Efficacy of guselkumab versus secukinumab in subpopulations of patients with moderate-to-severe plaque psoriasis: results from the ECLIPSE study

Purpose Guselkumab, an interleukin (IL)-23 inhibitor, effectively treats moderate-to-severe plaque psoriasis. Materials and methods ECLIPSE, was a Phase 3, multicenter, 56-week, double-blinded, active-comparator study of guselkumab vs. secukinumab (IL-17A inhibitor) in patients with moderate-to-severe psoriasis. Patients were treated with guselkumab 100 mg (n = 534) or secukinumab 300 mg (n = 514) through week 44. Efficacy (at least a 90% and 100% improvement from baseline in Psoriasis Area and Severity Index [PASI 90 and PASI 100], Investigator's Global Assessment [IGA] 0/1, and IGA 0) was analyzed across subpopulations defined by baseline: age ( Results Overall, 1048 patients were randomized. At week 48, numerically greater proportions of patients achieved PASI 90, PASI 100, IGA 0/1, and IGA 0 with guselkumab vs. secukinumab regardless of baseline age, body weight, BMI, disease severity, body region, and prior medication. The largest differences were in patients ≥65 years old and patients weighing >100 kg. Conclusions Guselkumab treatment provided greater efficacy vs. secukinumab at week 48 in most subpopulations of patients with psoriasis.
