Safety and Feasibility of First-line Avutometinib and Defactinib in Patients With Newly Diagnosed High-grade Gliomas

This clinical trial is designed with two treatment stages: Stage 1: one cycle of study drug treatment prior to initiation of first-line standard radiation in all study participants. Stage 2: two additional cycles of study drug treatment (8 weeks total) concomitantly with standard of care radiation (\~6 weeks) for participants with pathology-confirmed MGMT (enzyme O-6-methylguanine-DNA methyltransferase) unmethylated GBM only. The co-primary endpoints of the study are 1) feasibility of completing Stage 1 of treatment prior to radiation in all study participants and starting radiation within 6 weeks, and 2) safety of study drug across both treatment parts. The investigators will additionally evaluate the radiographic response rate after the first cycle of drug in all patients based upon RANO 2.0 (Response Assessment in Neuro-Oncology) criteria as well as safety of study drug in all patients (secondary endpoints). Exploratory endpoints will include characterization of ERK (extracellular signal-regulated kinase) and FAK (Focal adhesion kinase) dependence in pre-treatment tissue (by immunohistochemistry and/or 'omics) and correlation of expression and co-mutations with response and survival. A total of up to 22 evaluable patients can be enrolled in this study. Evaluable patients are those who have received at least one dose of study drug treatment. Patients who do not start drug will be replaced, up to a total of 28 patients.
