Modafinil to Reduce Persistent Fatigue in Patients Following Treatment for Cancer

The purpose of this study is to determine the efficacy of modafinil with regard to reducing cancer-related fatigue in cancer patients following chemotherapy or radiation therapy. Secondarily, the effect of modafinil on cognitive dysfunction in the same population will be assessed. The researchers hypothesize that administering modafinil (PROVIGIL®) to patients experiencing fatigue following completion of cancer treatment will lead to reduction in patient fatigue and prevention of or improvement in patient cognitive dysfunction.
