Treatment efficacy and patient satisfaction of ustekinumab compared with tumor necrosis factor-alpha inhibitors in Chinese patients with moderate-to-severe psoriasis: a real-world study.

Background: Ustekinumab is an interleukin (IL)-12/IL-23 inhibitor for the treatment of moderate-to-severe psoriasis.

Objective: This real-world study compared ustekinumab and tumor necrosis factor-alpha inhibitors (TNFis) in Chinese moderate-to-severe psoriasis patients.

Methods: Patient health records of 110 moderate-to-severe psoriasis patients initiating or switching biologics were reviewed, with 31 patients receiving ustekinumab (ustekinumab group) and 79 patients receiving TNFis (TNFi group).

Results: Compared with TNFi group, psoriasis area and severity index (PASI)-75 response rate at month 6 (M6) were elevated (87.1% versus 65.8%, p = 0.026) in the ustekinumab group, whereas the rates at month 1 (M1) and month 3 (M3) and PASI-90 response rates at M1, M3, and M6 only showed an increasing trend (all p > 0.050) in the ustekinumab group than the TNFi group. By subgroup analyses, ustekinumab (versus TNFi) was more effective in patients with biologics therapy history than those without. Compared with the TNFi group, the ustekinumab group had lower dermatology life quality index scores and higher patient satisfaction scores at M3 and M6 (all p < 0.050).

Conclusion: Chinese moderate-to-severe psoriasis patients treated with ustekinumab have a better treatment response at 6 months with improved quality of life and patient satisfaction after 3-6 months of treatment when compared to TNFi.
