Clinical Trial Summary

Studies which have separately studied bevacizumab for recurrent gliomas and bevacizumab for newly-diagnosed glioma have shown good results and the regimens have been well-tolerated by patients. This study seeks to investigate the use of bevacizumab with the standard therapy (radiation therapy and temozolomide) in newly diagnosed patients, followed by bevacizumab and temozolomide with the continuation of bevacizumab following progression. Two critical questions remain- the role of bevacizumab maintenance and bevacizumab at the time of progression in a patient previously treated with bevacizumab at the time of initial diagnosis.

Description:

Given the possible synergism with irinotecan and bevacizumab for colorectal carcinomas, the combination has been studied in gliomas. In a study of 21 patients, the combination of irinotecan and bevacizumab produced a 43% response rate, with acceptable toxicity. The response rate is significantly higher than irinotecan alone and any other therapy for recurrent glioma. There were two serious adverse events, one intracranial hemorrhage and one bowel perforation. At the Duke Brain Tumor Center, the investigators have treated over 1000 glioblastoma patients with a bevacizumab-containing regimen, and there is marked clinical benefit and acceptable toxicity. Our initial study looking at the combination of bevacizumab and irinotecan for patients with recurrent glioblastoma published in 2007 found impressive response rates and survival and corroborated the earlier experience of Starks-Vance. The investigators completed a study for newly diagnosed glioblastoma that utilized bevacizumab, radiation therapy and temozolomide followed by 6 months of bevacizumab, irinotecan and temozolomide. In addition, the group at University of California at Los Angeles published a study with bevacizumab, radiation therapy and temozolomide followed by 12 months of bevacizumab and temozolomide for newly diagnosed glioblastoma. These two phase II studies reported acceptable toxicity and a suggestion of improved survival compared to historical controls, and led to two large phase III randomized, placebo controlled studies of the addition of bevacizumab for newly diagnosed glioblastoma patients. The current proposal builds on the encouraging results of the addition of bevacizumab to the standard therapy for newly diagnosed glioblastoma patients. Two critical questions remain- the role of bevacizumab maintenance and bevacizumab at the time of progression in a patient previously treated with bevacizumab at the time of initial diagnosis. In addition, a retrospective analysis of data collected at our center from patients with recurrent disease suggests that continuation of bevacizumab at the time of progression may improve overall survival in comparison with cessation of bevacizumab.

• Patients will sign an Institutional Review Board-approved informed consent form.
• Female patients must not be pregnant or breast-feeding. Female patients of childbearing potential (defined as < 2 years after last menstruation or not surgically sterile) must use a highly effective contraceptive method (allowed methods of birth control, [i.e. with a failure rate of < 1% per year] are implants, injectables, combined oral contraceptives, intra-uterine device [Intrauterine Device (IUD); only hormonal], sexual abstinence or vasectomized partner) during the trial and for a period of > 6 months following the last administration of trial drug(s). Female patients with an intact uterus (unless amenorrhea for the last 24 months) must have a negative serum pregnancy test within 7 days prior to first study treatment.
• Fertile male patients must agree to use a highly effective contraceptive method (allowed methods of birth control [i.e. with a failure rate of < 1% per year] include a female partner using implants, injectables, combined oral contraceptives, Intrauterine Device (IUDs) [only hormonal], sexual abstinence or prior vasectomy) during the trial and for a period of > 6 months following the last administration of trial drugs.

Exclusion Criteria:

• Any prior treatment for any grade glioma, including, but not limited to gliadel wafers, immunotherapy (including vaccine therapy), radiation therapy or chemotherapy, irrespective of grade of the tumor (NOTE: 5-aminolevulinic acid (ALA)-mediated photodynamic therapy administered prior to surgery to aid in optimal surgical resection is not considered a chemotherapy agent.);
• Co-medication that may interfere with study results; e.g. immuno-suppressive agents other than corticosteroids;
• Active infection requiring intravenous antibiotics;

• Treatment with any other investigational agent within 28 days or 2 investigational agent half-lives (whichever is longer) prior to first study treatment;
• Prior, unrelated malignancy requiring current active treatment with the exception of cervical carcinoma in situ and adequately treated basal cell or squamous cell carcinoma of the skin;
