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. The main study for all countries except China is closed. The sub-study of ABT-414 in participants with newly diagnosed EGFR-amplified GBM who have mild or moderate hepatic impairment is open to enrollment.
