Collectively, these findings delineate an NRG3-ERBB4 axis-centered tumor-immune crosstalk that operates across pretreatment, chemotherapy, and CI, uncovering a previously unrecognized mechanism underlying naxitamab-mediated immune activation. Our results also support ERBB4 as a promising predictive biomarker and therapeutic target to optimize CI strategies for high-risk NB.
Mild adverse events occurred during the combined immunotherapy, including transient hypotension managed with intravenous fluids and abdominal and leg pain that improved with analgesics. In conclusion, our case showed that combination therapy with naxitamab and lorlatinib may improve long-term outcomes and reduce chemotherapy-related toxicity.

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.
