Use of Guselkumab for the Treatment of Moderate-to-Severe Plaque Psoriasis: A 1 Year Real-Life Study.

ABSTRACT: Little information is available from real-life studies evaluating the efficacy of guselkumab in moderate-to-severe psoriasis. In this real-life study, we retrospectively examined a database of 52 patients with moderate-to-severe psoriasis treated with guselkumab (100 mg, s.c.) and followed for 1 year. Disease severity and treatment response was assessed by the Psoriasis Area and Severity Index (PASI) at baseline and after 4, 12, 20, 28, 36, 44, and 52 weeks. Predictors of a PASI response were evaluated by univariate and multivariate regression. After 12 months, 84.2% of patients (mean age 51.3 ± 14.1 years) treated with guselkumab achieved a PASI score of <3. Furthermore, PASI score decreased from 20 ± 13.3 at baseline to 4.4 ± 4.7 and 2.7 ± 3.9 at 12 and 20 weeks, and PASI 75, 90, and 100 response was achieved in 84.2%, 78.9%, and 63.2% of patients respectively at 12 months. Stepwise multivariate regression analysis revealed that previous biological treatment and the presence of comorbidities were associated with poorer response between 28-44 weeks, however the presence of obesity per se was not associated with poorer response. Difficult-to-treat areas were also improved as early as 12 weeks following guselkumab. Guselkumab was observed to be effective and safe in patients with moderate-severe chronic psoriasis in a real world-setting.

Project description:BackgroundReal-life data on patients with psoriasis treated with guselkumab are few and are needed to compare with trial-based data. We investigated the effect of clinical factors on real-world effectiveness of guselkumab.MethodsThis multicentre study retrospectively included 135 patients with psoriasis treated with guselkumab from June 2018 until November 2020. Effectiveness was assessed using the degree of improvement in the Psoriasis Area and Severity Index (PASI) scores at baseline and after 4, 12, 20, 28, and 36 weeks. Predictors of effectiveness were also evaluated.ResultsAt week 36, 67% of the patients achieved PASI 75. Multivariate logistic regression analysis revealed that heavier patients were less likely to achieve PASI 75 at week 4 than patients with lower body weights. Fewer patients exposed to only one biologic achieved PASI 75 at weeks 4, 20, 28, and 36 [odds ratio (OR) = 0.08 (95% CI, 0.01-0.48), 0.21 (95% CI, 0.05-0.74), 0.04 (95% CI, 0.00-0.35), and 0.07 (95% CI, 0.00-0.68), respectively] than biologic-naïve patients. Patients previously treated with more than one biologic were less likely to achieve PASI 75 at weeks 12, 20, 28, and 36 [OR = 0.05 (95% CI, 0.01-0.22), 0.03 (95% CI, 0.01-0.16), 0.00 (95% CI, 0.00-0.03), and 0.00 (95% CI, 0.00-0.044), respectively] than biologic-naïve patients. Patients with previous anti-interleukin (IL)-17 exposure, rather than tumour necrosis factor-α and IL-12/23 inhibitors, had lower PASI improvements to guselkumab than biologic-naïve patients at weeks 12, 20, and 28 [OR = 0.19 (95% CI, 0.03-0.90), 0.10 (95% CI, 0.02-0.55), and 0.03 (95% CI, 0.00-0.29), respectively].ConclusionsThe effectiveness of guselkumab was compromised in a real-world setting. Delayed onset of therapeutic response was noted in heavier patients. Biologic exposure, the number of previously used biologics, and previous exposure to IL-17 inhibitors were clinical predictors of a reduced response to guselkumab. Physicians may share this information with patients to make treatment decisions.
