Outcome Measures

Primary Outcomes (1)

  • Subject-Reported Ocular Itching Score Assessed in the Allergy Chamber

    The method of assessment was a 9-point ocular itch scale measured in half-unit increments (0 none - 4 severe) with a higher score representing worse symptomology. Subjects were dosed once just prior to allergen chamber entry and again halfway through the chamber. The allergen chamber was 210 ten minutes in duration with the itching assessment being collected every 10 minutes from 110 to 210 minutes. The timepoints were assessed using mixed model repeated measures.

    110 to 210 minutes during allergen chamber exposure

Secondary Outcomes (1)

  • Conjunctival Redness Evaluated by the Investigator

    12 to 212 minutes during allergen chamber exposure
