The purpose of this study is to evaluate the safety of topical ophthalmic 0.003% AR-15512 compared to its vehicle dosed twice daily (BID) in subjects with dry eye disease (DED) for 12 months.
At the end of the Screening Visit, subjects will undergo a protocol-specified washout period for prohibited prior and concomitant therapies. At the Baseline Visit, subjects who qualify based on inclusion/exclusion criteria will be enrolled in the study and randomized in a 2:1 ratio to receive 0.003% AR-15512 or AR-15512 Vehicle administered as 1 drop in each eye twice a day for 365 days (12 months). At the end of the Day 365 visit, subjects will exit the study. Aerie Pharmaceuticals was acquired by Alcon on November 22, 2022.

Ocular Treatment-Emergent Adverse Events by Preferred Term With Incidence Greater Than 2 Percent
A treatment-emergent adverse event was defined as any event that occurred or worsened on or after the day randomized study intervention was initiated. At each study visit, subjects were verbally asked by clinic staff to report any changes to any aspect of their ocular health. Ocular treatment-emergent adverse events reported by the subject or observed by the investigator were summarized by preferred term for overall incidence calculation. This was a subject-based assessment.

Mean Best Corrected Visual Acuity (BCVA) Letter Score by Visit
Visual acuity with correction in place (spectacles or a trial frame with lenses) was measured using Early Treatment Diabetic Retinopathy Study (ETDRS) letter charts (original or modified) at a distance of 10 feet. Each line on the ETDRS chart typically has five letters, and each letter correctly identified adds to the overall score. ETDRS letter scores range from 0 to 100, with each letter correctly identified representing a score of 1. A perfect score of 100 is achieved when all 70 letters on the chart are correctly identified. 85 letters correctly identified corresponds to normal distance eyesight.
