About this study

Dry eye syndrome is a highly prevalent ocular disease with an increasing incidence in the elderly population. Topically administered lubricants are the basis for treatment of this disease. However, exact information about influence on tear film thickness and corneal residence time of topical lubricants is still sparse, therefore no ideal treatment regimen has been found.

Recently a new method for assessment of tear film thickness based on ultra-high resolution optical coherence tomography (OCT) has become available. The aim of the present study is to assess the influence on tear film thickness of three different formulations of topical lubricants, in particular Thealoz Duo® Eye Drops, Optive® Eye Drops and Systane Ultra® Eye Drops in patients with moderate to severe dry eye disease. In addition, standard tests for dry eye syndrome, such as the ocular surface disease index (OSDI©), Schirmer I test, corneal fluorescein staining and determination of tear break up time (BUT) will be performed to compare the product effects.

What is being measured

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

  1. Change in tear film thickness as measured with Optical Coherence Tomography (OCT)

    Tear film thickness as measured with Optical Coherence Tomography (OCT) predose and at defined time points after the first instillation, as well as on each study day

    Measured: 10 weeks; at baseline, 10 minutes, 20 minutes, 40 minutes, 60 minutes, 120 minutes and 240 minutes after instillation of eye drops as well as 4 weeks and 8 weeks after the first instillation

Secondary outcomes (8)
  1. Tear Break Up Time (BUT)

    Measured: 10 weeks

  2. Subjective evaluation of ocular comfort with questionnaire

    Measured: 10 weeks

  3. Schirmer I test

    Measured: 10 weeks

  4. OSDI score

    Measured: 10 weeks

  5. Corneal fluorescein staining (Oxford grading scale)

    Measured: 10 weeks

  6. Conjunctival hyperemia score

    Measured: 10 weeks

  7. Efficacy assessment of eye drops by the patient with questionnaire

    Efficacy of eye drops will be performed by the patient by choosing one of the following options:

    • Very satisfactory
    • Satisfactory
    • Not very satisfactory
    • Unsatisfactory

    Measured: 10 weeks

  8. Efficacy assessment of eye drops by the investigator with questionnaire

    Efficacy of eye drops will be performed by the investigator by choosing one of the following options:

    • Very satisfactory
    • Satisfactory
    • Not very satisfactory
    • Unsatisfactory

    Measured: 10 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Thealoz Duo Eye Drops, Optive Eye Drops and Systane Ultra Eye Drops in people with Dry Eye Syndromes, run by Medical University of Vienna at 1 site in Austria.

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 7 inclusion and 12 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 20 Aug 2019. 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 Austria. 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. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Change in tear film thickness as measured with Optical Coherence Tomography (OCT) (time frame: 10 weeks; at baseline, 10 minutes, 20 minutes, 40 minutes, 60 minutes, 120 minutes and 240 minutes after instillation of eye drops as well as 4 weeks and 8 weeks after the first instillation). 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 20 Aug 2019.
