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

aimsTreatment with enzalutamide in prostate cancer is challenging due to its high potential for drug-drug interactions, particularly in the typically older population of patients with frequent comorbidities treated with multiple drugs, such as anticoagulants. While low molecular weight-heparin can be safely combined with enzalutamide, the safety of combining enzalutamide with more convenient oral anticoagulants remains uncertain. The objective of this study was to assess whether a drug-drug interaction exists between enzalutamide and edoxaban.

methodsA prospective, multicentre, two-arm parallel study was performed in men with prostate cancer who are treated with edoxaban, with and without enzalutamide. Plasma concentrations of edoxaban were measured at steady state. Pharmacokinetic (PK) parameters were calculated using non-compartmental analysis. Geometric mean ratios (GMR) of the area under the plasma concentration time curve over one dosing interval (AUC

resultsSixteen patients with prostate cancer using edoxaban (eight patients with enzalutamide and eight patients without enzalutamide) were enrolled. The exposure of edoxaban was similar between patients treated with or without enzalutamide, however the 90% CI fell outside of the 0.8-1.25 range (AUC

conclusionsThe average exposure of edoxaban was not affected by enzalutamide. However, bioequivalence could not be established due to the broader than anticipated CI. Despite this, the larger variability in edoxaban exposure is not expected to be clinically relevant, supporting the safe co-administration of both drugs.
