N2004-03: Intravenous Fenretinide in Treating Young Patients With Recurrent or Resistant Neuroblastoma

OBJECTIVES:

Primary

- To determine the maximum tolerated dose of fenretinide when given as a continuous
intravenous infusion in young patients with recurrent and/or resistant neuroblastoma.

- To define the toxicities of this drug in these patients.

- To determine the plasma pharmacokinetics of this drug in these patients.

Secondary

- To determine the response rate in patients treated with this drug.

- To determine the bioavailability of fenretinide in normal peripheral blood mononuclear
cells as a surrogate marker for drug bioavailability to tumor tissue.

OUTLINE: This is a multicenter study.

Patients receive fenretinide IV continuously over 120 hours on days 0-4. Treatment repeats
every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity.

Blood samples are collected periodically for pharmacokinetic analysis by high performance
liquid chromatography.

After completion of study treatment, patients are followed periodically.

DISEASE CHARACTERISTICS:

- Diagnosis of neuroblastoma either by histological confirmation and/or demonstration
of tumor cells in the bone marrow with increased urinary catecholamines

- Differentiating ganglioneuroblastoma allowed

- No histological evidence only of ganglioneuroma by tumor biopsy or bone
marrow biopsy

- High-risk disease meeting at least one of the following criteria:

- Recurrent/progressive disease at any time

- Refractory disease (i.e., less than a partial response to front-line therapy
that included ≥ 4 courses of chemotherapy)

- Persistent disease after at least a partial response to front-line therapy
(i.e., still has residual disease by MIBG, CT/MRI, or bone marrow biopsy)

- Biopsy of at least one residual site demonstrating viable neuroblastoma
required (tumor by bone marrow morphology is considered adequate
documentation of disease)

- Measurable disease meeting at least one of the following criteria:

- Measurable tumor on MRI or CT scan, defined as at least one unidimensionally
measurable lesion ≥ 20 mm by conventional techniques or ≥ 10 mm by spiral CT
scan

- For patients with persistent disease, a biopsy* of bone marrow or bone or
soft tissue site must have demonstrated viable neuroblastoma

- MIBG scan with positive uptake at a minimum of one site

- For patients with persistent disease, a biopsy* of a MIBG positive site
must have demonstrated viable neuroblastoma

- Bone marrow with tumor cells seen on routine morphology (not by NSE staining
only) of bilateral aspirate and/or biopsy of one bone marrow sample NOTE: *If
the lesion was irradiated, the biopsy must have been done at least 4 weeks after
completion of radiotherapy

- No CNS parenchymal or meningeal-based lesions

- Skull-based tumor lesions with or without intracranial extension are allowed
provided there are no neurologic signs or symptoms or hydrocephalus related to
the lesion

- Patients with a history of complete surgical resection of CNS lesions are
eligible provided there is no evidence of CNS lesions by MRI or CT scan at study
entry

- Patients with a history of CNS lesions must be off corticosteroid therapy for
CNS lesions for ≥ 4 weeks

- Total bilirubin ≤ 1.5 times normal for age

- ALT and AST ≤ 3 times normal for age

- Serum triglycerides < 300 mg/dL

- Serum calcium < 11.6 mg/dL

- Lipase normal for age

- PT/PTT ≤ 1.5 times upper limit of normal for age (without fresh frozen plasma
support; vitamin K allowed)

- Not pregnant or nursing

- Negative pregnancy test

- Fertile patients must use effective contraception prior to, during, and for 2 months
after completion of study treatment

- LVEF ≥ 55% by ECHO or MUGA scan OR fractional shortening ≥ 27% by ECHO

- No hematuria and/or proteinuria > 1+ on urinalysis

- No known history of allergy to egg products

- No known history of allergy to soy bean oil

- No skin toxicity > grade 1 per CTCAE v3

- Seizure disorder allowed if seizures are controlled on anticonvulsants and the
anticonvulsant(s) is not contraindicated

- Known genetic, metabolic, or psychiatric conditions, or other ongoing serious medical
issues must be approved by the study chair prior to study registration

PRIOR CONCURRENT THERAPY:

- Recovered from all prior chemotherapy, immunotherapy, or radiotherapy

- More than 3 weeks since prior myelosuppressive chemotherapy (4 weeks for
nitrosoureas) and/or biologic therapy without stem cell support

- More than 7 days since prior hematopoietic growth factors

- No prior radiotherapy to the only site of measurable disease unless there has been
subsequent disease progression at that site or a biopsy of that site showed viable
neuroblastoma ≥ 4 weeks after completion of radiotherapy

- Prior CNS irradiation allowed

- At least 2 weeks since prior small field (focal) radiotherapy

- At least 6 weeks since prior large field radiotherapy (i.e., total-body irradiation,
craniospinal radiotherapy, whole abdominal or total lung radiotherapy, or
radiotherapy to > 50% of marrow space)
