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.

Condition Intervention Phase
Drug: Brinzolamide/timolol maleate fixed combination
Phase 4

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
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

Primary Outcome Measures:
  • Change in Intraocular Pressure (IOP) at 8 Weeks From Baseline (Prior Therapy). [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
    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).

Enrollment: 9
Study Start Date: March 2012
Study Completion Date: August 2012
Primary Completion Date: August 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: AZARGA
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
Commercially marketed topical ocular agent for the treatment of open-angle glaucoma (OAG) or ocular hypertension.
Other Name: AZARGA®


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

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.
