The FDA Oncologic Drugs Advisory Committee (ODAC) unanimously decided on October 28 that there is insufficient evidence to support the claim that the pediatric oncology drug 131-I-omburtamab improves overall survival. A radiolabeled antibody, 131-I-omburtamab was created to treat central nervous system/leptomeningeal (CNS/LM) metastases in pediatric patients with neuroblastoma.
