| Eligibility |
Inclusion Criteria:
- Histologically proven diagnosis of glioblastoma or other grade IV malignant glioma
(including variants of glioblastoma i.e., gliosarcoma, giant cell glioblastoma, etc.).
- Confirmation of tumor recurrence or progression on contrast magnetic resonance imaging
(MRI) (with and without gadolinium contrast) as determined by Response assessment in
neuro-oncology (RANO) criteria within 14 days prior to registration for patients who
did not have recent resection of their glioblastoma or only had a stereotactic biopsy.
- Patients having undergone recent resection (within 5 weeks prior to registration) of
their glioblastoma to treat current recurrence prior to study treatment must have
recovered from the effects of surgery (including patient's skin having fully recovered
from the surgical wound) Note: a 4-week window is required after surgery prior to
starting treatment. For central nervous system (CNS) -related stereotactic biopsies, a
minimum of 7 days must have elapsed prior to registration.
- Residual disease of recurrent glioblastoma is not mandated for eligibility into the
study. To best assess the extent of residual disease post-operatively, a
post-operative MRI scan must be performed prior to registration and is recommended to
be within 96 hours post-surgery (although 24-48 hours would be optimum). Note:
Patients who did have surgery with a post-operative contrast-enhanced scan falling
outside the 5-week window prior to registration, must have a repeat MRI scan within 14
days prior to registration.
- Patients with up to two recurrences are allowed.
- Failure on bevacizumab (either as a monotherapy or a combination) as most recent
regimen confirmed by tumor recurrence on MRI.
- The patient must have failed no more than one regimen of bevacizumab.
- The patient must not have received bevacizumab as an upfront treatment in newly
diagnosed glioblastoma.
- There must be a minimum of 14 days (i.e., an interval equal to or greater than 14
days) since last treatment with bevacizumab and registration
- History/physical examination within 14 days prior to registration
- Karnofsky performance status = 70 within 14 days prior to registration
- Age = 22
- Absolute neutrophil count (ANC) = 1,000 cells/mm3
- Platelets = 75,000 cells/mm3
- Hemoglobin (Hgb) = 9.0 g/dl (Note: The use of transfusion or other intervention to
achieve Hgb = 9.0 g/dl is acceptable.)
- Creatinine = 1.5 mg/dl
- Urine protein: creatinine (UPC) ratio < 1.0 within 14 days prior to registration OR
urine dipstick for proteinuria = 2+ (patients discovered to have > 2+ proteinuria on
dipstick urinalysis at baseline must have a UPC ratio done that is <1.0 to be
eligible. If the UPC ratio is = 1.0 then the patients should undergo a 24-hour urine
collection and must demonstrate = 1g of protein in 24 hours to be eligible).
*Note: UPC ratio of spot urine is an estimation of the 24-hour urine protein
excretion; a UPC ratio of 1 is roughly equivalent to a 24-hour urine protein of 1 gm.
UPC ratio is calculated using one of the following formulas:
- [urine protein]/[urine creatinine]: if both protein and creatinine are reported
in mg/dL
- [(urine protein) x0.088]/[urine creatinine]: if urine creatinine is reported in
mmol/L
- Serum total bilirubin = 1.5 x upper limit of normal (ULN) within 14 days prior to
registration
- Alanine transaminase (ALT) and aspartate transaminase (AST) = 3.0 x ULN within 14 days
prior to registration
- Patients on full dose anticoagulants (e.g., warfarin or low molecular weight (LMW)
heparin) must meet both of the following criteria:
1. No active bleeding or pathological condition that carries a high risk of bleeding
(e.g., tumor involving major vessels or known varices) within 14 days prior to
registration
2. One of the below criteria must be met based on patient's therapy:
1. Warfarin: In-range international normalized ratio (INR) (usually between 2
and 3) within 14 days prior to registration
2. LMW heparin or novel oral anti-coagulant: stable dose within 14 days prior
to registration
- Patients must have recovered from the toxic effects of prior therapy at the time of
registration as follows:
- 28 days from the administration of any investigational agent
- 28 days from administration of prior cytotoxic therapy with the following
exceptions:
- 14 days from administration of vincristine or irinotecan
- 42 days from administration of nitrosoureas
- 21 days from administration of procarbazine
- 7 days from administration of non-cytotoxic agents [e.g., interferon, tamoxifen,
thalidomide, cis-retinoic acid, etc. (radiosensitizer does not count)]
- Female patients of child-bearing potential must have a negative serum
pregnancy test within 14 days prior to registration.
- Patient must be maintained on a stable or decreasing dose of corticosteroid
for at least 5 days before the baseline scan.
- Minimum interval since completion of radiation treatment at the time of
registration is 90 days.
- Patient must provide study specific informed consent prior to study entry.
Exclusion Criteria:
- Prior invasive malignancy (except non-melanomatous skin cancer) unless disease free
for a minimum of 3 years. (For example, carcinoma in situ of the breast, oral cavity,
or cervix are all permissible).
- Infra-tentorial tumor.
- > 1 cm diameter of blood seen on contrast MRI (with and without gadolinium contrast)
- Major surgery such as intra-thoracic, intra-abdominal or intra-pelvic (with the
exception of craniotomy), open biopsy or significant traumatic injury = 4 weeks prior
to registration, or patients who have had minor procedures, percutaneous biopsies or
placement of vascular access device = 1 week prior to registration, or who have not
recovered from side effects of such procedure or injury.

electronic devices in the brain.
- Unstable angina and/or congestive heart failure requiring hospitalization within the

months prior to registration
- Pulmonary embolism (PE) within the last 6 months prior to registration
- Uncontrolled hypertension (defined by a systolic blood pressure (SBP) = 160 mm Hg or
diastolic blood pressure (DBP) = 100 mm Hg while on anti-hypertensive medications)
within 14 days prior to registration.
- Acute bacterial or fungal infection requiring intravenous antibiotics at the time of
registration.
- Chronic lung disease or Chronic Obstructive Pulmonary Disease exacerbation or other
respiratory illness requiring hospitalization or precluding study therapy at the time
