Positive Allergen-specific Immunoglobulin E (sIgE) tests for cat allergen and Fel d 1 (both ≥0.7 kUa/L) at screening visit 1 4. Must be able to complete the screening CACs to confirm moderate to severe cat allergen-induced allergic conjunctivitis as described in the protocol 5. Must not have lived with a cat(s) in the home for the past 3 years and must be willing to have no exposure to cat(s) at home throughout the study duration as described in the protocol Key Exclusion Criteria: 1.
