Impact of Maleimide Disubstitution on Chemical and Biological Characteristics of HER2 Antibody-Drug Conjugates.

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.
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
Antibody-drug conjugates (ADCs) are the spearhead of targeted therapies. According to the technology used, the conjugation of a cytotoxic drug to an antibody can produce suboptimal heterogeneous species, impacting the overall efficacy. Herein, we describe the synthesis of HER2-targeting ADCs with three disulfide rebridging heads, allowing homogeneous and site-specific bioconjugation: dibromomaleimide (DBM), dithiomaleimide (DTM), and hybrid thio-bromomaleimide (TBM) chemical bricks to combine the properties of both previously used heads. The primary purpose of this study was to compare the reactivity of these three chemical bricks in the bioconjugation process. Then, the resulting ADCs were evaluated in terms of physicochemical stability, binding, and biological activity. We have demonstrated that the higher percentage of a drug-to-antibody ratio of 4 was obtained with TBM. Additionally, the reaction time was drastically reduced with TBM in comparison to DTM. The three ADCs showed good binding to HER2 and in vitro cytotoxicity, which validate the TBM structure as an attractive alternative scaffold for rebridging bioconjugation.
