Tildrakizumab is an anti-interleukin-23 p19 monoclonal antibody approved for the treatment of moderate-to-severe plaque psoriasis. This report describes final primary results of a 64-week real-world study of the effect of tildrakizumab on patients' health-related quality of life (HRQoL).
In this open-label phase 4 study (NCT03718299), patients with moderate-to-severe plaque psoriasis received tildrakizumab 100 mg at week 0, week 4, and every 12 weeks thereafter through week 52. The primary endpoint was improvement from baseline in HRQoL measured by Psychological General Well-Being Index (PGWBI) total score at weeks 28 and 52. Secondary HRQoL endpoints included change from baseline in Dermatology Life Quality Index (DLQI) score through week 64. Missing data were not imputed.
Of 55 patients enrolled, 45 were assessed at week 64. Mean ± standard deviation (SD) total PGWBI score improved from 78.1 ± 14.1 at baseline to 85.2 ± 12.0 at week 52 (
 < .001). Mean ± SD DLQI score improved from 9.4 ± 5.2 at baseline to 2.0 ± 2.6 (
 < .001) at week 64 with 62.2% of patients having a DLQI score of 0 or 1 at week 64.
Tildrakizumab improved long-term HRQoL in patients with psoriasis in a real-world setting.
