 Perifosine inhibits the AKT pathway a way cells communicate with each other. This pathway is felt to be important in the development of several types of cancers including chronic lymphocytic leukemia CLL or small lymphocytic lymphoma SLL. It is thought perifosine may be able to block this pathway and lead to an improvement in the CLL or SLL. The purpose of this trial is to see if perifosine is an effective treatment for relapsed or refractory CLL or SLL. Another purpose of this study is to look at the effect perifosine has on cells.
