A Phase II study of Bevacizumab and Erlotinib after Radiation Therapy and Temozolomide in patients with newly diagnosed glioblastoma without MGMT promoter methylation
The goal of this clinical research study is to learn if the combination of bevacizumab and erlotinib after treatment with temozolomide and radiation therapy will help to control glioblastoma when a certain gene called MGMT is turned "on". The safety of this drug combination will also be studied.

Primary To determine the overall survival for patients with newly diagnosed glioblastoma (GBM) with unmethylated MGMT promoter treated with Bevacizumab and Erlotinib after radiation therapy (RT) + Temozolomide. Secondary To determine the 12 and 18 month progression free survival (PFS) for patients with newly diagnosed GBM with unmethylated MGMT promoter treated with Bevacizumab and Erlotinib after RT + Temozolomide. To assess radiographic response rates. To assess changes in tumor blood flow based on MR Perfusion (optional study). To collect tissue and plasma to evaluate for gene methylation studies (Northwestern and Northshore sites only), RT-PCR and correlate with tumor tissue, imaging and outcomes (optional). To collect safety data on the combination of Bevacizumab and Erlotinib for patients with newly diagnosed GBM with unmethylated MGMT promoter treated with Bevacizumab and Erlotinib after RT + Temozolomide.
IRB Review and Approval Date: 02/16/2010
Recruitment Status: Not Accepting
Projected Accrual: 115
1) Patients with histologically proven newly diagnosed GBM or
gliosarcoma will be eligible for consent but will require confirmation
of an unmethylated MGMT promoter to be eligible for treatment post RT.
If MGMT is indeterminate or methylated, the patient is not eligible.
Consent must be obtained prior to starting RT. Determination of MGMT
status is strongly recommended to have been determined prior to starting
RT to ensure that all treatment options available would still be
possible for the ineligible patient. A pathology report of most recent
surgery or biopsy must be available at registration.
2) Patients must have at least 1 block of tumor tissue of sufficient size (at least 1 cm3) for analysis of MGMT status; CUSA (Cavitron ultrasonic aspirator)-derived material is not allowed; fresh frozen tumor tissue acquisition is encouraged for tumor banking at local institution.
3) Diagnosis must be made by surgical excision, either partial or complete. Stereotactic biopsy will not be allowed because this will not provide sufficient tissue for the MGMT analysis.
4) The tumor must have a supratentorial component.
5) Post tumor resection, all patients must have a post operative MRI done no more than 96 hours after surgery or a study > 4 weeks (+/- 7 days) after surgery, but before initiation of radiation treatment in order for an accurate assessment to be done post RT. Another contrast enhanced MRI or CT scan must be performed on no steroids or a stable dose of steroids for 5 days or more, within 14 days before starting treatment with Bevacizumab and Erlotinib.
6) (5. continued) MR perfusion is optional but recommended. The same type of enhanced scan, i.e., MRI or CT must be used throughout the period of protocol treatment for tumor measurement. Patients who can only get a CT scan will not be able to undergo MR Perfusion: a) Evaluable or measurable disease following resection of recurrent tumor is not mandated for eligibility into the study. b) The tumor must have no MGMT promoter methylation to qualify for protocol treatment post RT.
7) No chemotherapy is allowed prior to starting RT + Temozolomide including Gliadel Wafers.
8) Patients who have started RT + Temozolomide will not be eligible for treatment after RT unless consent was signed before RT began.
9) (8. continued) Eligible patients will start Bevacizumab and Erlotinib 4 weeks (+/- 7 days) after the completion of RT + Temozolomide. a) RT plans will need to be verified prior to treatment to confirm that the treatment plan was conducted as the protocol outlined or similar based on the PI assessment, such as IMRT. b) The patient must have completed the full course of RT with standard dose temozolomide (75 mg/m2 x 42 days +/- 3 days) prior to initiating Bevacizumab and Erlotinib.
10) Patients must be > 18 years old.
11) Patients must have a Karnofsky performance status of >/= 70.
12) Patients must have adequate bone marrow function (WBC > 3,000/mcL, ANC > 1,500/mm3, platelet count of > 100,000/mm3, and hemoglobin > 10 mg/dl), adequate liver function (SGOT/SGPT and bilirubin < 3 times ULN), and adequate renal function (creatinine < 1.5 mg/dL) before starting therapy. These tests must be performed within 7 days prior to registration step 2.
13) This study was designed to include women and minorities, but was not designed to measure differences of intervention effects. Males and females will be recruited with no preference to gender. Minorities will actively be recruited to participate.No exclusion to this study will be based on race.
14) All patients must sign an informed consent indicating that they are aware of the investigational nature of this study. Patients must sign informed consent prior to registration and before undergoing any study-related procedures. Patients must sign an authorization for the release of their protected health information.
1) Patients must not have any significant medical illnesses that in the
investigator’s opinion cannot be adequately controlled with appropriate
therapy, would compromise the patient’s ability to tolerate this therapy
or any disease that will obscure toxicity or dangerously alter drug metabolism.
2) Patients must not have proteinuria at screening (within 7 days before registration step 2) as demonstrated by either a) Urine protein:creatinine (UPC) ratio >/= 1.0 at screening OR b) Urine dipstick for proteinuria >/= 2+ (patients discovered to have >/= 2+ proteinuria on dipstick urinalysis at baseline should undergo a 24 hour urine collection and must demonstrate </= 1g of protein in 24 hours to be eligible).
3) Patients must not have inadequately controlled hypertension (defined as systolic blood pressure >/=140 and/or diastolic blood pressure >/=90 mmHg)
4) Patients must not have any prior history of hypertensive crisis or hypertensive encephalopathy
5) Patients must not have New York Heart Association Grade II or greater congestive heart failure.
6) Patients must not have history of myocardial infarction or unstable angina within 6 months prior to study enrollment or no evidence of recent myocardial infarction or ischemia by the findings of S-T elevations of </= 2 mm using the analysis of an EKG performed within 14 days before registration step 2.
7) Patients must not have history of stroke or transient ischemic attack within 6 months prior to study enrollment step 2.
8) Patients must not have significant vascular disease (e.g., aortic aneurysm, history of aortic dissection) or clinically significant peripheral vascular disease
9) Patients must not have evidence of bleeding diathesis or coagulopathy. Prothrombin time/international normalized ratio (PT INR) < 1.4 for patients not on warfarin
10) Patients on full-dose anticoagulants (e.g., warfarin or LMW heparin) must meet both of the following criteria: a) No active bleeding or pathological condition that carries a high risk of bleeding (e.g., tumor involving major vessels or known varices) b) In-range INR (usually between 2 and 3) on a stable dose of oral anticoagulant or on a stable dose of low molecular weight heparin.
11) Patients must not have major surgical procedure, open biopsy, or significant traumatic injury within 28 days prior to study enrollment step 2 or the anticipation of need for major surgical procedure during the course of the study, exception is craniotomy.

13) Patients must not have a history of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within 6 months prior to study enrollment step 2.
14) Patients must not have serious, non-healing wound, ulcer, or bone fracture due to the effects on vasculature by Bevacizumab which may impair healing.
15) Patients may not be known to be HIV-positive. HIV testing is not required for study participation.
