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

There is a pressing need for novel treatments for substance use disorders to address increasing rates of addiction and drug overdose. Preclinical studies have shown that the orexin (hypocretin) system in the brain, mediated primarily by the orexin 1 receptor, plays a role in reward-related behaviours and that selective blockade of this receptor is efficacious in rodent models of addiction for a wide range of substances including opioids, cocaine, nicotine, and alcohol. We report here the preclinical profile of C4X3256, a novel, selective oral antagonist of the orexin 1 receptor. In the rat, high levels of receptor occupancy were observed in the tenia tecta region of the brain for up to 8 h following oral dosing. Translation of brain receptor occupancy into pharmacological efficacy was demonstrated in rat models showing significantly reduced nicotine self-administration and diminished cue-induced reinstatement of nicotine seeking following an oral dose of 30 mg/kg C4X3256. In addition, C4X3256 significantly reduced reinstatement of cocaine seeking induced by presentation of tone/light cues in a rat model of relapse. In summary, the nonclinical profile of C4X3256 has supported the progression of this compound into human clinical trials as an investigational medicinal product for the treatment of substance use disorders.
