This drug was developed by AbbVie. In May 2019 AbbVie stopped enrolment in all studies of Depatux-M after late-stage failure in newly diagnosed glioblastoma.[4]

In 2014, Orphan Drug Status was granted by the FDA for glioblastoma multiforme.[5] It is in phase II/III clinical trials for glioblastoma, in phase II clinical trials for non-small cell lung cancer, and in phase I clinical trials for the treatment of other solid tumors.[6] Phase I results were presented at ASCO in 2016.[6]
