• Histologically or cytologically confirmed pancreatic adenocarcinoma or adeno-squamous carcinoma with liver metastasis.

∙ Subjects with additional sites of metastasis, except known brain metastasis, are eligible.

‣ Histologies excluded include squamous, small cell carcinoma, and acinar cell carcinoma. However, adeno-squamous histology can be enrolled.

‣ Patients who have recurrence or metastasis after surgery and adjuvant therapy do not need repeat biopsy for confirmation of recurrence if clinical suspicion is high per scans (MRI/CT scan), with and without CA 19-9 elevation, specifically if biopsy is unsafe or technically difficult.

• Patients with no prior lines of therapy for the treatment of stage IV metastatic disease.

∙ Patients could have had prior neoadjuvant or adjuvant chemotherapy or chemo-radiotherapy.

• i. Patients who received gemcitabine-based adjuvant chemotherapy can enroll if they progress greater than 6 months after completion of the therapy; ii. Patients who progress while on adjuvant FOLFIRINOX can enroll immediately.

• Male and female patients at least 18 years of age

• Laboratory data as specified below:

• Hematology:

• \- ANC greater than 1500 cells/mm3,

• \- platelet count greater than 100,000 cells/mm3, and

• \- Hemoglobin greater than 8 g/dL.

⁃ Hepatic

• Total bilirubin less than 1.5 X ULN;

∙ alanine aminotransferase (ALT) or aspartate aminotransferase (AST) less than 3 X ULN.

• For patients with known liver metastases or liver neoplasms: alanine aminotransferase (ALT) or aspartate aminotransferase (AST) less than 6.0 X ULN and total bilirubin less than 3 x ULN.

⁃ Renal:

• serum creatinine WNL or creatinine clearance greater than 50 mL/min.

• QT intervals: QTc less than or equal to 470 msec for men and less than or equal to 490 msec for women. (As measured by Hodges' Equation: QTc = QT + 1.75(rate-60) where QTc = corrected QT interval and rate = ventricular rate/min).

• Estimated life expectancy of at least 3 months

• ECOG Performance Status 0-1.

• Ability to operate the Novo TTF-100L (P) system.

• Patients must have measurable disease on scans per RECIST 1.1.

⁃ Negative serum pregnancy test within 14 days prior to the first dose of study therapy for women of child-bearing potential (WCBP), defined as a sexually mature woman who has not undergone a hysterectomy or who has not been naturally post-menopausal for at least 24 consecutive months (i.e., who has had menses any time in the preceding 24 consecutive months). Sexually active WCBP and male subjects must agree to use adequate methods to avoid pregnancy (oral, injectable, or implantable hormonal contraceptive; tubal ligation; intra-uterine device; barrier contraceptive with spermicide; or vasectomized partner) throughout the study and for 28 days after the completion of study treatment.
