Further study details as provided by Alcon Research:

Primary Outcome Measures:
  • Change in Intraocular Pressure (IOP) at the Final Visit From Prior Beta-blocker Monotherapy (Timolol 0.5% Only) [ Time Frame: Baseline, Week 8 ] [ Designated as safety issue: No ]
    As measured at baseline and final visit with Goldmann applanation tonometry. The outcome measure was pre-specified for Timolol 0.5% only participants.

Secondary Outcome Measures:
  • Percentage of Patients With Target IOP (≤18 mmHg), Regardless of Prior Therapy [ Time Frame: Week 8 ] [ Designated as safety issue: No ]
    As measured with Goldmann applanation tonometry. The outcome measure was pre-specified for all participants.

Enrollment: 74
Study Start Date: May 2011
Study Completion Date: March 2012
Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: AZARGA
Brinzolamide 1% and timolol 0.5% fixed combination eye drops, one drop administered to the study eye(s) twice daily (8:00 am and 8:00 pm) for up to 8 weeks.
Drug: Brinzolamide 1% and timolol 0.5% fixed combination eye drops
Other Name: AZARGA®


Ages Eligible for Study:   20 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Clinical diagnosis of ocular hypertension, primary open-angle or pigment dispersion glaucoma in both eyes.
  • Must be on a stable regimen of intra-ocular pressure (IOP) lowering medication within one week of screening/baseline visit.
  • Must have an IOP of between 19 and 35 mmHg (both inclusive) in at least one eye, which would be the study eye, at screening.
  • Must be willing to discontinue the use of all other ocular hypotensive medications prior to receiving the study medication for the entire course of the study.
  • Must have best corrected visual acuity of 6/60 (20/200 Snellen, 1.0 LogMAR) or better in each eye.
  • Other protocol-defined inclusion criteria may apply.

Exclusion Criteria:

  • Known medical history of allergy, hypersensitivity, or poor tolerance to any component of the medication to be used in the study deemed clinically significant in the opinion of the principal investigator.
  • Any abnormality preventing reliable applanation tonometry in either eye.
  • Risk of visual field or visual acuity worsening as a consequence of participating in this study, in the investigator's best judgment.
  • Pregnant or lactating.
  • Participation in any other investigational study within 30 days of screening visit.
  • Other protocol-defined exclusion criteria may apply.
