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

Clostridioides difficile infection (CDI) remains a significant health threat worldwide. C. difficile is an opportunistic, toxigenic pathogen that takes advantage of a disrupted gut microbiome to grow and produce signs and symptoms ranging from diarrhea to pseudomembranous colitis. Antibiotics used to treat C. difficile infection are usually broad spectrum and can further disrupt the commensal gut microbiota, leaving patients susceptible to recurrent C. difficile infection. There is a growing need for therapeutic options that can continue to inhibit the outgrowth of C. difficile after antibiotic treatment is completed. Treatments that degrade C. difficile toxins while having minimal collateral impact on gut bacteria are also needed to prevent recurrence. Therapeutic bacteria capable of producing a range of antimicrobial compounds, proteases, and other bioactive metabolites represent a potentially powerful tool for preventing CDI recurrence following resolution of symptoms. Here, we describe the identification and initial characterization of ADS024 (formerly ART24), a novel therapeutic bacterium that can kill C. difficile in vitro with limited impact on other commensal bacteria. In addition to directly killing C. difficile, ADS024 also produces proteases capable of degrading C. difficile toxins, the drivers of symptoms associated with most cases of CDI. ADS024 is in clinical development for the prevention of CDI recurrence as a single-strain live biotherapeutic product, and this initial data set supports further studies aimed at evaluating ADS024 in future human clinical trials.
