Date de début de l'étude : 21 juin 2018

INCLUSION CRITERIA * Be 18 years of age or older. * Be able to understand and provide written informed consent or have a legally authorized representative (LAR). * Have an Eastern Cooperative Group (ECOG) performance status \< 2 (please see the appendix). * Have documentation of histologically confirmed adenocarcinoma. Biopsy must have been completed prior to start of treatment; additional biopsy is not required for the study. * Have clinical stage consistent with resectable or borderline resectable adenocarcinoma of the pancreas, based on CT or MRI findings. * Have adequate organ and bone marrow function, as defined by: * total leukocytes \>3 x10\^3/μL. * absolute neutrophil count (ANC) \>1.5x 10\^3/μL. * hemoglobin \>9 g/dL. * platelets \>100 x 10\^3/μL. * creatinine clearance \>60 mL/min or creatinine \<1.5 mg/dL; bilirubin \< 2 mg/dL. * aspartate transaminases (AST/SGOT) and alanine transaminases (ALT/SGPT) \<3 x upper limit of normal (ULN). At two weeks from biliary decompression, if the subject's serum AST/ALT remains greater 3x ULN, but has demonstrated a progressive decline, the subject may be enrolled into the trial and appropriate modification and dose adjustments will be made to the assigned regimen. Eligibility of subjects whose AST/ALT remain elevated 3x ULN, without demonstrating a downward trend, will be determined at the discretion of the trial principal investigators. * Subjects must be CA19-9 producers as defined by a pretreatment CA 19-9 \> 35 U/mL, when total bilirubin \<2 mg/dL. * Female patients must be postmenopausal (absence of menses for \> 1 year), surgically sterile, or have a negative pregnancy test and use at least one form of contraception for four weeks prior to Day 1 of the study, during study treatment and during the first four months after study treatment is discontinued. Male patients must be surgically sterile or use barrier contraception during the study and for four months after the last dose of any study drug. EXCLUSION CRITERIA * Has received more than two months of FOLFIRINOX or mFOLFIRINOX chemotherapy as first-line therapy. * No documentation of a CA19-9 value when total bilirubin \< 2 prior to initiation of chemotherapy. * Has received any additional chemotherapy and/or radiation within three years prior to study enrollment. * Has any previous history of another malignancy (other than cured basal or squamous cell carcinoma of the skin or cured in situ carcinoma of the cervix or localized prostate cancer with normal prostate specific antigen) within three years of study enrollment. * Uncontrolled comorbidities including, but not limited to, ongoing or active serious infection, symptomatic congestive heart failure, unstable angina, unstable cardiac arrhythmias, psychiatric illness, excessive obesity (BMI \>55) or situations that would limit compliance with the study requirements or the ability to willingly give written informed consent. * Known human immunodeficiency virus (HIV), hepatitis B virus (HBV) or hepatitis C virus (HCV) infection. * Pregnant or breastfeeding patients or any patient with childbearing potential not using contraception four weeks prior to treatment.
