About this trial

This is an interventional treatment trial for Exocrine Pancreatic Cancer focused on measuring pancreatic cancer, omeprazole

Eligibility Criteria

18 Years - 99 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Newly diagnosed exocrine pancreatic cancer with pathology confirmed as adenocarcinoma
  • Patient is a candidate for surgical resection of pancreatic cancer
  • ≥ 18 years old at the time of informed consent
  • ECOG Performance Status 0-2
  • Patients with or without neoadjuvant chemotherapy will be eligible
  • Ability to provide written informed consent and HIPAA authorization
  • Women of childbearing potential definition must have a negative pregnancy test within 14 days of registration. All women (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) are considered to have childbearing potential unless they meet one of the following criteria:
  • Prior hysterectomy or bilateral oophorectomy;
  • Has not had menses at any time in the preceding 24 consecutive months
  • Adequate organ function for surgical therapy

Exclusion Criteria:

  • Patients with pancreatic malignant tumor histologically confirmed as neuroendocrine or any other type of malignancies
  • Positive pregnancy test, pregnant, or breastfeeding
  • Known hypersensitivity to any component of the formulation or substituted benzimidazoles
  • Any other clinically significant laboratory abnormality that would compromise patient safety or the outcome of the study
  • Any clinically significant and/or uncontrolled cardiac-related abnormality that would compromise patient safety or the outcome of the study
  • Medical condition that might affect the absorption of study medications in the opinion of the investigator.
