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

Adult T-cell leukemia/lymphoma (ATL) develops from the infection of T cells with human T lymphotropic virus type 1 (HTLV-1). There are an estimated 5-20 million HTLV-1 carriers worldwide and the patients are frequently observed in subtropical Africa, the Caribbean, Middle East, South America, and South West Japan. The prognosis of ATL remains dismal due to rapid acquired resistance to treatment with cytotoxic chemotherapeutic agents. In particular, the development of novel therapies for relapsed or refractory (R/R) ATL is an unmet need. Previous clinical trials revealed that bendamustine (BDM) was effective as the first-line treatment for indolent lymphoma and R/R cases of diffuse large B-cell lymphoma. Its major advantage is that it has few side effects such as hair loss and peripheral neuropathy, and does not impair the quality of life. However, its efficacy has not been verified for ATL in pre-clinical or clinical studies. In this study, we have shown the cytotoxicity of BDM alone and in combination with novel agents including the histone deacetylase (HDAC) inhibitor tucidinostat, the enhancer of zeste homolog 1/2 (EZH1/2) dual inhibitor valemetostat, and the Bcl2 family inhibitor ABT-737. The combined in vitro effects of BDM and tucidinostat were reproduced in a murine model without any obvious hematological toxicity. Our present results suggest that the combination of tucidinostat and BDM could additively prolong the survival of patients with R/R progressive ATL. The efficacy and safety of this combination are thus worthy of investigation in clinical settings.
