Temozolomide and O6-benzylguanine in Treating Patients With Newly Diagnosed, Recurrent, or Progressive Anaplastic Glioma
A Phase 1 study testing O6-benzylguanine, temozolomide and conventional surgery in people with Brain and Central Nervous System Tumors, run by Duke University at 1 site in United States.
Trial summary
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of combining temozolomide and O6-benzylguanine in treating patients who have newly diagnosed… Read more about this study

About this study
Official title: Phase I Trial of Temodar Plus O6-Benzylguanine (O6-BG) (NSC 637037) in the Treatment of Patients With Newly Diagnosed (Part 1) or Recurrent/Progressive (Parts 1 and 2) Cerebral Anaplastic Gliomas
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells.
PURPOSE: Phase I trial to study the effectiveness of combining temozolomide and O6-benzylguanine in treating patients who have newly diagnosed, recurrent, or progressive anaplastic glioma.
Read the detailed description
OBJECTIVES:
- Determine the dose of O6-benzylguanine (O6-BG) effective in producing complete suppression of tumor O6-alkylguanine-DNA alkyltransferase activity in patients with newly diagnosed (closed to accrual 12/19/2000) or recurrent or progressive cerebral anaplastic glioma.
- Determine the maximum tolerated dose of temozolomide administered after O6-BG in these patients.
- Determine the toxicity of this regimen in these patients.
- Determine the anti-tumor response in patients treated with this regimen.
OUTLINE: This is a dose-escalation, multicenter study.
- Part I: Patients receive escalating doses of O6-benzylguanine (O6-BG) IV continuously for 49 hours until the dose that produces the target depletion of tumor O6-alkylguanine-DNA alkyltransferase (AGT) is determined. Patients undergo a craniotomy after completion of the O6-BG infusion. (closed to accrual 12/19/2000)
- Part II: After determination of the O6-BG dose in Part I, patients with recurrent malignant gliomas receive O6-BG IV continuously for 49 hours beginning on day 1. Patients also receive oral temozolomide on day 1. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of temozolomide until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which no more than 1 of 6 patients experiences dose-limiting toxicity.
PROJECTED ACCRUAL: Approximately 20-30 patients (with 14 patients participating in Part II) will be accrued for this study.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing O6-benzylguanine, temozolomide and conventional surgery in people with Brain and Central Nervous System Tumors, run by Duke University at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 20 Jun 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00006474, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jun 2013.
