Tamoxifen and Bortezomib to Treat Recurrent Brain Tumors
NCT00108069 · View on ClinicalTrials.gov ↗
Study Summary
This study will determine whether the drugs tamoxifen and bortezomib can delay tumor growth in patients with recurrent glioma (malignant brain tumor). Tamoxifen may work by interfering with the internal signaling needed for the cancer to grow. Bortezomib may also interfere with tumor growth processes. Laboratory studies show that low doses of bortezomib significantly enhance glioma cell death when used with tamoxifen. Patients 18 years of age and older with glioma whose tumor does not respond to standard medical treatment and who are not taking enzyme-inducing anti-seizure medications such as Dilantin, phenobarbitol, or Tegretol, may be eligible for this study. Candidates are screened with a physical examination, blood tests, and magnetic resonance imaging (MRI) or computed tomography (CT). MRI and CT scans produce images of the brain that can show if the brain tumor is growing (see below). Participants receive treatment in 6-week cycles for up to 1 year. (The treatment duration may be extended in some patients who continue to tolerate the drug and show no signs of tumor growth after 1 year.) During each cycle, patients take six tamoxifen tablets twice a day every day and receive bortezomib by infusion into a vein on days 3, 6, 10, 13, 24, 27, 31 and 34. Treatment may continue as long as the tumor does not grow and the patient does not develop unacceptable side effects. In addition to drug treatment, patients undergo the following tests and procedures: * Periodic routine blood tests. * MRI or CT scan of the head before starting each new cycle. MRI uses a magnetic field and radio waves to produce images of body tissues and organs. CT uses x-rays to provide 3-dimensional views of the part of the body being studied. For both procedures, the patient lies on a table that slides into the cylindrical scanner. * Blood test to measure levels of bortezomib. Blood is drawn before the bortezomib infusion on days 3 and 24, and 4 hours after the infusion on day 24 of the first

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00108069
The ClinicalTrials.gov registry entry for NCT00108069 describes a study currently listed as completed. It is categorized as Phase 2, 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 43 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 1 condition, with Glioma appearing as the primary indexed condition, and to 2 interventions — of which Bortezomib 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: NCT00108069 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. 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.
