Condition brain and central nervous system tumors
Treatments thiotepa, adjuvant therapy, radiation therapy
Phase phase 2
Sponsor Children's Cancer and Leukaemia Group
Start date June 1995
End date November 1997
Trial size 30 participants
Trial identifier NCT00313521, CCLG-9405, CCLG-CNS-1995-01, CDR0000454503, EU-20575


RATIONALE: Drugs used in chemotherapy, such as thiotepa, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving chemotherapy and radiation therapy after surgery may kill any tumor cells that remain after surgery.

PURPOSE: This phase II trial is studying how well thiotepa works together with radiation therapy in treating young patients with newly diagnosed malignant brain tumors.

Additional Information

Official title Continuous Infusion Thiotepa in High Grade Astrocytic Tumors of Childhood and Adolescence A UKCCSG Phase II Study Involving the Brain Tumour and New Agent Groups
Description OBJECTIVES: Primary - Determine tumor response to adjuvant thiotepa followed by radiotherapy in pediatric patients with newly diagnosed malignant astrocytic tumors. Secondary - Determine the acute and chronic toxicity of thiotepa in these patients. - Determine the variability in thiotepa metabolism by measuring plasma and cerebrospinal fluid pharmacokinetics of thiotepa and tepa in these patients. - Develop a phase II study framework model, to determine the chemosensitivity to new, single-agent regimens in the treatment of high-grade (malignant) astrocytic tumors, including anaplastic astrocytoma, glioblastoma, giant cell glioblastoma, and gliosarcoma. - Determine the incidence of distant neuraxial metastases in patients at the time of relapse. - Determine the 1-year disease-free survival rate in patients treated with this regimen. OUTLINE: This is a multicenter study. Patients are stratified by age (3-15 vs 16-20 years of age). - Chemotherapy: Patients receive thiotepa IV continuously over 168 hours on days 1-7. Treatment repeats every 28 days for up to 2 courses. Patients then proceed to radiotherapy after blood counts recover. - Radiotherapy: Patients undergo external-beam radiotherapy once daily, 5 days a week, for approximately 6 weeks. - Post-radiation chemotherapy: Patients with complete, partial, or objective response, or stable disease after 2 courses of thiotepa may receive thiotepa alone for up to 8 more courses at the discretion of the treating physician. After completion of study treatment, patients are followed periodically. PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study.
