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

Technologies for the production of bispecific antibodies need to overcome two major challenges. The first one is correct heavy chain assembly, which was solved by knobs-into-holes technology or charge interactions in the CH3 domains. The second challenge is correct light chain assembly. This can be solved by engineering the Fab-arm interfaces or applying the immunoglobulin domain crossover approach. There are three different crossovers possible, namely Fab-arm, constant domain and variable domain crossovers. The CrossMabCH1-CL exchange does not lead to the formation of unexpected side products, whereas the CrossMabFab and the CrossMabVH-VL formats result in the formation of typical side products. Thus, CrossMabCH1-CL was initially favored for therapeutic antibody development. Here, we report a novel improved CrossMab design principle making use of site-specific positional exchanges of charged amino acid pairs in the constant domain of these CrossMabs to enable the correct light chain assembly in the CrossMabVH-VL and improvements for the CrossMabFab design.
