Auristatin S: An Auristatin Payload with Improved Tolerability and Modified Bystander Activity.
Article in ACS medicinal chemistry letters, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Auristatins are a class of antibody-drug conjugate (ADC) payloads employed in anticancer therapies. Auristatin payloads are clinically validated and effective, but opportunities remain to improve their clinical benefit. Here, we describe the development and characterization of a new auristatin payload, Auristatin S, that demonstrates robust efficacy and improved off-target toxicity. This effort focused on the optimization of bystander activity, which is a key property that modulates the efficacy and tolerability of the ADC payloads. In vitro screening of tubulin binding, free drug cytotoxicity, and ADC activity were utilized to characterize the bystander activity profile. The corresponding peptide-linked conjugates showed excellent on-target cytotoxicity against cancer cells and induction of immunogenic cell death. Tolerability of Auristatin S was improved relative to historical controls, and in vivo activity and bystander activity were confirmed in a Karpas/KarpasBVR model.
