Brief Summary
This is a pilot clinical trial investigating the addition of haploidentical natural killer cell infusion to autologous stem cell transplantation. This intervention will be evaluated in children with high-risk solid tumors for whom autologous transplantation is indicated. Natural killer cells from a haploidentical family member will be given after high dose chemotherapy and positively selected autologous stem cells. In patients with neuroblastoma, the anti-GD2 antibody hu14.18K322A will also be given. The effect on normal hematopoietic cell recovery will be evaluated and survival of children treated with this approach will be determined. The investigators expect to enroll 36 participants. Haploidentical family members (donors) will also be recruited to provide natural killer cells.

Outcome Measures
Primary Outcomes (1)
Percent of participants with positive ANC engraftment
Feasibility will be determined based on ANC engraftment defined as ANC ≥500/mm\^3 for 3 consecutive tests performed on different days evaluated before day 35 post-transplant. If the study is considered feasible, the ANC engraftment rate will be 100% (95% Blyth-Still-Casella (BSC) CI: 76.45%-100%) without any failure, 92% (BSC 95% CI: 65.11%-99.57%) with 1 failure, and 83% (BSC 95% CI: 55%-96.95%) with 2 failures. In addition, if more than 2 (≥ 3) on-therapy patients die due to any protocol treatment-related causes during the first 12 months post-transplant across all groups (3 deaths among 36 participants), the study will be stopped. Deaths due to treatment not specified in this protocol will not be included in evaluation of this stopping rule.

Study Arms (3)
Group A: Neuroblastoma
EXPERIMENTALAll participants first receive standard of care high-dose chemotherapy specific to their tumor type. Group A participants receive busulfan, melphalan, CD133+ selected autologous stem cell infusion, hu14.18K322A, IL-2, haploidentical natural killer cell infusion, G-CSF, and GM-CSF. Cells for infusion are prepared using the CliniMACS System.
Group B: Lymphoma
EXPERIMENTALAll participants first receive standard of care high-dose chemotherapy specific to their tumor type. Group B participants receive bendamustine, etoposide (or etoposide phosphate), cytarabine, melphalan, CD133+ selected autologous stem cell infusion, IL-2, haploidentical natural killer cell infusion, G-CSF, and GM-CSF. Cells for infusion are prepared using the CliniMACS System.
Group C: High-Risk Tumors
EXPERIMENTALAll participants first receive standard of care high-dose chemotherapy specific to their tumor type. Group C participants receive melphalan, etoposide (or etoposide phosphate), carboplatin, CD133+ selected autologous stem cell infusion, IL-2, haploidentical natural killer cell infusion, G-CSF, and GM-CSF. Cells for infusion are prepared using the CliniMACS System.
Interventions
Hematopoietic stem cells will be collected from children with high-risk solid tumors. After collection, they will be immuno-magnetically selected using CD133 as a marker in efforts to reduce tumor cell contamination in the stem cell graft. After high dose chemotherapy, those selected stem cells will be infused, followed shortly thereafter by an infusion of haploidentical natural killer cells.
Following infusion of haploidentical natural killer cells, interleukin-2 (IL-2) subcutaneously (SQ) will be given to support the in vivo survival of donor NK cells.
Participants with neuroblastoma (Group A) will receive hu14.18K322A intravenously (IV).
Given IV - All groups.
Given SQ - All groups.
Given IV - Group B only.
Given IV - Group B and Group C. In case of etoposide reactions, etoposide phosphate will be given.
Given IV - Group C only.
NK cell product will be collected from donors using leukapheresis procedures. The autologous hematopoietic stem cell graft product will be positively selected using the investigational CliniMACS device and CD133 Microbead reagent. Following standard laboratory procedures, the NK cell product will be enumerated and assessed for viable cell content. NK cells will be infused by slow IV push over 3 to 15 minutes immediately after processing, evaluation and release testing.
Given SQ - All Groups.
In case of etoposide reactions, etoposide phosphate will be given IV. - Group B and Group C only.
The mechanism of action of the CliniMACS Cell Selection System is based on magnetic-activated cell sorting (MACS). The CliniMACS device is a powerful tool for the isolation of many cell types from heterogeneous cell mixtures, (e.g. apheresis products). These can then be separated in a magnetic field using an immunomagnetic label specific for the cell type of interest, such as CD3+ human T cells.
Eligibility Criteria
You may qualify if:
- Less than or equal to 21 years of age.
- Malignancy at high risk of treatment failure for which autologous hematopoietic stem cell transplantation is considered within standard practice.
- Group A: High-risk neuroblastoma
- Group B: Recurrent or refractory Hodgkin lymphoma; recurrent or refractory non-Hodgkin lymphoma
- Group C: High-risk, recurrent or metastatic sarcoma; recurrent or advanced stage Wilms tumor; desmoplastic small round cell tumor; metastatic or recurrent retinoblastoma, high-risk germ cell tumors, and high-risk brain tumors
- Sarcoma or Wilms tumor diagnosis (Group C) will require evaluation by physician in the St. Jude Solid Tumor Division, other than the referring physician, attesting that autologous SCT provides the prospect of direct benefit for the participant.
- Has a potentially suitable human leukocyte antigen (HLA) haploidentical donor available.
- Research participant or legal guardian/representative must be willing to give written informed consent
- Does not have any active or prior malignant or pre-malignant condition of the bone marrow, excluding metastasis of the primary malignancy.
- Has no known allergy to murine products or positive human anti-mouse antibody (HAMA).
- (Female only) Negative serum or urine pregnancy test (to be conducted within 7 days prior to enrollment).
- (Female only) Not breastfeeding.
- Has a confirmed suitable HLA haploidentical donor available.
- Previously collected autologous stem cell product met the minimum collection target and minimum infusion target as described in the protocol.
- At least two weeks since receipt of any biological therapy, chemotherapy, and/or radiation therapy.
