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

purposeThe aim of this study was to evaluate the in vitro and in vivo characteristics of [(89)Zr]JRF/AβN/25, a radiolabeled monoclonal antibody directed against amyloid-β (Aβ). PROCEDURES: JRF/AβN/25 was labeled with (89)Zr following modification with desferal. The affinity of the tracer for Aβ1-40 was determined in a saturation binding assay. In vitro stability was evaluated, and in vivo plasma stability and biodistribution of [(89)Zr]Df-Bz-JRF/AβN/25 were determined in wild-type mice. To evaluate whether the antibody can cross the blood-brain barrier, brain uptake in wild-type mice was additionally assessed by ex vivo autoradiography.

results[(89)Zr]Df-Bz-JRF/AβN/25 was obtained in an average radiochemical yield of 50 % and a radiochemical purity of >97 %. A saturation binding assay demonstrated specific binding of [(89)Zr]Df-Bz-JRF/AβN/25 to Aβ1-40 with nanomolar affinity. The tracer was stable in buffer and proved to be stable in vivo with >92 % intact monoclonal antibody (mAb) remaining in the plasma at 48 h post injection. A biodistribution study showed a slow blood clearance with no significant accumulation of activity in any of the organs. Furthermore, [(89)Zr]Df-Bz-JRF/AβN/25 demonstrated modest brain penetration, which slowly decreased in time. This cerebral uptake was confirmed by ex vivo autoradiography.

conclusions[(89)Zr]Df-Bz-JRF/AβN/25 binds with high affinity to Aβ1-40. The tracer displays an acceptable in vivo stability and is able to cross the blood-brain barrier. [(89)Zr]Df-Bz-JRF/AβN/25 might therefore be a potential candidate for in vivo imaging of Aβ deposition in the brain.
