Phase I Trial of Super-Selective Intraarterial Cerebral Infusion of Cetuximab (Erbitux) for Treatment of Relapsed/Refractory Glioblastoma Multiforme and Anaplastic Astrocytoma
The high-grade malignant brain tumors, glioblastoma multiforme (GBM) and anaplastic
astrocytoma (AA), comprise the majority of all primary brain tumors in adults. Initial
therapy consists of either surgical resection, external beam radiation or both. All patients
experience a recurrence after first-line therapy, so improvements in both first-line and
salvage therapy are critical to enhancing quality-of-life and prolonging survival. It is
unknown if currently used intravenous (IV) therapies even cross the blood brain barrier
(BBB). Superselective Intraarterial Cerebral Infusion (SIACI) is a technique that can
effectively increase the concentration of drug delivered to the brain while sparing the body
of systemic side effects. One currently used drug called, Cetuximab (Erbitux) has been shown
to be active in human brain tumors but its actual CNS penetration is unknown. This phase I
clinical research trial will test the hypothesis that Cetuximab can be safely used by direct
intracranial superselective intraarterial infusion up to a dose of 500mg/m2 to ultimately
enhance survival of patients with relapsed/refractory GBM/AA. By achieving the aims of this
study the investigators will determine the the toxicity profile and maximum tolerated dose
(MTD) of SIACI Cetuximab. The investigators expect that this study will provide important
information regarding the utility of SIACI Cetuximab therapy for malignant glioma, and may
alter the way these drugs are delivered to the investigators patients in the near future.

There is no current standard of care for recurring GBM after patients receive Bevacizumab
(Avastin) intravenously (IV) at 10mg/kg with CPT-11 (Irinotecan). At that point, these
patients are deemed treatment failures and are given another experimental treatment. Because
of the blood brain barrier (BBB) where IV drugs do not penetrate the blood vessel walls well
to get into the brain, no one knows for sure if these IV drugs actually get into the brain
after infusion. Previous studies have shown that if you want to increase your penetration of
drug to the brain, that intra-carotid artery (intraarterial) delivery is superior to
standard intravenous delivery. Previous techniques using intraarterial (intracarotid)
infusion still were non-selective as drug delivery still went to all blood vessels in the
brain, so patients still had significant adverse events, such as blindness. Newer techniques
in interventional neuroradiology have allowed for a more selective delivery of catheters
higher up into the arterial tree where agents such as chemotherapies, can be delivered
without the risk of adverse affects such as blindness. In fact, studies here at Cornell have
developed very new and exciting super selective intraarterial delivery treatments for
Retinoblastoma, eye tumors with little toxicity and a clinical trial of intraarterial
delivery of Avastin is currently underway for GBM. Therefore, this trial will ask one simple
question: Is it safe to deliver a dose of Cetuximab intraarterially using these super
selective delivery techniques instead of the standard intravenous route of administration?
This should not only increase the amount of drug that gets to the tumor but also spare the
patient any adverse effects from a less selective delivery. Prior to that single dose of
intraarterial Cetuximab, the patient will also receive a dose of mannitol that opens up the
blood brain barrier to improve delivery of the agent to the brain. After that single dose of
Mannitol and Cetuximab intraarterially, the patient will be evaluated for 4 weeks to assess
for toxicity. After this point, the patient is done with the "experimental" aspects of the
protocol. If no toxicity at this point, then the patient will go on and get their chosen
chemotherapy as determined by their treating oncologist. In summary, this is a Phase I trial
that is designed to test the safety of a single dose of intraarterial delivery of Mannitol
and Cetuximab , prior to starting the patients next round of chosen chemotherapy
To summarize:
Current Standard of Care Therapy : None
Experimental portion of this proposal:
Day 0: Intraarterial Mannitol to open the blood brain barrier followed by Intraarterial
Cetuximab single dose (starting at 100mg/m2 and up to 500mg/m2)
Therefore the experimental aspects of this treatment plan will include:
1. Subjects will first be treated with Mannitol prior to chemotherapy infusion (Mannitol
25%; 3-10 mL/s for 30seconds) in order to disrupt the blood brain barrier. This
technique has been used in several thousand patients in previous studies for the IA
delivery of chemotherapy for malignant glioma.
2. To add a single intraarterial delivery (SIACI) of the Cetuximab for patients with
recurring or relapsing high grade glioma. After a one cycle observation period to
assess for toxicity from the IA infusion, the subject will receive a regimen of
chemotherapy to be decided by their treating oncologist The dose escalation algorithm
is as follows: We will use a single intracranial superselective intraarterial infusion
of Cetuximab, starting at a dose of 100mg/m2 in the first three patients. Assuming no
dose limiting toxicity during the next 28 days after the infusion, the patient will
then begin their standard chemotherapy regimen which is to be determined by their
treating oncologist. The doses will be escalated from 100, to 200, 300, 400 and finally
500mg/m2 in this Phase I trial.
Both hematologic and non-hematologic toxicity from the IA infusion of Cetuximab will be
determined and scored according to the NCI Common Toxicity Criteria (version 3.0).
Monitoring will also include an MRI of the brain at 4 weeks post infusion.
Most patients with GBM are also monitored every two months with serial history, neurological
and physical examinations together with serial blood counts, prothrombin time (PT), partial
thromboplastin time (PTT) and chemistries. In addition, most patients with GBM have an MRI
performed every two cycles or approximately every two months to assess for tumor
progression. .
Since this is a Phase I trial, response is not a primary endpoint of the trial. However, we
will evaluate response to the one time IA Cetuximab therapy with a a MRI with the injection
of contrast about 4 weeks after infusion. Follow-up of all patients in the trial regardless
of the chemotherapy regimen they try after the IA Cetuximab therapy will continue until
disease progression or death. Survival will be measured from the time of the dose of IA
Cetuximab®. We expect patients in the trial to monitored for 12 months.
This treatment may be harmful to a fetus . female subjects of childbearing age, will be
asked to practice birth control methods while participating in this research study and for 3
months following her treatment. These methods include oral contraceptives, contraceptive
shots, and barrier methods, such as condom use, sponges, and diaphragms. Fertile males are
required to use these barrier methods.
The patient may be responsible for any additional costs associated with enrollment in the
trial. All costs of the IA delivery and the cost of the drug will be submitted to the
patient's insurance provider.

external beam radiation for two weeks prior to treatment under this research
protocol.
- Patients must have adequate hematologic reserve with WBC greater than or equal to
3000/mm3, absolute neutrophils greater than or equal to 1500/mm3 and platelets

performed on each premenopausal female of childbearing potential immediately prior to
entry into the research study.

are cognitively impaired (which is common in GBM) are eligible for the trial.
Informed consent must be obtained at the time of patient screening (prior to Day 0 of
the procedure) either by the patient or a legalized authorized representative (LAR)
of the patient ( health-care proxy).
Exclusion Criteria:

risk of procreation while participating in this research trial and will be advised
that they must use effective contraception during and for a period of three months
