Ocular Hypertension Clinical Trial
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.

Eligibility |
Inclusion Criteria: - Diagnosis of open angle glaucoma (including open-angle glaucoma with pseudoexfoliation or pigment dispersion) or ocular hypertension; - Mean intraocular pressure (IOP) measurements in at least 1 eye (study eye) of = 21 mmHg and <32 mmHg at 2 consecutive visits (Eligibility 1 and Eligibility 2); - Previously prescribed TRAVATAN Z® 0.004%, XALATAN® 0.005%, or LUMIGAN® 0.01% monotherapy for at least 28 days prior to the Screening Visit; - Able to understand and sign Informed Consent Document; - Other protocol-defined inclusion criteria may apply. Exclusion Criteria: - Women of childbearing potential who are pregnant, breastfeeding, or do not agree to use an adequate birth control method throughout the study; - Any form of glaucoma other than open angle glaucoma or ocular hypertension; - Severe central visual field loss; - Chronic, recurrent, or severe inflammatory eye disease; - Ocular trauma within the past 6 months; - Ocular infection or ocular inflammation within the past 3 months; - Best-corrected visual acuity score worse than approximately 20/80 Snellen; - Eye surgery within the past 6 months; - Any condition, including severe illness, which would make the subject unsuitable for the study in the opinion of the Investigator; - Use of any additional topical or systemic ocular hypertensive medication during the study; - Patients who, in the opinion of the Investigator, cannot discontinue all IOP-lowering ocular medication(s) per the appropriate washout schedule prior to Eligibility 1 Visit; - Other protocol-defined exclusion criteria may apply. |

Primary | 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). | Week 6 | No |
Secondary | 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. | Baseline, Week 6 | No |
Secondary | 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. | Baseline, Week 6 | No |
Secondary | 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). | Week 6 | No |
