N99-02: Melphalan and Buthionine Sulfoximine (BSO)
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with bone marrow or 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 melphalan and buthionine sulfoximine followed by bone marrow or peripheral stem cell transplantation in treating children who have resistant or recurrent neuroblastoma.
Drug: buthionine sulfoximine
Procedure: Peripheral blood stem cell infusion
|Study Design:||Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Modulation of Intensive Melphalan (L-PAM) by Buthionine Sulfoximine (BSO) Autologous Stem Cell Support for Resistant or Recurrent High-Risk Neuroblastoma (IND 69-112)|
- To determine the maximum tolerated dose(MTD) and the toxicities of Melphalan (L-PAM) escalated in the presence of Buthionine sulphoxamine (BSO) and followed by autologous stem cells rescue for pediatric patients with high-risk neuroblastoma. [ Time Frame: Within 4 weeks of completion of BSO/L-PAM therapy ] [ Designated as safety issue: Yes ]
- To determine the pharmacokinetics (PK) of BSO and L-PAM in pediatric patients. [ Time Frame: For BSO: just before start of therapy to 8 hours post end of 72 infusion. For L-PAM : just before start of 2nd dose to 4 hours post. ] [ Designated as safety issue: Yes ]Collection of blood samples for PK studies is optional and not required for study entry.
- To determine the response rate of recurrent high risk neuroblastoma to BSO/LPAM within the confines of a phase I study. [ Time Frame: 84 days after completion of therapy with BSO/L-PAM and Stem cell re-infusion. ] [ Designated as safety issue: No ]
- To determine the glutathione content of peripheral blood leucocytes in patients receiving BSO and L-PAM. [ Time Frame: For BSO: just before start of therapy to 8 hours post end of 72 infusion. For L-PAM : just before start of 2nd dose to 4 hours post. ] [ Designated as safety issue: No ]Collection of blood samples for biologic studies is optional and not required for study entry.
- To determine the number of days to ANC =/> 500 for three days and platelets =/> 20,000 for three days (without transfusion) for this regimen. [ Time Frame: Maximum 56 days after completion of therapy with BSO/L-PAM and Stem cell re-infusion. ] [ Designated as safety issue: Yes ]

Drug: buthionine sulfoximine
- Autologous Bone marrow Transplant
- Determine the maximum tolerated dose of melphalan when combined with buthionine sulfoximine and followed by autologous bone marrow or peripheral blood stem cell support in children with resistant or recurrent high-risk neuroblastoma.
- Assess the toxic effects of this regimen in these patients.
- Determine the pharmacokinetics of this regimen in these patients.
- Determine the response rate of patients treated with this regimen.
OUTLINE: This is a multicenter, dose-escalation study of melphalan.
Patients receive buthionine sulfoximine IV as a bolus over 30 minutes followed by a 72-hour continuous infusion beginning on day -4; melphalan IV over 15 minutes on days -3 and -2; autologous peripheral blood stem cells or bone marrow IV over 15-30 minutes on day 0; and filgrastim (G-CSF) subcutaneously or IV once daily beginning on day 0 and continuing until blood counts recover.
Cohorts of 3-6 patients receive escalating doses of melphalan 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 84 days and then 2 months later if there is a complete and/or partial response. Patients who continue therapy on other protocols are followed before starting the new therapy. All patients are followed for life for any delayed toxic effects to protocol therapy and secondary malignancies.
PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study within 2-3 years.
