A Biomarker and Phase II Study of GW572016 in Recurrent Malignant Glioma
Abstract
This study will examine whether an experimental drug called GW572016 can delay tumor growth in patients with glioblastoma multiforme (GMB, a malignant brain tumor). GW572016 is believed to affect cancer cell function by interfering with the internal signaling needed for the cancer to grow. The study will also determine whether the presence of specific proteins in the tumor can predict what effects GW572016 will have on the tumor.
Patients 18 years of age and older with GMB whose brain tumor does not respond to standard medical treatment and who can undergo surgery for their tumor may be eligible for this study. Candidates are screened with a physical examination and neurocognitive examination, blood tests, electrocardiogram (EKG), echocardiogram (ultrasound test of heart function) or MUGA scan (nuclear medicine test of heart function), magnetic resonance imaging (MRI) of the head, and computed tomography (CT) of the head. CT uses x-rays and MRI uses a magnetic field and radio waves to show brain structure.
Participants undergo the following tests and procedures:
* MRI and blood tests before surgery.
* Surgery to remove the brain tumor.
* Follow-up MRIs every 8 weeks after surgery.
* Follow-up echocardiograms or MUGA scans every 8 weeks after surgery.
* GW572016 treatment starting 7-10 days before surgery and continuing until the patient or doctor decides it is in the patient's best interest to stop it or until the tumor worsens. (The drug is stopped temporarily for surgery…
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 9 participants or records.
