A Post-Authorisation Safety Study Patient Registry of Patients With Neuroblastoma Being Treated With Dinutuximab Beta

Rationale and Background:

Neuroblastoma, is the most common extra-cranial solid tumour in children. Most patients with neuroblastoma are diagnosed under the age of 5 years and most present with metastatic disease and/or high-risk features. Despite the introduction of novel treatment strategies, including high-dose chemotherapy followed by autologous stem cell transplantation (ASCT), the outcome of these patients remains poor.

Dinutuximab beta is a chimeric monoclonal immunoglobulin G 1 (IgG1) antibody that is specifically directed against the carbohydrate moiety of disialoganglioside antigen (GD2), which is overexpressed on neuroblastoma cells. By binding to neuroblastoma cells, dinutuximab beta can induce both complement dependent cytotoxicity (CDC) and antibody dependent cell-mediated cytotoxicity (ADCC).

The efficacy of dinutuximab beta has been evaluated in a randomised controlled trial comparing the administration of dinutuximab beta with or without interleukin 2 (IL-2) in the first-line treatment of patients with high-risk neuroblastoma and in two singlearm studies in the relapsed/refractory setting. The efficacy and safety of dinutuximab beta will further be evaluated in this registry that will provide information on survival, pain severity and incidence of neurotoxicity, visual impairment, capillary leak syndrome, cardiovascular events, hypersensitivity reactions and long-term safety.

Study Design:

This is a non-interventional, multi-national, observational, prospective patient registry of patients with high-risk neuroblastoma being treated with the monoclonal antibody dinutuximab beta. The efficacy and safety of dinutuximab beta will further be evaluated in this registry that will provide information on survival, pain severity and incidence of neurotoxicity, visual impairment, capillary leak syndrome, cardiovascular events, hypersensitivity reactions and long-term safety.

Research Questions and Objectives:

Primary objectives:

* To assess pain severity and use of analgesics during the period of first dose of dinutuximab beta to end of last 35 day course of the 5th cycle of treatment * To assess the incidence of neurotoxicity, visual impairment, capillary leak syndrome, cardiovascular events and hypersensitivity reactions * To assess the long term safety profile
