Full TitlePhase 2 Study of Intraventricular Omburtamab-based Radioimmunotherapy for Pediatric Patients with Recurrent Medulloblastoma and Ependymoma (PBTC 058) (CIRB)
In this study, researchers are evaluating the use of a radioimmunotherapy called 131I-omburtamab in children and adolescents with medulloblastoma and ependymoma (types of brain tumors) that have come back despite treatment. 131I-omburtamab binds to cancer cells in the body and releases radiation, which kills the cells. Early studies have also shown that 131I-omburtamab might strengthen the anticancer effects of chemotherapy.
Patients with medulloblastoma will receive intravenous (by vein) chemotherapy before and after 131I-omburtamab. Patients with ependymoma will only receive 131I-omburtamab. 131I-omburtamab is given directly into the brain through a catheter (thin tube) that is placed during surgery.
To be eligible for this study, patients must meet several criteria, including but not limited to the following:
- Patients with medulloblastoma must have cancer that came back or continued to grow despite prior therapy which did not include bevacizumab, irinotecan, and temozolomide (the chemotherapy used in this study).
- Patients with ependymoma must have cancer that came back or continued to grow despite prior therapy and have the B7H3 marker on their tumors.
- All patients must recover from the serious side effects of prior treatments before receiving the study therapy.
- Patients must be able to walk and do routine activities for more than half of their normal waking hours.
- This study is for patients under age 22.
