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.

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.

The disease, disorder, syndrome, illness, or injury that is being studied.
Part 1 is a dose-escalation phase with a 3+3 sequential-group design in which patients will receive a dosimetry dose followed by maximum of two 5-week cycles of treatment doses of intracerebroventricular 177Lu-DTPA-omburtamab. Part 2 is a cohort-expansion phase in which patients will receive a maximum of five 5-week cycles of intracerebroventricular 177Lu-DTPA-omburtamab at the recommended dose determined in Part 1. End of treatment will take place within 5 weeks after the last cycle and thereafter the patients will be enter the follow-up period. The patients will be followed for up to 2 years after last dose.
Intracerebroventricular administration of 177Lu-DTPA-omburtamab for up to two cycles (Part 1) and up to five cycles (Part 2).
Drug: - 177Lu-DTPA-omburtamab
Biological, radiolabeled DPTA-omburtamab
