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

Monoclonal antibodies (mAbs) with pan-ebolavirus cross-reactivity are highly desirable, but development of such mAbs is limited by a lack of a molecular understanding of cross-reactive epitopes. The antibody ADI-15878 was previously identified from a human survivor of Ebola virus Makona variant (EBOV/Mak) infection. This mAb demonstrated potent neutralizing activity against all known ebolaviruses and provided protection in rodent and ferret models against three ebolavirus species. Here, we describe the unliganded crystal structure of ADI-15878 as well as the cryo-EM structures of ADI-15878 in complex with the EBOV/Mak and Bundibugyo virus (BDBV) glycoproteins (GPs). ADI-15878 binds through an induced-fit mechanism by targeting highly conserved residues in the internal fusion loop (IFL), bridging across GP protomers via the heptad repeat 1 (HR1) region. Our structures provide a more complete description of the ebolavirus immunogenic landscape, as well as a molecular basis for how rare but potent antibodies target conserved filoviral fusion machinery.
