Microbubble-enhanced transcranial focused ultrasound with temozolomide for patients with high-grade glioma (BT008NA): a multicentre, open-label, phase 1/2 trial.

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
backgroundBrain-infiltrating tumour cells from high-grade glioma remain shielded from drug treatments by the blood-brain barrier, leading to inevitable recurrence. Microbubble-enhanced transcranial focused ultrasound (MB-FUS) enables controlled blood-brain barrier opening (BBBO), permitting localised drug delivery. We aimed to assess safety and feasibility of MB-FUS plus standard-of-care chemotherapy for individuals with high-grade glioma.
methodsBT008NA was an open-label, single-arm, phase 1/2 trial conducted at five sites in the USA and Canada (part of the ReFOCUSED Consortium). Key eligibility criteria were participants with newly diagnosed high-grade glioma (glioblastoma as per WHO 2016 classification), aged 18-80 years, with normal organ function, a baseline Karnofsky Performance Status score of 70 or higher, who had received maximal safe resection and 6-week chemoradiotherapy and were to start standard-of-care monthly adjuvant temozolomide chemotherapy (150 mg/m
findingsBetween Oct 16, 2018, and March 9, 2022, we enrolled 34 participants, all evaluable for prespecified primary and secondary endpoints, with a mean age of 51·5 years (SD 13·0) and median follow-up 44·5 months (95% CI 34·9-57·3). By self-reporting, 18 (53%) participants were female and 16 (47%) male, 28 (82%) were White, and 34 (100%) were non-Hispanic. 176 adverse events were captured: 54 (31%) chemotherapy-related, 10 (6%) disease-related, 87 (49%) related to undergoing MB-FUS (40 [46%] grade 1, 46 [53%] grade 2, and one [1%] grade 3), and 25 (14%) unrelated. Two (1%) of the adverse events were grade 5 (disease-related deaths), three (2%) grade 4 (temozolomide-related haematological abnormalities), and eight (5%) grade 3 (three [2%] temozolomide-related, one [1%] MB-FUS-related, three [2%] disease-related, and one [1%] unrelated); these occurred across seven (21%) of 34 participants. No treatment-related deaths occurred during the trial. BBBO was visualised in all treatments. Median overall survival was 31·3 months (95% CI 21·1-not reached) and median progression-free survival was 13·5 months (9·9-26·9) with patient-specific disease courses found concordant with trajectories of MB-FUS-enriched plasma cell-free DNA.
interpretationMB-FUS plus temozolomide is a safe combinatorial therapeutic approach for individuals with high-grade glioma, with the potential to improve survival and enable non-invasive plasma biomarker-based disease surveillance (sono-liquid biopsy), warranting randomised controlled trials.
