EDS scale from
0 to 100
EDS was rated by patients using a visual analogue scale (0=no discomfort, 100=maximal discomfort)
at each study visit.
Across all 4 Xiidra pivotal studies, average baseline EDS was 40-70.1
Based on analysis of covariance (ANCOVA) model adjusted for baseline value in Study 1, and ANCOVA model adjusted for baseline value and randomization stratification factors in Studies 2-4. All randomized and treated patients were included in the analysis and missing data were imputed using last-available data. In Study 1, one Xiidra-treated subject who did not have a baseline value was excluded from analysis.1
The safety and efficacy of Xiidra were assessed in four 12-week, randomized, multicenter, double-masked, vehicle-controlled studies (N=2133). Patients were dosed twice daily. The mean age was 59 years (range, 19-97 years). The majority of patients were female (76%). Use of artificial tears was not allowed during the studies. The study end points included assessment of signs (based on Inferior fluorescein Corneal Staining Score [ICSS] on a scale of 0 to 4) and symptoms (based on patient-reported EDS on a visual analogue scale of 0 to 100).1
The signs of dry eye disease
Xiidra was evaluated for its impact on the signs of dry eye disease in 4 robust clinical trials.1
