Innovative Advancements in Atopic Dermatitis Treatment: Nektar Therapeutics at ACAAI 2025

Nektar Therapeutics, a prominent player in the biotechnology sector, has made headlines with the announcement that data from their ongoing REZOLVE-AD Phase 2b study of rezpegaldesleukin has been accepted for a late-breaking oral presentation at the American College of Allergy, Asthma & Immunology (ACAAI) 2025 Annual Scientific Meeting. This exciting event will take place in Orlando, USA, from November 6 to 10, 2025, showcasing the latest in allergy and immunology research.

Overview of the Presentation

The presentation, titled "Rezpegaldesleukin Novel Treg-Inducing Therapy Demonstrates Efficacy in Atopic Dermatitis and Asthma in Phase 2b Trial," will be presented by Dr. Jonathan Corren. Attendees can look forward to insights from the abstract ID 7005 during a distinguished session dedicated to late-breaking oral abstracts. This presentation is scheduled for Saturday, November 8, 2025, at 5:33 PM ET in Room W231. Following the live presentation, additional details will be accessible through Nektar's website, ensuring that the scientific community can engage with this groundbreaking research.

Understanding the REZOLVE-AD Phase 2b Study

The REZOLVE-AD Phase 2b study is a global clinical trial examining the effects of rezpegaldesleukin, an innovative interleukin-2 pathway agonist, in patients suffering from moderate-to-severe atopic dermatitis. As of now, the study has enrolled 393 patients who have not previously received treatments involving biologics or JAK inhibitors. Participants are randomized across multiple dose regimens of subcutaneous rezpegaldesleukin or placebo for a 16-week induction treatment. Subsequently, patients who achieve significant reduction in EASI percent scores will continue in a blinded maintenance phase for up to 52 weeks.

The primary objective is to determine the mean improvement in the EASI score, which is established after this 16-week period. Additional goals include assessing the proportion of patients meeting effective treatment benchmarks, including the Validated Investigator Global Assessment (vIGA-AD) and improvements in patient-reported outcomes like the Itch Numeric Rating Scale (NRS). Importantly, the study also explores biomarkers, providing comprehensive insights into the treatment's impact on both dermatitis and coexisting asthma, a common comorbidity.

The Potential of Rezpegaldesleukin

Rezpegaldesleukin is a potential game-changer for individuals battling autoimmune and inflammatory disorders. By focusing on the interleukin-2 receptor complex, it seeks to normalize the immune response, specifically by promoting the proliferation of regulatory T cells (Tregs). This approach targets the very issues behind autoimmune disorders, potentially allowing patients to regain immune balance and manage their symptoms more effectively.

In an important development, the U.S. Food and Drug Administration (FDA) has granted Fast Track designation to rezpegaldesleukin, not only for atopic dermatitis but also for severe alopecia areata in patients aged 12 years and older. This acknowledgment underscores the urgent need for effective treatments in these chronic conditions, and the potential for rezpegaldesleukin to fulfill that need.

Nektar Therapeutics: A Leader in Biotechnology

Founded in San Francisco, California, Nektar Therapeutics is at the forefront of developing unique therapies that aim to address the underlying causes of autoimmune and chronic inflammatory diseases. The company highlights its commitment to pioneering approaches through innovative drug candidates like rezpegaldesleukin, which is currently evaluated across various Phase 2b trials targeting atopic dermatitis, alopecia areata, and Type 1 diabetes mellitus. Nektar's robust pipeline also features promising candidates advancing in preclinical and clinical settings, reflecting its dedication to uncovering transformative treatments.

Atopic dermatitis, affecting nearly 30 million individuals in the U.S. alone, is characterized by a compromised skin barrier, leading to inflammation and adverse skin reactions. The promising data from the REZOLVE-AD study positions Nektar Therapeutics as a pivotal player in the ongoing quest for effective therapeutic solutions for this common and often debilitating condition.
