    Abstract:
    Purpose: Real-world data comparing long-term performance of interleukin (IL)-23 and IL-17 inhibitors in psoriasis are limited. This study compared treatment persistence and remission among patients initiating guselkumab versus IL-17 inhibitors. Methods: Adults with psoriasis initiating guselkumab, secukinumab, or ixekizumab treatment (index date) were identified from Merative™ MarketScan® Research Databases (01/01/2016-10/31/2021). Persistence was defined as no index biologic supply gaps of twice the labeled maintenance dosing interval. Remission was defined using an exploratory approach as index biologic discontinuation for ≥6 months without psoriasis-related inpatient admissions and treatments. Results: There were 3516 and 6066 patients in the guselkumab versus secukinumab comparison, and 3805 and 4674 patients in guselkumab versus ixekizumab comparison. At 18 months, the guselkumab cohort demonstrated about twice the persistence rate as secukinumab (hazard ratio [HR] = 2.15; p < 0.001) and ixekizumab cohorts (HR = 1.77; p < 0.001). At 6 months after index biologic discontinuation, the guselkumab cohort was 31% and 40% more likely to achieve remission than secukinumab (rate ratio [RR] = 1.31; p < 0.001) and ixekizumab cohorts (RR = 1.40; p < 0.001). Conclusions: Guselkumab was associated with greater persistence and likelihood of remission than IL-17 inhibitors, indicating greater disease control and modification potential.
