When one plus one means more than two: the blockade of both IL-4 and IL-13 inflammatory pathways with dupilumab in a case of severe refractory T2-high asthma.

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.
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
Novel approach of asthma includes personalised therapy involving specific immune pathways. We describe here a case of T2-high asthma in a 66-year-old woman treated with maximal inhaled therapy and inappropriate usage of oral corticosteroids showing poor symptoms control. Both anti-IgE and (omalizumab) and anti-interleukin (IL)-5 (mepolizumab) monoclonal antibodies treatments were prescribed without significant benefit. Add-on subcutaneous dupilumab, a monoclonal antibody directed against the IL-4 receptor subunit alpha, inhibiting signalling from both IL-4 and IL-13, proved to be an effective and safe medication to obtain rapid asthma control. Considering the previous lack of response to both anti-IgE and anti-eosinophilic strategies, we hypothesise that dupilumab upstream activity could exert different and more relevant effects than the simple inhibition of the two single downstream pathways. The current case highlights the need for a deeper analysis of biomolecular interactions in the framework of different asthma endotypes, to identify peculiar profiles associated with specific treatment responses.
