Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 17 years and older
- All sexes
- No healthy volunteers
- Child, Adult, Older adult
Who may be able to join
- At least 17 years of age and has full legal capacity to volunteer;
- Has read and signed an information consent letter;
- Is willing and able to follow instructions and maintain the appointment schedule;
- Is a current non-contact lens wearer.
- Has previously been diagnosed with primary open angle glaucoma and is currently being treated with a topical therapeutic agent.
- The glaucoma medication dosage and usage must have been the same for >6 months.
- Shows a minimum score of 2 (sometimes) on the SESOD questionnaire.
- Distance VA of at least 20/40 in each eye with current spectacle correction.
Who cannot join
- Is participating in any concurrent clinical or research study;
- Has any known active* ocular disease and/or infection; except primary open angle glaucoma.
- Has a systemic condition that in the opinion of the investigator may affect a study outcome variable;
- Is using any systemic or topical medications (with the exception of glaucoma medication) that in the opinion of the investigator may affect a study outcome variable;
- Has known sensitivity to the diagnostic pharmaceuticals to be used in the study;

Show all 11Show fewer
- Has undergone refractive error surgery;
- Is an employee of the Centre for Contact Lens Research;
- Has taken part in another (pharmaceutical) research study within the last 30 days;
- Is currently using artificial tears more than 3 times per day.
- For the purposes of this study, active ocular disease is defined as infection or inflammation that requires therapeutic treatment. Mild (i.e. not considered clinically relevant) lid abnormalities (blepharitis, meibomian gland dysfunction, papillae), corneal and conjunctival staining and dry eye are not considered active ocular disease. Neovascularization and corneal scars are the result of previous hypoxia, infection or inflammation and are therefore not active.

Secondary outcomes (3)
Ocular Surface Disease Index (OSDI) Score
The OSDI is a questionnaire that consists of 12 questions about ocular irritation and the effect of dry eye on vision. For every question, participants check a score between 0 and 4, where 0 equals "none of the time" and 4 equals "all of the time". OSDI scores are calculated according to: OSDI = [(sum of scores for all questions answered)*100] / [(total number of questions answered)*4]. The possible range of the OSDI score is 0 (best possible score) to 100 (worst possible score).

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Refresh Tears Lubricant Eye Drops (Allergan) in people with Glaucoma and Dry Eyes, run by University of Waterloo at 1 site in Canada.
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 8 inclusion and 11 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 5 Jun 2017. 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 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 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?
Yes. Results are posted in the registry (first posted 3 Jul 2014). 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 Staining (time frame: At baseline (dispensing visit)). The study lists 6 primary outcomes in all. 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 5 Jun 2017.
