• - Participation in other clinical trials utilizing other therapeutic investigational agents not included in this trial, within 30 days of the start of this trial and throughout the duration of this trial.

- Patients that have previously been treated with ixazomib, or participated in a study with ixazomib whether treated with ixazomib or not

PRIMARY OBJECTIVES:

• I. Measurement of tissue concentration of ixazomib (ixazomib citrate) in a glioblastoma after preoperative administration.

• II. Measurement of blood and plasma concentration of ixazomib during surgical sampling after preoperative administration.

SECONDARY OBJECTIVE:

• I. Assessment of the safety of ixazomib after single dose administration in glioblastoma patients undergoing surgery for tissue concentration assessment.

OUTLINE: Patients receive ixazomib orally (PO) 3 hours before surgery. After completion of study, patients are followed up for 30 days and then periodically thereafter.

Arms

Experimental: Ixazomib

Patients receive ixazomib PO 3 hours before surgery.
