• Have a positive bilateral post-CAC reaction (defined as having scores of ≥2 ocular itching and ≥2 conjunctival redness) for at least two out of the first three time points following the challenge at Visit 2.

• depo-corticosteroids; Note: Currently marketed over-the-counter anti-allergy eye drops (i.e. anti-histamine/vasoconstrictor combination products such as Visine®-A®) may be administered to subjects by trained study personnel at the end of Visits 1, 2 and 4b after all evaluations are completed.
• Have any significant illness (e.g. any autoimmune disease requiring therapy, severe cardiovascular disease [including arrhythmias] the investigator feels could be expected to interfere with the subject's health or with the study parameters and/or put the subject at any unnecessary risk (includes but is not limited to: poorly controlled hypertension or poorly controlled diabetes, a history of status asthmaticus, organ transplants, a known history of persistent moderate or severe asthma, or a known history of moderate to severe allergic asthmatic reactions to any of the study allergens;
• Have received allergy immunotherapy within the last 2 years;
• Manifest signs or symptoms of clinically active allergic conjunctivitis in either eye at the start of Visits 1, 2, or 3 (defined as the presence of any itching or >1 [greater than 1] redness in any vessel bed);
