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

Therapies that synergistically stimulate immunogenic cancer cell death (ICD), inflammation, and immune priming are of great interest for cancer immunotherapy. However, even multi-agent therapies often fail to trigger all of the steps necessary for self-sustaining anti-tumor immunity. Here we describe self-replicating RNAs encapsulated in lipid nanoparticles (LNP-replicons), which combine three key elements: (1) an LNP composition that potently promotes ICD, (2) RNA that stimulates danger sensors in transfected cells, and (3) RNA-encoded IL-12 for modulation of immune cells. Intratumoral administration of LNP-replicons led to high-level expression of IL-12, stimulation of a type I interferon response, and cancer cell ICD, resulting in a highly inflamed tumor microenvironment and priming of systemic anti-tumor immunity. In several mouse models of cancer, a single intratumoral injection of replicon-LNPs eradicated large established tumors, induced protective immune memory, and enabled regression of distal uninjected tumors. LNP-replicons are thus a promising multifunctional single-agent immunotherapeutic.
