Summary

Phase I: The purpose of this research study is to determine the safety of the combination treatment of ZD6474 (Vandetanib) with the standard therapy for glioblastomas and gliosarcomas, temozolomide (Temodar) and radiation therapy. This agent is investigational for the treatment of glioblastomas. We will determine the highest dose of ZD6474 (Vandetanib) that can be given safely when combined with temozolomide (Temodar) and radiation therapy. Phase II: The purpose of this research study is to determine the efficacy of the combination treatment of ZD6474 (Vandetanib) with the standard therapy for glioblastomas and gliosarcomas, temozolomide (Temodar) and radiation therapy. This agent is investigational for the treatment of glioblastomas. All subjects participating in this research study must NOT be taking a certain type of anti-seizure medication called enzyme inducing anticonvulsant drugs. These drugs include (but are not limited to) the following medications: Dilantin, Tegretol, Phenobarbital and trileptal.

PHASE I: To Define the Safety of ZD6474 (Vandetanib) With Radiation Therapy and Concomitant and Adjuvant Temozolomide in This Population.

Detailed description: Currently the standard treatment for glioblastomas and gliosarcomas is temozolomide (Temodar) and radiation therapy. This study is being done because research has shown that glioblastomas have genetic changes that may cause an excess of certain cell growth factors and their receptors, which can cause uncontrolled tumor growth. The drug being used in this research study, ZD6474 (Vandetanib), is designed to block the receptors to two of these growth factors, the vascular endothelial growth factor (VEGF) and the epidermal growth factor (EGF). These growth factors are important in pathways that promote tumor growth and increasing blood supply to the tumor. Blocking these receptors may reduce the blood supply to the tumor and help slow down tumor growth. There is also laboratory evidence that blocking these receptors may increase the sensitivity of glioblastomas to radiation therapy. This research study is a Phase I/II clinical trial. Phase I clinical trials test the safety of an investigational drug. Phase I studies also try to define the appropriate dose of the investigational drug to use for further studies. We will determine the highest dose of ZD6474 (Vandetanib) that can be given safely when combined with temozolomide (Temodar) and radiation therapy. The purpose of Phase II of this research study is to determine the efficacy of the combination treatment of ZD6474 (Vandetanib) with the standard therapy for glioblastomas and gliosarcomas, temozolomide (Temodar) and radiation therapy. It will look to see how patients fare on treatment (if they progress and when, how they are doing after 12 months of treatment). In this research study, the safety of the combination treatment of ZD6474 (Vandetanib) with the standard therapy for glioblastomas and gliosarcomas, temozolomide (Temodar) and radiation therapy will be further evaluated. We will also be looking at samples to see if there are correlations between them and how well patients do on treatment. This agent is investigational for the treatment of glioblastomas. "Investigational" means that the drug is still being studied and that research doctors are trying to find out more about it. It also means that the FDA (U. S. Food and Drug Administration) has not approved ZD6474 (Vandetanib) for use for your type of cancer. All subjects participating in this research study must NOT be taking a certain type of anti-seizure medication called enzyme inducing anticonvulsant drugs. These drugs include the following medications: Dilantin, Tegretol, Phenobarbital and trileptal.

- No history of arrhythmia (multifocal premature ventricular contractions (PVCs),

bigeminy, trigeminy, ventricular tachycardia, or uncontrolled atrial fibrillation) which is symptomatic or requires treatment (CTCAE grade 3) or asymptomatic sustained ventricular tachycardia. Atrial fibrillation, controlled on medication is not excluded.

- Subjects must not be taking concomitant medications known to prolong the QT interval

and have a risk of inducing Torsade de Pointes (TdP). Any concurrent medication with a known risk of inducing TdP that, in the investigator's opinion cannot be discontinued, will be allowed; however, these patients must be monitored closely.

- Subjects must not have active diarrhea that may affect the ability of the patient to

absorb or tolerate ZD6474 (Vandetanib).

- Subjects with confirmed diagnosis of human immunodeficiency virus (HIV) infection are

excluded at the investigator's discretion if he/she feels that 1) a potential drug interaction between ZD6474 (Vandetanib) and any of the patient's anti-HIV medications could influence the efficacy of the anti-HIV medication, or 2) it may place the patient at risk due to the pharmacologic activity of ZD6474 (Vandetanib).

- Subjects' pre-operative MRI must not demonstrate significant intratumoral or

peritumoral hemorrhage & post-operative MRI must not demonstrate a large amount of peri-operative parenchymal hemorrhage. (Patients may have postoperative intracavitary blood.)

heparin).

- Subjects must not have enrolled on this trial previously.

- Subjects must have had no involvement in the planning or conduct of the study

(applies to both AstraZeneca staff or staff at the study site).

- Any of the following lab results will result in patient exclusion from trial:

- Potassium: < 4. 0 mmol/L despite supplementation, or above the CTCAE grade 1

upper limit.

- Magnesium below the normal range despite supplementation, or above the CTCAE

grade 1 upper limit.

- Serum calcium above the CTCAE grade 1 upper limit.

NOTE: In cases where the serum calcium is below the normal range, 2 options would be available:

- The calcium adjusted for albumin is to be obtained and substituted for the measured

serum value. Exclusion is to then be based on the adjusted for albumin values falling below the normal limit.

- Determine the ionized calcium levels. If these ionized calcium levels are out of

normal range despite supplementation, then the patient must be excluded.
