Trial Outcomes & Findings for BrUOG 263: Prostate Specific Membrane Antigen (PSMA) Glioblastoma Multiforme (GBM) (NCT NCT01856933)

NCT ID: NCT01856933

Last Updated: 2021-11-23

Results Overview

(PD): A \>25% increase in tumor area (product of two diameters) OR appearance of a new lesion/site, OR clear clinical worsening or failure to return for evaluation due to death or deteriorating condition (unless clearly unrelated to this cancer).
