About this trial
This is an interventional treatment trial for Open-Angle Glaucoma focused on measuring Open-Angle Glaucoma, Ocular Hypertension, Simbrinza™, Intraocular Pressure
Eligibility Criteria
Inclusion Criteria:
- Clinical diagnosis of either open-angle glaucoma or ocular hypertension in both eyes.
- Willing and able to attend all study-related visits and be housed overnight at clinical site for the study assessments.
- Must sign an Informed Consent form.
- Other protocol-specified inclusion criteria may apply.
Exclusion Criteria:
- Women of childbearing potential if pregnant, breastfeeding, or not using adequate birth control.
- Severe central visual field loss in either eye.
- Chronic, recurrent or severe inflammatory eye disease.
- Ocular trauma or ocular surgery within the past 6 months.
- Ocular infection or ocular inflammation within the past 3 months.
- Clinically significant or progressive retinal disease.
- Other ocular pathology, including severe dry eye, that may in the opinion of the investigator preclude the administration of study medication.
- Any other conditions including severe illness which would make the patient, in the opinion of the Investigator, unsuitable for the study.
- Any medical condition that would preclude the safe administration of a topical beta-blocker.
- Cannot safely discontinue all glucocorticoids administered by any route.
- Other protocol-specified exclusion criteria may apply.

SIMBRINZA™
Timolol Maleate 0.5%
Arm Description
Brinzolamide 1%/Brimonidine 0.2% ophthalmic suspension, 1 drop 3 times a day (8AM, 3PM, 10PM) in each eye for 4 weeks
Timolol Maleate 0.5%, 1 drop twice a day (8AM, 8PM) in each eye for 4 weeks
Outcomes
Primary Outcome Measures
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).
Secondary Outcome Measures
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).
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).

Brief Summary
The purpose of this study is to evaluate intraocular pressure (IOP) over a 24-hour period using Simbrinza™ topical ophthalmic suspension.
Detailed Description
This study consisted of two phases, a Screening/Eligibility Phase and a Treatment Phase. Both phases required the patient to complete an overnight stay.
