High Dose Omeprazole in Patients With Pancreatic Cancer
Study Details
Study Description
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.
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
| Early Phase 1 |
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 14 days unless unacceptable toxicity
-
Group B, will receive omeprazole 20 mg, once a day for 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.
