Inclusion criteria

* 18 years of age (either gender and any race); * Reported history of dry eye for at least 6 months prior to Visit 1; * Reported history of use or desire to use eye drops for dry eye symptoms within 6 months of Visit 1

Exclusion criteria

* Clinically significant slit lamp findings at Visit 1 that may include active blepharitis, meibomian gland dysfunction (MGD), lid margin inflammation, or active ocular allergies that require therapeutic treatment, and/or in the opinion of the investigator may interfere with study parameters; * Diagnosis of an ongoing ocular infection (bacterial, viral, or fungal), or active ocular inflammation at Visit 1; * Contact lens use within 7 days of Visit 1 or anticipate using contact lenses during the trial; * Eye drop use within 2 hours of Visit 1; * Previous laser-assisted in situ keratomileusis (LASIK) surgery within the last 12 months; * Cyclosporine 0.05% or 0.09% or lifitegrast 5.0% ophthalmic solution use within 90 days of Visit 1; * Be receiving systemic corticosteroid therapy (not including inhaled corticosteroids) within 14 days of Visit 1 or anticipate such therapy throughout the study period; * Planned ocular and/or lid surgeries over the study period or any ocular surgery within 6 months of Visit 1; * Temporary punctal plugs during the study that have not been stable within 30 days of Visit 1

Outcome results

Primary

Number of Subject Eyes That Are Schirmer Test Responders

Comparison of reproxalap to vehicle for number of subject eyes that are Schirmer test responders (10 millimeters or more increase from baseline). A generalized estimating equation analysis was performed with baseline as a covariate, and time point and treatment group as factors.

Time frame: The efficacy assessment period was before and after the final dose on Day 1 (Dose 4). Baseline was approximately two weeks before dosing at Screening.

Population: Intent-to-treat population with observed data only
