MIBG With Dinutuximab
DFCI Protocol ID: 18-200
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 dose escalation 3+3 design to determine a recommended phase 2 pediatric dose. An expansion cohort of an additional 6 patients may then be enrolled.
