Ph I Dose Escalation Trial of Vandetanib in Combo w Etoposide for Malignant Gliomas

Primary Objective: To determine maximum tolerated dose \& dose limiting toxicity of vandetanib when combined with standard dosing of etoposide among patients with recurrent malignant glioma who are on \& not on enzyme-inducing anti-epileptic drugs (EIAEDs) Secondary Objectives: To assess safety \& tolerability of vandetanib + etoposide in this population; To evaluate pharmacokinetics of vandetanib among malignant glioma patients on \& not on EIAEDs when combined with etoposide. Exploratory Objective: To evaluate for evidence of anti-tumor activity of study regimen among recurrent malignant glioma patients including radiographic response rate, 6-month progression free survival (PFS) rate \& median PFS.
