Group Intervention Description Placebo (dextran 70 0.1%/hydroxypropyl methylcellulose 0.3%) dextran 70 0.1%/hydroxypropyl methylcellulose 0.3% One drop of placebo instilled in each eye at Day 0 and Day 14. LASTACAFT® (alcaftadine 0.25%) alcaftadine 0.25% ophthalmic solution One drop of alcaftadine 0.25% ophthalmic solution instilled in each eye at Day 0 and Day 14. Pataday™ (olopatadine 0.2%) olopatadine 0.2% ophthalmic solution One drop of olopatadine 0.2% ophthalmic solution instilled in each eye at Day 0 and Day 14.
- Primary Outcome Measures
Name Time Method Ocular Itching Evaluated by the Subject at 3, 5, and 7 Minutes Post Challenge on Day 0 at Hour 16 Day 0 Hour 16 Ocular itching evaluated by the subject at 3, 5, and 7 minutes post challenge on Day 0 (Visit 3) at hour 16. Subjects scored their ocular itching on a numeric analog scale ranging from 0=None to 4=Incapacitating Itch with an Irresistible Urge to Rub (0.5 increments were allowed). For each subject, the score for both eyes was averaged (i.e., one score per subject). A lower score was indicative of less itching.
Ocular Itching Evaluated by the Subject at 3, 5, and 7 Minutes Post Challenge on Day 14 at Hour 24 Day 14 Hour 24 Ocular itching evaluated by the subject at 3, 5, and 7 minutes post challenge on Day 14 (Visit 4) at hour 24. Subjects scored their ocular itching on a numeric analog scale ranging from 0=None to 4=Incapacitating Itch with an Irresistible Urge to Rub (0.5 increments were allowed). For each subject, the score for both eyes was averaged (i.e., one score per subject). A lower score was indicative of less itching.
- Secondary Outcome Measures
Name Time Method Conjunctival Redness Evaluated by the Investigator at 7, 15, and 20 Minutes Post Challenge on Day 14 at Hour 24 Day 14 Hour 24 Conjunctival redness evaluated by the investigator at 7, 15, and 20 minutes post challenge on Day 14 (Visit 4) at hour 24. Investigators scored conjunctival redness on a numeric analog scale ranging from 0=None to 4=Extremely Severe (0.5 increments were allowed). For each subject, the score for both eyes was averaged (i.e., one score per subject). A lower score was indicative of less conjunctival redness.
Ciliary Redness Evaluated by the Investigator at 7, 15, and 20 Minutes Post Challenge on Day 14 at Hour 24 Day 14 Hour 24 Ciliary redness evaluated by the investigator at 7, 15, and 20 minutes post challenge on Day 14 (Visit 4) at hour 24. Investigators scored ciliary redness on a numeric analog scale ranging from 0=None to 4=Extremely Severe (0.5 increments were allowed). For each subject, the score for both eyes was averaged (i.e., one score per subject). A lower score was indicative of less ciliary redness.
Episcleral Redness Evaluated by the Investigator at 7, 15, and 20 Minutes Post Challenge on Day 14 at Hour 24 Day 14 Hour 24 Episcleral redness evaluated by the investigator at 7, 15, and 20 minutes post challenge on Day 14 (Visit 4) at hour 24. Investigators scored episcleral redness on a numeric analog scale ranging from 0=None to 4=Extremely Severe (0.5 increments were allowed). For each subject, the score for both eyes was averaged (i.e., one score per subject). A lower score was indicative of less episcleral redness.
Chemosis Evaluated by the Investigator at 7, 15, and 20 Minutes Post Challenge on Day 14 at Hour 24 Day 14 Hour 24 Chemosis evaluated by the investigator at 7, 15, and 20 minutes post challenge on Day 14 (Visit 4) at hour 24. Investigators scored chemosis on a numeric analog scale ranging from 0=None to 4=Severe (0.5 increments were allowed). For each subject, the score for both eyes was averaged (i.e., one score per subject). A lower score was indicative of less chemosis.
Eyelid Swelling Evaluated by the Subject at 7, 15, and 20 Minutes Post Challenge on Day 14 at Hour 24 Day 14 Hour 24 Eyelid swelling evaluated by the subject at 7, 15, and 20 minutes post challenge on Day 14 (Visit 4) at hour 24. Subjects scored eyelid swelling on a numeric analog 4-point scale ranging from 0=None to 3=Severe. For each subject, the score for both eyes was averaged (i.e., one score per subject). A lower score was indicative of less lid swelling.
Tearing Evaluated by the Subject at 7, 15, and 20 Minutes Post Challenge on Day 14 at Hour 24 Day 14 Hour 24 Tearing evaluated by the subject at 7, 15, and 20 minutes post challenge on Day 14 (Visit 4) at hour 24. Subjects scored tearing on a 5-point numeric analog scale ranging from 0=None/Normal to 4=Very Severe. For each subject, the score for both eyes was averaged (i.e., one score per subject). A lower score was indicative of less tearing.
