This NANT trial will determine the maximum tolerated dose (MTD) of autologous expanded natural killer (NK) cells when combined with standard dosing of dinutuximab and will assess the feasibility of adding lenalidomide at the recommended Phase II dose of the expanded NK cells with dinutuximab, for treatment of children with refractory or recurrent neuroblastoma.

Dinutuximab is a chimeric antibody against GD2, which is expressed on a majority of neuroblastoma cells. It has been shown to increase EFS and OS in patients with high-risk neuroblastoma when given after autologous stem cell transplant in combination with subcutaneous GM-CSF and intravenous IL-2, followed by isotretinoin. Lenalidomide has been studied in children with solid tumors and can safely be given to patients based on 2 prior trials in children. It was also shown to have immunomodulatory effects and is synergistic with dinutuximab. Lenalidomide is also an oral agent that can be given in the outpatient setting. Natural killer cells are lymphocytes of the innate immune system that have the ability to recognize and kill malignant cells, including neuroblastoma. Dinutuximab and lenalidomide both exert part of their anti-cancer effect through the activation of natural killer cells. Patients were given these in combination in the NANT 2011-04 study where the safety and immunomodulatory effect were established. The dose level proposed in this study is based off of these data. Natural killer cells are dysfunctional and low in number in many cancer patients, and number and function are further suppressed by chemotherapy and radiation. Investigators hypothesize that autologous NK cells can be expanded and activated ex vivo and readministered to restore number and function, and in combination with lenalidomide and dinutuximab will provide an anti-tumor effect in patients with relapsed or refractory neuroblastoma.
Investigators will determine the feasibility of centralized expansion, cryopreservation, and distribution of autologous NK cells. Investigators will then determine the maximum tolerated dose by assessing the toxicities of autologous expanded NK cells given with dinutuximab; by assessing the toxicities, cytokinetics and immunomodulatory effects, Investigators will select the recommended Phase II dose of the two-agent combination after dose escalation of the NK cells and then adding lenalidomide to the combination to establish the three-agent combination.
Cytokinetics (persistence of infused NK cells) and immune function studies will be required for all patients entered on this study. In addition to routine assessment of response, quantification of rare tumor cell detection in blood and bone marrow using TLDA will also provide another measure of possible anti-tumor efficacy to support the rationale for the final schedule chosen.

All patients must have at least one of the following
a) Recurrent/progressive disease: after the diagnosis of high risk neuroblastoma at any time prior to enrollment regardless of response to frontline therapy b) No prior history of recurrent/progressive disease since the diagnosis of high risk neuroblastoma b1) Refractory disease- a best overall response of no response/stable disease since diagnosis of high risk neuroblastoma and at least 4 cycles of induction therapy. No prior history of recurrent/progressive disease since the diagnosis of high risk neuroblastoma.
b2) Persistent disease- a best overall response of no partial response since diagnosis of high risk neuroblastoma and at least 4 cycles of induction therapy. No prior history of recurrent/progressive disease since the diagnosis of high risk neuroblastoma.
Patients must have at least ONE of the following (lesions may have received prior radiation therapy as long as they meet the other criteria listed below):
At least one soft tissue lesion that meets criteria for a TARGET lesion as defined by:
b1) MIBG avid. For patients with recurrent/progressive or refractory disease, no biopsy is required. For patients with persistent disease only: If a patient has only 1 or 2 MIBG avid lesions sites, then biopsy confirmation of neuroblastoma and/or ganglioneuroblastoma in at least one MIBG avid site present at time of enrollment is required to be obtained. If a patient has 3 or more MIBG avid lesions, then no biopsy is required.
b2) MIBG non avid tumors: Patients must have at least one FDG avid site and biopsy confirmation of neuroblastoma and/or ganglioneuroblastoma in at least one FDG-PET avid site present at the time of enrollment.
2. Patients must not have received the therapies indicated below after disease evaluation or within the specified time period prior to registration on this study as follows:
Cellular Therapy (e.g. modified T cells, NK cells, dentritic cells etc.):
must not have received within 3 weeks and resolution of all toxicities.
11) All patients must have adequate organ function defined as:
- Hematological Function:
Patients with known bone marrow metastatic disease will be eligible for study as long as they meet hematologic function criteria above.
Pulmonary Function: No dyspnea at rest, no oxygen requirement.
12) Reproductive Status: All post-menarchal females must have a negative beta-HCG. Males and females of reproductive age and childbearing potential must use effective contraception for the duration of their participation.
13) Patients with other ongoing serious medical issues must be approved by the study chairprior to registration.
14) Patients may not receive any other anti-cancer agents or radiotherapy while on protocol therapy.
