Pharmacokinetics of IL-23p19 Inhibitors: A Systematic Review Across Immune-Mediated Inflammatory Diseases.
Synthesis in Clinical pharmacokinetics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundInterleukin (IL)-23p19 inhibitors are increasingly used in immune-mediated inflammatory diseases (IMIDs), particularly inflammatory bowel disease (IBD). Almost half of patients show inadequate response, partly due to pharmacokinetic (PK) variability. However, a comprehensive overview of their PK parameters is lacking, which limits understanding of population variability. This systematic review assessed the PK of IL-23p19 inhibitors in healthy subjects, IBD and other IMIDs.
methodsA systematic literature search was performed in PubMed/MEDLINE and Embase. Studies were screened by two independent researchers. Quality was assessed using the Cochrane risk of bias tool and the Clinical Pharmacokinetic Study Checklist.
resultsA total of 21 studies were included (risankizumab n = 9, guselkumab n = 6, tildrakizumab n = 3, mirikizumab n = 3), covering healthy subjects, psoriasis, psoriatic arthritis, Crohn's disease (CD), ulcerative colitis (UC) and pustular/erythrodermic psoriasis. Only one study examined a distinct IBD group, specifically, mirikizumab in pediatric UC. For risankizumab, dose-normalized maximum concentrations and area under the concentration‑time curves over a dosing interval, along with central and peripheral volume of distribution and clearance were generally similar across CD and UC. Patients with CD and UC demonstrated increased risankizumab trough levels over consecutive dosing intervals, while an opposite trend was observed for other IMIDs. Covariate analysis revealed that only albumin in UC and body weight in CD were relevant covariates to risankizumab PK.
conclusionLimited PK data and lack of subphenotype-specific data on IBD highlight the need for future studies to better define PK parameters. Also, more research is needed to guide personalized dosing strategies for IL-23p19 inhibitor use in IBD, as well as in other IMIDs.
