Event overview: On 24 June 2025 Nektar Therapeutics (Nasdaq: NKTR) furnished an 8-K disclosing top-line Phase 2b REZOLVE-AD results for rezpegaldesleukin in 393 moderate-to-severe atopic dermatitis (AD) patients. All three dose arms met the primary endpoint of mean EASI improvement at week 16 versus placebo (61%, 58% and 53% vs 31%; p<0.001).
Key week-16 efficacy:
- EASI-75: 42%, 46%, 34% vs 17% placebo (all p<0.05).
- vIGA-AD 0/1: 20% (high) & 26% (middle) vs 8% placebo.
- EASI-90 reached 25% (high dose; p<0.05).
- Body Surface Area improvement: 54%, 48%, 43% vs 17% placebo (p<0.001).
Mechanistic data: Blood biomarkers showed up to 6-fold expansion of regulatory T cells, with proportional decreases in Th2 cytokines (IL-19, TARC/CCL17, periostin, MDC/CCL22), supporting on-target immunomodulation.
Safety snapshot (16-week induction):
- ISRs in 69.7% of treated patients; 99.6% mild/moderate; <1% discontinuation.
- TEAEs (excluding ISRs): 60.3% drug vs 57.5% placebo.
- Serious drug-related AEs: 0.6% (2/320).
- No increased conjunctivitis, oral ulcers or infections.
Next milestones: Presentation of 16-week data at a 2025 medical congress, 52-week maintenance read-out in early 2026, and Phase 2b alopecia areata topline in Q4-2025.
Investment considerations: Meeting multiple efficacy endpoints and demonstrating dose-dependent biomarker activity materially de-risk the program and enhance partnering or financing optionality. Nonetheless, rezpegaldesleukin remains mid-stage; high ISR incidence, 5.6% treatment-related discontinuations, and the need for durable 52-week data add development and competitive risk.
