Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

- - Patients must not have received cranial or spinal irradiation less than 3 weeks prior to first dose of 131I-omburtamab in this trial.
- - Patients must not have received systemic chemotherapy (corticosteroids not included) less than 3 weeks prior to enrollment in this trial.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

One 131I-omburtamab treatment cycle takes 4 weeks and includes a treatment dose, and an observation period and post-treatment evaluations. One 131I-omburtamab treatment cycle for Japan only takes 5 weeks and includes a dosimetry dose (2mCi) of 131I-omburtamab is administered during week 1 followed by blood/cerebral spinal fluid (CSF) samples and whole-body scintigraphy at predefined intervals during the following 48 hours after treatment.
- - A therapeutic dose (50mCi) of 131I-omburtamab is administered during week 1 (week 2 for Japan) followed by a 3-week observation period that includes a repeated MRI, CSF cytology, and safety monitoring.
- - A second treatment cycle of 131I-omburtamab is administered during week 5 (week 6 for Japan) if there is no objective disease progression week 5 after the first injection, and the participant is presenting without unexpected and clinical significant Grade 4 toxicity.
One treatment cycle of 131I-omburtamab consists of 1 dose at 50mCi at week 1. For Japan only one treatment cycle of 131I-omburtamab consists of 2 doses: 2mCi at week 1 and 50mCi at week 2. First cycle is initiated right after confirmation of eligibility at week 1. At week 5 (week 6 for Japan) the participant will be evaluated for safety and if eligible, receive a second cycle of 131I-omburtamab. Secondary efficacy endpoints will be evaluated at week 26 and primary efficacy endpoint will be evaluated at week 156.
Biological: - 131I-omburtamab
