A Study to Assess and Compare the Effects of 5 mg vs. 20 mg Desloratadine on the Development of Cold Urticaria Lesions - Full Text View

Sponsor:	Charite University, Berlin, Germany
Information provided by:	Charite University, Berlin, Germany
ClinicalTrials.gov Identifier:	NCT00600847

Purpose

The aim of this study is to compare cold urticaria lesions by thermography, volumetry and digital time lapse photography in ACU patients treated with placebo, 5 mg and 20 mg desloratadine. Hypothesis: The updosing of desloratadine (20 mg)is more effective in the treatment of ACU symptoms as compared to standard doses (5 mg desloratadine) and placebo.

Primary Outcome Measures:

Reduction in the development of urticaria lesions (wheal and flare) induced by TempTest challenge as assessed by digital time lapse photography, volumetry and thermography. [ Time Frame: 90 minutes ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Decrease in critical temperature thresholds and increase in critical stimulation time thresholds as assessed by standardized TempTest challenge. [ Time Frame: 15 minutes ] [ Designated as safety issue: No ]

Enrollment:	33
Study Start Date:	November 2006
Primary Completion Date:	November 2007 (Final data collection date for primary outcome measure)
