Efficacy of Rupatadine 5, 10 and 20 Mg in Chronic Idiopathic Urticaria
The objective of this study is to evaluate the efficacy and safety of rupatadine for the treatment of CIU symptoms.To assess the clinical efficacy of a dose ranging of rupatadine fumarate (5mg, 10mg, and 20 mg) compared with placebo for relief of CIU symptoms.

|Official Title:||A 4-Week Dose-Finding, Multicentre, Double-Blind, Randomised, Placebo-Controlled, Parallel-Group Trial to Assess the Efficacy and Safety of Different Doses of Rupatadine Compared to Placebo in the Treatment of Chronic Idiopathic Urticaria|
- · To assess the clinical efficacy of rupatadine and determine the most effective and well tolerated dose in the treatment Chronic Idiopathic Urticaria (CIU).
- · To expand the information on the safety and tolerability of rupatadine as compared to placebo.

Objectives: To evaluate the efficacy and safety of rupatadine for the treatment of CIU symptoms.To assess the clinical efficacy of a dose ranging of rupatadine fumarate (5mg, 10mg, and 20 mg) compared with placebo for relief of CIU symptoms.
Methodology: A dose-finding multicentre, double-blind, randomised, placebo-controlled, parallel–group study Number of patients (planned and analysed): 248 patients. 62 patients will be allocated to each treatment group. 283 patients were randomised and analysed.
Diagnosis and criteria for inclusion: Man or woman aged between 12 and 65. Documented history of active CIU (urticaria wheals) with or without an associated angioedema for at least three days per week over the last 6 weeks prior to Day 0 . Active CIU (score ³2 labelled as moderate pruritus) for at least 3 days (not necessarily consecutive days) in the week before inclusion with a total score of active CIU ³6 labelled as moderate pruritus for these 3 days. Results of standard laboratory biochemistry and haematology tests obtained at screening within acceptable limits as assessed by investigator. Patient who signed the informed consent form.
Test product, dose, mode of administration, batch N°: Rupatadine 5,10 and 20 mg tablets; oral dose of 1 tablet/day for 4 consecutive weeks; batch 0102 (France) and batch 0203 (Hungary, Romania and Argentina). Expiry date: 12/2003 (France) and 10/2004 (Hungary, Romania and Argentina).
Duration of treatment: Oral administration of test formulation (5, 10, 20 mg) or placebo daily, for 4 consecutive weeks.
Reference therapy: Placebo tablets, 1 tablet/day for 4 consecutive weeks. Criteria for evaluation (efficacy): Primary efficacy measure of each treatment will compare the frequency and severity of symptoms of CIU as measured by the patient in terms of change in mean pruritus score (MPS) over the 4-week treatment period.Secondary efficacy measures include change from baseline over the 4-week treatment period in the mean number of wheals (MNW) score; mean total symptoms score (MTSS), calculated as the sum of the MPS (Mean pruritus symptoms) and the MNW (Mean number of wheals) scores and the interference with sleep and daily activities due to urticaria symptoms Criteria for evaluation (safety): AEs, laboratory tests and vital signs
