Combination Chemotherapy Followed by Peripheral Stem Cell Transplantation or Bone Marrow Transplantation in Treating Patients With Brain Cancer

Brain and Central Nervous System Tumors Clinical Trial

Official title: Dose Escalation of Temozolomide in Combination With Thiotepa and Carboplatin With Autologous Stem Cell Rescue in Patients With Malignant Brain Tumors With Minimal Residual Disease

Status Completed

Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Peripheral stem cell transplantation or bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells.

PURPOSE: Phase I trial to study the effectiveness of combining temozolomide, thiotepa, and carboplatin followed by peripheral stem cell transplantation or bone marrow transplantation in treating patients who have brain cancer.

Clinical Trial Description

OBJECTIVES:

• Determine the maximum tolerated dose of temozolomide in combination with thiotepa and carboplatin followed by autologous peripheral blood stem cell or bone marrow transplantation in patients with recurrent high-grade brain tumors with minimal residual disease or newly-diagnosed malignant glioma with minimal residual disease following irradiation.

OUTLINE: This is a dose-escalation study of temozolomide.

Patients receive filgrastim (G-CSF) subcutaneously (SC) once daily for 3 consecutive days. After the third dose of G-CSF, patients undergo leukapheresis to collect peripheral blood stem cells (PBSC). Patients who do not have adequate PBSC may undergo bone marrow harvest.

Patients then receive oral temozolomide every 12 hours on days -10 to -6 and thiotepa IV over 3 hours and carboplatin IV over 4 hours on days -5 to -3.

PBSC or bone marrow are reinfused on day 0. Beginning on day 1, patients receive G-CSF SC or IV until blood counts recover.

Cohorts of 3-6 patients receive escalating doses of temozolomide until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.

Patients are followed at day 42, at 3 months, every 3 months for 2 years, every 4 months for 1 year, every 6 months for 1 year, and then annually thereafter.

PROJECTED ACCRUAL: A total of 18-30 patients will be accrued for this study. ;
