Phase II Study of Penicillamine, Low Copper Diet, amd Radiotherapy in Adults with Newly Diagnosed Glioblastoma
Alternate Title Penicillamine, Low Copper Diet, and Radiation Therapy in Treating Patients With Glioblastoma
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. Entry Criteria Disease Characteristics: Histologically proven supratentorial grade IV astrocytoma (glioblastoma multiforme) Prior/Concurrent Therapy: Biologic therapy: No prior immunotherapy for brain tumor No prior biologic therapy for brain tumor, including: Immunotoxins Immunoconjugates Antisense Peptide receptor antagonists Interferons Interleukins Tumor infiltrating lymphocytes Lymphokine activated killer cells Gene therapy No concurrent growth factors (e.g., filgrastim or epoetin alfa) Chemotherapy: No prior chemotherapy for brain tumor Endocrine therapy: Must be on stable corticosteroid regimen for at least 1 week (at least 5 days) No other prior hormonal therapy for brain tumor Radiotherapy: No prior radiotherapy for brain tumor Surgery: Recovered from prior surgery Other: No concurrent investigational agents No concurrent gold compounds (auronofin, gold sodium thiomalate) No concurrent herbal dietary supplements Patient Characteristics: Age: 18 and over Performance status: Karnofsky 60-100% Life expectancy: At least 2 months Hematopoietic: WBC at least 3000/mm3 Absolute neutrophil count at least 1500/mm3 Platelet count at least 100,000/mm3 Hemoglobin at least 10.0 g/dL No serious blood dyscrasias Hepatic: Bilirubin no greater than 2.0 mg/dL AST and ALT no greater than 4 times upper limit of normal (ULN) Albumin at least 3.0 g/dL PT and PTT no greater than 1.5 times ULN No liver failure Renal: Creatinine no greater than 1.7 mg/dL OR BUN no greater than 40 mg/dL No renal failure Other: Not pregnant or nursing Fertile patients must use effective contraception No serious infection No concurrent serious medical illness No allergy to penicillin or history of serious reaction to penicillamine No prior malignancy within the past 5 years except curatively treated carcinoma in situ or basal cell skin cancer Expected Enrollment 40A total of 40 patients will be accrued for this study. 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.Published Results Brem S, Grossman SA, Carson KA, et al.: Phase 2 trial of copper depletion and penicillamine as antiangiogenesis therapy of glioblastoma.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol. Back to Top |
