Clinical Details

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

Study design: Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Change in Intraocular Pressure (IOP) at 8 Weeks From Baseline (Prior Therapy).


Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.


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


- 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.
