Repeated Superselective Intraarterial Cerebral Infusion (SIACI) of Bevacizumab With Temozolomide and Radiation Compared to Temozolomide and Radiation Alone in Newly Diagnosed GBM
What this study is about
Primary brain cancer kills up to 10,000 Americans a year. These brain tumors are typically treated by surgery, radiation therapy and chemotherapy, either individually or in combination. Present therapies are inadequate, as evidenced by the low 5-year survival rate for brain cancer patients, with median survival at approximately 12 months.
View original scientific description
Primary brain cancer kills up to 10,000 Americans a year. These brain tumors are typically treated by surgery, radiation therapy and chemotherapy, either individually or in combination. Present therapies are inadequate, as evidenced by the low 5-year survival rate for brain cancer patients, with median survival at approximately 12 months. Glioma is the most common form of primary brain cancer, afflicting approximately 7,000 patients in the United States each year. These highly malignant cancers remain a significant unmet clinical need in oncology. The investigators have completed a Phase I clinical trial that has shown that Superselective Intraarterial Cerebral Infusion (SIACI) of Bevacizumab (BV) is safe up to a dose of 15mg/kg in patients with recurrent malignant glioma. Additionally, the investigators have shown in a recently completed Phase I/II clinical trial, that SIACI BV improves the median progression free survival (PFS) from 4-6 months to 11.5 months and overall survival (OS) from 12-15 months to 23 months in patients with newly diagnosed GBM. Therefore, this two-arm, randomized trial (2:1) is a follow up study to these trials and will ask simple questions: Will this repeated SIACI treatment regimen increase progression free survival (PFS-primary endpoint) and overall survival (OS-secondary endpoint) when compared with standard of care in patients with newly diagnosed GBM? Exploratory endpoints will include adverse events and safety analysis as well as quality of life (QOL) assessments. The investigators expect that this project will provide important information regarding the utility of repeated SIACI BV therapy for newly diagnosed GBM and may alter the way these drugs are delivered to our patients in the near future.
Interventions
DRUG
Repeated Superselective Intraarterial Cerebral infusion (SIACI) of Bevacizumab (Avastin) with Temozolomide and Radiation
Subjects who are assigned to the IA BV+TMZ/RT group (Treatment Group), in addition to your standard of care cancer treatment, you will have a dose of bevacizumab delivered directly to your brain through superselective intra-cranial intra-arterial catheterization of the arteries that supply blood to your brain tumor along with the start of the initial 42 day oral temozolomide treatment. IA BV will be repeated every three months for a total of 3 infusions.
DRUG
Temozolomide and Radiation Alone
Subjects who are assigned to the TMZ/RT alone group (Control Group) you will receive standard of care cancer treatment that involves a daily oral dose of temozolomide for 42 days with radiation to the tumor followed by 28 days of rest and then repeated maintenance treatment cycles of daily oral temozolomide 5 days on and 23 days off.
Primary outcome measures
Overall survival (OS)
Time frame: 62 months
The primary end point will be overall survival (OS). Overall survival is defined as the time from randomization until death due to any cause. Participants who are still alive at the time of analysis will be censored at their last known alive date.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
