What is being measured

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

  1. Ocular Surface Disease Index© (OSDI) Score Using a 5-Point Scale

    The OSDI© is a 12-question survey for patients to document their dry eye disease symptoms. Each question is rated on a 5-point scale (0=none of the time and 4 = all of the time). The scores are totaled over the 12 questions and normalized/converted to a score of 0-100 (0=no disability and 100=complete disability).

    Measured: Day 90

Secondary outcomes (4)
  1. Change From Baseline in Corneal Staining in the Worse Eye

    The cornea is the transparent front part of the eye which covers the iris and pupil. Corneal staining in the worse eye following administration of fluorescein dye in the eye is graded using a 6-point scale (0=no staining, 5=severe staining) over 5 areas of the clear central part of the eye for a minimum score of 0 and maximum score of 25. The higher the grade score, the worse the dry eye condition. A negative change from baseline represents a decrease in corneal staining (improvement) and a positive change from baseline represents an increase in corneal staining (worsening).

    Measured: Baseline, Day 90

  2. Change From Baseline in Tear Break-up Time (TBUT) in the Worse Eye

    TBUT is the time required for dry spots to appear on the surface of the eye after blinking in the worse eye. The longer it takes, the more stable the tear film. A short TBUT is a sign of poor tear film. A positive number change from baseline indicates an increase in TBUT (improvement) and a negative number change from baseline indicates a decrease in TBUT (worsening).

    Measured: Baseline, Day 90

  3. Change From Baseline in the Schirmer Test in the Worse Eye

    The Schirmer's Test measures the rate of the secretion of tears produced by the eye over 5 minutes in the worse eye. The results indicate the presence of dry eye (Normal = greater than or equal to 10 millimeters (mm) of tears, Dry Eye = less than 10 mm of tears). The smaller the number, the more severe the dry eye. A positive number change from baseline indicates an increase in tears (improvement) and a negative number change from baseline indicates a decrease in tears (worsening).

    Measured: Baseline, Day 90

  4. Change From Baseline in Uncorrected Visual Acuity in the Worse Eye

    Uncorrected visual acuity in the worse eye is measured using an eye chart and is reported as the number of letters read correctly (ranging from 0 to 100 letters) without corrective lenses. The lower the number of letters read correctly on the eye chart, the worse the vision (or visual acuity). A positive number change from baseline in the number of letters read correctly indicates an improvement and a negative number change from baseline indicates a worsening.

    Measured: Baseline, Day 90

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing carboxymethylcellulose sodium based new eye drop formulation and carboxymethylcellulose sodium based eye drops in people with Bilateral LASIK Surgery, run by Allergan at 2 sites in 2 countries.

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 1 inclusion and 5 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 16 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Australia, Canada. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 5 Oct 2015). 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?

Ocular Surface Disease Index© (OSDI) Score Using a 5-Point Scale (time frame: Day 90). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01886690, which also lists 1 linked publication.

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 16 Apr 2019.
