Assessment method [1]
0
0
The percentage of patients who are responders will be tabulated, including a 95% confidence interval on the response rate. Responders are defined as patients who achieve a best overall response of complete response (CR), very good partial response (VGPR), or partial response (PR) per the International Neuroblastoma Response Criteria (INRC). Per INRC: CR= Disappearance of all target lesions. No evidence of tumor at any site; VGPR= \>90% decrease of the disease measurement for CT/MRI target lesions. All pre-existing bone lesions with CR by MIBG; MIBG scan can be stable disease (SD) or CR in soft tissue lesions corresponding to lesions on CT/MRI. CR in bone marrow. No new sites of tumor; PR= \>=30% decrease in the disease measurement for CT/MRI target lesions. Bone marrow with CR. MIBG with either PR/CR in bone lesions; MIBG may be SD or CR in soft tissue lesions corresponding to lesions on CT/MRI. Homovanillic acid (HVA)/Vanillylmandelic acid (VMA) may still be elevated.

Eligibility
Key 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; patients must have ONE of the following:
* First episode of recurrent disease following completion of aggressive multi-drug frontline therapy
* First episode of progressive disease during aggressive multi-drug frontline therapy
* Primary resistant/refractory disease (less than partial response by 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, etc.)
* Patients must have at least ONE of the following:
* Measurable tumor on magnetic resonance imaging (MRI), computed tomography (CT) scan obtained within 3 weeks prior to study entry; measurable is defined as >= 10 mm in at least one dimension on spiral/helical CT that is metaiodobenzylguanidine (MIBG) avid or demonstrates increased fludeoxyglucose (FDG) uptake on positron emission tomography (PET) scan
* MIBG scan obtained within 3 weeks prior to study entry 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 new site of soft tissue disease (radiographic evidence of disease progression) regardless of whether progression occurs while receiving therapy or after completion of therapy
* Note: Patients with elevated catecholamines (i.e., > 2 x ULN) only or bone marrow disease only are NOT eligible for this study
* 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
* Patients must have received frontline therapy (including surgery, chemotherapy, autologous stem cell transplant [SCT] +/- MIBG, immunotherapy, radiotherapy, and retinoids) but may NOT have received second line chemotherapy for resistant/refractory, relapsed disease or progressive disease
* At least 14 days must have elapsed since completion of myelosuppressive therapy
* At least 7 days must have elapsed since the completion of therapy with a non-myelosuppressive biologic agent or retinoid
* 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 is allowed to sites that will not be used to measure response during this study
* Patients are eligible >= 6 weeks after autologous stem cell transplants or stem cell infusions as long as hematologic and other eligibility criteria have been met
* Patients are eligible >= 6 weeks after therapeutic 131I-MIBG provided that all other eligibility criteria are met
* Subjects who have previously received anti-GD2 monoclonal antibodies for biologic therapy or for tumor imaging are eligible unless they have had progressive disease while receiving prior anti-GD2 therapy; subjects who have received autologous marrow infusions or autologous stem cell infusions that were purged using monoclonal antibody linked to beads, but no other form of anti-GD2 monoclonal antibody, are eligible
* Patients must not have received long-acting myeloid growth factors (e.g., Neulasta) within 14 days of entry on this study; seven days must have elapsed since administration of a short acting myeloid growth factor
* Peripheral absolute neutrophil count (ANC) >= 750/uL
* Platelet count >= 75,000/uL (transfusion independent)
* Patients known to have bone marrow involvement with neuroblastoma are eligible provided that minimum ANC and platelet count criteria are met but are not evaluable for hematological toxicity
* Creatinine clearance or estimated radioisotope glomerular filtration rate (GFR) >= 70 mL/min/1.73 m^2 or

* Age 2 to < 6 years: 0.8 for males, 0.8 for females
* Age 6 to < 10 years: 1 for males, 1 for females
* Age 10 to < 13 years: 1.2 for males, 1.2 for females
* Age 13 to < 16 years: 1.5 for males, 1.4 for females
* Age >= 16 years: 1.7 for males, 1.4 for females
* Total bilirubin =< 1.5 x ULN for age AND
* Serum glutamate pyruvate transaminase (SGPT) (alanine aminotransferase [ALT]) =< 5.0 x ULN for age (=< 225 U/L); for the purpose of this study, the ULN for SGPT is 45 U/L
* Adequate central nervous system function defined as:
* Patients with a history of central nervous system (CNS) disease must have no clinical or radiological evidence of CNS disease at the time of study enrollment
* Patients with seizure disorders may be enrolled if seizures are well controlled on anticonvulsants

* Shortening fraction of >= 27% by echocardiogram (ECHO) OR
* Ejection fraction >= 50% by ECHO or gated radionuclide study
* Adequate coagulation defined as:
* Prothrombin time (PT) =< 1.2 x upper limit of normal
* Adequate pulmonary function defined as:
* No evidence of dyspnea at rest, no exercise intolerance, no chronic oxygen requirement, and room air pulse oximetry > 94% if there is a clinical indication for pulse oximetry; normal pulmonary function tests in patients who are capable of cooperating with testing (including diffusion capacity of the lung of carbon monoxide [DLCO]) are required if there is a clinical indication for determination; for patients who do not have respiratory symptoms, full pulmonary function tests (PFTs) are NOT required

Key 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; female patients who are lactating must agree to stop breastfeeding or will otherwise be excluded from this study; females of childbearing potential must have a negative pregnancy test to be eligible for this study

Summary
Brief summary
This randomized phase II trial studies how well irinotecan hydrochloride and temozolomide with temsirolimus or dinutuximab work in treating younger patients with neuroblastoma that has returned or does not respond to treatment. 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. Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as dinutuximab, may find tumor cells and help kill them or carry tumor-killing substances to them. It is not yet known whether giving irinotecan hydrochloride and temozolomide together with temsirolimus or dinutuximab is more effective in treating neuroblastoma.
