VAL-083 is effective in patients with newly-diagnosed MGMT-unmethylated glioblastoma: report of phase II study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeUnmethylated MGMT is a validated biomarker for temozolomide (TMZ) resistance and poor prognosis in glioblastoma. VAL-083 (dianhydrogalactitol; DAG) is a DNA-targeting agent that forms interstrand crosslinks at O6/N7-guanine, inducing double-strand breaks and cell death independently of MGMT-mediated DNA repair. This study aimed to evaluate whether first-line VAL-083 combined with radiotherapy improves efficacy compared to standard-of-care TMZ plus radiotherapy in newly diagnosed MGMT-unmethylated GBM patients.
methodsVAL-083 was administered intravenously on days 1-3 of a 21-day cycle, starting on day 1 of radiotherapy, with a second 3-day cycle on days 22-24 of radiotherapy. After completing the 6-week radiotherapy regimen, patients began adjuvant maintenance therapy with VAL-083 alone, administered IV at the same dose and regimen (Cycles 3-10), for up to 8 maintenance cycles.
resultsAt the censor date, the median overall survival (OS) across all patients from the start of VAL-083 treatment was 19.2 months across all dose levels. Survival probabilities from VAL-083 were 93.0%, 68.7%, 51.2%, and 28.4% at 6, 12, 18, and 24 months, respectively. For patients receiving 30 mg/m
