   11. Urine Protein ≤ Grade 1
9. For patients on warfarin: Must have maintained a stable INR on a stable dose of warfarin for at least 4 weeks prior to start of treatment.

Primary Exclusion Criteria:

1. Patients who have received prior radiation for their current malignancy at the location of interest.
2. Patients who have not recovered (to Grade 1 or less) from adverse events, other than alopecia and neuropathy, caused by previously administered chemotherapeutic agents, at the discretion of the PI/treating physician.
3. Tolfenamic acid use concurrent with, or within 8 weeks prior to the diagnosis of pancreatic cancer.
4. Current use of any non-steroidal anti-inflammatory agents (NSAIDs), including aspirin, (other than tolfenamic acid) within 4 weeks prior to the start of active treatment.
5. Previous history of hypersensitivity reactions (e.g. asthma, rhinitis, angioedema or urticaria) in response to ibuprofen, aspirin or other NSAIDs.
6. History of recurrent peptic ulcer/hemorrhage (two or more distinct episodes).
7. History of gastrointestinal bleeding or perforation related to previous use of NSAIDS.
8. New York Heart Association Functional Classification of 3 or 4.
9. Known autoimmune disease that could preclude the use of radiation, at the discretion of the treating physician.
10. History or evidence of CNS disease (e.g., any brain metastases, primary brain tumor, seizures not controlled with standard medical therapy, or history of stroke).
11. Known HIV positive.
12. Active systemic infection requiring parenteral antibiotic therapy.
13. Receiving systemic steroid therapy. (Inhaled steroid therapy is allowable.)
14. History of other malignancies within the last 5 years with the exception of non- melanoma skin cancer or cervical cancer in situ that has been successfully treated.
