Temozolomide and O6-Benzylguanine in Treating Children With Recurrent Brain Tumors
NCT00052780 · View on ClinicalTrials.gov ↗
Study Summary
Phase I trial to study the safety of combining O6-benzylguanine with temozolomide in treating children who have recurrent or refractory brain tumors. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. O6-benzylguanine may increase the effectiveness of temozolomide by making tumor cells more sensitive to the drug.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00052780
The ClinicalTrials.gov registry entry for NCT00052780 describes a study currently listed as completed. It is categorized as Phase 1, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 72 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Cancer Institute (NCI), which has 2,390 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 10 conditions, with Childhood Central Nervous System Germ Cell Tumor appearing as the primary indexed condition, and to 5 interventions — of which laboratory biomarker analysis is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00052780 reports 1 study location spanning 1 distinct geographic area — top geographies include Tennessee. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
