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

We investigated a novel SLAMF7-promoter driven oncolytic adenovirus (Ad[CE1A]) as a potential therapeutic for multiple myeloma, an incurable hematological malignancy. Ad[CE1A] infection, replication, and oncolysis were assessed in a panel of myeloma cell lines (n = 8) and ex vivo samples from myeloma patients (n = 17) and healthy donors (HDs) (n = 14). Ad[CE1A] efficiently infected, replicated, and induced oncolysis in myeloma cells, but not in control cell lines or HDs, demonstrating selective cytotoxicity. Mechanistic studies revealed Ad[CE1A]-induced cell death is caspase-independent, with a potential involvement of necroptosis. Ad[CE1A] also altered immunogenic cell death markers (calreticulin, CD47, extracellular ATP), enhanced antigen presentation via increased MHC class I and II receptor expression (HLA-ABC and HLA-DR), and stimulated bystander cytokine killing, indicating potential for direct and immune-mediated anti-myeloma responses. In vivo experiments with 5TGM1 syngeneic and U266 xenograft models showed Ad[CE1A] significantly reduced myeloma tumor burden compared to vehicle control. Combination therapy with anti-myeloma drugs, bortezomib, melphalan, panobinostat and pomalidomide, enhanced Ad[CE1A] efficacy, with melphalan upregulating SLAMF7, resulting in increased viral replication. In summary, these findings support Ad[CE1A] as a promising myeloma therapy.
