Brief Summary
This will be a Phase 3, multicenter, vehicle-controlled, double-masked, randomized study conducted at approximately 20 sites in the United States. All subjects enrolled will have dry eye disease (DED). The study will consist of Screening (Day -14) and Baseline (Day 1) visits as well as visits at Day 7, Day 14, Day 28, and Day 90 (Study Exit) for an individual duration of participation of approximately 15 weeks.

Outcome Measures
Primary Outcomes (1)
Percentage of Subjects Who Achieved Equal to or Greater Than 10 Millimeter Increase From Pre-drop at Baseline to Post-drop on Day 14 in Study Eye Unanesthetized Schirmer Score
The Schirmer test measures tear production using a filter paper placed on the lower eyelid. The amount of wetting was recorded on a scale from 0 millimeters (mm) (no tear production) to 35 mm (maximum). The test was performed at Day 1 prior to drop exposure and at Day 14 following drop exposure. An increased score represents a positive outcome. One eye (study eye) contributed data to the analysis.
Baseline (Day 1) pre-drop; Day 14 post-drop
Secondary Outcomes (11)
Least Squares Mean Change From Baseline in Global Symptom Assessment iN Dry Eye (SANDE) Score on Day 28
Baseline (Day 1); Day 28
Least Squares Mean Change From Pre-drop Baseline in Unanesthetized Schirmer Score on Post-drop Day 14 (Study Eye)
Baseline (Day 1) pre-drop; Day 14 post-drop
Percentage of Subjects Who Achieved Equal to or Greater Than 10 Millimeter Increase From Pre-drop at Baseline to Post-drop on Day 1 in Study Eye Unanesthetized Schirmer Score
Baseline (Day 1) pre-drop; Day 1 post-drop
Least Squares Mean Change From Pre-drop Baseline in Unanesthetized Schirmer Score on Post-drop Day 1 (Study Eye)
Baseline (Day 1) pre-drop; Day 1 post-drop
Percentage of Subjects Who Achieved Equal to or Greater Than 10 Millimeter Increase From Pre-drop at Baseline to Post-drop on Day 90 in Study Eye Unanesthetized Schirmer Score

Eligibility Criteria
You may qualify if:
- Signs and symptoms of dry eye disease (DED) at the Screening and Baseline visits;
- Corrected visual acuity of +0.70 logarithm Minimum angle of resolution (LogMAR) or better in both eyes at Screening and Baseline visits;
You may not qualify if:
- History or presence of any ocular disorder or condition (other than DED) in either eye that would, in the opinion of the investigator, likely interfere with the interpretation of the study results or subject safety;
- Regular use of lid hygiene within 14 days prior to the Screening visit or any planned use during the study;
- Use of artificial tears within 2 hours prior to the Screening visit or anticipated use during the study;
- Medication use as specified in the protocol;
- History or presence of significant systemic disease;
