To compare drug survival of ixekizumab to other IL-17 inhibitors (IL-17i) and TNF (TNFi) among patients with psoriasis (PsO) in a real-world setting. Participants included adult PsO enrolled the Corrona Psoriasis Registry who initiated ixekizumab, TNFi, or IL-17i between 16 March 2016 10 August 2019 completed ≥1 follow-up visit. Multivariable adjusted hazard ratios (HR) were calculated estimate risk for discontinuation group relative drugs. Among 1604 initiations, 552 450 602 IL-17i. Mean...

Little is known about how psoriatic disease characteristics and treatment outcomes differ geographically in the United States. Our aim was to explore real-world, geographic variations use of biologic classes within Corrona Psoriasis Registry. Patient demographics were assessed at initiation 6 months. Logistic regressions conducted evaluate odds achieving targeted for seven States regions. We examined 737 initiations among 717 patients. IL-17 inhibitors used most frequently (45%), followed by...

Summary We compared a novel 5% testosterone (T) cream (AndroForte 5, Lawley Pharmaceuticals, Australia) with 1% T gel (Testogel, Besins Healthcare, Australia). Using an open‐label crossover design, subjects were randomized to one of two treatment sequences using either the or first in 1 : ratio. Each period was 30 days 7–14 washout between them. On Days and each blood sampled at −15, −5 min, 0, 2, 4, 6, 7, 8, 9, 10, 12 16 h post study drug administration. Sixteen men established androgen...

The aim of this work is to describe real-world biologic-experienced psoriasis patients initiating ixekizumab by prior biologic therapy status and compare the effectiveness between who previously failed secukinumab those other biologics. We hypothesized that (1) clinical outcomes patient-reported would improve following a switch IXE, (2) there be no differences in responses biologics.Participants (n = 419) included adult enrolled CorEvitas Psoriasis Registry through 9/10/20 switched after...

Background: Real-world data on patients newly initiating ixekizumab is limited. Our study describes the characteristics of who initiated and other biologics for psoriasis treatment in North American dermatological practices. Materials & methods: Characteristics ascertained at registry enrollment are described via means frequencies.
