Studies have shown that the anti-GD2 human-mouse chimeric monoclonal antibody dinutuximab has contributed significantly to the improvement of treatment for children with high-risk neuroblastoma and has become a mainstay in treating high risk neuroblastoma in children as part of up-front therapy and relapsed/refractory therapy. The administration of dinutuximab requires a significant amount of time and resources to complete the 10-20 hour standard infusion time for 4 days in the inpatient setting. During its early development, a phase I study profiling the clinical efficacy and tolerability of dinutuximab infusions in children successfully infused dinutuximab at various rates including over 1 hour at different dose levels. In the adult setting, dinutuximab has been tolerated over substantially shorter infusion times (less than 2 hours). Additionally, another anti-GD2 murine monoclonal antibody naxitamab, which has a similar toxicity profile to dinutuximab, is FDA approved for administration over 90 minutes and is successfully administered in outpatient setting. Given this reassuring data we aim to evaluate the feasibility of the rapid administration of dinutuximab over four hours or less in our patient population of children with high-risk neuroblastoma. The pharmacokinetics, toxicity profile and supportive care requirements will be analyzed and described in order to determine if rapid infusion of dinutuximab can be successfully tolerated over four hours or less which would allow for administration of this agent in the outpatient setting. Should this trial prove to be successful, it would serve to decrease the hospital burden in a positive way by allowing for administration of this immunotherapy agent in the outpatient setting and patients may prefer shorter infusion duration. Furthermore, it could lessen overall costs and inpatient admissions for patients.
