Tildrakizumab, an anti-IL-23 mAb, is approved for the treatment of moderate-to-severe plaque psoriasis in adult patients.1 A phase IV real-world, open-label, US-based study (NCT03718299) was initiated to evaluate the effect of tildrakizumab on HRQoL in patients with plaque psoriasis. A total of 55 patients were enrolled; 45 patients completed 64 weeks of treatment and were subsequently assessed. The primary endpoint was improvement in PGWBI from baseline. Changes to DLQI and safety outcomes were also assessed.1

Key learnings |
Significant improvements were observed in PGWBI and DLQI. The mean PGWBI score improved over time, increasing from 78.1 at baseline to 85.2 at Week 52 (p < 0.001). Mean DLQI score improved from 9.4 to 2.0 by Week 64 (p < 0.001). |
Significant improvements were seen in the PGWBI subdomains of positive well-being and general health. Other domains, such as anxiety and depression, showed improvement trends. |
At Week 64, 62.2% of patients reported minimal or no impact of psoriasis on their QoL (DLQI 0/1). These improvements were evident from Week 4, indicating rapid and sustained benefits, with the proportion of patients achieving DLQI 0/1 increasing over time. |
Overall, tildrakizumab demonstrated long-term effectiveness in enhancing both psychological and skin-related QoL, with no adverse events reported relating to tildrakizumab treatment. This real-world evidence strengthens confidence in tildrakizumab as a treatment for improving patient-reported outcomes. |
