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

Oral delivery of peptide therapeutics faces multiple challenges due to their instability in the gastrointestinal tract and low permeation capability. In this study, the aim is to develop a liposomal nanocarrier formulation to enable the oral delivery of the vancomycin-peptide derivative FU002. FU002 is a promising, resistance-breaking, antibiotic which exhibits poor oral bioavailability, limiting its potential therapeutic use. To increase its oral bioavailability, FU002 is incorporated into tetraether lipid-stabilized liposomes modified with cyclic cell-penetrating peptides on the liposomal surface. This liposomal formulation shows strong binding to Caco-2 cells without exerting cytotoxic effects in vitro. Pharmacokinetics studies in vivo in rats reveal increased oral bioavailability of liposomal FU002 when compared to the free drug. In vitro and in vivo antimicrobial activity of FU002 are preserved in the liposomal formulation. As a highlight, oral administration of liposomal FU002 results in significant therapeutic efficacy in a murine systemic infection model. Thus, the presented nanotechnological approach provides a promising strategy for enabling oral delivery of this highly active vancomycin derivative.
