Inclusion Criteria	Exclusion Criteria
* Patients ≥18 years of age with histologically or cytologically confirmed evaluable or measurable locally advanced unresectable PDAC, or previously confirmed disease in the absence of a documented complete pathologic response. * Performance status score of 0 or 1 on the ECOG PS scale (scores range from 0 to 5, with higher numbers reflecting greater disability) * Suitable venous anatomy on a standard portal venous phase imaging as defined by absence of portal, splenic, or superior mesenteric vein complete occlusion Note: As long as there is not complete occlusion and the Interventional Radiologist confirms that the target vein can be accessed, patients may be suitable for enrollment. All 3 veins do not have to be patent for eligibility. * Having received standard of care chemoradiation therapy or a systemic chemotherapy regimen without a complete radiographic response. Standard of care chemotherapy includes gemcitabine + nab-paclitaxel, or FOLFIRINOX; for others discuss with medical monitor. Radiation with or without concurrent chemotherapy is also acceptable as a standard of care regimen * Able to understand the study and provide written informed consent prior to any study procedures * Has not received prior cytotoxic chemotherapy or targeted therapy within 14 days, or external radiation therapy within 4 weeks prior to screening * Low-burden, asymptomatic metastatic disease permitted if: 1. Metastatic disease poses no imminent threat to the patient 2. Patient is otherwise asymptomatic with respect to metastases 3. Metastases are limited to liver, lung, and/or bone 4. No single lesion greater than 5 cm 5. Less than 5 metastatic lesions total 6. No brain or peritoneal metastases Pancreatic disease must be the dominant determinant of the patient's prognosis and clinical course * Has no prior history of or other concurrent malignancy unless the malignancy is clinically insignificant, no ongoing treatment is required, and the patient is clinically stable * Has a life expectancy of \>3 months at screening as estimated by the Investigator * Has a QTc interval ≤480 msec * All associated clinically significant (in the judgment of the Investigator) drug-related toxicity from previous cancer therapy must be resolved (to Grade ≤1 or the patient's pretreatment level) prior to study treatment administration (Grade 2 alopecia, grade 2 peripheral neuropathy from prior chemotherapy, and endocrinopathies controlled on replacement therapy are allowed). * Has adequate organ function at screening as evidence by: 1. Platelet count \>80,000/μL 2. Hemoglobin ≥8.0 g/dL 3. White blood cell (WBC) count \>2,000/μL 4.
