Alcon Research Identifier:
First received: January 11, 2011
Last updated: March 8, 2013

The purpose of this study was to determine if difluprednate ophthalmic emulsion is effective in reducing the ocular symptoms of dry eye disease, as measured by a global Visual Analog Scale (VAS) discomfort score.

Condition Intervention Phase
Dry Eye Disease Drug: Difluprednate 0.05% ophthalmic emulsion Other: Difluprednate vehicle Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Multi-Center, Randomized, Double-Masked Evaluation of Anti-Inflammatory Treatment in Patients With Dry Eye

Primary Outcome Measures:
  • Mean Change From Baseline (Week 0) in Visual Analog Scale (VAS) Global Ocular Discomfort Score Over 4 Weeks [ Time Frame: Baseline, up to 4 weeks ]
    A Visual Analog Scale (VAS) was used by the subject to assess ocular discomfort, both frequency and severity, at baseline (pre-treatment) and weekly thereafter for 4 additional weeks. Each scale was 100 millimeters (mm) in length. The VAS score was calculated by measuring the length in mm from the start of the line to the intersection point of the vertical mark made by the subject. The Global Ocular Discomfort Score is a composite of the two VAS scores, ranging from 0 (very mildly) to 100 (very severely uncomfortable).

Arms Assigned Interventions
Experimental: Durezol
Difluprednate 0.05% ophthalmic emulsion, 1 drop to the study eye 2 times a day for 4 weeks, followed by 1 drop to the study eye once daily for 1 week to allow for tapering of the steroid exposure.
Drug: Difluprednate 0.05% ophthalmic emulsion
Topical ocular steroid
Other Name: DUREZOL™
Placebo Comparator: Vehicle
