Study Endpoints

Primary Endpoints

Mean Change From Baseline in Ocular Redness, Area Under the Curve From Time Zero to Hour 10 [AUC (0-10)] at Day 7
0.0, 0.25, 0.50, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, and 10.0 hours on Days 1 (baseline) and 7

Ocular redness ratings were collected for nasal and temporal areas of each eye and assessed by investigational center staff using a visual scale (ie, scored by comparing the subject's eye with a series of photographs) and graded on a scale from 0 (none) to 4 (extremely severe), 0.5 unit steps permitted. AUC was calculated using the trapezoidal rule with unequal intervals as determined by the assessment time points. Change was calculated as AUC(0-10)\[Day 7\] - AUC(0-10) \[Baseline\]. Both eyes contributed to the analysis.

Number of Adverse Events in Stage A
Day 1

Adverse events, including serious adverse events and deaths, were reported regardless of test article relationship.

Mean Change From Baseline in Nasal Congestion Over a 6-hour Period in the EEC at Day 5
Baseline (pretreatment), Day 5

Stage B: Nasal congestion was assessed by the subject before entering the EEC and at 14 timepoints over a 6-hour period after entering the EEC. Nasal congestion was scored on a scale from 0-3, where 0=none and 3=severe. Baseline EEC was conducted up to 21 days prior to the 5-day treatment period.

Secondary Endpoints

Mean Change From Baseline in Ocular Itching, Area Under the Curve From Time Zero to Hour 10 [AUC (0-10)] at Day 7
0.0, 0.25, 0.50, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, and 10.0 hours on Days 1 (baseline) and 7
