Inclusion Criteria:
* Subjects with imaging suggesting resectable pancreatic cancer and without strong evidence of metastatic disease.

* Adequate bone marrow and organ function
* Subjects of childbearing potential must have a negative urine or serum pregnancy test prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required for enrollment.
* Subjects of child-bearing potential must agree to use adequate contraception E.g. hormonal , barrier method of birth control, and abstinence prior to study entry, for the duration of study treatment, and for 6 months after completion of study therapy. Subject who become pregnant or suspect they are pregnant while they or their partner is participating in this study, they should inform their treating physician immediately. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with the study therapy, subjects should agree to discontinue breastfeeding prior enrollment in the study.
* As determined by the enrolling physician or protocol designee, ability of the subject to understand a written informed consent document, and ability and willingness to comply with study procedures for the entire length of the study. Patients with impaired decision-making capacity (IDMC) who have a close caregiver or legally authorized representative (LAR) and/or family member who can make may decision on the patient behalf may enroll in the trial per the enrolling physician assessment.
Exclusion Criteria:
* Patients with borderline or locally advanced or metastatic pancreatic cancer as deemed by treating surgeon.
* Patients who are unlikely to undergo surgery, and systemic therapy, in the opinion of the treating investigators.
* Patients with grade ≥ 2 peripheral neuropathy.
* Patients with known Gilbert's Syndrome, Dihydropyrimidine dehydrogenase (DPD) deficiency, or homozygosity for UGAT1A1\*28 polymorphism. Note: evaluation for these is not required.
* Patients with active duodenal or gastric ulcers, or direct tumor invasion of the bowel or stomach by endoscopic evaluation. Note: patients with previous ulcers without active bleeding or symptoms are eligible.
* Patients with serious active infection within 2 weeks prior to enrollment (e.g. requiring hospitalization and/or intravenous \[IV\] antibiotics) or currently receiving oral or IV antibiotics for the treatment of infection. Patients receiving prophylactic antibiotics are eligible.
* Patients with known untreated hepatitis B or C (HBV/HCV) or known human immunodeficiency virus (HIV). Note: evaluation for these is not required.
* Patients with uncontrolled intercurrent illness within 3 months prior to start of study treatment that could substantially increase risk of incurring AEs in the opinion of the treating investigator, including but not limited to:

* Symptomatic congestive heart failure \[CHF\],
* Uncontrolled cardiac arrhythmia, or
* Current psychiatric illness/social situations or other conditions that would limit compliance with study requirements or.

Note: Superficial bladder cancer, nonmelanoma skin cancers, and low-grade prostate cancer not requiring cytotoxic therapy should not exclude participation in this trial. Patients with CLL may be enrolled if they do not require active chemotherapy and their hematologic, renal and hepatic function meets criteria previously mentioned.
* Any other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding that contraindicates the use of an investigational drug, may affect the interpretation of the results, or may render the patient at high risk from treatment complications in the opinion of the treating investigator.
