Abstract
BACKGROUND: Angioedema, present in some patients with chronic idiopathic/spontaneous urticaria (CIU/CSU), may have a negative effect on patient quality of life. OBJECTIVE: To describe patient-reported angioedema and its management in the pivotal omalizumab studies (ASTERIA I, ASTERIA II, GLACIAL). METHODS:Enrolled patients with CIU/CSU remained symptomatic despite treatment with histamine1 (H1)-antihistamines at licensed doses (ASTERIA I, ASTERIA II) or H1-antihistamines at up to 4 times the approved dose plus H2-antihistamines and/or a leukotriene receptor antagonist (GLACIAL). All studies administered omalizumab (75, 150, or 300 mg in ASTERIA I and ASTERIA II; 300 mg in GLACIAL) or placebo subcutaneously every 4 weeks for at least 12 weeks. Urticaria Patient Daily Diary entries were completed by patients and summarized. RESULTS: At baseline, angioedema prevalence was higher in GLACIAL (53.1%) than in ASTERIA I (47.5%) or ASTERIA II (40.7%). The mean proportion of angioedema-free days during weeks 4 to 12 was greater for patients treated with 300 mg of omalizumab than placebo in ASTERIA I (96.1% vs 88.2%, P < .001), ASTERIA II (95.5% vs 89.2%, P < .001), and GLACIAL (91.0% vs 88.7%, P = .006). Most patient-reported angioedema was managed by low-intensity interventions (doing nothing or taking medication). CONCLUSION: Treatment with 300 mg of omalizumab was efficacious in reducing patient-reported angioedema. Low-intensity interventions were generally used to manage angioedema episodes. TRIAL REGISTRATION: clinicaltrials.gov Identifiers: NCT01287117 (ASTERIA I), NCT01292473 (ASTERIA II), and NCT01264939 (GLACIAL).
