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

Glioblastoma (GBM) is the most common and aggressive brain malignancy in adults and is currently incurable with conventional therapies. The use of chimeric antigen receptor (CAR) modified T cells has been successful in clinical treatment of blood cancers, except solid tumors such as GBM. This study generated two third-generation CARs targeting different epitopes of ephrin type-A receptor 2 (EphA2) and examined their anti-GBM efficacy in vitro and in tumor-bearing mice. We observed that these two types of T cells expressing CAR (CAR-T) targeting EphA2 could be activated and expanded by EphA2 positive tumor cells in vitro. The survival of tumor-bearing mice after EphA2 CAR-T cell treatment was significantly improved. T cells transduced with one of the two EphA2 CARs exhibited better anti-tumor activity, which is related to the upregulation of CXCR-1/2 and appropriate interferon-γ (IFN-γ) production. CAR-T cells expressed excessively high level of IFN-γ exhibited poor anti-tumor activity resulting from inducing the upregulation of PD-L1 in GBM cells. The combination of CAR-T cells with poor anti-tumor activity and PD1 blockade improved the efficacy in tumor-bearing mice. In conclusion, both types of EphA2 CAR-T cells eliminated 20%-50% of GBM in xenograft mouse models. The appropriate combination of IFN-γ and CXCR-1/2 levels is a key factor for evaluating the antitumor efficiency of CAR-T cells.
