Primary Outcome Measures

Name	Time	Method
Ocular Itching at Day 7 (7 Minutes Post Conjunctival Allergen Challenge [CAC 6])	Baseline to Day 7 (7 minutes post CAC 6)	Ocular Itching was evaluated by participants and graded with Ophthalmic Research Associates, Inc. (ORA) Scale with the score ranged from 0 to 4 (0=none; 0.5=intermittent tickle in the cornea; 1=intermittent tickle more than just the cornea; 1.5=intermittent all-over tickling sensation; 2=mild conscious itch without desire to rub; 2.5=moderate, diffuse continuous itch with desire to rub; 3=severe itch with desire to rub; 3.5=severe itch improved with minimal rubbing; 4=incapacitating itch with an irresistible urge to rub) with 0.5 point increments allowed, and lower scores indicates lesser ocular itching. CAC is an initial titration challenge to determine the appropriate allergen and lowest concentration of allergen that produced a positive bilateral allergic response for each subject, defined as ≥ 2 score (0-4 point scale) in ocular itching and conjunctival redness within 10 minutes of the last titration of allergen.
Ocular Itching at Day 14 (7 Minutes Post CAC 9)	Baseline to Day 14 (7 minutes post CAC 9)	Ocular Itching was evaluated by participants and graded with Ophthalmic Research Associates, Inc. (ORA) Scale with the score ranged from 0 to 4 (0=none; 0.5=intermittent tickle in the cornea; 1=intermittent tickle more than just the cornea; 1.5=intermittent all-over tickling sensation; 2=mild conscious itch without desire to rub; 2.5=moderate, diffuse continuous itch with desire to rub; 3=severe itch with desire to rub; 3.5=severe itch improved with minimal rubbing; 4=incapacitating itch with an irresistible urge to rub) with 0.5 point increments allowed, and lower scores indicates lesser ocular itching.
Conjunctival Redness at Day 14 (20 Minutes Post CAC 9)	Baseline to Day 14 (20 minutes post CAC 9)	Conjunctival Redness was evaluated by an investigator with slit lamp and graded with ORA Scale with the score ranged from 0 to 4 (0=none; 1=mild-slightly dilated blood vessels; color of vessels is typically pink; can be quadrantal; 2=moderate-more apparent dilation of blood vessels; vessel color is more intense (redder); involves the majority of the vessel bed; 3=severe-numerous and obvious dilated blood vessels; in the absence of chemosis the color is deep red, may be less red or pink in presence of chemosis, is not quadrantic; 4=extremely severe-large, numerous, dilated blood vessels characterized by unusually severe deep red color, regardless of grade of chemosis, which involves the entire vessel bed) with 0.5 point increments allowed, and lower scores indicates reduction in the conjunctival redness.
Conjunctival Redness at Day 7 (20 Minutes Post CAC 6)	Baseline to Day 7 (20 minutes post CAC 6)	Conjunctival Redness was evaluated by an investigator with slit lamp and graded with ORA Scale with the score ranged from 0 to 4 (0=none; 1=mild-slightly dilated blood vessels; color of vessels is typically pink; can be quadrantal; 2=moderate-more apparent dilation of blood vessels; vessel color is more intense (redder); involves the majority of the vessel bed; 3=severe-numerous and obvious dilated blood vessels; in the absence of chemosis the color is deep red, may be less red or pink in presence of chemosis, is not quadrantic; 4=extremely severe-large, numerous, dilated blood vessels characterized by unusually severe deep red color, regardless of grade of chemosis, which involves the entire vessel bed) with 0.5 point increments allowed, and lower scores indicates reduction in the conjunctival redness.

Secondary Outcome Measures

Name	Time	Method
Ocular Itching at Day 6 (CAC 4), 5 (CAC 7)	Baseline to Day 6 (CAC 4), Day 13 (CAC 7) 7 minutes post CAC	Ocular Itching was evaluated by participants and graded with Ophthalmic Research Associates, Inc. (ORA) Scale with the score ranged from 0 to 4 (0=none; 0.5=intermittent tickle in the cornea; 1=intermittent tickle more than just the cornea; 1.5=intermittent all-over tickling sensation; 2=mild conscious itch without desire to rub; 2.5=moderate, diffuse continuous itch with desire to rub; 3=severe itch with desire to rub; 3.5=severe itch improved with minimal rubbing; 4=incapacitating itch with an irresistible urge to rub) with 0.5 point increments allowed, and lower scores indicates lesser ocular itching.
Conjunctival Redness at Day 6 (CAC 4), 5 (CAC 7)	Baseline to Day 6 (CAC 4), Day 13 (CAC 7) at 20 minutes post CAC	Conjunctival Redness was evaluated by an investigator with slit lamp and graded with ORA Scale with the score ranged from 0 to 4 (0=none; 1=mild-slightly dilated blood vessels; color of vessels is typically pink; can be quadrantal; 2=moderate-more apparent dilation of blood vessels; vessel color is more intense (redder); involves the majority of the vessel bed; 3=severe-numerous and obvious dilated blood vessels; in the absence of chemosis the color is deep red, may be less red or pink in presence of chemosis, is not quadrantic; 4=extremely severe-large, numerous, dilated blood vessels characterized by unusually severe deep red color, regardless of grade of chemosis, which involves the entire vessel bed) with 0.5 point increments allowed, and lower scores indicates reduction in the conjunctival redness.
