Evaluating therapeutic plasma exchange and protease inhibitors as mechanisms to reduce soluble mesothelin.
Article in Scientific reports, 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
Cell surface mesothelin (MSLN) can be solubilized and released into the systemic circulation. The resulting soluble MSLN (sMSLN) may interfere with therapies targeting surface MSLN. We investigated the effects of sMSLN on anetumab, an antibody-based therapy against MSLN, anetumab ravtansine, an antibody drug conjugate, and mechanisms to decrease sMSLN. Whole blood samples were collected before and after one plasma volume of therapeutic plasma exchange (TPE). sMSLN levels were measured with ELISA assays in matched pre- and post-TPE plasma samples, and anetumab-immunoprecipitated samples. We also used protease inhibitors (PIs) as a mechanism to stabilize surface MSLN, then evaluated the cytotoxic effects of anetumab ravtansine. Our findings indicate that sMSLN sequesters and may impair the efficacy of this anti-MSLN antibody based on results showing that anetumab decreases the concentration of MSLN in plasma (p < 0.05) and reduced cytotoxicity of anetumab ravtansine in the presence of recombinant MSLN in cell lines, a surrogate for sMSLN. TPE consistently reduced sMSLN (p < 0.05) with an average decrease of 43.6% (15.4 ng/mL). Surface MSLN stabilization was inconsistently observed with PIs. Overall, sMSLN could represent a predictive biomarker for MSLN directed therapies. TPE may be more reliable than PIs to reduce sMSLN and ultimately restore sensitivity to these therapies in patients with high sMSLN.
