Novel Trispecific Neutralizing Antibodies With Enhanced Potency and Breadth Against Pan-Sarbecoviruses.
Article in MedComm, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 ongoing emergence of new variants of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) underscores the urgent need for developing antivirals targeting both SARS-CoV-2 variants and related sarbecoviruses. To this end, we designed novel trispecific antibodies, Tri-1 and Tri-2, engineered by fusing the single-chain variable fragments (scFvs) of a potent antibody (PW5-570) to the Fc region of "Knob-into-Hole" bispecific antibodies (bsAbs) composed of two distinct broad antibodies (PW5-5 and PW5-535). Compared with the parental antibodies, Tri-1 and Tri-2 displayed enhanced binding affinities to the receptor-binding domains of SARS-CoV, SARS-CoV-2 wild type, and Omicron XBB.1.16, with each arm contributed to the overall enhancement. Furthermore, pseudovirus neutralization assays revealed that Tri-1 and Tri-2 effectively neutralized all tested SARS-CoV, SARS-CoV-2 variants, and related sarbecoviruses (Pangolin-GD, RaTG13, WIV1, and SHC014), demonstrating potency and breadth superior to any single parental antibody. Consistently, Tri-1 and Tri-2 were found to effectively neutralize authentic SARS-CoV and SARS-CoV-2 variants with IC
