1 · What the graph read from it

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.

2 · The registry

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

ABL1 and ABL2 are putative drivers of medulloblastoma leptomeningeal dissemination. ABL1/ABL2 inhibitors, nilotinib and asciminib, are P-glycoprotein substrates. The purpose of this work is to elucidate P-glycoprotein expression in the brain/brain tumors and to determine if P-glycoprotein inhibition increases plasma and brain concentrations and medulloblastoma cytotoxicity of nilotinib and asciminib. ABCB1 (P-glycoprotein) mRNA expression was analyzed from multiple datasets of brain and brain tumor specimens. Cytotoxicity assays of medulloblastoma cells were conducted. In a mouse model, the pharmacokinetics of asciminib and nilotinib, with and without tariquidar, were determined using LC/MS. ABCB1 mRNA expression varied by brain region and was significantly lower in the cerebellum ( P  < 0.05). There was a bimodal increase in brain ABCB1 expression at ages 0-3 and 21-23 ( P  < 0.05). ABCB1 expression in pediatric brain tumors was similar to normal brain. The addition of tariquidar significantly reduced medulloblastoma cell viability compared to asciminib alone ( P  < 0.01). Tariquidar increased asciminib plasma and brain concentrations at 24 h ( P  = 0.0005 and P  = 0.0002, respectively) and nilotinib brain concentrations at 3 h ( P  = 0.0009). Tariquidar increased the area under the curve (AUC) brain : plasma ratio of asciminib from 0.33 to 10.16% and of nilotinib from 1.16 to 9.61%. Tariquidar prolonged the plasma half-life of asciminib from 2.21 to 10.49 h and nilotinib from 7.63 to 14.64 h. P-glycoprotein inhibition increased the brain concentrations, AUC, and half-life of asciminib and nilotinib and increased cytotoxicity in medulloblastoma cells.
