Interleukin-23p19 inhibitors for the treatment of moderate-to-severe psoriasis: an expert opinion of real-world evidence studies in Europe.

Abstract

Background: Psoriasis is a chronic inflammatory disease affecting about 2% of the global population, with moderate-to-severe forms requiring systemic treatment for successful disease management. By targeting the interleukin (IL)-23p19 subunit of IL-23, the master cytokine of psoriasis pathogenesis, guselkumab, tildrakizumab, and risankizumab offer improved risk-benefit profiles.

Objective: While randomized clinical trials (RCTs) provide controlled data, real-world evidence (RWE) offers insights into the performance of these therapies in diverse patient populations, including those with comorbidities or difficult-to-treat areas affected. With RWE on these inhibitors constantly emerging, a comprehensive overview and expert interpretation are essential for providing key insights into psoriasis management in clinical practice.

Methods: This review, therefore, examined RWE on the effectiveness and safety of IL-23p19 inhibitors compared to their pivotal RCTs.

Results: Despite some gaps between RCT and RWE outcomes, particularly in underrepresented subpopulations, IL-23p19 inhibitors show strong effectiveness and favorable safety across both settings in the short- and especially in the long term, accompanied by an improvement in health-related quality of life and reduction of the main symptoms.

Conclusion: Altogether, these factors make these medicines ideal treatment options. Future research should focus on improving patient-reported outcomes, specifically addressing psychological and quality-of-life aspects, to further optimize psoriasis management.
