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.

Description

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.

Inclusion Criteria

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
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.)
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

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

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

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
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
Patients are eligible >= 6 weeks after therapeutic 131 I-MIBG provided that all other eligibility criteria are met

Exclusion Criteria

Men and women of childbearing potential and their partners must agree to use adequate contraception while enrolled on this study. Based on the established teratogenic potential of alkylating agents, pregnant women will be excluded from this study.

The only exception is for patients known to require 2 mg/kg or less of hydrocortisone (or an equivalent dose of an alternative corticosteroid) as premedication for blood product administration in order to avoid allergic transfusion reactions. The use of conventional doses of inhaled steroids for the treatment of asthma is permitted, as is the use of physiologic doses of steroids for patients with known adrenal insufficiency
