RTOG Foundation Study 3508/AbbVie 414_M13-813

Status Date:  May 15, 2019  | Status:  Closed to Accrual

A Study of ABT-414 in Participants With Newly Diagnosed Glioblastoma (GBM) With Epidermal Growth Factor Receptor (EGFR) Amplification (Intellance1)

Principal Investigator

Andrew Lassman, MD

Primary Objective

This study seeks to determine whether the addition of ABT-414 to concomitant radiotherapy and temozolomide (TMZ) followed by combination of ABT-414 with adjuvant TMZ prolongs overall survival (OS) among participants with newly diagnosed glioblastoma (GBM) with epidermal growth factor receptor (EGFR) amplification. In addition, there is a Phase 1, open-label, multicenter sub-study to assess the pharmacokinetics, safety and tolerability of ABT-414 in participants with newly diagnosed EGFR-amplified GBM who have mild or moderate hepatic impairment.

Patient Population

Histologically confirmed de novo Grade IV glioma (glioblastoma, gliosarcoma or other subvariants) confirmed by central pathology tissue screening and EGFR amplification in tumor tissue confirmed by central assessment.
