This is an interventional treatment trial for Adenocarcinoma of the Pancreas
Eligibility Criteria
Inclusion Criteria: Histologic or cytologic documentation of adenocarcinoma of the pancreas; documentation of disease extent by CT scan is required; radiologically measurable disease is not required; patients with documented invasion of adjacent organs (e.g., duodenum, stomach) by CT scan are not eligible No prior chemotherapy for metastatic disease If the patient received adjuvant therapy, it must have been completed at least 4 weeks prior to enrollment on this study; the patient must have recovered from all treatment related toxicities and must have evidence of disease progression following adjuvant treatment Prior radiation therapy, with or without a radiosensitizing dose of fluoropyrimidines, is allowed provided the patient has disease outside of the radiation port; at least 4 weeks must have elapsed from completion of the radiation therapy and all signs of toxicity must have resolved No prior treatment with gemcitabine or bevacizumab in the adjuvant or metastatic setting No current or recent (within 1 month) use of a thrombolytic agent Patients may not have had prior therapy with other VEGF inhibitors No recent invasive surgical procedures; this includes: Major surgical procedure (e.g. exploratory laparotomy or laparoscopy), open biopsy, or significant traumatic injury within 28 days prior to registration Fine needle aspirations or venous access device within 7 days prior to registration Anticipation of need for major surgical procedures during the course of the study No clinically significant cardiovascular disease; this includes: Uncontrolled hypertension (blood pressure > 150/90 on medication) New York Heart Association grade II or greater congestive heart failure Serious cardiac arrhythmia requiring medication No recent (within 6 months) arterial thrombotic events, including transient ischemic attack (TIA), cerebrovascular accident (CVA), unstable angina, or myocardial infarction (MI); patients with clinically significant peripheral artery disease (i.e., claudication on less than one block) are also ineligible No evidence of CNS disease, including primary brain tumor, or any brain metastasis No serious or non-healing wound, ulcer or bone fracture No serious active infection (viral, fungal bacterial); no infection requiring parenteral antibiotics at time of registration Patients with known hypersensitivity of Chinese hamster ovary cell products or other recombinant human antibodies are not eligible Patients with a "currently active" second malignancy other than non-melanoma skin cancers are not to be registered; patients are not considered to have a "currently active" malignancy if they have completed therapy and considered by their physician to be at less than 30% risk of relapse Women must be non-pregnant and non-breast feeding ECOG Performance status of 0, 1 or 2 Granulocytes ≥ 1,500/μl Platelet count ≥ 100,000/μl Creatinine ≤ 1.5 mg/dL or creatinine clearance ≥ 60 mL/min Total bilirubin ≤ 1 x upper limit of normal SGOT(AST) ≤ 2.5 x upper limit of normal PT INR =< 1.5, unless patient is on full dose warfarin Urine protein; for ≥ 1+ proteinuria, 24 hour urine collection must demonstrate < 1 gm of protein/24 hours Required diagnostic procedures: CT of the abdomen Chest x-ray
