Atopic dermatitis (AD) is a chronic inflammatory disease characterized by eczematous skin lesions, intense pruritus, skin pain, sleep disruption, and mental health disturbances. There remains a need for a therapeutic option that delivers durable efficacy, safety, and convenient dosing across the AD patient population. This review provides an overview of AD pathogenesis driven by T-cell imbalance and describes a novel therapeutic option targeting the OX40 receptor, a costimulatory molecule expressed specifically on activated T cells.

Many patients with moderate-to-severe AD receiving systemic therapies, including biologics and Janus kinase (JAK) inhibitors, fail to reach or maintain treatment goals due to lack of durable response or safety/tolerability issues. Rocatinlimab is a T-cell rebalancing therapy that inhibits and reduces pathogenic T cells by targeting the OX40 receptor.

AD manifestations can impact variable anatomic regions, and involvement of the head and neck, a sensitive, hard-to-treat area, can negatively impact quality of life. In this post hoc analysis, we investigated response to rocatinlimab treatment across anatomic regions, including the head and neck.

Background: Sample size re-estimation (SSR) is a method used to recalculate sample size during clinical trial conduct to address a lack of adequate information and can have a significant impact on study size, duration, resources, and cost. Few studies to date have summarized the conditions and circumstances under which SSR is applied. We therefore performed a systematic review of the literature related to SSR to better understand its application in clinical trial settings.
