TOPLINE:
In a retrospective cohort study, treatment with an IL-23 inhibitor was associated with a similar incidence of psoriatic arthritis (PsA) as treatment with IL-2/23 inhibitors in patients with psoriasis.
METHODOLOGY:
- In the study, researchers evaluated adults with psoriasis (average age, 46 years) in the TriNetX research network.
- Patients received either an IL-23 inhibitor (n = 2273; guselkumab, tildrakizumab, or risankizumab) or an IL-12/23 inhibitor (n = 2995; ustekinumab).
- The study outcome was the onset of PsA.
TAKEAWAY:
- In propensity matched cohorts, the risk for PsA was not statistically different among patients treated with an IL-23 inhibitor and those treated with an IL-12/23 inhibitor (hazard ratio, 0.96; P = .812).
- No statistically significant differences in risk between the two groups were seen in demographic subgroups, although sample sizes were small.
- The cumulative incidence of PsA was not significantly different between the two groups (P = .812), with the IL-23 inhibitor–treated cohort showing marginally higher rates between years 3 and 5.
IN PRACTICE:
The results underscore the “comparable efficacy” of IL-23 and IL-12/23 inhibitors for patients with psoriasis, the authors wrote, adding that more research with larger cohorts and longer follow-ups “is essential to further our understanding of these therapies’ long-term effectiveness.”

LIMITATIONS:
Study limitations included misclassification and the retrospective design. The numbers of Black and Asian patients were small, limiting subgroup analysis.
DISCLOSURES:
The study was not supported by any funding sources. The authors declared no conflicts of interest.
