What this trial studies

This clinical trial evaluates the safety and efficacy of a quadruple immunotherapy approach for pediatric patients with relapsed or refractory neuroblastoma. Participants will receive a combination of natural killer (NK) cells, anti-GD2 antibodies, cytokines (IL-2 and GM-CSF), and a retinoid X receptor gamma agonist, spironolactone. The treatment regimen includes intravenous and subcutaneous infusions over a specified timeline to enhance the immune response against the cancer. The study aims to determine if this innovative combination can improve outcomes for children facing this challenging condition.

Who should consider this trial

Good fit: Ideal candidates for this study are pediatric patients diagnosed with relapsed or refractory neuroblastoma who have an appropriate NK-cell donor available.

Not a fit: Patients with terminal malignancies and a life expectancy of less than one month are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for children with relapsed neuroblastoma, potentially improving survival rates.

How similar studies have performed: While the approach of using quadruple immunotherapy is innovative, similar studies involving immunotherapy for neuroblastoma have shown promising results, indicating potential for success.
