Study Summary

A Phase 2 study investigating the addition of cRIT 131I-omburtamab to irinotecan, temozolomide, and bevacizumab for patients with recurrent medulloblastoma. A feasibility cohort is included to assess the feasibility of incorporating cRIT 131I-omburtamab for patients with recurrent ependymoma. Direct intraventricular delivery of radiolabeled tumor-specific antibodies may aid in both the detection and treatment of recurrent disease for these highly specific pediatric patients with recurrent tumors.

Primary Outcome

Using the Kaplan Meier method, estimate of event-free survival (EFS) of patients with relapsed medulloblastoma treated with the study regimen. EFS is defined as the interval of time between enrollment on the study and the minimum date of documentation of progressive disease, death due to any cause, subsequent malignancy or date of last follow-up.
