Clinical Trial Summary

This is a single arm phase II study. All patients will receive 3 cycles of the treatment of nab-paclitaxel (Days 1, 8 and 15), gemcitabine (Days 1, 8 and 15), and TTFields (worn every day for at least 18 hours). Following the initial 3 cycles of gemcitabine/nab-paclitaxel/TTFields treatment, patients will undergo restaging by CT or MRI. Patients with stable disease or better will undergo surgery for resection within 8 weeks following completion of initial chemotherapy although enrolling sites are encouraged to perform resection within 4 weeks of Cycle 3 D15 of therapy. If resection yields R0 or R1, patients will begin an additional 3 cycles of gemcitabine/nab-paclitaxel/TTFields treatment within 8 weeks of surgery. Based on available literature, it is expected that a percentage of patients will not undergo resection either due to disease progression or due to toxicities/ complications of the neoadjuvant segment of therapy. These patients will be included in the evaluable patients for both co-primary endpoints as well as the secondary endpoints including ORR, adverse events, and OS.

Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, the HCV viral load must be undetectable to be eligible for this trial.

Exclusion Criteria:

• Evidence of distant metastasis
• Patients with an electrical implantable device in the torso. Examples of electrical implanted medical devices include spinal cord stimulators, vagus nerve stimulators, pacemakers, and defibrillators.
• History of significant uncontrolled cardiovascular disease. Significant cardiac disease includes second/third degree heart block; significant ischemic heart disease; poorly controlled hypertension; congestive heart failure of the New York Heart Association (NYHA) Class II or worse (slight limitation of physical activity; comfortable at rest, but ordinary activity results in fatigue, palpitation or dyspnea).
• History of arrhythmia that is symptomatic or requires treatment. Patients with atrial fibrillation or flutter controlled by medication are not excluded from participation in the trial -Known allergy to medical adhesives or conductive hydrogel (gel used on electrocardiogram (ECG) stickers or transcutaneous electrical nerve stimulation (TENS) electrodes).
• Pregnant or breastfeeding (NOTE: breast milk cannot be stored for future use while the mother is being treated on study).
• Patients with a prior or concurrent malignancy whose natural history or treatment has the potential to interfere with the safety or efficacy assessment of the investigational regimen are not eligible for this trial.
• Patient has any other concurrent severe and/or uncontrolled medical condition that would, in the investigator's judgment, cause unacceptable safety risks, contraindicate patient participation in the clinical study or compromise compliance with the protocol: (e.g., chronic pancreatitis, chronic active hepatitis, active untreated or uncontrolled fungal, bacterial or viral infections, etc.)
• No prior malignancy is allowed except for adequately treated basal (or squamous cell) skin cancer, in situ cervical cancer or other cancer for which the patient has been disease and treatment-free for two years.
• Patient is unwilling or unable to comply with study procedures.

Outcome

Type	Measure	Description	Time frame	Safety issue

Primary	Rate of Resection	Determine the rate of resection following the neoadjuvant treatment with TTFields in combination with chemotherapy. Resectability rate will be calculated as the proportion of evaluable patients undergoing R0 or R1 resection following the neoadjuvant segment of therapy.	4 years
Secondary	Assess adverse events	Assess frequency and severity of adverse events when TTFields is added to gemcitabine and nab-paclitaxel chemotherapy using CTCAE v5 criteria. Adverse Events (AE): AEs and the maximum grade for each type of adverse events will be summarized for each patient separately for the following three periods: During perioperative therapy; Complications during surgery and post-operative period for 30 days; During adjuvant therapy	3 months, 5 months, and 10 months

Secondary	Overall Survival (OS)	Estimate the median OS is defined as the time from initiation of therapy to death from any cause. OS will be assessed from date of registration till death from any cause on an intention to treat basis.	4 years
Secondary	Rate of Major Histological Response	Assess the patterns and rate of major histological response.Pathologic response will be evaluated after the patient has had surgery, and will be based on local pathology review of the resected surgical specimen, according to the following (Treatment effect assessment will be per "College of American Pathology Protocol for the Examination of Specimens From Patients With Carcinoma of the Exocrine Pancreas"); Tumor Regression Grade: 0: Complete response - no residual tumor; 1: Moderate response - minimal residual cancer (single cells or small groups of cancer cells); 2: Minimal response - residual cancer outgrown by fibrosis; 3: Poor or no response - no definite response identified (minimal or no tumor kill; Extensive residual cancer)	4 years
Secondary	Patterns of Recurrence	Describe the patterns of recurrence. Pattern of recurrence will be assessed for patients undergoing resection and will be categorized into local vs distant. Loco-regional recurrence will be defined as any evidence of new disease within the pancreatic tumor bed based on surveillance scans. The pancreatic tumor bed includes: Superior mesenteric artery and vein lymph nodes; Lymph nodes in porta hepatis (bile duct, portal vein, hepatic artery lymph nodes); Lymph nodes around left renal vein, inferior vena cava or aorta; Celiac axis lymph nodes	4 years
