Study Overview
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.
Detailed 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

Outcomes
Primary Outcomes
Percent of participants with positive ANC engraftment
Time Frame: Day 35 post transplant
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.
Secondary Outcomes
- Overall survival(Up to one year after transplantation)
- Disease-free survival(Up to one year after transplantation)
- Lymphocyte and hematopoietic reconstitution(Up to one year after transplantation)
- Characteristics of the stem cell grafts(Up to one year after transplantation)
- Characteristics of the natural killer cell grafts.(Up to one year after transplantation)
- Overall survival of patients treated without stem cell manipulation or NK cell infusion due to off therapy criteria(Up to one year after transplantation)
- Incidence of relapse(Up to one year after transplantation)
