Janus kinase 1 inhibitors for treating immune checkpoint inhibitor-induced enterocolitis - report of two filgotinib-treated cases and literature review.

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
background and purposeTreatment of cancer with immune checkpoint inhibitors (ICIs) entails a risk of immune-related adverse events (irAEs). Data on the treatment of immune-related enterocolitis (irEC) in patients with inadequate symptom control after treatment with standard therapy including corticosteroids, infliximab, and vedolizumab are scarce. Based on limited data, recommendations include treatment with the pan-Janus kinase (JAK) inhibitor tofacitinib. Filgotinib is a more recently developed JAK inhibitor with preferential inhibition of JAK1, which might imply a more favorable safety profile. Filgotinib is approved for the treatment of ulcerative colitis and might thus be an option in refractory irEC. PATIENTS AND
methodsWe present two cases of metastatic melanoma treated with ICIs who developed corticosteroid and infliximab-refractory irEC. Given non-conventional pharmaceutical management, literature review was performed regarding mechanisms of action and safety profiles of JAK inhibitors.
resultsBoth patients were treated with filgotinib, which resulted in rapid remission of symptoms in both cases. One of the patients was treated with off-label high-dose filgotinib, which has not been described previously. The rationale and safety regarding the use of JAK1 inhibitors in irAEs are discussed, including the seemingly diverging existing data on potential effects of JAK inhibition on ICI-induced anti-tumoral immune-responses. In addition, the rationale for the high-dose treatment is scrutinized.
interpretationThis report suggests that filgotinib may be considered for treating irEC refractory to standard therapy.
