Combination Chemotherapy and Peripheral Stem Cell Transplantation in Treating Patients With Recurrent or Refractory Solid Tumors
Recruitment status was Active, not recruiting
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell 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 combination chemotherapy and peripheral stem cell transplantation in treating patients who have recurrent or refractory solid tumors.
Unspecified Childhood Solid Tumor, Protocol Specific
Drug: topotecan hydrochloride
Procedure: peripheral blood stem cell transplantation
|Study Design:||Primary Purpose: Treatment|
|Official Title:||A Phase I Study of Thiotepa in Combination With Carboplatin and Topotecan With Peripheral Blood Progenitor Cell Support for the Treatment of Children With Recurrent or Refractory Solid Tumors.|
|Study Start Date:||July 1997|
- Determine the maximum tolerated dose of thiotepa in combination with carboplatin and topotecan with peripheral blood stem cell transplantation in patients with recurrent or refractory pediatric solid tumors.
- Determine the toxicity of this regimen in these patients.
OUTLINE: This is a dose escalation study of thiotepa.
Patients may receive 2 courses of mobilization comprising cyclophosphamide and etoposide with filgrastim (G-CSF) support and peripheral blood stem cell (PBSC) collection.
Patients receive thiotepa IV over 2 hours on days 0 and 1; topotecan IV over 30 minutes on days 0-4; and carboplatin IV over 2 hours on days 2 and 3. Patients also receive G-CSF beginning on day 5, 24-36 hours following the last dose of topotecan. PBSC are reinfused on day 6 (36-48 hours following the last dose of topotecan) of each course of therapy. Patients receive 3 courses of therapy.
Cohorts of 3-6 patients receive escalating doses of thiotepa until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity.
Patients are followed at 1 and 2 years.
PROJECTED ACCRUAL: A maximum of 24 patients will be accrued into this study.
