Improved GD2 Ab for neuroblastoma (SJ-17-0017)

St. Jude Reference #SJ-17-0017


We are offering an improved, genetically modified version of Unituxan (dinutuximab), an approved monoclonal antibody (mAb) targeting the disialoganglioside GD2.  This improved antibody therapeutic has a significantly better tolerance profile and is known as hu14.18K322A.

Neuroblastoma is the most common extracranial solid tumor in childhood. Hu14.18K322A used in standard therapy resulted in improved survival rates in patients with high-risk disease. Patients with high risk neuroblastoma who had at least a partial response to standard induction chemotherapy and were randomly assigned to receive the antibodies combined with cytokines and isotretinoin in the maintenance phase had longer event-free and overall survival compared with those who received isotretinoin alone. Similarly, in an update of the Cooperative German Neuroblastoma Trials, patients who received hu14.18K322A had better long-term outcomes.
