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 heat shock protein 90 (Hsp90) family of molecular chaperones mediates the folding and activation of ~ 400 client proteins, many of which contribute to oncogenesis. As a result, Hsp90 pan-inhibitors, which inhibit all four Hsp90 isoforms, have been investigated in the clinic for the treatment of cancer. Unfortunately, detrimental side effects were observed and hindered the clinical development of pan-Hsp90 inhibitors. The two most common on-target toxicities, cardio-toxicity and ocular-toxicity, have been attributed to inhibition of the Hsp90α isoform. As an alternative strategy, Hsp90β-selective inhibitors have been developed, which have shown promising anti-cancer activity in vitro and in vivo in combination with immune-checkpoint blockade therapy. This study aims to assess the potential risks of cardio-toxicity and ocular-toxicity exhibited by Hsp90β-selective inhibitors in vitro. In summary, the Hsp90β-selective NDNB1182 was found to avoid the cardio- and ocular-toxicity typical of Hsp90 pan-inhibitors (e.g. 17-AAG), providing a promising path toward the generation of isoform-selective Hsp90 inhibitors.
