Improved targeted delivery of antisense oligonucleotide with an antibody mask.
Article in Nucleic acids research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Antisense oligonucleotides (ASOs) are synthetic nucleic acid strands designed to modulate gene expression by binding to RNA transcripts. In brain diseases, transferrin receptor (TfR)-targeting antibody-ASO conjugates have shown promise for brain delivery of ASOs via transcytosis in preclinical studies. This enables the more patient friendly intravenous or subcutaneous administration of the compounds. However, these conjugates can exhibit faster plasma clearance and different peripheral pharmacokinetic profiles due to ASO modifications, such as phosphorothioate (PS) linkages and locked nucleic acids (LNAs). In this study, we employed an antibody recognizing LNA- and PS-modified ASOs independent of the base sequences as a cloaking module to mitigate these issues. Using Kutzneria albida transglutaminase (KTG) technology and click chemistry, we generated TfR antibody-ASO conjugates with covalently or noncovalently incorporated ASO binders. Additionally, a noncovalent carrier antibody approach was explored. These conjugates and complexes with additional ASO binder(s) show improved TfR-targeted cellular uptake, undergo transcytosis in cellular blood-brain barrier models, show less nonspecific cellular accumulation, and anticipated ASO activity.
