Details and patient eligibility

About

This study will examine an investigational (experimental) treatment using gemcitabine, cisplatin, and celecoxib. Preliminary studies have shown that this experimental treatment may be effective in reducing the size of cancerous tumors and/or preventing further tumor growth.

This is a phase II clinical trial studying the reactions of the patient's body and their tumor to the combination of gemcitabine, cisplatin, and celecoxib. The purpose of this study is to see if the tumor responds to this treatment and to determine how long the response lasts. This study will also look at what kind of side effects this experimental treatment causes and see how often these side effects occur. Blood levels of celecoxib will be measured to find out how this treatment affects factors (proteins) involved in new blood vessel formation and tumor growth (angiogenesis).

4. Patients must have performance status of 0-2 on the SWOG scale.
5. Patients must have an estimated life expectancy of at least 12 weeks.
6. Patients must have adequate bone marrow function: absolute neutrophil count >1,500/cmm, platelet count >100,000/cmm.
7. Patients must be informed of the investigational nature of this study and must give written informed consent prior to the receiving of treatment per this protocol.
8. Patients must practice effective birth control while receiving treatment.

Exclusion Criteria

1. Patients with endocrine tumors or lymphoma of the pancreas.
2. Patients with locally advanced pancreatic cancer.
3. Patients with a proven history (radiographic and/or endoscopic) of peptic ulcer or esophageal erosions within one year of enrollment onto the study.
4. Patients who have experienced asthma, urticaria, or allergic-type reactions after taking aspirin or other non-steroidal anti-inflammatory drugs.
5. History of active central nervous system (CNS) metastases.
6. Inadequate liver function (bilirubin >3.0 mg/dL); transaminases (AST/ALT) >3 times upper limit of institutional normal.
7. Inadequate renal function (creatinine >1.5 mg/dL).
8. Serious concomitant systemic disorders incompatible with the study (at the discretion of the investigator).
9. History of other malignancy, except for cancers that have been treated with a curative intent and patient is without evidence of active disease.
10. Unresolved bacterial infection requiring treatment with antibiotics.
11. Pregnant or lactating women may not participate in the study.
12. Patients who have allergy to any of the study drugs or sulfa drugs.
13. Patients infected with HIV-1 virus because of the undetermined effect of this chemotherapy regimen in patients with HIV-1 and the potential for serious interaction with anti-HIV medications.
