Description

Inclusion Criteria:

• Be at least 18 years of age of either gender and any race;

• Have worn contact lenses within 7 days of Visit 1 or anticipate using contact lenses during the study;
• Have used any eye drops within 2 hours of Visit 1;
• Have previously had laser-assisted in situ keratomileusis (LASIK) surgery within the last 12 months;
• Have used ophthalmic cyclosporine or lifitegrast 5.0% ophthalmic solution within 90 days of Visit 1;
• Have any planned ocular and/or lid surgeries over the study period or any ocular surgery within 6 months of Visit 1;
• Have used temporary or permanent punctal plugs within 30 days prior to Visit 1 or anticipate their use during the study period

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Placebo Comparator: Vehicle Ophthalmic Solution QID to BID	Drug: Vehicle Ophthalmic Solution (0.25% Novel Formulation) QID to BID; Vehicle Ophthalmic Solution administered QID for four weeks, followed by BID administration for eight weeks
Experimental: Reproxalap (0.25% Novel Formulation) QID to BID	Drug: Reproxalap Ophthalmic Solution (0.25% Novel Formulation) QID to BID; Reproxalap Opthalmic Solution (0.25% Novel Formulation) administered QID for four weeks, followed by BID administration for eight weeks

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in Subject-reported Ocular Dryness Score (0 - 100 Visual Analogue Scale (VAS))	Change from baseline comparison of reproxalap to vehicle for subject-reported Ocular Dryness Score VAS (0 = no discomfort - 100 = maximal discomfort), where a higher score means a worse outcome. The intervention was administered bilaterally. The Least Squares Mean (standard error) was derived from mixed model repeated measures for change from baseline calculated using baseline score, treatment arm, visit, and the interaction of treatment arm and visit as fixed effects.	Efficacy assessment period (Day 1 through 85) - assessed at Weeks 1, 2, 4, 6, 8, 10, and 12. Baseline was Day 1.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Fluorescein staining	The method of assessment for this outcome is the Fluorescein staining Ora Calibra®	Efficacy assessment period (Week 2 through Week 12)
Unanesthetized Schirmer's Test	The method of assessment for this outcome is the Schirmer test strip.	Efficacy assessment period (Week 2 through Week 12)
