• - Patients must have =< 2 recurrences/relapses of their tumor.

• - Women of childbearing potential must have a negative pregnancy test prior to study entry; cediranib has been shown to terminate fetal development in the rat, as expected for a process dependent on vascular endothelial growth factor (VEGF) signaling; women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.

• - Patients may not be breast-feeding a child.

• - Patients must have no concurrent malignancy except curatively treated basal or squamous cell carcinoma of the skin or carcinoma in situ of the cervix, breast, or bladder; patients with prior malignancies must be disease-free for >= five years.

• - Patients must have a Mini-Mental State Exam score of >= 15.

• - Patients must not have received prior cilengitide or cediranib therapy for their glioblastoma.

• - ARM 1 OF THE DOSE EXPANSION COHORT ONLY, the last treatment regimen the patient received must have included anti-VEGF treatment; a period of at least 28 days must have elapsed since the last bevacizumab treatment or a period of at least 21 days since the last short-acting anti-VEGF treatment, before treatment with cediranib/cilengitide can begin ARM 2 OF THE DOSE EXPANSION COHORT ONLY: patients must not have had prior anti-VEGF therapy.

• - Patients must not be on enzyme-inducing anti-epileptic drugs (EIAED); patients may be on non-enzyme inducing anti-epileptic drugs (NEIAED) or not be taking any anti-epileptic drugs.

Exclusion Criteria:

• - Patients with serious concurrent infection or medical illness, which would jeopardize the ability of the patient to receive the treatment outlined in this protocol with reasonable safety.

• - Patients with > 2 prior tumor recurrences/relapses.

• - Patients receiving concurrent investigational agents; patients may not be receiving any other cancer related investigational agents.

• - Although the following medications are not contraindicated on this study, each should be used with extreme caution due to potential nephrotoxic effects: vancomycin, amphotericin, pentamidine.

• - Patients may not be on anti-coagulants (dalteparin, warfarin, etc) - Patients with a mean QTc > 500 msec (with Bazett's correction) in screening electrocardiogram or history of familial long QT syndrome or other significant electrocardiogram (ECG) abnormality noted within 14 days of treatment are ineligible.

• - Greater than +1 proteinuria on two consecutive dipsticks taken no less than 7 days apart; however, if the first urinalysis shows no protein, then a repeat urinalysis is NOT required.

• - Patients with a New York Heart Association classification of III or IV.

• - History of allergic reactions attributed to compounds of similar chemical or biologic composition to cediranib or cilengitide.

• - Uncontrolled intercurrent illness including, but not limited to, hypertension (blood pressure > 140/90 mm Hg), ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

• - Pregnant women are excluded from this study because cediranib is a VEGF inhibitor with known abortifacient effects; breastfeeding should be discontinued if the mother is treated with cediranib.

• - Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with cediranib.

• - Patients on enzyme-inducing AED (EIAED) are not eligible for treatment on this protocol; patients previously treated with EIAED may be enrolled if they have been off the EIAED for 14 days or more prior to the first dose of cediranib or cilengitide.

• - Patients whose MRI scan demonstrates intratumoral hemorrhage or peritumoral hemorrhage are not eligible for treatment if deemed significant by the treating physician.

• - Patients must not have a known coagulopathy that increases risk of bleeding or a history of clinically significant hemorrhages in the past.

• - Patients receiving concurrent VEGF inhibitors are prohibited from participating in this study.

- Patients with conditions requiring concurrent drugs or biologics with proarrhythmic potential

PRIMARY OBJECTIVES:

• I. To determine the safety profile of cediranib (cediranib maleate) in combination with cilengitide in patients with recurrent glioblastoma (Part A).

SECONDARY OBJECTIVES:

• I. To estimate overall survival.

• II. To estimate the proportion of radiographic responses in recurrent glioblastoma patients with measurable disease treated with cediranib and cilengitide.

• III. To estimate the proportion of patients alive and progression free at 6 months (APF6) in patients with recurrent glioblastoma treated at the safe dose as determined in Part A (Part B).

• IV. To explore potential imaging techniques and biomarkers to capture the disease process through treatment.

OUTLINE: This is a dose-escalation study of cediranib maleate. Patients are initially enrolled in the dose-finding portion of the study (part A). Once the safe dose of cediranib maleate is determined, additional patients are enrolled in the dose-expansion portion of the study (part B). Part A (dose finding): Patients receive cediranib maleate orally (PO) once daily on days 1-28 and cilengitide intravenously (IV) over 1 hour on days 1, 4, 8, 11, 15, 18, 22, and 25. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity. Part B (dose expansion): Patients are assigned to 1 of 2 groups according to prior anti-VEGF therapy (yes vs.#46;no). Patients in both groups receive cediranib maleate (administered at the safe dose determined in part A) and cilengitide as in part A. After completion of study therapy, patients are followed up every 2 months.
