Executive Commentary
"This year continues to be a transformative year for Nektar as we advance our lead program, rezpegaldesleukin, into Phase 3 clinical trials. We initiated the first Phase 3 ZENITH AD trials in atopic dermatitis in July, and we plan to start a single registrational Phase 3 study in alopecia areata in early 2027. Our Phase 3 program establishes a clear path to the first BLA submission for rezpegaldesleukin in 2029."
Howard W. Robin, President and Chief Executive Officer
"Everything we have learned about rezpegaldesleukin from the data points to a consistent and differentiated clinical profile, meaningful efficacy, a favorable safety profile with dosing as infrequent as once a quarter, and responses that continue to deepen over time. Our Phase 3 studies are designed to support a potential label that captures both treatment naive and experienced patients, spanning first line through later lines of therapy."

Strategic Positioning
1. Differentiated Mechanism of Action Targeting Regulatory T Cells
Rezpegaldesleukin (REZPEG) operates by stimulating regulatory T cells to restore immune balance upstream of multiple inflammatory pathways, contrasting with existing therapies that block single downstream mediators like IL-13. This novel approach offers potential for durable responses across several autoimmune diseases, including atopic dermatitis and alopecia areata, with ongoing evaluation in type 1 diabetes.
2. Robust Phase 3 Clinical Program for Atopic Dermatitis
The global ZENITH AD program comprises three randomized, placebo-controlled trials enrolling biologic and JAK inhibitor naive patients as well as treatment-experienced cohorts. The studies feature a 24-week induction followed by a 28-week maintenance period with monthly and quarterly dosing arms, designed to support broad label claims including first- and later-line use. Secondary endpoints include patient-reported outcomes and assessments of comorbid asthma and allergic rhinitis, reflecting REZPEG’s potential to address multiple inflammatory manifestations.
3. Planned Registrational Study in Alopecia Areata
Following FDA alignment, Nektar will initiate a single Phase 3 trial in early 2027 enrolling 850 patients with severe alopecia areata, including both treatment naive and experienced individuals. The primary endpoint is achieving 80% or more scalp hair coverage at Week 52. This study aims to complement the atopic dermatitis program and expand REZPEG’s commercial footprint in a market with significant unmet need and safety concerns around existing JAK inhibitors.
4. Strong Financial Position Supporting Aggressive Development
The company’s $1 billion-plus cash and investments balance, bolstered by a recent public offering, provides a secure runway through mid-2028, covering costly Phase 3 trials and manufacturing scale-up. This financial strength enables focused investment in late-stage clinical execution and pipeline expansion without near-term capital constraints.
5. Market Research Validates Physician Enthusiasm and Commercial Potential
Extensive surveys of over 150 high-volume prescribers and key opinion leaders in the US and Europe reveal strong physician interest in REZPEG’s novel mechanism, favorable safety profile, and convenient dosing schedules. Physicians indicated willingness to prescribe across first, second, and third lines of therapy, highlighting the drug’s potential to capture significant market share in a large and growing atopic dermatitis market projected to reach $35 billion by 2033.
