Nektar Therapeutics' Phase 2b Trial Enrollment Completes for AD

Nektar Therapeutics Achieves Milestone in Atopic Dermatitis Trial

Nektar Therapeutics (NASDAQ: NKTR) has reached a significant milestone by completing the target enrollment for its Phase 2b clinical trial known as REZOLVE-AD, involving the innovative treatment rezpegaldesleukin. This milestone is particularly encouraging for patients suffering from moderate-to-severe atopic dermatitis, a condition that affects many individuals worldwide.

The Promise of Rezpegaldesleukin

Rezpegaldesleukin is a groundbreaking interleukin-2 receptor (IL-2R) agonist designed to promote the proliferation and activation of regulatory T cells (Tregs). These Tregs play a crucial role in modulating the immune response, especially in conditions characterized by inflammation such as atopic dermatitis. Clinical data suggests that rezpegaldesleukin can effectively enhance Treg populations while also producing significant, durable improvements in skin conditions for patients.

Positive Clinical Outcomes

Multiple studies have provided promising results regarding rezpegaldesleukin’s efficacy. Patients receiving this treatment have shown rapid improvement in the efficacy measures of their skin condition, remaining stable even after the therapy was discontinued. Findings indicate that many patients maintained these positive effects for more than 36 weeks following the end of treatment. This efficacy has positioned rezpegaldesleukin as a leading candidate for addressing the needs of patients with this persistent skin condition.

Trial Overview and Patient Enrollment

The REZOLVE-AD trial involves a comprehensive assessment of patients with moderate-to-severe atopic dermatitis who have not previously engaged with biologic or JAK inhibitor treatments. The trial has enrolled a total of 396 participants, randomized across various dosing regimens of rezpegaldesleukin or a placebo, and featuring a robust 16-week treatment phase.

During this period, an emphasis was placed on monitoring improvements in the participants' Eczema Area and Severity Index (EASI) scores, which serve as a key indicator of treatment efficacy. The trial's design also includes secondary endpoints to further understand the treatment's impact on patient health, including validated global assessments and itch severity measures.

Global Reach and Recruitment Process

The recruitment for this trial spans approximately 110 clinical sites globally, with a substantial proportion of participants coming from Europe. Participation levels indicated 67% enrollment from multiple European nations, while regions such as North America and Australia made significant contributions to trial numbers. The diversity in enrollment ensures that the data collected can be reflective of a wide patient demographic.

About Atopic Dermatitis and the Need for Innovation

Atopic dermatitis, often recognized as the most common form of eczema, poses significant challenges for affected individuals, impacting daily life and emotional wellbeing. Current treatment options are limited, with many patients remaining untreated despite the availability of biologics. This gap highlights the urgent need for innovative therapies like rezpegaldesleukin, aiming to provide lasting relief for this chronic skin concern.

Nektar Therapeutics recognizes the barriers patients face and is committed to advancing therapies that can restore immune balance and improve quality of life. The goal is to not only address the symptoms but to also facilitate a holistic approach to managing atopic dermatitis through swift and effective treatments.

Future Outlook

In their recent communications, Nektar's leadership expressed gratitude towards the patients and healthcare providers who participated in the trial, contributing to an ambitious endeavor completed within just 14 months. Looking forward, Nektar Therapeutics anticipates releasing topline results from the 16-week induction phase during the second quarter of 2025, which could pave the way for new treatment avenues for those grappling with moderate-to-severe atopic dermatitis.
