Primary Outcome Measures:
  • Ocular Itching Evaluated by the Subject 3 Minutes Post Challenge on Day 0 [ Time Frame: Day 0 at 3 Minutes Post Challenge ]
    Ocular itching is evaluated by the subject at 3 minutes post challenge on Day 0 (Visit 3B). Subjects score their ocular itching on a 9-point numeric analog scale ranging from 0=None to 4=Incapacitating Itch with an Irresistible Urge to Rub (0.5 increments are allowed). For each subject, the score for both eyes is averaged (i.e., one score per subject). A lower score is indicative of less itching.


Secondary Outcome Measures:
  • Ocular Itching Evaluated by the Subject at 5 and 7 Minutes Post Challenge on Day 0 [ Time Frame: Day 0 ]
    Ocular itching is evaluated by the subject at 5 and 7 minutes post challenge on Day 0 (Visit 3B). Subjects score their ocular itching on a 9-point numeric analog scale ranging from 0=None to 4=Incapacitating Itch with an Irresistible Urge to Rub (0.5 increments are allowed). For each subject, the score for both eyes is averaged (i.e., one score per subject). A lower score is indicative of less itching.

  • Percentage of Subjects With Minimal Itching Score at 3, 5, and 7 Minutes Post Challenge on Day 0 [ Time Frame: Day 0 ]
    Ocular itching is evaluated by the subject at 3, 5, and 7 minutes post challenge on Day 0 (Visit 3B). Subjects score their ocular itching on a 9-point numeric analog scale ranging from 0=None to 4=Incapacitating Itch with an Irresistible Urge to Rub (0.5 increments are allowed). For each subject, the score for both eyes is averaged (i.e., one score per subject). Minimal itching is considered a score <1.

  • Percentage of Subjects With a Zero Itch Score at 3, 5, and 7 Minutes Post Challenge on Day 0 [ Time Frame: Day 0 ]
    Ocular itching is evaluated by the subject at 3, 5, and 7 minutes post challenge on Day 0 (Visit 3B). Subjects score their ocular itching on a 9-point numeric analog scale ranging from 0=None to 4=Incapacitating Itch with an Irresistible Urge to Rub (0.5 increments are allowed). For each subject, the score for both eyes is averaged (i.e., one score per subject). Zero itch is considered a score = 0.

  • Percentage of Subject Eyes in Each Category of the Itching Score Distribution Post Challenge on Day 0 [ Time Frame: Day 0 ]
    Ocular itching is evaluated by the subject at Hour 16 post challenge on Day 0. Subjects score their ocular itching on a 9-point numeric analog scale ranging from 0=None to 4=Incapacitating Itch with an Irresistible Urge to Rub (0.5 increments are allowed).

  • Conjunctival Redness Evaluated by the Investigator at 7, 15, and 20 Minutes Post Challenge on Day 0 [ Time Frame: Day 0 ]
    The conjunctiva is a thin membrane that covers the inner surface of the eyelid and the white part of the eye. Conjunctival redness is evaluated by the investigator at 7, 15, and 20 minutes post challenge on Day 0 (Visit 3B). Investigators score conjunctival redness on a 9-point numeric analog scale ranging from 0=None to 4=Extremely Severe (0.5 increments are allowed). For each subject, the score for both eyes is averaged (i.e., one score per subject). A lower score is indicative of less conjunctival redness.

  • Ciliary Redness Evaluated by the Investigator at 7, 15, and 20 Minutes Post Challenge on Day 0 [ Time Frame: Day 0 ]
    Ciliary redness is redness spreading out around the cornea of the eye. Ciliary redness is evaluated by the investigator at 7, 15, and 20 minutes post challenge on Day 0 (Visit 3B). Investigators score ciliary redness on a 9-point numeric analog scale ranging from 0=None to 4=Extremely Severe (0.5 increments are allowed). For each subject, the score for both eyes is averaged (i.e., one score per subject). A lower score is indicative of less ciliary redness.

  • Episcleral Redness Evaluated by the Investigator at 7, 15, and 20 Minutes Post Challenge on Day 0 [ Time Frame: Day 0 ]
    The episclera is the tissue that lies over the white part of the eye. Episcleral redness is evaluated by the investigator at 7, 15, and 20 minutes post challenge on Day 0 (Visit 3B). Investigators score episcleral redness on a 9-point numeric analog scale ranging from 0=None to 4=Extremely Severe (0.5 increments are allowed). For each subject, the score for both eyes is averaged (i.e., one score per subject). A lower score is indicative of less episcleral redness.

  • Chemosis Evaluated by the Investigator at 7, 15, and 20 Minutes Post Challenge on Day 0 [ Time Frame: Day 0 ]
    Chemosis is swelling of the tissue that lines the eyelids and surface of the eye. Chemosis is evaluated by the investigator at 7, 15, and 20 minutes post challenge on Day 0 (Visit 3B). Investigators score chemosis on a 9-point numeric analog scale ranging from 0=None to 4=Severe (0.5 increments are allowed). For each subject, the score for both eyes is averaged (i.e., one score per subject). A lower score is indicative of less chemosis.

  • Eyelid Swelling Evaluated by the Subject at 7, 15, and 20 Minutes Post Challenge on Day 0 [ Time Frame: Day 0 ]
    Eyelid swelling is evaluated by the subject at 7, 15, and 20 minutes post challenge on Day 0 (Visit 3B). Subjects score eyelid swelling on a 4-point numeric analog scale ranging from 0=None to 3=Severe. For each subject, the score for both eyes is averaged (i.e., one score per subject). A lower score is indicative of less lid swelling.

  • Tearing Evaluated by the Subject at 7, 15, and 20 Minutes Post Challenge on Day 0 [ Time Frame: Day 0 ]
    Tearing is evaluated by the subject at 7, 15, and 20 minutes post challenge on Day 0 (Visit 3B). Subjects score 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 is averaged (i.e., one score per subject). A lower score is indicative of less tearing.
