| Main Objective: Primary Objective •To evaluate the safety of omalizumab compared with placebo in patients with refractory chronic idiopathic urticaria (CIU) receiving concomitant therapy including H1 antihistamines at increased doses (up to four times the approved dose), H2 blockers, and/or leukotriene receptor antagonist (LTRAs) ;Secondary Objective: Secondary Objectives •To evaluate the efficacy of omalizumab compared with placebo in patients with refractory CIU receiving concomitant therapy including H1 antihistamines at increased doses (up to four times the approved dose), H2 blockers, and/or LTRAs •To evaluate onset of clinical effect of omalizumab therapy in CIU receiving concomitant therapy including H1 antihistamines at increased doses (up to four times the approved dose), H2 blockers, and/or LTRAs •To evaluate the quality-of-life benefit of omalizumab therapy in patients with refractory CIU receiving concomitant therapy including H1 antihistamines at increased doses (up to four times the approved dose), H2 blockers, and/or LTRAs ;Primary end point(s): The primary objective of this study is to evaluate the safety of omalizumab compared with placebo in patients with refractory CIU receiving concomitant therapy including H1 antihistamines at increased doses (up to four times the approved dose), H2 blockers, and/or LTRAs. The safety of omalizumab will be assessed using the following safety outcome measures: • Incidence and severity of adverse events and serious adverse events • Changes in vital signs • Clinical laboratory evaluations • ATA evaluation at the end of the follow-up period | — |
