Safety and Efficacy of KPI-121 in Subjects With DED

Study Overview
=================
Brief Summary
-----------------
The primary purpose of this study is to determine the efficacy and safety of KPI-121 0.25% ophthalmic suspension compared to vehicle (placebo) in subjects who have a documented clinical diagnosis of dry eye disease. The product will be studied over 14 days, with 1-2 drops instilled in each eye four times daily (QID).

Detailed Description
-----------------
This is a Phase 3, multi-center, double-masked, randomized, vehicle-controlled, parallel-group study designed to evaluate the safety and efficacy of KPI-121 0.25% ophthalmic suspension versus vehicle in subjects with dry eye disease.

* Drug: Vehicle


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Have a documented clinical diagnosis of dry eye disease in both eyes Exclusion Criteria: Known hypersensitivity or contraindication to the investigational product(s) or components History of glaucoma, IOP>21 mmHg at the screening or randomization visits, or being treated for glaucoma in either eye. Diagnosis of: ongoing ocular infection; severe/serious ocular condition that in judgment of Investigator could confound study assessments or limit compliance; or have been exposed to an investigational drug within 30 days prior to screening. In the opinion of the Investigator or study coordinator, be unwilling or unable to comply with study protocol or unable to successfully instill eye drops.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Baseline/Visit 2 (Day 1) in Ocular Discomfort Severity at Visit 4 (Day 15) | Comparison of mean ocular discomfort severity between the KPI-121 0.25% ophthalmic suspension group and the vehicle group using a 0-100 visual analog grading scale where 0 was better and 100 was worse. | Baseline/Visit 2 (Day 1) and to Visit 4 (Day 15) | 
| Change From Baseline/Visit 2 (Day 1) Ocular Discomfort Severity at Visit 4 (Day 15) in the Subgroup of Participants With More Severe Ocular Discomfort | Comparison of mean ocular discomfort severity between the KPI-121 0.25% ophthalmic suspension group and the vehicle group using a 0-100 visual analog grading scale where 0 was better and 100 was worse, in a sub-group of participants with more severe ocular discomfort at baseline. | Baseline/Visit 2 (Day 1) and to Visit 4 (Day 15) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Baseline/Visit 2 (Day 1) in Bulbar Conjunctival Hyperemia at Visit 4 (Day 15) | Comparison of mean bulbar conjunctival hyperemia between the KPI-121 0.25% ophthalmic suspension group and the vehicle group using a 0-4 grading scale. The grading scale was based on the Cornea and Contact Lens Research Unit Grading Scale where 0 = none, 1 = very slight, 2 = slight, 3 = moderate and 4 = severe. | Baseline/Visit 2 (Day 1) and to Visit 4 (Day 15) | 
| Change in Conjunctival Hyperemia Scores at Visit 4 (Day 15) by Alternate Assessor | Comparison of mean bulbar conjunctival hyperemia between the KPI-121 0.25% ophthalmic suspension group and the vehicle group using a 0-4 grading scale. The grading scale was based on the Cornea and Contact Lens Research Unit Grading Scale where 0 = none, 1 = very slight, 2 = slight, 3 = moderate and 4 = severe. | Baseline/Visit 2 (Day 1) and to Visit 4 (Day 15) | 
| Change From Baseline/Visit 2 (Day 1) in Ocular Discomfort Severity at Visit 3 (Day 8) | Comparison of mean ocular discomfort severity between the KPI-121 0.25% ophthalmic suspension group and the vehicle group using a 0-100 visual analog grading scale where 0 was better and 100 was worse. | Baseline/Visit 2 (Day 1) to Visit 3 (Day 8) | 
| Change From Baseline/Visit 2 (Day 1) in Corneal Fluorescein Staining Score at Visit 4 (Day 15) | Comparison of mean corneal fluorescein staining between the KPI-121 0.25% ophthalmic suspension group and the vehicle group using methods developed by the National Eye Institute (NEI) Dry Eye Workshop in evaluating 5 regions of the cornea (superior, inferior, nasal, temporal and central) using a 0-3 grading scale, where 0 = no visible staining, 1 = Mild, 2 = moderate and 3 = severe. | Baseline/Visit 2 (Day 1) to Visit 4 (Day 15) | 
| Change From Baseline/Visit 2 (Day 1) in Ocular Discomfort Severity at Visit 4 (Day 15) Using 7 Day Mean | Comparison of mean ocular discomfort severity between the KPI-121 0.25% ophthalmic suspension group and the vehicle group using a 0-100 visual analog grading scale where 0 was better and 100 was worse. | Baseline/Visit 2 (Day 1) to Visit 4 (Day 15) |
