Expedited Desensitization to Canakinumab.

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
introductionInterleukin-1 (IL-1) antagonists have been successful in the management of monogenic auto-inflammatory diseases, notably classic hereditary fever syndromes, such as Familial Mediterranean Fever (FMF). Anakinra (Kineret®), a human recombinant IL-1 receptor antagonist (IL-1Ra), has been clinically effective in the management of persistent auto-inflammation, such as FMF. Few studies report anaphylaxis in response to anakinra, which were resolved with an anakinra desensitization or the anti-IL-1β monoclonal antibody canakinumab (ILARIS®). We describe the first reported desensitization protocol to canakinumab. CASE REPORT: A 51-year-old man with a prior history of FMF presented with history of failed colchicine, nonsteroidal anti-inflammatory drug, and anakinra trials. Anakinra desensitization and canakinumab intradermal testing (IDT) resulted in anaphylactic and allergic symptoms, respectively. Expedited desensitization to canakinumab was successfully performed with 15-minute intervals between 13 doses of incremental increase to 150 mg. DISCUSSION: Biological agents are immune modulators that may evoke unanticipated hypersensitivity reactions, including anaphylaxis. These anaphylactic reactions to biologics have been infrequently reported, but the expanding market may increase the risk of IgE-mediated hypersensitivities and subsequent need for desensitization protocols. The current, expedited desensitization evaluated several published protocols involving anakinra desensitization to determine appropriate dosing for canakinumab.
conclusionWe report the gastrointestinal intolerance and continued FMF flares on colchicine, followed by anaphylactic responses to anakinra and allergic reaction to IDT of canakinumab, in the present case of FMF. Our novel, expedited canakinumab desensitization protocol serves as an effective and alternative therapy in cases when other appropriate biologic agents are not tolerated.
