Everolimus (EVER) and tozasertib (TOZA) encapsulated in NP and targeted with dinutuximab β (DTX-β). DTX-β/EVER-TOZA@PEG-b-PLGA may exert cytotoxic and apoptotic effects in NB. The use of targeted nanocarriers in NB treatment may enhance cytotoxic and apoptotic responses specifically in the tumor region.

The incorporation of dinutuximab beta into a modified N7 induction regimen demonstrates a satisfactory EOI response rate and a manageable safety profile in children with HR-NB. These preliminary results support the feasibility of this chemoimmunotherapy approach and warrant further investigation in larger cohorts to confirm its efficacy in long-term survival outcomes.

The GADEKILL γδ T and NK cells were analyzed by flow cytometry for the expression of activating and inhibitory receptors and for cytotoxicity against NB, both with and without dinutuximab-β, at a 1:1 effector-to-target ratio...Finally, NB cell lysis positively correlated with B7H6 and BTN2A1, and B7H6-blocking experiments revealed a significant decrease in target cell lysis when cells highly expressing B7H6 were used as targets. Our study demonstrated the potential antineuroblastoma activity of the GADEKILL, supporting its therapeutic use, particularly in the context of relapsed/refractory R/R HR-NB with low GD2 expression.

Naxitamb+GM-CSF is a good option to consolidate post-relapse CR of HR-NB. The encouraging long-term outcome cannot be attributed solely to naxitamab+GM-CSF given post-protocol therapies.

All sensitivity unadjusted and adjusted comparisons supported the results of the base-case analysis. Dinutuximab beta significantly prolonged OS compared to historical control cohorts not treated with dB in both unadjusted and adjusted indirect comparisons.

Recent advances in immunotherapy have reshaped the treatment landscape, with anti-GD2 monoclonal antibodies such as dinutuximab and naxitamab demonstrating significant clinical benefit, especially when combined with granulocyte-macrophage colony-stimulating factor (GM-CSF)...This review synthesizes current evidence on immunotherapeutic strategies in neuroblastoma, highlighting resistance pathways, biomarker-driven approaches, and the evolving clinical trial landscape. Future directions emphasize personalized, biomarker-guided immunotherapy to improve efficacy, reduce toxicity, and establish durable, curative outcomes for children with neuroblastoma.
