Early Phase 1
Recruiting
Conditions
Exocrine Pancreatic Cancer
Interventions
Registration Number
NCT04930991
Lead Sponsor
University of Oklahoma
Brief Summary

The purpose of this study is to test the safety of high dose omeprazole and see what effects that it has on patients with exocrine pancreatic cancer.

Detailed Description

During this study patients will receive treatment of omeprazole at the dose depending on group enrollment

* Group A will receive omeprazole 80 mg, twice a day for 12-14 days unless unacceptable toxicity

* Group B, will receive omeprazole 20 mg, once a day for 12-14 days

Patients will receive treatment for 2\~3 weeks during the study, and 2 months of follow up.

Total accrual is anticipated to take 2 years.
