this study s primary objective was evaluation of the progression free survival rate at 6 months pfs 6 in patients with newly diagnosed glioblastoma without o 6 methylguanine dna methyltransferase mgmt promoter hypermethylation postsurgically treated with enzastaurin before and concomitantly with radiation therapy followed by enzastaurin maintenance therapy pfs 6 of at least 55 was set to be relevant compared with the data of the eortc 26981 22981 ncic ce 3 trial adult patients with a life expectancy of at least 12 weeks who were newly diagnosed with a histologically proven supratentorial glioblastoma without mgmt promoter hypermethylation were eligible patients were treated with enzastaurin prior to concomitantly with and after standard partial brain radiotherapy here we report on a multicenter open label uncontrolled phase ii study of patients with newly diagnosed glioblastoma without mgmt promoter hypermethylation treated with enzastaurin and radiation therapy within 4 study periods pfs 6 was 53 6 95 confidence interval ci 39 8 65 6 the median overall survival was 15 0 months 95 ci 11 9 17 9 for all patients 3 9 months 95 ci 0 8 9 0 for patients with biopsy 15 4 months 95 ci 10 1 17 9 for patients with partial resection and 18 9 months 95 ci 13 9 28 5 for patients with complete resection the safety profile in this study was as expected from previous trials and the therapy was well tolerated pfs 6 missed the primary planned outcome of 55 the secondary exploratory analysis according to resection status of the different subgroups of patients with biopsies partial resection and complete resection demonstrates the strong prognostic influence of resection on overall survival.
