Trial Outcomes & Findings for Effect of OC000459 on Moderate to Severe Atopic Dermatitis (NCT NCT02002208)

NCT ID: NCT02002208

Last Updated: 2018-03-26

Results Overview

The EASI scoring system uses a defined process to grade the severity of the signs of eczema and the extent affected in four regions of the body: head and neck, trunk, upper extremities and lower extremities. The scale ranges from 0 to 72 and the severity strata for the EASI are as follows: 0 clear; 0.1-1.0 almost clear; 1.1-7.0 mild; 7.1-21.0 =moderate; 21.1-50.0 severe; 50.1-72.0 very severe. When assessing response to therapy a reduction of 7 or more is considered to be clinically meaningful.

Participant Flow

142 patients were randomised. One patient withdrew prior to dosing meaning that there was 141 patients in the safety set. 2 further patients withdrew prior to the first efficacy measurement which means there were 139 patients in the full analysis set.
