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

unlabelledHepatitis C virus (HCV) is a major cause of chronic liver disease. Despite recent success in improving anti-HCV therapy, additional progress is still needed to develop cheaper and interferon (IFN)-free treatments. Here, we report that ferroquine (FQ), an antimalarial ferrocenic analog of chloroquine, is a novel inhibitor of HCV. FQ potently inhibited HCV infection of hepatoma cell lines by affecting an early step of the viral life cycle. The antiviral activity of FQ on HCV entry was confirmed with pseudoparticles expressing HCV envelope glycoproteins E1 and E2 from six different genotypes. In addition to its effect on HCV entry, FQ also inhibited HCV RNA replication, albeit at a higher concentration. We also showed that FQ has no effect on viral assembly and virion secretion. Using a binding assay at 4°C, we showed that FQ does not prevent attachment of the virus to the cell surface. Furthermore, virus internalization was not affected by FQ, whereas the fusion process was impaired in the presence of FQ as shown in a cell-cell fusion assay. Finally, virus with resistance to FQ was selected by sequential passage in the presence of the drug, and resistance was shown to be conferred by a single mutation in E1 glycoprotein (S327A). By inhibiting cell-free virus transmission using a neutralizing antibody, we also showed that FQ inhibits HCV cell-to-cell spread between neighboring cells. Combinations of FQ with IFN, or an inhibitor of HCV NS3/4A protease, also resulted in additive to synergistic activity.

conclusionFQ is a novel, interesting anti-HCV molecule that could be used in combination with other direct-acting antivirals.
