Summary

This Phase 1 study will assess the safety of a novel brain Bispecific T cell engager (BRiTE) in patients with newly diagnosed or recurrent World Health Organization (WHO) Grade 4 glioblastoma (GBM). Owing to its short half-life, the study drug, BRiTE, will be continuously infused intravenously (IV) for 4 days (96 hours) in a 28-day cycle. Given that BRiTE specifically exerts its effects on tumor cells expressing the Epidermal Growth Factor Receptor variant III (EGFRvIII) mutation, we will only enroll patients with EGFRvIII-positive tumors in this study. The primary objective is to evaluate the safety and tolerability of continually infused BRiTE in ndGBM and rGBM patients and determine the maximum tolerated dose (MTD) for continuously infused BRiTE.
