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

CAR-T-cell therapy has shown considerable advance in recent years, being approved by regulatory agencies in US, Europe, and Japan for the treatment of refractory patients with CD19+ B-cell leukemia or diffuse large B-cell lymphoma. Current methods for CAR-T-cell production use viral vectors for T-cell genetic modification and can take up to 15 days to generate the infusion product. The development of simple and less costly manufacturing protocols is needed in order to meet the increasing demand for this therapy. In this present work, we generated 19BBz CAR-T cells in 8 days using a protocol based on the non-viral transposon-based vector Sleeping Beauty. The expanded cells display mostly a central memory phenotype, expressing higher levels of inhibitory receptors when compared with mock cells. In addition, CAR-T cells were cytotoxic against CD19+ leukemia cells in vitro and improved overall survival rates of mice xenografted with human RS4;11 or Nalm-6 B-cell leukemias. Infused CAR-T cells persisted for up to 28 days, showing that they are capable of long-term persistence and antitumor response. Altogether, these results demonstrate the effectiveness of our protocol and pave the way for a broader application of CAR-T-cell therapy.
