This is an interventional treatment trial for Metastatic Pancreatic Cancer focused on measuring Adenocarcinoma, Hedgehog, Neoplasms, Digestive System Diseases, Neoplasms by Site, Digestive System Neoplasms, Neoplasms by Histologic Type, Pancreatic Neoplasms, Pancreatic Diseases, Carcinoma Read More

Inclusion Criteria:

1. Patient has histologically or cytologically confirmed metastatic adenocarcinoma of the pancreas. Patients with islet cells tumors are excluded. Biopsy within 14 days of starting treatment.
2. Patient has measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as >20 mm with conventional techniques or as >10 mm with spiral CT scan.
3. Patient has NOT received previous radiotherapy, surgery or chemotherapy or investigational drug therapy for the treatment of metastatic disease. If the patient received radiotherapy, chemotherapy or investigational therapy in the adjuvant setting it should be completed 3 weeks prior to enrollment. If a patient received gemcitabine in the adjuvant setting, tumor recurrence must have occurred at least six months after completing the last dose of gemcitabine
4. Age >18 years.
5. Life expectancy of greater than 1 month.
6. ECOG performance status 0 or 1 (Karnofsky >70%).
7. Patients must have adequate organ and marrow function

Exclusion Criteria:

1. Patient had received chemotherapy or radiotherapy for metastatic disease
2. Patient is receiving other investigational agents.
3. Patient has known brain metastases, unless previously treated and well controlled for at least three months (defined as clinically stable, no edema, no steroids and stable in 2 scans at least 4 weeks apart)
4. History of allergic reactions attributed to compounds of similar chemical or biologic composition to GDC-0449 or other agents used in the study.
5. Patients taking medications with narrow therapeutic indices that are metabolized by cytochrome P450 (CYP450), including warfarin sodium (Coumadin®) are ineligible.
6. Uncontrolled illness including, but not limited to, ongoing or active infection requiring IV antibiotics, symptomatic congestive heart failure not controlled with medication, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
7. Pregnant women are excluded
8. Patient has undergone a major surgery, other than diagnostic surgery (i.e. surgery done to obtain a biopsy for diagnosis without removal of an organ) within four weeks prior to Day 1 of treatment on this study.
9. History of other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates use of an investigational drug or that might affect interpretation of the results of the study or render the patient at high risk from treatment complications
