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

Capitalizing on their extraordinary specificity, monoclonal antibodies (mAbs) have become one of the most reengineered classes of biological molecules. A major goal in many of these engineering efforts is to add new functionality to the parental mAb, including the addition of cytotoxins and imaging agents for medical applications. Herein, we present a unique peptide-binding site within the central cavity of the fragment antigen binding framework region of the chimeric, anti-epidermal growth factor receptor mAb cetuximab. We demonstrate through diffraction methods, biophysical studies, and sequence analysis that this peptide, a meditope, has moderate affinity for the Fab, is specific to cetuximab (i.e., does not bind to human IgGs), and has no significant effect on antigen binding. We further demonstrate by diffraction studies and biophysical methods that the meditope binding site can be grafted onto the anti-human epidermal growth factor receptor 2 mAb trastuzumab, and that the antigen binding affinity of the grafted trastuzumab is indistinguishable from the parental mAb. Finally, we demonstrate a bivalent meditope variant binds specifically and stably to antigen-bearing cells only in the presence of the meditope-enabled mAbs. Collectively, this finding and the subsequent characterization and engineering efforts indicate that this unique interface could serve as a noncovalent "linker" for any meditope-enabled mAb with applications in multiple mAb-based technologies including diagnostics, imaging, and therapeutic delivery.
