Inclusion criteria

1. Eighteen (18) to 70 years of age at the time of screening (either gender and any race) 2. Ability to provide written informed consent 3. Reported history of dry eye for at least 6 months prior to screening 4. Reported history of the use of eye drops for dry eye disease between 2 weeks to 6 months prior to screening

Exclusion criteria

1. Diagnosis of an ongoing ocular infection (bacterial, viral, or fungal), active ocular inflammation, or history of inflammatory disease (that, in the opinion of the Investigator, could interfere with study conduct or assessments) at screening 2. Contact lens use within 7 days of screening or anticipate using contact lenses during the trial 3. Systemic corticosteroid or other immunomodulatory therapy (not including inhaled corticosteroids) within 60 days of screening, or any planned immunomodulatory therapy throughout the study period 4. Women of childbearing potential (WOCBP) who are pregnant and nursing 5. If participant is of childbearing potential (female or male), unwillingness to use an acceptable means of birth control. 6. Known allergy and/or sensitivity to reproxalap or the drug product vehicle 7. A condition that the investigator feels may put the subject at significant risk, may confound the study results, or may interfere significantly with the subject's participation in the trial 8. Inability or unwillingness to follow instructions, including participation in all study assessments/procedures and visits

MeasureTime frameDescription
Conjunctival Redness Assessed Via Digital Photography Over 90 Minutes in the Dry Eye ChamberThe efficacy assessment period was during a 90-minute dry eye chamber; baseline was pre-dose #1 for each treatment period.Change from baseline comparison of reproxalap to vehicle for conjunctival redness assessed on a 0 to 4 scale (0 = none, 4 = extremely severe). The least squares mean (95% confidence interval) was derived from mixed model repeated measure for change from baseline included baseline as a covariate, and treatment, period, sequence, and time point as factors.
Schirmer Test Mean Change From BaselineThe efficacy assessment period was assessed on the first day of two consecutive dosing days for both crossover periods; baseline was pre-dose #1 for each treatment period.Change from baseline comparison of reproxalap to vehicle for schirmer test on a millimeter line (0 = none, 35 = maximum). The least squares mean (95% confidence interval) was derived from mixed model repeated measure for change from baseline included baseline as a covariate, and treatment, period, sequence, and time point as factors.

Conjunctival Redness Assessed Via Digital Photography Over 90 Minutes in the Dry Eye Chamber

Change from baseline comparison of reproxalap to vehicle for conjunctival redness assessed on a 0 to 4 scale (0 = none, 4 = extremely severe). The least squares mean (95% confidence interval) was derived from mixed model repeated measure for change from baseline included baseline as a covariate, and treatment, period, sequence, and time point as factors.

Time frame: The efficacy assessment period was during a 90-minute dry eye chamber; baseline was pre-dose #1 for each treatment period.

Schirmer Test Mean Change From Baseline

Change from baseline comparison of reproxalap to vehicle for schirmer test on a millimeter line (0 = none, 35 = maximum). The least squares mean (95% confidence interval) was derived from mixed model repeated measure for change from baseline included baseline as a covariate, and treatment, period, sequence, and time point as factors.

Time frame: The efficacy assessment period was assessed on the first day of two consecutive dosing days for both crossover periods; baseline was pre-dose #1 for each treatment period.
