To summarise, the initial characterisations demonstrated positive SSTR2 expression in all three in vivo NB-models, validated the p53 stabilising properties and wt-p53 specificity of VIP116 in vivo and identified IMR-32 as the most suitable xenograft model for subsequent [177Lu]Lu-DOTATATE studies. The gene discussed is SSTR2; the disease is neuroblastoma.
