About this trial
The goal of this clinical trial is to assess safety and efficacy of systemic injection of allogenic NK cells in patients with refractory/recurrent high-risk neuroblastoma.
Is the injection of allogenic nk cells safe in patients with R/R high-risk neuroblastoma? Is the injection of allogenic nk cells effective in patients with R/R high-risk neuroblastoma? We will compare the NK cell administration group with a control group that receives conventional treatment to determine whether the intervention is safe and effective
Eligibility criteria
Qualifiers
High-risk neuroblastoma that is resistant to standard induction therapy based on COG (Children's Oncology Group) criteria (according to INRG criteria and having received at least 4 cycles of multi-drug induction chemotherapy, and not responding to conventional treatments).
Evidence of relapse or progression of neuroblastoma after autologous peripheral blood stem cell transplantation or aggressive therapy.
A minimum life expectancy of 6 months.
Patients must have a pathological diagnosis of neuroblastoma and/or confirmation of tumor cells in the bone marrow with increased urinary catecholamines.
Disqualifiers
Insufficient bone marrow function: Platelet count > 50,000/µL, independent of transfusion (no platelet transfusion within one week). Absolute neutrophil count (ANC) maximum of 500 per microliter. Hemoglobin > 10 grams per deciliter.
Insufficient liver function: Plasma bilirubin level more than 1.5 times the upper limit of normal (ULN). SGPT (ALT) at least three times the upper limit of normal (a level of 45 units per liter is considered the upper limit of normal).
Insufficient kidney function: Creatinine clearance or estimated radioisotope GFR < 70 ml/min/1.73m². Plasma creatinine level more than 1.5 times the upper limit of normal based on age/gender.
Insufficient central nervous system function if seizures are present, entry into the study is not possible and if seizures are not well controlled with anticonvulsant drugs.
