About this study

Official title: Prospective, Randomized, Single-Center Study to Evaluate 24-hour Intraocular Pressure Control With Brinzolamide 1%/Brimonidine 0.2% Fixed Dose Combination Therapy

The purpose of this study is to evaluate intraocular pressure (IOP) over a 24-hour period using Simbrinza™ topical ophthalmic suspension.

What is being measured

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

  1. Mean Nocturnal IOP at Week 4

    Nocturnal IOP (fluid pressure inside the eye) is the mean of the nocturnal time points assessed (10 PM to 6 AM). IOP was measured with a calibrated applanation tonometer in millimeters of mercury (mmHg). One eye from each subject was chosen as the study eye and only data for the study eye were used for the efficacy analysis. A higher IOP can be a greater risk factor for developing glaucoma or glaucoma progression (leading to optic nerve damage).

    Measured: Week 4: 10PM, 12AM, 2AM, 4AM, 6AM

Secondary outcomes (2)
  1. Mean Diurnal IOP at Week 4

    Diurnal IOP (fluid pressure inside the eye) is the mean of the diurnal time points assessed (8 AM to 8 PM). IOP was measured with a calibrated applanation tonometer in millimeters of mercury (mmHg). One eye from each subject was chosen as the study eye and only data for the study eye were used for the efficacy analysis. A higher IOP can be a greater risk factor for developing glaucoma or glaucoma progression (leading to optic nerve damage).

    Measured: Week 4: 8AM, 10AM, 12PM, 2PM, 4PM, 6PM, 8PM

  2. Mean 24-hour IOP at Week 4

    24-hour IOP (fluid pressure inside the eye) is the mean of all the time points assessed (8 AM to 6 AM). IOP was measured with a calibrated applanation tonometer in millimeters of mercury (mmHg). One eye from each subject was chosen as the study eye and only data for the study eye were used for the efficacy analysis. A higher IOP can be a greater risk factor for developing glaucoma or glaucoma progression (leading to optic nerve damage).

    Measured: Week 4: 8AM, 10AM, 12PM, 2PM, 4PM, 6PM, 8PM, 10PM, 12AM, 2AM, 4AM, 6AM

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Brinzolamide 1%/Brimonidine 0.2% ophthalmic suspension and Timolol Maleate 0.5% in people with Open-Angle Glaucoma and Ocular Hypertension, run by Alcon Research.

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 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 13 Apr 2015. Status can change between updates, so confirm with the study contact before making plans.

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 13 Apr 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?

Mean Nocturnal IOP at Week 4 (time frame: Week 4: 10PM, 12AM, 2AM, 4AM, 6AM). 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 13 Apr 2015.
