简要总结
Objective: To compare the efficacy of desloratadine 5mg (Denosin®) and levocetirizine 5mg (Xyzal®) once daily in the treatment of patients with CIU over 6 weeks.
Trial design: Randomized, Double-Blind, Active-Controlled, Parallel-Group Study.
Primary end point: To evaluate the change in average AM/PM reflective pruritus score from baseline recorded in the subjects' diaries during the first two weeks of the treatment.
Secondary Objectives: To assess the efficacy and safety of desloratadine 5mg (Denosin®) and levocetirizine 5mg (Xyzal®) once daily in the treatment of subjects with CIU over 6 weeks.

- •The subject ≥ 12 years old.
- •The subject with documented signs and symptoms of CIU for 6 weeks or more.
- •The subject has to have a CIU flare for 3 weeks or more before screening, with urticarial lesions visible 3 days or more per week.
- •The overall severities of CIU have to be at least mild to moderate at screening and baseline, subjects have to have at least mild to moderate pruritus, hives have to be apparent at screening, and subjects have intention to treatment.
排除标准
- •The subject has received any histamine, corticosteroids, ketotifene, systemic antibiotics, nedocromil, sodium cromoglycate or thyroxin drug within 7 days preceding randomization.
- •The subject has received any other investigational drug within one month preceding randomization.

- •The subject has previous allergy or allergies of desloratadine or levocetirizine.
- •The subject need for long-term corticosteroids treatment (including inhaled, oral and topical dosage).
- •The subject has autoimmune diseases.
- •The subject's urticaria is physical urticaria, cholinergic urticaria or angioedema.
- •The subject is in the situation of pregnancy or breastfeeding.
- •The subject has liver dysfunction (AST ≧ 3 times normal range; ALT ≧ 3 times normal range ) or renal dysfunction (Creatinine ≧ 3.0mg/dl ).

结局指标
主要结局
To evaluate the change in average AM/PM reflective pruritus score from baseline recorded in the patient diaries during the first two weeks of treatment
次要结局
- To evaluate the change in average AM/PM reflective pruritus score from baseline recorded in the subjects' diaries over the 6 weeks.
- To evaluate the reflective average AM/PM scores for number of hives, size of largest hive, and total symptom score (sum of pruritus, number of hives, and size of largest hive scores).
- Average individual AM/PM instantaneous scores for pruritus, number of hives, and size of largest hive are also evaluated.
- AM instantaneous scores for pruritus, number of hives, and size of largest hive are also evaluated.
- PM instantaneous scores for pruritus, number of hives, and size of largest hive are also evaluated.
- PM reflective scores for pruritus, number of hives, and size of largest hive are also evaluated.
- The interference with sleep (AM reflective), and interference with daily activities (PM reflective) are other secondary efficacy outcomes.
