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

Mucopolysaccharidosis type I (MPS I) is a progressive lysosomal storage disorder with systemic and central nervous system (CNS) involvement due to deficiency of α-L-iduronidase (IDUA). We previously identified a receptor-binding peptide from apolipoprotein E (e) that facilitated a widespread delivery of IDUAe fusion protein into CNS. In this study, we evaluated the long-term CNS biodistribution, dose-correlation, and therapeutic benefits of IDUAe after systemic, sustained delivery via hematopoietic stem cell (HSC)-mediated gene therapy with expression restricted to erythroid/megakaryocyte lineages. Compared to the highest dosage group treated by nontargeted control IDUAc (165 U/ml), physiological levels of IDUAe in the circulation (12 U/ml) led to better CNS benefits in MPS I mice as demonstrated in glycosaminoglycan accumulation, histopathology analysis, and neurological behavior. Long-term brain metabolic correction and normalization of exploratory behavior deficits in MPS I mice were observed by peripheral enzyme therapy with physiological levels of IDUAe derived from clinically attainable levels of HSC transduction efficiency (0.1). Importantly, these levels of IDUAe proved to be more beneficial on correction of cerebrum pathology and behavioral deficits in MPS I mice than wild-type HSCs fully engrafted in MPS I chimeras. These results provide compelling evidence for CNS efficacy of IDUAe and its prospective translation to clinical application.
