Clinical Trial Summary

This is a single-arm clinical trial to evaluate the efficacy and safety of quadruple immunotherapy with natural killer (NK) cells, anti-GD2 antibody, cytokines (interleukin-2 (IL-2) and granulocyte-macrophage colony stimulating factor (GM-CSF)) and retinoid X receptor gamma (RXRg) agonist spironolactone for paediatric patients with relapsed or refractory neuroblastoma.


Clinical Trial Description

Included patients will receive intravenous infusion of donor NK cells on day 0, and anti-GD2 antibody (dinutuximab) on day -6 to day -2. IL-2 will be given subcutaneously on day -1, day +1, day +3, day +5, day +7, and day +9. Subcutaneous injection of GM-CSF will be started on day 0, given daily till neutrophil count >1000/mm3. Spironolactone will be started orally on day -1, given three times daily till cessation of GM-CSF. Alternative anti-GD2 antibody (Naxitamab) can be used instead of dinutuximab, to be given on day -5, day -3, day +1 and day +3. ;
