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

Murine double minute 2 (MDM2) has long been a therapeutic target to stabilize and upregulate wild-type tumor protein 53 (p53) in cancer. We initially reported WB156 as a degrader of MDM2 that can upregulate p53 levels in acute leukemia. To further evaluate the therapeutic potential of WB156, we tested it in a variety of cancers alongside another reported MDM2 degrader. We found that WB156 is active in wild-type and mutant p53-bearing leukemias due to its ability to degrade both MDM2 and G1 To S Phase Transition 1 (GSPT1) protein. In cancers that are non-responsive to MDM2 degradation alone, WB156 acts as a GSPT1 degrader to induce anti-proliferative effects. Here, we report the first MDM2/GSPT1 dual degrader that also upregulates p53 levels.
