Summary:

      This study tests regorafenib as a single agent in the treatment of metastatic pancreatic
      cancer patients who have progressed after prior chemotherapy with gemcitabine. The prognosis
      for these patients is particularly grim, no other standard treatment options exist, and novel
      approaches are desperately needed.

        Inclusion Criteria:

          -  Adenocarcinoma of the exocrine pancreas with metastatic disease.

          -  The site of the primary tumor confirmed to have been within the pancreas.

          -  Progression on at least one prior line of chemotherapy for locally-advanced or
             metastatic pancreatic cancer.

          -  Progression while on treatment with a gemcitabine regimen for advanced pancreatic
             cancer, or within 12 months of treatment with gemcitabine as part of adjuvant therapy.

             embolism within 3 months.

          -  Previously untreated or concurrent cancer that is distinct in primary site or
             histology except cervical cancer in-situ, treated basal cell carcinoma, or superficial
             bladder tumor. Patients surviving a cancer that was curatively treated and without
             evidence of disease for more than 3 years are allowed.

          -  Patients with pheochromocytoma.

          -  Known history of HIV infection or current chronic or active hepatitis B or C,
             requiring antiviral medication.

          -  Ongoing infection greater than or equal to Grade 2 NCI-CTCAE v4.0.

          -  Symptomatic metastatic brain or meningeal tumors.

          -  Presence of a non-healing wound, non-healing ulcer, or bone fracture.

          -  Renal failure requiring dialysis.
