An Open-Label, Multicenter, Phase I Study Evaluating the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Preliminary Clinical Activity of RO7428731 in Participants with Glioblastoma Expressing Mutant Epidermal Growth Factor Receptor Variant III


The purpose of this study is to find the highest dose of the investigational drug RO7428731 that can be given safely in people with glioblastoma that makes a protein called EGFRvIII.
