Bevacizumab and Carmustine in Treating Patients With Relapsed or Progressive High-Grade Glioma

Study Overview
=================
Brief Summary
-----------------
RATIONALE: Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Drugs used in chemotherapy, such as carmustine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving bevacizumab together with carmustine may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving bevacizumab together with carmustine works in treating patients with relapsed or progressive high-grade glioma.

Detailed Description
-----------------
OBJECTIVES: Primary To determine the 6-month progression-free survival of patients with relapsed or progressive high-grade gliomas treated with bevacizumab and carmustine. Secondary To evaluate the radiographic response to this regimen as measured by MRI and PET scan with image fusion. To utilize novel brain imaging to differentiate between a radiographic response due to tumor shrinkage and a radiographic response due to decreased vasogenic edema. To evaluate the safety and toxicity of this regimen in these patients. To evaluate the overall survival of these patients. OUTLINE: Patients receive bevacizumab IV on days -7, 8, 22, 36, and 50 of course 1 and on days 8, 22, 36, and 50 of all subsequent courses. Patients also receive carmustine IV over 4 hours on day 1. Treatment repeats every 56 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. After completion of study therapy, patients are followed every 3 months.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Progression-free Survival | Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions. | Time from first day of treatment to the first observation of disease progression or death due to any cause (up to 7 years). | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Radiographic Response to Therapy | Response measured using MRI and PET with image fusion | One year | 
| Differentiate a Radiographic Response Due to Tumor Shrinkage From a Radiographic Response Due to Decreased Vasogenic Edema | Measurements made by novel brain imaging | One year | 
| Safety and Toxicity | Subjects will be assessed clinically for toxicity prior to, during, and after each infusion. NCI CTCAE 3.0 Common Terminology Criteria (CTC) for Adverse Events for toxicity and Adverse Event Reporting will be utilized. | One year | 
| Overall Survival |  | Time from first day of treatment to time of death due to any cause (up to 7 years). |
