Official Title: A Randomized, Double-blind, Double Dummy, Placebo Controlled, Cross-over Exploratory Trial in Healthy Male Adult Subjects: Comparison by Means of Infrared Thermography of the Anti-H1 Potency of Levocetirizine 5 mg and Cetirizine 10 mg Tablet Single Oral Dose After Nasal Histamine Provocation.

Further study details as provided by UCB Pharma:

Primary Outcome Measures:
  • To compare by means of infrared (IR) thermography the anti-histaminic potency of levocetirizine 5mg (single dose) and cetirizine 5mg (single dose) using a placebo as control following 2 nasal histamine provocations (NHP) performed respectively 10 minutes

Secondary Outcome Measures:
  • To assess and compare onset of action of levocetirizine 5 mg and cetirizine 10 mg
  • To explore predictive value of screening thermography parameters on treatment effect
  • To collect additional safety information on levocetizine

Estimated Enrollment: 60
Study Start Date: July 2004
Study Completion Date: October 2004
Primary Completion Date: October 2004 (Final data collection date for primary outcome measure)
