Trial Outcomes & Findings for Safety and Efficacy of Brinzolamide/Brimonidine Fixed Combination (NCT NCT00961649)

NCT ID: NCT00961649

Last Updated: 2013-07-04

Results Overview

The study drug was instilled at 8 AM and +7 hours relative to the 8 AM dosing (approximately 15 minutes after conducting the IOP measurements). Intraocular pressure was measured by Goldmann applanation tonometry. One eye from each patient was chosen as the study eye and only data for the study 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). Intent-to-Treat (ITT) analysis data set was pre-specified for the comparison of Brinz/Brim to its individual components (Brinz and Brim).

PRIMARY outcome

Timeframe: Baseline, Week 6

Population: ITT: All subjects who received study drug and had at least 1 scheduled on-therapy study visit.

Intraocular pressure was measured by Goldmann applanation tonometry. One eye from each patient was chosen as the study eye and only data for the study eye were used for the efficacy analysis.

PRIMARY outcome

Timeframe: Baseline, Week 6

Population: PP: All subjects who received study drug, satisfied inclusion/exclusion criteria, and had at least 1 scheduled on-therapy visit. Individual subject visits or data points were excluded if protocol criteria were violated at a subset of the subject's visits and the violations, in the opinion of the Medical Monitor, did not invalidate remaining visits.

The study drug was instilled at 8 AM and +7 hours relative to the 8 AM dosing (approximately 15 minutes after conducting the IOP measurements). Intraocular pressure was measured by Goldmann applanation tonometry. One eye from each patient was chosen as the study eye and only data for the study 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). Per-Protocol (PP) analysis data set was pre-specified for the comparison of Brinz/Brim to Brinz+Brim.
