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 highly restricted expression of B-cell maturation antigen (BCMA) on plasma cells makes it an ideal target for chimeric antigen receptor (CAR) immune cell therapy against multiple myeloma (MM), a bone marrow cancer. To improve the infiltration of ex vivo expanded human natural killer (NK) cells into the bone marrow, we electroporated these cells with mRNA encoding the chemokine receptor CXCR4. The CXCR4-modified NK cells displayed increased in vitro migration toward the bone marrow niche-expressing chemokine CXCL12/SDF-1α and augmented infiltration into the bone marrow compartments in mice. We further modified the CXCR4-NK cells by electroporation of mRNA encoding a CAR targeting BCMA. After the intravenous injection of the double-modified NK cells into a xenograft mouse model of MM, we observed significantly reduced tumor burden in the femur region of the living mice and the extended survival of the tumor-bearing mice. Collectively, this study provides the experimental evidence that the co-expression of CXCR4 and anti-BCMA CAR on NK cells is a possible effective way to control MM progression.
