Remission & chronicity

Spontaneous remission
Spontaneous remission at 1 year: ~50%; at 5 years: ~65-70%; but 10-15% remain chronic beyond 5 years; remission followed by relapse common
Best-intervention remission
Omalizumab (anti-IgE): complete symptom resolution in 36-44% at 12 weeks (GLACIAL, ASTERIA trials); high-dose antihistamines (4x standard dose): 50-60% symptom control; cyclosporine for antihistamine-refractory: 50-60% response; dupilumab for CSU: 73% UAS7 ≤6 at 24 weeks (Phase 3 LIBERTY-CSU CUPID 2023)
Drug-free remission
Relapse after remission
Chronicity
Gap size
Moderate — omalizumab is transformative but not accessible as first-line; many patients on inadequate antihistamine doses or antihistamine monotherapy long-term
Primary barrier
access/practice
Barrier detail: Omalizumab (Xolair) was FDA-approved for CSU in 2014 but remains unavailable as first-line (prior authorisation requiring antihistamine failure first); many patients spend years on sedating antihistamines or systemic OCS; dupilumab (2023 Phase 3 data) adds a second biologic option

Last SoC change: 2023 — dupilumab Phase 3 LIBERTY-CSU CUPID positive (likely approval pending); 2014 omalizumab approved for CSU; cetirizine/fexofenadine as first-line since 1990s
