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

Infusion of T lymphocytes expressing chimeric antigen receptors (CARs) can produce extraordinary antitumor activity in patients with leukemia, lymphoma, and myeloma. The signaling mechanisms activating T cells and provoking tumor cell killing also trigger cytokine secretion and macrophage activation, leading to cytokine release syndrome (CRS). CRS is a serious side effect of CAR-T cells, and proinflammatory interleukin-6 (IL-6) is central to its pathogenesis. To endow T cells with anti-CRS activity, we designed a nonsignaling membrane-bound IL-6 receptor (mbaIL6) constituted by a single chain variable fragment derived from an anti-IL-6 antibody linked to a transmembrane anchoring peptide. We found that mbaIL6 expressed on the surface of T cells could rapidly remove IL-6 from the culture supernatant. IL-6 removal was proportional to the number of mbaIL6+ cells, increased with T-cell proliferation, and neutralized IL-6 signaling and function. A construct encoding for mbaIL6 and an anti-CD19-41BB-CD3ζ CAR allowed simultaneous expression of both receptors. T cells with mbaIL6 and CAR neutralized macrophage-derived IL-6 while exerting powerful antitumor activity. Cytotoxicity and proliferation were identical to those of cells expressing CAR alone in vitro, and CAR-T cells were effective in xenograft models regardless of mbaIL6 expression. Levels of human IL-6 in mice, however, were greatly reduced if T cells expressed both receptors instead of CAR alone. Thus, CAR-T cells with on-board capacity to extinguish IL-6 represent a new approach to prevent CRS and suppress its severity without affecting the antitumor potential of CAR-T cells.
