Assessing the Efficacy and Tolerability of AZARGA® (Brinzolamide 1%/Timolol 0.5% Fixed Combination) as Replacement Therapy in Patients on COMBIGAN® (Brimonidine 0.2%/Timolol 0.5% Fixed Combination) Therapy in Brazil

Study Overview
=================
Brief Summary
-----------------
The purpose of this study was to assess the efficacy and tolerability of changing to AZARGA® from prior COMBIGAN® pharmacotherapy in patients with open-angle glaucoma or ocular hypertension.

Official Title
-----------------
Assessing the Efficacy and Tolerability of AZARGA® (Brinzolamide 1%/Timolol 0.5% Fixed Combination) as Replacement Therapy in Patients on Brimonidine 0.2%/Timolol 0.5% Fixed Combination Therapy (COMBIGAN®) in Brazil

Conditions
-----------------
Glaucoma

Intervention / Treatment
-----------------
* Drug: Brinzolamide/timolol maleate fixed combination


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: 18 years of age or older. Clinical diagnosis of ocular hypertension, exfoliative open-angle glaucoma, or pigment dispersion glaucoma in at least one eye (study eye). Be on a stable intraocular pressure (IOP) lowering regimen within 30 days of the Screening Visit. IOP considered safe in both eyes in such a way that should assure clinical stability of vision and optic nerve throughout the study period. Best corrected visual acuity of 6/60 (20/200 Snellen; 1.0 LogMAR) or better in each eye. IOP between 19 and 35 mmHg in at least one eye (which would be the study eye) while on brimonidine/timolol fixed combination therapy. Other protocol-defined inclusion criteria may apply. Exclusion Criteria: Presence of other primary or secondary glaucoma not listed in inclusion criteria #2. History of ocular herpes simplex. Abnormality preventing reliable applanation tonometry. Corneal dystrophies. Concurrent infectious/noninfectious conjunctivitis, keratitis, or uveitis in either eye. Blepharitis or non-clinically significant conjunctival injection is allowed. Intraocular conventional surgery or laser surgery in study eye(s) less than three months prior to the Screening Visit. Risk of visual field or visual acuity worsening as a consequence of participation in the study, in the investigator's best judgment. Progressive retinal or optic nerve disease from any cause. Use of systemic medications known to affect IOP which have not been on a stable course for 7 days prior to the Screening Visit or an anticipated change in the dosage during the course of the study. Pregnant or lactating. Other protocol-defined exclusion criteria may apply.

| --- | --- |
| Experimental: AZARGA<br>Brinzolamide/timolol maleate fixed combination, one drop self-administered in study eye(s) twice a day for 8 weeks | Drug: Brinzolamide/timolol maleate fixed combination<br>* Commercially marketed topical ocular agent for the treatment of open-angle glaucoma (OAG) or ocular hypertension.<br>* Other names: AZARGA®;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Intraocular Pressure (IOP) at 8 Weeks From Baseline (Prior Therapy). | Intraocular pressure was measured by Goldmann applanation tonometry. Data for the worse 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). | 8 weeks |
