Clinical and Molecular-Metabolic Phase II Trial of Perifosine for Recurrent/Progressive Malignant Gliomas
The purpose of this study is to test the effectiveness of perifosine in preventing further tumor growth using the established optimal dose of the drug. A second goal is to determine if perifosine can block the molecules in the tumor that drive it to divide and grow.

Following a diagnosis of tumor recurrence or progression, all patients will receive perifosine monotherapy until toxicity, progression, or death.
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.
Other Name: NSC 639966, D21266, KRX-0401
This is a phase II study of the small molecule inhibitor perifosine (NSC 639966, D21266, KRX-0401) in the treatment of patients with recurrent glioblastoma multiforme (GBM) and other recurrent malignant gliomas. The goal of the phase II study is to determine efficacy as measured by the progressionfree survival rate after 6 months of treatment. Secondary goals include determination of molecular and metabolic effects of perifosine by tissue analysis and PET imaging.
In addition, when cytoreductive surgery is recommended as part of the standard of care at study entry, patients will be considered for a "surgical arm." In this case, patients will receive perifosine for 5-10 days before surgery during which tumor will be aliquoted both for diagnostic purposes and for molecular effects of the drug in vivo and for analysis of drug penetration into tumor tissue.
