177Lu-DTPA-Omburtamab Radioimmunotherapy for Leptomeningeal Metastasis From Solid Tumors

Study Purpose

Adults with leptomeningeal metastasis from solid tumors will be treated with 177Lu-DTPA-omburtamab, which is a radioactive labelling of a murine monoclonal antibody targeting B7-H3.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

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.

Trial Details

Trial ID:

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.

NCT04315246
Phase

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.

Additional Details

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 five 5-week cycles of treatment doses of intracerebroventricular 177Lu-DTPA-omburtamab. Part 2 is a cohort-expansion phase in which patients will receive a treatment at the recommended dose determined in Part 1, until confirmed LM progression, unacceptable toxicity, or for maximum of 104 weeks, whichever comes first; however, the total number of cycles will be determined based upon data from Part 1 (e.g., the dosimetry data) to minimize the risk of radiation necrosis and decreased neurological function 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 until one year after first dose (Part 1) and 2 years after first dose (Part 2).
