Outcome Measures
Primary Outcomes (2)
Mean Change From Baseline in Staff-Assessed Ocular Redness, Area Under the Curve From Time Zero to Hour 10 [AUC (0-10)], Maxidex and Placebo
Ocular redness ratings were collected for nasal and temporal areas of each eye and scored on a scale from 0 (none) to 4 (extremely severe), 0.5 unit steps permitted. The AUC computation was based on peak redness score (maximum of four areas of redness) at each time point (pre-treatment, 0.25, 0.5, 1.0, 1.5, 2.0, 2.5, 3 hours in the EEC and 3.5, 4, 5, 6, 7, 8, 9, 10 hours in the Clinic). The patient was dosed AM 30 minutes prior to entering the EEC (Visit 6). This outcome measure evaluates a late-phase effect, for which Maxidex vs. Placebo is the meaningful comparison.
Baseline (Visit 3, pre-treatment); Visit 6 (Day 9 of treatment)
Mean Change From Baseline Patient-Assessed Ocular Itching, Area Under the Curve From Time Zero to Hour 3 [AUC (0-3)], Patanol and Placebo
Ocular itching was scored a scale from 0 (none) to 4 (incapacitating itch with irresistible urge to rub) in 0.5 unit steps. The AUC computation was based on the score at each time point (pre-treatment, 0.25, 0.5, 1.0, 1.5, 2.0, 2.5, and 3 hours in the EEC). The patient was dosed AM 30 minutes prior to entering the EEC (Visit 5). This outcome measure evaluates an early-phase effect, for which Patanol vs. Placebo is the meaningful comparison.
Baseline (Visit 2, pre-treatment), Visit 5 (Day 8 of treatment)
