Clinical and Molecular-Metabolic Phase II Trial of Perifosine for Recurrent/Progressive Malignant Gliomas

"Dosing will be continuous, and for the purpose of this trial a cycle will be defined as 28 days. Perifosine will be given as a 600 mg loading dose on day 1. The loading dose will be divided into 4 equal doses of 150 mg each. The first 3 doses should be given with food in the adult day hospital to allow intravenous antiemetic prophylaxis, and 4th dose at bedtime at home. The interval between doses of perifosine should be no less than 4 hours. On day 2, patients will start the maintenance dose of 100 mg daily at bedtime at home.~In addition to baseline serum, all patients will have weekly serum drawn during weeks 2-4."
