Mycophenolate Mofetil (CellCept) is an FDA approved, well tolerated, oral medication used to
prevent the body's immune system from attacking transplanted organs. It has never been
studied in patients with pancreatic cancer but some preliminary studies have shown that it
may antagonize tumor growth. The goals of this study are to find out how much of this drug
can safely be taken by patients with advanced pancreatic cancer and to assess the variation
of the level of the drug in the blood. Patients will take the drug twice a day at a given
dose and the safety of the drug will be monitored through patient symptoms and blood tests.
The disease burden will be assessed by radiographic studies at the beginning and end of the
study. The patient will take the drug for a total of eight weeks.
