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

Mutations in genes in the retinal pigment epithelium (RPE) cause or contribute to debilitating ocular diseases, including Leber's congenital amaurosis (LCA). Genetic therapies, particularly adeno-associated viruses (AAVs), are a popular choice for monogenic diseases; however, the limited payload capacity of AAVs combined with the large number of retinal disease genes exceeding that capacity make the development of alternative delivery methods critical. Here, we test the ability of compacted DNA nanoparticles (NPs) containing a plasmid with a scaffold matrix attachment region (S/MAR) and vitelliform macular dystrophy 2 (VMD2) promoter to target the RPE, drive long-term, tissue-specific gene expression and mediate proof-of-principle rescue in the rpe65(-/-) model of LCA. We show that the S/MAR-containing plasmid exhibited reporter gene expression levels several fold higher than plasmid or NPs without S/MARs. Importantly, this expression was highly persistent, lasting up to 2 years (last timepoint studied). We therefore selected this plasmid for testing in the rpe65(-/-) mouse model and observe that NP or plasmid VMD2-hRPE65-S/MAR led to structural and functional improvements in the LCA disease phenotype. These results indicate that the non-viral delivery of hRPE65 vectors can result in persistent, therapeutically efficacious gene expression in the RPE.
