Résumé
Date de début de l'étude : 1 mars 1999
Date à laquelle le premier participant a commencé l'étude.OBJECTIVES: I. Determine the effect of penicillamine and copper reduction on survival and time to progression in adults with newly diagnosed glioblastoma. II. Determine the effect of penicillamine on the reduction of serum copper in these patients. III. Determine whether penicillamine reduces the tumor volume, vascularity, invasion, and edema in these patients. OUTLINE: Patients receive oral penicillamine on the following schedule: Week 1: once daily Week 2: two times daily Week 3: three times daily Week 4: four times daily Week 5 to end of study: increased dose four times daily. Patients also receive oral pyridoxine daily and maintain a low copper diet (no greater than 0.5 mg/day). This regimen is continued for up to 2 years in the absence of disease progression or unacceptable toxicity. Radiotherapy is administered over 6 weeks, beginning on day 1 of penicillamine therapy. Patients are followed every month (with MRI every 2 months) until death. PROJECTED ACCRUAL: A total of 40 patients will be accrued for this study.
