Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are 12 years or older, weigh at least 40 kg, have chronic moderate-to-severe atopic dermatitis with higher disease activity (IGA ≥3, EASI ≥16, and ≥10% body surface area affected), and have documented inadequate response or intolerance to topical therapies.
✕Probably not a fit
Patients whose disease does not respond to Rezpegaldesleukin or who do not meet the inclusion criteria may not experience benefit.

What this trial studies
This Phase 3, randomized, double-blind trial compares Rezpegaldesleukin to placebo in participants 12 years and older with moderate-to-severe atopic dermatitis. Eligible patients have long-standing disease, a baseline IGA of 3 or higher, at least 10% body surface area involvement, and an EASI score of 16 or more, and have not adequately responded to topical therapies. The study aims to determine whether the investigational drug can improve skin symptoms over a roughly 15-month overall participation period. Locations are investigators sites operated by Nektar Therapeutics in Arizona, Arkansas, and California. The sponsor is Nektar Therapeutics, with no listed collaborators.
Why it matters
Potential benefit: If successful, participants may experience improved skin symptoms and reduced disease activity compared with placebo.
How similar studies have gone: Prior studies in this area have shown promise for similar biologic approaches in atopic dermatitis, but this exact agent and regimen require confirmation in this Phase 3 setting.

Inclusion Criteria: * Male or female patients, ≥ 12 years of age on the day of signing the informed consent form and weighing ≥ 40 kg prior to randomization at Baseline * Chronic atopic dermatitis (AD) defined as onset of AD signs and symptoms ≥ 12 months prior to Screening as determined by the Investigator through patient interview and/or review of medical history at the Screening Visit * Patients must meet the following AD severity criteria: * IGA score ≥ 3 (scale of 0 to 4) at Screening and Baseline * ≥ 10.0% of BSA involvement at Screening and Baseline * EASI ≥ 16.0 at Screening and Baseline * Are candidates for systemic therapy and have history, documented by a physician and/or the Investigator, of inadequate response to existing topical medications within 6 months preceding Screening, or history of intolerance to a topical therapy * Provide written, informed consent to participate in the study and follow the study procedures, including compliance with the use of highly effective contraceptives Exclusion Criteria: * Are currently experiencing or have a history of concomitant skin conditions other than AD, including skin infection in the area affected by the patient's AD that requires treatment with systemic antimicrobial therapy * Are currently experiencing or have a history of unstable course of AD * History of chronic idiopathic urticaria at any time or urticaria from other causes within 4 weeks prior to randomization at the Baseline Visit. * Have a history of TCS use suggestive of a high risk for topical corticosteroid (TCS) withdrawal * Have received any of the following treatments at any time before Screening: aldesleukin; investigational IL-2 analog; systemic biologic; oral JAKi; or any prior investigational agent for AD * Have a current or recent acute, active infection
