Despite EBRT, LRR remains a contributor to treatment failure in HR-NBL with approximately half of LRRs including a component of marginal failure. Future prospective studies are needed to explore whether radiation fields and doses should be defined based on molecular features such as MYCN amplification, and/or response to chemotherapy.

We assessed the avidity and selectivity of our GD2-B7-H3 targeting bispecific antibodies (INV34-6, INV33-2, and INV36-6) towards GD2 + /hB7-H3 - B78 cells relative to GD2 + /hB7-H3 + B78 cells using flow cytometry and competition binding assays, comparing results an anti-GD2 antibody (dinutuximab, DINU). The bispecific antibodies, DINU, and a non-targeted bispecific control (bsAb CTRL) were conjugated with deferoxamine for radiolabeling with Zr-89 (t 1/2 = 78.4 h)...This approach should address the severe toxicities associated with GD2-targeting therapies by reducing off-tumor GD2 binding in nerves. Continued improvements in bispecific antibody technologies will continue to transform the therapeutic biologics landscape.

These promising results highlight the potential to enhance immunotherapy efficacy against high-risk neuroblastoma through improved neutrophil cytotoxicity by combining IgA therapy with CD47 blockade.

Moreover, ex vivo culture with IL-7+IL-15+IL-21 could favor CAR-T products with a longer persistence in the host. Our strategy may complement the current use of Dinutuximab in treating NB through its combination with a targeted CAR-T cell approach.

The N-803 combined with dinutuximab and exPBNK cells significantly extended the survival of NB xenografts (Chu/Cairo, et al, JITC...C021 was generated by modifying C134 to express human IL21 gene... Our data demonstrated IL15 or IL21 based novel cytokine therapy (N-803 or C021) significantly enhanced the anti-tumor efficacy of ROR1 CAR NK targeting NB in vitro and in vivo

We observed excellent outcomes in 99 pts treated with proton radiotherapy for HR-NBL from 2010 through 2021, with 81% of patients alive and 92% free of LR. Our data suggest that LR is rare after GTR and 21.6 Gy, and uncommon among pts with STR treated with 36 Gy. A small number of pts received 21.6 Gy after STR, however, this experience suggests that a subset of pts with RD may require RT dose > 21.6 Gy. Further work is required to further characterize individual management of PS in pts with HR-NBL with regard to extent of RD and biologic disease features.

The EOI response of PR or better in the evaluable cohort was 96%. Dinutuximab was well tolerated with all Induction cycles, demonstrated an encouraging EOI response rate, and should be evaluated in a randomized study.

Results found that dinutuximab β is not a cost-effective treatment option for children with high-risk NB unless its price is significantly reduced.

Patients with relapsed neuroblastoma are often treated with immunotherapy such as the anti-GD2 antibody, dinutuximab, in combination with chemotherapy...The mechanism of ST8SIA1 suppression by YAP is independent of PRRX1 expression, a mesenchymal master transcription factor, suggesting YAP may be the downstream effector of mesenchymal GD2 resistance. These results therefore identify YAP as a therapeutic target to augment GD2 immunotherapy responses in patients with neuroblastoma.

IgA3.0 ch14.18 is a promising new therapy for neuroblastoma, showing (1) increased half-life compared to natural IgA antibodies, (2) increased protein stability enabling effortless production and purification, (3) potent CD89-mediated tumor killing in vitro by healthy subjects and patients with neuroblastoma and (4) antitumor efficacy in long-term mouse neuroblastoma models.

Daily average of IV morphine milligram equivalents (MME) and ketamine intake was calculated for each cycle of dinutuximab. Preliminary findings suggest an acceptable adverse effect profile with ketamine use as an adjunctive opioid therapy to relieve pain in pediatric patients receiving dinutuximab infusions.

While immunotherapy for pediatric cancer has made great strides in recent decades, including the FDA approval of agents such as dinutuximab and tisgenlecleucel, these successes have rarely impacted children with pediatric central nervous system (CNS) tumors...Combinatorial strategies and future directions will be addressed. Through internationally collaborative efforts and consortia, we aim to direct this promising field of immuno-oncology to the next frontier of successful application against pediatric CNS tumors.
