Vorinostat and Isotretinoin in Treating Patients With High-Risk Refractory or Recurrent Neuroblastoma

This phase I trial is studying the side effects and the best dose of vorinostat when given together with isotretinoin to see how well it works in treating patients with high-risk refractory or recurrent neuroblastoma. Vorinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Isotretinoin may help vorinostat work better by making tumor cells more sensitive to the drug. Giving vorinostat together with isotretinoin may be an effective treatment for neuroblastoma.

Stanford is currently not accepting patients for this trial.

      including a minimum of 4 cycles of chemotherapy); no biopsy is required to
      document eligibility

      - 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 metaiodobenzylguanidine [MIBG] scan, computed tomography
      [CT]/magentic resonance imaging [MRI], or bone marrow aspirates/biopsies);
      patients in this category are REQUIRED to have histologic confirmation of viable
      neuroblastoma from at least one residual site; tumor seen on routine bone marrow
      morphology is sufficient; bone marrow immunocytology alone is not sufficient for

   patients entered in the Expansion Cohort) :

      - Measurable tumor on MRI or CT scans or X-ray; measurable is defined >= 20 mm in

      viable neuroblastoma; if the lesion was radiated, then biopsy must be done >= 4
      weeks after radiation completed

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

   has demonstrated clear progression after radiation

   - A minimum of 12 weeks prior to start of vorinostat is required following prior large
   field radiation therapy (i.e. total body irradiation, craniospinal, whole abdominal,
   total lung, > 50% marrow space), otherwise a minimum of 6 weeks must have elapsed if
   other substantial bone marrow (BM) radiation

   - Patients are eligible 6 weeks after date of autologous stem cell infusion following
   myeloablative therapy (timed from start of vorinostat); patients are eligible 6 weeks
   after date of allogeneic stem cell transplant if without evidence of active graft
   versus host disease; patients receiving an autologous stem cell infusion to support
   non-myeloablative therapy are eligible at any time as long as they meet the
   hematologic and other organ function criteria for eligibility

   - A minimum of 6 weeks must have elapsed after 131I-MIBG therapy (timed from start of

   - Prolongation of the corrected QT (QTc) interval has been rarely observed in adults
   receiving vorinostat; patients must not be receiving azole anti-fungal therapy at the

   as they meet hematologic function criteria; patients with marrow disease are not
   evaluable for hematologic toxicity; if dose limiting hematologic toxicity occurs in
