Trial Outcomes & Findings for Phase 0 Analysis of Ixazomib (MLN9708) in Patients With Glioblastoma (NCT NCT02630030)

NCT ID: NCT02630030

Last Updated: 2021-03-26

Results Overview

The relationship between patient's demographic, tumor and drug concentration results will be assessed with Pearson's correlation coefficient and tested with Wald's test. In addition, the mean and standard error of the concentrations will be estimated using a random-effects model to account for the within-patient correlation of the tumor biopsy samples. Given the limited number of observations, a relatively simple covariance matrix (e.g. compound symmetry) will be assumed.

PRIMARY outcome

Timeframe: At time of surgery, approximately 3 hours

Population: Each participant's sample was analyzed separately. For participant 3, 3 samples were collected and analyzed in order to account for intratumor variability

The relationship between patient's demographic, tumor and drug concentration results will be assessed with Pearson's correlation coefficient and tested with Wald's test. In addition, the mean and standard error of the concentrations will be estimated using a random-effects model to account for the within-patient correlation of the tumor biopsy samples. Given the limited number of observations, a relatively simple covariance matrix (e.g. compound symmetry) will be assumed.

PRIMARY outcome

Timeframe: At the time of surgery, approximately 3 hours

Safety was assessed with routine postoperative laboratory, vital sign, neurologic exam, and imaging studies through the day of surgery to staple or suture removal. This data was collected and any adverse events graded and their relationship to ixazomib administration determined.

Timeframe: Up to 30 days

The National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (NCI CTCAE) was used to stratify any adverse patient response to ixazomib. There were no clinically relevant adverse events as a result of ixazomib administration.
