TTFields and Chemotherapy in Metastatic Pancreatic Adenocarcinoma (mPDAC)

Summary

The purpose of this clinical trial is to assess the safety and tolerability of TTFields in combination with chemotherapy in adults with metastatic pancreatic adenocarcinoma based on treatment-emergent adverse events of chemotherapy (modFOLFIRINOX) or device (TTFields). The main questions it aims to answer are: * Is TTFields treatment safe for the patients in combination with modFOLFIRINOX? * Are participants compliant with the treatment? * Is Is TTFields treatment effective in combination with modFOLFIRINOX against metastatic pancreatic adenocarcinoma?

    2. ANC higher than or equal to 1.5 x 10\^9/L without granulocyte colony-stimulating factor support.
    3. Platelet count higher than or equal to 100 x 10\^9/L without transfusion.
    4. Hemoglobin higher than or equal to 9 g/dL. Patients may be transfused to meet this criterion.
    5. Albumin higher than or equal to 2.5 g/dL.
    6. Serum bilirubin lower than or equal to 1.5 times the upper limit of normal (ULN); patients with known Gilbert´s disease may have a bilirubin value lower than or equal to 3 x ULN.
    7. INR and aPTT lower than or equal to 1.5 x ULN.
    8. AST, ALT, lower than or equal to 5 x ULN.
    9. Serum creatinine lower than or equal to 1.5 x ULN or Creatinine Clearance higher than or equal to 30ml/min (calculated using Cockcroft-Gault formula).
13. For women of childbearing potential: Negative serum pregnancy test within 14 days prior to C1D1. Agreement to remain abstinent (refrain from heterosexual intercourse) or use of contraceptive methods that result in a failure rate of lower than or equal to 1 percentage per year during the treatment period (combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal o transdermal); progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable o implantable); intrauterine device (IUD) or intrauterine hormone-releasing system (IUS); bilateral tubal occlusion or vasectomized partner) and for at least 180 days after the last study treatment. A woman is considered to be of childbearing potential if she is post-menarcheal, has not reached a postmenopausal state (higher than or equal to 12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus).

Exclusion Criteria:

Patients who present any of the following criteria for exclusion cannot be included in the clinical trial:

1. Malignancies other than pancreatic cancer within 3 years prior to Cycle 1 Day 1 (C1D1) with the exceptions of those with a negligible risk of metastasis or death (e.g., expected 5-year overall survival higher than 90 percentage), treated with expected curative outcome (such as but not limited to: adequately treated in situ carcinoma of the cervix, basal squamous or melanomatous cell skin cancer, localized prostate cancer treated surgically with curative intent, ductal carcinoma in situ of the breast treated surgically with curative intent).
2. Previous treatment with chemotherapy for metastatic pancreatic ductal adenocarcinoma.
3. Untreated CNS metastases. Treatment of brain metastases, either by surgical or radiation techniques, must have been completed at least 4 weeks prior to study entry.
4. Known dihydropyrimidine dehydrogenase deficiency or thymidylate synthase gene polymorphism predisposing the patient for 5-fluorouracil (5-FU) toxicity.
5. Previous radiation therapy within 14 days prior to C1D1 and/or persistence of radiation-related adverse effects.
6. Implantable electronic medical devices in the torso, such as pacemakers.
7. Known severe hypersensitivities to medical adhesives or hydrogel, or history of severe allergic, anaphylactic, or other hypersensitivity reactions to any of the study treatments used.
8. Spinal cord compression not definitively treated with surgery and/or radiation.
9. Uncontrolled pleural effusion, pericardial effusion, or ascites requiring recurrent drainage procedures.
10. Pregnant and lactating women
11. Patients who have received brivudine, sorivudine or analogues 4 weeks prior to Fluoracile administration.
12. Serious co-morbidities, including but not limited to:

    1. History of significant cardiovascular disease unless the disease is well controlled. Significant cardiac disease includes second/third degree hart block; significant ischemic heart disease; poorly controlled hypertension; congestive heart failure of the New York Heart Association (NYHA) Class II or worse.
    2. History of cerebrovascular accident (CVA) within 3 months prior to randomization or that is not stable.
    3. Active infection or serious underlying medical condition that would impair the ability of the patient to receive protocol therapy.
    4. History of any psychiatric condition that might impair patient´s ability to understand or comply with the requirements of the study or to provide consent.
