Study of Single Agent Perifosine for Recurrent Pediatric Solid Tumors

Open label, phase I study of oral perifosine in recurrent/progressive pediatric solid tumors. This will be a dose escalation study to determine the maximum tolerated dose (MTD) of perifosine alone in recurrent/progressive pediatric tumors. A standard 3+3 dose escalation design will be employed with 3-6 patients at each dose level. All patients will receive perifosine at a loading dose on the first day, followed by a maintenance dose to start on day two until progression each patient will be assigned to a dosing group based on one's body surface area (BSA).
