Clinical Trial Summary

This study evaluates the use of Brimonidine tartrate nanoemulsion eye drop solution in the treatment of Dry Eye Disease (DED). Half of participants will receive Brimonidine and half will receive ophthalmic buffered saline (placebo).

Description:

Dry eye disease (DED) is a common ocular disorder involving the aberrant production and instability of tear film, which results in damage to the ocular surface and is correlated with symptoms of ocular discomfort. This study will be a randomized, placebo-controlled, double-masked, multicenter phase 3 study in the United States conducted at approximately 25 centers. Upon meeting the eligibility criteria, enrolled subjects will be randomly assigned in a 1:1 (test:control) fashion to receive either Brimonidine Nanoemulsion Eye Drops 0.20% investigational product (test) or ophthalmic buffered saline (placebo).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change From Baseline to 4 Weeks (Day 28) in Symptom Assessment in Dry Eye (SANDE) Questionnaire Score	The SANDE questionnaire is a short Visual Analog Scale (VAS) assessment that quantifies both severity and frequency of current dry eye symptoms. The SANDE is comprised of two questions, and each question employs a 100-mm horizontal linear VAS. The measurement of symptom frequency ranges from "rarely" to "all of the time", and the symptom severity from "very mild" to "very severe". Data collected from the SANDE questionnaire was calculated by multiplying the frequency score by the severity score and obtaining the square root. The result is the Overall SANDE score which ranges from 0 to 100 with 100 being the maximal amount of dry eye symptoms and 0 being the minimal amount of dry eye symptoms.	Baseline, 4 weeks (Day 28)
Primary	Change From Baseline to 4 Weeks (Day 28) in Lissamine Green Conjunctival Staining Scores	Conjunctival staining with Lissamine Green dye (1%; LG) staining in each eye was conducted using the slit lamp. A single drop of 1% Lissamine Green dye was applied to the inferior conjunctival fornix of both eyes. The conjunctivae was examined with the slit lamp at ×10 magnification, using a neutral-density filter. The conjunctiva was graded for each eye from 0 to 3 based on the density of punctate staining in the nasal-bulbar and temporal-bulbar zones. Total scores ranged from 0 (no staining) to 6 (most severe staining) with a lower score representing a more desirable outcome.	Baseline, 4 Weeks (Day 28)
Secondary	Change From Baseline to 2 Weeks (Day 14) in SANDE Score	The SANDE questionnaire is a short Visual Analog Scale (VAS) assessment that quantifies both severity and frequency of current dry eye symptoms. The SANDE is comprised of two questions, and each question employs a 100-mm horizontal linear VAS. The measurement of symptom frequency ranges from "rarely" to "all of the time", and the symptom severity from "very mild" to "very severe". Data collected from the SANDE questionnaire was calculated by multiplying the frequency score by the severity score and obtaining the square root. The result is the Overall SANDE score which ranges from 0 to 100 with 100 being the maximal amount of dry eye symptoms and 0 being the minimal amount of dry eye symptoms.	Baseline, 2 weeks (Day 14)
Secondary	Change From Baseline to 2 Weeks (Day 14) in Lissamine Green Conjunctival Staining Scores	Conjunctival staining with Lissamine Green dye (1%; LG) staining in each eye was conducted using the slit lamp.
