ESBA105 in Patients With Severe Dry Eye

April 18, 2013 updated by: Alcon Research

Evaluation of ESBA105 in the Persistent Relief of Ocular Discomfort in Patients With Severe Dry Eye

The purpose of this study was to evaluate the efficacy of ESBA105 over vehicle in reducing the ocular symptoms of dry eye disease, as measured by a mean global Visual Analog Scale (VAS) discomfort score.

Study Overview

Detailed Description

Following Run-In, patients qualifying for treatment were randomized 2:1 to receive ESBA105 (experimental group) or Vehicle (control group) for 4 weeks. Patients not qualifying for treatment (based on global VAS discomfort score), were discontinued from the study.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Visual Analog Scale (VAS) Global Ocular Discomfort Score, Area Under the Curve, Day 0 to Day 28
Time Frame: Up to 28 days
An electronic Visual Analog Scale (eVAS) was used by the subject to assess ocular discomfort, both frequency and severity, at Day 0 (pre-treatment) and daily thereafter for 28 days. Assessments were entered into a LogPad® (handheld electronic device). The VAS frequency score ranged from 0 (rarely) to 100 (all the time), and the VAS severity score ranged from 0 (very mildly uncomfortable) to 100 (very severely uncomfortable). The Global Ocular Discomfort Score is a composite of the frequency and severity VAS scores (0-100).
Up to 28 days
