- •Have an overall condition of CIU that was at least of "moderate" severity (minimum score of 2) at both Screening and Baseline Visits.
- •Have at least a moderately severe pruritus score (minimum score of 2) and hives (minimum score of 1) present at Screening.
- •Have, at Baseline, a total pruritus score of 14 or greater for the sum of AM and PM (reflective) diary scores for the 3 days prior to Baseline and the AM diary score on Day
- •Understand and be able to adhere to the dosing and visit schedules, and agree to assess and record their symptom severity scores, medication times,concomitant medications, and adverse events accurately and consistently in a daily diary.
- •Be in general good health and free of any clinically significant disease (other than CIU) that would have interfered with study evaluations.
- •If female and of childbearing potential, have had a negative urine (hCG) pregnancy test at the time of Baseline (Visit 2).
