Phase II Trial of Bevacizumab, Radiation Therapy and Temodar Followed by Bevacizumab and Temodar With Continuation of Bevacizumab Beyond Progression (BBP-Bevacizumab Beyond Progression)


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.


Inclusion Criteria:



- Patients with histologically confirmed WHO Grade IV primary malignant glioma
(glioblastoma or gliosarcoma);

- Patients ≥ 18 years of age;

- An interval of at least 2 weeks, but not ≥ 8 weeks between prior surgical procedure
and initiation of treatment;

- Karnofsky Performance Status (KPS) ≥ 60%

- Platelet Count ≥ 125,000 cells/µL

- Absolute neutrophil count (ANC) ≥ 1,500 cells/µL

- Adequate renal function indicated by all of the following:

- Serum creatinine ≤ 1.25 x upper limit of normal (ULN) or calculated
creatinine clearance ≥ 50 ml/min

- Urine dipstick for proteinuria < 2+ unless a 24-hour urine protein < 1 g of
protein is demonstrated

- internationalized normalized ratio (INR) ≤ 1.5 and activated partial
thromboplastin time (aPTT) ≤ 1.5 x upper limit of normal (ULN) within 7 days
prior to first study treatment for patients not receiving anti-coagulation. The
use of full-dose oral or parenteral anticoagulants is permitted as long as the
INR or aPTT is within therapeutic limits (according to the medical standard of
the enrolling institution) and the patient has been on a stable dose of
anticoagulants for at least two weeks prior to the first study treatment.

- 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;

- Prior or current treatment with bevacizumab or other anti-angiogenic treatment (i.e.
anti-vascular endothelial growth factor (VEGF) or vascular endothelial growth factor
receptor (VEGFR) therapies or tyrosine kinase inhibitors) for any condition;

- 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;

- Evidence of > Grade 1 central nervous system (CNS) hemorrhage on post-operative MRI
scan.

- Inadequately controlled hypertension (defined as systolic blood pressure > 150 mmHg
and/or diastolic blood pressure > 100 mmHg) within 28 days of first study treatment;
