Trial summary

Although Benzalkonium chloride (BAC) has been used as a preservative for many years, many studies have demonstrated that prolonged use of topical ocular medications preserved with BAC may exacerbate sequelae associated with ocular surface disease. Read more about this study

About this study

Official title: Dry Eye and Irritation Comparison of Latanoprost 0.005% With the Preservative Benzalkonium Chloride (BAC) Vs Travoprost 0.004% Without BAC

Although Benzalkonium chloride (BAC) has been used as a preservative for many years, many studies have demonstrated that prolonged use of topical ocular medications preserved with BAC may exacerbate sequelae associated with ocular surface disease. These effects could lead to the induction of subclinical inflammation,1 reduction of corneal epithelial barrier function, 2, 3 destabilization of the tear film, 4 cataract formation, 5 and an overall higher incidence of patient complaints of dryness and irritation. 4-6 This study will compare the efficacy of travoprost 0.004% without benzalkonium chloride (BAC) to that of the marketed formulation of latanoprost 0.005%with BAC in patients with dryness and irritation and open-angle glaucoma or ocular hypertension. A double blind comparison will be used to assess whether those two different formulations will affect the tear breakup times, corneal staining, and baseline tear secretion tests in patients that are already taking latanoprost regularly with complaints of dryness and irritation. Patients included in the study will be given two bottles, one labeled for their right eye and the other for their left eye. Each pair of bottles will be identical in appearance and randomized with either latanoprost or travoprost and each pair will be assigned a number to aid in future analysis of the final results.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Travaprost without BAC (Travatan Z)Drug

    A double blind comparison was used to assess whether Xalatan or TrvatanZ affects the tear breakup times, corneal staining, and baseline tear secretion tests in patients that are already taking latanoprost regularly with complaints of dryness and irritation. Patients included in the study will be given two bottles, one labeled for their right eye and the other for their left eye. Each pair of bottles will be identical in appearance and randomized with either latanoprost or travoprost and each pair will be assigned a number to aid in future analysis of the final results. One Drop from both bottles will be dispensed in the respective eye once a day.

What is being measured

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

  1. Routine eye exams in addition to Ocular Surface Disease Index (OSDI) surveys at the beginning and end of the study. Patients will also be asked to rate their extent of dryness and irritation of either eye on a scale of 1-10 at each visit.

    Measured: Each patient will be followed every 3-4 weeks for 3 months

Questions about this trial

What is this clinical trial studying?

An observational study of Ocular Dryness and Ocular Irritation, run by United States Air Force 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 4 inclusion and 14 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 Dec 2008. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

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?

Routine eye exams in addition to Ocular Surface Disease Index (OSDI) surveys at the beginning and end of the study. Patients will also be asked to rate their extent of dryness and irritation of either eye on a scale of 1-10 at each visit. (time frame: Each patient will be followed every 3-4 weeks for 3 months). 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 Dec 2008.
