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.

2 · The registry

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 immunosuppressive effects of CD4+ CD25 high regulatory T cells (Tregs) interfere with antitumor immune responses in cancer patients. Here, we present a novel class of engineered human interleukin (IL)-2 analogs that antagonizes the IL-2 receptor, for inhibiting regulatory T cell suppression. These antagonists have been engineered for high affinity to the alpha subunit of the IL-2 receptor and very low affinity to either the beta or gamma subunit, resulting in a signaling-deficient IL-2 analog that sequesters the IL-2 receptor alpha subunit from wild type IL-2. Two variants, "V91R" and "Q126T" with residue substitutions that disrupt the beta and gamma subunit binding interfaces, respectively, have been characterized in both a T cell line and in human primary Tregs. These mutants retain their high affinity binding to IL-2 receptor alpha subunit, but do not activate STAT5 phosphorylation or stimulate T cell growth. The 2 mutants competitively antagonize wild-type IL-2 signaling through the IL-2 receptor with similar efficacy, with inhibition constants of 183 pM for V91R and 216 pM for Q126T. Here, we present a novel approach to CD25-mediated Treg inhibition, with the use of an engineered human IL-2 analog that antagonizes the IL-2 receptor.
