1 · What the graph read from it

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.

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.

Abstract

AIM &

methodsTRK-950, a humanized IgG1 monoclonal antibody against CAPRIN-1, which is reported to be expressed on the cell surface of various forms of cancer, is currently being developed for multiple types of solid cancer. We developed an antidrug antibody (ADA) assay that includes two pretreatment processes for use in clinical trials, namely, Melon™ gel treatment and solid-phase extraction with acid dissociation (SPEAD), to reduce baseline variability between individual serum samples and improve drug tolerance.

resultsComparing the assay with or without the pretreatment process using commercially available human serum samples, the mean response calculated from 18 individual human samples decreased from 327 to 270, and the coefficient of variation decreased from 41% to 16%. The new assay with the two-step pretreatment met the criteria set by the regulatory agency throughout the validation study. We also confirmed the recovery rates of IgG, IgM, and ADA - drug immune complexes after treatment with Melon™ gel. Clinical trials (NCT05423262) employing this improved analytical method have been conducted, and the results confirm the low immunogenicity of TRK-950.

conclusionThe combination of pretreatment with Melon™ gel and SPEAD is applicable for clinical ADA assays.
