About this study

Official title: A Multi-Center, Randomized, Double-Masked Evaluation of Anti-Inflammatory Treatment in Patients With Dry Eye

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mean Change From Baseline (Week 0) in Visual Analog Scale (VAS) Global Ocular Discomfort Score Over 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).

    Measured: Baseline, up to 4 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Difluprednate 0.05% ophthalmic emulsion in people with Dry Eye Disease, run by Alcon Research at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Mar 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 11 Mar 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

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). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Mar 2013.
