Summary

This phase II trial studies how well irinotecan hydrochloride, temozolomide, and dinutuximab work with or without eflornithine in treating patients with neuroblastoma that has come back (relapsed) or that isn't responding to treatment (refractory). Drugs used in chemotherapy, such as irinotecan hydrochloride and temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as dinutuximab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. Eflornithine blocks the production of chemicals called polyamines that are important in the growth of cancer cells. Giving eflornithine with irinotecan hydrochloride, temozolomide, and dinutuximab, may work better in treating patients with relapsed or refractory neuroblastoma.

Objectives

PRIMARY OBJECTIVE:
I. To determine whether administration of eflornithine hydrochloride (eflornithine [DFMO]) in combination with dinutuximab, irinotecan hydrochloride (irinotecan) and temozolomide results in an improved response rate compared to dinutuximab, irinotecan and temozolomide in patients with relapsed or refractory neuroblastoma and therefore is a therapeutic regimen worthy of further testing in patients with newly-diagnosed high-risk neuroblastoma.

SECONDARY OBJECTIVES:
I. To compare progression-free survival and overall survival between patients receiving dinutuximab, irinotecan and temozolomide with and without the addition of DFMO.
II. To define the toxicity profile of DFMO administered with dinutuximab, irinotecan and temozolomide.

EXPLORATORY OBJECTIVES:
I. To characterize the immune and cytokine profiles of patients treated with DFMO/chemotherapy/dinutuximab combination and correlate with response to therapy.
II. To evaluate GD2 levels in tumor cells from patient bone marrow samples and correlate with response to therapy.
III. To explore whether the addition of DFMO to the dinutuximab and chemotherapy backbone affects pain as determined by patient report and opiate usage.

OUTLINE: Patients are randomized to 1 of 2 regimens.

REGIMEN A: Patients receive temozolomide orally (PO), via nasogastric (NG), or gastric (G) tube on days 1-5, irinotecan hydrochloride intravenously (IV) over 90 minutes on days 1-5, dinutuximab IV over 10-20 hours on days 2-5, and sargramostim subcutaneously (SC) or IV over 2 hours on days 6-12 of a 21-day cycle. Treatment repeats every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.

REGIMEN B: Patients receive eflornithine PO, via NG, or G tube on days -6 to 7 and days 15-21 of cycle 1 and days 1-7 and 15-21 of subsequent cycles, temozolomide PO, via NG, or G tube on days 1-5, irinotecan hydrochloride intravenously (IV) over 90 minutes on days 1-5, dinutuximab IV over 10-20 hours on days 2-5, and sargramostim SC or IV over 2 hours on days 6-12. Treatment lasts 28 days for cycle 1 and then every 21 days for subsequent cycles up to 6 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and periodically for 5 years.

Eligibility

  1. Patients must have had histologic verification of neuroblastoma or ganglioneuroblastoma or demonstration of neuroblastoma cells in the bone marrow with elevated urinary catecholamines (i.e. > 2 x upper limit of normal [ULN]), at the time of initial diagnosis.
  2. For the purposes of this study, aggressive multidrug chemotherapy is defined as chemotherapy including 2 or more agents that must include an alkylating agent and a platinum-containing compound as intended to treat high-risk disease. The doses of chemotherapy must be comparable to those used in frontline high-risk neuroblastoma therapies (examples include A3973, ANBL0532, ANBL09P1, ANBL12P1, and ANBL1531). Patients must have ONE of the following: * First episode of recurrent high-risk disease following completion of aggressive multi-drug frontline high-risk therapy. * First episode of progressive high-risk disease during aggressive multi-drug frontline therapy. * Primary resistant/refractory disease (less than partial response by International Neuroblastoma Response Criteria [INRC]) detected at the conclusion of at least 4 cycles of aggressive multidrug induction chemotherapy on or according to a high-risk neuroblastoma protocol (examples include A3973, ANBL0532, ANBL09P1, ANBL12P1, ANBL1531, etc.).
  3. Patients must have at least ONE of the following at the time of enrollment: * Measurable tumor on magnetic resonance imaging (MRI) or computed tomography (CT) scan. Measurable is defined as >= 10 mm in at least one dimension on spiral/helical CT that is metaiodobenzylguanidine (MIBG) avid or demonstrates increased fludeoxyglucose F-18 (FDG) uptake on positron emission tomography (PET) scan. * MIBG-avid lesion detected on MIBG scan with positive uptake at a minimum of one site. This site must represent disease recurrence after completion of therapy, progressive disease on therapy, or refractory disease during induction. * Patients with resistant/refractory soft tissue disease that is not MIBG avid or does not demonstrate increased FDG uptake on PET scan must undergo biopsy to document the presence of viable neuroblastoma. Biopsy is not required for patients who have a new site of soft tissue disease (radiographic evidence of disease progression) regardless of whether progression occurs while receiving therapy or after completion of therapy. * Patients with bone marrow disease only will be eligible if they have more than 5% disease involvement (documented neuroblastoma cells) in at least one sample from bilateral bone marrow biopsies. * Note: Patients with elevated catecholamines (i.e. > 2 x ULN) only are NOT eligible for this study.
  4. Patients must have a performance status corresponding to Eastern Cooperative Oncology Group (ECOG) scores of 0, 1 or 2. Use Karnofsky for patients > 16 years of age and Lansky for patients =< 16 years of age.
  5. Primary refractory/resistant patients must have received at least 4 cycles of frontline high-risk chemotherapy. Frontline therapy may also have included surgery, chemotherapy, autologous stem cell transplantation (SCT) +/- MIBG, immunotherapy, radiotherapy, and retinoids but must NOT have received second line therapy for resistant/refractory, relapsed, or progressive disease. Patients who received intensified therapy for poor induction response or refractory disease (e.g. MIBG) will be considered to have received second line therapy and will not be eligible.
  6. At least 14 days must have elapsed since completion of myelosuppressive therapy.
  7. Anti-cancer agents not known to be myelosuppressive (e.g. not associated with reduced platelet or absolute neutrophil count [ANC] counts): >= 7 days after the last dose of agent.
  8. Antibodies: >= 21 days must have elapsed from infusion of last dose of antibody, and toxicity related to prior antibody therapy must be recovered to grade =< 1.
  9. No interim time prior to study entry is required following prior radiation therapy (RT) for non-target lesions. However, patients must not have received radiation for a minimum of 4 weeks prior to study entry at the site of any lesion that will be identified as a target lesion to measure tumor response. Lesions that have been previously radiated cannot be used as target lesions unless there is radiographic evidence of progression at the site following radiation or a biopsy done following radiation shows viable neuroblastoma. Palliative radiation while on study is not permitted.
  10. Patients are eligible >= 6 weeks after autologous stem cell transplants or stem cell infusions (including stem cell infusions given as supportive care following 131 I-MIBG therapy) as long as hematologic and other eligibility criteria have been met.
  11. Patients are eligible >= 6 weeks after therapeutic 131 I-MIBG provided that all other eligibility criteria are met.
  12. Subjects who have previously received anti-GD2 monoclonal antibodies with or without retinoids for biologic therapy are eligible unless they have had progressive disease while receiving prior anti-GD2 therapy or progressed/relapsed within 3 months of receiving anti-GD2 therapy. However, eligible patients may NOT have received anti-GD2 monoclonal antibodies in combination with chemotherapy.
  13. Subjects who have received autologous marrow infusions or autologous stem cell infusions that were purged using monoclonal antibody linked to beads are eligible.
  14. Subjects who have previously received DFMO are eligible for this study provided they have not had progressive disease while receiving DFMO or progressed/relapsed within 3 months of completing DFMO.
  15. Patients must not have received long-acting myeloid growth factors (e.g. pegfilgrastim) within 14 days of entry on this study. Seven days must have elapsed since administration of a short-acting myeloid growth factor.
