Clinical Trial 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.

Description:

Primary Objective:

• To evaluate day +35 ANC engraftment in autologous stem cell transplantation for high risk pediatric malignancies after stem cell selection and immunotherapy.

Secondary Objectives

• To estimate incidence of relapse, disease-free survival and overall survival.

• To characterize lymphocyte and hematopoietic reconstitution in these patients.

• To describe the characteristics of the stem cell and natural killer cell grafts.

• To estimate the overall survival of patients treated without stem cell manipulation or NK cell infusion due to off therapy criteria

Eligibility

The transplant recipient will be evaluated for eligibility at two time points during study participation. The first phase will be when the autologous stem cell product is collected.

• At least two weeks since receipt of any biological therapy, chemotherapy, and/or radiation therapy.

• Has recovered from all acute NCI Common Toxicity Criteria grade II-IV non-hematologic toxicities from prior therapy per the judgment of the PI.

• Shortening fraction greater than or equal to 25%.

• Creatinine clearance or glomerular filtration rate greater than or equal to 50 mL/min/1.73 m^2.

• Karnofsky or Lansky performance score of greater than or equal to 50.

• Has not received a prior hematopoietic stem cell transplant within 3 months.

• Has no known allergy to murine products or positive human anti-mouse antibody (HAMA)

• (Female only) Is not pregnant (negative serum or urine pregnancy test to be conducted within 7 days prior to admission for transplant).

• (Female only) Is not breastfeeding.

• Does not meet donation eligibility requirements as outlined by 21 CFR 1271 and agency guidance.

Inclusion criteria for haploidentical NK cell donor:

• At least 18 years of age.

• Partially HLA matched family member.

• Human immunodeficiency virus (HIV) negative.

• (Female only) Is not pregnant (negative serum or urine pregnancy test to be conducted within 7 days prior to enrollment).

• (Female only) Is not breastfeeding.

Intervention

Biological:
• CD133+ selected autologous stem cell infusion
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.
• IL-2
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.
• hu14.18K322A
Participants with neuroblastoma (Group A) will receive hu14.18K322A intravenously (IV).

Drug:
• Busulfan
Given IV - Group A only.
• Melphalan
Given IV - All groups.

Biological:
• GM-CSF
Given SQ - All groups.

Drug:
• Bendamustine
Given IV - Group B only.
• Etoposide
Given IV - Group B and Group C. In case of etoposide reactions, etoposide phosphate will be given.
• Cytarabine
Given IV - Group B only.
• Carboplatin
Given IV - Group C only.

Device:
• Haploidentical natural killer cell infusion
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.

Biological:
• G-CSF
Given SQ - All Groups.

Drug:
• Etoposide phosphate
In case of etoposide reactions, etoposide phosphate will be given IV. - Group B and Group C only.

Device:
• CliniMACS
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.

Primary	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.	Day 35 post transplant
