The secondary objectives are:

• To evaluate the local tumor response in patients treated with the above regimen.

• To characterize the safety of the above regimen.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: M.D. Anderson Cancer Center

• Treatments: Capecitabine; Cetuximab; Gemcitabine; Oxaliplatin

Criteria

Inclusion Criteria:

1. Cytologic or histologic proof of adenocarcinoma of the pancreas is required prior to treatment. Patients can have tumor originating in any part of the pancreas. Islet cell tumors are not eligible. Only patients with non- metastatic, unresectable disease (AJCC 2002 stage T4 NX M0) are eligible. Computed Tomography (CT) findings of lung, liver, peritoneal metastasis are equivocal, are eligible. Patients who cannot undergo resection because of underlying medical problems are also eligible. Diagnosis of Pancreatic Adenocarcinoma by bile duce brushings are acceptable. Patients with regional nodal disease are eligible.

2. All patients must be staged with a physical exam, chest X-ray (CXR), and contrast-enhanced helical thin-cut abdominal CT. Unresectability is defined by CT criteria: a) evidence of tumor extension to the celiac axis or superior mesenteric (SM) artery, or b) evidence on either CT or angiogram of occlusion of the SM vein or SM/ portal vein confluence. If a tumor does not meet this definition and is found to be unresectable at surgical exploration, then that tumor is considered unresectable.

3. Patients must be 18 years and older. There will be no upper age restriction

4. Karnofsky performance status greater than or equal to 70 are eligible.

5. Patients must either be not of child bearing potential or have a negative urine pregnancy test within 72 hours of treatment. Patients are considered not of child bearing potential if they are surgically sterile (they have undergone a hysterectomy, bilateral tubal ligation or bilateral oophorectomy) or they have been postmenopausal for at least 12 months.

6. Women of childbearing potential must agree to practice adequate contraception and to refrain from breast-feeding, as specified in the informed consent. Sexually active males must practice contraception during the study.

7. Bone marrow function: absolute neutrophil count (ANC) >1,500/ul. Platelets >100,000/ul.

8. Renal function: creatinine clearance >30 mL/min (calculated with Cockcroft-Gault equation).

9. Hepatic function: Total bilirubin less than 5mg/dL. If the patient required an endobiliary stent, the bilirubin level must have declined on consecutive measurements indicating adequate biliary decompression; alanine aminotransferase (ALT) less than or equal to 5 times the upper limit of normal.

10. Neurologic function: neuropathy (sensory) < Common Toxicity Criteria (CTC) Grade 2.

11. Patients must sign a study-specific consent form, which is attached to this protocol.

Exclusion Criteria:

1. Patients with a history of prior metastatic cancer.

2. Patients must not have significant infection,i.e., requiring intravenous (IV) antibiotics, or other coexistent medical condition that would preclude protocol therapy.

3. Significant history of uncontrolled cardiac disease; i.e., uncontrolled hypertension, unstable angina, recent myocardial infarction (within prior 6 months), uncontrolled congestive heart failure, and cardiomyopathy with ejection fraction less than <30%.

4. Prior therapy which specifically and directly targets the estimated EGFR pathway.

5. Prior severe infusion reaction (bronchospasm, stridor, urticaria and/or hypotension) to a monoclonal antibody.

6. Any prior history of radiotherapy to the abdomen.

7. History or evidence upon physical examination of central nervous system (CNS) disease (e.g., primary brain tumor, seizures not controlled with standard medical therapy, any brain metastases, or history of stroke)

8. Prior unanticipated severe reaction to fluoropyrimidine therapy or known hypersensitivity to 5-fluorouracil.

9. Patients who have had an organ allograft.

10. Patients on Coumadin must be changed to Lovenox at least 1 week prior to starting capecitabine. Low dose (1 mg) Coumadin is allowed.

11. Patients taking Sorivudine or Brivudine A must be off of these drugs for 4 weeks prior to starting capecitabine. Patients taking cimetidine must have this drug discontinued. Ranitidine or a drug from another anti-ulcer class can be substituted for cimetidine if necessary.
