For some patients with atopic dermatitis (AD), topical corticosteroids (TCS), topical calcineurin inhibitors (TCI), and systemic therapies are inadequate to control disease or are associated with adverse events (AEs). Ruxolitinib cream monotherapy demonstrated anti-inflammatory and anti-pruritic effects among patients enrolled in two pivotal phase...

Background Pruritus, skin pain, and sleep disturbance are a significant burden to individuals with moderate-to-severe atopic dermatitis (AD) and negatively impact quality of life. Fit-for-purpose patient-reported outcome measures (PROMs) that assess AD-related pruritus, skin pain, and sleep disturbance are important for evaluating the effectiveness...

With newer biologics, the achievement of complete skin clearance has become an attainable treatment goal for patients with plaque psoriasis. We evaluate how improvements in Psoriasis Area and Severity Index (PASI) responses, particularly at incremental improvements approaching complete skin clearance (PASI 100), translate into improvements in healt...

Patients with psoriasis (PSO) and psoriatic arthritis (PsA) may frequently switch biologic therapies over the course of treatment because of symptom variability and individual responses. Real-world studies analyzing patient characteristics and clinical factors associated with biologic switching are limited. This longitudinal cohort study used real-...

Due to variable psoriasis symptoms, disease progression, and individual responses to therapy, patients may start, stop, or switch biologic therapies. Real-world data on the associated disease burden of patients with psoriasis who do and do not switch biologics are incomplete. This study compared disease burden among patients from the CorEvitas Psor...

Background Janus kinase inhibitors (JAKi) have the potential to alter the landscape of atopic dermatitis (AD) management dramatically, owing to promising efficacy results from phase III trials and their rapid onset of action. However, JAKi are not without risk, and their use is not appropriate for all patients with AD, making this a medication clas...

Risankizumab has demonstrated a favourable safety profile in patients with psoriatic disease (moderate-to-severe psoriasis [PsO] and psoriatic arthritis [PsA]). We evaluated the long-term safety of risankizumab in psoriatic disease. Long-term safety was evaluated by analysing data from 20 (phase 1–4) clinical trials for plaque PsO and four (phase 2...

Background Psoriasis is an immune-mediated inflammatory disease characterized by activation of IL-23–driven IL-17–producing T cell and other IL-23 receptor–positive IL-17–producing cell responses. Selective blockade of IL-23p19 with guselkumab was superior to blockade of TNF-α with adalimumab (ADA) in treating moderate-to-severe psoriasis. Objectiv...

IL-23 is a cytokine produced by myeloid cells that drives the T helper 17 pathway and plays an essential role in the pathophysiology of plaque psoriasis. IL-23 activation initiates a cascade of cytokines subsequently inducing the expression of many psoriasis-related proteins. This study aimed to better understand the underlying mechanisms driving t...
