Study of Paclitaxel Protein Bound + Gemcitabine + Cisplatin + Hydroxychloroquine as Treatment in Untreated Pancreas Cancer

Inclusion Criteria:

* Patient has histologically or cytologically confirmed resectable, borderline resectable, or locally advanced (unresectable) PDAC (based upon Tempero et al 2016)
* Age ≥ 18 years.
* If a female patient is of child-bearing potential, she must have a negative serum pregnancy test (≥β-hCG) documented within 72 hours of the first administration of study drug
* If sexually active, the patient and partner must agree to use contraception considered adequate and appropriate by the Investigator
* Patient must have received no prior chemotherapy or radiation therapy for PDAC
* Patients must have normal organ and marrow function
* Patient has acceptable coagulation status as indicated by an INR ≤ 1.5 x ULN. Patients on anticoagulation can be included at the discretion of the investigator.
* Karnofsky Performance Status (KPS) of ≥70%.
* Have an elevated CA 19-9 (\>2X ULN) in the context of normal bilirubin

Exclusion Criteria:

* Patient will be excluded from this study if any of the following criteria apply: Evidence of metastatic disease. No metastatic disease defined as any one or more of the following; Suspicious lymphadenopathy outside of the standard surgical field (i.e. aortocaval nodes, distant abdominal nodes) or Radiographic evidence for metastatic disease in distant organs, peritoneum, or ascites
* Active, uncontrolled bacterial, viral, or fungal infection(s) requiring systemic therapy.
* Known infection with HIV, hepatitis B, or hepatitis C.
* Has undergone major surgery, other than diagnostic surgery (i.e.--surgery done to obtain a biopsy for diagnosis without removal of an organ), within 4 weeks prior to Day 1 of treatment in this study.
* History of allergy or hypersensitivity to the study drugs.
* Serious medical risk factors involving any of the major organ systems such that the Investigator considers it unsafe for the patient to receive an experimental research drug.
* Current, serious, clinically significant cardiac arrhythmias as determined by the investigator.
* Patient is unwilling or unable to comply with study procedures.
* Patient is enrolled in an industry sponsored clinical trial involving treatment with investigational therapy. Patients enrolled in HonorHealth sponsored research studies may be eligible to participate as long as their participation in the other research studies does not confound the data collected for this study.
* Patient with a history of interstitial lung disease, history of slowly progressive dyspnea and unproductive cough, sarcoidosis, silicosis, idiopathic pulmonary fibrosis, pulmonary hypersensitivity pneumonitis or multiple allergies.
* Use of non-FDA approved cannabinoids are prohibited. Total daily usage of up to 40 mg per day of marinol is acceptable.

Exclusion Criteria for Hydroxychloroquine Expansion Cohort only:

* Prolonged QTcF \> 450 ms for men and \> 470 ms for women at Screening. Electrolyte imbalances (e.g. hypokalemia/hypomagnesemia/hypocalcemia) must be corrected prior to first dose of hydroxychloroquine.
* Known second or third degree atrioventricular block.
* Patient is taking a concomitant medication that has "known" risk of QT prolongation or torsdades de pointe.
* Patient has pre-existing retinopathy.
* Patient has known hypersensitivity to hydroxychloroquine or other 4-aminoquinoline compounds.
