For participants with ongoing Grade 3 toxicity a second doing cycle will take place according to the discretion of the investigator.\n\nParticipants can be treated in an outpatient setting or may be admitted as inpatients for both the dosimetry and the therapeutic injections.\n\nParticipants completing at least one treatment period will first enter a follow-up period through week 26 and thereafter the long-term follow-up where patients will be evaluated for up to 3 years post-131I-omburtamab treatment where after the trial is ended\n\nParticipants will be monitored for adverse events during and after 131I-omburtamab injection and will have pre- and post-treatment clinical assessments including neurologic examination, hematology and serum chemistry, blood and CSF cultures, endocrinology assessments, CSF analysis, and, pre- and post 131I-omburtamab performance testing. Performance testing will be performed at trial baseline, at week 26 and every 6 months during trial period.\n\nIn case the patient has a subsequent relapse in the CNS/LM after 131I-omburtamab therapy during the follow-up period, re-treatment to target minimal residual disease can be considered and allowed.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT'], 'maximumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patients must have a histologically confirmed diagnosis of neuroblastoma with relapse in the central nervous system or in the meninges (leptomeningeal).\n* Patients must be between the ages of birth and 18 years at the time of screening.\n* Patients must have a life expectancy of at least 3 months.\n\nExclusion Criteria:\n\n* Patients with primary neuroblastoma in central nervous system.\n* Patients must not have an uncontrolled life-threatening infection.\n* Patients must not have received cranial or spinal irradiation less than 3 weeks prior to first dose of 131I-omburtamab in this trial.\n* Patients must not have received systemic chemotherapy (corticosteroids not included) less than 3 weeks prior to enrollment in this trial.\n* Patients must not have severe major non-hematologic organ toxicity; specifically, any renal, cardiac, hepatic, pulmonary, and gastrointestinal system toxicity must fall below Grade 3 prior to enrollment in this trial.
