Efficacy and Safety of Brimonidine Tartrate Ophthalmic Solution in Adult and Geriatric Participants With Ocular Redness
October 22, 2019 updated by: Bausch & Lomb Incorporated
A Single-Center, Double-Masked, Randomized, Vehicle-Controlled, Parallel-Group Study Evaluating the Efficacy and Safety of Brimonidine Tartrate Ophthalmic Solution 0.025% Used Four Times Daily in a Population of Adult and Geriatric Subjects With Ocular Redness
To compare the efficacy and safety of brimonidine tartrate ophthalmic solution 0.025% with its vehicle for the treatment of ocular redness in a population of adult and geriatric participants with ocular redness.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Brimonidine Tartrate
Participants will apply 1 drop of brimonidine tartrate ophthalmic solution 0.025% into each eye 4 times daily for up to 4 consecutive weeks.
|
Ophthalmic solution to be applied as directed.
For use as needed during the study for evaluating corneal damage.
For use as needed during the study for intraocular pressure and dilated ophthalmoscopy.
|
Placebo Comparator: Brimonidine Tartrate Vehicle
Participants will apply 1 drop of the vehicle of brimonidine tartrate ophthalmic solution into each eye 4 times daily for up to 4 consecutive weeks.
|
For use as needed during the study for evaluating corneal damage.
For use as needed during the study for intraocular pressure and dilated ophthalmoscopy.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Ocular Redness as Measured by the Investigator Using the Ora Calibra™ Ocular Hyperemia Scale
Time Frame: 0 (predose), 5, 15, 30, 60, 90, 120, 180, and 240 minutes postdose on Day 1
|
Ocular redness using the Ora Calibra Ocular Hyperemia Scale was scored by the Investigator using the following scale (allowing half unit increments): 0=None; 1.0=Mild-Slightly dilated blood vessels, color of vessels is typically pink, can be quadrantal; 2.0=Moderate-More apparent dilation of blood vessels, vessel color is more intense (redder), involves the majority of the vessel bed; 3.0=Severe-Numerous and obvious dilated blood vessels, in the absence of chemosis the color is deep red, may be less red or pink in presence of chemosis, is not quadrantic; 4.0=Extremely Severe-Large, numerous, dilated blood vessels characterized by unusually severe deep red color, regardless of grade of chemosis, which involves the entire vessel bed.
A lower score is indicative of less redness.
|
0 (predose), 5, 15, 30, 60, 90, 120, 180, and 240 minutes postdose on Day 1
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Ocular Redness as Measured by the Participant
Time Frame: Day 1 to Day 15; Day 15 to Day 29; Day 29 to Day 36
|
Ocular redness was scored daily pre-dose and post-dose on Days 1 to 29 and scored daily on Days 30 to 36 by the participant using a 0 to 4 unit scale (not allowing half unit increments).
A lower score was indicative of less redness.
The LOCF method used for this Secondary Outcome Measure was for imputing missing daily post-dose mean scores for entire days.
If ≥1 score was provided for a day, imputation was not done.
Imputation was done within the dosing period and separately within the follow-up period.
The average (mean) daily pre-dose and post-dose scores for the dosing period Day 1 to Day 15 and dosing period Day 15 to Day 29, and the average (mean) daily score for the follow-up period Day 29 to Day 36 are reported.
|
Day 1 to Day 15; Day 15 to Day 29; Day 29 to Day 36

Change From Predose Ocular Redness Score as Measured by the Investigator Using the Ora Calibra Ocular Hyperemia Scale
Time Frame: 0 (predose), 1, 360, and 480 minutes (min) postdose on Day 1 and 0 (predose), 1, and 5 min postdose on Days 15 and 29
|
Ocular redness using the Ora Calibra Ocular Hyperemia Scale was scored by the Investigator using the following scale (allowing half unit increments): 0=None; 1.0=Mild-Slightly dilated blood vessels, color of vessels is typically pink, can be quadrantal; 2.0=Moderate-More apparent dilation of blood vessels, vessel color is more intense (redder), involves the majority of the vessel bed; 3.0=Severe-Numerous and obvious dilated blood vessels, in the absence of chemosis the color is deep red, may be less red or pink in presence of chemosis, is not quadrantic; 4.0=Extremely Severe-Large, numerous, dilated blood vessels characterized by unusually severe deep red color, regardless of grade of chemosis, which involves the entire vessel bed.
A lower score is indicative of less redness.
