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

background and purposeThe SARS-COV-2 pandemic and the global spread of coronavirus disease 2019 (COVID-19) urgently call for efficient and safe antiviral treatment strategies. A straightforward approach to speed up drug development at lower costs is drug repurposing. Here, we investigated the therapeutic potential of targeting the interface of SARS CoV-2 with the host via repurposing of clinically licensed drugs and evaluated their use in combinatory treatments with virus- and host-directed drugs in vitro. EXPERIMENTAL APPROACH: We tested the antiviral potential of the antifungal itraconazole and the antidepressant fluoxetine on the production of infectious SARS-CoV-2 particles in the polarized Calu-3 cell culture model and evaluated the added benefit of a combinatory use of these host-directed drugs with the direct acting antiviral remdesivir, an inhibitor of viral RNA polymerase. KEY

resultsDrug treatments were well-tolerated and potently impaired viral replication. Importantly, both itraconazole-remdesivir and fluoxetine-remdesivir combinations inhibited the production of infectious SARS-CoV-2 particles > 90% and displayed synergistic effects, as determined in commonly used reference models for drug interaction. CONCLUSION AND IMPLICATIONS: Itraconazole-remdesivir and fluoxetine-remdesivir combinations are promising starting points for therapeutic options to control SARS-CoV-2 infection and severe progression of COVID-19.
