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

Obeldesivir (ODV; GS-5245) is an orally administered ester prodrug of the parent nucleoside GS-441524 that has broad spectrum antiviral activity inhibiting viral RNA-dependent RNA polymerases. We recently showed that ODV completely protects cynomolgus macaques against lethal infection with Sudan virus when given 24 hours after parenteral exposure. Here, we report that once daily oral ODV treatment of cynomolgus and rhesus macaques for 10 days confers 80 and 100% protection, respectively, against lethal Ebola virus infection when treatment is initiated 24 hours after mucosal (conjunctival) exposure. ODV treatment delayed viral replication to abate excessive inflammation and promote adaptive immunity. For outbreak response, oral antivirals might present substantial advantages over now approved intravenous drugs, such as easy supply, storage, distribution, and administration. Furthermore, these results support the potential of ODV as an oral postexposure prophylaxis with broad spectrum activity across filoviruses.
