A Phase I Study of 131I-MIBG With Dinutuximab +/- Vorinostat for Relapsed/Refractory Neuroblastoma

New Approaches to Neuroblastoma Therapy Consortium·interventional·Posted Nov 6, 2017·Updated Apr 16, 2025

In Brief

A Phase 1 clinical trial evaluating 131I-MIBG, Dinutuximab, and 3 other interventions for Neuroblastoma. Completed, enrolled 45 participants across 12 sites.

Detailed Summary

131I-Metaiodobenzylguanidine (131I-MIBG) is one of the most effective therapies utilized for neuroblastoma patients with refractory or relapsed disease. In this pediatric phase 1 trial, 131I-MIBG will be given in combination with dinutuximab, a chimeric 14.18 monoclonal antibody. This study will utilize a traditional Phase I rolling 6 dose escalation design to determine a recommended phase 2 pediatric dose. An expansion cohort of an additional 6 patients will then be enrolled. If tolerable, vorinostat will then be added to the third dose level. A 6 patient expansion cohort may then be enrolled.
