ZD6474 to Treat Advanced Brain Cancer in Patients

Malignant Gliomas Clinical Trial

Official title: A Phase I/II Trial of ZD6474 for Patients With Recurrent High-Grade and Progressive Low-Grade Gliomas

Status Completed

Clinical Trial Summary

Background:

In vivo experiments have documented the ability of ZD6474 to inhibit tumor growth in various preclinical tumor models. Given the pronounced neovasculature associated with malignant gliomas, and abundant published data demonstrating the dependence of glioma growth on the maintenance and proliferation of this neovasculature, ZD6474 represents a potentially promising new therapeutic approach to these otherwise refractory tumors.

Thus, we now propose a phase I trial of ZD6474 in patients with recurrent and progressive low-grade gliomas who are on P450-inducing anti-epileptic drugs and a phase II trial for patients with recurrent gliomas not taking P450-inducing anti-epileptic drugs.

Objective:

Phase I - To establish the maximally tolerated dose of ZD6474 and to obtain preliminary information regarding the spectrum of toxicities of ZD6474, and to obtain pharmacokinetic data to patients taking EIAED.

Phase I - To obtain preliminary information regarding potential anti-tumor activity of ZD6474 in patients taking EIAED.

Phase II - To establish data regarding the anti-tumor activity of ZD6474 and to collect information regarding the spectrum of toxicities in patients not taking EIAEDs.

Eligibility:

Patients with histologically proven malignant primary gliomas will be eligible for this protocol. Additionally, patients with progressive low-grade gliomas and patients with infiltrative brain stem gliomas, diagnosed radiographically rather than by biopsy will also be eligible.

Design:

Phase I - Group B patients will be accrued to the formal dose-escalation phase I trial. Groups of patients with recurrent high-grade gliomas will be accrued to increasingly higher doses of ZD6474 until the MTD is established.

Phase II - Patients will be treated at a dose of 300 mg day, every day, on a 4-week cycle.
