The purpose of this study is to:
? See if taking the study agent, armodafinil, at a dose of 150mg or 250mg, will improve problems with fatigue in patients who have been diagnosed with cancer and are experiencing fatigue.
? See the effects (good and bad) of taking Armodafinil compared to placebo (an inactive agent) on cancer related fatigue.
In this study, subjects will take either the study agent, armodafinil, or the placebo (inactive agent). They will not take both.
Armodafinil (Nuvigil®) is a medicine that is currently FDA approved to promote wakefulness in people who have sleep disorders. However, it is not been studied in people with cancer related fatigue.
