About this study

Official title: Additive Effect of Brinzolamide 1%/Brimonidine 0.2% Fixed Dose Combination as Adjunctive Therapy to a Prostaglandin Analogue

The purpose of this study is to demonstrate the additive effect of brinzolamide 1%/brimonidine 0.2% (SIMBRINZA® suspension) in subjects with either open angle glaucoma or ocular hypertension who are currently on a prostaglandin analogue (PGA) monotherapy.

Read the detailed description

This study was divided into 2 sequential phases. The Screening/Eligibility Phase included one Screening Visit and two Eligibility Visits, during which subjects washed out of all other intraocular pressure (IOP)-lowering medications and dosed with TRAVATAN Z®, XALATAN®, or LUMIGAN®, 1 drop instilled in each eye once daily for 28 days. Subjects who met all inclusion/exclusion criteria were randomized at the second Eligibility Visit. The Treatment Phase consisted of two on-therapy visits (Week 2 and Week 6).

What is being measured

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

  1. Mean Diurnal Intraocular Pressure (IOP) at Week 6

    Diurnal IOP was defined as the average of the four timepoints measured (8 AM, 10 AM, 3 PM, and 5 PM). IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and reported in millimeters mercury (mmHg). One eye was chosen as the study eye and only data for the study eye were used for the analysis. A higher IOP can be a greater risk factor for developing glaucoma or glaucoma progression (leading to optic nerve damage).

    Measured: Week 6

Secondary outcomes (3)
  1. Mean Diurnal IOP Change From Baseline to Week 6

    Baseline IOP was defined as the average of the timepoint-matched IOP measurements at Eligibility 1 and Eligibility 2 Visits. Diurnal IOP change was defined as the average of the four changes from baseline (timepoints 8 AM, 10 AM, 3 PM, and 5 PM). IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and reported in millimeters mercury (mmHg). One eye was chosen as the study eye and only data for the study eye were used for the analysis. A more negative change from baseline indicates a greater improvement, i.e., a reduction of IOP.

    Measured: Baseline, Week 6

  2. Mean Diurnal IOP Percentage Change From Baseline to Week 6

    Baseline IOP was defined as the average of the timepoint-matched IOP measurements at Eligibility 1 and Eligibility 2 Visits. Diurnal IOP Percentage Change was defined as the average of the four percent changes from baseline (timepoints 8 AM, 10 AM, 3 PM, and 5 PM). IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and reported in millimeters mercury (mmHg). One eye was chosen as the study eye and only data for the study eye were used for the analysis. A more negative percent change from baseline indicates a greater amount of improvement, i.e., a reduction of IOP.

    Measured: Baseline, Week 6

  3. Mean IOP at Week 6 for Each Time Point (8 AM, 10 AM, 3 PM, 5 PM)

    IOP was assessed using Goldmann applanation tonometry and reported in mmHg. One eye was chosen as the study eye and only data for the study eye were used for the analysis. A higher IOP can be a greater risk factor for developing glaucoma or glaucoma progression (leading to optic nerve damage).

    Measured: Week 6

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Brinzolamide 1%/brimonidine 0.2% ophthalmic suspension and Prostaglandin analogue in people with Ocular Hypertension and Open Angle Glaucoma, 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 5 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 28 Jul 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. Some participants in this study may receive a placebo. 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 8 Jun 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 Diurnal Intraocular Pressure (IOP) at Week 6 (time frame: Week 6). 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 28 Jul 2015.
