2, subjects will receive the combination of RP2D of NANT-008 from phase 1b in
combination with metronomic 5-FU, bevacizumab, leucovorin, and oxaliplatin. Phase 2 is
designed to evaluate the efficacy of the tested regimen as assessed by 1-year survival rate
in subjects with advanced metastatic pancreatic adenocarcinoma.

evidence of disease; prior history of prostate cancer that is not under active
systemic treatment (except hormonal therapy) and with undetectable PSA (< 0.2 ng/mL).

4. Hemoglobin < 9 g/dL.
5. Total bilirubin greater than the upper limit of normal (ULN) at time of
enrollment; unless the subject has known history of Gilbert's syndrome.
6. Aspartate aminotransferase (AST [SGOT]) or alanine aminotransferase (ALT [SGPT])
> 2.5 × ULN (> 5 × ULN in subjects with liver metastases).
7. Alkaline phosphatase levels > 2.5 × ULN (> 5 × ULN in subjects with liver
metastases, or >10 × ULN in subjects with bone metastases).
8. Serum creatinine > 2.0 mg/dL or 177 μmol/L.
9. International normalized ratio (INR) or activated partial thromboplastin time
(aPTT) or partial thromboplastin time (PTT) >1.5 × ULN.
4. Pre-existing peripheral neuropathy > grade 1 based on NCI CTCAE V4.03.
5. Dihydropyrimidine dehydrogenase gene polymorphism (DPYD*2A) (must be tested prior to

corticosteroids (dose equivalent to or greater than 10 mg/day methylprednisolone),
excluding inhaled steroids. Short-term steroid use to prevent IV contrast allergic
reaction or anaphylaxis in subjects who have known contrast allergies is allowed.
7. Positive results of screening test for human immunodeficiency virus (HIV), hepatitis B
virus (HBV), or hepatitis C virus (HCV).

biopsy for diagnosis without removal of an organ), within 4 weeks prior to day 1 of
treatment in this study or surgical wound has not fully healed.

10. Evidence of gastric ulcers, gastrointestinal fistulas, and gastrointestinal
11. History of interstitial lung disease, history of slowly progressive dyspnea and
unproductive cough, sarcoidosis, silicosis, idiopathic pulmonary fibrosis, pulmonary
hypersensitivity pneumonitis or multiple allergies that in the opinion of the
Investigator may put them at increased risk of interstitial pneumonitis.

clinically significant (ie, active) cardiovascular disease, cerebrovascular
accident/stroke, or myocardial infarction within 6 months prior to first study
medication; unstable angina; congestive heart failure of New York Heart Association
