Biodegradable targeted polymeric mRNA nanoparticles enable in vivo CD19 CAR T cell generation and lead to B cell depletion.

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.
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
While chimeric antigen receptor (CAR) T cell therapies have demonstrated therapeutic efficacy against B cell malignancies, widespread implementation of these therapies is hindered by a cumbersome, ex vivo manufacturing process. Delivery of CAR-encoding messenger RNA (mRNA) to endogenous T cells can generate these therapeutic cells in vivo and streamline this manufacturing workflow. To accomplish this, T cell-activating ligands were conjugated to a biodegradable polymeric mRNA nanoparticle to form T cell-targeted particles. By conjugating multiple activating ligands, T cell transfection and stimulation in vitro was increased, and greater T cell transfection and selectivity in vivo was achieved compared to an untargeted particle. These nanoparticles can flexibly encapsulate mRNA cargos and were used to deliver anti-CD19 CAR mRNA in vivo, enabling depletion of 95% of B cells in the peripheral blood and 50% depletion of splenic B cells in healthy mice. These findings regarding nanoparticle tropism and their potential therapeutic efficacy highlight the importance of this nonviral, polymeric platform to address key limitations associated with current CAR T practices.
