N2004-04: Fenretinide LXS in Treating Patients With Recurrent, Refractory, or Persistent Neuroblastoma

RATIONALE: Drugs used in chemotherapy, such as fenretinide LXS, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.

PURPOSE: This phase I trial is studying the side effects and best dose of fenretinide LXS in treating patients with recurrent, refractory, or persistent neuroblastoma.

Stanford is currently not accepting patients for this trial.

Children's Hospital Los Angeles

Collaborator: National Cancer Institute (NCI)

  • Drug: fenretinide lipid matrix
  • Drug: ketoconazole
  • Other: laboratory biomarker analysis

   the bone marrow with increased urinary catecholamines

   - High-risk disease, as evidenced by ≥ 1 of the following:

      - Recurrent/progressive disease at any time

      - Refractory disease (i.e., less than a partial response to frontline therapy)

         - No biopsy required

      - Persistent disease after at least a partial response to frontline therapy (i.e.,
      patient has had at least a partial response to frontline therapy but still has
      residual disease by MIBG scan, CT scan/MRI, or bone marrow)

         - Biopsy of at least one residual site demonstrating viable neuroblastoma

   - Patients must have ≥ 1 of the following sites of disease:

      - Measurable tumor, defined as ≥ 2 cm in at least 1 dimension by MRI, CT scan, or
      x-ray OR ≥ 1 cm in at least 1 dimension by spiral CT scan

         - For persistent disease, a biopsy of bone and/or soft tissue site seen on
         CT/MRI must have been done to demonstrate viable neuroblastoma

            - If lesion was irradiated, biopsy must be done ≥ 2 weeks after radiation

      - MIBG scan with positive uptake at ≥ 1 site

         - For persistent disease, a biopsy of an MIBG-positive site must have been
         done to demonstrate viable neuroblastoma

            - If lesion was irradiated, biopsy must be done at least 2 weeks after
            radiation completed

      - Tumor cells on routine morphology (not by neuron-specific enolase staining only)
      of bilateral bone marrow aspirate and/or biopsy on one bone marrow sample

   - Patients enrolled in group I may have had a prior relapse or progression, even if they
   have no measurable or evaluable tumor sites at time of study entry, including any of
   the following:

      - No tumor sites on all evaluations

      - Non-measurable tumor on MRI /CT scan and/or measurable tumor on CT/MRI that was
      previously irradiated

      - MIBG-avid site that was previously irradiated

   - No CNS parenchymal or meningeal-based lesions

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

   - Hemoglobin ≥ 8.0 g/dL (transfusion allowed)

   - Platelet count ≥ 50,000/mm^3 (transfusion independent [ i.e., ≥ 1 week since last
   platelet transfusion])

   - Creatinine ≤ 1.5 times normal for age as follows:

      - No greater than 0.8 mg/dL (for patients 5 years of age and under)

      - No greater than 1.0 mg/dL (for patients 6-10 years of age)

      - No greater than 1.2 mg/dL (for patients 11-15 years of age)

      - No greater than 1.5 mg/dL (for patients over 15 years of age)

   - Ejection fraction ≥ 55% by echocardiogram or MUGA OR fractional shortening ≥ 27% by

   - Bilirubin ≤ 1.5 times normal

   - ALT and AST ≤ 3 times normal (for ALT, upper limit of normal is 45 U/L)

   - Triglycerides < 300 mg/dL (fasting or random plasma test)

   - Calcium < 11.6 mg/dL

   - Not pregnant or nursing

   - Negative pregnancy test

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

   - Normal lung function (i.e., no dyspnea at rest or oxygen requirement)

   - Seizure disorder allowed provided seizures are controlled on anticonvulsants that are
   not contraindicated

   - More than 3 weeks since prior myelosuppressive chemotherapy and/or biologics (4 weeks
   for nitrosoureas)

   site of measurable disease
