RESUMEN
BACKGROUND: Tildrakizumab is a humanized, IgG1/κ antibody that interacts with the p19 subunit of interleukin 23. It is approved for the treatment of moderate-to-severe plaque psoriasis. Real-world evidence on the effectiveness and safety of tildrakizumab is limited. OBJECTIVES: To assess the effectiveness and safety of tildrakizumab at 24 weeks in patients with moderate-to-severe plaque psoriasis in routine clinical practice. METHODS: Retrospective, observational, multicentre study including adult patients with moderate-to-severe plaque psoriasis treated with tildrakizumab under real-life conditions. Patient data were extracted from anonymized electronic medical records. Statistical analysis was performed using SPSS22. RESULTS: A total of 190 patients were included. About 53.9% were men with a mean age of 51.45 (SD 3.9) and a mean BMI of 29.13 (SD 6.21). About 79.8% (132 out of 190) of patients had previously received biological therapy (BT) and 17.3% (33 out of 191) had psoriatic arthritis. Baseline PASI was 10.7 (SD 6.53). Up to 109 patients reached Week 24 and at this point mean baseline PASI decreased to 1.7 (SD 4.8), representing an 88.79% mean PASI reduction. At 6 months, 87.1% and 40.3% of the treated patients achieved PASI ≤3 and ≤1, respectively. At Week 24 mean BSA decreased from 13.2 (SD 10.07) to 1.6 (SD 4.40) and mean DLQI went from 12.5 (SD 7.12) to 1.2 (SD 3.27). Multivariate analysis showed no differences when effectiveness was correlated with gender, obesity, psoriatic arthritis or prior exposure to BT. The rate of adverse events (AE) was 5.9% (11 out of 190), where infections were the most frequent AE (4 out of 11). One patient suffered a haemorrhagic ictus and one patient died due to causes unrelated to the study. CONCLUSION: Tildrakizumab was effective and safe in a large cohort of patients with moderate-to-severe plaque psoriasis treated in a routine clinical setting.

NAVIGATE clinical trial demonstrated a higher rate of Psoriasis Assesment Severity Index (PASI)90 response in patients treated with guselkumab when compared to ustekinumab and an improved response in those who switched from ustekinumab to guselkumab due to partial response. The objective of the study is to describe ustekinumab to guselkumab switching in clinical practice. Observational, multicentric, descriptive study including 54 psoriasis patients who switched to guselkumab after treatment with ustekinumab from March 2019 to February 2021. Mean basal PASI with ustekinumab (16.7) was higher than with guselkumab (7.2). Up to 49.01% of patients were able to reach PASI90 with ustekinumab and up to 21.56% had a less frequent dosage regime vs. summary of product characteristics. Main reason to start guselkumab was a loss of ustekinumab cutaneous or articular response (82.36%) but up to 17.64% were switched in order to increase dosage regime efficiency. Six months after starting guselkumab, the absolute PASI was lower than 2 in 72% of patients and 38.5% of them were treated with a reduced dosage regime. Guselkumab doses used by our cohort were 19.5% lower than the expected according to the summary of product characteristics. No adverse events reported. There is no real-world evidence regarding patients who switched from ustekinumab to guselkumab. A short paragraph in the article by Fougerousse et al, reported 63 patients with a mean basal PASI of 5.3 and similar efficacy rate at week 16 to NAVIGATE. Our study adds practical information regarding efficacy, safety and efficiency through dose optimization in a real-world cohort.
