Development of a replication-defective mpox virus platform for fundamental and therapeutic research.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
The recent global outbreaks of mpox highlight the urgent need for both fundamental research and antiviral development. However, studying the mpox virus (MPXV), with its large and complex genome, remains challenging due to the requirement for high-containment facilities. Here, we describe a strategy for de novo assembly of MPXV clade IIb genomes in bacterial artificial chromosomes using transformation-associated recombination cloning. Leveraging CRISPR-Cas9 and Lambda Red recombination, we engineer replication-defective MPXV particles with dual deletions of OPG96 (M2R) and OPG158 (A32.5 L)-genes essential for virion assembly, that are capable of recapitulating key stages of the viral life cycle. We apply this system to screen a compound library and identify G243-1720, a potent anti-poxvirus inhibitor with broad activity in vitro and in vivo. G243-1720 blocks the formation of extracellular enveloped virions and cell-cell spread. Resistance mutation selection, crystallographic analysis, analytical ultracentrifugation, and mass photometry reveal that, despite its distinct chemical structure, G243-1720 shares a mode of action with tecovirimat, both functioning by affecting dimerization of protein OPG57 (F13). Our findings underscore the potential of G243-1720 as a promising broad-spectrum anti-poxvirus lead compound and demonstrate the utility of replication-defective MPXV particles as a reliable platform for viral biology studies and antiviral development.
