ABSTRACT
BACKGROUND:
Psoriasis is a chronic immune-mediated inflammatory skin disease that often leads to a diminished quality of life. Goals of treating patients with psoriasis have shifted with more focus on achieving near or complete clearance of the skin. Guselkumab, a fully human monoclonal antibody targeting interleukin-23, is effective in treating moderate-to-severe psoriasis.OBJECTIVE:
To describe the baseline characteristics of patients with moderate-to-severe psoriasis achieving super-response (Psoriasis Area and Severity Index [PASI] 100 response at Weeks 20 and 28) after commencing guselkumab treatment.METHODS:
Pooled data from VOYAGE 1 and VOYAGE 2 studies identified super-response; baseline demographic, disease and pharmacokinetic characteristics were compared with non-super-response. A stepwise logistic regression analysis identified which factors were potentially predictive of super-response status, with significance level of 0.1.RESULTS:
A subset of patients randomized to guselkumab comprised this post hoc analysis (n = 664); 271 patients achieved super-response vs. 393 with non-super-response. Patient age at study entry and baseline body weight (≤90 kg vs. >90 kg), PASI, and Investigator's Global Assessment (IGA) score were significant predictors of super-response status, with odds ratios (95% confidence intervals) of 0.98 (0.967-0.993; P = 0.003), 1.42 (1.026-1.977; P = 0.034), 0.97 (0.955-0.993; P = 0.007) and 0.66 (0.433-0.997; P = 0.048), respectively. More patients with super-response achieved an early response Week 2 PASI 75 (5.5% vs. 1.8%) and Week 8 PASI 100 (22.5% vs. 3.3%) vs. non-super-response. Median serum guselkumab concentrations through Week 28 were slightly greater in patients with super-response vs. non-super-response.CONCLUSION:
Guselkumab was more likely to achieve early clinical responses (complete skin clearance) in younger patients, less obese patients and patients with less severe psoriasis.
