N2001-02: I-MIBG With Intensive Chemotherapy and Autologous Stem Cell Rescue for High-Risk Neuroblastoma

Summary

RATIONALE: Radioactive drugs, such as iodine I 131 metaiodobenzylguanidine, may carry radiation directly to tumor cells and not harm normal cells. Drugs used in chemotherapy, such as carboplatin, etoposide, and melphalan, 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. An autologous peripheral stem cell or bone marrow transplant may be able to replace blood-forming cells that were destroyed by chemotherapy and radiation therapy. Giving iodine I 131 metaiodobenzylguanidine and combination chemotherapy with an autologous peripheral stem cell or bone marrow transplant may allow more chemotherapy to be given so that more tumor cells are killed. Giving radiation therapy after an autologous peripheral stem cell or bone marrow transplant may kill any remaining tumor cells.

PURPOSE: This phase II trial is studying how well giving iodine I 131 metaiodobenzylguanidine together with combination chemotherapy and radiation therapy works in treating patients who are undergoing an autologous peripheral stem cell or bone marrow transplant for relapsed or refractory neuroblastoma.

Conditions

• Neuroblastoma

Interventions

BIOLOGICAL

Filgrastim

Filgrastim 5 micrograms/kg/day S.C. or IV will be given daily beginning on Day 0. The first dose should begin four hours after the stem cell infusion is completed. Filgrastim will continue daily until the ANC \>=1500/uL for three consecutive days.

DRUG

Carboplatin

The carboplatin will be administered as a continuous IV infusion Day - 7 through Day - 4, with dosing based upon pretreatment GFR levels. The carboplatin should be diluted to a concentration of 0.3 mg/ml in D5W 0.45NS and infused concomitantly with etoposide through the same central venous catheter using a "Y" connector; a controlled rate infusion pump is used for each arm of the "Y".

DRUG

Etoposide

The etoposide shall be administered day -7 through day -4 via continuous intravenous infusion over 96 hours. For patients with a corrected GFR \>= 100 ml/min/1.72 m\^2, a dose of 300 mg/m\^2/day (10 mg/kg/day if child is \< 12 kg) shall be given. For patients with a corrected GFR 60-99 ml/min/1.72 m\^2, the etoposide will be administered at a dose of 160 mg/m\^2/day (5.3 mg/kg/day). The etoposide will be diluted in D5W 0.45%NS at a concentration of \< 0.4 mg/ml. Etoposide should not be mixed with carboplatin, but administered using a Y-connector.

DRUG

Melphalan

For patients in either the normal GFR strata (\>=100 ml/min/1.73 m\^2), or reduced GFR strata (60-99 ml/min/1.73m\^2), melphalan shall be administered at a dose of 60 mg/m\^2/day (2 mg/kg/day if child is \< 12 kg) on day -7, -6, and -5 of study. The melphalan should be infused at a rate of less than 10 mg/minute, and should complete within 1 hour of reconstitution each day. The melphalan should be diluted in 0.9% NaCl at a concentration \< 2 mg/ml. The total dosage of melphalan to be administered will be 180 mg/m\^2.

PROCEDURE

Peripheral blood stem cell infusion

Stem cells or marrow will be infused on day 0 of study therapy. Where the DMSO concentration in the stem cell product would exceed accepted level for infusion within a 24 hour period, stem cell products may be infused over two days to meet this standard. For purged PBSC: A minimum of 2.0 x 10\^6 viable CD34+ cells/kg must be available. For unpurged PBSC, a minimum of 2.0 x 10\^6 viable CD34+ cells/kg must be available. Having a back-up of 2.0 x 10\^6 viable CD34+ cells/kg purged or unpurged PBSC is recommended but not required. For purged bone marrow, a minimum of 1.5 x10\^8 mononuclear cells/kg must be available.

RADIATION

131I-MIBG

Therapeutic 131I MIBG will be synthesized by Draximage Canada.with specific activity between 15 and 25mCi/ml. Radiopurity will be initially determined by Draximage, prior to shipment to participating centers. Free radioiodide content must then be rechecked at the treating center prior to infusion using HPLC or Sep-Pac methodology.

RADIATION

Radiation therapy

Local irradiation is to be given to previously non-irradiated primary and metastatic sites of disease. Local irradiation should not start till the patient is medically stable, has an ANC \> 1000/uL, platelets \> 30,000 / uL, and is \> 42 days post transplant. Recommended radiation guidelines consist of 2160 cGy total, given over 12 days using a single 180 cGy fraction/day. Any delay in local radiation that would extend treatment beyond day +84 should be discussed with the study chair. Local radiation will be administered at a participating NANT member site.
