In 3 of the 4 studies, a larger reduction in ICSS favoring Xiidra was observed at 12 weeks1

The safety and efficacy of Xiidra compared to vehicle were studied in 2133 patients in 4 well-controlled, 12-week trials.1

Each of the 4 studies assessed the effect of Xiidra compared to vehicle on the signs and symptoms of Dry Eye Disease.1 Signs were assessed based on Inferior Corneal Staining Score (ICSS) on a scale of 0 to 4 in increments of 0.5. Results were reported as change from baseline at each visit.1

At 12 weeks, Xiidra reduced inferior corneal staining, as measured by the change in ICSS, compared to vehicle in 3 of the 4 studies (Studies 1, 2, and 4).1
