EORTC 1709/CCTG CE.8: A phase III trial of marizomib in combination with standard temozolomide-based radiochemotherapy versus standard temozolomide-based radiochemotherapy alone in patients with newly diagnosed glioblastoma.
Bibliographic record
Abstract
TPS2072 Background: The standard treatment for patients with newly diagnosed glioblastoma comprises maximum safe surgery, radiotherapy (RT), and concomitant and up to six cycles of maintenance temozolomide (TMZ) chemotherapy (TMZ/RT→TMZ). Despite this intense therapy, the prognosis remains poor and there is an urgent need to develop new therapeutic options. Marizomib is a novel, irreversible and brain-penetrant pan-proteasome inhibitor. Following its successful assessment in phase I trials in patients with newly diagnosed as well as recurrent glioblastoma, marizomib is now being investigated in a phase III trial. Methods: EORTC 1709/CCTG CE.8 is a multicenter, randomized, controlled, open label phase III superiority trial. Eligibility criteria include histologically confirmed newly diagnosed glioblastoma and a performance status ≥70. Approximately a total of 750 patients will be enrolled and randomized 1:1. Stratification factors include institution, age, Karnofsky performance status and extent of surgery. The primary objective of this study is to compare overall survival in patients receiving marizomib in addition to standard of care (TMZ/RT→TMZ) with patients receiving standard treatment only. The testing strategy specifies the determination of this objective in both the intent-to-treat population and the subgroup of patients with tumors harboring an unmethylated MGMT promoter. Secondary endpoints include progression-free survival, safety, neurocognitive function and quality of life. The study is accompanied by a translational research program. The study will be opened at 50 EORTC sites in Europe and done as an intergroup collaboration with the Canadian Cancer Trials Group (CCTG) with 25 sites in Canada and additional sites in the US. Patient enrolment started in June 2018 and as of January 29, 2019, a total of 85 patients have been randomized. An update on the enrolment status will be provided at the ASCO conference. Clinical trial information: NCT03345095.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
