Patient-Reported Well-Being in Value-Based Routine Care Using Tildrakizumab: 52-week Interim Data of the Phase IV Positive Study

Purpose: Psoriasis profoundly impairs patients' social, emotional, and physical condition, impacting on their overall well-being. Tildrakizumab is an interleukin-23p19 inhibitor labelled for the treatment of moderate-to-severe plaque psoriasis. The main objective of this study was to assess the effect of tildrakizumab on the overall well-being of people with psoriasis. Effectiveness, quality of life (QoL), symptomatology, treatment satisfaction, and the impact of psoriasis on the patients' partners were also evaluated. Patients and methods: POSITIVE is a 24-month observational study in adults with moderate-to-severe psoriasis treated with tildrakizumab in a real-world setting (ClinicalTrials.gov ID: NCT04823247). Outcome measurements included the 5-item WHO Well-being Index (WHO-5), Psoriasis Area and Severity Index (PASI), Dermatology Life Quality Index-Relevant (DLQI-R), Treatment Satisfaction Questionnaire for Medication (TSQM-9), and FamilyPso. We report 52-week (W52) interim data (N = 400; observed cases). Conclusion: Tildrakizumab successfully contributes to value-based long-term health care for moderate-to-severe psoriasis by increasing patient wellbeing, QoL and clinical outcomes while showing very good safety and tolerability.
