Randomized Phase III Study to Evaluate the Efficacy and Safety of Xyzal® (Levocetirizine) vs Zyrtec® (Cetirizine) in Subjects With Dermatitis and Eczema

A Multi-centre, Double-blind, Double-dummy, Randomized, Active-controlled Phase III Study to Evaluate the Efficacy and Safety of Xyzal® 5mg od vs Zyrtec® 10mg od in Subjects Aged 15 Years and Above With Dermatitis and Eczema

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Responder Status According to Pruritus Severity Score (Response = Mild or None in Pruritus Severity Score).	A participant is a responder if the pruritus severity score is assessed as mild or none, otherwise it is a non-responder. The responder status is defined at day 14, except if the investigator assessed the subject as a responder at day 7. The Pruritus Score is in general defined as: 3 for Severe, 2 for Moderate, 1 for Mild and 0 for None.	Day 7 and 14

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in the Mean Pruritus Severity Score at Endpoint During the 14 Day Treatment Period	The Pruritus Score Scale ranges from 0 to 3 (3 for Severe, 2 for Moderate, 1 for Mild and 0 for None). Endpoint is at visit 4 on day 14 or at an earlier timepoint at study completion.	Baseline and at endpoint during the 14 day treatment period
Duration of Pruritus (Stated in Categories) at Endpoint During the 14 Day Treatment Period	Duration of pruritus was categorized as follows: 3 if > 6 hours/24hr, 2 if 1 to 6 hours/24hr, 1 if less than 1 hour/24hr, and 0 if No pruritus. The endpoint is visit 4 on day 14 or at an earlier time point at study completion.	At endpoint during the 14 day treatment period
Global Improvement at Endpoint During the 14 Day Treatment Period	Global improvement is measured on an ordered nominal scale ranging from marked improvement to exacerbation (see categories in the table). The endpoint is visit 4 on day 14 or at an earlier time point at study completion.	At endpoint during the 14 day treatment period
