This is an interventional treatment trial for Pancreatic Neoplasms Read More

Inclusion Criteria:

• Patient must have histologically or cytologically confirmed pancreatic adenocarcinoma which is borderline resectable or locally advanced; tumors considered borderline include the following: (a) no distant metastases; (b) venous involvement of the superior mesenteric vein/portal vein demonstrating tumor abutment with or without impingement and narrowing of the lumen, encasement of the superior mesenteric vein/portal vein but without encasement of the nearby arteries, or short segment venous occlusion resulting from either tumor thrombus or encasement but with suitable vessel proximal and distal to the area of vessel involvement, allowing for safe resection and reconstruction; (c) gastroduodenal artery encasement up to the hepatic artery with either short segment encasement or direct abutment of the hepatic artery, without extension to the celiac axis; (d) tumor abutment of the superior mesenteric artery not to exceed 180 degrees of the circumference of the vessel wall
• Patient must have radiographically measurable disease defined as lesions that can be accurately measured in at least one dimension (longest diameter to be recorded) as >= 10 mm with computed tomography (CT) scan or magnetic resonance imaging (MRI) or >= 10 mm with calipers by clinical exam
• Patient myst be >= 18 years of age.
• Patient must have life expectancy of > 6 months
• Patient must have an Eastern Cooperative Oncology Group (ECOG) performance status =< 1

• Patient must have normal bone marrow and organ function as defined below:

  • Absolute neutrophil count >= 1,500/mcl
  • Platelets >= 100,000/mcl
  • Hemoglobin >= 9.0 g/dL
  • Creatinine should be below the upper limit of normal OR creatinine clearance >= 60 mL/min/1.73 m^2 for patients with creatinine levels above institutional normal limits
• Patient not on anticoagulation must have International Normalized Ratio (INR) and activated partial thromboplastin time (PTT) < 1.5 x ULN
• Patients who have had a stent placed for biliary obstruction can be included in the study
• Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control, abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she must inform her treating physician immediately

Exclusion Criteria:

• Patient must not have evidence of neuroendocrine tumor, duodenal adenocarcinoma, or ampullary adenocarcinoma
• Patient must not have a history of other malignancy =< 3 years previous with the exception of basal cell or squamous cell carcinoma of the skin which were treated with local resection only or carcinoma in situ of the cervix
• Patient must not have received any chemotherapy or radiation for pancreatic cancer
• Patient must not be receiving any other investigational agents
• Patient must not have brain metastases; such patients must be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events
• Patient must not have a history of allergic reactions attributed to compounds of similar chemical or biologic composition to PF-04136309, 5FU (fluorouracil), oxaliplatin, or irinotecan
• Patient must not be on any CYP3A4 inhibitors or inducers as they may have interaction with PF-04136309 and/or irinotecan
• Patient must not have an uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, any clinically active malabsorption syndrome, inflammatory bowel disease, any condition that increases the risk of severe irinotecan gastrointestinal toxicity, or psychiatric illness/social situations that would limit compliance with study requirements
• Patient must not be pregnant and/or breastfeeding
• Patient must not be known to be human immunodeficiency virus (HIV)-positive on combination antiretroviral therapy
