Another attempt to produce an effective therapy for glioblastoma multiforme (GBM), an aggressive brain cancer, has failed. This time it was a study testing the checkpoint antibody Opdivo (nivolumab) plus radiation in patients with newly diagnosed disease. The Phase 3 trial, known as CheckMate-498, did not meet its primary endpoint of overall survival at final analysis, according to the sponsor Bristol-Myers Squibb Co.
