November 13, 2018 updated by: Alcon Research

Additive Effect of Twice Daily Brinzolamide 1%/Brimonidine 0.2% Fixed Dose Combination as an Adjunctive Therapy to a Prostaglandin Analogue

The purpose of this study is to evaluate the additive intraocular pressure (IOP) lowering effect of brinzolamide 1%/brimonidine 0.2% (dosed twice per day (BID)) when added to a prostaglandin analogue (PGA) in subjects with open-angle glaucoma or ocular hypertension.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Diagnosis of either open-angle glaucoma or ocular hypertension;
  • Must sign an informed consent form;
  • Mean IOP measurements at both the Eligibility 1 and 2 visits, in at least 1 eye (the same eye[s]) ≥ 19 and < 32 mmHg at 09:00.
  • Willing and able to attend all study visits;
  • Other protocol-specified inclusion criteria may apply.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mean Change From Baseline (on PGA) in Diurnal IOP (Mean of 09:00 and 11:00 Time Points) at Week 6
Time Frame: Baseline, Week 6
IOP (fluid pressure inside the eye) was measured using Goldmann applanation tonometry and averaged over the 09:00 AM and 11:00 AM time points. A more negative change from baseline indicates a greater improvement, i.e., a reduction of IOP. One eye (study eye) contributed to the analysis.
Baseline, Week 6

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Mean Diurnal IOP at Week 6
Time Frame: Week 6
IOP (fluid pressure inside the eye) was measured using Goldmann applanation tonometry and averaged over the 09:00 AM and 11:00 AM time points. A higher IOP can be a greater risk factor for developing glaucoma or glaucoma progression (leading to optic nerve damage). One eye (study eye) contributed to the analysis.
Week 6
Mean Percentage Change From Baseline in Diurnal IOP at Week 6
Time Frame: Baseline, Week 6
IOP (fluid pressure inside the eye) was measured using Goldmann applanation tonometry and averaged over the 09:00 AM and 11:00 AM time points. A more negative percent change from baseline indicates a greater improvement, i.e., a reduction of IOP. One eye (study eye) contributed to the analysis.
Baseline, Week 6
Mean Change From Baseline in IOP at 11:00 at Week 6
Time Frame: Baseline, Week 6
IOP (fluid pressure inside the eye) was measured using Goldmann applanation tonometry at 11:00 AM. A more negative change from baseline indicates a greater improvement, i.e., a reduction of IOP. One eye (study eye) contributed to the analysis.
Baseline, Week 6
Mean Percentage Change From Baseline in IOP at 11:00 at Week 6
Time Frame: Baseline, Week 6
IOP (fluid pressure inside the eye) was measured using Goldmann applanation tonometry at 11:00 AM. A more negative percent change from baseline indicates a greater improvement, i.e., a reduction of IOP. One eye (study eye) contributed to the analysis.
Baseline, Week 6
Mean Change From Baseline in IOP at 09:00 at Week 6
Time Frame: Baseline, Week 6
IOP (fluid pressure inside the eye) was measured using Goldmann applanation tonometry at 09:00 AM. Baseline is defined as the average of the 9:00 hour values at both Eligibility visits. A more negative change from baseline indicates a greater improvement, i.e., a reduction of IOP. One eye (study eye) contributed to the analysis.
Baseline, Week 6
Mean Percentage Change From Baseline at 09:00 at Week 6
Time Frame: Baseline, Week 6
